Description

Technical Field

[0001] This utility model relates to the field of leachate processing technology, specifically to a rapid filtration device for leachate with automatic slag discharge function. Background Technology

[0002] In the production processes of chemical, food, and pharmaceutical industries, leaching is the core step in extracting the effective components from raw materials. By fully contacting the solid raw materials with a solvent, the target effective components are dissolved to form an extract, which is then processed into the final product through subsequent concentration, purification, crystallization, and other processes.

[0003] Among them, the filtration and purification of the leachate is a key intermediate step. In the existing production process, when the leachate is discharged through the pipeline, it is inevitable that residues will be introduced, affecting subsequent processing. If the solid residues remaining in the leachate (such as raw material debris, undissolved particles, flocculent impurities, etc.) are not effectively removed, it will not only cause blockage of subsequent processing equipment (such as evaporator heating tubes and centrifuge filters, increasing the frequency of equipment cleaning and downtime, but may also affect the purity of the product (such as excessive impurities in the pharmaceutical field and deterioration of taste in the food field), and even cause product quality risks. Utility Model Content

[0004] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0005] In view of the above-mentioned problems and existing problems in the processing of leachate, this utility model is proposed.

[0006] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution: A rapid filtration device for leachate with automatic slag discharge function includes a leachate tank and a first discharge pipe. A discharge pipe is provided on the side of the leachate tank. The top end of the first discharge pipe is installed on the surface of the leachate tank through a flange. A spiral tube is provided inside the first discharge pipe. A connector is fixedly installed at the top end of the spiral tube and is fixedly connected to the discharge pipe. A discharge head is fixedly installed at the bottom end of the spiral tube, and the surface of the discharge head penetrates the first discharge pipe.

[0007] As a preferred embodiment of the leachate rapid filtration device with automatic slag discharge function described in this utility model, the first discharge pipe is divided into a central part and two connecting ends. The two connecting ends are respectively fixedly connected to the two ends of the central part. The connecting end at the top of the first discharge pipe is installed on the surface of the leachate tank through a flange. The connecting end at the bottom of the first discharge pipe is fixedly connected to a second discharge pipe.

[0008] As a preferred embodiment of the leachate rapid filtration device with automatic slag discharge function described in this utility model, the first discharge pipe is generally inclined, and the second discharge pipe is horizontally arranged.

[0009] As a preferred embodiment of the leachate rapid filtration device with automatic slag discharge function described in this utility model, the central part is made of transparent material.

[0010] As a preferred embodiment of the leachate rapid filtration device with automatic slag discharge function described in this utility model, the surface of the spiral tube is provided with filter pores, the interior of the discharge head is provided with a hollow cavity, and the inner wall of the hollow cavity is provided with a smooth surface.

[0011] As a preferred embodiment of the leachate rapid filtration device with automatic slag discharge function described in this utility model, a sealing column is installed inside the hollow cavity, a threaded groove is opened at the bottom end of the inner wall of the hollow cavity, and a threaded surface corresponding to the threaded groove is provided at the bottom of the sealing column.

[0012] As a preferred embodiment of the leachate rapid filtration device with automatic slag discharge function described in this utility model, a rubber head is provided at the top of the sealing column.

[0013] Compared with the prior art, the beneficial effects of this utility model are: The spiral structure of the spiral tube significantly increases the filtration area within a limited space, prolonging the contact time between the leachate and the filter pores. Combined with the filter pores with customizable pore sizes, it can efficiently trap fine residues, greatly reducing the risk of residue leakage. At the same time, the spiral path disperses the liquid impact force, reducing local blockage and extending the service life of the spiral tube. The first discharge pipe is set at an angle, which uses gravity to help the filtered liquid flow to the bottom, reducing the residence time in the center and avoiding a decrease in filtration efficiency due to liquid accumulation, thus ensuring continuous filtration. The spiral tube guides the residue to slide directionally towards the bottom, and together with the discharge head that runs through the first discharge pipe, it forms a completely independent slag discharge path, thus completely avoiding cross-contamination during slag discharge.

[0016] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0017] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, in actual manufacturing, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings. Example 1

[0019] Please see Figures 1-4 This utility model provides a technical solution: A rapid filtration device for leachate with automatic slag discharge function includes a leachate tank 1 and a first discharge pipe 2. A discharge pipe is provided on the side of the leachate tank 1. The top end of the first discharge pipe 2 is installed on the surface of the leachate tank 1 via a flange. A spiral tube 6 is provided inside the first discharge pipe 2. A connector 7 is fixedly installed at the top end of the spiral tube 6 and is fixedly connected to the discharge pipe. A discharge head 8 is fixedly installed at the bottom end of the spiral tube 6, and the surface of the discharge head 8 penetrates the first discharge pipe 2. In this device, the spiral structure of the spiral tube 6 significantly increases the filtration area within a limited space, prolongs the contact time between the leachate and the filter pores, and, in conjunction with the filter pores with customizable pore size, can efficiently trap fine residues. At the same time, the spiral tube 6 can guide the residues to slide directionally towards the bottom end, forming a completely independent slag discharge path in conjunction with the discharge head penetrating the first discharge pipe 2, thus completely avoiding cross-contamination during slag discharge.

[0020] The first discharge pipe 2 is divided into a central part 4 and two connecting ends 5. The two connecting ends 5 are fixedly connected to the two ends of the central part 4 respectively. The connecting end 5 at the top of the first discharge pipe 2 is installed on the surface of the leaching tank 1 through a flange. The connecting end 5 at the bottom of the first discharge pipe 2 is fixedly connected to the second discharge pipe 3. The spiral structure of the spiral tube 6 increases the filtration area in a limited space, prolongs the contact time between the leachate and the filter pores, and improves the filtration accuracy. At the same time, the spiral path guides the residue to slide directionally to the bottom. Together with the discharge head 8 that runs through the first discharge pipe 2, it forms an independent discharge channel, avoiding the mixing of residue and clear liquid and reducing secondary pollution. The spiral tube 6 is built into the first discharge pipe 2, eliminating the need for external filtration equipment and saving space. The discharge head 8 runs directly through the pipe, so there is no need to disassemble the pipe to discharge slag, simplifying operation and adapting to continuous production needs.

[0021] The first discharge pipe 2 is set at an angle, while the second discharge pipe 3 is set horizontally. The slope of the first discharge pipe 2 uses gravity to assist the clear liquid to flow to the bottom, reducing the residence time of the clear liquid in the center 4. Compared with the horizontally set pipe, it avoids the decrease in filtration efficiency due to liquid accumulation. The horizontal setting of the second discharge pipe 3 can be precisely connected to the horizontal feed inlet of subsequent processing equipment (such as storage tanks and concentrators), reducing the risk of fluid impact and leakage caused by pipe angle deviation, and ensuring the continuity of the production line.

[0022] The surface of the spiral tube 6 is provided with filter pores, and the interior of the discharge head 8 is provided with a hollow cavity 9. The inner wall of the hollow cavity 9 is made into a smooth surface. The pore size of the filter pores can be customized according to the particle size of the residue, which can efficiently intercept fine residues. The pores are distributed on the surface of the spiral tube 6, which disperses the liquid impact force, reduces local blockage, and extends the service life of the spiral tube 6.

[0023] The central section 4 is made of transparent material, allowing operators to directly observe the height of residue accumulation inside the spiral tube 6 in the central section 4. This facilitates subsequent operations, makes the timing of slag discharge more precise, and avoids inefficiency caused by premature slag discharge or blockage caused by late slag discharge.

[0024] During use, the leachate (containing solid residue) in the leachating tank 1 flows out through the drain pipe on the side and enters the interior of the spiral tube 6 through the connector 7 at the top of the spiral tube 6. As the leachate flows along the spiral path of the spiral tube 6, the clear liquid permeates through the filter pores on the surface of the spiral tube 6 to the center 4 of the first discharge pipe 2, while the residue is intercepted by the filter pores and slides to the bottom of the spiral tube 6 under the action of gravity and spiral guidance. The first discharge pipe 2 is set at an overall inclination, and the clear liquid in the center 4 flows to the bottom under the action of gravity and inclination slope, and enters the horizontally set second discharge pipe 3 through the bottom connector 5. Finally, it is smoothly transported to the subsequent processing steps by the second discharge pipe 3. The intercepted residue continues to slide down the inner wall of the spiral tube 6 and enters the bottom discharge head 8, and is finally discharged through the discharge head 8 that penetrates the first discharge pipe 2. Example 2

[0025] Please see Figures 1-4 This utility model provides a technical solution: A sealing column 10 is installed inside the hollow cavity 9. A threaded groove 12 is opened at the bottom end of the inner wall of the hollow cavity 9. A threaded surface 13 corresponding to the threaded groove 12 is provided at the bottom of the sealing column 10. The sealing column 10 and the hollow cavity 9 are connected by the threaded surface 13 and the threaded groove 12. The sealing degree can be precisely controlled by rotating the angle. The operation is simple and intuitive, without the need for complex pneumatic or electric control components. It is suitable for manual operation in small and medium-sized production scenarios, reducing equipment costs.

[0026] A rubber head 11 is provided at the top of the sealing column 10. The rubber head 11 at the top of the sealing column 10 has elastic deformation capability. When tightened, it can fit tightly against the outlet at the bottom of the spiral tube 6, filling the gap and forming a flexible seal.

[0027] Unlike Embodiment 1, when the device is in the filtration state, the sealing column 10 is tightened with the threaded groove 12 at the bottom of the inner wall of the hollow cavity 9 through the threaded surface 13 at the bottom, so that the rubber head 11 at the top of the sealing column 10 is tightly attached to the outlet at the bottom of the spiral tube 6. At this time, the rubber head 11 fills the gap through elastic deformation, forming a reliable seal to prevent the leachate (liquid that is not completely filtered) or residue in the spiral tube 6 from leaking from the discharge head 8 during the filtration process, ensuring that all leachate is filtered through the filter pores on the surface of the spiral tube 6. When the operator observes through the transparent center part 4 that the residue in the spiral tube 6 has accumulated to the height required for slag discharge, the sealing column 10 is rotated so that the threaded surface 13 at the bottom of the spiral tube 6 is screwed out of the threaded groove 12, and the sealing column 10 moves downward as a whole. The rubber head 11 at the top of the spiral tube 6 is disengaged from the outlet at the bottom of the spiral tube 6. At this time, the residue in the spiral tube 6 slides down the inner wall of the spiral tube 6 to the hollow cavity 9 under the action of gravity and the slight thrust of the subsequent leachate, and is then discharged from the discharge head 8 through the open channel.

[0028] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
