Description

Technical Field

[0001] This utility model relates to the field of conveyor technology, specifically to a fabric dyeing and printing wastewater recycling device. Background Technology

[0002] Manufacturing powder metallurgy parts requires an oil impregnation process. This process improves the wear resistance, extends the service life, and reduces operating noise. The manufacturing process involves collecting parts in a frame, followed by oil impregnation. This concentrated stacking of workpieces makes them highly susceptible to scratches during operation, leading to a decrease in yield.

[0003] Currently, a Chinese patent with publication number CN85202535U has been found, disclosing a vacuum impregnation apparatus. The key technical points of the apparatus are: it consists of a vacuum chamber, a top cover that seals the vacuum chamber, an air extraction valve connected to the top cover via a pipe, and a mechanical pump connected to the air extraction valve via a pipe; the system is also connected to a reservoir for holding impregnation liquid, which is connected to the vacuum chamber via a pipe and a filling valve; and a pressure osmosis device is installed between the mechanical pump and the air extraction valve, which consists of a nitrogen tank, a T-type three-way valve, a pressure gauge valve connected between the three-way valve and the air extraction valve, and a pressure gauge; a mesh sample container for holding the impregnated material is installed inside the vacuum chamber.

[0004] The above method involves placing the parts in a mesh sample container, then placing the mesh sample container in a vacuum chamber, and finally immersing the bearing-containing parts in the mesh sample container in an impregnation solution within the vacuum chamber. However, this method involves immersing the entire part in the impregnation solution, which can easily lead to contamination or corrosion of the housing within the part. Furthermore, a large amount of impregnation solution is carried away during removal, resulting in waste of the impregnation solution. Utility Model Content

[0011] As a preferred embodiment of this application, an exhaust port is installed on the top of the filter box.

[0012] As a preferred embodiment of this application, an inspection port is provided on the lower cavity of the filter box.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This application utilizes a filter permeation tank to effectively filter out solid waste and larger particulate impurities from wastewater, improving the efficiency and water quality of subsequent treatment.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figure 1-5 As shown, the filter box 1 of this utility model is provided with a filter permeation tank 2 inside. The filter box 1 is provided with a waste outlet 12. The filter permeation tank 2, which is connected to the waste outlet 12, is provided inside the filter box 1. The tank is connected to the inside of the filter box 1 through the permeation holes on its side wall and discharges the filtered liquid through the discharge port 14. At the bottom of the filter permeation tank 2, a secondary filter plate 3 and a liquid storage baffle 4 are arranged in sequence. The liquid storage baffle 4 divides the filter box 1 into two independent cavities. The upper cavity is used to contain the filtered wastewater and discharge the treated liquid, while the lower cavity is used to house the rotating motor 5.

[0024] This application uses a filter permeation tank 2 inside the filter box 1 to perform preliminary filtration of dyeing and printing wastewater. Solid impurities in the wastewater are trapped in the filter permeation tank 2. The secondary filter plate 3 further filters the wastewater, improving the filtration effect. The rotating motor 5 drives the filter permeation screen and the secondary filter plate 3 to rotate synchronously, making it difficult for impurities to accumulate during the filtration process. At the same time, the liquid storage baffle 4 divides the filter box 1 into two independent upper and lower chambers, which facilitates the step-by-step processing of the device. The filter box 1 can be a stainless steel filter box 1 with a volume selected according to the wastewater treatment volume. The rotating motor 5 can be a Y-series three-phase asynchronous motor. The power of the rotating motor 5 is proportional to the wastewater treatment volume and the equipment size of the filter box 1.

[0025] In actual operation, the filtration rate is calculated based on the wastewater flow rate and the filter area, as follows:

[0026]

[0027] Where υ is the filtration velocity, Q is the wastewater flow rate, and Α is the filtration area.

[0028] Calculate the rotational torque based on the motor power and speed:

[0029]

[0030] Where T is torque, P is motor power, and ω is angular velocity.

[0031] At the bottom of the filter box 1, below the liquid storage baffle 4, a rotating motor 5 is installed. The rotating rod 51 of the rotating motor 5 passes through the liquid storage baffle 4 and is fixedly connected to the chip collection cylinder 33 on the secondary filter plate 3 to drive the secondary filter plate 3 to rotate. The secondary filter plate 3 is fixed to the filter permeation tank 2 by a linkage rod 6 to drive the filter permeation tank 2 and the chip collection cylinder 33 to rotate synchronously. Driven by the motor, the filter permeation tank 2 can rotate, thereby enhancing the flowability of wastewater in the filtration process and improving the filtration efficiency. In this application, a detachable chip collection cylinder 33 is installed on the rotating bearing 32 at the bottom of the secondary filter plate 3. After the filter cake settles to the bottom under the action of centrifugal force and gravity, it will be collected by the chip collection cylinder 33. This design not only facilitates the cleaning of the filter cake, but also prevents the filter cake from re-entering the filtered liquid, ensuring the stability of the filtration effect.

[0032] This application more clearly demonstrates the structural layout of the filter box 1 and the relationship between its components, while also highlighting the linkage function between the rotating motor 5 and the filter permeation tank 2.

[0033] The filter permeation tank 2 includes a transmission base 21 fixed to the rotating rod 51. A filter tube 22 is threadedly connected to the transmission base 21. The filter permeation tank is fixedly connected to the rotating rod 51 via the transmission base 21. The filter tube 22 is threadedly connected to the transmission base 21, facilitating the disassembly and replacement of the filter tube 22. The filter tube 22 can be made of PP or stainless steel, and the thread specification is determined according to actual needs, while ensuring the stable rotation of the filter permeation tank 2. The connection strength is calculated based on the thread parameters of the filter tube 22.

[0034]

[0035] in, F For connection strength, P d represents the preload force, and d represents the thread diameter.

[0036] The secondary filter plate 3 is arranged in a downward inclined funnel shape facing the liquid storage baffle 4, which increases the contact area between wastewater and the filter plate and improves the filtration efficiency. The funnel-shaped design facilitates the collection and discharge of wastewater. The secondary filter plate 3 can be made of stainless steel or polymer material.

[0037] Calculate the filtration time based on the funnel angle and wastewater flow rate:

[0038]

[0039] Where t is the filtration time, V is the wastewater volume, and Q is the flow rate. θ The angle of the funnel.

[0040] The secondary filter plate 3 includes a filter element 31 surrounding the inner wall of the filter box 1. The filter element 31 is arranged in a funnel-shaped ring. This structure increases the contact area between the wastewater and the filter element 31, and guides the wastewater to flow along the surface of the filter element 31. During the flow process, the filter residue is more easily subjected to centrifugal force and gravity and settles to the bottom, further improving the efficiency of filter residue deposition.

[0041] The top surface of the filter element 31 receives the wastewater treated by the filter box 1 and performs secondary filtration. A rotating bearing 32 is provided at the bottom of the filter element, and the rotating bearing 32 is detachably connected to the chip collection cylinder 33. The filter element 31 of the secondary filter plate 3 is arranged in a funnel-shaped ring. After the wastewater passes through the filter element 31, it undergoes secondary filtration. The chip collection cylinder 33 installed on the rotating bearing 32 is used to collect the filtered impurities for easy cleaning. The filter element 31 can be made of porous ceramic or stainless steel sintered mesh. When the secondary filter plate 3 and the filter permeation tank 2 rotate in this application, the solid impurities (filter residue) in the wastewater will be subjected to centrifugal force. The direction of the centrifugal force is from the center of rotation outward, so the filter residue will be pushed towards the filter permeation tank 2 and... The inner wall of the secondary filter plate 3, along with the fluid dynamics effect generated by the rotation, further propels the filter cake to the bottom. This synergistic effect of gravity and fluid dynamics causes relative motion between the wastewater and the filter cake during rotation, generating shear force. This shear force helps to separate the filter cake from the main body of wastewater and push it to the bottom. Rotation also prevents the filter cake from accumulating on the filter surface, reducing filtration resistance and improving filtration efficiency. In summary, the rotation of the secondary filter plate 3 and the filter permeation tank 2, through the synergistic effect of centrifugal force, gravity, fluid dynamics, shear force, and the funnel-shaped annular structure, achieves effective deposition of the filter cake at the bottom, thereby improving filtration efficiency and reducing the interference of the filter cake on the filtration process.

[0042] The filtration efficiency is calculated based on the filtration area of ​​filter element 31 and the wastewater flow rate:

[0043]

[0044] Where η is the filtration efficiency, A is the filtration area, ΔP is the pressure difference, and Q is the flow rate.

[0045] The filter element 31 is any one of a multi-layer composite filter plate, an activated carbon filter plate, a fiber ball filter plate, or a plate and frame filter plate. The appropriate filter plate is selected according to the wastewater composition and treatment requirements. This application aims to achieve efficient filtration of wastewater.

[0046] As a preferred embodiment of this application, an exhaust port 11 is installed on the top of the filter box 1. The exhaust port 11 can be made of stainless steel or aluminum alloy. The size of the exhaust port 11 is calculated based on the amount of gas generated in the filter box 1.

[0047] Where A_exhaust is the area of ​​exhaust port 11, Q_gas is the gas flow rate, and v_gas is the gas velocity. Therefore, the size of exhaust port 11 is 1 / 12 to 1 / 16 of the cross-sectional area of ​​the top of the filter box 1.

[0048] An inspection port 13 is provided on the lower cavity of the filter box 1. This inspection port 13 can also serve as a drain outlet and facilitates the cleaning of filter residue on the filter permeation tank 2 and the secondary filter plate 3 by the staff. The cleaning principle is as follows:

[0049] By adopting the above technical solution and regularly checking the operating status of the rotating motor 5, its normal operation can be ensured.

[0050] Disassemble and clean the chip collection cylinder 33 regularly to remove collected impurities and prevent clogging.

[0051] If the filter tube 22 needs to be replaced, the threaded connection allows for quick disassembly and replacement of the new filter tube 22.

[0052] Regularly check the condition of filter element 31. If it is damaged or clogged, replace or clean it in time to efficiently treat dyeing and printing wastewater, realize the recycling of wastewater, and reduce the maintenance cost and operation difficulty of the equipment.

[0053] like Figure 3 As shown, in actual operation, the top of the filter box 1 is designed to be openable (this is prior art) so that the filter permeation tank 2 and the chip collection cylinder 33 can be manually removed from the filter box for cleaning of waste residue. It should be noted that the bottom of the chip collection cylinder 33 in this application is connected to the rotating rod 51 by a bottom-embedded snap-fit ​​method (prior art), which can drive the chip collection cylinder 33 to rotate. Since the linkage rod 6 provided on the top of the chip collection cylinder 33 is fixedly connected to the transmission chassis 21 (preferably by welding), it drives the transmission chassis 21 to rotate synchronously. In this application, the threads of the filter tube 22 and the transmission chassis 21 are consistent with the rotation direction of the rotating motor 5 to ensure that the filter tube 22 and the transmission chassis 21 always maintain a tight connection during operation.

[0054] like Figure 4 As shown, in another supplementary embodiment, the linkage rod 6 extends upward from the top cover of the filter box 1, so that the filter permeation tank 2 and the chip collection cylinder 33 can be directly removed from the filter box by hand for waste cleaning.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
