DETAILED DESCRIPTION

[0041] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Those skilled in the art will be able to implement the present invention based on these descriptions. Furthermore, the embodiments of the present invention described below are generally only some, not all, of the embodiments of the present invention. Therefore, all other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.

[0042] like Figure 3 The small-scale distributed on-site treatment equipment for perishable waste shown includes a treatment chamber 1 with an internal stirring shaft 11. The internal space is divided into a first area 13 and a second area 14 by a vertical partition 12, with an overflow port on the partition 12. Kitchen waste can be fed into the first area 13 through the feeding port 15 at the top of the treatment chamber 1 and thoroughly mixed with microbial inoculants by the spiral stirring shaft 11. During the mixing process, the spiral stirring shaft 11 pushes the kitchen waste towards the first area 13, keeping undegraded or insufficiently degraded kitchen waste away from the second area 14. Conversely, the undegraded or insufficiently degraded kitchen waste will squeeze the fully degraded organic fertilizer towards the second area 14, allowing the degraded organic fertilizer to enter the second area 14 through the overflow port. Thus, when the discharge port 16 is opened, the organic fertilizer is discharged from the second area 14.

[0043] The food waste treatment equipment has an insulated chamber 2 located below the treatment chamber 1. An air inlet pipe 21 and an air outlet pipe 22 are located above the treatment chamber 1. The air inlet pipe 21 communicates with the interior of the treatment chamber 1. One end of the air outlet pipe 22 connects to the treatment chamber 1, and the other end connects to the first side of the insulated chamber 2. A first pipe 23 is installed on the second side of the insulated chamber 2 opposite to the first side. The first pipe 23 is connected to a suction fan 24, and the air outlet of the suction fan 24 is connected to a second pipe 25. A housing 3 is installed on the air outlet pipe 22, and the internal cavity of the housing 3 communicates with the interior of the air outlet pipe 22. A heating element 31 and a deodorizing element 32 are installed inside the housing 3. The heating element 31 includes a shell with ventilation openings and an electric heating wire installed inside. The deodorizing element 32 has a honeycomb structure and a deodorizing coating on its surface.

[0044] By suction of the suction fan 24, the external fluid can flow from the air inlet pipe 21 into the treatment cabin 1, then from the air outlet pipe 22 into the heat preservation cabin 2, and finally from the heat preservation cabin 2. When the fluid passes through the box body 3 on the air outlet pipe 22, it is heated by the heating element 31 inside the box body 3 and deodorized by the deodorizing element 32, so that there is no odor when the fluid is discharged. At the same time, the heated fluid heats the treatment cabin 1 when passing through the heat preservation cabin 2 to meet the temperature requirement of microorganism reproduction. Finally, the fluid is discharged to the lower part of the entire device through the second pipeline 25, so that people passing by the device will not be affected by the discharged fluid. And the second pipeline 25 adopts a soundproof pipe to reduce wind noise.

[0045] As shown in Figure 4 , Figures 7 to 10 , a filter is arranged at the port position of the air outlet pipe 22 to filter out particles brought in by the fluid to avoid burning of the heating element 31. As shown in Figures 10 to 12 , the filter comprises a main body 4, which is hollow inside to allow fluid to pass through; an opening 41 is arranged at the lower part of the main body 4 for fluid to enter; a frame 5 is arranged below the main body 4, and the frame 5 has a filter sponge 6, which is tightly pressed against the lower end face of the main body 4 and covers the opening 41; after being filtered by the filter sponge 6, the fluid enters the air outlet pipe 22 through the main body 4.

[0046] As shown in Figure 10 , the frame 5 has a bottom wall 51 and four side walls 52 surrounding the filter sponge 6, one of which is an active wall 53 movably connected to the frame 5. The active wall 53 can move between a first position and a second position, and the active wall 53 is provided with a trigger 7 linked thereto, and the main body 4 is provided with a sensor 8 matched with the trigger 7; when the filter sponge 6 is installed between the four side walls 52 of the frame 5, the filter sponge 6 tightly presses the active wall 53 to position the active wall 53 at the second position (see Figure 12 , Figure 8 ), so that the trigger 7 triggers the sensor 8, and when the filter sponge 6 is not installed, the active wall 53 moves to the first position, so that the trigger 7 cannot trigger the sensor 8. The sensor 8 is connected to the control system of the device to detect whether the filter sponge 6 is installed by the position of the active wall 53. When the filter sponge 6 is not installed, the device does not work to avoid burning of the heating element 31.

The rear side is hinged and fixed in cooperation with the springs 101, after a certain downward pressure is applied to the front side of the frame 5, the frame 5 can be rotated downward around the hinge shaft, so that the filter sponge 6 can be easily disassembled.

[0048] Preferably, corresponding bolts and nuts are arranged on the spring racks 100 corresponding to the two springs 101, the bolts pass through the bottom of the spring racks 100 to the upper side of the spring racks 100, the nuts are screwed on the bolts and abut against the upper end face of the spring racks 100, one end of the spring 101 is tightly sleeved on the nut, and the other end of the spring 101 is not fixed but only abuts against the clamping grooves 54 on both sides of the frame 5. The spring 101 adopts the mode that one end is fixed and the other end is free, which meets the fixing requirement of the spring 101 and does not hinder the rotating function of the frame 5.

[0049] In the embodiment, as shown in Figure 16As shown, the front side edge of the bottom wall 51 of the frame 5 is provided with a first vertical wall 511 extending vertically upward, the top edge of the first vertical wall 511 is provided with a horizontal wall 512 extending horizontally away from the frame 5, the edge of the horizontal wall 512 is provided with a second vertical wall 513 extending vertically downward, the second vertical wall 513 is provided with a transverse mounting slot 5131, the trigger 7 is arranged in the interlayer formed between the first vertical wall 511 and the second vertical wall 513, the bottom edge of the movable wall 53 extends horizontally into the interlayer to form a first horizontal end 531, the first horizontal end 531 is connected with an L-shaped first connecting piece 110, the first connecting piece 110 has a second horizontal end 111 and a vertical end 112, the second horizontal end 111 covers and is connected to the first horizontal end 531 from the outside of the second vertical wall 513 through the mounting slot 5131, the vertical end 112 is located outside the second vertical wall 513 and forms a limiting fit with the second vertical wall 513, and the vertical end 112 is arranged downward, an L-shaped second connecting piece 120 is arranged in the interlayer, the second connecting piece 120 has a third horizontal end 121 and a second vertical end 122, the third horizontal end 121 covers and is connected to the second horizontal end 111, the second vertical end 122 is arranged upward and forms a limiting fit with the inner side wall of the second vertical wall 513, and the trigger 7 is fixed to the upper surface of the third horizontal end 121. The center of gravity of the whole formed by the movable wall 53, the first connecting piece 110, the second connecting piece 120 and the trigger 7 is in the interlayer, and is clamped on the mounting slot 5131 by the vertical end 112 of the first connecting piece 110 (see Figure 13 ), to prevent the whole from falling, and in the state that the filter sponge 6 is not installed, it naturally falls downward by gravity, at this time, the position of the movable wall 53 is the first position, and the trigger 7 is away from the sensor 8.

[0050] Correspondingly, a Z-shaped push piece 130 is inserted through the second vertical wall 513 (see ​ ), one end of the push piece 130 is a three-pronged plate 131, the second horizontal end 111 of the first connecting piece 110 is provided with three avoiding holes corresponding to the three-pronged plate 131, the three-pronged plate 131 of the push piece 130 penetrates into the interlayer from the mounting slot 5131 and passes through the three avoiding holes to the lower side of the second horizontal end 111, and the other end of the push piece 130 opposite to the three-pronged plate 131 is arranged upward, and pressing the one end of the push piece 130 arranged upward can make the three-pronged plate 131 of the other end abut against the lower side of the second horizontal end 111 of the second connecting piece 120.

[0051] The pusher 130 has two functions, one is that when the upper end of the pusher 130 is pressed downward, the three-pronged plate 131 can push the second horizontal end 111 of the second connecting plate 120 downward, so that the movable wall 53, the first connecting plate 110, the second connecting plate 120 and the trigger 7 rotate around the contact line of the mounting seam 5131 until the movable wall 53 moves to the second position, that is, the movable wall 53 is perpendicular to the bottom wall 51 of the frame 5, at which time the filter sponge 6 can be smoothly clamped into the frame 5, otherwise, the movable wall 53 as one of the side walls 52 of the frame 5 does not form a vertical with the bottom wall 51, so that the filter sponge 6 cannot be smoothly installed; and the frame 5 is pressed downward to rotate the frame 5 around the hinge shaft downward, so that the filter sponge 6 can be smoothly removed, so the second function of the pusher 130 is to control the opening of the frame 5, so that the movable wall 53 moves to the second position while the frame 5 is opened by pressing the pusher 130 downward, which facilitates the installation of the filter sponge 6.
