Description

Technical Field

[0001] This utility model relates to the field of eel processing technology, and in particular to a cleaning device for eel production. Background Technology

[0002] Eels, as one of my country's main freshwater farmed fish species, have become a major contributor to my country's aquatic product exports and foreign exchange earnings. However, my country's eel processing technology is relatively backward, with fragmented processing equipment and low automation. Most enterprises still rely on simple, scattered manual labor for production, such as freezing, cutting, and cleaning.

[0003] Cleaning is a crucial step in eel production. Before slaughtering, eels are often pre-frozen and then placed in a cleaning drum where they are washed with water and detergent. After cleaning, the wastewater needs to be drained before the eels are removed. This means that batch processing can only be repeated. This method requires repeated water filling and drainage, resulting in low cleaning efficiency. Furthermore, dirt does not easily settle during the cleaning process, leading to prolonged periods of murky water cleaning. Water utilization is relatively low, affecting the quality of cleaning. Utility Model Content

[0004] This invention provides a cleaning device for eel production, which helps to solve the problems of low efficiency, long-term turbid water cleaning, and relatively low water utilization rate when using drum cleaning machines to clean eels.

[0005] This utility model is implemented as follows:

[0006] A cleaning device for eel production includes a frame with a cleaning tank having a top opening. A sedimentation chamber is located at the bottom of the cleaning tank, and a drain pipe with openable / closeable control is located at the bottom of the sedimentation chamber. A stirring roller is installed inside the cleaning tank to agitate the eels within it. An overflow tank is located on one side of the frame near the cleaning tank, with an overflow hole at the connection between the overflow tank and the upper end of the cleaning tank. A return pipe is connected to the bottom of the overflow tank, and the output end of the return pipe extends to the inlet and / or outlet of the cleaning tank. An automatic discharge mechanism is installed at the outlet of the cleaning tank.

[0007] Based on the above technical solution, a filter screen is provided between the cleaning tank and the sedimentation chamber. The filter screen is used to prevent eels from sinking from the cleaning tank into the sedimentation chamber.

[0008] Based on the above technical solution, the overflow pool is equipped with a filter plate for filtering impurities.

[0009] Based on the above technical solution, the rotation axis of the tamping roller is set horizontally, and the two ends of the main shaft of the tamping roller are connected to the side wall of the cleaning tank through bearings. One end of the main shaft is also connected to a rotating drive component.

[0010] Based on the above technical solution, the main shaft is a cylindrical structure with perforations evenly distributed on its surface. Several blades are arranged symmetrically on the outer surface of the main shaft, and flexible plates are arranged on the radially outer ends of the blades relative to the main shaft.

[0011] Based on the above technical solution, the outer end of the flexible sheet is provided with several serrated portions.

[0012] Based on the above technical solution, the blade is provided with an anti-slip flange on its sidewall.

[0013] Based on the above technical solution, the automatic material discharge mechanism is a hoist, which includes an inclined conveyor belt with several partitions spaced on it. The lower end of the conveyor belt extends into the discharge area inside the cleaning tank, and the higher end of the conveyor belt is located outside the cleaning tank.

[0014] Based on the above technical solution, a spray frame is provided above the conveyor belt, and the spray frame is equipped with several spray heads. The spray heads are connected to external water pipes and / or return pipes through pipes.

[0015] Compared with the prior art, the present invention has at least the following advantages:

[0016] 1. Compared to existing drum-type washing machines that can only perform batch operations, requiring water filling and drainage after each wash, which is cumbersome and inefficient, this invention's washing device employs a continuous automatic washing method. Through the agitation of the mixing rollers, the eels are fully contacted with the washing water, significantly shortening the washing time. The automatic discharge mechanism, activated periodically, easily completes the discharge, and with appropriate replenishment, washing efficiency is greatly improved. For example, in the same amount of time, this invention's washing device can wash several times more eels than a traditional drum-type washing machine.

[0017] 2. Traditional drum-type cleaning machines do not allow dirt to settle easily during the cleaning process, resulting in prolonged turbidity and potentially leaving dirt residue on the eels' surfaces. This invention's cleaning device achieves water recycling through an overflow tank and return pipe, filtering the water during circulation to maintain relative cleanliness within the cleaning tank. Simultaneously, a sedimentation chamber is designed at the bottom of the cleaning tank, allowing impurities generated during cleaning to settle and accumulate promptly, reducing repeated contact with the eels during the cleaning process. This not only improves water quality stability but also enhances cleaning efficiency. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0028] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0030] Example 1: Combination Figures 1 to 5 This embodiment discloses a cleaning device for eel production, which solves the problems of low efficiency, prolonged cleaning in murky water, low water utilization, and poor cleaning quality caused by the current batch-based drum cleaning machine for eel cleaning. This cleaning device enables continuous cleaning of eels, improves cleaning efficiency and quality, increases water utilization, and reduces production costs.

[0031] like Figure 1 As shown, the cleaning device in this embodiment includes a frame 100, on which a cleaning tank 110 with a top opening is provided. The frame 100 mainly serves a load-bearing and supporting function, and is constructed from aluminum profiles. The cleaning tank 110 is the main area for cleaning eels, and its top opening design facilitates the insertion and removal of eels. A sedimentation chamber 111 is provided at the bottom of the cleaning tank 110, and a drain pipe 112 with controllable opening and closing is provided at the bottom of the sedimentation chamber 111. The function of the sedimentation chamber 111 is to allow dirt generated during the cleaning process to settle within it, and the settled dirt can be periodically discharged through the drain pipe 112, thereby maintaining the relative cleanliness of the water in the cleaning tank 110. In this embodiment, combined with... Figure 2 As shown, a filter screen 113 is provided between the cleaning tank 110 and the sedimentation chamber 111. The filter screen 113 is used to prevent eels from sinking from the cleaning tank 110 into the sedimentation chamber 111.

[0032] The cleaning tank 110 is equipped with a stirring roller 200, which can agitate the eels located in the cleaning tank 110. The setting of the stirring roller 200 can increase the frequency and intensity of contact between the eels and the cleaning water, making it easier to clean the dirt on the surface of the eels.

[0033] The rotating axis of the agitation roller 200 is horizontally set. Both ends of the main shaft 210 of the agitation roller 200 are connected to the sidewalls of the cleaning tank 110 via bearings. One end of the main shaft 210 is also connected to a rotary drive component (specifically a geared motor), which drives the agitation roller 200 to rotate, thereby agitating the eel. By agitating the eel with the agitation roller 200, the eel is brought into full contact with the cleaning water, accelerating the removal of dirt. Simultaneously, the continuous cleaning method avoids the cumbersome process of water injection and drainage in traditional batch operations, greatly improving cleaning efficiency.

[0034] Furthermore, in combination Figure 4 The main shaft 210 has a cylindrical structure with evenly distributed perforations on its surface. This design not only reduces the weight of the mixing roller 200 and the load on the rotating drive components, but also allows cleaning water to circulate both inside and outside the mixing roller 200, enhancing the cleaning effect. Several blades 220 are centrally symmetrically arranged on the outer surface of the main shaft 210, and flexible sheets 221 are positioned at the radially outer ends of the blades relative to the main shaft 210. The flexible sheets 221 prevent damage to the eel or the bottom filter 113 while effectively agitating the eel. In this embodiment, the flexible sheets 221 are made of rubber.

[0035] Combination Figure 1 and Figure 5 As shown, the frame 100 is provided with an overflow tank 120 on one side of the cleaning tank 110. An overflow hole 130 is provided at the connection between the overflow tank 120 and the upper end of the cleaning tank 110. When the water level in the cleaning tank 110 exceeds the height of the overflow hole 130, excess water will flow into the overflow tank 120 through the overflow hole 130. Furthermore, a return pipe 140 is connected to the bottom of the overflow tank 120. A water pump is installed on the return pipe 140 as a drive source. In this embodiment, the output end of the return pipe 140 extends to both the feed end and the discharge end of the cleaning tank 110. In other embodiments, it can be configured to output to only one of these locations. Thus, since a sedimentation chamber 111 is provided at the bottom of the cleaning tank 110, the upper layer of water in the cleaning tank 110 will be relatively clean. The overflowing water can return to the cleaning tank 110 through the return pipe 140, realizing water recycling and improving water utilization efficiency.

[0036] The overflow tank 120 is equipped with a filter plate 121 for filtering impurities. The filter plate 121 can filter out stains and impurities in the water, making the water returning to the cleaning tank 110 relatively clean.

[0037] The discharge end of the cleaning tank 110 is equipped with an automatic discharge mechanism. Combined with... Figure 3As shown, the automatic discharge mechanism is a hoist 300, which includes an inclined conveyor belt 310 with evenly distributed drainage holes on its surface and several partitions 320 spaced apart on the belt. The lower end of the conveyor belt 310 extends into the discharge area inside the cleaning tank 110, while the higher end is located outside the tank. A hopper 330 is also provided on this side to guide and constrain the cleaned eels, facilitating loading with an external receiving device. After cleaning, the eels can be automatically discharged from the cleaning tank 110 without manual intervention, improving the automation level of production. Furthermore, a spray frame 400 is installed above the conveyor belt 310, with several spray heads connected to an external water pipe and a return pipe 140 via pipes. In other embodiments, a single water supply source can also be used, which can be freely selected according to the actual operating conditions. During the eel's discharge process, the spray nozzles can further rinse the eel to ensure that its surface is clean.

[0038] Example 2: Based on Example 1, combined with Figure 6 As shown, in this embodiment, the outer end of the flexible sheet 221 is provided with a plurality of serrated portions 222. The serrated portions 222 can increase the contact area and friction with the eel, further improving the cleaning effect. The side wall of the blade 220 is provided with an anti-slip flange 223, which can prevent the eel from slipping during the stirring process and ensure that the eel can be fully agitated.

[0039] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
