Description

Technical Field

[0001] This utility model belongs to the field of sorting equipment technology, and specifically relates to a coarse water washing machine. Background Technology

[0002] In waste sorting equipment, existing coarse sorting washing machines mostly use a geared motor to drive a spiral drum to rotate. The spiral drum is set at an angle, and liquid is injected into it during rotation to separate fine impurities from larger impurities. Then, the two flow out through different outlets, ultimately achieving sorting.

[0003] The aforementioned sorting equipment has several technical problems during the sorting process, primarily: Firstly, dust and fine particles from the waste adhere to the bottom of the diversion inlet and diversion chamber during free flow, accumulating over time and reducing sorting efficiency. Secondly, existing sorting machines typically pour material directly into the machine, leading to accumulation at the inlet and requiring external force to assist the material flow, further impacting sorting efficiency. Thirdly, while existing water supply pipes are located above the sorting screen, allowing direct liquid impact on the sorted items, this design prevents the bottom surface of the screen from being directly impacted. Prolonged contact between the bottom and material makes it prone to clogging by fine impurities, affecting screening efficiency.

[0004] As someone skilled in the art, summarizing the technical problems described above, it is essential to improve the sorting equipment by adopting a new structure based on the existing design, thereby overcoming the shortcomings of the existing technology described above through the new structure. Summary of the Invention

[0005] In view of the shortcomings of the prior art described above, this utility model proposes a coarse water washing machine, which can separate the material sorting channels by setting a sorting structure, and adds a thrust device for discharging fine impurities to avoid clogging inside the sorting equipment. At the same time, the design of the internal spray pipeline is improved to prevent the bottom surface of the material screen from being blocked.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A coarse washing machine includes a frame with support rollers for supporting the rolling motion of a drum screen. The drum screen is connected to a drive unit. A feeding bin is located on the inlet side of the drum screen, and a feeding auger is installed inside the feeding bin. A discharge bin is located at the bottom of the drum screen, and a discharge auger is installed inside the discharge bin. A screening port is located at the end of the drum screen. Discharge spiral blades are fixed on the inner wall of the drum screen. The discharge spiral blades are not flush with the inner wall; a gap is provided between them and the inner wall. This gap allows water to flow on the screen surface, which can wash the bottom surface of the material to prevent debris from getting stuck or adhering to the drum screen and becoming difficult to clean.

[0008] The upper part and the interior of the drum screen are equipped with spray pipes, and the spray pipes are equipped with several high-pressure spray heads.

[0009] The spray pipe includes a top spray pipe, which is located at the top of the inside of the drum screen. Several internal cleaning spray heads are installed above the top spray pipe to clean the materials inside the drum screen.

[0010] The top spray pipe extends above the screening port and is equipped with an end spray head at the screening port. The end spray head is equipped with an end control valve, which is used to independently control the end spray head to clean the screening port.

[0011] The spray pipe includes a side spray pipe, which is installed inside the machine compartment cover of the drum screen. Several external cleaning spray heads are provided on the side spray pipe facing the lower part of the side wall of the drum screen, and the bottom of the outer wall of the drum screen is cleaned through the external cleaning spray heads.

[0012] The discharge spiral blades are provided with several protrusions, which block and collide with the material being screened by the spiral, thereby improving the screening efficiency of the material in the spiral screen.

[0013] The aforementioned protrusions are designed with sharp blades, which can tear and cut the material when rotating in a spiral, thus improving the efficiency of material destruction.

[0014] This invention has the following beneficial effects: Through the above design, a support roller is installed on the frame to provide rolling support for the drum screen, which is connected to the drive device. A feeding hopper is provided on the feed side of the drum screen, and a feeding auger inside the hopper enables forced feeding, improving feeding efficiency. A discharge hopper is provided at the bottom of the drum screen, and a discharge auger is installed inside the discharge hopper to force the material falling into the drum screen to be discharged outwards, improving discharge efficiency. A screening port is provided at the end of the drum screen. Discharge spiral blades are fixed on the inner wall of the drum screen. The discharge spiral blades are not fitted into the interior; a gap is provided between them and the inner wall, allowing water to flow on the screen surface, which can wash the bottom of the material and prevent debris from getting stuck or adhering to the drum screen and becoming difficult to clean. This invention can avoid poor material supply and discharge after screening, improve discharge efficiency, and prevent material from clogging the drum screen. Attached Figure Description

[0020] The present invention will be further described below through embodiments, and those skilled in the art can refer to the embodiments for implementation.

[0021] As shown in the attached diagram, a coarse washing machine is used for material screening and cleaning. This equipment is used for sorting waste materials and includes a frame 1. A central crossbeam 11 is provided at the top of the frame 1, through which multiple support rollers 14 are fixed. The multiple support rollers 14 together provide rolling support for the drum screen 3. The outside of the drum screen 3 is sealed by a machine housing cover 12. A drum screen drive motor 10 is provided at the bottom of the frame 1, and the drum screen drive motor 10 and the drum screen 3 are driven to rotate by a drive belt 19.

[0022] This utility model has a feeding bin 2 on the feeding side of the drum screen 3. The top of the feeding bin 2 is provided with a feeding port 21. The feeding bin 2 is provided with a feeding auger 22 inside. The feeding auger 22 is connected to the feeding bin drive motor 20 to achieve drive. With this structure, the material received by the feeding port 21 can be squeezed and conveyed into the drum screen 3 by the feeding auger 22, thereby improving the material conveying efficiency.

[0023] The lower part of the rotary drum screen 3 is provided with a discharge bin 5, and a discharge auger 52 is provided inside the discharge bin 5. A discharge drive motor 51 is provided outside the discharge bin 5. The discharge drive motor 5 is connected to the discharge auger 52 inside to realize the discharge drive. Since the discharge bin 5 is connected to the rotary drum screen 3, it is used to discharge the relatively fine impurities screened by the rotary drum screen 3 to the outside. These fine impurities are very easy to adhere to or attach to the inner wall of the discharge bin 5. After the discharge drive of the discharge auger 52, the fine impurities can be prevented from adhering to the inner wall of the discharge bin 5, and the external discharge under pressure can be realized, effectively improving the impurity discharge efficiency.

[0024] The end of the drum screen 3 is provided with a screening port 13, which is used to discharge larger impurities after screening to the outside. In this invention, a discharge spiral blade 15 is fixed on the inner wall of the drum screen 3. The discharge spiral blade 15 is not fitted into the interior; it is supported and fixed by several support plates 17, and a gap 18 is provided between the discharge spiral blade 15 and the inner wall of the drum screen 3. This gap 18 allows water to flow on the screen surface of the drum screen 3, which can wash the bottom surface of the material and prevent debris from getting stuck or adhering to the drum screen 3 and becoming impossible to clean. This design effectively improves the material cleaning efficiency.

[0025] This invention features several protrusions on the discharge spiral blade 15. These protrusions obstruct and collide with the material being screened, thereby improving the screening efficiency within the spiral screen 3. These protrusions are designed as sharp-angled blades 16, which can tear and cut the material during spiral rotation, further enhancing the material's destructive efficiency.

[0026] The key design feature of this utility model is that spray pipes are provided on the upper part and inside the drum screen 3, and several high-pressure spray heads are provided on the spray pipes.

[0027] More specifically, the spray pipe includes a top spray pipe 41, with both ends of the top spray pipe 41 fixed on the machine compartment cover 12 and suspended inside the drum screen 3. Several internal cleaning spray heads 44 are fixed on the top spray pipe 41, and the top spray pipe 41 cleans the materials inside the drum screen through the internal cleaning spray heads 44.

[0028] Furthermore, the top spray pipe 41 extends above the screening port 13 and a terminal spray head 44 is provided at the screening port 13. A terminal control valve 43 is provided to control the terminal spray head 44 for independently controlling the cleaning of the screening port 13. The aforementioned terminal spray head 44 and terminal control valve 43 do not operate in real time; they are only turned on and operated when the screening port 13 is being cleaned.

[0029] Furthermore, the spray pipe also includes a side spray pipe 45, which is installed inside the machine compartment cover 12 outside the drum screen 3. Several external cleaning spray heads 46 are provided on the side spray pipe 45 facing the lower part of the side wall of the drum screen 3. The bottom of the outer wall of the drum screen is cleaned by the external cleaning spray heads 46. This area is prone to material accumulation, so the outer wall can be cleaned at any time.

[0030] This invention achieves forced feeding through the feeding auger 22 in the feeding bin 2, improving feeding efficiency; the lower part of the drum screen 3 is provided with a discharge bin 5, and the discharge bin 5 is provided with a discharge auger 52, which can force the material falling into the drum screen 3 to be discharged outward, improving discharge efficiency and preventing accumulation on the inner wall of the discharge bin 5; the end of the drum screen 3 is provided with a screening port 13, which can force larger impurities to be discharged to the outside; a discharge spiral blade 15 is fixed on the inner wall of the drum screen 3. The discharge spiral blade 15 is not attached to the inside, and a gap 18 is provided between it and the inner wall. Through the gap 18, water can flow on the screen surface of the drum screen 3, which can wash the bottom surface of the material to prevent debris from getting stuck or adhering to the drum screen 3 and being unable to be cleaned.

[0031] This invention can avoid poor material discharge during supply and screening, improve discharge efficiency, and prevent material from clogging the drum screen. It overcomes the shortcomings of the prior art and is an ideal coarse washing machine.
