Description

Technical Field

[0001] This utility model relates to the field of brewing wastewater filtration technology, and in particular to a filtration device for brewing wastewater treatment. Background Technology

[0002] Water is an essential element in the brewing process. Therefore, in the modern brewing industry, companies often attach great importance to the selection of water sources and the reuse of brewing wastewater. For example, most companies choose to filter the wastewater used for washing raw materials and then use it as cooling water, which reduces costs to some extent. However, most existing filtration devices have a simple structure, often just a simple filter screen. After prolonged use, the filter screen is easily clogged by debris, and the filter screen is not easy to replace, thus affecting the filtration effect of the device and further impacting the reuse of the washing wastewater.

[0003] In existing patent CN217988487U, a non-clogging filtration device for treating brewing wastewater is disclosed. A cleaning component cleans the filter layer after or during each filtration process, preventing impurities from clogging the filter layer and affecting filtration efficiency. Simultaneously, the impurities processed by the cleaning component fall into the filter residue collection assembly for subsequent centralized treatment, improving processing efficiency. The brush head moves up and down through the cooperation of a first motor, lead screw, and moving block, thus cleaning the entire filter layer. A second rotating motor rotates the brush head, resulting in better and more thorough cleaning of the filter residue. It should be noted that because the rotating brush head may cause filter residue to scatter, some may fall to the bottom of the filter housing and not into the collection box. After removing the filter housing, the filter residue at the bottom of the filter housing can be manually swept out through the filter residue outlet.

[0004] In the existing methods described above, the rotating brush head causes filter residue to scatter throughout the filter chamber. After cleaning the filter layer, personnel are required to clean the inside of the filter chamber, which requires a lot of manpower and time and is inconvenient to use. Utility Model Content

[0005] The purpose of this utility model is to provide a filtration device for treating brewing wastewater, which solves the problems in the prior art where the rotating brush head causes filter residue to scatter all over the filter box, and after cleaning the filter layer, personnel are still required to clean the inside of the filter box, which requires a lot of manpower and time and is inconvenient to use.

[0006] To achieve the above objectives, this utility model employs a filtration device for treating brewing wastewater, comprising a filter box, a filter layer, an inlet, an outlet, and a cleaning component. The filter layer is fixedly connected to the filter box and located within the filter box. Both the inlet and the outlet are connected to the filter box. The cleaning component includes a movable plate, multiple unblocking rods, a connecting rod, a lifting unit, and a scraping unit. The movable plate is slidably connected to the filter box and located within the filter box. The multiple unblocking rods are fixedly connected to the movable plate and located below it. The connecting rod is slidably connected to the filter box and penetrates through it. One end of the connecting rod is fixedly connected to the movable plate. The lifting unit is fixedly positioned above the filter box and is also connected to the other end of the connecting rod. The filter box has a discharge hole, and the scraping unit is mounted on the filter box.

[0007] The lifting unit includes a bracket, a motor, a threaded rod, and a sleeve. The bracket is fixedly connected to the filter housing and located above the filter housing.

[0011] This utility model discloses a filtration device for treating brewing wastewater. Brewing wastewater is poured into the filter housing through the inlet, passes through the filter layer, and is then discharged through the outlet. To clean the filter layer, the discharge hole is first opened, and then the scraping component pushes out the filter residue retained on the filter layer, achieving initial cleaning. Then, the lifting unit is activated, causing the connecting rod to slide down the filter housing. The movable plate is moved downwards within the filter housing, and subsequently, multiple unblocking rods below the movable plate insert into the filter layer to clear blockages. The filter residue falls to the bottom of the filter housing and is then discharged through the outlet. This method facilitates cleaning of the filter layer, prevents filter residue from accumulating inside the filter housing, saves manpower and time, and is convenient to use.

Detailed Implementation

[0019] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0020] Please see Figures 1-5 This utility model provides a filtration device for treating brewing wastewater: it includes a filter box 101, a filter layer 102, an inlet 103, an outlet 104, and a cleaning component. The filter layer 102 is fixedly connected to the filter box 101 and located inside the filter box 101. The inlet 103 and the outlet 104 are both connected to the filter box 101. The cleaning component includes a movable plate 105, multiple unclogging rods 106, a connecting rod 107, a lifting unit, and a scraping unit. The movable plate 105 is slidably connected to the filter box 101 and located inside the filter box 101. Inside the filter housing 101, multiple unblocking rods 106 are fixedly connected to the movable plate 105 and are all located below the movable plate 105. The connecting rod 107 is slidably connected to the filter housing 101 and passes through the filter housing 101. One end of the connecting rod 107 is fixedly connected to the movable plate 105. The lifting unit is fixedly installed above the filter housing 101. The lifting unit is also connected to the other end of the connecting rod 107. The filter housing 101 has a discharge hole 120. The scraping unit is installed on the filter housing 101.

[0021] In this embodiment, brewing wastewater is poured into the filter housing 101 through the inlet 103. The wastewater is filtered through the filter layer 102 and then discharged through the outlet 104. To clean the filter layer 102, the outlet 120 is opened first, and then the scraping assembly pushes the filter residue retained on the filter layer 102 out of the outlet 120, achieving initial cleaning of the filter layer 102. Then, the lifting unit is activated to drive the connecting rod 107 in the filter housing 101. As the filter slides up and down, the movable plate 105 is moved down inside the filter housing 101. Then, the multiple unblocking rods 106 below the movable plate 105 are inserted into the filter layer 102 to clear the blockage. The filter residue falls to the bottom of the filter housing 101 and is then discharged through the outlet 104. By using the above method, it is easy to clean the filter layer 102, avoids filter residue from accumulating inside the filter housing 101, saves manpower and time, and is convenient to use.

[0022] Furthermore, the lifting unit includes a bracket 108, a motor 109, a threaded rod 110, and a sleeve 111. The bracket 108 is fixedly connected to the filter housing 101 and is located above the filter housing 101. The motor 109 is fixedly connected to the bracket 108 and is located above the bracket 108. The threaded rod 110 is connected to the output end of the motor 109 and is located inside the bracket 108. The sleeve 111 is sleeved on the outside of the threaded rod 110 and is threadedly engaged with the threaded rod 110. The sleeve 111 is also fixedly connected to the connecting rod 107 and is located at the end of the connecting rod 107 away from the movable plate 105.

[0023] In this embodiment, during use, by activating the motor 109 on the bracket 108, the output end of the motor 109 drives the threaded rod 110 to rotate. Since the sleeve 111 is threadedly engaged with the threaded rod 110, and the connecting rod 107 guides the sleeve 111, the sleeve 111 will then move downward on the threaded rod 110. At the same time, the sleeve 111 will drive the movable plate 105 to move downward within the filter box 101 via the connecting rod 107. Subsequently, the multiple unblocking rods 106 on the movable plate 105 will unblock the through holes of the filter layer 102.

[0024] Furthermore, the lifting unit also includes a limiting block 112, which is fixedly connected to the threaded rod 110 and located at the end of the threaded rod 110 away from the output end of the motor 109.

[0025] In this embodiment, by providing the limiting block 112 at the lower end of the threaded rod 110, the movement range of the sleeve 111 is limited, thereby preventing the sleeve 111 from disengaging from the threaded rod 110.

[0026] Furthermore, the scraping unit includes an electric telescopic rod 113, a cleaning plate 114, a torsion spring 115, a sealing plate 116, and a fixing member. The electric telescopic rod 113 is fixedly mounted on the filter housing 101. The cleaning plate 114 is connected to the output end of the electric telescopic rod 113 and is located inside the filter housing 101. The sealing plate 116 is rotatably connected to the filter housing 101 and is located inside the discharge hole 120. The two ends of the torsion spring 115 are respectively connected to the sealing plate 116 and the filter housing 101. The fixing components are fixedly connected to the filter housing 101 and the sealing plate 116 respectively. The fixing components include a movable stop 117, a first magnetic block 118, and a second magnetic block 119. The movable stop 117 is rotatably connected to the filter housing 101 and is located on the outer side wall of the sealing plate 116. The first magnetic block 118 is fixedly connected to the movable stop, and the second magnetic block 119 is fixedly connected to the sealing plate 116. The second magnetic block 119 and the first magnetic block 118 are magnetically attracted to each other.

[0027] In this embodiment, when cleaning the filter layer 102, the movable stop 117 is first rotated, and the first magnetic block 118 on the movable stop 117 separates from the second magnetic block 119 on the sealing plate 116. Then, under the action of the torsion spring 115, the sealing plate 116 rotates outward in the discharge hole 120, and the discharge hole 120 is opened. Then, the electric telescopic rod 113 is activated to drive the cleaning plate 114 to move horizontally above the filter layer 102, pushing the filter residue retained above the filter layer 102 toward the discharge hole 120, so as to perform preliminary cleaning of the filter layer 102. Then, the movable plate 105 is controlled to move downward, so that multiple unblocking rods 106 are inserted into the filter layer 102 to unclog the blocked area of ​​the filter layer 102.

[0028] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model.
