Description

Technical Field

[0002] The screening equipment for crayfish tail processing is mainly used to sort, clean, and classify crayfish tails during processing to ensure product quality and consistency.

[0003] Existing screening equipment for crayfish tail processing faces several problems in practical applications, particularly when screening tails. The tails tend to stick together during processing, leading to unsatisfactory screening results. Specifically, crayfish secrete mucus during their growth, which is sticky. Even after washing, some mucus may remain, causing the tails to stick together. This sticking often prevents the screening mesh from effectively separating the tails, resulting in blockages or jams during screening. Existing equipment typically lacks a dedicated separation structure, preventing the screening equipment from effectively separating the sticky tails on the screen surface, thus reducing sorting efficiency and accuracy.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Example 1, please refer to Figure 1-6 This utility model provides a technical solution: a screening device for processing crayfish tails, including a device body 1. A nozzle 101 is arranged on the top side inside the device body 1. A first water pipe 102 is fixedly installed on the front side of the nozzle 101. A pump 103 is fixedly installed at the other end of the first water pipe 102. The rear side of the pump 103 is fixedly installed on the front side of the device body 1. A second water pipe 104 is fixedly installed at the bottom of the pump 103. The other end of the second water pipe 104 is fixedly installed at the bottom front side of the device body 1. A water inlet pipe 105 is fixedly installed on the front side inside the device body 1. The device body 1 also includes: a filter plate 106, fixedly embedded inside the device body 1. A cover plate 107 is movably embedded on the rear side of the device body 1 and at the top of the filter plate 106. A partition plate 118 is fixedly installed inside the device body 1. A rotating rod 108 is movably embedded on the left side of the device body 1. A reciprocating screw 109 is fixedly installed on the right side of the rotating rod 108. The reciprocating screw 109 is movably embedded inside the device body 1. A slider 110 is threadedly connected to the outer surface of the reciprocating screw 109. The slider 110 is movably embedded inside the partition 118. A scraper 111 is fixedly installed at the bottom of the slider 110. The bottom of the scraper 111 is movably connected to the top of the filter plate 106. Sliding rods 112 are slidably connected to both sides of the scraper 111. A first synchronous wheel 113 is fixedly sleeved on the outer left side of the rotating rod 108. Both sliding rods 112 are fixedly embedded inside the device body 1. A support frame 114 is fixedly installed on the left side of the device body 1. A motor 115 is installed inside the support frame 114. A second synchronous wheel 116 is fixedly sleeved on the outer surface of the output shaft of the motor 115.

[0034] In this embodiment, shrimp tails are first placed inside the sieve barrel 2, and water is injected into the device body 1 through the water inlet pipe 105. Then, the power supply system of the pump 103 is used to start the pump 103, which, during operation, can draw water from inside the device body 1 through the second water pipe 104, allowing it to enter the nozzle 101 through the first water pipe 102. The nozzle 101 then sprays clean water into the sieve barrel 2 to separate the adhering shrimp tails. The sprayed water passes through the sieve barrel 2 and the guide plate 201 and falls onto the filter plate 106, where it is filtered. Simultaneously, personnel can start the motor 115 through the power supply system of the motor 115 on the support frame 114. During operation, the motor 115 is driven by the output shaft to the second synchronous pulley 116, and the second synchronous pulley 116 is driven by the synchronous belt 117 to the first synchronous pulley 113. When the first synchronous pulley 113 rotates, it can transmit power through the output shaft to the second synchronous pulley 116. The second synchronous pulley 116 is then driven by the synchronous belt 117 to the first synchronous pulley 113. The rotating rod 108 is driven by the reciprocating screw 109. When the reciprocating screw 109 rotates, it can drive the slider 110 to slide inside the partition 118. The slider 110 drives the scraper 111 to slide left and right through the sliding rod 112 to scrape the top of the filter plate 106, preventing impurities from clogging the filter plate 106. Personnel can also open the cover 107 to clean the impurities on the top of the filter plate 106. In addition, the pump 103 spray nozzle 101 can form a circulating water flow to continuously flush the shrimp tails in the screen barrel 2. The impact force of the water flow can effectively break up the clumps of shrimp tails, avoiding screening errors caused by shrimp tail sticking together. At the same time, the scraper 111 can promptly scrape off the impurities trapped on the filter plate 106 during the filtration process, preventing the accumulation of impurities from clogging the screen holes of the filter plate 106. This allows water to pass smoothly through the filter plate 106 for recycling, maintaining the normal operation of the entire screening and separation system.

[0035] Example 2, as Figure 1-6 As shown, the outer surfaces of the second synchronous pulley 116 and the first synchronous pulley 113 are connected by a synchronous belt 117. A water outlet pipe 206 is fixedly installed at the bottom of the device body 1. A one-way valve 207 is installed inside the water outlet pipe 206. A screen barrel 2 is movably embedded inside the device body 1. The left side of the screen barrel 2 is fixedly installed on the right side of the output shaft of the motor 115. A flow guide plate 201 is installed inside the device body 1 and at the bottom of the screen barrel 2. A barrel cover 202 is movably embedded on the left side inside the screen barrel 2. Bolts 203 are threadedly connected to both sides inside the screen barrel 2. A sealing gasket 204 is provided on the outer left side of the barrel cover 202. Threaded grooves 205 are opened on both sides inside the barrel cover 202. Both bolts 203 are matched with the threaded grooves 205.

[0036] In this embodiment, after the shrimp tails are placed inside the sieve barrel 2, the operator can lift the barrel lid 202, allowing its left side to be inserted into the sieve barrel 2, and ensuring the sealing gasket 204 fits against the inner wall of the sieve barrel 2. Then, the bolt 203 is rotated to engage with the threaded groove 205, closing the sieve barrel 2. When the motor 115 is running, the output shaft drives the sieve barrel 2 to rotate, screening the shrimp tails inside. Shrimp tails meeting the standards pass through the sieve barrel 2 and are guided by the guide plate 201, causing them to roll out of the device body 1. After the shrimp tail screening is complete, the operator can open the one-way valve 207, allowing water to flow out of the device body 1 through the outlet pipe 206, and through the barrel lid 202 and the guide plate 201... The structural design allows the lid 202 to be embedded inside the sieve barrel 2, and the sealing gasket 204 to fit against the inner wall of the sieve barrel 2. This sealing structure effectively prevents water and shrimp tails from leaking from the connection between the sieve barrel 2 and the lid 202 during the screening process, ensuring that the screening work is carried out in a relatively closed environment, avoiding waste of water resources and scattering of shrimp tails. At the same time, the motor 115 drives the sieve barrel 2 to rotate through the output shaft, so that the shrimp tails are subjected to the combined action of centrifugal force and gravity inside the sieve barrel 2, which allows them to make more full contact with the wall of the sieve barrel 2, accelerating the passage of shrimp tails that meet the standards through the sieve holes of the sieve barrel 2, improving screening efficiency. In addition, the rotational motion also makes the shrimp tails roll continuously inside the sieve barrel 2, preventing the shrimp tails from piling up together, making the screening more uniform and accurate, and effectively improving the screening effect.

[0037] Working principle: In use, shrimp tails are first placed inside the sieve barrel 2, and water is injected into the device body 1 through the water inlet pipe 105. Then, the power supply system of the pump 103 is activated, allowing it to draw water from the device body 1 through the second water pipe 104 and into the nozzle 101 through the first water pipe 102. The nozzle 101 then sprays clean water into the sieve barrel 2 to separate the adhering shrimp tails. The sprayed water passes through the sieve barrel 2 and the guide plate 201, falling onto the filter plate 106 for filtration. Simultaneously, the motor 115 on the support frame 114 is activated via its power supply system. During operation, the motor 115 drives the output shaft to the second synchronous pulley 116, which in turn drives the output shaft to the first synchronous pulley 113 via the synchronous belt 117. This allows the first synchronous pulley 113 to rotate. The rotating rod 108 drives the reciprocating screw 109. When the reciprocating screw 109 rotates, it drives the slider 110 to slide inside the partition 118. The slider 110 drives the scraper 111 to slide left and right through the sliding rod 112 to scrape the top of the filter plate 106, preventing impurities from clogging the filter plate 106. Personnel can also open the cover 107 to clean the impurities on the top of the filter plate 106. In addition, the pump 103 spray nozzle 101 forms a circulating water flow to continuously flush the shrimp tails in the screen barrel 2. The impact force of the water flow effectively breaks up the clumps of shrimp tails, avoiding screening errors caused by shrimp tail sticking together. At the same time, the scraper 111 can promptly scrape off the impurities trapped on the filter plate 106 during the filtration process, preventing impurities from clogging the screen holes of the filter plate 106. This allows water to pass smoothly through the filter plate 106 for recycling, maintaining the normal operation of the entire screening and separation system.In use, after the shrimp tails are placed into the sieve barrel 2, the operator can lift the barrel lid 202, allowing its left side to fit into the sieve barrel 2, and ensuring the sealing gasket 204 fits against the inner wall of the sieve barrel 2. Then, the bolt 203 is rotated to engage with the threaded groove 205, closing the sieve barrel 2. When the motor 115 is running, it drives the sieve barrel 2 to rotate via the output shaft, screening the shrimp tails inside. Shrimp tails that meet the standards will pass through the sieve barrel 2 and be guided by the guide plate 201, causing them to roll out of the device body 1. After the shrimp tail screening is complete, the operator can open the one-way valve 207, allowing water to flow out of the device body 1 through the outlet pipe 206, and through the barrel lid 202 and guide plate 201... The structural design allows the lid 202 to be embedded inside the sieve barrel 2, and the sealing gasket 204 to fit against the inner wall of the sieve barrel 2. This sealing structure effectively prevents water and shrimp tails from leaking from the connection between the sieve barrel 2 and the lid 202 during the screening process, ensuring that the screening work is carried out in a relatively closed environment, avoiding waste of water resources and scattering of shrimp tails.

In addition, the rotational motion also makes the shrimp tails roll continuously inside the sieve barrel 2, preventing the shrimp tails from piling up together, making the screening more uniform and accurate, and effectively improving the screening effect.
