[0036] The following will be combined with the drawings of the specific embodiments of the utility model to clearly and completely describe the exemplary scheme of the utility model. Unless otherwise defined, the technical terms or scientific terms used in the utility model should be the common meanings understood by people with ordinary skills in the relevant field.

[0037] like Figure 1 and Figure 3 As shown, the kitchen waste dehydration treatment device of this embodiment includes a receiving bin 100, a dehydration chamber 200, an extrusion piece 300, a drainage pipe 400 and an active valve 500. The receiving bin 100 is used to receive kitchen waste; the dehydration chamber 200 includes a dehydration barrel 220 and a dehydration chamber 210, the dehydration barrel 220 is arranged in the dehydration chamber 210, and the feed port of the dehydration barrel 220 is connected and fixed with the left end of the receiving bin 100; the extrusion piece 300 is connected and fixed with the right end of the receiving bin 100, and the extrusion piece 300 is used to provide power for the kitchen waste extrusion dehydration in the dehydration chamber 200; the drainage pipe 400 is connected with the discharge port of the dehydration barrel 220; the active valve 500 is arranged on the pipeline connecting the dehydration barrel 220 and the drainage pipe 400, and the active valve 500 is used to control the connection and disconnection between the dehydration barrel 220 and the drainage pipe 400.

[0038] Furthermore, the material receiving bin 100 and the dewatering barrel 220 as well as the material receiving bin 100 and the extrusion piece 300 are connected by flanges and bolts.

[0039] Preferably, the movable valve 500 is a hydraulic gate valve, and a flexible metal pad is adhered to the surface of the hydraulic gate valve to ensure the sealing contact between the hydraulic gate valve and the dehydration barrel 220.

[0040] like Figure 3 As shown, a plurality of dehydration holes 221 are evenly opened in the circumferential direction on the dehydration barrel 220 , and the dehydration holes 221 are arranged in the dehydration chamber 210 in the horizontal direction.

[0041] Furthermore, the dehydration holes 221 are in an elongated shape, and the width of the elongated dehydration holes 221 is smaller than the size of common kitchen waste. A plurality of dehydration holes 221 form a dehydration hole group vertically, and the plurality of dehydration hole groups are evenly distributed on the dehydration barrel 220 horizontally.

[0042] For example, the plurality of dehydration holes 221 are divided into five dehydration hole groups. The dehydration hole groups are arranged at intervals in the left-right direction. The dehydration holes 221 of each dehydration hole group are arranged at intervals in the circumferential direction of the dehydration barrel 220 .

[0043] For example, the dehydration hole 221 can be processed using a high-power laser cutting machine. The size of the dehydration hole 221 in the left-right direction is 80 mm, the size of the dehydration hole 221 in the circumferential direction of the dehydration barrel 220 is 4-8 mm, and the interval between two adjacent dehydration holes 221 in the circumferential direction is 6 mm.

[0044] like Figure 3 As shown, a plurality of annular reinforcing ribs 222 are arranged at intervals on the outer wall of the dehydration barrel 220 to improve the strength of the dehydration barrel 220 and prevent the dehydration barrel 220 from being squeezed and broken.

[0045] Furthermore, the reinforcing ribs 222 and the dehydration holes 221 are arranged perpendicular to each other, and each reinforcing rib 222 and each dehydration hole group are arranged alternately.

[0046] For example, the number of the reinforcing ribs 222 is 6, and the thickness of the reinforcing ribs 222 is 14 mm.

[0047] like Figure 3 As shown, a plurality of spray heads 211 are evenly arranged on the inner wall of the dehydration chamber 210 , and the spray heads 211 are used to spray high-pressure water flow into the dehydration chamber 210 .

[0048] Furthermore, the shower head 211 is connected to an external water source.

[0049] Furthermore, each spray head 211 is arranged corresponding to each dehydration hole group. After the dehydration process is completed, the high-pressure water flow sprayed by the spray head 211 can effectively clean the residual kitchen waste slurry attached to the dehydration barrel 220, avoiding the dehydration hole 221 from being blocked and affecting the next use.

[0050] In addition, the flow rate of the water sprayed from the spray head 211 is adjustable, that is, the flow rate of the water is adjusted according to the actual situation of the residual kitchen waste slurry attached to the dewatering barrel 220.

[0051] like Figure 3 As shown, the bottom of the dehydration chamber 210 is connected with a drain groove 230, and the drain groove 230 is funnel-shaped. Further, the bottom of the drain groove 230 is connected with an elbow 231, and the bending degree of the elbow 231 can be adjusted according to actual needs.

[0052] like Figure 2 and Figure 4 As shown, a first stop 130 is provided at the connection between the receiving bin 100 and the dewatering barrel 220, and a second stop 140 is provided at the connection between the receiving bin 100 and the extrusion member 300, and the first stop 130 and the second stop 140 have the same structure.

[0053] Further, the first stopper 130 includes a concave stopper 131 and a convex stopper 132, wherein the concave stopper 131 is installed on the receiving bin 100, and the convex stopper 132 is installed on the dewatering barrel 220. The use of the concave stopper 131 and the convex stopper 132 ensures the sealed connection between the receiving bin 100 and the dewatering barrel 220.

[0054] Similarly, the second stopper 140 includes a concave stopper 131 and a convex stopper 132, wherein the concave stopper 131 is installed on the receiving bin 100, and the convex stopper 132 is installed on the extrusion piece 300. The use of the concave stopper 131 and the convex stopper 132 ensures the sealed connection between the receiving bin 100 and the extrusion piece 300.

[0055] like Figure 1 and Figure 2 As shown, the extrusion component 300 includes an extrusion body 310, a push rod 320 and a telescopic cylinder 330. The extrusion body 310 is connected and fixed to the material receiving bin 100, and a through hole 340 is opened in the left and right directions of the extrusion body 310; the push rod 320 is arranged in the through hole 340, and the telescopic cylinder 330 is fixedly arranged outside the extrusion body 310, and one end of the push rod 320 is connected to the output end of the telescopic cylinder 330.

[0056] like Figure 1 and Figure 2 As shown, the telescopic cylinder 330 , the push rod 320 and the dewatering barrel 220 are coaxial, and the telescopic cylinder 330 drives the push rod 320 to reciprocate in the receiving bin 100 and the dewatering barrel 220 .

[0057] Furthermore, the movable valve 500 and the telescopic cylinder 330 of this embodiment are controlled by an external controller.

[0058] Furthermore, the pressure value and the pressure holding time output by the telescopic oil cylinder 330 are adjustable. The pressure value and the pressure holding time can be adjusted according to the actual state of the kitchen waste to be processed.

[0059] For example, the pressure value is set to 35 Bar and the pressure holding time is set to 1 minute. In this embodiment, the pressure value and the pressure holding time are not limited. The pressure value and the pressure holding time of kitchen waste in different states are different. The specific settings are determined according to the actual situation. According to field tests, kitchen waste with larger particle size generally requires a slightly longer pressure holding time, and kitchen waste with smaller particle size requires a slightly shorter pressure holding time.

[0060] Furthermore, the movement speed of the push rod 320 can be adjusted according to the actual state of the food waste to be processed. For example, the movement speed of the push rod 320 is 80 mm per second. The movement speed of the push rod 320 is controlled by the flux of the telescopic cylinder 330. By adjusting the movement speed of the push rod 320, various food wastes can be squeezed evenly, thereby improving the dehydration effect.

[0061] Furthermore, the processing capacity of the dehydration treatment device in this embodiment is 10 cubic meters per hour.

[0062] like Figure 1 and Figure 2As shown, a feed inlet 110 is provided at the top of the receiving bin 100, and inspection ports 120 are provided at the front and rear sides. The kitchen waste enters the receiving bin 100 from the feed inlet 110, and then enters the dehydration barrel 220 under the push of the push rod 320.

[0063] Furthermore, the inspection opening 120 is an openable and closable structure, and a transparent material is used for the inspection opening 120. The staff can observe the internal situation of the receiving bin 100 from the inspection openings 120 on both sides, or open the inspection openings 120 to repair the receiving bin 100.

[0064] The dehydration treatment device of this embodiment further includes a machine base 600 , and the material receiving bin 100 , the dehydration chamber 200 , the extrusion piece 300 , the sewage pipe 400 and the movable valve 500 can be installed on the machine base 600 .

[0065] Optionally, the dehydration treatment device of the present invention further includes a lubrication station 700 , which is fixedly mounted on the machine base 600 and is used for lubricating and maintaining the telescopic cylinder 330 .

[0066] How this application works is:

[0067] The pressure value and pressure holding time of the telescopic oil cylinder 330 are set according to the actual kitchen waste to be processed.

[0068] The movable valve 500 is controlled by an external controller to move downward until it is in complete sealing contact with the dehydration barrel 220, and the kitchen waste is loaded into the receiving bin 100 through the feed inlet 110. Then, the telescopic cylinder 300 is started, and the push rod 320 is driven to push the kitchen waste in the receiving bin 100 into the dehydration barrel 220.

[0069] The push rod 320 continues to push the kitchen waste in the dehydration barrel 220 until the pushing pressure reaches the set pressure value, the kitchen waste is pressed and continuously squeezes out water, and the squeezed water flows out of the drainage groove 230 through the dehydration hole 221. The push rod 320 continues to squeeze the kitchen waste in the receiving bin 100 until the pressure holding time is reached.

[0070] When the kitchen waste is squeezed and dehydrated in the dehydration barrel 220, the spray head 211 is turned on. The sprayed water flow cleans the kitchen waste slurry attached to the side wall of the dehydration barrel 220 and flows out from the drainage groove 230. After the side wall of the dehydration barrel 220 is cleaned, the spray head 211 is turned off.

[0071] Then the movable valve 500 is controlled to move upward, and the dehydration chamber 200 is connected to the sewage pipe 400. The push rod 320 continues to push forward to discharge the dehydrated kitchen waste from the sewage pipe 400.

[0072] Finally, the telescopic cylinder 300 contracts and drives the push rod 320 back into the extrusion body 310 .

[0073] At this point, the dehydration treatment device of the utility model has completed a dehydration treatment of kitchen waste. By repeating the above actions, the kitchen waste can be effectively treated.

[0074] When the dehydration process is completed, there will be residual kitchen waste slurry attached to the dehydration barrel 220. At this time, the spray head 211 sprays running water to wash down the kitchen waste slurry and discharge it from the drainage groove 230.
