Description

Technical Field

[0001] The utility model relates to the field of water-powder sieves, in particular to a water-powder sieve for separating particle water. Background Art

[0002] The mixing, extrusion, and granulation unit can mix, plasticize, extrude, pelletize, separate, and dry materials, ultimately processing them into regular granular products. It mainly consists of a metering, feeding, and mixing system, a melt mixing system, an extrusion granulation system, and a granule post-processing system. The granule post-processing system includes a water tank, a gouache screen, a plate heat exchanger, a dryer, and a vibrating screen. A water pump is installed on the water tank's outlet pipe, which can transport circulating water from the water tank to the plate heat exchanger. The plate heat exchanger then transports the cooled circulating water to the water chamber. The dryer separates the material particles from the circulating water sent from the water chamber. The circulating water separated by the dryer is transported to the gouache screen through the water inlet pipe. The gouache screen is installed on the top of the water tank. Return pipes are installed on the bottom side of the gouache screen and the top side of the water tank to facilitate the return of the screened circulating water to the water tank. Existing gouache screens are ineffective in screening water containing waste particles and are difficult to maintain. Utility Model Content

[0008] The utility model is provided with a guide plate and a water baffle in the sieve body. The guide plate can directly guide the water flow to the inlet side where the screen is higher. The water baffle can block the water flow above the screen to prevent the water flow from passing over the inlet side and directly falling to the outlet side from above the screen. The blocked water is guided to the inlet side, thereby ensuring that the water entering the sieve body will fully flow over the screen, thereby improving the screening effect. The cover of the utility model can be controlled by a gas spring to rotate open or close, and the screen can be retracted in the sieve body by the winding shaft. At this time, the screen or any part of the sieve body can be easily inspected and repaired, which is extremely convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] With reference to the accompanying drawings, the specific implementation is as follows:

[0014] like Figure 1 As shown, a water-powder sieve for separating particle water includes a sieve body 3 installed on the top of a water tank 1, a sieve 7, a guide plate 5 and a water baffle 6 installed in the sieve body 3, the outlet side of the sieve 7 faces the discharge channel of the sieve body 3, the inlet side of the sieve 7 is higher than the outlet side, and the middle part of the sieve 7 is connected to the winding shaft 11, as shown in FIG. Figure 3 As shown, the ends of the mesh winding shaft 11 are rotatably mounted on the side walls of the screen body 3 through shaft sleeves 12. End caps 13 are installed in the side walls of the screen body 3. The shaft sleeves 12 are inserted into the blind holes of the end caps 13. A sealing gasket 14 is provided between the end caps 13 and the side walls of the screen body 3. The mesh winding shaft 11 can be used to retract the screen 7 within the screen body for easy maintenance. A plurality of reinforcing rods 15 are provided in the screen body 3, and the ends of the reinforcing rods 15 are respectively connected to the two opposite inner walls of the screen body 3.

[0015] like Figure 2 As shown, the guide plate 5 is close to the side wall of the sieve body 3 on which the water inlet pipe 2 is installed. The guide plate 5 has a water storage section and a guide section. The water storage section and the inner wall of the sieve body 3 cooperate to form a water storage cavity. The top edge of the guide section and the top edge of the water storage section are smoothly connected. The guide section is inclined and the bottom edge is close to the inlet side of the screen 7, so that the water in the water storage cavity flows along the guide section to the inlet side of the screen 7, and then is screened in the process of the water flowing through the screen 7.

[0016] like Figure 2 As shown, the water baffle 6 is located above the screen 7, and the bottom edge of the water baffle 6 is also close to the inlet side of the screen 7. The water baffle 6 can block the water flowing from above the screen 7 toward the outlet side of the screen 7, and make the blocked water flow along the water baffle 6 to the inlet side of the screen 7, preventing the water flow from above the screen 7 over the inlet side and directly falling to the outlet side, ensuring that the water entering the screen body 2 will fully flow over the screen 7, thereby improving the screening effect.

[0017] like Figure 2As shown, the bottom surface of the inner cavity of the sieve body 3 is provided with a water outlet 8 and multiple sections of inclined surfaces. The water outlet 8 is located at the lowest end of the inclined surface and is connected to the water tank 1, so that the screened water flows back to the water tank 1. The sieve body 3 is provided with a cover plate 4 installed on one side of the discharge channel. The top of the cover plate 4 is rotatably connected to the top of the sieve body 3. A buckle 10 is installed between the bottom side of the cover plate 4 and the sieve body 3. The side wall of the cover plate 4 is hinged to one end of a gas spring 9, and the other end of the gas spring 9 is hinged to the sieve body 3. The expansion and contraction of the gas spring 9 can drive the cover plate 4 to rotate between the closed position and the open position when the buckle 10 is released, and the gas spring 9 can keep the cover plate 4 in the jacked-up position, which is convenient for inspection and maintenance operations.
