Description

TECHNICAL FIELD

[0001] The utility model relates to filter machine technical field especially relates to a disc type vacuum filter. BACKGROUND

[0002] Electrolytic manganese residue, as an inevitable byproduct in the production process of electrolytic manganese, usually contains a large amount of impurities and has a relatively high moisture content. Due to its unique chemical composition and physical properties, the treatment of electrolytic manganese residue has become a thorny problem in the field of industrial production. In the traditional treatment method, filtration technology is widely used, however, in practical application, many existing filter equipment encounters many technical problems in the treatment of electrolytic manganese residue. These difficulties mainly focus on the improvement of filtration efficiency, the optimization of cleaning frequency, the smoothness of liquid discharge process and the convenience of discharge operation, etc. There are certain limitations in these aspects, which limit the application effect of filtration technology in the treatment of electrolytic manganese residue. In the process of manganese residue treatment, the traditional filter equipment such as plate and frame filter press and diaphragm filter press mainly relies on pressure filtration to realize solid-liquid separation. The plate and frame filter press squeezes the filter cake through fixed filter plate, and the diaphragm filter press further compresses the filter cake through diaphragm expansion, which is suitable for relatively clean solid-liquid separation. However, electrolytic manganese residue contains more chemical residues and fine impurities, and single washing often fails to achieve the effect of deep cleaning.

[0003] In the patent "Filtering structure of low-grade manganese ore refining electrolytic manganese separation and extraction equipment" (publication number CN217869117U, hereinafter referred to as prior art 1), a filtering structure for manganese residue extraction is disclosed; in prior art 1, the stepping motor drives the transmission wheel to rotate in reverse, and the transmission belt moves the brush on the surface of the filter screen, removing the manganese residue on the surface, so as to achieve the purpose of cleaning the manganese residue, avoiding the blockage of the filter screen, improving the filtering efficiency and the functionality of the device. By pulling the sliding block, it moves in the sliding groove, drives the filter screen to separate from the shell, prevents solution leakage by using sealing gasket, and reduces the friction between the sliding block and the sliding groove by using the roller, realizes the convenient replacement of the device, facilitates the disassembly and maintenance of the filter screen, and improves the ease of use of the device. In addition, the push plate controls the falling speed by blocking the solution flow, the servo motor drives the push plate to rotate, adjusts the falling rate of the solution, realizes the feeding control function of the device, and ensures that the device will not be affected by too much one-time feeding.

[0004] Although the existing technology 1 can achieve the cleaning and filtration of filter residue, it uses a combination of filter screen and brush to complete the solid-liquid separation and manganese slag filtration. However, this single filter screen configuration has certain limitations; it cannot effectively handle manganese slag solutions with high impurities and high water content. When attempting to filter such solutions, filter screen clogging may occur, affecting filtration efficiency and effectiveness. Utility Model Content

[0005] In view of this, the present invention provides a disc-type vacuum filter to solve the problem that traditional filter presses are not adaptable to manganese slag with high impurities and high water content, making it difficult to process slurries with complex components, thus affecting separation quality and efficiency.

[0016] The disc-type vacuum filter provided by this utility model has the following beneficial effects:

[0017] In this invention, electrolytic manganese slag typically contains a large amount of impurities and moisture. Traditional filtration equipment may struggle to efficiently process such materials. This filter employs a rotary design, making the filtration process more uniform and continuous, effectively handling electrolytic manganese slag with high moisture content and numerous impurities. Multiple filter discs are evenly spaced, each with an independent liquid guide pipe connected to the drainage mechanism, enabling highly efficient filtration. This design improves the working efficiency of each filter disc, reducing the burden on individual discs and enhancing overall filtration efficiency. Traditional filtration equipment may require frequent manual intervention, such as feeding, cleaning, and discharging. This rotating operation allows the filter components to automatically complete these tasks sequentially through the feeding, cleaning, filtering, and drainage mechanisms, significantly improving automation and continuity while reducing manual operation. During filtration, the filter discs are prone to contamination or clogging, especially when processing electrolytic manganese slag with high impurity content. Attached Figure Description

[0033] Example 1

[0034] Please see Figure 1 This utility model provides a disc-type vacuum filter for treating electrolytic manganese slag generated during the electrolytic manganese production process. Traditional plate and frame filter presses and diaphragm filter presses face the following problems when treating manganese slag: poor washing effect, high energy consumption, and poor adaptability. Plate and frame filter presses cannot perform multiple washing operations, only removing some impurities through a single filtration. Diaphragm filter presses consume a lot of energy during multiple expansion processes, increasing processing costs, and the washing process is difficult to completely remove impurities, affecting the separation effect. Plate and frame filter presses and diaphragm filter presses mainly rely on mechanical pressure, making deep cleaning difficult during the washing process, resulting in incomplete impurity removal. Diaphragm filter presses require continuous pressurization and expansion using a high-pressure pump for washing operations, leading to high energy consumption. When processing materials with high moisture content, the filter cloth of plate and frame filter presses is prone to clogging, increasing cleaning difficulty. Furthermore, traditional filter presses are not adaptable to manganese slag with high impurity and moisture content, making it difficult to handle slurries with complex compositions, affecting separation accuracy and effect.

[0035] In this embodiment, a disc-type vacuum filter is provided, which can ensure the processing efficiency and quality when processing manganese slag containing many impurities and high moisture content.

[0036] Please see Figure 1 and Figure 2 In this embodiment, the disc-type vacuum filter includes a rotating base 200 disposed on the inner ring of the operating platform 100; the operating platform 100 is fixedly disposed on the periphery of the rotating base 200, forming a structure surrounding the rotating base 200, thereby completely enclosing the rotating base 200; the operating platform 100 not only provides a stable structural foundation, but can also be used to fix other components, and facilitate the inspection and maintenance of these components.

[0037] Furthermore, the operating platform 100 can be a wall constructed by civil engineering or a platform built by mechanical steel frame. The specific form can be determined according to actual needs and site conditions.

[0038] In addition, please see Figure 2 The rotating base 200 is located in the middle part of the operating platform 100 and can rotate freely. This design allows the rotating base 200 to drive the filter assembly 300 to perform a rotating filtration operation, thereby improving filtration efficiency and the continuity of operation.

[0039] Please see Figure 2 In this embodiment, the disc-type vacuum filter further includes a filter assembly 300 and a draining mechanism 400 disposed on the rotating base 200. Both components and mechanisms rotate based on the rotating base 200. The filter assembly 300 is configured to perform rotary filtration, effectively capturing and separating solid particles suspended in the liquid during the filtration process. After completing the filtration task, the filter assembly 300 discharges the filtrate generated during the filtration process through the cooperating draining mechanism 400. The function of the draining mechanism 400 is to discharge the liquid accumulated in the filter assembly 300, ensuring the continuity and efficiency of the filtration process. The entire filtration and draining process is automated, greatly reducing the need for manual intervention and improving the efficiency and reliability of the filtration operation.

[0040] Please see Figure 2In this embodiment, the filter assembly 300 includes multiple filter discs 310 arranged at uniform angular intervals. Each filter disc 310 is connected to the drainage mechanism 400 via an independently provided liquid guide pipe 410. The main function of these filter discs 310 is to hold the manganese slag to be filtered. After the manganese slag in the filter disc 310 has completed the filtration process, the filter disc 310 will retain the filtrate used for filtering the manganese slag and the unfiltered manganese slag residue. To ensure the smooth progress of the filtration process, each filter disc 310 is provided with funnel-shaped filter holes 311 connected to the liquid guide pipe 410. In addition, the filter disc 310 is also equipped with a filter screen to intercept the manganese slag and prevent it from entering the liquid guide pipe 410. After the filtration process is completed, the manganese slag will remain on the filter screen, i.e., inside the filter disc 310. At the same time, the filtrate used for filtering the manganese slag will be discharged through the filter holes by the filtration effect of the filter screen. The filtrate is then discharged through a guide pipe, thus achieving solid-liquid separation of the filtrate and manganese slag. By providing an independent guide pipe 410 for each filter plate 310, the filtrate from different areas can be recovered separately, ensuring the high efficiency of the filtration process and the purity of the filtrate.

[0041] Please see Figure 2 and Figure 3 Above the filter assembly 300, a feeding mechanism 500, a cleaning mechanism, and a discharging mechanism 700 are also provided. These mechanisms are spaced apart in the upper region of the filter assembly 300 to facilitate their respective functions. The main function of the feeding mechanism 500 is to evenly add materials, such as electrolytic manganese slag, into the filter disc 310 for subsequent filtration. Meanwhile, the cleaning mechanism is responsible for effectively cleaning the materials in the filter disc 310 when it rotates to a specific position. The discharging mechanism 700 discharges the filtered manganese slag, preventing it from remaining in the filter disc 310 for an extended period. This not only avoids the accumulation of manganese slag affecting the filtration efficiency of the filter disc 310 but also prevents the accumulation of cleaning liquid and filter slag mixture within the filter disc 310 due to excessive slag buildup, which could potentially cause cleaning liquid overflow. These mechanisms—feeding mechanism 500, cleaning mechanism and discharge mechanism 700—are all located on the top of filter disc 310, and the top of filter disc 310 is designed to be open. This design ensures that materials and cleaning fluid can enter the interior of filter disc 310 unimpeded, thereby facilitating the filtration operation.

[0042] Please see Figure 1 , Figure 3 and Figure 4In this embodiment, the drainage mechanism 400 includes a distribution head 420 connected to the liquid guide pipe 410. The distribution head 420 has multiple connection ports for effective connection to each filter disc 310 or the filtration component. The distribution head 420 is further connected to a vacuum pump to achieve vacuum filtration. After thoroughly cleaning the manganese slag in the filter disc 310, the cleaning liquid needs to be filtered and discharged. However, a large amount of manganese slag in the filter disc 310 may clog the filter screen, hindering the discharge of the cleaning liquid. To solve this problem, a vacuum pump is added for vacuuming. Through the liquid guide pipe 410, the cleaning liquid in the filter disc 310 can be effectively extracted by the vacuum pump, ensuring the smooth progress of cleaning and filtration operations.

[0043] During the filtration process, each component remains in its fixed position to perform its respective task within its designated area. Therefore, to ensure smooth filtration, the filter assembly 300, driven by the rotary table 200, must sequentially pass through the positions of the feeding mechanism 500, the washing mechanism, and the discharging mechanism 700, completing the operational steps assigned to each mechanism in turn. This series of operations aims to effectively treat electrolytic manganese slag with high moisture content and numerous impurities, thereby ensuring that the final filtration effect meets the expected standards.

[0044] Further, please see Figure 2 Because residual manganese slag remains after the cleaning liquid is discharged through vacuum filtration, it adheres to the filter screen due to the suction generated during vacuum filtration and cannot be discharged through the discharge mechanism 700. If left untreated, the filter screen will become clogged or even damaged over time. Therefore, in this embodiment, a blowing and washing mechanism 800 for cleaning the filter screen of the filter assembly 300 is also provided. The blowing and washing mechanism 800 is located at the bottom of the filter disc 310 and positioned between the discharge mechanism 700 and the feeding mechanism 500. After the filter disc 310 has completed the cleaning of manganese slag and the discharge of the cleaning liquid by the cleaning mechanism, most of the manganese slag is discharged through the discharge mechanism 700, while a small amount of manganese slag remains attached to the filter screen. Therefore, after the cleaning liquid and most of the manganese slag have been discharged, the filter screen is cleaned by blowing and washing mechanism 800, causing the manganese slag attached to the filter screen to detach from the filter screen and re-mix into the cleaning liquid, so that it can be discharged in the next cycle. To ensure the cleanliness of the filter screen and extend its service life, the 800-stage purging mechanism is particularly important. It uses high-pressure gas or liquid to flush the filter screen, effectively removing residues and ensuring a smooth filtration process. This also prevents decreased production efficiency and equipment damage caused by filter clogging. Air compression equipment can be used for purging.

[0045] Please see Figure 4 The distribution head 420 is divided into at least a first cleaning section 421, a second cleaning section 422, a third cleaning section 423, and a rinsing section 424 through the filtration operation. The connection ports of the first cleaning section 421, the second cleaning section 422, the third cleaning section 423, and the rinsing section 424 are respectively designated as a first washing liquid outlet 425, a second washing liquid outlet 426, a third washing liquid outlet 427, and a rinsing port 428. The filtrate after washing in each section is collected through the distribution head 420 and then discharged through the first washing liquid outlet 425, the second washing liquid outlet 426, and the third washing liquid outlet 427, respectively, for easy treatment and reuse, and to reduce water consumption.

[0046] Please see Figure 2 The cleaning mechanism includes a first cleaning mechanism 610, a second cleaning mechanism 620, and a third cleaning mechanism 630; the first cleaning mechanism 610, the second cleaning mechanism 620, and the third cleaning mechanism 630 are arranged at intervals above the filter assembly 300; the first cleaning mechanism 610, the second cleaning mechanism 620, and the third cleaning mechanism 630 are respectively provided with a first washing liquid inlet 611, a second washing liquid inlet 621, and a third washing liquid inlet 631.

[0047] The material (electrolytic manganese slag) is added to the filter plate 310 through the feeding mechanism 500, and the feeding mechanism 500 feeds the material through the feed port 510.

[0048] The cleaning solutions from the first cleaning mechanism 610, the second cleaning mechanism 621, and the third cleaning mechanism 630 enter the filter plate 310 from the first cleaning solution inlet 611, the second cleaning solution inlet 621, and the third cleaning solution inlet 631, respectively.

[0049] The first stage of cleaning involves the first cleaning unit 610 performing preliminary cleaning of the manganese slag. This stage removes larger particles, scum, and debris from the surface of the manganese slag. These impurities may include coarse particles and silt that were not completely filtered out from the electrolytic manganese slag, which are usually easily removed by physical methods. Generally, the manganese slag in the filter plate 310 is initially rinsed with clean water to remove most of the surface-attached impurities. The rinsing with clean water effectively removes relatively loose impurities and prepares the filter for subsequent cleaning stages.

[0050] The second stage of cleaning is carried out by the second cleaning unit 620. After the initial cleaning, some chemicals may still remain on the surface of the manganese slag, such as chemical additives used in the filtration process, dissolved metal ions, or some salts. The goal of the secondary cleaning is to further remove these residual chemicals. Acidic cleaning solutions (such as diluted sulfuric acid or hydrochloric acid) are generally used. Acidic cleaning solutions can dissolve and remove some organic or inorganic residues, helping to remove any chemicals that are insoluble in acids or alkalis.

[0051] The third stage involves cleaning the manganese slag using the third cleaning unit 630. This stage aims to thoroughly remove any remaining fine impurities and residues, ensuring the slag's purity. The focus of this process is removing fine particles, dissolved substances, and impurities that may not have been completely removed in the first two cleaning cycles. Alkaline cleaning solutions (such as sodium hydroxide solution) or neutral water are used. Alkaline cleaning solutions help remove some grease, dissolve salts and other organic impurities, while neutral water effectively washes away residual acidic substances and ultimately removes dissolved impurities from the manganese slag, ensuring its purity.

[0052] The filter assembly 300 rotates back and forth under the drive of the rotary seat 200, realizing the reciprocating cycle of feeding, first cleaning, second cleaning, third cleaning, liquid discharge, material discharge, and blowing, so that the material can be continuously filtered.

[0053] Further, please see Figure 2 The discharge mechanism 700 includes bearing seats 720 mounted at both ends of the winch 710, providing stable support points for the winch 710. Furthermore, the discharge mechanism 700 is equipped with drive components 730, which drive the winch 710 to rotate continuously. When the filter disc 310 in the filter assembly 300 moves to the discharge position, the winch 710 is driven by the drive components 730 to rotate under the support of the bearing seats 720 at both ends. As the winch 710 rotates, it effectively removes the manganese slag deposits accumulated in the filter disc 310, ensuring smooth operation of the filtration process.

[0054] The design of the filter assembly 300 also reflects the emphasis on filtration efficiency and effectiveness. The filter disc 310 is designed with a certain depth, which helps to increase the filtration area of ​​the disc 310, thereby improving filtration efficiency. In the structure of the filter disc 310, a portion of the winch 710 is located inside the disc 310. This design allows the winch 710 to directly contact the manganese slag solids in the filter disc 310, thus enabling more efficient removal of the manganese slag solids when the winch 710 rotates. This direct contact and removal method not only improves the removal efficiency of manganese slag but also reduces wear on other mechanical parts, extending the service life of the filter assembly 300.

[0055] Please see Figure 2 In this embodiment, one end of the discharge mechanism 700 is designed to be mounted on the rotary seat 200, while the other end is fixed on the operating platform 100. The structural design of the discharge mechanism 700 allows it to completely cover the radial portion of the filter disc 310. Furthermore, a hopper 110 is specially designed at the end of the discharge mechanism 700 furthest from the filter disc 310. The function of the hopper 110 is to carry away the manganese slag solids through the winch 710 and finally discharge them through the hopper 110 to a designated recycling location for recycling.

[0056] Please see Figure 1 In this embodiment, a driving device 120 is also included, which is disposed in the bottom region of the filter assembly 300. The bottom of the filter assembly 300 is designed with a spaced arrangement and is provided with a plurality of support members 312. These support members 312 are evenly distributed to ensure the stability and support force of the filter assembly 300.

[0057] The drive unit 120 is equipped with drive wheels 121, which contact the support member 312 at the bottom of the filter assembly 300. When the drive unit 120 is started, the drive wheels 121 begin to rotate, thereby causing a relative displacement between the support member 312 and the drive wheels 121, allowing the entire filter assembly 300 to begin rotating based on the rotary seat 200. To further ensure the smooth rotation of the filter assembly 300, this embodiment also features a number of supporting rotation components. These components work closely with the support member 312 to ensure the smooth rotation of the filter assembly 300.

[0058] 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 the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
