[0002] Electrolytic manganese residue is a kind of solid waste generated in the production process of electrolytic manganese, and its main components are manganese oxide, silicate and other impurity particles. Before further processing or resource utilization, such materials usually need to go through pretreatment processes such as washing and filtering to remove residual acid liquid and other impurities. However, due to the characteristics of fine particles, high moisture content and easy adhesion of electrolytic manganese residue, there are many technical problems in the washing and filtering process. For example, the traditional filtering equipment lacks clear division of operation areas, and the processes such as feeding, filtering, washing and unloading interfere with each other, resulting in an unsmooth operation process and affecting the overall operation efficiency. The high viscosity and high density characteristics of electrolytic manganese residue can easily lead to uneven distribution of materials on the filter disc, reducing the filtering efficiency and making the washing and unloading process more complex. The adaptability of traditional equipment to high-viscosity materials is poor, and problems such as equipment vibration, blockage and filter disc damage may occur during operation, affecting the service life and running stability of the equipment.

[0029] Embodiment 1

[0030] Please refer to Figure 1The utility model embodiment provides a kind of for electrolytic manganese residue washing's turnover disc type filter, in prior art, traditional plate-and-frame or diaphragm filter press these traditional equipment is generally applicable to single filtration process flow, but when dealing with stubborn impurities in manganese residue, especially those residual chemicals, they are often difficult to remove completely by single pressure washing.When plate-and-frame and diaphragm filter press are used to handle high water content, electrolytic manganese residue with complex composition, they are prone to encounter a common problem, that is, filter cloth blockage.This blockage phenomenon can cause equipment to need to be cleaned frequently, thereby affecting the efficiency of continuous operation.In addition, existing filter equipment often lacks clear work area division, which leads to confusion or inconvenience when operating between different processes.This confusion not only makes unnecessary interference between processes, but also limits the washing effect, ultimately resulting in low overall filtration efficiency.

[0031] Therefore, in the embodiment, a turnover disc type filter is proposed to improve the working efficiency in the process of handling electrolytic manganese residue filtration.In the embodiment, the turnover disc type filter includes a support mechanism composed of a rotating seat 110 and a plurality of support frames 120.The main function of the support mechanism is to provide stable support for other components to ensure that other working parts can work in a stable environment.The rotating seat 110 is designed to rotate, and the support mechanism also assists the rotating task of the working parts, thereby ensuring that the working parts can rotate in a relatively stable manner when performing filtration operations.

[0032] Further, the rotating seat 110 of the filter device is specially provided with a rotating frame 130 connected thereto;The rotating frame 130 and the rotating seat 110 are tightly combined through a fixed connection mode, to ensure that the rotating frame 130 can rotate synchronously with the rotating seat 110.The presence of the rotating frame 130 provides a reliable connection point for the working parts, so that the working parts can stably rotate with the rotating seat 110.Such a setting makes the entire filtration work process proceed smoothly, ensuring filtration efficiency and effect.

[0033] Further, the rotating frame 130 is connected to the support frame 120 through the support plate 131, which is not only stable but also facilitates installation and disassembly. Between the rotating frame 130 and the support frame 120, sufficient space is provided to facilitate the installation of various working components to meet different working requirements. In addition, the rotating frame 130 is designed to be flexible in actual application, and the connection through the support plate 131 makes the entire structure more stable and facilitates the installation of working components. The rotating base 110 and the support frame 120 are both arranged in a ring shape, which allows the rotating base 110 to rotate easily, thereby providing the necessary rotation conditions for the filtering process. The ring structure not only ensures smooth rotation, but also ensures filtering efficiency and effectiveness.

[0034] Referring to Figure 1 In this embodiment, a working component, i.e., a filtering assembly 200, is provided between the support frame 120 and the rotating frame 130. The main function of the filtering assembly 200 is to complete the filtering operation of specific materials, such as electrolytic manganese residue. The filtering operation is not limited to a single filtering process, but actually includes two main parts: washing and filtering. In addition, the filtering assembly 200 is responsible for related operations such as feeding and unloading to ensure smooth progress of the entire filtering process.

[0035] In the arrangement of the filtering assembly 200, a plurality of filter discs 210 are used, which are arranged at uniform angular intervals to ensure uniformity and efficiency of the filtering process. All material filtering operations are carried out in these filter discs 210, thereby ensuring the consistency of filtering quality. Each filter disc 210 is formed by surrounding and fixing a filter cloth with at least three filter plates 211, thereby forming a closed filtering cavity.

[0036] Referring to Figure 1 In this embodiment, the filter disc 210 surrounds the filter cloth with four filter plates 211 to form a trapezoidal-shaped filtering cavity. The design of the filter disc 210 not only facilitates material filtering, but also facilitates subsequent cleaning work. The cleaning mechanism is designed to thoroughly clean the material residues or filter cloth in the filtering cavity to ensure the continuous and efficient operation of the filtering assembly 200.

[0037] In this embodiment, one end of the filter disc 210 is connected to the rotating frame 130 by hinging, and the other end is connected to the support frame 120. This connection allows the filter disc 210 to perform self-rotation, thereby effectively performing the turnover unloading operation to achieve efficient unloading.

[0038] In addition, the design of the support frame 120 is not limited to the supporting function, and the support frame 120 is also equipped with a cleaning mechanism 300 to ensure that the material and the filter disc 210 can be kept clean during the work process. The cleaning mechanism 300 at least includes two main parts, i.e., a first cleaning part and a second cleaning part. The main function of the first cleaning part is to clean the material in the filter disc 210.

[0039] In order to improve the cleaning effect of the material in the filter disc 210, the first cleaning part is arranged to include at least two stages of cleaning process. After the material enters the filter disc 210, due to the filtering effect of the filter disc 210, the material will gradually form a filter cake in the filter disc 210. With the driving of the rotating seat 110, the filter assembly 200 will perform a revolution motion, which can sequentially transfer the filter cake to different washing stages, thereby completing the thorough washing of the material. In this way, the filter disc 210 can maintain a high-efficiency working state, while ensuring the cleanliness of the material, meeting the high-standard requirements in industrial production.

[0040] The second cleaning part is used to clean the filter cloth of the filter disc 210 after the unloading is completed, so as to avoid the filter cloth being blocked, resulting in poor efficiency and quality of the subsequent filtering operation. When the filter disc 210 completes the process of feeding, washing, filtering and unloading once, the filter cloth of the filter disc 210 is cleaned. By periodically cleaning the filter cloth, the filter cloth is prevented from being blocked, and the continuous and stable operation of the equipment is ensured. After the filter disc 210 is self-rotated to flip and unload the filter cake, the filter cloth can better contact the cleaning liquid during the washing process.

[0041] Please refer to Figure 2 The filter assembly 200 is arranged between the rotating seat 110 and the support frame 120 as a plurality of working zones; the working zones at least include a cleaning zone, a filtering zone, a feeding zone 450 and an unloading zone 460; the rotating seat 110 drives the filter disc 210 to rotate and pass through the working zones.

[0042] The cleaning zone at least includes a first cleaning zone 410, a second cleaning zone 420 and a third cleaning zone 430; the first cleaning zone 410 and the second cleaning zone 420 are arranged adjacently and are arranged at the top of the filter assembly 200; and the third cleaning zone 430 is arranged at the bottom of the filter assembly 200.

[0043] The first cleaning part is used to perform step-by-step cleaning of the material in the filter disc 210 in the first cleaning zone 410 and the second cleaning zone 420; and the second cleaning part is used to clean the filter cloth in the third cleaning zone 430.

[0044] The first cleaning part is provided with a cleaning pipeline and a plurality of cleaning nozzles; the cleaning pipeline covers the range of the filter disc 210 in the first cleaning area 410 and the second cleaning area 420, and the material in the filter disc 210 is washed by the cleaning nozzles when the filter assembly 200 rotates and passes through the first cleaning area 410 and the second cleaning area 420.

[0045] Further, referring to Figure 2 , the filter area includes a first filter area 441 and a second filter area 442, and the filter area and the cleaning area are arranged in pairs and adjacent to each other. The arrangement sequence is generally first cleaning area 410, first filter area 441, second cleaning area 420, and second filter area 442; after the material is cleaned once, the material is filtered for a period of time, so that the moisture and impurities in the material are discharged through the filter screen. When the filter area is arranged, sufficient filtering time is arranged so that the moisture and impurities in the material can be fully discharged after each cleaning.

[0046] The material (electrolytic manganese slag) starts a multi-stage filtering and washing process after entering the filter cavity. The material is distributed to each filter disc 210, and the large-particle impurities are removed after being cleaned in the first cleaning area 410 and filtered in the first filter area 441. The chemical residues and stubborn impurities of the material are removed after being cleaned in the second cleaning area 420 and filtered in the second filter area 442.

[0047] In this embodiment, the chemical residues and stubborn impurities of the material are gradually removed by staged washing. The multi-washing design is more thorough than the single-pressure washing of the traditional plate and frame filter press and diaphragm filter press.

[0048] The bottom of the filter area and the cleaning area is provided with a waste liquid recovery bin for collecting the cleaning liquid and the filtered waste water.

[0049] Further, referring to Figure 1 and Figure 2 , in order to realize that the filter assembly 200 can rotate with the rotation of the rotating seat 110, a plurality of support frames 120 are arranged at uniform angular intervals, and a revolution track 140 is further arranged through the plurality of support frames 120; a plurality of sliding seats 150 are arranged on the revolution track 140; one end of each filter disc 210 is hinged to one sliding seat 150. So that the filter assembly 200 can rotate. When rotating, the sliding seat 150 slides on the revolution track 140 with the rotation of the rotating seat 110, so that the filter assembly 200 realizes stable rotation.

The pulleys 152 are used to realize contact and sliding with the orbit 140. The sliding carrier 151 is hingedly connected with the filter disc 210, so that the filter disc 210 can realize rotation between the rotating frame 130 and the support frame 120 to complete the unloading operation.

[0051] Further, please refer to Figure 2 and Figure 3 After the filter disc 210 is added with materials, the filter disc 210 may be overturned due to the instability of the materials in the filter disc 210, so that the materials may be unloaded in a region other than the unloading area 460; therefore, the bottom of the filter assembly 200 is further provided with an auxiliary support part 160 for assisting in supporting the stable operation of the filter disc 210 and assisting in the rotation of the filter assembly 200; the auxiliary support part 160 comprises a plurality of support seats 161 and slide rails 163 arranged on the support seats 161, and the support seats 161 are provided with rotatable auxiliary wheels 162; the slide rails 163 move through the auxiliary wheels 162 on the support seats 161. The support frame 120 is in contact with the slide rails 163 through the auxiliary wheels 162; the slide rails 163 rotate with the rotation of the filter assembly 200; and both ends and the middle part of the filter disc 210 are provided with the support seats 161. However, the support seats 161 are not arranged in the unloading area 460, so as to facilitate the unloading of the materials.

[0053] Please refer to Figure 1When rotating, the filter assembly 200 rotates by starting the rotating seat 110; the rotating seat 110 can be driven by a motor and other driving components, and the rotating speed is controlled by a speed reducer or other speed regulating mechanism. After the filter assembly 200 rotates, the filter disc 210 sequentially passes through different areas. First, the filter disc 210 realizes the addition of the material in the feeding area 450, then rotates to the first cleaning area 410 to perform the first washing, then passes through the first filtering area 441 to perform the preliminary filtering; then passes through the second cleaning area 420 to perform the cleaning, and then passes through the second filtering area 442 to perform the second filtering; then enters the discharging area 460, and the self-rotation of the filter disc 210 is reversed to realize the discharging, and then the filter disc 210 and the filter cloth are cleaned by the third cleaning area 430; thus, a cycle of work is completed; through continuous cycle work, the filtering work of the material is realized.
