Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a wastewater treatment device for a beverage factory. Background Technology

[0002] With the rapid development of the beverage industry, the amount of wastewater generated during beverage production is increasing year by year. Beverage wastewater mainly originates from raw material washing, production equipment cleaning, and product bottling. Its characteristics include high organic matter content, high suspended solids concentration, and good biodegradability. It also contains a large amount of large particulate impurities such as fruit peels, pulp fibers, bottle residue, plastic packaging fragments, and labels, as well as sticky colloidal substances such as pectin and protein. If these impurities are not effectively removed in the pretreatment stage, they will enter the subsequent biological treatment unit, clogging aeration heads, pipes, and pumps, wearing down equipment, and even causing sludge poisoning in the bioreactor, seriously affecting the stable operation of the entire wastewater treatment system. Therefore, an efficient and stable pretreatment system is an indispensable and important component of beverage factory wastewater treatment equipment.

[0003] Currently, the pretreatment stage of beverage factory wastewater treatment commonly employs a combination of processes such as bar screens, rotary drum screens, grit chambers, and dissolved air flotation tanks. Among these, bar screens and sieves are the core equipment for removing large particulate impurities. However, existing bar screen and sieve devices have the following significant drawbacks: Firstly, the impurities intercepted by traditional bar screens and sieves mostly require regular manual removal and cleaning, especially during peak beverage production periods when the amount of impurities increases dramatically. This necessitates frequent cleaning operations, which is not only time-consuming and labor-intensive but also increases the company's labor costs. Furthermore, untimely cleaning can lead to filter clogging, a sharp reduction in the water flow area, a significant decrease in treatment capacity, and even wastewater overflow. Secondly, cleaning impurities usually requires stopping the machine for rinsing or replacing the filter screen, interrupting the continuous wastewater treatment process and affecting the overall system efficiency. Summary of the Invention

[0004] This invention overcomes the shortcomings of the prior art and proposes a wastewater treatment device for beverage factories.

[0005] This invention is achieved through the following technical solution: A wastewater treatment device for a beverage factory includes a reaction tank with a dosing mechanism installed above it. A purification cylinder is located at the top of one end of the reaction tank. The device also includes a coarse filter, a drive assembly, a fine filter, and a negative pressure nozzle. The coarse filter is installed inside the purification cylinder. Two arc-shaped scrapers, Arc 1 and Arc 2, are symmetrically arranged inside the coarse filter, with Arc 1 symmetrically arranged along the X-axis and Arc 2 symmetrically arranged along the Y-axis.

[0009] Furthermore, the top of the top cover is symmetrically connected to a water inlet pipe near the middle, the top of the sewage pipe is connected to an L-shaped pipe, the end of the L-shaped pipe away from the sewage pipe passes through the mounting frame and is connected to a sludge collection box, and a control cabinet is fixedly connected to the side wall of the reaction tank.

[0010] Furthermore, the drive assembly includes an electric push rod, a guide rod, a collar, and a vertical rod. The electric push rod is fixedly connected to the side wall of the purification cylinder. A cross-shaped frame is fixedly connected to the output end of the electric push rod, and the cross-shaped frame is slidably sleeved on the outer wall of the sewage pipe. Guide rods are fixedly connected to the bottom of the cross-shaped frame at equal intervals around the periphery. A collar is slidably sleeved on the opposite ends of the guide rods. A vertical rod is fixedly connected to the bottom side of each collar. A connecting block is fixedly connected to the middle of the outer side wall of both the first and second arc-shaped scrapers. The bottom ends of the vertical rods pass through the top cover and are rotatably connected to the corresponding connecting blocks.

[0011] Furthermore, the top cover has straight grooves equidistantly spaced around its interior, corresponding to the vertical rods, and the vertical rods are all placed inside the corresponding straight grooves. The top of the top cover is rotatably connected to an annular plate, and the annular plate has arc-shaped grooves equidistantly spaced around its interior, and the vertical rods are all placed inside the corresponding arc-shaped grooves. A toothed ring is fixedly fitted on the outer wall of the annular plate.

[0015] The beneficial effects of this invention compared to the prior art are as follows: 1. This invention, through the design of the drive component, realizes the entire process of automatic downward scraping, slag collection, spiral slag discharge, and resetting of the arc-shaped scraper. An electric push rod drives the vertical rod downward, causing the arc-shaped scraper to synchronously scrape away adhering impurities along the inner wall of the coarse filter cylinder. Motor 2 drives the annular plate to rotate, causing the vertical rod to converge towards the center, reducing the diameter and increasing the height of the frustum-shaped scraping ring formed by the first and second arc-shaped scrapers. This ring ultimately adheres to the outer side of the bottom end of the spiral blades, trapping impurities between the scraper and the spiral blades. The spiral blades then continuously rotate, smoothly outputting the collected impurities upward. The entire process is completed while the coarse filter cylinder is continuously rotating, eliminating the need for shutdown and disassembly for cleaning, ensuring the continuity of coarse filtration operations, and significantly improving the processing efficiency and operational stability of the device.

[0016] 2. The first and second arc-shaped scrapers are connected end to end to form a frustum-shaped scraping ring. In the expanded state, it completely fits the inner wall of the coarse filter cylinder. When moving from top to bottom, it can scrape off impurities from all parts of the cylinder wall without any dead corners. After the arc-shaped scrapers converge, they concentrate the scraped impurities between the scraper and the spiral blade. The bottom radius of the spiral blade is designed to gradually increase downward, which matches the shape of the converged scraper. It can smoothly transport the impurities at the bottom upward, avoiding the accumulation of impurities at the bottom of the coarse filter cylinder and causing blockage.

[0017] 3. This invention employs a multi-station rotary fine filtration structure. When one fine filter cartridge becomes clogged, it automatically switches to the next clean fine filter cartridge to continue filtration. Simultaneously, the clogged fine filter cartridge is cleaned by negative pressure adsorption. Filtration and cleaning are carried out simultaneously at different stations, achieving continuous operation of the fine filtration process and improving wastewater treatment efficiency.

[0025] The top of the top cover 9 is symmetrically connected to the water inlet pipe 37 near the middle, and the top of the sewage pipe 10 is connected to the L-shaped pipe 38. The end of the L-shaped pipe 38 away from the sewage pipe 10 passes through the mounting frame 8 and is connected to the sludge collection box 39. The side wall of the reaction tank 1 is fixedly connected to the control cabinet 40. The control cabinet 40 has a built-in programmable controller, which uniformly controls the start and stop, action sequence and rotation cycle of each motor, electric push rod 19, water pump 33 and negative pressure pump 35, so as to realize the fully automatic operation of the equipment.

[0026] The driving assembly includes an electric push rod 19, a guide rod 20, a collar 21, and a vertical rod 22. The electric push rod 19 is fixedly connected to the side wall of the purification cylinder 2, and its output end is fixedly connected to a cross-shaped frame 23. The cross-shaped frame 23 is slidably sleeved on the outer wall of the drain pipe 10. Guide rods 20 are fixedly connected circumferentially at equal intervals to the bottom of the cross-shaped frame 23. A collar 21 is slidably sleeved at the ends of the guide rods 20 that are far apart from each other. Vertical rods 22 are fixedly connected to the bottom side of each collar 21. The arc-shaped scraper 4 and the arc-shaped scraper 5... Connecting blocks are fixedly connected to the middle of the outer side wall. The bottom ends of the vertical rods 22 pass through the top cover 9 and are rotatably connected to the corresponding connecting blocks. The vertical rods 22 and the connecting blocks are connected by a hinge, which ensures that the arc-shaped scraper 1 4 and the arc-shaped scraper 2 5 can adaptively adjust their angles during the gathering and expanding process. The vertical rods 22 are designed in two sections. The bottom end of the upper section has a sliding hole with a spring installed inside. The top end of the lower section is slidably installed inside the sliding hole, which allows for the fine adjustment of the length of the vertical rods 22 during the gathering process of the scraper.

[0027] The top cover 9 has straight grooves equidistantly spaced around its interior, corresponding to the vertical rods 22, and the vertical rods 22 are all placed inside the corresponding straight grooves.

[0028] A mounting base 29 is fixedly connected to the top of the reaction tank 1. A filter disc 30 is rotatably connected inside the mounting base 29. A motor 31 is fixedly connected to the top of the mounting base 29, and its output end extends into the interior of the mounting base 29 and is fixedly connected to the axis of the filter disc 30. Circular grooves are equidistantly opened around the interior of the filter disc 30. Each fine filter cylinder 6 is fixedly installed inside the corresponding circular groove. A drain pipe 32 is connected to the bottom end of the purification cylinder 2. The bottom end of the drain pipe 32 contacts the top end of the filter disc 30 and corresponds to the position of one of the circular grooves. There are 6 fine filter cylinders 6 on the filter disc 30, of which 1 is for filtration, 1 is for cleaning, and 4 are for standby.

[0029] A water pump 33 is fixedly connected inside the mounting bracket 8. The input end of the water pump 33 is located below the filter plate 30 and corresponds to the drain end of the drain pipe 32. An arc-shaped cover 34 is fixedly connected to the input end of the water pump 33. The top of the arc-shaped cover 34 contacts the bottom end of the filter plate 30. The output end of the water pump 33 is connected to the end of the reaction tank 1.

[0030] A negative pressure pump 35 is fixedly connected to the top of one end of the reaction tank 1 near the mounting frame 8. The input end of the negative pressure pump 35 is connected to the negative pressure suction nozzle 7 through a pipe. The negative pressure suction nozzle 7 corresponds to one of the circular grooves, and its bottom end contacts the top end of the filter plate 30. The output end of the negative pressure pump 35 is connected to the collection box 36 through a pipe.

[0031] The working principle of the wastewater treatment device for beverage factories provided by this invention is as follows: In the initial state, the electric push rod 19 is fully extended, and the cross-shaped frame 23 is located at the highest point on the outer wall of the drain pipe 10. Arc-shaped scraper 4 and arc-shaped scraper 5 are located at the highest point inside the coarse filter cylinder 3, in a fully extended state, with their bottom edges contacting the inner wall of the coarse filter cylinder 3. The protruding rods at both ends of arc-shaped scraper 4 are positioned at the initial position of the corresponding mating grooves of arc-shaped scraper 5, and the two are connected end-to-end to form a frustum-shaped scraping ring with the maximum diameter. One of the fine filter cylinders 6 on the filter disc 30 is precisely aligned with the drain pipe 32 at the bottom of the purification cylinder 2, and the other fine filter cylinder 6 is precisely aligned with the negative pressure suction nozzle 7; both the water pump 33 and the negative pressure pump 35 are in a stopped state.

[0032] Beverage production wastewater enters the coarse filter cartridge 3 cavity inside the purification cartridge 2 through two symmetrically arranged inlet pipes 37 at the top of the top cover 9. After receiving the liquid level signal, the control cabinet 40 starts the motor 12. The output end of the motor 12 drives the rotating rod 13 to rotate slowly. The driving gear 15 at the bottom of the rotating rod 13 meshes with the driven gear 16, driving the shaft to rotate rapidly. The speed-changing gear 17 at the top of the shaft meshes with the transmission gear 18 on the outer wall of the sleeve 11, thereby driving the sleeve 11 and the coarse filter cartridge 3 fixedly connected to it to rotate at high speed.

[0033] The centrifugal force generated by the high-speed rotation of the coarse filter cartridge 3 throws large impurities such as fruit peels and debris in the wastewater toward the cartridge wall and intercepts them. The filtered wastewater passes through the filter holes of the coarse filter cartridge 3 and enters the annular cavity between the purification cartridge 2 and the coarse filter cartridge 3.

[0034] After the coarse filter cartridge 3 has been running for a preset time, the control cabinet 40 activates the electric push rod 19 to retract. The electric push rod 19 drives the cross-shaped frame 23 to slide downwards along the outer wall of the drain pipe 10, thereby driving the four guide rods 20 to move downwards synchronously. The guide rods 20 transmit the downward force to the arc-shaped scraper 4 and the arc-shaped scraper 5 through the collar 21 and the vertical rod 22, causing them to move downwards synchronously along the inner wall of the coarse filter cartridge 3, scraping away large pieces of impurities adhering to the cartridge wall. During this process, the vertical rod 22 simultaneously slides in the straight groove of the top cover 9 and the arc-shaped groove 25 of the annular plate 24. Since the annular plate 24 does not rotate at this time, the vertical rod 22 only moves vertically downwards along the straight groove, while the arc-shaped scraper 4 and the arc-shaped scraper 5 remain in an extended state.

[0035] When the first arc-shaped scraper 4 and the second arc-shaped scraper 5 move down to the bottom of the coarse filter cylinder 3, the electric push rod 19 stops retracting, and the control cabinet 40 starts the second motor 27 to rotate forward. The second motor 27 drives the annular plate 24 to rotate through the meshing of the gear 28 and the gear ring 26. The arc-shaped groove 25 inside the annular plate 24 rotates with it, generating a radially inward squeezing force on the vertical rods 22, forcing the four vertical rods 22 to converge towards the center along the straight groove of the top cover 9. The collar 21 at the top of the vertical rod 22 slides synchronously along the axial direction of the guide rod 20 to ensure the stability of the movement of the vertical rod 22. The bottom of the vertical rod 22 drives the corresponding arc-shaped scraper 4 and the second arc-shaped scraper 5 to move closer to each other: the protruding rods at both ends of the arc-shaped scraper 4 slide along the matching groove trajectory inside the arc-shaped scraper 5, so that the diameter of the frustum formed by the two gradually decreases and the height gradually increases.

[0036] When the annular plate 24 rotates to the preset angle, the arc-shaped scraper 1 4 and the arc-shaped scraper 2 5 completely converge. With the retraction of the electric push rod 19, the inner sidewalls of the arc-shaped scraper 1 4 and the arc-shaped scraper 2 5 are attached to the outer side of the bottom end of the spiral blade 14, the top end contacts the outer wall of the bottom end of the sewage pipe 10, and the bottom end contacts the side wall of the bottom end of the coarse filter cylinder 3, thus surrounding the scraped impurities in the space between the scraper and the spiral blade 14.

[0037] After the arc-shaped scraper 4 and arc-shaped scraper 5 have gathered the impurities, the motor 12 continues to rotate, driving the spiral blades 14 on the outer wall of the rotating rod 13 to continue rotating. Because the bottom radius of the spiral blades 14 is designed to gradually increase downwards, the impurities gathered at the bottom can be smoothly transported upwards and discharged into the collection box 39 through the drain pipe 10 and the L-shaped pipe 38 for centralized collection.

[0038] After slag discharge is completed, motor 27 remains stopped, and electric push rod 19 extends and resets, driving the cross-shaped frame 23, vertical rod 22, and the converging arc-shaped scrapers 4 and 5 upwards synchronously. When arc-shaped scrapers 4 and 5 return to the highest point inside the coarse filter cylinder 3, electric push rod 19 stops extending, motor 27 reverses, and drives the annular plate 24 to rotate in the opposite direction. The arc-shaped groove 25 generates a radially outward thrust on the vertical rod 22, causing the vertical rod 22 to move outward along the straight groove, driving arc-shaped scrapers 4 and 5 to spread outwards and return to their initial expanded state, ready for the next slag scraping cycle.

[0039] After coarse filtration, the wastewater flows out from the drain pipe 32 at the bottom of the purification cylinder 2 and enters the fine filter cylinder 6 aligned with it on the filter disc 30. The control cabinet 40 starts the water pump 33, and the arc-shaped cover 34 at the input end of the water pump 33 creates a negative pressure below the fine filter cylinder 6, drawing out the wastewater that has passed through the filter holes of the fine filter cylinder 6 and sending it into the reaction tank 1 through the output end of the water pump 33. The fine filter cylinder 6 intercepts fine suspended solids, pectin particles, and colloidal substances in the wastewater, further purifying the water quality.

[0040] When the fine filter cartridge 6 has been running for a preset time, the control cabinet 40 starts motor 31, which drives the filter disc 30 to rotate by a fixed angle equal to the angle between two adjacent fine filter cartridges 6, aligning the next clean fine filter cartridge 6 with the drain pipe 32 to continue the filtration process. When the fine filter cartridge 6, after intercepting impurities, rotates to a position aligned with the negative pressure suction nozzle 7, the control cabinet 40 starts the negative pressure pump 35. This generates a strong negative pressure inside the fine filter cartridge 6 through the negative pressure suction nozzle 7, sucking away all the fine impurities intercepted on the inner wall of the filter cartridge and transporting them through pipelines to the collection box 36 for centralized processing. After cleaning, the negative pressure pump 35 stops running, and the fine filter cartridge 6 resumes its filtration capacity, awaiting the next rotation. Through the intermittent rotation of the filter disc 30, continuous and uninterrupted operation of the fine filtration process is achieved.

[0041] After two stages of pretreatment, coarse filtration and fine filtration, the wastewater enters reaction tank 1. The dosing mechanism in the upper middle part of reaction tank 1 automatically adds flocculants, pH adjusters and other agents according to the wastewater quality, so that the colloidal substances and dissolved pollutants in the wastewater undergo a coagulation reaction. The wastewater after the reaction enters subsequent sedimentation, biological treatment and other units, and finally meets the discharge standards or is reused.
