Description

Technical Field

[0001] The utility model relates to the technical field of belt filters, and specifically relates to a tension adjusting device for the filter cloth of a belt filter. Background Art

[0002] In modern industrial production, the copper electrolysis purification process is an important link in the copper electrolysis refining process. Its purpose is to purify the electrolyte through a series of technological steps, remove impurities therein, and recover valuable metals, so as to maintain the copper, acid content, and impurity concentration in the electrolyte within the specified range and ensure the normal progress of the electrolysis process. This process is not only crucial for improving the purity of copper products, but also has a significant impact on the efficiency and cost control of the entire production process. During the copper electrolysis purification production process, the purification process is an important link for removing impurities and improving the purity of the solution.

[0003] The purification process usually uses a vacuum belt filter to filter solutions such as copper sulfate, nickel sulfate, and black copper mud. This filter uses the vacuum principle and realizes solid-liquid separation through a belt structure, thereby improving the filtration efficiency and the purity of the solution. During the filtration process, the solution is first concentrated through vacuum evaporation and electro-evaporation, then cooled by a crystallizer, and finally subjected to solid-liquid separation by a belt filter. The solution filtered by the belt filter will enter the next production process to continue the copper reduction and impurity removal treatment. After this continuous process flow, the final solution will be returned to the electrolysis system for recycling, achieving efficient resource utilization and cost reduction.

[0004] However, in the actual production process, problems such as filter cloth slipping, deviation, and cloth tearing easily occur in the belt filter, which will affect the filtration effect, reduce the impurity removal efficiency of the solution, and cause the solution composition to fail to meet the technical requirements. The phenomena of filter cloth slipping and deviation require on-site personnel to frequently stop the machine for maintenance. Moreover, the existing tension cylinders are in a humid environment for a long time and are severely corroded, easily corroded and leaking air. In severe cases, spare parts such as cylinders need to be replaced, increasing the equipment maintenance cost and the labor intensity of on-site personnel. Content of the Utility Model

[0005] The purpose of the utility model is to provide a tension adjusting device for the filter cloth of a belt filter that improves the impurity removal efficiency, is simple to operate, has a high adjustment flexibility, and reduces the maintenance cost, so as to solve the technical problems that the filtration effect is affected due to filter cloth slipping and deviation, the impurity removal efficiency of the solution is reduced, and the equipment maintenance cost is high.

[0006] In order to solve the above technical problems, the following solutions are adopted by the utility model:

[0007] A tension adjustment device for the filter cloth of a belt filter press, comprising a filter press assembly, the filter press assembly including a bracket and a belt filter press body, and further comprising an adjustment assembly; there are two adjustment assemblies, which are respectively installed on both sides of the belt filter press body; the belt filter press body is a prior art, and the adjustment assembly includes a fixing plate, a mounting block, an adjustment block, an adjustment roller and a tensioning device; the bottom end of the fixing plate is fixedly installed at the inner bottom end of the bracket, and the middle of the upper end is connected to one end of the tensioning device, and the tensioning device is limited and supported by the fixing plate; the other end of the tensioning device is connected to the adjustment block; the upper end of the adjustment block is hinged to the mounting block, and one side of the lower end is connected to the adjustment roller; the mounting block is fixedly installed on the middle support side wall of the bracket, and the adjustment block is limited and supported by the mounting block; the adjustment roller is closely attached to the filter cloth of the belt filter press body, and the position of the adjustment block is adjusted by the tensioning devices at both ends of the belt filter press body, and then the position of the adjustment roller is adjusted, and then the tightness of the filter cloth is adjusted.

[0008] Further, the tensioning device includes a main tensioning rod, an auxiliary tensioning rod and a ratchet; one end of the main tensioning rod is hinged to the fixing plate, and the other end is connected to one end of the auxiliary tensioning rod through the ratchet; the other end of the auxiliary tensioning rod is hinged to the other side of the adjustment block; the ratchet is an adjustable ratchet. The main tensioning rod and the auxiliary tensioning rod are rotationally connected by a rotating rod, the ratchet is sleeved on the rotating rod and is fixedly connected to the main tensioning rod, the ratchet is an adjustable ratchet, and its locking pawl is fixed on the auxiliary tensioning rod. By adjusting the angle between the main tensioning rod and the auxiliary tensioning rod, the adjustment block can be driven to rotate relative to the mounting block, thereby adjusting the position of the adjustment roller and changing the shape of the filter cloth to adjust the tension of the filter cloth.

[0009] Further, the tensioning device is provided with an adjustment rod; there are two adjustment rods, which are matched with the adjustment assembly; one end of the adjustment rod is installed at the connection end of the main tensioning rod and the auxiliary tensioning rod. When the filter cloth in the filter press assembly is too tight or too loose, the locking pawl of the ratchet is manually controlled to disengage from the ratchet to cancel the limit of the ratchet, and the adjustment rods of the two side adjustment assemblies are manually lifted, driving the main tensioning rod and the auxiliary tensioning rod to rotate relative to each other to adjust the tightness of the adjustment roller and the filter cloth, and then the position is limited and fixed by the ratchet.

[0010] Further, the tensioning device is provided with a connecting plate; the connecting plate includes connecting plate A and connecting plate B; both ends of connecting plate A are respectively connected to the main tensioning rods of the two adjustment assemblies; both ends of connecting plate B are respectively connected to the auxiliary tensioning rods of the two adjustment assemblies. The adjustment rod can drive the adjustment assemblies on both sides of the belt filter press to move simultaneously through the connecting plate, avoiding the phenomenon that the tension adjustment on both sides of the filter cloth is inconsistent, resulting in the deviation of the filter cloth during circulation. At the same time, only a single operator is required for operation, which is time-saving and labor-saving as a whole.

[0011] Further, the main tension rod and the auxiliary tension rod are made of DN stainless steel pipe; the surface of the adjusting roller is coated with an anti-corrosion coating. The main tension rod and the auxiliary tension rod are made of DN stainless steel pipe, and the anti-corrosion coating on the surface of the adjusting roller can effectively isolate the contact between the roller and the corrosive medium. Both the DN stainless steel pipe and the anti-corrosion coating have good corrosion resistance, especially in harsh environments such as humidity, acid and alkali, they can resist corrosion and extend the service life.

[0012] The working principle of the present utility model is as follows:

[0013] During use, when the filter cloth in the belt filter is too loose, the staff loosens the stop clip of the ratchet, presses the adjusting rod of one side of the adjusting assembly, and drives the tensioning devices on both sides to move simultaneously through the connecting plate. By adjusting the rod, the angle between the main tension rod and the auxiliary tension rod on both sides of the belt filter body is increased, which can drive the adjusting block to rotate relative to the mounting block, thereby adjusting the tightness between the adjusting roller and the filter cloth, so that the filter cloth is in a taut state. After adjustment, it is limited by the ratchet; when the filter cloth in the filter assembly is too tight, the limit is cancelled by controlling the ratchet, and the staff manually lifts the adjusting rod of the adjusting assembly to reduce the angle between the main tension rod and the auxiliary tension rod, thereby adjusting the tightness between the adjusting roller 8 and the filter cloth.

[0014] The beneficial effects of the present utility model are as follows:

[0015] 1. The present utility model controls the rotation of the adjusting roller on the adjusting block relative to the mounting block through the tensioning device, can adjust the shape of the filter cloth, and further effectively adjust the tension of the filter cloth, avoiding phenomena such as slipping, deviation and tearing of the filter cloth due to being too tight or too loose, thereby improving the filtration effect and the impurity removal efficiency of the solution. The overall operation is simple and the adjustment flexibility is high.

[0016] 2. The present utility model adjusts the tension of the filter cloth through the tensioning device, reduces the frequent stops and repairs caused by filter cloth problems, and the overall tensioning devices on both sides can be controlled simultaneously through the connecting plate. A single staff member can operate it, and the tension of the filter cloth can be manually controlled and adjusted, replacing the tensioning of the compression cylinder, reducing the maintenance cost caused by the corrosion and air leakage of the cylinder and the replacement of cylinder and other spare parts.

[0017] 3.

[0027] The working principle of this embodiment is as follows:

[0028] During use, when the filter cloth in the belt filter is too loose, the staff drives the adjusting block to rotate outwards relative to the mounting block through the tensioning devices at both ends of the belt filter body, so that the filter cloth is in a taut state, and then the adjusting roller adjusts the tightness of the filter cloth; when the filter cloth in the filter machine assembly is too tight, the staff drives the adjusting block to rotate inwards relative to the mounting block through the tensioning devices at both ends of the belt filter body, so that the filter cloth is in a relaxed state, and then the adjusting roller adjusts the tightness of the filter cloth, avoiding the phenomenon of the filter cloth shifting during circulation due to relaxation of the filter cloth. Embodiment 2

[0029] The difference from Embodiment 1 is that the tensioning device includes a main tensioning rod 9, an auxiliary tensioning rod 10 and a ratchet 12; one end of the main tensioning rod 9 is hinged to the fixing plate 5, and the other end is connected to one end of the auxiliary tensioning rod 10 through the ratchet 12; the other end of the auxiliary tensioning rod 10 is hinged to the other side of the adjusting block 7; the ratchet 12 is an adjustable ratchet; the tensioning device is provided with an adjusting rod 11; there are two adjusting rods 11, which are matched with the adjusting assembly 4; one end of the adjusting rod 11 is installed at the connection end of the main tensioning rod 9 and the auxiliary tensioning rod 10; the tensioning device is provided with a connecting plate 13; the connecting plate 13 includes a connecting plate A and a connecting plate B; both ends of the connecting plate A are respectively connected to the main tensioning rods 9 of the two adjusting assemblies 4; both ends of the connecting plate B are respectively connected to the auxiliary tensioning rods 10 of the two adjusting assemblies 4; the main tensioning rod 9 and the auxiliary tensioning rod 10 are made of DN32 stainless steel pipe; the surface of the adjusting roller 8 is coated with an anti-corrosion coating.

The main tensioning rod and the auxiliary tensioning rod are rotatably connected by a rotating rod. The ratchet is sleeved on the rotating rod and fixedly connected to the main tensioning rod. The ratchet is an adjustable ratchet, and its pawl is fixed on the auxiliary tensioning rod. By adjusting the angle between the main tensioning rod and the auxiliary tensioning rod, the adjusting block can be driven to rotate relative to the mounting block, thereby adjusting the position of the adjusting roller, changing the shape of the filter cloth to adjust the tension of the filter cloth. The main tensioning rod and the auxiliary tensioning rod are made of DN stainless steel pipe. The anti-corrosion coating on the surface of the adjusting roller can effectively isolate the contact between the roller and the corrosive medium. Both the DN stainless steel pipe and the anti-corrosion coating have good corrosion resistance. Especially in harsh environments such as humidity, acid and alkali, they can resist corrosion and extend the service life.
