Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a device for the resource-based treatment of crayfish processing wastewater. Background Technology

[0002] The processing of crayfish generates a large amount of wastewater containing crayfish shell fragments, undigested feed residue, dissolved protein, and suspended solids. This type of wastewater has high chemical oxygen demand and suspended solids content. If discharged directly without effective treatment, it will not only cause eutrophication of water bodies and lead to environmental pollution, but also waste recyclable resources, which is inconsistent with the current requirements for resource recycling and green development.

[0003] Currently, traditional methods for treating crayfish processing wastewater mostly involve manual scooping or simple filtration screens to initially separate larger particulate impurities. However, these methods have several shortcomings: firstly, they rely on manual labor, resulting in high labor intensity and low efficiency, making it difficult to meet the demands of large-scale, continuous production in modern food processing industries; secondly, existing equipment lacks effective interception and centralized collection capabilities for impurities, easily leading to clogging and decreased filtration efficiency, affecting the stable operation of subsequent wastewater treatment systems and hindering the efficient extraction and resource utilization of effective components from the wastewater.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in related technologies, this utility model proposes a crayfish processing wastewater resource treatment device to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows: A wastewater resource utilization device for crayfish processing includes a drainage cylinder, a support base connected to the bottom of the inner wall of the drainage cylinder, a limit groove on the surface of the support base, a filter cylinder inside the drainage cylinder, a positioning bearing installed at the bottom of the filter cylinder, a positioning block rotatably installed inside the positioning bearing, the bottom of the positioning block cooperating with the limit groove, a high-efficiency filtration mechanism between the drainage cylinder and the filter cylinder, and a filtration transmission mechanism on one side of the high-efficiency filtration mechanism.

[0007] Furthermore, in order to achieve efficient filtration of crayfish processing wastewater, the efficient filtration mechanism includes a transmission groove at the top of the drain cylinder, a positioning rod slidably installed inside the transmission groove, a cleaning scraper connected to one side of the positioning rod, and multiple filter screens installed on the surface of the filter cylinder, with the cleaning scraper sliding in contact with the inner wall of the filter cylinder.

[0008] Furthermore, in order to provide power to the high-efficiency filtration mechanism, the filtration transmission mechanism includes a drive motor installed at the bottom of the drain cylinder, a drive gear connected to the drive shaft of the drive motor, a driven gear ring installed at the bottom of the outer surface of the drain cylinder, the drive gear meshing with the driven gear ring, and a stirring rod installed inside the filter cylinder.

[0009] Furthermore, in order to control the discharge of filtered water from the drain cylinder, a drain pipe is installed on one side of the bottom of the drain cylinder, and a drain valve is installed on the surface of the drain pipe.

[0010] Furthermore, to facilitate the removal of the filter cartridge from the drain cylinder, lifting rings are connected to both sides of the top of the filter cartridge.

[0011] Furthermore, in order to enable the drainage cylinder to be moved and supported, casters are rotatably installed at the bottom of the drainage cylinder.

[0012] Furthermore, in order to control the switching of the drive motor, a control switch is installed on one side of the surface of the drain cylinder.

[0013] The beneficial effects of this utility model are as follows: the filter cylinder inside the high-efficiency filter mechanism is rotated by the filter transmission mechanism, so that the crayfish processing wastewater that needs to be treated for resource recovery is injected into the filter cylinder, thereby achieving efficient filtration of the wastewater. Solid impurities such as crayfish shell fragments and feed residue in the wastewater are blocked and collected in the filter cylinder. Compared with the traditional manual harvesting method, the operation is simple, the processing efficiency is high, and the labor intensity is significantly reduced. While the filter cylinder is rotating and filtering, the cleaning scraper installed on the drain cylinder can continuously clean the inside of the filter cylinder, effectively preventing the filter cylinder from clogging and further improving the separation efficiency. The filtered wastewater and the collected residue can be reused as resources, which has good environmental and economic benefits. Attached Figure Description

A high-efficiency filtration mechanism 7 is provided between the drainage cylinder 1 and the filter cylinder 4 for rapid filtration of crayfish processing wastewater and collection of residues in the wastewater. A filter transmission mechanism 8 is provided on one side of the high-efficiency filtration mechanism 7 for driving the filter cylinder 4 to rotate inside the drainage cylinder 1 and providing power to the high-efficiency filtration mechanism 7.

[0020] like Figures 1-4As shown, the high-efficiency filtration mechanism 7 includes a transmission groove 701 on the top of the drain cylinder 1.

Multiple filter screens 704 are installed on the surface of the filter cylinder 4 to separate and filter impurities in the crayfish processing wastewater. The cleaning scraper 703 slides in contact with the inner wall of the filter cylinder 4. When the filter cylinder 4 rotates inside the drain cylinder 1, the cleaning scraper 703 and the positioning rod 702 are limited by the transmission groove 701. The filter cylinder 4 remains stationary, allowing the cleaning scraper 703 to clean and scrape the inner wall of the continuously rotating filter cylinder 4, preventing the filtered residue from clogging the filter screen 704, and enabling the filter cylinder 4 to continuously and efficiently filter crayfish processing wastewater; the filter transmission mechanism 8 includes a transmission motor 801 installed at the bottom of the drain cylinder 1, the transmission motor 801 is a waterproof motor, the transmission shaft of the transmission motor 801 is connected to the drive gear 802, the outer surface bottom of the drain cylinder 1 is installed with a driven gear ring 803, the drive gear 802 and the driven gear ring 803 are meshed and connected, and the filter cylinder 4 is equipped with a... The stirring rod 804 drives the drive gear 802 to rotate via the transmission motor 801.
