Description

Technical Field

[0001] This invention belongs to the technical field of wastewater treatment equipment, specifically relating to a wastewater treatment device for konjac product production. Background Technology

[0002] The production of konjac products generates a large amount of wastewater. This wastewater contains a lot of solid impurities such as konjac residue and debris, and the water quality is complex. Direct discharge will cause serious pollution to the surrounding water bodies and soil environment, which does not meet the national requirements for green, environmentally friendly, energy-saving and efficient industrial development. Therefore, konjac production wastewater must be pre-treated and deeply treated before it can be discharged in compliance with standards.

[0003] Currently, most wastewater treatment equipment for konjac product manufacturing uses traditional bar screens for wastewater pretreatment to intercept solid impurities. However, this type of equipment generally suffers from numerous technical defects and fails to meet actual production needs. Firstly, existing bar screens are mostly planar structures, capable of intercepting only larger solid impurities. Small impurities in the wastewater easily clog the screen pores, requiring frequent manual disassembly and cleaning. This not only affects the continuity of wastewater treatment and increases labor intensity but also reduces wastewater pretreatment efficiency. Secondly, the components used for cleaning impurities from the bar screen in existing equipment often require additional power sources, resulting in high energy consumption, increased operating costs, and incomplete dehydration of impurities, leading to low subsequent wastewater discharge efficiency. Therefore, those skilled in the art have provided a wastewater treatment device for konjac product manufacturing to solve the aforementioned problems. Summary of the Invention

[0004] The purpose of this invention is to provide a wastewater treatment device for konjac product production that is simple in structure and reasonably designed in order to solve the above-mentioned problems.

[0005] The present invention achieves the above objectives through the following technical solutions: A wastewater treatment device for konjac product production includes a frame fixedly installed on the outer wall of the wastewater treatment tank. A bar screen is provided on both the frame and the inner wall of the wastewater treatment tank. The bar screen includes a second rotating shaft that rotates through the bottom two sides of the inner wall of the wastewater treatment tank and the top two sides of the inner wall of the frame. A transmission gear disc located inside the frame is fixedly sleeved at both ends of the outer wall of the two second rotating shafts. The four transmission gear discs are arranged in a rectangular array. A reciprocating transmission belt is sleeved between the upper and lower opposing transmission gear discs on both sides. A grooved bar screen is fixedly installed between the two reciprocating transmission belts. A plurality of arrayed filter holes are opened through the inner wall of the grooved bar screen. A cleaning brush is fixedly sleeved on the outer side wall of the upper second rotating shaft, located between the corresponding transmission gear discs. The cleaning brush is made of elastic material, and the brush on the cleaning brush is movably inserted into the filter hole. Fixed plates are fixedly installed on both sides of the top of the inner side wall of the frame, and a driven extrusion cleaning assembly is provided between the two fixed plates. A sewage discharge assembly that cooperates with the driven extrusion cleaning assembly and the bar screen is fixedly installed on the rear side wall of the frame. The frame is fixedly equipped with a backwashing assembly located below the cleaning brush. The backwashing assembly is respectively engaged with the driven extrusion cleaning assembly, filter holes, grooved grid and cleaning brush.

[0006] As a further optimization of the present invention, the driven extrusion cleaning assembly includes a first rotating shaft rotatably connected to the inner sidewalls of two fixed plates, and the outer sidewall of the first rotating shaft is fixedly sleeved with extrusion cleaning teeth that mesh with the grooved grid.

[0007] As a further optimization of the present invention, a servo motor for driving the upper second rotating shaft to rotate is fixedly installed on the side wall of the frame, and pulleys are fixedly sleeved on the other end of the two second rotating shafts, and a transmission belt is sleeved between the two pulleys.

[0008] As a further optimization of the present invention, the backwashing assembly includes a diversion pipe that is fixedly penetrates the inner wall of the frame. Above the diversion pipe and inside the filter holes, there are a plurality of inclined nozzles and horizontal nozzles fixedly installed on the inner wall of the frame. The inlet end of each inclined nozzle is fixedly connected to a first control pipe, and the inlet end of each horizontal nozzle is fixedly connected to a second control pipe. The other ends of the plurality of first control pipes and the plurality of second control pipes are fixedly connected to the distribution branch pipe of the diversion pipe.

[0009] As a further optimization of the present invention, the inclined nozzles and horizontal nozzles are arranged in an alternating array, with the nozzles of the inclined nozzles facing the cleaning brush, the upper side of the filter holes and the side of the squeezing cleaning teeth.

[0010] As a further optimization of the present invention, a liquid pump is fixedly installed on the side wall of the frame, the inlet end of the liquid pump is fixedly connected to a water inlet pipe, the outlet end of the liquid pump is fixedly connected to a water delivery pipe, and the other end of the water delivery pipe is fixedly penetrated through the side wall of the frame and fixedly connected to the inlet end of the diversion pipe.

[0011] As a further optimization of the present invention, the sewage discharge assembly includes a receiving box fixedly installed on the rear side wall of the frame, a cylinder fixedly installed on the side wall of the receiving box, the output end of the cylinder slidingly penetrating through the inner side wall of the receiving box, a push plate fixedly connected to the output end of the cylinder, and a guide pipe fixedly connected to the discharge end of the receiving box.

[0012] As a further optimization of the present invention, a sludge box with a guide pipe discharge end is fixedly installed on one side of the wastewater treatment tank, and a discharge port is opened at the discharge end of the wastewater treatment tank.

[0013] As a further optimization of the present invention, the inner wall of the sludge tank is provided with an inclined guide surface, which faces the feed end of the guide pipe.

[0014] As a further optimization of the present invention, the outer side wall of the push plate is fixedly wrapped with a sealing rubber gasket, and the sealing rubber gasket is tightly fitted to the inner side wall of the receiving box.

[0015] The beneficial effects of this invention are as follows: 1. In this invention: the bar screen adopts a dual interception structure combining a grooved bar screen and filter holes. The grooved bar screen can stably receive and transport solid impurities in wastewater, preventing impurities from falling off, while the filter holes further intercept fine impurities, improving pretreatment accuracy. At the same time, a cleaning brush and a backwashing component are provided. The cleaning brush moves synchronously with the bar screen, inserting into the filter holes in real time to clean the fine impurities that are clogging them. The backwashing component uses multiple nozzles to flush in all directions, achieving real-time self-cleaning of the filter holes and bar screen. This completely solves the problems of easy clogging and cumbersome cleaning of existing equipment bar screens, ensuring continuous and stable wastewater pretreatment and significantly improving treatment efficiency.

[0016] 2. In this invention: the driven extrusion cleaning assembly adopts a meshing transmission design, which does not require an additional power source. Through the cyclic movement of the grooved grid, the meshing action drives the extrusion cleaning teeth to rotate synchronously, which not only extrudes and dehydrates impurities, but also pushes the impurities to the sewage discharge assembly. On the one hand, it saves the energy consumption of an additional power source and reduces the operating cost of the equipment. On the other hand, the volume of impurities is reduced after dehydration, which effectively improves the efficiency of subsequent sewage discharge and reduces the manpower and material input in the sewage discharge process.

[0017] 3. In this invention: the backwashing assembly adopts an alternating array of inclined nozzles and horizontal nozzles. The inclined nozzles specifically rinse and clean the brush, the upper side of the filter hole, and the squeezing cleaning teeth, while the horizontal nozzles focus on rinsing the inner side of the grooved grid. This achieves all-round, no-dead-angle rinsing of key components such as the grid machine, the squeezing cleaning assembly, and the cleaning brush, thoroughly removing impurities attached to the surface of the components, reducing component wear and corrosion, extending equipment service life, and reducing equipment maintenance costs.

[0018] 4. In this invention: By rationally arranging the components, wastewater filtration, impurity interception, extrusion dewatering, self-cleaning, and centralized sewage discharge are integrated and coordinated. The servo motor drives the bar screen to operate continuously, the backwashing component works synchronously, and the sewage discharge component automatically collects and transports impurities, eliminating the need for frequent manual intervention and ensuring convenient and efficient operation. Simultaneously, the servo motor can precisely adjust its speed to adapt to the treatment needs of konjac wastewater of different concentrations, making it widely applicable to the wastewater pretreatment stage of various konjac product manufacturing enterprises, offering greater adaptability. A sludge tank is set up to centrally collect solid impurities and sludge after extrusion dewatering, which can then be processed into organic fertilizer, achieving pollutant reduction and resource utilization. This reduces solid waste emissions and realizes resource recycling, aligning with the green, environmentally friendly, energy-efficient, and high-efficiency industrial development trend, and possessing significant environmental and economic benefits.

[0021] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] Example 1: As Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, a wastewater treatment device for konjac product production includes a wastewater treatment tank 1. The wastewater treatment tank 1, as the core carrier for wastewater treatment, is constructed from corrosion-resistant, high-strength materials, resulting in a stable structure. It stores the wastewater from konjac product production, providing a stable working space for subsequent filtration and purification operations. Its internal water level control structure can be preset as needed to ensure a smooth and orderly wastewater treatment process. Flocculants are added to the wastewater treatment tank 1 to cause colloidal impurities and fine suspended solids in the wastewater to agglomerate into larger flocs, facilitating subsequent interception and filtration. Wastewater generated during konjac product production is then transported to the wastewater treatment tank 1 through pipelines, controlling the wastewater level within a preset range. A frame 2 is fixedly installed on the outer wall of the wastewater treatment tank 1. The frame 2 is welded from steel, resulting in a compact overall structure that provides robust installation support for components such as the bar screen 5, the driven extrusion cleaning assembly 4, and the backwashing assembly 7, ensuring that the components do not shake or shift during coordinated operation and guaranteeing equipment operational stability.

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, a bar screen 5 is installed on the inner wall of both the frame 2 and the wastewater treatment tank 1. The bar screen 5, as a core component of wastewater pretreatment, is used to intercept and separate solid impurities such as konjac residue and debris from the konjac wastewater, laying the foundation for subsequent deep wastewater treatment. The bar screen 5 includes four second rotating shafts 505 that rotate through the bottom two sides of the inner wall of the wastewater treatment tank 1 and the top two sides of the inner wall of the frame 2, respectively. These four second rotating shafts 505 are symmetrically distributed, providing stable rotational support for the transmission gear disc 504 and the reciprocating transmission belt 502. To ensure smooth and uninterrupted transmission, transmission gear discs 504 are fixedly fitted at both ends of the outer walls of the two second rotating shafts 505, located inside the wastewater treatment tank 1 and the frame 2. The four transmission gear discs 504 are arranged in a rectangular array. Reciprocating transmission belts 502 are fitted between the opposing transmission gear discs 504 on both sides. The reciprocating transmission belts 502 are made of high-strength, wear-resistant material and can rotate synchronously with the transmission gear discs 504 to achieve cyclic reciprocating motion. A grooved grid 50 is fixedly installed between the two reciprocating transmission belts 502. 3. The grooved screen 503 has a long, narrow groove structure, which can receive and transport solid impurities in wastewater, preventing impurities from falling and improving the interception effect. The inner sidewall of the grooved screen 503 has several arrayed filter holes 508, which can further intercept fine impurities in wastewater, improve pretreatment accuracy, and prevent fine impurities from entering subsequent treatment stages and causing blockages. The outer sidewall of the upper second rotating shaft 505 is fixedly fitted with a cleaning brush 10 located between the corresponding transmission gear discs 504. The cleaning brush 10 uses a spring-loaded... Made of a flexible material, it has good elastic deformation ability and can adapt to the movement trajectory of the filter hole 508, avoiding wear on the filter hole 508; the brush on the cleaning brush 10 is movably inserted into the filter hole 508. When the grooved grid 503 moves to the position of the cleaning brush 10 with the reciprocating transmission belt 502, the cleaning brush 10 rotates synchronously with the second rotating shaft 505, and the brush is inserted into the filter hole 508, which can effectively clean the small impurities that clog the filter hole, realize the real-time self-cleaning of the filter hole 508, and avoid the filter hole 508 from being clogged and affecting the wastewater treatment efficiency.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 8 and Figure 9As shown, two fixing plates 3 are fixedly installed on the top two sides of the inner sidewall of the frame 2. The two fixing plates 3 are symmetrically distributed and have a stable structure, providing a reliable installation base for the driven extrusion cleaning assembly 4. The driven extrusion cleaning assembly 4 is provided between the two fixing plates 3. The driven extrusion cleaning assembly 4 is used to extrude and clean the solid impurities intercepted in the grooved bar screen 503, preventing impurities from accumulating in the groove and ensuring the continuous and stable operation of the bar screen 5. The driven extrusion cleaning assembly 4 includes a first one that is rotatably connected to the inner sidewall of the two fixing plates 3. The first rotating shaft 401 can rotate flexibly around the fixed plate 3. Its outer side wall is fixedly sleeved with extrusion cleaning teeth 402 that mesh with the grooved screen 503. When the grooved screen 503 moves with the reciprocating transmission belt 502, the extrusion cleaning teeth 402 are driven to rotate synchronously through the meshing action. During the rotation of the extrusion cleaning teeth 402, the solid impurities in the grooved screen 503 are squeezed, the water in the impurities is squeezed out, and the impurities are pushed to the sewage discharge component 8, so as to achieve efficient cleaning and dehydration of impurities and improve the subsequent sewage discharge efficiency.

[0025] like Figure 1 - Figure 3 As shown, a servo motor 501 is fixedly installed on the side wall of the frame 2 to drive the upper second rotating shaft 505 to rotate. The servo motor 501 is the core power source of the bar screen 5 and can achieve precise speed adjustment to adapt to the treatment needs of wastewater with different concentrations. The other ends of the two second rotating shafts 505 are fixedly fitted with pulleys 506, and a transmission belt 507 is fitted between the two pulleys 506. After the servo motor 501 is started, it drives the upper second rotating shaft 505 to rotate. Through the transmission action of the pulleys 506 and the transmission belt 507, the lower second rotating shaft 505 is driven to rotate synchronously, which in turn drives the transmission gear 504, the reciprocating transmission belt 502 and the grooved bar screen 503 to circulate, so as to realize the continuous filtration of wastewater.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 8 and Figure 9As shown, a backwashing assembly 7 is fixedly installed on the frame 2 below the cleaning brush 10. The backwashing assembly 7 cooperates with the squeezing cleaning teeth 402, filter holes 508, grooved grid 503, and cleaning brush 10 to perform comprehensive backwashing on the above components, remove impurities attached to the surface of the components, further improve the self-cleaning ability of the equipment, extend the service life of the equipment, and ensure stable wastewater treatment efficiency. The backwashing assembly 7 includes a diversion pipe 704 fixedly penetrating the inner wall of the frame 2. The diversion pipe 704 is used to evenly distribute the flushing water to each nozzle to achieve all-round flushing. Above the diversion pipe 704 and inside the filter holes 508, there are inclined nozzles 705 and horizontal nozzles 708 fixedly installed on the inner wall of the frame 2. The inlet end of nozzle 705 is fixedly connected to a first control pipe 706, and the inlet end of horizontal nozzle 708 is fixedly connected to a second control pipe 707. The other ends of several first control pipes 706 and second control pipes 707 are fixedly connected to the distribution branch pipe of the diversion pipe 704. The flushing water transported by the diversion pipe 704 is delivered to the inclined nozzle 705 and horizontal nozzle 708 respectively through the distribution branch pipe, the first control pipe 706 and the second control pipe 707, realizing precise delivery of flushing water. The inclined nozzles 705 and horizontal nozzles 708 are arranged in an alternating array. This distribution method can achieve flushing without dead corners, ensuring that impurities on the surface of each component can be effectively flushed. The nozzle of the inclined nozzle 705 faces the side and above the cleaning brush 10 and filter hole 508. On one side of the squeezing cleaning teeth 402, impurities attached to the cleaning brush 10, fine impurities on the surface and inside of the filter holes 508, and impurities remaining on the squeezing cleaning teeth 402 can be specifically rinsed; the horizontal nozzle 708 mainly faces the inside of the grooved grid 503 for secondary rinsing of impurities remaining in the groove, further improving the cleaning effect; a liquid pump 701 is fixedly installed on the side wall of the frame 2, which provides rinsing power for the backwashing assembly 7; its inlet end is fixedly connected to a water inlet pipe 702, which can be connected to an external clean water source or treated wastewater that meets standards, realizing the recycling of water resources and reducing operating costs; the outlet end of the liquid pump 701 is fixedly connected to a water delivery pipe 703, and the other end of the water delivery pipe 703 is fixed The pump 701 runs through the side wall of the frame 2 and is fixedly connected to the inlet end of the diversion pipe 704. After the pump 701 is started, it draws clean water through the inlet pipe 702, delivers it to the diversion pipe 704 through the water delivery pipe 703, and then sprays it out through each nozzle to complete the backwashing operation. The rear side wall of the frame 2 is fixedly installed with a sewage discharge assembly 8 that cooperates with the driven extrusion cleaning assembly 4 and the bar screen 5. The sewage discharge assembly 8 is used to collect and transport the solid impurities pushed by the driven extrusion cleaning assembly 4 to realize the centralized discharge and treatment of impurities. The sewage discharge assembly 8 includes a receiving box 801 fixedly installed on the rear side wall of the frame 2. The receiving box 801 is located below the extrusion cleaning teeth 402 and is used to receive the solid impurities after extrusion. Its inner side wall is made of a smooth material to facilitate the sliding of impurities and avoid accumulation.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, a cylinder 802 is fixedly installed on the side wall of the receiving box 801. The cylinder 802 serves as the power source for sewage discharge, and its output end slides through the inner side wall of the receiving box 801. A push plate 803 is fixedly connected to the output end of the cylinder 802 and slides against the inner side wall of the receiving box 801. The push plate 803 is tightly fitted with the inner side wall of the receiving box 801 to ensure that no impurities remain during the pushing process. A guide pipe 804 is fixedly connected to the discharge end of the receiving box 801. When the impurities in the receiving box 801 accumulate to a certain amount, the cylinder 802 is activated, driving the push plate 803 to slide along the inner side wall of the receiving box 801, pushing the impurities to the guide pipe 804, and then transporting them to the designated collection position through the guide pipe 804.

[0028] like Figure 1 - Figure 5 As shown, a sludge tank 6 is fixedly installed on one side of the wastewater treatment tank 1, which is matched with the discharge end of the guide pipe 804. The sludge tank 6 is used to collect the solid impurities and sludge transported by the guide pipe 804, which is convenient for subsequent centralized treatment and resource utilization, such as making organic fertilizer, to achieve the reduction and resource utilization of pollutants. The discharge end of the wastewater treatment tank 1 is provided with a discharge port 9. After the wastewater is filtered and pretreated by the bar screen 5, it is transported to the subsequent deep treatment stage, such as biochemical treatment and disinfection treatment, through the discharge port 9 to achieve the standard discharge. Compared with traditional wastewater treatment devices, this wastewater treatment device for konjac product production has the following core advantages: First, the bar screen 5 adopts a structure that combines a grooved bar screen 503 with filter holes 508, and with the cleaning brush 10 and backwashing assembly 7, it achieves filtration. The system features four main functions: 1) Self-cleaning holes effectively solve the problem of grid blockage; 2) Driven extrusion cleaning assembly 4 achieves impurity extrusion and cleaning through meshing transmission, requiring no additional power source, saving energy, and simultaneously dehydrating impurities to improve sewage discharge efficiency; 3) Backwashing assembly 7 uses staggered inclined nozzles 705 and horizontal nozzles 708 to achieve all-round, dead-angle-free rinsing, further improving the equipment's cleaning effect; 4) All components work together to achieve integrated operation of wastewater filtration, impurity cleaning, self-cleaning, and sewage discharge, resulting in high operating efficiency, convenient maintenance, and suitability for the treatment needs of konjac product production wastewater. It can be widely used in the wastewater pretreatment stage of various konjac product manufacturing enterprises, possessing significant economic, environmental, and practical benefits, and conforming to the industrial development trend of green environmental protection and energy efficiency.

[0029] It should be noted that, after the wastewater treatment device for konjac product production is started, flocculant is first added to the wastewater treatment tank 1 to cause colloidal impurities and fine suspended solids in the wastewater to agglomerate into larger flocs, which are easier to intercept and filter later. Then, the wastewater generated during the production of konjac products is transported to the wastewater treatment tank 1 through pipelines, and the wastewater level is controlled within a preset range. The servo motor 501 and the liquid pump 701 are started through the external control terminal. The servo motor 501 drives the upper second rotating shaft 505 to rotate, and drives the lower second rotating shaft 505 to rotate synchronously through the pulley 506 and the transmission belt 507, which in turn drives the transmission gear plate 504, the reciprocating transmission belt 502 and the grooved grid 503 to circulate. The liquid pump 701 draws clean water through the water inlet pipe 702, and delivers it to the inclined nozzle 705 and the horizontal nozzle 708 through the water delivery pipe 703, the diversion pipe 704, the first control pipe 706 and the second control pipe 707. The nozzles start to spray rinsing water and start the backwashing operation.

[0030] Wastewater filtration and impurity interception stage: Wastewater in wastewater treatment tank 1 comes into contact with grooved screen 503. Groove screen 503 intercepts larger solid impurities in the wastewater, and filter holes 508 further intercept smaller impurities. The filtered wastewater remains in wastewater treatment tank 1 and is transported to the subsequent deep treatment stage through discharge port 9. The intercepted solid impurities move upward with grooved screen 503 along with reciprocating transmission belt 502 and are transported to the position of driven extrusion cleaning assembly 4.

[0031] Impurity squeezing and cleaning stage: During the movement of the grooved screen 503, it meshes with the squeezing and cleaning teeth 402, causing the squeezing and cleaning teeth 402 to rotate around the first rotating shaft 401. The squeezing and cleaning teeth 402 squeeze the solid impurities in the grooved screen 503, squeezing out the water in the impurities. The squeezed water flows back to the wastewater treatment tank 1, while the squeezed impurities are pushed into the receiving box 801. Simultaneously, when the grooved screen 503 moves to the position of the cleaning brush 10, the cleaning brush 10 rotates with the upper second rotating shaft 505. The brush is inserted into the filter hole 508 to clean the small impurities that are clogging the filter hole. With the flushing action of the backwashing component 7, the filter hole 508, the grooved screen 503, the squeezing and cleaning teeth 402 and the cleaning brush 10 are thoroughly cleaned to prevent impurities from adhering and clogging.

[0032] Impurity discharge and equipment maintenance stage: When the impurities in the receiving box 801 accumulate to the preset amount, the cylinder 802 is activated. The cylinder 802 drives the push plate 803 to slide, pushing the impurities in the receiving box 801 to the guide pipe 804, and then transporting them to the sludge tank 6 for centralized collection. The backwashing component 7 continues to operate, cleaning the impurities on the surface of each component in real time to ensure the continuous and stable operation of the equipment. After the wastewater treatment is completed, the servo motor 501 and the liquid pump 701 are turned off, the impurities in the sludge tank 6 are centrally processed, the operating status of each component is checked, and routine maintenance is performed for future use.

[0033] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
