Description

Technical Field

[0001] The present invention belongs to the technical field of pulp distribution and relates to a pulp distribution device for mineral processing. Background Art

[0002] The pulp involved in fields such as mineral processing and hydrometallurgy is a heterogeneous solid-liquid suspension mainly composed of mineral particles and water. The preparation and treatment process of pulp mainly includes steps such as stirring, solid-liquid separation, and washing. These steps usually involve pulp distribution, that is, quantitatively distributing the pulp into different mineral processing equipment or processes. Therefore, the pulp distribution operation is of great significance for ensuring the mineral processing efficiency and product quality.

[0003] The pulp distributor is one of the core equipment used in the mineral processing process. The pulp distributor is usually designed based on the principles of gravity and liquid dynamics. Generally, the pulp is input into the collector of the pulp distributor through the feed port, and then through the nozzle and the deflector, quantitative distribution is achieved according to the principles of liquid dynamics. The design of the deflector is used to adjust the flow rate and direction of the pulp.

[0004] The Chinese utility model with the authorization announcement number CN218859794U discloses "a pulp distributor for mineral processing", which relates to the technical field of pulp distribution devices. It includes a pulp pool. A plurality of discharge pipes are fixedly connected to the bottom wall of the pulp pool. A support ring is fixedly connected to the side wall of the supply pipe. A plurality of support plates are fixedly connected between the support ring and the side wall of the pulp pool. The lower end surface of the support plate is fixedly connected with a support cylinder. A transmission rod is arranged inside the support cylinder. A motor is installed on the upper end surface of the support plate. The output shaft of the motor penetrates the support plate and is fixedly connected with the transmission rod through a coupling. The lower end of the transmission rod extends into the discharge pipe and is fixedly connected with a stirring plate. It drives the transmission rod to rotate through the motor, the transmission rod drives the stirring plate to rotate, and the stirring plate rotates in the discharge pipe to stir the pulp, thereby preventing the discharge pipe from being blocked by the pulp and ensuring the stable operation of the subsequent equipment.

[0005] Traditional pulp distribution devices including the above-mentioned utility model can only ensure that the pulp is evenly distributed into each sorting tank during rotary feeding. However, the particle size distribution of the mineral particles contained in the pulp is uneven. The uneven distribution of mineral particles in the pulp will cause the mineral concentration in some areas to be too high while too low in other areas. This will affect the processing effect of the mineral processing equipment and have an impact on the subsequent smelting process. Summary of the Invention

[0006] The purpose of the present invention is to provide a pulp distribution device for mineral processing, which realizes the synchronous and uniform distribution of pulp and particles through rotary centrifugal dispersion combined with double-stage filtration, so as to solve the technical problems proposed in the background art.

[0007] To solve the above technical problems, the present invention provides the following technical solutions: A pulp distribution device for ore dressing, comprising a fixed distribution bin and a driving motor. The fixed distribution bin has a first accommodating groove with an open upper end and connected with a feed pipe. An active distribution bin is installed in the first accommodating groove, and the active distribution bin has a second accommodating groove with an open upper end. A base is arranged on the inner bottom side of the first accommodating groove, and a connecting shaft is installed in the base. The driving motor is in transmission connection with the connecting shaft. The active distribution bin is in transmission connection with the connecting shaft through a transmission rod. A distribution boss is fixedly installed in the second accommodating groove, and a plurality of inclined plates are circumferentially and evenly arranged on the surface of the distribution boss. A plurality of first discharge pipes are connected to the outer side surface of the active distribution bin, and the inner and outer ends of the first discharge pipes are respectively communicated with the second accommodating groove and the first accommodating groove. A plurality of side plates with inner ends connected to the base are circumferentially and evenly installed in the first accommodating groove. A groove bottom plate is arranged between two adjacent side plates, and a fine filter plate and a coarse filter plate located above the groove bottom plate are installed between two adjacent side plates. The fine filter plate is located outside the coarse filter plate, and the coarse filter plate and the fine filter plate are on the same inclined plane with gradually decreasing height from inside to outside. The groove bottom plate is provided with through holes, and the through holes are inlaid with second discharge pipes.

[0008] Preferably, a motor cover that covers the driving motor is installed on the outer bottom side of the active distribution bin.

[0009] Preferably, a connecting shaft provided with a cross groove is installed in the base; the driving motor is installed on the outer bottom side of the first accommodating groove, the output end of the driving motor is connected with a driving shaft, the driving shaft penetrates into the fixed distribution bin and is connected with the connecting shaft; the lower end of the active distribution bin is fixedly connected with a transmission rod and the transmission rod is provided with a cross plug board, and the cross plug board of the transmission rod is inserted into the cross groove to realize the transmission connection between the connecting shaft and the active distribution bin.

[0010] Preferably, the inclination direction of the inclined plate is the same as the rotation direction of the active distribution bin; the included angle between the inclined plate and the horizontal plane is 30° - 60°.

[0011] Preferably, the included angle between the inclined plane and the horizontal plane is 10° - 20°.

[0012] Preferably, a pipe sleeve is installed at the central position inside the second accommodating groove, and the pipe sleeve is fixedly connected to the groove wall of the second accommodating groove through a fixing rod; one end of the feed pipe passes through the pipe sleeve and is located directly above the distribution boss.

[0013] Preferably, a limit seat is installed on the bin wall of the fixed distribution bin; a limit groove with a radial direction is opened inside the limit seat, and a limit plate capable of sliding radially along the limit groove is installed in the limit groove; after the transmission rod is connected with the connecting shaft, the upper end of the active distribution bin is located below the limit plate.

[0014] Further preferably, a limiting sliding groove with a radial direction and communicating with the limiting groove is also formed on the upper side of the limiting seat; a sliding block is slidably installed in the limiting sliding groove, a limiting plate is connected to the lower end of the sliding block, and a dial block is connected to the upper end.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: First, the present invention provides a movable distribution bin with a distribution boss and a fixed distribution bin with a filtering groove. After the pulp mixed with mineral particles enters the first accommodating groove, starting the driving motor can drive the movable distribution bin to rotate. The distribution boss and the inclined plate in the movable distribution bin evenly disperse the pulp. The evenly dispersed pulp is conveyed into the first accommodating groove along the first discharge pipe. Since the movable distribution bin is in a rotating state, the pulp can maintain an evenly dispersed state due to centrifugal force, and thus is evenly distributed to each filtering groove. Since the filtering groove is equipped with a fine filter plate and a coarse filter plate, an approximately equal amount of mineral particles evenly seeps into each filtering groove, thereby preventing the uneven mixing of mineral contents in different filtering grooves. The synchronous and uniform distribution of the pulp and the particles is realized.

[0016] Second, the present invention provides a limiting seat with a limiting plate. After installing the movable distribution bin in the fixed distribution bin, the limiting plate can be pushed inward from the limiting groove through the dial block and the sliding block, so that the limiting plate is located above the movable distribution bin, thereby providing a limiting measure for the rotating movable distribution bin and further improving the safety of the equipment.

[0017] Third, in the present invention, through the rotation of the movable distribution bin, the inclined plate evenly throws the pulp tangentially, and combines with centrifugal force to offset gravity sedimentation, ensuring the fluidity of the pulp and better realizing the dynamic centrifugal dispersion of the pulp.

[0018] Fourth, the present invention adopts a two-stage filtration design. The fine filter plate intercepts fine particles, and the coarse filter plate blocks larger particles. The two are arranged in a stepped manner to prevent blockage and balance the particle concentration at the bottom plate of each tank.

[0019] Fifth, the present invention has self-adaptive limiting. The limiting plate is dynamically adjusted through the sliding block to adapt to the rotation and vibration of the movable distribution bin, improving the operating stability of the equipment. Description of the Drawings

Detailed implementation manners

[0022] The present invention will be described in detail below in conjunction with embodiments and drawings.

[0023] As Figure 1 , Figure 3 and Figure 4 shown, an embodiment of the pulp distribution device of the present invention includes a fixed distribution bin 1 and a movable distribution bin 10 installed in the fixed distribution bin 1. The fixed distribution bin 1 has a first receiving groove 2 with an open upper end, and the movable distribution bin 10 has a second receiving groove 11 with an open upper end. A plurality of support frames 24 are fixedly connected to the outer peripheral side of the fixed distribution bin 1 to support the device.

[0024] A base 3 is arranged on the inner bottom side of the first receiving groove 2, and a connecting shaft 4 provided with a cross groove 5 is installed in the base 3. A driving motor 7 is installed on the outer bottom side of the first receiving groove 2, and the output end of the driving motor 7 is connected to a driving shaft 8. The driving shaft 8 penetrates into the fixed distribution bin 1 and is connected to the connecting shaft 4. The lower end of the movable distribution bin 10 is fixedly connected to a transmission rod 9 with a cross plug board, and the cross plug board of the transmission rod 9 is inserted into the cross groove 5 to realize the transmission connection between the connecting shaft 4 and the movable distribution bin 10. When the driving motor 7 works, the connecting shaft 4 is driven to rotate by the driving shaft 8, and the connecting shaft 4 drives the movable distribution bin 10 to rotate through the transmission rod 9.

[0025] Furthermore, a motor cover 6 that covers the driving motor 7 inside is installed on the outer bottom side of the movable distribution bin 10.

[0026] A distribution boss 12 is fixedly installed in the second receiving groove 11. A plurality of inclined plates 13 are circumferentially and uniformly arranged on the surface of the distribution boss 12. The angle between the inclined plate 13 and the horizontal plane is preferably 30°-60°. The inclination direction of the inclined plate 13 is preferably the same as the rotation direction of the movable distribution bin 10 to optimize the pulp dispersion trajectory. A plurality of first discharge pipes 16 are connected to the outer side surface of the movable distribution bin 10, and the inner and outer ends of the first discharge pipe 16 communicate with the second receiving groove 11 and the first receiving groove 2 respectively.

[0027] Combined with Figure 2 and Figure 5 , a plurality of side plates 27 are circumferentially and uniformly installed in the first receiving groove 2, and the inner ends of the side plates 27 are connected to the base 3. A bottom plate 28 is arranged between two adjacent side plates 27, and a filter frame plate 29 is installed above the bottom plate 28 between two adjacent side plates 27. A fine filter plate 30 with a pore diameter of 0.1-0.5 mm and a coarse filter plate 31 with a pore diameter of 1-2 mm are installed on the filter frame plate 29. The fine filter plate 30 is located outside the coarse filter plate 31, and the coarse filter plate 31 and the fine filter plate 30 are on the same inclined plane with the height gradually decreasing from the inside to the outside. The angle between the inclined plane and the horizontal plane is preferably set to 10°-20°. Two adjacent side plates 27, the bottom plate 28 between two adjacent side plates 27, and the coarse filter plate 31 and the fine filter plate 30 above the bottom plate 28 form a filtering groove.

[0028] Specifically, mounting screw holes 32 are formed in the side part of the filter frame plate 29, and screws passing through the mounting screw holes 32 are driven into the upper end surface of the corresponding side plate 27 to realize the fixed connection between the filter frame plate 29 and the side plate 27.

[0029] The bottom plate 28 is provided with a through hole 17, and a second discharge pipe 33 is inlaid and installed in the through hole 17.

[0030] A pipe sleeve 15 is installed at the central position inside the second receiving groove 11, and the pipe sleeve 15 is fixedly connected to the groove wall of the second receiving groove 11 through a fixing rod 14.

[0031] An embodiment of the pulp distribution device of the present invention further includes a feed pipe 25. The feed pipe 25 includes a vertical section and a horizontal section that are at a 90° angle to each other and are connected to each other. The outer end of the vertical section passes through the pipe sleeve 15 and is located directly above the distribution boss 12, and the outer end of the horizontal section is connected with a flange 26. The pipe sleeve 15 is used to support and fix the feed pipe 25, and the inner diameter of the pipe sleeve 15 is slightly larger than the outer diameter of the vertical section of the feed pipe 25. The flange 26 is used to connect the feed pipe.

[0032] Further, a limit seat 18 is also installed on the wall of the fixed distribution bin 1. A limit groove 22 with a radial direction is formed inside the limit seat 18, and a limit plate 23 capable of sliding radially along the limit groove 22 is installed in the limit groove 22. After the cross-shaped insertion plate of the transmission rod 9 is inserted into the cross-shaped groove 5, the upper end of the movable distribution bin 10 is located below the limit plate 23. After the limit plate 23 slides inwards to the in-place position, the inner end is located above the wall of the movable distribution bin 10 and is used to limit the axial position of the movable distribution bin 10, so as to prevent the cross-shaped insertion plate of the transmission rod 9 from being disengaged from the cross-shaped groove 5 when the movable distribution bin 10 moves upwards.

[0033] Furthermore, a limit sliding groove 19 with a radial direction and communicating with the limit groove 22 is also formed on the upper side of the limit seat 18. A sliding block 20 is slidably installed in the limit sliding groove 19. The lower end of the sliding block 20 is connected to the limit plate 23, and the upper end is connected with a dial block 21.

[0034] Before installing the movable distribution bin 10, the dial block 21 is pulled outwards to move the limit plate 23 outwards to create an installation space for the movable distribution bin 10. After the movable distribution bin 10 is installed in place, the dial block 21 is pushed inwards to move the limit plate 23 inwards to constrain the axial displacement of the movable distribution bin 10.

[0035] During use, the transmission rod 9 of the movable distribution bin 10 is aligned with the cross-shaped groove 5 on the connecting shaft 4, and the movable distribution bin 10 is installed in the first receiving groove 2. After the pulp enters the second receiving groove 11 through the feed pipe 25, the driving motor 7 is started to drive the movable distribution bin 10 to rotate. The distribution boss 12 provided with the inclined plate 13 evenly scatters the pulp. The evenly scattered pulp is conveyed into the first receiving groove 2 through the first discharge pipe 16. Since the movable distribution bin 10 is in a rotating state, the pulp can maintain an evenly scattered state by means of centrifugal force and is evenly distributed on the fine filter mesh plate 30 and the coarse filter mesh plate 31 of each filter tank. After being alternately filtered by the fine filter mesh plate 30 and the coarse filter mesh plate 31, the mineral particles are stratified according to size, so that an approximately equal amount of mineral particles uniformly penetrate into each filter tank, which can effectively prevent the uneven mixing of mineral contents in different filter tanks. The evenly distributed pulp is finally discharged through the second discharge pipe 33.

[0036] The standard parts used in the present invention can all be purchased from the market, and the special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part all adopt conventional means such as bolts, rivets, and welding that are mature in the prior art. The machines, parts, and equipment all adopt conventional models in the prior art. The circuit connection adopts the conventional connection method in the prior art, which will not be elaborated here. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
