Furthermore, the wet curtain mounting frame 1 and the bottom plate 2 with a V-shaped groove are made from aluminium alloys; and trim strips are adopted as the buckles of the reel 6 and the reel 10 to fix the wet curtain. In addition, the wet curtain net is a common plastic net or sun-shade net on the market.

(6) The pig production method by using a detachable and washable wet curtain is characterized in that:

(7) (1) Mounting of the wet curtain

(8) The wet curtain is mounted in a V shape at an included angle of 10°-20° by means of the reels. One end of the wet curtain enters the wet curtain mounting frame from the reel 6 with a buckle, passes through the plurality of reels, and finally comes out of the reel 10 with a buckle; two ends of the wet curtain are respectively fixed to the reel 6 and the reel 10 by means of their buckles; and the wet curtain is tensioned by rotating the manual handle 9.

(10) The wet curtain is unbuckled from the reel 6 first, then detached by rotating the manual handle 9, and finally unbuckled from the reel 10 to be removed; and the removed wet curtain is washed in a pool.

(11) The wet curtain net 8 is wound around the reels at the included angle of 10°-20°. An accessary draught fan is required by the wet curtain for a pig farm. The accessary draught fan and the wet curtain are respectively located at two ends of a pigsty. The accessary draught fan blows air out of the pigsty; and the wet curtain is used to lower the temperature in the pigsty when it reaches 28° C. in summer.

(12) The pig production method by using a detachable and washable wet curtain in an embodiment is characterized in that:

(13) (1) Structure of the wet curtain

(14) A wet curtain device includes an aluminium alloy frame 1, an aluminium alloy bottom plate 2 (with a V-shaped groove in the middle), a water outlet 3 (a polyethylene (PE) or polyvinyl chloride (PVC) tube with an outer diameter about 25 mm), a spray tube 4 (a PE or PVC tube with an outer diameter about 25 mm), a water inlet 5 (a PE or PVC tube with an outer diameter about 25 mm), a reel 6 with a buckle (a trim strip is adopted as the buckle of the reel 6 to fix the wet curtain, and the rotating shaft is a rotatable sleeve), reels 7 (which are rotatable sleeves), a wet curtain net 8 (equivalent to a commonly known “new material net” made from high-density polyethylene), and a reel 10 with a buckle (a time strip is adopted as the buckle of the reel 10 to fix the wet curtain, and the reel 10 is a rotatable sleeve). In addition, all materials have specifications meeting the national standard.

(15) As shown in FIG. 1 and FIG. 2, the aluminium alloy frame 1 is 200 cm long, 160 cm high, and 16 cm wide. Water enters the spray tube 4 (fixed in the top of the aluminium alloy frame 1) via the water inlet 5; and the water sprayed from the spray tube flows through the wet curtain net 8, then enters the V-shaped groove in the aluminium alloy bottom plate 2, and finally flows out of the water outlet 3. The rotating shaft 6 with a buckle, the rotating shafts 7, the rotating shaft 10 with a buckle, and the manual handle 9 are used to fix the wet curtain; one end of the wet curtain enters the aluminium alloy frame 1 from the reel 6 with a buckle, passes through a plurality of reels 7 fixed in the aluminium alloy frame 1, and finally comes out of the reel 10 with a buckle (used to fix the wet curtain), where the wet curtain is wound around the reels at an included angle of about 15°; and the wet curtain is tensioned by rotating the manual handle 9 connected to the reel 10 with a buckle.

(16) (2) Material selection of the wet curtain

(17) A common plastic net or sun-shade net, namely the commonly known “new material net” made from the high-density polyethylene, is selected to form the wet curtain; it is better to adopt a three-strand net or four-strand net (there are three wefts within one inch in the three-strand net and four wefts within one inch in the four-strand net). There are many brands, such as Courtyard Flower, Deteng, Xia Zhiyan, and Caiyou, of the plastic net. The plastic net is soft and thus is very convenient to detach and wash.

(18) (3) Mounting of the wet curtain

(19) The wet curtain is mounted in a V shape at the included angle of about 15° by means of the reels. One end of the wet curtain enters the aluminium alloy frame 1 from the reel 6 with a buckle, passes through the plurality of reels, and finally comes out of the reel 10 with a buckle; two ends of the wet curtain are respectively fixed to the reel 6 and the reel 10 by means of their buckles; and the wet curtain is tensioned by rotating the manual handle 9.

(20) (4) Detachment and washing of the wet curtain

(21) The wet curtain is unbuckled from the reel 6 first, then detached by rotating the manual handle 9, and finally buckled from the reel 10 to be removed; and the removed wet curtain is washed in a pool to get rid of dust, scale, algae, mosquitoes, flies, and the like.

(22) (5) Accessary draught fan

(23) The accessary draught fan is required by the wet curtain for the pig farm (the accessary draught fan and the wet curtain are respectively located on the two ends of the pigsty); and the accessary draught fan performs longitudinal ventilation at a negative pressure, that is, the accessary draught fan sucks the air from the outside.

(24) (6) Requirement on water quality

(25) The wet curtain formed by the plastic net has no special requirement on the water quality, and both well water and tap water can be used.

(26) (7) Usage of the wet curtain in the pigsty

(27) The wet curtain needs to be used to lower the temperature in the pigsty when it reaches 28° C. in summer.

(28) The wet curtain in the present disclosure has been used for a pig farm in the Lvye Ecological Park in Jingjiang City, and the effect of the wet curtain in the present disclosure on pig production is compared with that of a traditional wet curtain formed by a honeycomb made from special paper on the pig production in Table 2. In summer, namely a high-temperature season, the wet curtain in the present disclosure has similar cooling effects, and a temperature difference is only about 1° C.; daily gains of pigs have no obvious difference; and mounting, detachment, washing, and replacement costs of the wet curtain in the present disclosure only account for ½ of those of the traditional wet curtain formed by the honeycomb made from the special paper, and the cost of the wet curtain in the present disclosure only accounts for ⅕ of that of the traditional wet curtain formed by the honeycomb made from the special paper.
