Description

Technical Field

[0001] This utility model relates to the technical field of waste treatment, specifically to a waste solid-liquid separation device. Background Technology

[0002] Waste refers to discarded items that have lost their value and cannot be utilized. It is an important link in the material cycle and consists of unwanted or useless solid and liquid substances. Due to the environmental pollution caused by waste, some waste incineration technologies have emerged in recent years. However, waste contains a large amount of liquid with a low calorific value. When directly mixed with waste for incineration, it affects the combustion state of the waste, lowers the flue gas temperature, and increases the production of dioxins. Therefore, before incineration, solid-liquid separation is necessary to reduce the moisture content of the waste and ensure its combustion state. Furthermore, waste, especially food waste, contains a large amount of liquid during recycling. If not treated, it will produce a large amount of foul odor during landfill. Therefore, solid-liquid separation is also required to separate the liquid and then treat it.

[0003] A solid-liquid separation device for waste, disclosed in Chinese Patent Publication No. CN211799273U, comprises an outer cylinder, an inner cylinder, and an annular base. The outer cylinder is mounted on the annular base, and the inner cylinder is installed inside the outer cylinder. A first bearing is installed between the inner cavity at the top of the outer cylinder and the outer wall at the top of the inner cylinder. The bottom of the inner cylinder is connected to a rotating shaft, which passes through the bottom of the outer cylinder and is connected to a servo motor. The servo motor is mounted at the bottom of the outer cylinder and is located within the cavity of the annular base. The servo motor drives the rotating shaft to rotate the inner cylinder relative to the outer cylinder. Several through holes are provided on the side wall of the inner cylinder. A water inlet pipe is installed at the top of the outer cylinder, and a drain pipe is installed at the bottom of the outer cylinder. An annular water pipe is also installed on the inner wall at the top of the outer cylinder, and the water inlet pipe communicates with the annular water pipe. Several drain holes are provided on the annular water pipe. A water-blocking device is also installed on the inner wall of the outer cylinder, and the annular water pipe is located within the water-blocking device, which prevents the water in the annular water pipe from communicating with the outer wall of the outer cylinder.

[0004] In the above solution, the inner cylinder is connected to the inside of the outer cylinder through the first bearing, and the inner cylinder is rotated by the servo motor and the rotating shaft to separate the solid and liquid waste. This results in the following disadvantage: the inner cylinder cannot be removed from the outer cylinder, and it is necessary to reach into the narrow inner cylinder when removing the waste. Utility Model Content

[0005] The purpose of this invention is to provide a solid-liquid separation device for waste, so as to solve the problem that the inner cylinder cannot be removed from the outer cylinder, and thus requires reaching into the narrow inner cylinder when removing waste.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a solid-liquid separation device for waste, comprising an outer cylinder, the outer cylinder being fixed to the top surface of a base, a rotating frame being connected to the inside of the outer cylinder via bearings, an inner cylinder being detachably installed inside the rotating frame, a plurality of through holes being opened on the outer wall of the inner cylinder, fixing grooves being opened on the left and right sides of the outer wall of the inner cylinder, fixing holes being opened on the left and right sides of the outer wall of the rotating frame, fixing shafts being slidably inserted into the interior of two fixing holes, the two fixing shafts being slidably inserted into two fixing grooves, a stop block being fixed to the outer end of each of the two fixing shafts, and a spring being fixed between each of the two stop blocks and the rotating frame, the two springs being respectively wrapped around the two fixing shafts.

[0007] Preferably, a motor is fixed to the bottom surface of the outer cylinder, the output shaft of the motor passes through the outer cylinder and extends into the interior of the outer cylinder, a bearing is provided between the output shaft of the motor and the outer cylinder, a sealing gasket is provided between the output shaft of the motor and the outer cylinder, and a drain pipe is fixedly connected to the front side of the outer wall of the outer cylinder.

[0008] Preferably, positioning blocks are fixed on the front and rear sides of the outer wall of the inner cylinder, and positioning grooves are respectively opened on the front and rear sides of the inner side of the rotating frame, with the two positioning grooves respectively positioning the two positioning blocks.

[0009] Preferably, an annular plate is fixed inside the outer cylinder, an annular tube is fixed to the bottom surface of the annular plate, a water inlet pipe is fixed to the front side of the outer wall of the outer cylinder, the rear end of the water inlet pipe is fixed to the annular tube, and a plurality of nozzles are fixed to the bottom surface of the annular tube.

[0010] Preferably, the top surface of the rotating frame is bolted with a sealing cover.

[0011] Preferably, a sealing ring is fixed to the bottom surface of the sealing cover.

[0012] Compared with the prior art, a waste solid-liquid separation device adopting the above technical solution has the following advantages:

[0013] Beneficial effects:

[0014] 1. In use, the outer cylinder, base, rotating frame, inner cylinder, through hole, fixing groove, fixing hole, fixing shaft, stop block and spring work together to provide convenience for workers. After solid-liquid separation of garbage, the inner cylinder can be taken out, so as to easily take out the relatively dry garbage inside. This avoids the trouble of workers having to reach into the narrow inner cylinder when taking out garbage, which not only improves work efficiency, but also reduces the difficulty of operation.

[0015] Second, during use, inserting the positioning block into the positioning slot assists in positioning, ensuring that the fixing slot aligns with the fixing hole. This eliminates the need for repeated adjustments to the inner cylinder's position when inserting the fixing shaft later, improving installation convenience and accuracy. It also enables the rinsing of the outer cylinder's inner wall, improving the device's hygiene and lifespan.

[0016] Third, during use, after separation is complete, staff only need to unscrew the bolts to remove the sealing cover, facilitating subsequent waste removal and device maintenance. When the sealing cover is fixed to the rotating frame with bolts, the sealing ring is compressed and tightly fitted between the sealing cover and the rotating frame, effectively filling the tiny gaps between them and forming a reliable sealing barrier, further enhancing the device's sealing performance.

Detailed Implementation

[0022] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] like Figures 1-4As shown, a solid-liquid separation device for waste includes an outer cylinder 1, which is fixed to the top surface of a base 2. A rotating frame 3 is connected to the inside of the outer cylinder 1 via a bearing. An inner cylinder 4 is detachably installed inside the rotating frame 3. Several through holes 5 are provided on the outer wall of the inner cylinder 4. Fixing grooves 6 are provided on the left and right sides of the outer wall of the inner cylinder 4. Fixing holes 7 are provided on the left and right sides of the outer wall of the rotating frame 3. Fixing shafts 8 are slidably inserted into the two fixing holes 7. The two fixing shafts 8 are slidably inserted into the two fixing grooves 6. A stop block 9 is fixed to the outer end of each of the two fixing shafts 8. A spring 10 is fixed between each of the two stop blocks 9 and the rotating frame 3. The two springs 10 are respectively wrapped around the two fixing shafts 8. A motor 11 is fixed to the bottom surface of the outer cylinder 1. The output shaft of the motor 11 passes through the outer cylinder 1 and extends into the inner surface of the outer cylinder 1. A bearing is provided between the output shaft of the motor 11 and the outer cylinder 1. A sealing gasket 12 is provided between the output shaft of the motor 11 and the outer cylinder 1. A drain pipe 13 is fixedly connected to the front side of the outer wall of the outer cylinder 1.

[0024] In use, the staff first pours the waste to be processed into the inner cylinder 4. Then, the motor 11 is started. The output shaft of the motor 11 rotates smoothly under the support of the bearing. At the same time, the sealing gasket 12 effectively prevents liquid leakage and ensures the normal operation of the motor 11. The motor 11 drives the rotating frame 3 to rotate at high speed. Since the inner cylinder 4 is detachably installed in the rotating frame 3, the inner cylinder 4 rotates together. During the high-speed rotation, the waste in the inner cylinder 4 is subjected to centrifugal force. The liquid waste is thrown out through several through holes 5 opened on the outer wall of the inner cylinder 4 and flows slowly down the inner wall of the outer cylinder 1. Finally, it collects at the bottom of the outer cylinder 1 and is discharged from the device through the drain pipe 13, thus achieving solid-liquid separation.

[0025] After the solid-liquid separation of the waste is completed, when it is necessary to remove the relatively dry solid waste, the staff only needs to gently pull the stop block 9 outward. At this time, the spring 10 is stretched, and the fixed shaft 8 moves outward and disengages from the fixed groove 6. This operation releases the fixed relationship between the inner cylinder 4 and the rotating frame 3. The staff can then remove the inner cylinder 4 from the rotating frame 3 and conveniently and quickly pour out the relatively dry waste inside. After the waste is poured out, pull the stop block 9 outward again, and the spring 10 is stretched again. Then, put the inner cylinder 4 into the interior of the rotating frame 3, align the fixed groove 6 with the fixed hole 7, and release the stop block 9. The spring 10 will automatically reset the fixed shaft 8 by its own elasticity, allowing it to slide into the fixed groove 6, thus completing the firm fixation of the inner cylinder 4 and facilitating the next solid-liquid separation operation.

[0026] Through the coordinated action of the outer cylinder 1, base 2, rotating frame 3, inner cylinder 4, through hole 5, fixing groove 6, fixing hole 7, fixing shaft 8, stop block 9 and spring 10, convenience is provided for the staff. After the solid-liquid separation of the garbage, the inner cylinder 4 can be taken out, so that the relatively dry garbage inside can be easily taken out. This avoids the trouble of the staff having to reach into the narrow inner cylinder 4 when taking out the garbage, which not only improves the work efficiency, but also reduces the difficulty of operation.

[0027] like Figures 1-3 As shown, positioning blocks 14 are fixed on the front and rear sides of the outer wall of the inner cylinder 4, and positioning grooves 15 are respectively opened on the front and rear sides of the inner side of the rotating frame 3. The two positioning grooves 15 respectively position the two positioning blocks 14.

[0028] During use, when the staff installs the inner cylinder 4 into the inside of the rotating frame 3, the positioning block 14 is inserted into the positioning groove 15 to assist in positioning, so that the fixing groove 6 corresponds to the fixing hole 7. In this way, when the fixing shaft 8 is inserted later, there is no need to repeatedly adjust the position of the inner cylinder 4, which improves the convenience and accuracy of installation.

[0029] like Figure 1 , Figure 2 and Figure 4 As shown, an annular plate 16 is fixed inside the outer cylinder 1, an annular pipe 17 is fixed on the bottom surface of the annular plate 16, a water inlet pipe 18 is fixedly connected to the front side of the outer wall of the outer cylinder 1, the rear end of the water inlet pipe 18 is fixedly connected to the annular pipe 17, and several nozzles 19 are fixedly connected to the bottom surface of the annular pipe 17.

[0030] During use, after the solid-liquid separation of waste is completed, the staff delivers external water to the annular pipe 17 through the inlet pipe 18. The annular plate 16 provides stable support for the annular pipe 17, ensuring its stability during operation. After the external water enters the annular pipe 17, it is sprayed out through several nozzles 19 fixed to the bottom of the annular pipe 17. This water flow washes the inner wall of the outer cylinder 1, flushing off the liquid residue adhering to the inner wall. The flushed wastewater flows down the inner wall of the outer cylinder 1 and is finally discharged from the device through the drain pipe 13, realizing automated flushing of the inner wall of the outer cylinder 1 and improving the hygiene and service life of the device.

[0031] like Figures 1-3 As shown, a sealing cover 20 is bolted to the top surface of the rotating frame 3, and a sealing ring 21 is fixed to the bottom surface of the sealing cover 20.

[0032] During use, after the staff pours the waste into the inner cylinder 4, to prevent the waste from splashing out during the high-speed rotation of the rotating frame 3 and to ensure that the solid-liquid separation process takes place in a relatively closed environment, the staff securely fixes the sealing cover 20 to the rotating frame 3 with bolts. The sealing cover 20 effectively blocks the waste, preventing it from scattering outside the device due to centrifugal force, thus ensuring the cleanliness of the surrounding environment and preventing the waste from contaminating or damaging other components of the device. After separation is complete, the staff only needs to unscrew the bolts to remove the sealing cover 20, facilitating subsequent waste removal and device maintenance. When the sealing cover 20 is fixed to the rotating frame 3 with bolts, the sealing ring 21 is compressed and tightly fitted between the sealing cover 20 and the rotating frame 3, effectively filling the tiny gap between the sealing cover 20 and the rotating frame 3, forming a reliable sealing barrier, further enhancing the sealing performance of the device, ensuring that the waste will not leak from the connection between the sealing cover 20 and the rotating frame 3, ensuring the smooth progress of the separation process and the cleanliness of the surrounding environment.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
