Abstract
Description
Technical Field
[0001] This application relates to the field of solid-liquid separation equipment technology in the pharmaceutical industry, and in particular to a filter press that facilitates waste residue cleaning. Background Technology
[0002] Solid-liquid separation equipment in the pharmaceutical industry is mainly used in drug production to separate solid drug particles from liquid solvents, ensuring drug quality and production efficiency. Some waste residues contain corrosive substances, sticky substances, or mixtures with large particle size variations. For example, waste residues generated in the pharmaceutical industry may be both corrosive and sticky. Traditional filter presses are prone to problems such as filter plate corrosion and difficult-to-clean waste residues during unloading and cleaning. Filter presses that facilitate waste residue cleaning feature adaptive elastic unloading plates that can handle waste residues with different characteristics, and a self-cleaning linkage mechanism for the filter cloth that can promptly remove residual waste residues, preventing corrosion and clogging, and meeting the processing requirements of complex waste residues.
[0003] By utilizing pressure difference, a suspension is forced through a filter cloth, allowing the liquid to pass through and be discharged, while solid particles are retained, thus achieving solid-liquid separation. Whether it's chemical waste, metallurgical waste, or other industrial waste, a filter press can separate the liquid, reducing the water content and facilitating subsequent processing and transportation. For example, in mining, the slurry formed after ore crushing contains a large amount of water; a filter press can quickly separate the water from the slurry, obtaining slag with lower water content.
[0004] In existing technologies, some filter presses are difficult to clean waste residue, resulting in serious waste residue residue on filter plates and filter cloths, clogging the pores of the filter cloths and affecting the liquid permeability in the subsequent solid-liquid separation process. The residual waste residue contains corrosive substances, which, if they adhere to the surface of filter plates, filter cloths and other equipment components for a long time, will accelerate the corrosion and wear of these components. Therefore, a filter press that is easy to clean waste residue is proposed to solve the above problems. Utility Model Content

[0015] Through the above technical solution: multiple filter plates slide within the support frame, and the hydraulic cylinder pushes the filter plates to fit tightly together to form a filtration chamber, so that the slurry can achieve solid-liquid separation under pressure. In addition, the hydraulic cylinder can control the opening and closing of the filter plates, which facilitates the switching of filtration and cleaning processes.

[0023] Through the above technical solution: the spring provides elastic support and buffer protection for the perforated plate; the pipe slides on the inner wall of the collection box without affecting its operation; the moving plate slides outside the box to cooperate with the lifting and lowering of the perforated plate, making the collection component more stable and efficient in the process of solid-liquid separation and waste conveying.

The scraper at the bottom scrapes off the filter cake on the surface of the filter plate. At the same time, the water pump draws water from the water tank through pipe two and delivers it through pipe one to the nozzle at the bottom of the support block to perform high-pressure washing of the filter plate. The scraped waste residue and washing water fall together into the collection box of the collection component below, realizing the cleaning of waste residue of the filter press, thereby reducing the downtime caused by cleaning waste residue, increasing the equipment running time, and improving production efficiency;
[0026] 2. In this utility model, the perforated plate in the collection box, supported by a sliding rod and a spring, can elastically rise and fall according to the weight of the waste residue. The filtrate is discharged through the perforated plate, and the solid waste residue is temporarily stored on the perforated plate. The motor drives the rotating column and the auger to transport the waste residue from right to left, and finally discharge it through the outlet. This achieves anti-clogging of the filter press, thereby avoiding the impact of waste residue accumulation on the unloading of the filter press, reducing the complex maintenance work caused by clogging problems, and saving maintenance time and labor costs.

[0032] The following is in conjunction with the appendix Figure 1 - Appendix Figure 4 This application will be described in further detail below.
[0033] Example: A filter press that facilitates waste residue cleaning, referring to... Figures 1 to 3 The frame assembly includes a frame assembly 1, a filter plate assembly 2 is installed inside the frame assembly 1, a drive assembly 3 is installed on the top of the frame assembly 1, a cleaning assembly 4 is installed inside the drive assembly 3, a collection assembly 5 is installed inside the frame assembly 1, and a discharge port 6 is installed on the left side of the collection assembly 5.
[0034] The drive assembly 3 includes a square bracket 31, the interior of which is installed on the exterior of the frame assembly 1. A motor 32 is fixedly connected to the front of the square bracket 31. A rotating rod 33 is fixedly connected to the drive end of the motor 32. The rod rotates under the drive of the motor 32, and the sprocket 34 fixed on its exterior rotates accordingly. Power is transmitted to the rotating rod 35 via a chain 37, realizing the transmission and conversion of power. The rotating rod 33 is fixedly connected to the exterior of the sprocket 34, which rotates under the drive of the rotating rod 33. The rotation of the rotating rod 33 is achieved through the cooperation of the chain 37 and the sprocket 36. The power is transmitted to the rotating rod 35 to ensure the stability and accuracy of power transmission. The rotating rod 35 is fixedly and rotatably connected inside the square bracket 31. The sprocket 36 is fixedly connected to the outside of the rotating rod 35. The chain 37 is sleeved on the outside of the sprocket 36. The chain 37 transmits the power of the rotating rod 33 to the rotating rod 35, so that the cleaning component 4 can perform horizontal reciprocating motion in the square opening of the square bracket 31 to scrape the filter cake on the surface of the filter plate 21. The inside of the chain 37 is sleeved on the outside of the sprocket 34. The rear side of the rotating rod 33 is rotatably connected to the rear inner wall of the square bracket 31.
[0035] Specifically, motor 32 converts electrical energy into mechanical energy, driving rotating rod 33 to rotate. The sprocket 34 on rotating rod 33 rotates accordingly. With the help of chain 37 and sprocket 36, the power is stably and accurately transmitted to rotating rod 35. After receiving power, rotating rod 35 rotates, driving the square block 41 of cleaning component 4 through chain 37, causing it to reciprocate horizontally within the square opening of square bracket 31. This allows the scraper 42 at the bottom of square block 41 to slide along the surface of filter plate 21, scraping off the filter cake. At the same time, it works with nozzle 45 to rinse filter plate 21, achieving efficient cleaning of waste residue on the surface of filter plate 21.
[0036] The cleaning component 4 includes a square block 41. The square block 41, connected to a chain 37, reciprocates horizontally under the drive of the drive component 3, cleaning the filter cake on the surface of the filter plate 21. Scrapers 42 are fixedly connected to the bottom left and right sides of the square block 41. The scrapers 42 scrape off the filter cake adhering to the surface of the filter plate 21, separating it for subsequent collection and processing. A support block 44 is fixedly connected inside the square bracket 31. A pipe 46 connected inside the support block 44 distributes water from the water pump 47 to various nozzles 45, allowing the nozzles 45 to evenly rinse the surface of the filter plate 21, improving the cleaning effect. Multiple nozzles 45 are fixedly connected to the bottom of the support block 44. A pipe 46 is fixedly connected inside the support block 44, with the other end of the pipe 46 fixedly connected to the water pump 47. The nozzles 45 distribute the water pumped by the water pump 47... Water is sprayed out in the form of high pressure to rinse the surface of filter plate 21, removing residual waste and impurities. In conjunction with scraper 42, the filter plate 21 is thoroughly cleaned. The input end of water pump 47 is fixedly connected to pipe 48, and the right side of pipe 48 is fixedly connected to water tank 49. Water tank 49 is used to store the water required for rinsing filter plate 21 and to provide water source for water pump 47. Limiting blocks 43 are fixedly connected to the front and rear sides of square block 41. Square openings are opened inside the front and rear sides of square bracket 31. The outside of the limiting block 43 is slidably connected to the inside of the square opening. The limiting block 43 cooperates with the square openings opened inside the front and rear sides of square bracket 31 to restrict the movement trajectory of square block 41, ensuring that square block 41 can slide stably in the horizontal direction and preventing deviation during movement. This ensures that scraper 42 can accurately clean the surface of filter plate 21.
[0037] Specifically, water tank 49 stores water and transports it to water pump 47 via pipe 2 48. After being pressurized, water pump 47 distributes the water to nozzles 45 at the bottom of support block 44 via pipe 1 46. Nozzles 45 spray water at high pressure to rinse the surface of filter plate 21, removing residual waste and impurities, and achieving deep cleaning in conjunction with scraper 42. The cooperation between limit block 43 and the square opening of square bracket 31 restricts the movement trajectory of square block 41, ensuring that scraper 42 and nozzles 45 can accurately act on the surface of filter plate 21, improving the cleaning effect and stability.
[0038] The frame assembly 1 includes a base 11, with a support frame 12 mounted on top of the base 11. Multiple bolts 13 are threaded into the interior of the base 11. The support frame 12 is welded from two parallel beams and multiple columns, forming a sliding pair with the sliders on both sides of the filter plate 21. This ensures smooth movement and precise positioning of the filter plate 21. The support frame 12 guarantees smooth sliding of the filter plate 21 within it, enabling the opening and closing of the filter plate 21, thereby completing the formation and separation of the filtration chamber. It is a crucial support structure for the filter press to achieve its filtration function. The bolts 13, through threaded connection with the base 11, fix the filter press in a designated position. The installation position and stability can be adjusted according to actual installation requirements, ensuring that the equipment does not shake due to vibration or other factors during operation. The filter plate assembly 2 includes... Multiple filter plates 21 are externally slidably connected to the inside of the support frame 12. Under the action of the hydraulic cylinder 22, they are tightly fitted to form a filter chamber. After the slurry enters the filter chamber, the filtrate passes through the filter cloth and is discharged. The waste residue adheres to the surface of the filter plate 21 to form a filter cake, thus realizing the function of solid-liquid separation. The hydraulic cylinder 22 is installed on the right side of the filter plate 21. The hydraulic cylinder 22 pushes the filter plate 21 to open and close through the extension and retraction action, controlling the formation and separation of the filter chamber. During the filtration process, sufficient pressure is provided to keep the filter plate 21 tightly fitted to ensure the filtration effect. After filtration, the filter plate 21 is retracted to separate, which facilitates the subsequent waste residue cleaning work. The bottom of the water pump 47 is fixedly connected to the top left side of the base 11, and the bottom of the water tank 49 is fixedly connected to the top rear side of the base 11.
[0039] Specifically, the base 11 serves as the foundation and is firmly fixed to the ground installation position by bolts 13. The stability can be flexibly adjusted to withstand the pressure and vibration during equipment operation, ensuring overall stability. The support frame 12 has a robust welded structure, and the sliding pair formed between it and the slider of the filter plate 21 ensures that the filter plate 21 moves accurately and smoothly. In the filter plate assembly 2, multiple filter plates 21 slide within the support frame 12. When the hydraulic cylinder 22 extends, it pushes the filter plates 21 to fit tightly together to form a closed filtration chamber. After the slurry enters, the filtrate is discharged through the filter cloth under pressure, and the waste residue adheres to the surface of the filter plate 21 to form a filter cake, completing the core operation of solid-liquid separation. After filtration, the hydraulic cylinder 22 retracts, causing the filter plates 21 to separate, and promptly switches to the waste residue cleaning mode, creating conditions for the cleaning component 4 to smoothly clean the filter cake on the surface of the filter plate 21, so that all parts of the filter press are connected in an orderly manner and operate continuously and efficiently.
[0040] Reference Figure 1 and Figure 4The collection component 5 includes a collection box 51, the bottom of which is mounted on the top of the base 11. A second motor 52 is mounted on the right side of the collection box 51. The second motor 52 drives a rotating column 53 to rotate via its drive end, converting electrical energy into mechanical energy to power the auger 54 for conveying waste residue, allowing the waste residue to be discharged from the collection box 51. The rotating column 53 is fixedly connected to the drive end of the second motor 52. The rotating column 53 rotates under the drive of the second motor 52, and the auger 54 fixed outside it rotates accordingly, conveying the waste residue from the right side to the left of the collection box 51, realizing the directional movement of the waste residue. The auger 54 is fixedly connected to the outside of the rotating column 53. Multiple sliding rods 55 are slidably connected inside the collection box 51, and the tops of the multiple sliding rods 55 are fixedly connected to perforated parts. The bottom of the plate 56 and multiple sliding rods 55 are fixedly connected to a movable plate 57. When the weight of the waste residue changes, the porous plate 56 and the movable plate 57 can slide up and down, so that the porous plate 56 can rise and fall elastically with the weight of the waste residue, ensuring that the filtrate can be discharged smoothly. The bottom of the movable plate 57 is fixedly connected to multiple springs 58. The springs 58 provide elastic support for the movable plate 57 and the porous plate 56, so that the porous plate 56 can rise and fall elastically when the weight of the waste residue changes, ensuring that the filtrate can be discharged smoothly, and at the same time, it plays a buffering and protective role for the porous plate 56. The bottom of the multiple springs 58 is fixedly connected to the top of the base 11. The left and right sides of the pipe 46 are slidably connected to the inner wall of the collection box 51, and the adjacent sides of the two movable plates 57 are slidably connected to the outside of the collection box 51.
[0041] Specifically, in the collection component 5, the collection box 51 is used to receive waste residue and rinsing water. The motor 52 drives the rotating column 53 and the auger 54 to transport the waste residue from right to left and discharge it through the discharge port 6. The sliding rod 55, the perforated plate 56, the moving plate 57 and the spring 58 work together to make the perforated plate 56 elastically rise and fall with the weight of the waste residue, so that the filtrate is discharged through the perforated plate 56 and the solid is temporarily stored. This not only completes the secondary separation of solid and liquid, but also buffers and protects the perforated plate 56, ensuring efficient collection, separation and discharge of waste residue.
[0042] Working principle: The filter plates 21 are tightly fitted together under the push of the hydraulic cylinder 22 to form a filter chamber. The slurry is injected through the feed port. Under pressure, the filtrate passes through the filter cloth and is discharged. The waste residue adheres to the surface of the filter plate to form a filter cake. After filtration is completed, the hydraulic cylinder 22 retracts to separate the filter plates 21.
[0043] When motor 32 is started, it drives rotating rod 33 to rotate, which in turn drives sprocket 34 to rotate. Sprocket 34 drives chain 37 to move, and through chain 37, it drives sprocket 36 to drive the square block 41 of cleaning component 4 connected to chain 37 to move horizontally back and forth along the square opening of square bracket 31. The scraper 42 at its bottom scrapes off the filter cake on the surface of filter plate 21. At the same time, water pump 47 draws water from water tank 49 through pipe 48 and delivers it through pipe 46 to nozzle 45 at the bottom of support block 44 to perform high-pressure rinsing of filter plate 21. The scraped waste and rinsing water fall into collection box 51 of collection component 5 below.
[0044] The perforated plate 56 in the collection box 51 can be elastically raised and lowered according to the weight of the waste residue under the support of the sliding rod 55 and the spring 58. The filtrate is discharged through the perforated plate 56, and the solid waste residue is temporarily stored on the perforated plate 56. The motor 2 52 drives the rotating column 53 and the auger 54 to transport the waste residue from right to left, and finally discharge it through the discharge port 6.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
