Description

Technical Field

[0001] The utility model relates to the technical field of garbage treatment, in particular to a treatment device for garbage leachate. Background Art

[0002] Garbage leachate refers to a high-concentration organic wastewater formed by the water contained in the garbage itself in the landfill, the rain and snow water entering the landfill, and other water, minus the saturated water holding capacity of the garbage and the covering soil layer, and passing through the garbage layer and the covering soil layer. In order to improve the efficiency of garbage treatment and reduce environmental pollution, garbage leachate needs to be separated and treated separately.

[0003] Current garbage leachate treatment devices usually adopt a tank structure. When separating the leachate, the garbage is loaded into the tank for operation. However, the space of the tank inlet is small, and the garbage loaded by the garbage truck is difficult to be directly sent into the tank. It needs to be dumped and then transferred separately. Not only is the efficiency low, but the increase in the transfer process also increases the risk of leachate leakage. Therefore, it is less practical. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a garbage leachate treatment device for the above-mentioned technical deficiencies, which can directly carry the garbage dumped by the garbage collection truck, improve the treatment efficiency, reduce the transportation process, and has strong practicality.

[0005] The technical scheme adopted by the utility model is: to provide a garbage leachate treatment device, comprising a load-bearing bucket arranged along the front-back direction; the front end of the load-bearing bucket is an open structure; a base is arranged below the load-bearing bucket; the load-bearing bucket is connected to the base through a supporting assembly; the bottom end of the interior of the load-bearing bucket is a wave-shaped structure from left to right; a liquid discharge port is opened along the left-right direction at the lower side of the rear end of the load-bearing bucket; a transmission pipe is fixed outside the load-bearing bucket; the transmission pipe is correspondingly connected to the liquid discharge port; a liquid extrusion mechanism and a garbage push-off mechanism are installed on the load-bearing bucket;

[0006] The liquid extrusion mechanism comprises screw rods respectively arranged on the left and right sides of the outside of the carrying bucket; the screw rods are arranged along the front-back direction; the left and right sides of the carrying bucket are respectively fixed with connecting frames; the screw rods are correspondingly rotatably connected with the connecting frames on the same side; the front end of the screw rods exceeds the front end of the carrying bucket; the screw rods are respectively controlled to rotate by a driving motor; a mounting rod is arranged between the two screw rods; the left and right sides of the mounting rods are respectively threadedly connected with the screw rods on the same side; a pressure roller is arranged below the mounting rod along the left and right directions; the left and right sides of the mounting rods are connected with connecting rods; the left and right ends of the pressure rollers are respectively rotatably connected with the connecting rods on the same side;

[0007] The garbage pushing mechanism includes a push plate that is slidably adapted to the inner wall of the carrying bucket; the push plate is arranged along the left and right directions; a plurality of liquid outlet holes are opened on the push plate; a telescope is fixed to the rear side of the outside of the carrying bucket; the telescopic end of the telescope is fixed to the push plate; the telescope is used to drive the push plate to slide correspondingly along the front and rear directions of the carrying bucket.

[0008] To further optimize the technical solution, a plurality of dredging columns arranged along the front-to-back direction are fixed to the rear end of the inner wall of the carrying bucket of the garbage leachate treatment device; the dredging columns are plugged into and correspond to the liquid outlets one by one; and the front end of the dredging columns exceeds the front end of the liquid discharge port.

[0009] To further optimize the technical solution, the support assembly of the device for treating leachate includes support columns and jacks respectively arranged on the front and rear sides of the base; the lower end of the support column is fixed to the base, and the upper end is hinged to the lower end of the carrying bucket; the lower end of the jack is hinged to the base, and the upper end is hinged to the lower end of the carrying bucket; the raising and lowering of the jack is used to control the inclination angle of the carrying bucket in the front and rear directions.

[0010] To further optimize the technical solution, the connecting rod of the garbage leachate treatment device slides vertically through the mounting rod; a compression spring is sleeved on the connecting rod; the upper end of the compression spring is connected to the mounting rod, and the lower end of the compression spring is fixed on the connecting rod.

[0011] The beneficial effects of the utility model are:

[0012] 1. The loading bucket has a large receiving area and can directly carry the garbage dumped by the garbage truck without the need for a transfer process, which reduces the risk of leakage of leachate due to transfer and improves the efficiency of garbage treatment. The drive motor drives the screw to rotate, which can drive the mounting rod to move back and forth, so that the pressure roller can roll and squeeze the garbage carried on the loading bucket, thereby improving the separation effect of the leachate.

[0013] 2. The bottom of the carrying bucket has a wavy structure from left to right, which is conducive to the leachate flowing along the trough of the wavy structure to the rear end of the carrying bucket, and can enter the transmission pipe through the drain port for discharge, thereby improving the discharge efficiency of the leachate.

[0014] 3. The push plate is slidably matched with the inner wall of the loading bucket, and the telescopic device is used to drive the push plate to slide along the front and rear directions of the loading bucket. By pushing the push plate through the telescopic device, the separated garbage in the loading bucket can be easily pushed out from the front end of the loading bucket, which can reduce garbage residue and help improve the efficiency of multiple uses.

DETAILED DESCRIPTION

[0019] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0020] like Figure 1-2 As shown, the garbage leachate treatment device comprises a carrying bucket 1 arranged along the front-back direction; the front end of the carrying bucket 1 is an open structure; a base 2 is arranged below the carrying bucket 1; the carrying bucket 1 is connected to the base 2 through a supporting assembly; the bottom end of the inside of the carrying bucket 1 is a wave-shaped structure from left to right; a liquid discharge port 3 is opened along the left-right direction at the lower side of the rear end of the carrying bucket 1; a transmission pipe 4 is fixed outside the carrying bucket 1; the transmission pipe 4 is correspondingly connected to the liquid discharge port 3; a liquid extrusion mechanism and a garbage push-off mechanism are installed on the carrying bucket 1;

[0021] like Figure 1 , Figure 3 As shown, the liquid extrusion mechanism includes screw rods 5 respectively arranged on the left and right sides of the outside of the carrying bucket 1; the screw rods 5 are arranged along the front-back direction; the left and right sides of the carrying bucket 1 are respectively fixed with connecting frames 6; the screw rods 5 are correspondingly rotatably connected with the connecting frames 6 on the same side; the front end of the screw rods 5 exceeds the front end of the carrying bucket 1; the screw rods 5 are respectively controlled to rotate by the driving motor 7; a mounting rod 8 is arranged between the two screw rods 5; the left and right sides of the mounting rod 8 are respectively threadedly connected with the screw rod 5 on the same side; a pressure roller 9 is arranged below the mounting rod 8 along the left and right directions; the left and right sides of the mounting rod 8 are connected with connecting rods 10; the left and right ends of the pressure roller 9 are respectively rotatably connected with the connecting rod 10 on the same side;

[0022] like Figure 1-2 As shown, the garbage pushing mechanism includes a push plate 11 that is slidably adapted to the inner wall of the carrying bucket 1; the push plate 11 is arranged along the left and right directions; a plurality of liquid outlet holes 12 are provided on the push plate 11; a telescopic device 13 is fixed to the rear side of the outside of the carrying bucket 1; the telescopic end of the telescopic device 13 is fixed to the push plate 11; the telescopic device 13 is used to drive the push plate 11 to slide correspondingly along the front and rear directions of the carrying bucket 1.

[0023] In this technical solution, the carrying bucket 1 has a large receiving range, and the garbage truck can directly dump the garbage into the carrying bucket 1 without dumping it elsewhere and then transferring it to the carrying bucket 1, thereby eliminating the transfer process and avoiding the problem of garbage leachate leaking to the outside due to transfer.

[0024] The transmission pipe 4 connected to the drainage port 3 at the rear end of the carrying bucket 1 is used to drain the leachate, which can be discharged into a separate collection device for centralized treatment of the leachate. In order to ensure that the leachate can be collected at the drainage port 3, the carrying bucket 1 can be appropriately tilted so that its front end is slightly higher than the rear end, and then through the bottom of the carrying bucket 1 with a wave-shaped structure, the leachate can easily flow to the rear of the carrying bucket 1 along the position of the trough; of course, during the leachate separation process, the push plate 11 is in front of the drainage port 3 to block the solid waste to prevent the solid waste from clogging the drainage port 3, and the outlet holes 12 distributed on the push plate 11 can allow the leachate to pass through and then be smoothly discharged from the transmission pipe 4.

[0025] In order to improve the separation effect of the leachate, the screw rod 5 can be driven to rotate by the driving motor 7, so that the screw rod 5 can drive the mounting rod 8 to move forward and backward (the screw rods 5 on both sides rotate synchronously to ensure the smooth movement of the mounting rod 8), so that the pressure roller 9 rolls over a certain height above the carrying bucket 1, and the garbage carried on the carrying bucket 1 is rolled and squeezed. Through the squeezing effect, the separation rate of the garbage leachate is effectively improved.

[0026] When the separation of the garbage leachate on the carrying bucket 1 is completed, the push plate 11 is driven by the telescopic device 13 to move forward along the carrying bucket 1 from the back to the front, so that the solid garbage on the carrying plate can be smoothly pushed away (after the garbage is pushed away, the push plate 11 is pulled back by the telescopic device 13), so that the carrying bucket 1 can be quickly emptied, so that the carrying bucket 1 can continue to carry out subsequent garbage leachate separation work.

[0027] like Figure 2 As shown, a plurality of dredging columns 14 arranged along the front-to-back direction are fixed to the rear end of the inner wall of the carrying bucket 1; the dredging columns 14 are plugged into and correspond to the liquid outlets 12 one by one; and the front end of the dredging columns 14 exceeds the front end of the liquid discharge port 3.

[0028] When the push plate 11 pushes the garbage and the pressure roller 9 rolls the garbage, it is inevitable that some of the garbage will cause the liquid outlet 12 to be blocked. At this time, the push plate 11 can be controlled to be pulled back by the telescopic device 13, so that the dredging column 14 is inserted into the liquid outlet 12 to push out the garbage in the liquid outlet 12. Since the front end of the dredging column 14 exceeds the front end of the drainage port 3, the push plate 11 is pulled to a certain distance from the front end of the drainage port 3 to ensure that the dredging column 14 pushes out the garbage in the liquid outlet 12, avoiding the problem of garbage falling into the drainage port 3, and improving the reliability of use.

[0029] like Figure 3 As shown, the support assembly includes a support column 15 and a jack 16 respectively arranged on the front and rear sides of the base 2; the lower end of the support column 15 is fixed to the base 2, and the upper end is hinged to the lower end of the carrying bucket 1; the lower end of the jack 16 is hinged to the base 2, and the upper end is hinged to the lower end of the carrying bucket 1; the lifting and lowering of the jack 16 is used to control the tilt angle of the carrying bucket 1 in the front and rear directions.

[0030] By lifting and lowering the jack 16, combined with the hinged connection between the jack 16, the base 2 and the carrying bucket 1, and the hinged connection between the support column 15 and the carrying bucket 1, the front and rear tilt angle of the carrying bucket 1 can be changed, so that the front end of the carrying bucket 1 can be slightly higher when squeezing the garbage to prevent the permeate from flowing out of the front end of the carrying bucket 1, and the front end of the carrying bucket 1 can be slightly lowered when cleaning the garbage from the carrying bucket 1, so as to facilitate the sliding of the garbage and make the cleaning more thorough.

[0031] like Figure 3 As shown, the connecting rod 10 slides vertically through the mounting rod 8; a compression spring 17 is sleeved on the connecting rod 10; the upper end of the compression spring 17 is connected to the mounting rod 8, and the lower end of the compression spring 17 is fixed on the connecting rod 10.

[0032] By compressing the compression spring 17 , the height of the pressure roller 9 from the carrying bucket 1 can vary to a certain extent, thereby improving the adaptability to the amount of garbage on the carrying bucket 1 .
