Abstract
Description
Technical Field
[0001] This utility model relates to the field of lobster processing technology, and in particular to a disinfection device for lobster processing. Background Technology
[0002] Crayfish often live in humid water, so they need to be thoroughly cleaned and disinfected before processing to remove surface dirt. Modern industrial processing of crayfish usually uses crayfish washing machines. However, existing crayfish washing machines are inefficient and often become clogged by crayfish shells and cannot work.
[0003] Chinese utility model patent CN223053793U discloses a lobster sorting device with a cleaning function, including a shell, a cleaning tank, and a screening assembly. Both the cleaning tank and the screening assembly are located inside the shell, with the screening assembly situated on the right side of the cleaning tank. A first rolling roller and a second rolling roller are rotatably connected inside the cleaning tank, with the second rolling roller located below the first rolling roller. The left side of the first rolling roller is connected to the output end of a motor. A drive wheel is disposed on the outer surface of the first rolling roller, and a driven wheel is disposed on the outer wall of the second rolling roller. The drive wheel is connected to the driven wheel via a belt. Brushes are distributed on both the first and second rolling rollers. This utility model improves the screening effect and simultaneously cleans the sorted lobsters, thereby increasing the efficiency of lobster processing.
[0004] However, its shortcomings are as follows: during the screening stage, individual crayfish are prone to getting stuck in the holes or gaps of the screening plate, which can easily cause overload of the equipment transmission mechanism and eventually lead to machine shutdown. At the same time, when using a brush to clean and scrub the crayfish in the washing tank, the mechanical scrubbing force exerts too strong an impact and friction on the crayfish shell, which can easily damage the connection structure between the shell and the muscle tissue, causing the shell and meat to separate. This results in a significant reduction in the amount of crayfish meat that can be used intact during processing, thus reducing the final yield. Utility Model Content
[0005] The purpose of this invention is to provide a disinfection device for crayfish processing, which can quickly and accurately screen large batches of crayfish raw materials by volume and perform deep and efficient cleaning of crayfish, making it suitable for industrial production lines of crayfish.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a disinfection device for lobster processing, including a frame, a feeding conveyor belt horizontally arranged at one end of the frame, a roller screening mechanism arranged at the end of the feeding conveyor belt, an inclined lifting conveyor mechanism arranged below the roller screening mechanism, a spraying mechanism, an ultrasonic cleaning tank and a discharge conveyor belt arranged sequentially at the end of the lifting conveyor mechanism along the rotation direction of the conveyor belt, a residue separation and recycling mechanism arranged below the spraying mechanism, and a conveyor belt synchronous motor arranged on the side from the spraying mechanism to the ultrasonic cleaning tank.
[0007] By adopting the above technical solution, the conveyor belt transports the lobsters into the roller screening mechanism for sorting according to their size. The sorted lobsters fall onto the lifting conveyor and are spread out evenly. The lifting conveyor then transfers them to the spraying mechanism, where large stains and dirt residues are washed off the surface. After passing through the ultrasonic cleaning tank, any remaining fine parts are washed away. The cleaned lobsters are then sent to the next process via the discharge conveyor belt. The residue separation and recycling mechanism can collect and process the separated residues. To maintain a relatively stable output of lobsters, the conveyor belts of the spraying mechanism and the ultrasonic cleaning tank rotate at the same speed, so that the lobsters are spread out relatively evenly on the surface of the conveyor belt.
[0008] The present invention is further configured as follows: the roller screening mechanism includes a screening drum rotatably mounted on the frame. The rotation axis of the screening drum is parallel to the feeding direction of the feeding conveyor belt. The screening drum has an internal hollow structure, and the side wall is frustoconical. The small diameter end is close to the discharge end of the feeding conveyor belt. Several screen holes are opened on the side wall of the screening drum along the rotation axis. The diameter of the screen holes increases sequentially along the feeding direction. A first motor providing driving force is provided at the end of the screening drum. A heavy screening material storage frame is provided below the end of the screening drum to receive unscreened materials.
[0009] By adopting the above technical solution, the rotating shaft of the screening drum is horizontal and its side wall is frustum-shaped. When the crayfish enters the drum, it will move away from the inlet under the action of gravity. When the drum rotates, the crayfish will be lifted up and touch the drum wall until it falls to the bottom through the screen holes of the appropriate size. When the crayfish have passed through the entire drum without being successfully separated, they will fall into the heavy screening material storage frame set at the bottom of the drum. After that, they can be separated manually or the crayfish in the frame can be poured into the feed inlet for separation again.
[0010] A further feature of this invention is that the material conveying mechanism includes a plurality of receiving conveyor belts arranged below the screening drum along the rotation axis of the screening drum. The receiving conveyor belts are separated by vertical insert plates. The receiving conveyor belts rise along the conveying direction of the conveyor belts, and a material separation plate is connected to the receiving conveyor belts perpendicular to the conveying direction of the conveyor belts.
[0011] By adopting the above technical solution, when the crayfish fall from the drum, it cannot be guaranteed that multiple crayfish will not overlap, affecting the subsequent cleaning steps. Therefore, a material separation plate is installed on the receiving conveyor belt so that the crayfish are laid flat on the surface of the conveyor belt in rows.
[0012] The present invention is further configured as follows: the spraying mechanism includes a horizontally arranged spraying mechanism conveyor belt, a plurality of water leakage grooves are opened through the surface of the spraying mechanism conveyor belt, a spraying box is arranged above the spraying mechanism conveyor belt, the spraying box includes a water storage tank and a plurality of pressurized spray heads arranged at the bottom of the water storage tank, the water outlet direction of the pressurized spray heads is vertically downward, and a water inlet pipe is connected to the side of the water storage tank.
[0013] By adopting the above technical solution, the cleaning solution is stored in a water tank and sprayed onto the surface of the crayfish under pressure by a pressurized spray head, removing large stains from the crayfish's surface. The stains washed off or the shrimp whiskers and legs broken off due to water pressure fall down into the residue separation and recycling mechanism through the water leakage channel through the surface of the conveyor belt.
[0014] A further feature of this invention is that the bottom of the water storage tank is provided with several inclined pressurized spray heads, the water outlet direction of the inclined pressurized spray heads is inclined to the upper plane of the conveyor belt of the spraying mechanism, and the angle between the water outlet direction of the inclined pressurized spray heads and the horizontal plane is 10-30 degrees.
[0015] By adopting the above technical solution, it is possible that large stains on the abdomen and other parts of the crayfish cannot be removed by only setting up vertical spray pressure spray heads. Therefore, inclined pressure spray heads are also set up, with the water outlet line inclined to the upper plane of the conveyor belt. When the crayfish passes by with the conveyor belt, the water flow sprayed from the spray head contacts the lower side of the crayfish at a certain angle first, so as to facilitate cleaning of that area.
[0016] The present invention is further configured as follows: the ultrasonic cleaning tank includes an inner cleaning tank installed on a frame, an ultrasonic generator is provided between the inner cleaning tank and the frame, a water inlet and a water exchange hole are provided on the side wall of the inner cleaning tank, a cleaning tank conveyor belt is provided inside the inner cleaning tank, and a conveyor belt pusher plate is connected to the surface of the cleaning tank conveyor belt.
[0017] By adopting the above technical solution, the cleaning pool conveyor belt has a V-shaped structure, consisting of a descending part that slowly immerses into the inner cleaning pool and an ascending part that rises out of the inner cleaning pool. After the lobsters are brought into the inner cleaning pool by the cleaning pool conveyor belt, the fine dirt is removed under the action of ultrasound. Then, the lobsters soaking in the inner cleaning pool or floating are pushed away by the conveyor belt pusher.
[0018] A further feature of this invention is that the residue separation and recycling mechanism includes a residue separation conveyor belt disposed below the conveyor belt of the spraying mechanism. The surface of the residue separation conveyor belt is provided with a plurality of water-dividing grooves, the aperture of which is smaller than that of the leakage grooves. A residue storage frame is provided at the end of the residue separation conveyor belt.
[0019] By adopting the above technical solution, a residue separation conveyor belt is set below the spraying mechanism. The water distribution trough on its surface can intercept most of the solid matter mixed in the sewage. Under the continuous movement of the residue separation conveyor belt, the intercepted solid matter is carried to the end of the conveyor belt. A residue storage box is set up to collect the sewage and carry out unified treatment.
[0020] A further feature of this invention is that the synchronous motor of the conveyor belt is connected to the drive shaft of the spray mechanism conveyor belt and the cleaning pool conveyor belt through a gear set, so that the spray mechanism conveyor belt and the cleaning pool conveyor belt are transported synchronously.
[0021] By adopting the above technical solution, synchronous motors are installed on the conveyor belts of the spraying mechanism and the cleaning pool, so that the speeds of the two conveyor belts are the same, thus preventing the lobsters from piling up.
[0022] A further feature of this invention is that a discharge storage frame is provided below the end of the discharge conveyor belt.
[0023] By adopting the above technical solution, the cleaned lobsters are piled up in the discharge storage box to await subsequent processing.
[0024] The beneficial effects of this utility model are:
[0025] 1. The roller screening mechanism enables rapid and precise volumetric screening of large quantities of crayfish raw materials, efficiently classifying them into multiple size grades, significantly improving processing efficiency and facilitating subsequent differentiated processing of crayfish of different sizes.
[0026] 2. A high-pressure spray system is used to powerfully pre-wash large impurities attached to the surface of the crayfish. Then, an ultrasonic cleaning tank is used to deeply clean the dirt in the crevices and abdomen of the crayfish by taking advantage of the cavitation effect. This cleaning method greatly improves the cleaning efficiency per unit time and ensures cleanliness and hygiene standards. At the same time, it significantly reduces the damage to the crayfish that may be caused by traditional mechanical brushing or long-term soaking, ensuring the relative integrity of the crayfish and facilitating further processing.
[0027] 3. By implementing efficient solid-liquid separation at the front end of sewage discharge through a residue separation and recycling mechanism, solid waste in sewage is separated through physical filtration, which effectively prevents solid impurities from accumulating in drainage pipes, eliminates the risk of pipe blockage, and reduces maintenance costs. At the same time, the separated and collected solid residue can be centrally processed, realizing the resource reuse of waste. Attached Figure Description

[0033] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0034] This utility model embodiment specifically provides a disinfection device for lobster processing, including a frame 1, a feeding conveyor belt 11 horizontally arranged at one end of the frame 1, a roller screening mechanism 2 arranged at the end of the feeding conveyor belt 11, an inclined lifting conveyor mechanism 3 arranged below the roller screening mechanism 2, a spraying mechanism 4, an ultrasonic cleaning tank 5 and a discharge conveyor belt 6 arranged sequentially at the end of the lifting conveyor mechanism 3 along the rotation direction of the conveyor belt, a residue separation and recycling mechanism 7 arranged below the spraying mechanism 4, and a conveyor belt synchronous motor 8 arranged on the side from the spraying mechanism 4 to the ultrasonic cleaning tank 5.
[0035] This device is mainly used for cleaning and disinfecting lobsters or crayfish to ensure the cleanliness and hygiene of the raw materials during subsequent processing such as shrimp tail extraction. In use, the operator pours the lobsters onto the feeding conveyor belt 11, which transports them into the roller screening mechanism 2 for sorting based on size. The sorted crayfish fall onto the lifting conveyor mechanism 3 and are spread out evenly. The lifting conveyor mechanism 3 then transfers them to the spraying mechanism 4, where large stains and dirt residue are washed away. Finally, they pass through the ultrasonic cleaning tank 5 to remove fine impurities. The small, uncleaned parts of the crayfish are sent to the next process via the discharge conveyor belt 6. The spraying mechanism 4 generates a large amount of sewage and debris such as crayfish whiskers and broken limbs during use. The debris can be separated and collected by the debris separation and recycling mechanism 7. At the same time, the sewage without large solid particles is directed to the drain to await the next process. In order to maintain a relatively stable output of crayfish, the conveyor belts of the spraying mechanism 4 and the ultrasonic cleaning tank 5 rotate at the same speed to ensure that the crayfish are relatively evenly spread on the surface of the conveyor belt.
[0036] Specifically, the roller screening mechanism 2 includes a screening roller 21 rotatably mounted on the frame 1. The rotation axis of the screening roller 21 is parallel to the feeding direction of the feeding conveyor belt 11. The screening roller 21 has an internal hollow structure, and the side wall is truncated cone-shaped. The small diameter end is close to the discharge end of the feeding conveyor belt 11. Several screen holes 211 are opened on the side wall of the screening roller 21 along the rotation axis. The diameter of the screen holes 211 increases sequentially along the feeding direction. A first motor 22 providing driving force is provided at the end of the screening roller 21. A heavy screening material storage frame 23 is provided below the end of the screening roller 21 to receive materials that have not been successfully screened.
[0037] The rotating shaft of the screening drum 21 is set horizontally along the feeding direction. Since its side wall is frustum-shaped, when the crayfish enters the drum, it will continuously move away from the inlet under the action of gravity. Through the rotation of the drum, the crayfish are constantly lifted up and touch the drum wall until they fall down through the screen holes 211 of appropriate size. Since the aperture of the screen holes 211 increases sequentially along the feeding direction, the further away from the inlet, the larger the volume of the falling crayfish. By placing a separating frame or conveyor belt under the drum, the crayfish of different sizes can be processed separately. When the crayfish have passed through the entire drum without being successfully separated, they will fall into the heavy screening material storage frame 23 set below the end of the drum 21. After that, they can be separated manually or the crayfish in the frame can be poured back to the feed inlet for separation again.
[0038] Furthermore, the material lifting and conveying mechanism 3 includes a plurality of receiving conveyor belts 31 arranged below the screening drum 21 along the rotation axis of the screening drum 21. The receiving conveyor belts 31 are separated by vertical insert plates 32. The receiving conveyor belts 31 are raised along the conveying direction of the conveyor belt, and a material separation plate 33 is connected to the receiving conveyor belts 31 perpendicular to the conveying direction of the conveyor belt.
[0039] By using insert plates 32 to separate the receiving conveyor belt 31, crayfish of different sizes can be transported and cleaned separately, facilitating subsequent processes such as packaging crayfish according to quality. When crayfish fall from the roller, it's impossible to guarantee that multiple crayfish won't overlap, affecting subsequent cleaning steps. Therefore, a material separation plate 33 is installed on the receiving conveyor belt 31. The height of the material separation plate 33 is no higher than the thickness of two crayfish stacked together. Simultaneously, the conveyor belt 31 is raised along the conveying direction, and its inclination angle allows the crayfish to slide naturally without being blocked by the material separation plate 33. With this design, the crayfish are only held in place by the material separation plate 33 as they are conveyed and raised row by row, preventing overlapping and facilitating further cleaning. Figure 1 The text only indicates two cases based on the insertion plate; without loss of generality, receiving conveyor belts can also be divided into many more types.
[0040] Specifically, the spraying mechanism 4 includes a horizontally arranged spraying mechanism conveyor belt 41, with several water leakage grooves 411 extending through the surface of the spraying mechanism conveyor belt 41, and a spraying box 42 arranged above the spraying mechanism conveyor belt 41. The spraying box 42 includes a water storage tank 421 and several pressurized spray heads 422 arranged at the bottom of the water storage tank 421. The water outlet direction of the pressurized spray heads 422 is vertically downward, and a water inlet pipe 423 is connected to the side of the water storage tank 421.
[0041] The cleaning solution is stored in the water tank 421 and is sprayed onto the surface of the crayfish under pressure by the pressurized spray head 422, removing large stains from the crayfish surface. This pressurization technology can use mature existing technologies such as high-pressure water guns, which are not within the scope of this utility model. The stains washed off or the shrimp whiskers, legs, etc. that are broken off due to water pressure fall down into the residue separation and recycling mechanism 7 through the water leakage channel 411 that runs through the surface of the conveyor belt 41. It should be noted that the aperture of the water leakage channel 411 should be smaller than the minimum aperture of the sieve hole 211 to prevent the crayfish from falling down and causing waste of raw materials.
[0042] During implementation, the bottom of the water storage tank 421 is also equipped with several inclined pressurized spray heads 424. The water outlet direction of the inclined pressurized spray heads 424 is inclined towards the upper plane of the spray mechanism conveyor belt 41, and the angle between the water outlet direction of the inclined pressurized spray heads 424 and the horizontal plane is 10-30 degrees.
[0043] Setting only vertically spraying pressurized spray heads may result in large stains on areas such as the crayfish's abdomen not being removed. Therefore, an inclined pressurized spray head 424 is also installed. Its principle is the same as that of the pressurized spray head 422, but the water outlet line is inclined to the upper plane of the conveyor belt 41. Therefore, when the crayfish passes by with the conveyor belt, the water flow from the spray head first contacts the lower side of the crayfish at a certain angle, making it easier to clean that area. When the angle between the water outlet direction of the inclined pressurized spray head 424 and the horizontal plane is 10-30 degrees, the contact point between the water flow line and the crayfish is low enough, resulting in the most comprehensive cleaning range.
[0044] Specifically, the ultrasonic cleaning tank 5 includes an inner cleaning tank 51 installed on the frame 1. An ultrasonic generator 53 is provided between the inner cleaning tank 51 and the frame 1. A water inlet 511 and a water exchange hole 512 are provided on the side wall of the inner cleaning tank 51. A cleaning tank conveyor belt 52 is provided inside the inner cleaning tank 51. A conveyor belt pusher plate 521 is connected to the surface of the cleaning tank conveyor belt 52.
[0045] Ultrasonic cleaning utilizes ultrasonic waves to generate high-frequency vibrations in a cleaning solution, forming microbubbles. The energy released when these bubbles burst removes dirt, thus achieving the cleaning purpose. Specifically, the ultrasonic generator 53 can employ a conventional 40-50kHz vibration frequency technology, enabling deep cleaning while minimizing crayfish mortality. The cleaning tank conveyor belt 52 has a V-shaped structure, consisting of a descending section that slowly immerses the crayfish in the inner cleaning tank 51 and an ascending section that rises away from the inner cleaning tank 51. After the crayfish are carried into the inner cleaning tank 51 by the conveyor belt 52, they are subjected to ultrasonic... The action removes fine stains, and since the spray mechanism 4 has already removed large stains, the stains remaining in the cleaning tank 51 are relatively small and can flow out through the water exchange hole 512 without clogging the water hole. In addition, since there are fewer stains left after the second cleaning, the cleaning solution replacement speed in the cleaning tank 51 will also be reduced, effectively saving costs. The conveyor belt push plate 521 and the material separation plate 33 have the same main function, which is to prevent lobsters from piling up and reducing the cleaning effect. At the same time, the conveyor belt push plate 521 can also push away the lobsters that float in the cleaning tank 51.
[0046] Furthermore, the residue separation and recycling mechanism 7 includes a residue separation conveyor belt 71 disposed below the spray mechanism conveyor belt 41. The surface of the residue separation conveyor belt 71 is provided with a plurality of water-dividing grooves 711. The aperture of the water-dividing grooves 711 is smaller than the aperture of the water-leaking grooves 411. A residue storage frame 72 is provided at the end of the residue separation conveyor belt 71.
[0047] The residue separation and recycling mechanism 7 is for further recycling the stains and lobster fragments washed down by the spray mechanism 4. In order to prevent sewage from clogging the drain pipe, a residue separation conveyor belt 71 is set below the spray mechanism 4. The aperture of the water distribution groove 711 on its surface is smaller than that of the leakage groove 411, which can intercept most of the solid matter mixed in the sewage. Under the continuous movement of the residue separation conveyor belt 71, the intercepted solid matter is carried to the end of the conveyor belt, where a residue storage box 72 is set to collect the sewage and process it uniformly.
[0048] The synchronous motor 8 of the conveyor belt is connected to the drive shaft of the spray mechanism conveyor belt 41 and the cleaning pool conveyor belt 52 through a gear set, so that the spray mechanism conveyor belt 41 and the cleaning pool conveyor belt 52 are transmitted synchronously.
[0049] To prevent the crayfish from piling up, a synchronous motor 8 is installed on the spray mechanism conveyor belt 41 and the cleaning pool conveyor belt 52 to make the speed of the two conveyor belts the same, so that the crayfish are evenly spread on the conveyor belt during the transmission process. The manufacturing method of the synchronous motor 8 is not the problem to be solved by this utility model, and its specific manufacturing method can refer to the existing technical solutions.
[0050] During implementation, a discharge storage box 61 is set below the end of the discharge conveyor belt 6, and the cleaned lobsters are piled up in the discharge storage box 61 to await subsequent processing.
[0051] Working principle:
[0052] The device is started, and the operator pours the crayfish onto the feeding conveyor belt 11. The crayfish are sent into the roller screening mechanism 2, where they are separated into different receiving conveyor belts 31 by the rotating screening roller. Then, the crayfish are dispersed on the conveyor belt by the material separation plate 33 on the receiving conveyor belt 31 and transported to the spraying mechanism 4. Most of the large stains are cleaned by the pressurized spray head 422 and the inclined pressurized spray head 424. Then, the fine stains are removed by the ultrasonic cleaning tank 5. Finally, the crayfish enter the discharge storage box 61 via the discharge conveyor belt 6 to wait for the next step of processing.
[0053] The above describes the basic principles, main features, and advantages of this utility model. The standard parts used in this utility model can all be purchased from the market, and the irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts, and equipment all adopt conventional models in the prior art, which will not be described in detail here.
[0054] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
