Description

Technical Field

[0001] This utility model relates to the technical field of collagen raw material cleaning equipment, specifically to a multi-stage cleaning and screening integrated machine for collagen raw materials. Background Technology

[0002] Type I collagen is typically extracted from pig or cow skin, Achilles tendons, and other tissues. During collagen extraction, animal tissues, as raw materials, require multiple pretreatment steps to remove impurities. Each pretreatment step involves washing to remove pretreatment reagents, and screening to select particles that meet size requirements before subsequent enzymatic purification. Pretreatment is a crucial step, as its effectiveness directly impacts the quality of the final product and production efficiency.

[0003] Traditional collagen raw material pretreatment processes typically employ separate equipment, meaning that the washing and screening processes are completed by independent equipment.

[0004] In practical applications, this traditional processing method has revealed many obvious shortcomings:

[0005] Raw materials must first be cleaned in cleaning equipment before being manually transported to screening equipment for sieving. This process not only consumes a lot of manpower but also prolongs the processing cycle due to multiple transfers, seriously affecting overall production efficiency. Secondly, traditional cleaning equipment often uses a single cleaning method, such as simple water rinsing, which is difficult to effectively remove impurities such as mud, bloodstains, and hair attached to the surface of the raw materials. This problem is particularly prominent for raw materials with complex structures or uneven surfaces, resulting in the raw material cleanliness failing to meet high-standard production requirements. Furthermore, most existing screening equipment uses a single-layer screen design, which can only achieve single-size screening and cannot grade the raw materials. This makes it impossible to effectively separate particles of different sizes in the raw materials, affecting the consistency of subsequent processing and potentially causing some qualified raw materials to be rejected as impurities, resulting in resource waste. Since the cleaning and screening processes are independent, the raw materials inevitably come into contact with the external environment during transportation, increasing the risk of contamination. In addition, the layout of split equipment is often relatively dispersed, making it difficult to clean between equipment. Residual impurities can easily cause cross-contamination in subsequent production, seriously affecting product quality and safety.

[0006] Therefore, based on this, the technical solution of this utility model is proposed. Utility Model Content

[0009] (II) Technical Solution

[0010] To achieve the aforementioned advantages of integration, efficiency, and precision, the specific technical solution adopted by this utility model is as follows:

A spring is sleeved on the locking rod. One end of the spring is connected to the support plate and the other end is connected to the pull block. A maintenance plate is provided on the surface of the box at the position corresponding to the vibrating box.

[0016] Both the high-pressure spray pipe and the pre-rinse pipe are connected to the water pump below the tank.

[0017] A telescopic hose is fixedly installed on the surface of the vibration box, and one end of the telescopic hose extends to the outside of the box.

[0018] The vibrating screen is used in conjunction with the vibrating box.

[0019] A sealing ring is provided between the vibrating screen and the vibrating box.

The interior is divided into a pre-rinsing zone, a high-pressure spray zone, and a screening zone according to the processing flow, realizing integrated cleaning and screening operations. The pre-rinsing zone is equipped with a first conveyor 3 (such as a chain conveyor or mesh belt conveyor), which can drive the raw material to move at a uniform speed. The upper pre-rinsing pipe 4 has an array of spray holes, which initially rinse the loose impurities (such as mud, sand, and dust) on the surface of the raw material through low-pressure water flow. The high-pressure spray zone is equipped with a second conveyor 6 (connected to the first conveyor 3, and the transmission speed can be adjusted synchronously). The upper high-pressure spray pipe 5 adopts a fan-shaped spray pattern. The nozzle, when connected to the water pump 7, can generate a 5-10MPa high-pressure water flow to impact and clean stubborn impurities such as bloodstains and hair. The screening section has a built-in vibrating box 8, which is equipped with no less than two layers of vibrating screens 10 (the screen material is 304 stainless steel, and the aperture is 5mm, 3mm, 1mm, etc. from top to bottom). The raw materials are graded and screened by a vibrating motor. The working process is as follows: the raw material enters from the feed port 2 → the first conveyor 3 drives the raw material through the pre-rinsing pipe 4 to complete the initial rinsing → the second conveyor 6 sends the raw material into the high-pressure spray zone for deep cleaning → the cleaned raw material enters the vibrating box 8 and is graded by particle size on the multi-layer vibrating screen 10. The qualified raw material is output from the screen surface, and the impurities fall from the screen holes.

[0040] Example 2

[0041] refer to Figure 1 , Figure 2 and Figure 3The vibrating screen 10 has a support plate 11 at its bottom, and a locking hole 12 on the vibrating box 8. A locking rod 13 is correspondingly provided on the side wall of the support plate 11. One end of the locking rod 13 passes through the surface of the support plate 11 and is inserted into the locking hole 12. A pull block 14 is installed on the other end of the locking rod 13. A spring 15 is sleeved on the locking rod 13. One end of the spring 15 is connected to the support plate 11, and the other end is connected to the pull block 14. A maintenance plate 16 is provided on the surface of the box 1 at the position corresponding to the vibrating box 8. The support plate 11 is fixed to the bottom of the vibrating screen 10 to provide load-bearing support. It is made of Q235B steel plate with a thickness ≥10mm to ensure structural stability during vibration. The locking hole 12 is opened on the side wall of the vibrating box 8 (diameter φ12mm). 13 is a cylindrical pin structure (diameter φ10mm), one end is machined with external threads to connect with pull block 14, and the other end is a conical head for easy insertion into locking hole 12; spring 15 is a compression spring (diameter φ8mm, free length 50mm), sleeved on locking rod 13, normally pushing locking rod 13 to keep it in the locked state inserted into locking hole 12; inspection plate 16 is installed on the box body 1 at the position corresponding to vibrating box 8, and is connected by hinge. When opened, it can expose vibrating box 8 for easy maintenance operation; disassembly and maintenance operation: pull pull block 14 → compress spring 15 → pull locking rod 13 out of locking hole 12 → release vibrating screen 10 → take out vibrating screen 10 through inspection plate 16 for cleaning or replacement → reverse operation during installation, spring 15 resets and locks.

[0042] Example 3

[0043] refer to Figure 1 Both the high-pressure spray pipe 5 and the pre-rinse pipe 4 are connected to the water pump 7 below the tank 1. The water pump 7 is a centrifugal pump (flow rate 30-50 m³ / h). 3 / h, head ≥30m), installed in an independent pump compartment below housing 1, connected to the pipeline via flange, the main pipeline is led out from pump 7 and branched into two: one connects to pre-flushing pipe 4 (diameter DN25), the water pressure is controlled at 0.2-0.3MPa through a pressure reducing valve; the other connects to high-pressure spray pipe 5 (diameter DN20), directly outputting high-pressure water flow. A Y-type filter (filtration accuracy 50 mesh) can be installed at the front end of the main pipeline to prevent impurities in the water from clogging the nozzles. A foot valve is installed at the inlet of pump 7 to ensure continuous water supply.

[0044] Example 4

[0045] refer to Figure 1 , Figure 2 and Figure 4A telescopic hose 9 is fixedly installed on the surface of the vibrating box 8, with one end of the telescopic hose 9 extending to the outside of the box body 1. The telescopic hose 9 is made of wear-resistant PVC steel wire hose (inner diameter φ100mm). One end is fixed to the discharge port on the vibrating box 8, and the other end extends to the receiving collection bucket outside the box body 1. The hose can extend and retract with the slight vibration of the vibrating box 8 to avoid breakage of the rigid connection. The impurities screened by the vibrating screen 10 fall into the bottom of the vibrating box 8 through the screen holes and are discharged through the discharge port by the telescopic hose 9. A butterfly valve can be installed at the end of the hose to facilitate control of the discharge frequency. A rubber sealing ring (section diameter 8mm) is set at the connection between the vibrating box 8 and the box body 1 and is tightened by bolts to prevent dust from overflowing during the screening process and ensure a clean workshop environment.

[0046] Example 5

[0047] refer to Figure 2 The vibrating screen 10 is used in conjunction with the vibrating box 8. Two vibrating motors (power 0.5-1kW, speed 1400r / min) are symmetrically installed on the outside of the vibrating box 8. The vibration force is generated by the rotation of the eccentric block, which drives the vibrating box 8 and the vibrating screen 10 inside to perform reciprocating linear vibration. The amplitude of the eccentric block of the vibrating motor can be adjusted by adding or removing counterweights (usually set to 2-4mm) to adjust the screening effect according to different raw material characteristics (such as particle hardness and moisture content). The screen surface inclination angle of the vibrating screen 10 is set to 5°-10°. Under the action of vibration, the raw material slides down the screen surface. Fine particles fall through the screen holes, and coarse particles are discharged from the end of the screen surface. The screening efficiency can reach more than 95%.

[0048] Example 6

[0049] refer to Figure 2 A sealing ring is provided between the vibrating screen 10 and the vibrating box 8. An annular groove is opened on the edge of the screen frame of the vibrating screen 10, and a silicone rubber sealing ring (with an L-shaped cross section) is embedded therein. When the vibrating screen 10 is installed in the vibrating box 8, the sealing ring is tightly fitted to the inner wall of the vibrating box 8 to prevent material from leaking out from the gap.

[0050] Example 7

[0051] refer to Figure 4 A control switch 17 is fixedly installed on the outer wall of the housing 1, and the control switch 17 is electrically connected to the water pump 7 through a wire. The control switch 17 (a waterproof push button switch) is installed on the operation panel on the outer wall of the housing 1 and is connected to the contactor coil of the water pump 7 through a wire to realize the start and stop control of the water pump 7. A PLC control system (optional) can be integrated to set the spraying time of the pre-rinsing pipe 4 and the high-pressure spray pipe 5 (e.g., pre-rinsing 30s, high-pressure spray 1min), and link it with the running speed of the first conveyor 3 and the second conveyor 6 to realize automated processing.

[0052] Working principle: Raw materials enter through the feed inlet 2 at the top of the housing 1. First, in the pre-rinsing zone, the first conveyor 3 drives the material past the pre-rinsing pipe 4, where low-pressure water sprays out to initially rinse loose impurities from the surface. Next, the material enters the high-pressure spray zone, where the second conveyor 6 transports it to the area below the high-pressure spray pipe 5. Under the action of the water pump 7, the high-pressure spray pipe 5 sprays high-pressure water to deeply clean stubborn impurities from the material. After cleaning, the material enters the vibrating box 8 in the screening section. The multi-layer vibrating screen 10 inside the vibrating box 8 vibrates under the drive of the vibrating motor. The material is graded according to particle size on the screen. Fine impurities fall through the screen holes and are discharged into the collection bin via the telescopic hose 9. Qualified material is output from the discharge port at the end of the vibrating screen 10 section. Throughout the process, the vibrating screen 10 is fixed or disassembled through the locking rod 13 and the locking hole 12. The control switch 17 controls the operation of the water pump 7. The sealing ring between the vibrating screen 10 and the vibrating box 8 ensures the equipment is sealed, thus completing the multi-stage cleaning and screening pretreatment of the raw materials.
