Description

Technical Field

[0001] The present invention belongs to the technical field of pressure filtration, and particularly relates to a liquid collecting chute for a filter press. Background Art

[0002] In industries such as chemical engineering, pharmaceuticals, metallurgy, dyes, food, brewing, ceramics, and environmental protection, it is often necessary to separate solid and liquid. To achieve this process, pressure filtration is adopted, and the corresponding equipment is mainly a filter press. During the process of solid-liquid separation by the filter press, both solids and liquids have their respective flow directions. However, due to the diverse and complex pressure filtration media in various industries and the different requirements for pressure filtration effects, the existing settings of solid-liquid flow directions cannot meet the increasingly refined operation requirements. Therefore, it is necessary to optimize part or the whole of this process. The following will elaborate on the deficiencies of the filter press used in zinc hydrometallurgy enterprises:

[0003] During the process of zinc hydrometallurgy, the quality requirements for zinc sulfate solution in the electrowinning operation are extremely high: the impurity content requirements of the solution are Co < 0.0005 g / L, Cd < 0.0010 g / L, Cu < 0.0002 g / L, Ge < 0.00005 g / L, and the chemical composition and physical quality requirements of the solution are relatively high. During the process of pressure filtration and slag discharging, the filter residue is likely to fall into the liquid collecting chute, causing secondary pollution of the filtrate, affecting the solution quality, and thus affecting the electrowinning process.

[0004] In addition, the zinc sulfate solution contains a large amount of calcium and magnesium elements, which are prone to crystallize and precipitate on the pressure filtration equipment, causing blockage and affecting production. The traditional way of guiding the pressure filtrate is as follows: the liquid outlet of the filter plate is connected with a stainless steel short pipe through a threaded connection method, and the stainless steel short pipe is connected with a guiding hose to guide the filtrate into the liquid collecting chute. During the production process, the stainless steel short pipe and the guiding hose are severely crystallized, the cleaning cycle is frequent (cleaned once a week), the labor intensity is high (114 stainless steel short pipes and 114 guiding hoses per filter press), the cleaning difficulty is large (the stainless steel short pipe and the guiding hose need to be disassembled and cleaned one by one, and the liquid collecting chute must be cleaned after each slag discharging), the thread of the liquid outlet of the filter plate is easily damaged during the cleaning process, and the cleaning cost is high (labor cost).

[0005] Therefore, it is necessary to improve the deficiencies existing in the current process of solid-liquid separation by the filter press. Summary of the Invention

[0006] The present invention aims to solve at least one of the technical problems in the related technologies to some extent. For this purpose, an object of the present invention is to provide a liquid collecting chute for a filter press, which has the advantages of strong inclusiveness of pressure filtration media (especially pressure filtration media prone to crystallization), good slag-liquid separation effect, and can effectively avoid secondary pollution of the filtrate.

[0007] In one aspect of the present invention, the present invention provides a liquid collecting chute for a filter press. According to an embodiment of the present invention, the liquid collecting chute for the filter press includes:

[0008] A chute body, the chute body includes a filtrate guiding plate, a chute and a driven gear member. The chute extends along the length direction of the filter press, and a filtrate accommodating space is provided inside the chute. The top of the chute is open to form a liquid inlet. One end of the filtrate guiding plate is arranged on the edge of the liquid inlet, and the other end of the filtrate guiding plate is detachably arranged on the filter press. The driven gear member is arranged on the outer peripheral wall of the chute, and a liquid outlet is provided on the chute;

[0009] A chute steering transmission assembly, the chute steering transmission assembly includes a rotating assembly and a transmission shaft. The rotating assembly is connected to one end of the transmission shaft to drive the transmission shaft to rotate. A driving gear member is provided on the outer peripheral wall of the transmission shaft, and the driving gear member meshes with the driven gear member;

[0010] A chute support base, the chute support base includes a first support base and a second support base. The first support base and the second support base are respectively arranged at both ends of the chute. Support bearing assemblies are respectively provided on the first support base and the second support base. The chute is arranged on the support bearing assemblies and can rotate along the support bearing assemblies. A first limiting member and a transmission shaft braking member are provided on the first support base. A second limiting member is provided on the second support base. The transmission shaft sequentially passes through the first limiting member and the second limiting member, and the transmission shaft can rotate along the first limiting member and the second limiting member. The transmission shaft braking member is sleeved on the transmission shaft to brake the transmission shaft.

[0011] The liquid collecting chute of a filter press according to an embodiment of the present invention includes a chute body, a chute steering transmission assembly, and a chute support base. Among them, the chute body includes a filtrate diversion plate, a chute, and a driven gear member. The chute extends along the length direction of the filter press, and a filtrate accommodation space is provided inside the chute. The top of the chute is open to form a liquid inlet. One end of the filtrate diversion plate is provided on the edge of the liquid inlet, and the other end of the filtrate diversion plate is detachably provided on the filter press. The driven gear member is provided on the outer peripheral wall of the chute, and a liquid outlet is provided on the chute; the chute steering transmission assembly includes a rotating assembly and a transmission shaft. The rotating assembly is connected to one end of the transmission shaft to drive the transmission shaft to rotate. A driving gear member is provided on the outer peripheral wall of the transmission shaft, and the driving gear member meshes with the driven gear member; the chute support base includes a first support base and a second support base. The first support base and the second support base are respectively provided at both ends of the chute. Support bearing assemblies are respectively provided on the first support base and the second support base. The chute is provided on the support bearing assemblies and can rotate along the support bearing assemblies. A first limiting member and a transmission shaft braking member are provided on the first support base. A second limiting member is provided on the second support base. The transmission shaft sequentially passes through the first limiting member and the second limiting member, and the transmission shaft can rotate along the first limiting member and the second limiting member. The transmission shaft braking member is sleeved on the transmission shaft to brake the transmission shaft. When the filter press performs a filtrate operation, the transmission shaft is braked by the transmission shaft braking member, so that the other end of the filtrate diversion plate is connected to the side of the filtrate outlet of the filter plate of the filter press (as Figure 4 shown), and the filtrate flowing out of the filtrate outlet of the filter plate of the filter press can enter the chute from the liquid inlet of the chute along the filtrate diversion plate. The filtrate diversion plate can effectively solve the problem of crystallization blockage caused by using stainless steel short pipes or diversion hoses. The filtrate in the chute flows out from the liquid outlet of the chute; when the filter press completes the filtrate operation, before performing the slag discharging operation on it, first release the restriction of the transmission shaft braking member on the transmission shaft, and then apply power to the rotating assembly. The driving gear member is driven to rotate by the transmission shaft. Under the operation of gear engagement, the driven gear member rotates, driving the chute to rotate. After deflecting the chute away from the filter press by a certain angle, the transmission shaft is braked by the transmission shaft braking member, so that the bottom of the chute is close to the filtrate outlet of the filter plate of the filter press, and the liquid inlet of the chute is far from the filtrate outlet of the filter plate of the filter press (as Figure 5 shown). At this time, when performing the slag discharging operation of the filter press, it can be avoided that the filter residue in the filter press falls into the chute through the liquid inlet of the chute, effectively avoiding secondary pollution of the filtrate. In summary, the liquid collecting chute of the filter press of the present application can ensure the effective isolation of the filter residue during the slag discharging process of the filter press, avoid secondary pollution of the filtrate, ensure the cleanliness of the filtrate, have strong inclusiveness for the filter medium (especially the easily crystallized filter medium), cancel the external stainless steel short board and the diversion hose, have a simple mechanical structure, and eliminate the installation, crystallization blockage cleaning, maintenance and other work of the external short pipe, which is beneficial to the enterprise to save energy and reduce consumption and improve economic benefits.

[0012] In addition, the liquid collecting chute of the filter press according to the above embodiments of the present invention may further have the following additional technical features:

[0013] In some embodiments of the present invention, the chute is cylindrical, and the longitudinal section of the chute is a fan surface of 1 / 2 to 3 / 4. Thus, on the one hand, the filtrate accommodating space can accommodate more filtrate; on the other hand, it is beneficial to completely guide the filtrate into the filtrate accommodating space of the chute.

[0014] In some embodiments of the present invention, first baffles are provided on both sides of the filtrate guiding plate perpendicular to the axial direction of the chute. Thus, it is beneficial to completely guide the filtrate into the filtrate accommodating space of the chute.

[0015] In some embodiments of the present invention, a second baffle is provided at the other end of the filtrate guiding plate. Thus, it can prevent the filtrate from flowing back.

[0016] In some embodiments of the present invention, the transmission shaft braking member includes a braking clip, a rotatable braking card slot, a support shaft, and a braking assembly. Among them, the braking clip is provided on the transmission shaft, the rotatable braking card slot is sleeved on the support shaft, and the braking assembly is provided on the rotatable braking card slot and drives the rotatable braking card slot to rotate, so that the rotatable braking card slot is sleeved with and separated from the braking clip to brake and unrestrict the transmission shaft. Thus, the chute can stay at any deflection angle within a certain accuracy and within a certain range.

[0017] In some embodiments of the present invention, the support shaft is provided on the first support base.

[0018] In some embodiments of the present invention, the transmission shaft braking member includes a plurality of the braking clips, and the plurality of braking clips are arranged at intervals along the outer peripheral wall of the transmission shaft.

[0037] In one aspect of the present invention, the present invention provides a liquid collecting chute for a filter press. According to an embodiment of the present invention, the liquid collecting chute for the filter press includes: a chute body, a chute steering transmission assembly, and a chute support base.

[0038] According to some embodiments of the present invention, referring to Figures 1-3, the chute body includes a filtrate diversion plate 11, a chute 12, and a driven gear member 13. The chute 12 extends along the length direction of the filter press 100, and a filtrate accommodation space is provided inside the chute 12. The top of the chute 12 is open to form a liquid inlet 14. One end of the filtrate diversion plate 11 is arranged on the edge of the liquid inlet 14, and the other end of the filtrate diversion plate 11 is detachably arranged on the filter press 100 and is adapted to guide the filtrate flowing out of the liquid outlet of the filter plate of the filter press 100 into the filtrate accommodation space of the chute 12 through the filtrate diversion plate 11. The driven gear member 13 is arranged on the outer peripheral wall of the chute 12, and a liquid outlet 15 is provided on the chute 12. It should be noted that those skilled in the art can select the specific types of the filtrate diversion plate 11, the chute 12, and the driven gear member 13 according to actual needs, as long as the above functions can be achieved. For example, the chute 12 is cylindrical. Further, the longitudinal section of the chute 12 is a fan surface of 1 / 2 to 3 / 4. Thus, on the one hand, the filtrate accommodation space can accommodate more filtrate; on the other hand, it is beneficial to completely guide the filtrate into the filtrate accommodation space of the chute 12. Further, referring to Figure 8 , first baffles 16 are provided on both sides of the filtrate diversion plate 11 perpendicular to the axial direction of the chute 12. Thus, it is beneficial to completely guide the filtrate into the filtrate accommodation space of the chute 12. Further, referring to Figure 8 , a second baffle 17 is provided on the other end of the filtrate diversion plate 11. The inventor found that the liquid flow rate at the liquid outlet of the filter plate of the filter press 100 is fast, and there will be splashing solution backward. By providing the second baffle 17 on the other end of the filtrate diversion plate 11, the backflow of the filtrate can be prevented. Further, the liquid outlet 15 is arranged at the lowest end of the chute 12. Thus, it is convenient to export the filtrate in the chute 12.

[0039] According to some embodiments of the present invention, referring to Figures 1-3 , the chute turning transmission assembly includes a rotating assembly 21 and a transmission shaft 22. The rotating assembly 21 is connected to one end of the transmission shaft 22 to drive the transmission shaft 22 to rotate. A driving gear member 23 is provided on the outer peripheral wall of the transmission shaft 22. The driving gear member 23 meshes with the driven gear member 13 and is adapted to apply power to the rotating assembly 21, drive the driving gear member 23 to rotate through the transmission shaft 22. Under the operation of gear engagement, the driven gear member 13 operates to drive the chute 12 to rotate. It should be noted that those skilled in the art can select the specific types of the rotating assembly 21, the transmission shaft 22, and the driving gear member 23 according to actual needs. For example, the rotating assembly 21 is a disc handwheel.

[0040] According to some embodiments of the present invention, referring to Figure 3, the chute support base includes a first support base 31 and a second support base 32. The first support base 31 and the second support base 32 are respectively arranged at both ends of the chute 12 and are adapted to bear the overall load of the device. Support bearing assemblies 33 are respectively provided on the first support base 31 and the second support base 32. The chute 12 is arranged on the support bearing assemblies 33 and can rotate along the support bearing assemblies 33. A first limiting member 34 is provided on the first support base 31, and a second limiting member 35 is provided on the second support base 32. The transmission shaft 22 sequentially passes through the first limiting member 34 and the second limiting member 35, and the transmission shaft 22 can rotate along the first limiting member 34 and the second limiting member 35, so that the transmission shaft 22 can be kept in a relatively fixed position without affecting the rotation of the transmission shaft 22. A transmission shaft braking member 36 is also provided on the first support base 31. The transmission shaft braking member 36 is sleeved on the transmission shaft 22 to brake the transmission shaft 22. Thus, it can be ensured that when the filter press is performing filtrate operation and slag discharging operation, the chute 12 is restricted to the required deflection angle. It should be noted that those skilled in the art can select the specific types of the first support base 31, the second support base 32, the support bearing assembly 33, the first limiting member 34, the second limiting member 35, and the transmission shaft braking member 36 according to actual needs, as long as the above functions can be realized.

[0041] Further, referring to Figures 1-2 , each support bearing assembly 33 includes two rolling bearings. The two rolling bearings are respectively located on both sides of the axis of the chute 12. The inner rings of the rolling bearings are fixed to the chute support base through brackets, and the outer rings can rotate freely and are adapted to reduce friction and wear during the rotation of the chute 12.

[0042] Further, referring to Figures 6-7 , the transmission shaft braking member 36 includes a braking clip 361, a rotatable braking slot 362, a support shaft 363, and a braking assembly 364. Among them, the braking clip 361 is arranged on the transmission shaft 22, the rotatable braking slot 362 is sleeved on the support shaft 363, and the braking assembly 364 is arranged on the rotatable braking slot 362 and drives the rotatable braking slot 362 to rotate, so that the rotatable braking slot 362 is sleeved with and separated from the braking clip 361 to brake and unrestrict the transmission shaft 22. Specifically, the support shaft 363 is arranged on the first support base 31. Further, the transmission shaft braking member 36 includes a plurality of braking clips 361. The plurality of braking clips 361 are arranged at intervals along the outer peripheral wall of the transmission shaft 22, and the braking clips 361 are perpendicular to the transmission shaft 22, so that the chute 12 can stay at any deflection angle within a certain accuracy and within a certain range.

[0043] Further, referring to Figure 3, the first support base 31 is provided at one end of the chute 12 close to the rotating assembly 21, and the driven gear member 13 is provided between the first support base 31 and the second support base 32 and close to the first support base 31. Thus, the deflection of the chute 12 can be achieved more labor - savingly by using the chute steering transmission assembly.

[0044] The inventor found that the liquid - collecting chute of the filter press of the present application includes a chute body, a chute steering transmission assembly, and a chute support base. Among them, the chute body includes a filtrate diversion plate, a chute, and a driven gear member. The chute extends along the length direction of the filter press, and a filtrate accommodation space is provided inside the chute. The top of the chute is open to form a liquid inlet. One end of the filtrate diversion plate is provided on the edge of the liquid inlet, and the other end of the filtrate diversion plate is detachably provided on the filter press. The driven gear member is provided on the outer peripheral wall of the chute, and a liquid outlet is provided on the chute; the chute steering transmission assembly includes a rotating assembly and a transmission shaft.

When the filter press performs a filtrate operation, the transmission shaft braking member is used to brake the transmission shaft, so that the other end of the filtrate diversion plate is connected to the side of the liquid outlet of the filter plate of the filter press (as Figure 4 shown). The filtrate flowing out from the liquid outlet of the filter plate of the filter press can enter the chute from the liquid inlet of the chute along the filtrate diversion plate.
