In this utility model, a base plate, a receiving hopper, a square-to-round hopper, a horizontal pipe, a vertical pipe, a first auger, a second auger, a movable sleeve, and an electric telescopic rod are provided. After the receiving hopper catches the waste, the waste enters the horizontal pipe, and then the first auger inside the horizontal pipe transports the waste to the vertical pipe. The second auger inside the vertical pipe then transports the waste upward, allowing the fertilizer to be lifted to a certain height, thus facilitating loading. Furthermore, the electric telescopic rod can drive the movable sleeve to move up and down along the surface of the receiving hopper to adapt to filter presses of different heights, improving the versatility of the device.

Description

Technical Field

[0001] This utility model relates to the field of waste recycling technology for filter presses, and in particular to a waste recycling device for filter presses. Background Technology

[0002] After the filter press produces sludge cake, a recovery device is used to collect the cake to achieve automated, efficient, and hygienic sludge treatment. When the filter press discharges, a scraper or vibrating device peels the sludge cake off the filter cloth, and the recovery device collects the fallen sludge cake waste. This device reduces manual intervention, improves processing efficiency, and prevents sludge cake from scattering and polluting the environment. It is suitable for continuous, large-scale sludge dewatering operations.

[0003] A search revealed that patent CN219251770U discloses a waste recycling device for filter presses. By setting up a receiving shell, opening plate, drive motor, threaded rod, slide plate, slide rail, slider, and rotating shaft, it is convenient to collect waste into one piece for loading, convenient to control the opening size of the two opening plates, and convenient to adjust for better waste recycling and transportation.

[0004] However, the above-mentioned device has the following drawbacks: Firstly, the height of the receiving shell is fixed, and after placing the device at the bottom of the filter press, the discharge height of the inclined receiving shell is even lower, making direct loading inconvenient and causing subsequent loading difficulties. Secondly, because the receiving shell height is fixed, it cannot adapt to filter presses with different bottom discharge outlet heights. If the height difference between the bottom discharge outlet of the filter press and the receiving shell is too large, the waste material is prone to falling outside the receiving shell. Therefore, further improvement is needed. To this end, we propose a waste material recovery device for filter presses. Utility Model Content

A square-to-round hopper 3 is fixedly disposed at the bottom of the receiving hopper 2, a discharge pipe 4 is fixedly disposed at the bottom end of the square-to-round hopper 3, and a horizontal pipe 5 is fixedly disposed at the bottom end of the discharge pipe 4. A vertical pipe 6 is fixedly connected to the end of the horizontal pipe 5 away from the receiving hopper 2. A first auger 7 and a second auger 8 are rotatably connected inside the horizontal pipe 5 and the vertical pipe 6, respectively. A movable sleeve 12 is slidably connected to the surface of the receiving hopper 2. Electric telescopic rods 13 for driving the movable sleeve 12 to move up and down are installed on both sides of the upper surface of the base plate 1. A chopping component 14 is fixedly installed at the top of the movable sleeve 12. A controller 15 is installed on the upper surface of the base plate 1.

[0023] In this embodiment, the controller 15 is a screen controller: the model is Siemens SIMATIC KP1200 series (HMI+PLC integrated machine), specifically model: KP1212 Basic PN (6AV2123-2GB03-0AX0), and the controller 15 controls the operation of various components of the device.

[0024] Multiple casters 16 are installed on the lower surface of the base plate 1.

[0025] The device can be moved easily using the casters 16.

[0026] The first motor 9 is fixedly connected to the end of the horizontal pipe 5 away from the vertical pipe 6. The first auger 7 is fixedly connected to the output end of the first motor 9. The second motor 10 is fixedly connected to the top of the vertical pipe 6. The top of the second auger 8 is fixedly connected to the output end of the second motor 10. Both the first motor 9 and the second motor 10 are electrically connected to the controller 15.

[0027] The first motor 9 drives the first auger 7 to rotate, and the first auger 7 pushes the waste material entering the horizontal pipe 5 into the vertical pipe 6. The second motor 10 drives the second auger 8 to rotate, and the second auger 8 can transport the waste material entering the vertical pipe 6 upward.

[0028] The top side wall of the vertical pipe 6 is provided with an outlet 11.

[0029] After the waste is conveyed upward along the vertical pipe 6, it will be discharged from the outlet 11. This method can lift the waste to a certain height. At this time, the vehicle is moved below the outlet 11 to catch the collected waste.

[0030] Side plates are fixed to both sides of the bottom of the movable sleeve 12. The top telescopic ends of the two electric telescopic rods 13 are fixedly connected to the two side plates respectively. The electric telescopic rods 13 are electrically connected to the controller 15.

[0031] The controller 15 can control the moving sleeve 12 to move up and down along the receiving hopper 2.
