Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0023] The present utility model provides a technical solution: As Figure 1-2 , Figure 4-5As shown in the figure, in this embodiment, a kitchen waste grading and pressing device includes a kitchen waste grading and pressing mechanism 100 and a clogging prevention component 200. The kitchen waste grading and pressing mechanism 100 includes a grading and pressing outer shell 101. An arc-shaped outlet 106 is provided at one end of the grading and pressing outer shell 101. An arc-shaped plate 201 is arranged inside the arc-shaped outlet 106, and the arc-shaped plate 201 can move inside the arc-shaped outlet 106. A through hole 202 is formed inside the arc-shaped plate 201, and the through hole 202 is used to extrude and discharge the dehydrated solid waste. The aperture of the through hole 202 of the arc-shaped plate 201 is adapted to the diameter of the ejector pin 211, and the ejector pin 211 can move inside the through hole 202 of the arc-shaped plate 201 and remove the solid blockage inside the through hole 202 of the arc-shaped plate 201. One end of the ejector pin 211 is fixedly connected to the end of the second fixing bracket 104 through a fixing bolt 212. One end of the second fixing bracket 104 is fixedly connected to the mounting plate 205 by welding. The upper end of the mounting plate 205 is fixedly connected to the telescopic hydraulic cylinder 204 by bolts. One end of the telescopic hydraulic cylinder 204 is provided with a telescopic cylinder 206. A telescopic guide post 207 passes through the inside of the telescopic cylinder 206. The telescopic guide post 207 is fixedly installed at one end of the telescopic hydraulic cylinder 204. One end of the telescopic guide post 207 is fixedly connected to the arc-shaped plate 201 by bolts.

[0024] As Figure 1-2 , Figure 4 shown, one end of the arc-shaped plate 201 is fixedly connected to the support guide post 209 by bolts. The support guide post 209 is installed inside the guide sleeve 208. The guide sleeve 208 is connected to one end of the second fixing bracket 104 by bolts.

[0025] When the crushed solid of kitchen waste is poured into the interior of the grading and pressing housing 101 from the feed inlet 102, the solid and liquid of the kitchen waste are pressed and separated. After that, the solid of the kitchen waste after liquid separation is extruded and discharged from the hole 202 of the arc plate 201 at the arc-shaped outlet 106 of the grading and pressing housing 101. In order to avoid the blockage of the hole 202 of the arc plate 201 at the arc-shaped outlet 106 of the grading and pressing housing 101, by driving the telescopic hydraulic cylinder 204, the telescopic guide post 207 can move inside the telescopic cylinder 206. The movement of the telescopic guide post 207 further drives the arc plate 201 to move out from the arc-shaped outlet 106 of the grading and pressing housing 101. When the arc plate 201 moves to the outside, the hole 202 of the arc plate 201 will move to the position of the ejector pin 211, and the hole 202 of the arc plate 201 reciprocates on the ejector pin 211, further cleaning and dredging the blocked solid of the kitchen waste inside the hole 202 of the arc plate 201. It can effectively avoid the blockage inside the hole 202 of the arc plate 201, and ensure that the arc plate 201 and the arc-shaped outlet 106 of the grading and pressing housing 101 are cleaned regularly. After that, the support guide post 209 can move inside the guide sleeve 208, and the support guide post 209 can further support the stable horizontal movement of the arc plate 201.

[0026] As Figure 2-4 shown, the arc-shaped outlet 106 of the grading and pressing housing 101 is provided with a leak-proof groove 203. The structural shape of the leak-proof groove 203 is adapted to the structural shape of the leak-proof arc-shaped pad 210. The leak-proof arc-shaped pad 210 is closely attached to the inside of the leak-proof groove 203 by moving and inserting, and the leak-proof arc-shaped pad 210 is fixedly installed at the upper end of the arc plate 201.

[0027] When the arc plate 201 moves into the arc-shaped outlet 106, the leak-proof arc-shaped pad 210 can further move to the position of the leak-proof groove 203 for fitting. When the solid of the kitchen waste is pressed, it can prevent the moisture of the kitchen waste from penetrating out from the arc-shaped outlet 106 of the grading and pressing housing 101.

[0028] As Figure 1-3 、 Figure 6As shown, a fixed block 107 is fixedly installed at the position of the arc-shaped outlet 106 of the grading press housing 101. One end of the screw press shaft 109 passes through and is connected inside the fixed block 107. One end of the screw press shaft 109 is installed inside the rolling bearing 108. The rolling bearing 108 is bolted to one end of the fixed block 107. The screw press shaft 109 is installed inside the grading press housing 101. A filter hole 113 is opened at the lower end of the grading press housing 101. The filter hole 113 can filter out the moisture of the food waste and discharge it outside the grading press housing 101. One end of the grading press housing 101 is connected and fixed with a first fixing piece 110 by bolts. The first fixing piece 110 is connected and fixed with a second fixing piece 111 by bolts. The second fixing piece 111 is connected and fixed with a servo motor 112 by bolts. One end of the servo motor 112 is installed with one end of the screw press shaft 109. A first fixing bracket 103 is installed at the lower end of the grading press housing 101. Separating the moisture of the food waste solid by the screw press shaft 109 in this grading press device is a conventional method in the prior art. By driving the servo motor 112 to drive the screw press shaft 109 to rotate inside the grading press housing 101, the working principle of the screw press shaft 109 is to utilize the centrifugal force and extrusion force generated when the spiral rotates to separate the moisture from the food waste solid. Specifically, when the servo motor 112 drives the screw press shaft 109 to rotate, the blades on the spiral will push the food waste solid towards the inner wall of the housing and form a thin layer of material. As the spiral rotates continuously, the material layer will be subjected to increasing pressure, thereby squeezing out the moisture in it.

[0029] The utility model provides a kitchen waste grading and pressing device, and the specific working principle is as follows: When the crushed solid of kitchen waste is poured into the inside of the grading and pressing housing 101 from the feed inlet 102, the solid and liquid of the kitchen waste are pressed and separated. After that, the solid of the kitchen waste after liquid separation is extruded and discharged from the hole 202 of the arc plate 201 at the arc-shaped outlet 106 of the grading and pressing housing 101. In order to avoid the blockage of the hole 202 of the arc plate 201 at the arc-shaped outlet 106 of the grading and pressing housing 101, the driving telescopic hydraulic cylinder 204 drives the telescopic guide post 207 to move inside the telescopic cylinder 206. The movement of the telescopic guide post 207 further drives the arc plate 201 to move out from the arc-shaped outlet 106 of the grading and pressing housing 101. When the arc plate 201 moves to the outside, the hole 202 of the arc plate 201 will move to the position of the ejector pin 211, and the hole 202 of the arc plate 201 reciprocates on the ejector pin 211 to further clean and dredge the blocked solid of the kitchen waste inside the hole 202 of the arc plate 201, effectively avoiding the blockage inside the hole 202 of the arc plate 201. After that, the support guide post 209 can move inside the guide sleeve 208, and the support guide post 209 further supports the stable horizontal movement of the arc plate 201. When the arc plate 201 moves into the arc-shaped outlet 106, the leak-proof arc-shaped pad 210 can move to the leak-proof groove 203 for fitting. When the solid of the kitchen waste is pressed, the moisture of the kitchen waste can be prevented from leaking out from the arc-shaped outlet 106 of the grading and pressing housing 101.
