Description

Technical Field

[0001] This application relates to the technical field of crustacean food processing, and specifically discloses a shrimp processing and cleaning device. Background Art

[0002] Shrimp is an arthropod living in water, with a delicious taste and is a common food.

[0003] After live shrimp are fished out of the water, they need to be processed through multiple processes, such as disinfection, cleaning and transportation, processing, etc. In the prior art, for the cleaning of shrimp, methods including using high-pressure water jets for rinsing and drum cleaning are available.

[0004] For the drum cleaning method, especially for a drum cleaning device with the drum placed horizontally, a rotatable main shaft coaxially installed inside the drum, and a number of rotatable auxiliary shafts circumferentially installed around the main shaft, brush rollers are installed on both the main shaft and the auxiliary shafts. During the rotation of the auxiliary shafts, the brush rollers on the auxiliary shafts can be staggered and fitted with the brush rollers on the main shaft, and at the same time, the brush rollers on the auxiliary shafts are also respectively in contact with the inner wall of the drum. After putting the shrimp into the drum, the continuously rotating brush rollers drive the shrimp to move inside the drum, and the shrimp are cleaned by the brushes on the brush rollers during the movement.

[0005] Although the above-mentioned shrimp processing and cleaning device can achieve the cleaning of shrimp, during the cleaning process of shrimp in the same batch or different batches, the water inside the drum cannot be replaced, and the water body will carry debris washed off from the shrimp. And the existing filtering structure installed in the shrimp processing and cleaning device usually only completes through the installed filter plate. During long-term use, the debris filtered out on the filter plate needs to be manually cleaned, otherwise it will cause the blockage of the filter plate and affect the cleaning effect of the shrimp. The existing shrimp processing and cleaning device does not have the function of automatically cleaning the debris filtered out on the filter plate.

[0033] A shrimp processing and cleaning device, such as an embodiment Figure 1 、Figure 2 and Figure 3 as shown in

[0034] It includes a filter cartridge 1 and support frames mounted on both sides of the filter cartridge 1. The filter cartridge 1 is horizontally installed between the support frames, and a material inlet is provided at the top of the filter cartridge 1. It also includes a main shaft 4 coaxially installed with the filter cartridge 1, four auxiliary shafts 5 circumferentially installed on the filter cartridge 1 around the axis of the main shaft 4, and a driving structure installed on the support frames. The right end of the main shaft 4 penetrates out of the filter cartridge 1, both ends of the auxiliary shaft 5 penetrate through the filter cartridge 1, and brush rollers are coaxially and fixedly installed on both the main shaft 4 and the auxiliary shaft 5. In this embodiment, the brush roller installed on the main shaft 4 is the first brush roller, and the brush roller installed on the auxiliary shaft 5 is the second brush roller 6. The driving structure includes a support installed on the right support frame, a driving motor fixedly installed on the support, and a belt transmission mechanism installed between the output shaft of the main shaft 4 and the driving motor.

[0035] A reverse transmission mechanism is also installed between the main shaft 4 and all the auxiliary shafts 5. Through the reverse transmission mechanism, when the main shaft 4 rotates clockwise, all the auxiliary shafts 5 can be simultaneously driven to rotate synchronously in the reverse direction. The reverse transmission mechanism includes a driving gear coaxially and fixedly installed on the main shaft 4 and driven gears respectively connected to the auxiliary shafts 5 through splines. The driven gears are all meshed with the driving gear.

[0036] A sleeve 9 is fixedly installed on the end face of the filter cartridge 1 at both ends of the auxiliary shaft 5. A round hole communicating the inner chamber of the sleeve 9 with the inner chamber of the filter cartridge 1 is provided on the filter cartridge 1. Both ends of the auxiliary shaft 5 respectively pass through the sleeve 9. In this embodiment, the reverse transmission mechanism is installed on the right side of the sleeve 9 at the right end of the filter cartridge 1, and a T-shaped ring platform is integrally formed on the inner side of the driven gear. A T-shaped ring groove for the T-shaped ring platform to slide in is provided on the right end face of the sleeve 9 to limit the driven gear.

[0037] A pressing plate 8 is also fixedly installed on the main shaft 4 on the right side of the reverse transmission mechanism. Through the pressing plate 8 rotating with the main shaft 4, the auxiliary shaft 5 is pressed into the sleeve 9 and the filter cartridge 1. Specifically, an inclined portion with the end inclined towards the inner side of the sleeve 9 is formed on the pressing plate 8. In this embodiment, two centrally symmetric inclined portions are formed on the pressing plate 8. As Figure 5 shown, when the pressing plate 8 rotates with the main shaft 4, two diagonal auxiliary shafts 5 are respectively pressed into the sleeve 9 and the filter cartridge 1 through the inclined portions on both sides.

[0038] In this embodiment, the length of the second brush roller 6 installed on the auxiliary shaft 5 is greater than the distance between the inner ends of the two sleeves 9 at both ends and less than the distance between the outer ends of the two sleeves 9 at both ends, and a gap for squeezing the brush and not allowing shrimps to enter is formed between the outer wall of the second brush roller 6 and the inner wall of the sleeve 9.

[0039] A connecting box 3 is also installed at the bottom of the filter cartridge 1, and a water inlet box 2 is also installed at the left end of the filter cartridge 1. The top surface of the connecting box 3 is tightly fitted with the bottom of the filter cartridge 1 and the bottom of the water inlet box 2. A plurality of first filter slots are provided between the filter cartridge 1 and the connecting box 3, and the size of the first filter slots is smaller than the minimum compliant size of the shrimp. The minimum compliant size here is the minimum size of the shrimp that meets the production standards set for production and processing. A water inlet is provided between the water inlet box 2 and the connecting box 3. In this embodiment, an aeration pipe 7 is also installed in the connecting box 3 below the water inlet, and an aerator connected to the aeration pipe 7 is installed outside the connecting pipe box.

[0040] like Figure 4 As shown, four water inlet pipes are installed in the water inlet box 2. The water inlet pipes have the same diameter as the sleeve 9, and the left end of the water inlet pipe is fixed on the inner wall of the water inlet box 2, and the right end of the water inlet pipe is fixedly sealed and connected to the end of the sleeve 9. In this embodiment, the left end of the secondary shaft 5 passes through the sleeve 9 and extends into the water inlet pipe, and a partition is also installed in the water inlet pipe. The partition separates the internal chamber of the water inlet pipe, and the left end of the rotating shaft is located on the right side of the partition. A plurality of second filter slots 12 are also opened on the top of the water inlet pipe on the right side of the partition. A relatively rotatable toggle mechanism is installed at the end of the secondary shaft 5. The toggle mechanism includes a toggle plate and a plurality of toggle blocks 13 integrally formed on the toggle plate and extending into the second filter slot 12. A coupling hole for the secondary shaft 5 to pass through is opened on the toggle plate, and a circle of T-shaped rings are formed. The end of the secondary shaft 5 passes through the coupling hole and a T-shaped ring groove is opened for the T-shaped ring to slide inside. The shape of the shift block 13 is the same as that of the second filter tank 12, both of which are trapezoidal with the end surface size gradually decreasing toward the inner side of the water inlet pipe. A return spring 10 is also fixedly mounted on the right end surface of the partition, and the right end of the return spring 10 abuts against the left end of the secondary shaft 5.

[0041] like Figure 4 As shown, four water inlet grooves are formed on the secondary shaft 5 in the water inlet pipe. At the same time, a plurality of water outlet holes 15 are formed circumferentially on the secondary shaft 5 and pass through the brush roller 26. A through groove 16 is formed coaxially in the secondary shaft 5 and communicates with the water inlet groove and supplies water to the water outlet hole 15. A plurality of fan blades 17 for introducing water flow into the water inlet groove are coaxially fixedly mounted on the secondary shaft 5. Moreover, the toggle mechanism, the fan blades 17, and the water inlet groove are sequentially arranged on the secondary shaft 5 along the direction in which the water flow flows into the through groove 16.

[0042] In this embodiment, a slag discharge groove is also opened at the top of the water inlet pipe on the left side of the partition, and the slag discharge groove is connected to all the second filter tanks 12, and the length of the shift block 13 is greater than the thickness of the shift plate. The shift block 13 can be used to shift the fine debris filtered out of the second filter tank 12 into the slag discharge groove for collection.

[0043] Further, an arc-shaped sealing plate 14 for closing the slag discharge tank is also installed in the water inlet pipe. The outer wall of the arc-shaped sealing plate 14 completely fits the inner wall of the water inlet pipe, and limiting blocks are formed at both ends of the arc-shaped sealing plate 14. Limiting grooves for the limiting blocks to slide in are formed on the inner side of the water inlet pipe and the partition wall surface to prevent the arc-shaped sealing plate 14 from detaching. An ejecting mechanism for ejecting the arc-shaped plate out of the slag discharge tank is also installed in the water inlet pipe. The ejecting mechanism includes an arc-shaped ejecting rod installed in the water inlet pipe and fixedly connected to the end face of the arc-shaped sealing plate 14, an ejecting platform integrally formed in the water inlet pipe, and an ejecting spring fixedly installed between the ejecting platform and the arc-shaped ejecting rod. As Figure 4 shown in the cross-sectional view, since the arc-shaped ejecting rod is fixed to the front end face of the arc-shaped sealing plate 14, the arc-shaped ejecting rod, the ejecting platform, and the ejecting spring are not shown in the figure.

[0044] A through hole is also coaxially formed on the partition plate. A control mechanism for pulling the arc-shaped sealing plate 14 to close the slag discharge tank when the secondary shaft 5 resets is installed at the end of the secondary shaft 5 and passes through the through hole. The control mechanism includes a telescopic sleeve and a pull rope 18 passing through the through hole. One end of the telescopic sleeve protrudes outward to form a limiting ring platform. A limiting ring groove for the end of the telescopic sleeve with the limiting ring platform to extend into is formed at the left end of the rotating shaft. The other end of the telescopic sleeve is fixed to the partition plate. The right end of the pull rope 18 is fixed inside the telescopic sleeve and moves synchronously with the telescopic sleeve. The other end of the pull rope 18 is fixedly installed on the end face of the arc-shaped sealing plate 14, and this end face is the front end face of the arc-shaped sealing plate 14.

[0045] When the present invention is in use, water is first filled into the filter cartridge 1, the communication box 3, and the water inlet tank 2, and then the drive motor is started to drive the main shaft 4 to rotate through the drive motor;

[0046] The rotation of the main shaft 4 will drive all the secondary shafts 5 to rotate synchronously through the reverse transmission mechanism, and the rotation direction of the secondary shaft 5 is opposite to that of the main shaft 4. During the rotation of the main shaft 4, the rotating shaft can also be intermittently pushed into the sleeve 9 and the filter cartridge 1 through the pressing plate 8;

[0047] The rotation of the secondary shaft 5 can drive the fan blades 17 to rotate synchronously, introduce water flow into the water inlet groove, the through groove 16, and the water outlet holes 15, and finally spray out through the water outlet holes 15 to realize the circulating flow of the water body. The lateral sliding of the secondary shaft 5 can drive the dial plate and the dial block 13 to move synchronously. When the dial block 13 moves to the left, the telescopic sleeve contracts, and the pull rope 18 enters the water inlet pipe on the left side of the partition plate, and the arc-shaped sealing plate 14 is pushed out of the slag discharge tank by the ejecting spring to open the slag discharge tank; when the dial plate moves to the right, the arc-shaped sealing plate 14 closes the slag discharge tank;

[0048] Then live shrimps are put in, specifically live shrimps;

[0049] The shrimps enter the filter cartridge 1 through the material opening, and are cleaned by the staggered brush rollers one and brush rollers two 6 on the main shaft 4 and the secondary shaft 5, and the shrimps are driven to stir and move in the filter cartridge 1 by the brushes of the brush rollers one and brush rollers two 6;

[0050] Moreover, as Figure 5 shown, not only can relative rotation occur between the auxiliary shaft 5 and the main shaft 4, but also transverse staggered sliding can occur. It can not only brush the shrimp shell perpendicular to the rotation direction through the brush, but also brush the shrimp shell parallel to the rotation direction, making the cleaning of the shrimp more complete. At the same time, the water flow sprayed out from the water outlet hole 15 can also wash the shrimp shell;

[0051] At the same time, the sundries brushed off will enter the communication box 3 through the first filter tank, and the sewage will also flow into the communication box 3, and the sewage is treated by the aeration method through the aeration pipe 7;

[0052] When the auxiliary shaft 5 drives the fan blade 17 to rotate synchronously, the filtered water body will enter the water inlet tank through the first filter tank. Fine sundries are filtered out through the first filter tank, and the filtered fine sundries are pushed into the opened slag discharge tank by the moving leftward block 13, and finally collected in the water inlet pipe, and the fine sundries are isolated by the arc-shaped sealing plate 14. At the same time, large-sized sundries are stored at the bottom of the communication box 3, specifically at the bottom of the communication box 3 below the first filter tank;

[0053] After the shrimp are cleaned, an external basket can be placed at the material port, and the basket opening can be extended into the filter cylinder 1 to collect the shrimp during the stirring process of the shrimp.

[0054] The above is only a preferred embodiment of the present invention, and does not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content within the scope of the technical solution of the present invention to make equivalent embodiments of equivalent changes. However, as long as it does not depart from the content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiment according to the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
