Description

Technical Field

[0001] This utility model belongs to the field of screw conveyor extrusion technology, and specifically relates to a screw conveyor extrusion device. Background Technology

[0002] The screw conveyor dewatering equipment is a mechanical device that integrates conveying and dewatering functions. It mainly consists of a screw shaft, casing, inlet, and outlet. Its working principle is based on the rotation of the screw shaft propelling the material forward, while the squeezing action of the screw blades gradually squeezes out the moisture from the material within the extrusion space of the casing, achieving both dewatering and conveying. This equipment features a compact structure, small footprint, high conveying efficiency, and excellent dewatering effect. It can be widely used in food processing, chemical, pharmaceutical, and environmental protection industries, and is suitable for processing materials with high moisture content such as fruit and vegetable residues, medicinal residues, and sludge. It effectively reduces material volume and lowers subsequent processing costs, while ensuring the continuity and stability of material conveying. It is one of the important pieces of equipment for achieving material dewatering and efficient conveying.

[0003] Currently, the internal filter cartridges of screw conveyor extrusion equipment on the market are generally not removable. However, after long-term use, the filter cartridges are prone to residual material residues and impurities. The inability to disassemble makes it difficult to thoroughly clean them, which can breed bacteria, affect material quality, and cause safety hazards. Moreover, the characteristics of different materials, such as particle size and viscosity, have different requirements for the pore size and material of the filter cartridges. The inability to disassemble and replace the filter cartridges makes it difficult for the equipment to flexibly adapt to diverse production needs and limits its application scenarios. Utility Model Content

[0004] In response to the problems mentioned in the background art, the purpose of this utility model is to provide a screw conveyor squeezing device to solve the problems that after long-term use, the filter cylinder is prone to residual material residue and impurities, cannot be disassembled and therefore cannot be thoroughly cleaned, which will breed bacteria, affect the quality of materials, and cause safety hazards. Moreover, the characteristics of different materials, such as particle size and viscosity, have different requirements for the pore size and material of the filter cylinder. The inability to disassemble and replace the filter cylinder will make it difficult for the equipment to flexibly adapt to diverse production needs and limit its application scenarios.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A screw conveyor extrusion device includes a casing, a feed hopper fixedly connected to the outer wall of the casing, a drive motor installed at one end of the casing, the output end of the drive motor extending into the casing and fixedly connected to a screw shaft, a filter cylinder movably connected inside the casing, filter holes symmetrically opened at equal intervals on the outer wall of the filter cylinder, a mounting base fixedly connected to one end of the filter cylinder, a fixing base fixedly sleeved on the outer side of the casing, fixing components symmetrically installed on one side of the fixing base, and a drainage groove opened on the outer wall of the casing, the drainage groove communicating with the interior of the casing.

[0007] The fixed assembly includes a rotating column, a first threaded hole, a threaded rod, and a limiting block. A rotating column is symmetrically connected to one side of the fixed base via a circumferential array. One end of the rotating column has a first threaded hole that penetrates the fixed base. A threaded rod is threaded into the first threaded hole, and one end of the threaded rod is fixedly connected to the limiting block. A transmission assembly is mounted on the outside of the rotating column. An assembly block is symmetrically fixed to the outer wall of the mounting base via a ring-shaped circumferential array. A second threaded hole is opened on one side of the assembly block, and the threaded rod is threadedly connected to the second threaded hole. The transmission assembly includes a drive gear, a driven gear, a connecting column, and a rotating ring. A driven gear is fixedly sleeved on the outside of the rotating column. A drive gear is rotatably connected to one side of the fixed base and sleeved on the machine... On the outside of the housing, the drive gear and the driven gear mesh with each other. A connecting column is symmetrically fixed to one side of the drive gear via a ring array. A rotating ring is rotatably connected to the outside of the housing. The other end of the connecting column is fixedly connected to the rotating ring. This allows for quick installation and disassembly of the filter cartridge without the need for complex tools or professional personnel, significantly reducing maintenance time. After disassembly, the filter cartridge can be thoroughly cleaned to remove residual materials and impurities, ensuring material quality and safety. Furthermore, when the filter cartridge becomes clogged, worn, or damaged, it can be quickly disassembled and replaced with a simple rotation operation, without the need for complete disassembly of the equipment. This significantly reduces downtime, minimizes the impact of equipment failure on production efficiency, simplifies the maintenance process, and lowers maintenance costs.

[0008] As a preferred technical solution, a sliding ring is slidably fitted on the outer side of the casing along the axial direction. One side of the sliding ring is fixedly connected to a limiting post through a symmetrical circumferential array, and the other side of the rotating ring is provided with a limiting hole through a symmetrical circular circumferential array. The limiting post and the limiting hole are inserted into each other, which can effectively limit the autonomous rotation of the rotating ring in the non-operating state, prevent the rotating ring from shifting due to vibration and other factors during equipment operation, avoid loosening of the threaded rod of the filter cylinder, ensure the fixed position of the filter cylinder during the squeezing process, and maintain the safety and reliability of equipment operation.

[0009] As a preferred technical solution, guide grooves are symmetrically opened on the outer wall of the housing, and guide blocks are symmetrically fixedly connected to the inner wall of the sliding ring. The guide blocks and guide grooves are slidably connected, and the guide blocks slide within the guide grooves, providing a clear circumferential movement trajectory for the sliding ring and strictly limiting its radial displacement.

[0010] As a preferred technical solution, a base is symmetrically fixedly connected to the outer side of the casing, and a support leg is fixedly connected to the outer side of each base. Anti-slip pads are glued to the bottom of the support legs. The surface of the anti-slip pads is provided with anti-slip texture. The anti-slip pads are made of soft rubber, which can increase the friction with the ground and effectively prevent the equipment from shifting due to vibration or external force during operation. It is especially suitable for working environments with high humidity, smoothness or vibration.

[0011] In summary, the present invention has the following main advantages:

[0012] In this invention, the filter cartridge is inserted into the housing, merging the mounting base with one end of the housing. Rotating the rotating ring drives the drive gear via the connecting column, which in turn drives the driven gear, which in turn drives the rotating column. Simultaneously, the first threaded hole and the threaded rod engage in threaded transmission, controlling the threaded rod's forward movement. The threaded rod then connects to the second threaded hole on the outer mounting block of the mounting base, completing the filter cartridge installation. This allows for quick installation and removal of the filter cartridge without the need for complex tools or professional personnel, significantly reducing maintenance time. After disassembly, the filter cartridge can be thoroughly cleaned to remove residual materials and impurities, ensuring material quality and safety. Furthermore, when the filter cartridge becomes clogged, worn, or damaged, it can be quickly disassembled and replaced with a simple rotation operation, eliminating the need for complete equipment disassembly. This significantly reduces downtime, minimizes the impact of equipment failure on production efficiency, simplifies the maintenance process, and lowers maintenance costs. Attached Figure Description

[0022] The fixing component 14 includes a rotating column 141, a first threaded hole 142, a threaded rod 143, and a limiting block 144. The rotating column 141 is symmetrically rotatably connected to one side of the fixing base 13 via a circumferential array. The first threaded hole 142 is opened at one end of the rotating column 141 and passes through the fixing base 13. The threaded rod 143 is threadedly connected inside the first threaded hole 142. The limiting block 144 is fixedly connected to one end of the threaded rod 143. A transmission component 16 is installed on the outside of the rotating column 141. An assembly block 12 is symmetrically fixedly connected to the outer wall of the mounting base 11 via a ring-shaped circumferential array. A second threaded hole 15 is opened on one side of the assembly block 12. The threaded rod 143 is threadedly connected to the second threaded hole 15. When the rotating column 141 is controlled to rotate by the transmission component 16, the first threaded hole 142 and the threaded rod 143 are simultaneously threadedly driven, thereby controlling the threaded rod 143 to move forward. The threaded rod 143 is threadedly connected to the second threaded hole 15 on the assembly block 12 on the outside of the mounting base 11.

[0023] refer to Figure 2 , Figure 4The transmission assembly 16 includes a drive gear 161, a driven gear 162, a connecting column 163, and a rotating ring 164. The driven gear 162 is fixedly sleeved on the outside of the rotating column 141. The drive gear 161 is rotatably connected to one side of the fixed base 13. The drive gear 161 is sleeved on the outside of the housing 1. The drive gear 161 and the driven gear 162 mesh with each other. The connecting column 163 is symmetrically fixedly connected to one side of the drive gear 161 through an annular circumferential array. The rotating ring 164 is rotatably connected to the outside of the housing 1. The other end of the connecting column 163 is fixedly connected to the rotating ring 164.

One side of the rotating ring 164 is provided with a limiting hole 21 by a symmetrical circular array. The limiting post 20 and the limiting hole 21 are inserted into each other. Pushing the sliding ring 17 causes the sliding ring 17 to slide on the outer side of the housing 1. At the same time, the sliding ring 17 drives the limiting post 20 to be inserted into the limiting hole 21 on the side of the rotating ring 164.

[0025] refer to Figure 5 The outer side wall of the housing 1 is symmetrically provided with guide grooves 19, and the inner wall of the sliding ring 17 is symmetrically fixed with guide blocks 18.

Anti-slip pads 8 are glued to the bottom of the support legs 7. The surface of the anti-slip pads 8 is provided with anti-slip texture. The anti-slip pads 8 are made of soft rubber. The support legs 7 form a stable support structure, which can evenly distribute the weight of the equipment and avoid shaking or tilting due to the shift of the center of gravity, thus ensuring the stability of the equipment during operation. The anti-slip pads 8 can increase the friction with the ground and effectively prevent the equipment from shifting due to vibration or external force during operation. It is especially suitable for working environments with moisture, smoothness or large vibration.

[0027] Operating principle and advantages: First, insert the filter cylinder 9 into the housing 1, so that the mounting base 11 is joined to one end of the housing 1. Rotate the rotating ring 164, which drives the drive gear 161 to rotate through the connecting column 163. The drive gear 161 drives the driven gear 162 to rotate, and the driven gear 162 drives the rotating column 141 to rotate. At the same time, the first threaded hole 142 and the threaded rod 143 are threadedly driven, thereby controlling the threaded rod 143 to move forward. The threaded rod 143 is threadedly connected to the second threaded hole 15 on the outer mounting block 12 of the mounting base 11, thus completing the installation of the filter cylinder 9. Start the drive motor 2 and control the screw shaft 3 to rotate. Add the material into the filter cylinder 9 through the feed hopper 4. The material is conveyed and squeezed by the screw shaft 3. The moisture in the material enters the housing 1 through the filter hole 10. The moisture inside the housing 1 is discharged through the drain trough 5.

[0028] This invention allows for the rapid installation and disassembly of the filter cartridge 9 without the need for complex tools or professional personnel, significantly reducing maintenance time. After disassembly, the filter cartridge 9 can be thoroughly cleaned to remove residual materials and impurities, ensuring material quality and safety. Furthermore, when the filter cartridge 9 becomes clogged, worn, or damaged, it can be quickly disassembled and replaced with a simple rotation operation, without the need for complete equipment disassembly. This significantly reduces downtime, minimizes the impact of equipment failure on production efficiency, simplifies the maintenance process, and lowers maintenance costs.
