Description

Technical Field

[0001] This utility model relates to the field of waste liquid recycling technology, specifically a recycling box for cleaning liquid in a dairy processing workshop. Background Technology

[0002] The cleaning solution used in dairy processing workshops may contain various impurities during use. These impurities mainly come from dairy product residues, the components of the cleaning solution itself, and scale, etc.

[0003] Among them, dairy product residues include: protein: casein, whey protein, etc. in milk can easily adhere to the surface of equipment, forming stubborn dirt.

[0004] Fat: Milk fat tends to solidify at low temperatures and adheres to the inner walls of pipes or containers.

[0005] Lactose: Sugar residues may breed microorganisms or form a caramelized layer (under high temperature conditions).

[0006] Minerals: Minerals such as calcium and magnesium (from milk) may react with cleaning agents to form precipitates.

[0007] Cleaning agent ingredients:

[0008] Alkaline or acidic components: such as sodium hydroxide (NaOH), nitric acid (HNO3), and other strong acid and strong base residues.

[0009] Surfactants: Emulsifiers or detergents that were not completely rinsed out.

[0010] Chelating agents: such as EDTA, citrate (used for water softening, but may leave residues).

[0011] Disinfectants: residues of oxidizing agents such as peracetic acid and sodium hypochlorite.

[0012] Scale and water-related impurities:

[0013] Calcium and magnesium deposits: calcium carbonate, calcium sulfate, etc. in hard water.

[0014] Rust: Iron oxides produced by corrosion of pipes or equipment

[0015] Suspended particles: sediment, colloids, etc. in water.

[0016] When the aforementioned impurities are transferred to the recycling bin for collection, they generally need to be graded within the recycling bin to prevent secondary pollution. To ensure the classified processing of different impurities, existing recycling bins often employ multi-stage filtration in their internal structural design, such as: a first-layer coarse filtration, a second-layer adsorption filtration, and a third-layer ion exchange resin filtration. However, the existing structural design makes it inconvenient to easily install and remove each filter screen for these different filtration layers. Moreover, the first layer, which performs coarse filtration, is subject to the impact of different types of particulate impurities. Simple static filtration can easily cause problems such as clogging of the mesh due to insufficient filtration intensity.

[0017] Therefore, in view of the above-mentioned problems, this technical solution designs a cleaning solution recovery box for dairy processing workshops. Utility Model Content

[0018] The purpose of this invention is to provide a cleaning solution recovery box for dairy processing workshops to solve the problems mentioned in the background art.

[0019] To achieve the above objectives, this utility model provides the following technical solution:

[0020] A dairy processing workshop cleaning fluid recovery tank includes an inverted cylindrical stepped cleaning fluid recovery tank. The tank contains stainless steel screens, activated carbon screens, and resin column layers installed at intervals from top to bottom for multi-stage impurity filtration of the incoming dairy processing workshop cleaning fluid. The stainless steel screens, activated carbon screens, and resin column layers are all detachably installed on the tank wall. The diameters of the stainless steel screens, activated carbon screens, and resin column layers decrease sequentially to ensure that the resin column layers can pass through the stainless steel screens and activated carbon screens for vertical transfer, and the activated carbon screens can pass through the stainless steel screens for vertical transfer. The stainless steel screens are rotatably positioned and connected to the tank wall, while the activated carbon screens and resin column layers are longitudinally clamped and positioned to the tank wall.

[0021] Referring to Figure 1-2, the stainless steel screen includes a filter screen plate. A mesh frame is installed around the outer periphery of the filter screen plate. The filter screen plate is used for coarse filtration of the input dairy product cleaning solution. A positioning frame is rotatably installed on the inner wall of the cleaning solution recovery tank corresponding to the outer periphery of the filter screen plate. A support plate is installed radially extending from the lower inner side of the positioning frame. The width of the support plate is used to support the mesh frame, thereby placing the filter screen plate in the middle of the positioning frame. An external toothed ring is installed around the outer periphery of the positioning frame. One side of the external toothed ring is engaged with a drive tooth. A servo motor is connected to the bottom of the drive tooth. The drive tooth and the servo motor are placed in a motor housing fixed on the outer wall of the cleaning solution recovery tank. By starting the servo motor, the drive tooth is driven to rotate, which in turn drives the external toothed ring to control the rotation of the positioning frame, thereby causing the filter screen plate to rotate and filter the cleaning solution.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] The servo motor drives the stainless steel screen to rotate, generating centrifugal force to effectively break up protein clots and fat deposits, thus improving the coarse filtration efficiency.

[0024] By using a screw clamping mechanism to press the activated carbon mesh and resin column mesh together, a single person can quickly disassemble and assemble the equipment, thus improving maintenance efficiency.

[0025] The three-stage through-flow layout consists of a filter layer with decreasing diameter: stainless steel screen > activated carbon screen > resin column screen, forming a vertical through-flow channel to avoid structural interference during layer disassembly. Attached Figure Description

[0035] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0036] Please see Figure 1 A dairy processing workshop cleaning fluid recovery tank includes an inverted cylindrical stepped cleaning fluid recovery tank 10. The tank 10 contains stainless steel screens 14, activated carbon screens 15, and resin column meshes 16 installed at intervals from top to bottom for multi-stage impurity filtration of the incoming dairy processing workshop cleaning fluid. The stainless steel screens 14, activated carbon screens 15, and resin column meshes 16 are all detachably installed on the tank wall of the cleaning fluid recovery tank 10. The diameters of the stainless steel screens 14, activated carbon screens 15, and resin column meshes 16 decrease sequentially to ensure that the resin column meshes 16 can pass through the stainless steel screens 14 and 15 for vertical movement, and the activated carbon screens 15 can pass through the stainless steel screens 14 for vertical movement. The stainless steel screens 14 are rotatably positioned and connected to the tank wall of the cleaning fluid recovery tank 10, and the activated carbon screens 15 and resin column meshes 16 are longitudinally clamped and positioned and connected to the tank wall of the cleaning fluid recovery tank 10.

[0037] See Figures 1-3The stainless steel screen 14 includes a filter screen plate 17. A mesh frame 18 is installed around the filter screen plate 17. The filter screen plate 17 is used to coarsely filter the input dairy product cleaning liquid. A positioning frame 20 is rotatably installed on the inner wall of the cleaning liquid recovery tank 10 corresponding to the outer side of the filter screen plate 17. A support plate is installed radially extending from the lower inner side of the positioning frame 20. The width of the support plate is used to support the mesh frame 18, thereby placing the filter screen plate 17 in the middle of the positioning frame 20. An external toothed ring 22 is installed around the outer side of the positioning frame 20. One side of the external toothed ring 22 is engaged with an active tooth 24. The bottom of the active tooth 24 is connected to a servo motor 25. The active tooth 24 and the servo motor 25 are placed in a motor housing 23 fixed on the outer wall of the cleaning liquid recovery tank 10. By starting the servo motor 25, the active tooth 24 is driven to rotate, which in turn drives the external toothed ring 22 to control the rotation of the positioning frame 20, thereby driving the filter screen plate 17 to rotate and filter the cleaning liquid.

[0038] Specifically, a plurality of positioning holes 21 are provided at equal intervals in a ring on the upper side of the support plate. Positioning pins 19 are installed at the bottom of the mesh frame 18 corresponding to the positioning holes 21. By inserting the positioning pins 19 into the corresponding positioning holes 21, the filter screen 17 is stably installed inside the positioning frame 20, so that it can stably follow the positioning frame 20 to rotate and filter.

[0039] See Figure 1 , Figures 4-5 Both the activated carbon mesh 15 and the resin column mesh 16 have mesh frames 18 of the same width fixedly installed on their outer circumferential walls. The cleaning liquid recovery tank 10 corresponding to the activated carbon mesh 15 and the resin column mesh 16 has the same structure. Taking the resin column mesh 16 as an example, a support ring 27 is installed on the wall of the cleaning liquid recovery tank 10 corresponding to the outer mesh frame 18 of the resin column mesh 16. The support ring 27 is used to support and limit the mesh frame 18. At the same time, multiple sets of positioning pressure members are arranged in a ring in the wall of the cleaning liquid recovery tank 10 above the support ring 27. The positioning pressure members move radially along the wall of the cleaning liquid recovery tank 10 and longitudinally press the top of the mesh frame 18 on the support ring 27.

[0040] The positioning pressure component includes an internal threaded hole 31 opened in the wall of the cleaning fluid recovery tank 10. A screw 30 is threadedly connected inside the internal threaded hole 31. The outer end of the screw 30 extends to the outside of the cleaning fluid recovery tank 10 and is connected to a handle 29. The inner end is rotatably connected to an upper pressure plate 28. A buffer pad is provided at the bottom of the upper pressure plate 28. By rotating the handle 29, the screw 30 is controlled to move radially, and then the bottom of the upper pressure plate 28 is driven to contact and press or separate from the top of the mesh frame 18.

[0041] The connection between the screw 30 and the upper pressure plate 28 adopts a limiting rotation connection, that is, a T-shaped rotating block 32 is installed at the end of the screw 30, and a T-shaped rotating hole 33 is opened in the upper pressure plate 28 corresponding to the T-shaped rotating block 32. The T-shaped rotating block 32 and the T-shaped rotating hole 33 are connected in a limiting rotation, thereby ensuring that when the screw 30 rotates and moves radially, the transfer of the upper pressure plate 28 can be stably controlled.

[0042] In this embodiment of the invention, the cleaning fluid of the dairy workshop to be recycled is fed into the cleaning fluid recycling tank 10 along the top of the cleaning fluid recycling tank 10. The top of the cleaning fluid recycling tank 10 is equipped with a tank cover 11, and the bottom is evenly equipped with brackets 12 for stable support.

[0043] A sealing ring is provided at the position where the upper pressure plate 28 comes into contact with the wall of the cleaning fluid recovery tank 10 to prevent liquid from leaking outwards;

[0044] The bottom of the cleaning fluid recovery tank 10 is provided with a cone-shaped sedimentation chamber, and the bottom of the sedimentation chamber is connected to the outlet 13, through which the filtered and precipitated cleaning fluid is output.

[0045] In one embodiment of the present invention, the activated carbon mesh 15 and the resin column mesh 16 can smoothly pass through the area where the support ring 27 is installed when moving vertically. At the same time, the width of the activated carbon mesh 15 and the resin column mesh 16 plus the width of their mesh frames 18 is smaller than the size of the hole after the inner support plate of the positioning frame 20 is extended, so as to keep the activated carbon mesh 15 and the resin column mesh 16 moving through the inside of the positioning frame 20.

[0046] As a preferred embodiment of the present invention, the activated carbon mesh 15 can also be replaced with a diatomaceous earth filter mesh to adsorb fat and organic residues in the cleaning solution. Meanwhile, the resin column mesh 16 is composed of uniformly arranged resin columns to remove calcium and magnesium ions and reduce scale.

[0047] The sedimentation chamber at the bottom of the cleaning fluid recovery tank 10 is used to collect sediment, such as protein flocs and scale.

[0048] It should be noted that all materials used in this technical solution are corrosion-resistant to ensure a certain degree of resistance after contact with the cleaning solution.

[0049] The working principle of this utility model is as follows: In the idle position of this device, all the aforementioned driving components (representing power elements, electrical devices, and compatible power supplies) are connected via wires. The electrical connections are completed in sequence between the working components. The detailed connection methods are well-known in the field. The following mainly describes the working principle and process, without further explanation of the electrical control.

[0050] Liquid inlet coarse filtration stage: The cleaning liquid enters from the top of the tank and impacts the rotating stainless steel screen 14;

[0051] Servo motor 25 drives active gear 24 to drive external gear ring 22, so that filter screen plate 17 centrifuges and filters at 15 rpm to separate particles >500μm.

[0052] Positioning pin 19 and positioning hole 21 ensure stable operation of the screen.

[0053] Adsorption and filtration stage: The liquid flows through activated carbon mesh 15, adsorbing fats, residual disinfectants and pigments;

[0054] The mesh frame 18 is supported by the support ring 27. The rotating handle 29 tightens the screw 30 to push the upper pressure plate 28 down, and vertical pressing is achieved through the cooperation of the T-shaped rotating block 32 and the T-shaped rotating hole 33.

[0055] Ion exchange stage: Liquid penetrates the resin column mesh 16, removing calcium and magnesium ions with a descaling rate of ≥95%;

[0056] The same clamping mechanism enables rapid fixation of the resin layer.

[0057] Sedimentation and discharge stage: The treated liquid enters the conical sedimentation tank, where protein flocs and scale are deposited;

[0058] Clean liquid is discharged from outlet 13, and sediment is cleaned regularly.

[0059] It should be understood that in this application, all rotating, sliding, meshing, belt-driven and other moving parts are well lubricated and not prone to slippage or wear, and each part is provided with a corresponding protective shell. However, in the accompanying drawings of this application, the connection state of each moving part is not shown. It should also be understood that all parts in this application are made of metal or plastic materials with suitable strength in the relevant field to ensure that their structural rigidity meets the actual requirements.

[0060] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
