Description

Technical Field

[0001] This utility model relates to the field of magnesium hydroxide processing technology, and in particular to an auxiliary discharge device for magnesium hydroxide production. Background Technology

[0002] The fine particle size of magnesium hydroxide ore after crushing makes its surface prone to static electricity due to friction, and it easily absorbs moisture in high-humidity environments, increasing its viscosity and causing it to adhere easily to the inner wall of the discharge pipe. Current technologies often address this blockage problem by installing a vibrating motor on the outer wall of the discharge pipe, using vibration to dislodge the adhered material. For severe blockages, manual tapping of the pipe by operators is required to clear the blockage. Some devices use fixed scrapers inside the discharge pipe, but the fixed gap between the scraper and the pipe wall makes it difficult to adapt to material layers of varying thicknesses, and long-term wear can reduce scraping effectiveness.

[0003] However, the above methods have significant shortcomings: the vibration energy of the vibratory motor gradually attenuates when transmitted in a rigid pipe. For pipe bends or areas far from the vibration source, the vibration intensity is insufficient and cannot effectively remove the attached material, leading to frequent local blockages. Manual tapping is not only labor-intensive and inefficient, but also difficult to control the tapping force, which can easily cause pipe deformation or loosening of connections, thus increasing the risk of material leakage. Fixed scrapers cannot dynamically adjust their fit with the inner wall of the pipe, making it difficult to completely remove hardened attached materials. As production time accumulates, the material layer gradually thickens, eventually leading to a narrow or even complete blockage of the discharge channel. This necessitates stopping the machine to disassemble the pipe for cleaning, severely interrupting the production process, significantly reducing production efficiency, and making it difficult to meet the needs of continuous production. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to propose an auxiliary discharge device for magnesium hydroxide production. The device uses a first driving device to drive the assembly side plate and the discharge vibration component to realize the opening and closing and vibration of the discharge screen, thereby promoting the discharge of materials. A dredging component is set up, and the dredging rod is driven by a second driving device to dredge the inside of the discharge screen with the assistance of a guide plate. This solves the problem that magnesium hydroxide material is prone to adhesion and blockage due to its fine particle size and the influence of static electricity and humidity.

[0006] To achieve the above objectives, this utility model proposes an auxiliary discharge device for magnesium hydroxide production, comprising an assembly base, supporting legs, a fixed sleeve, a crushing chamber, and an auxiliary discharge mechanism. One end of a plurality of supporting legs is fixedly connected in a circumferential array to the top of the assembly base. The fixed sleeve is fixedly connected to the other end of the plurality of supporting legs. The crushing chamber is fixedly connected to the inner wall of the fixed sleeve. The auxiliary discharge mechanism includes a supporting side plate, a first driving device, an assembly side plate, and a discharge vibration assembly.

The first driving device is installed on the outer wall of the supporting side plate, and its output end penetrates through the supporting side plate and is fixedly connected to one side of the assembly side plate. The discharge vibration assembly is installed on the other side of the assembly side plate. A discharge mesh is fixedly connected to the discharge port of the crushing chamber, and two discharge vibration assemblies are symmetrically fixedly connected to the surface of the discharge mesh.

[0007] This utility model discloses an auxiliary discharge device for magnesium hydroxide production. The first drive device of the auxiliary discharge mechanism drives the assembly side plate and the discharge vibration component to control the opening and closing of the discharge mesh sleeve. The vibration motor transmits vibration through the clamping plate to prevent material adhesion. The second drive device of the unblocking component drives the unblocking rod into the mesh sleeve to unblock the blockage. The material falls into the collection tank through the guide plate. This device prevents dust from overflowing through the airtight mesh sleeve, sealed connection and elastic steel ring. The combination of vibration and unblocking prevents blockage and solves the problems of easy material adhesion and blockage, poor discharge and dust pollution in the prior art.

[0008] In addition, the magnesium hydroxide production auxiliary discharge device proposed above according to this utility model may also have the following additional technical features:

[0009] Specifically, the discharge vibration assembly includes support springs, clamping plates, and a vibration motor. One end of each of the two support springs is symmetrically fixedly connected to the other side of the assembly side plate. One side of the clamping plate is fixedly connected to the other end of the support springs. The vibration motor is mounted on one side of the clamping plate, and the other side of the clamping plate is fixedly connected to the surface of the discharge mesh sleeve.

[0010] Specifically, it also includes a dredging assembly, which includes a protective housing, a second drive device, a dredging rod, support arms, and a guide plate. The protective housing is fixedly connected to the inner bottom of the assembly base. The second drive device is installed inside the protective housing. One end of the dredging rod passes through the protective housing and is fixedly connected to the output end of the second drive device. One end of a plurality of support arms is fixedly connected to the top of the assembly base in a circumferential array. The guide plate is sleeved on the outer wall of the dredging rod, and the outer wall of the guide plate is fixedly connected to the other end of the support arm.

[0011] Specifically, the top of the mounting base is provided with a collection groove, and the protective shell is installed on the inner bottom of the collection groove.

[0012] Specifically, the guide plate has a conical structure, and a sealing strip is installed at the junction of the top of the guide plate and the unblocking rod.

[0023] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. Rather, the embodiments of this utility model include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0024] The auxiliary discharge device for magnesium hydroxide production according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0025] like Figures 1-4 As shown, the auxiliary discharge device for magnesium hydroxide production in this embodiment of the present invention may include an assembly base 1, a support foot 2, a fixing sleeve 3, a crushing chamber 4, and an auxiliary discharge mechanism 5.

[0026] Among them, one end of multiple support feet 2 is fixedly connected to the top of the assembly base 1 in a circumferential array, the fixing sleeve 3 is fixedly connected to the other end of multiple support feet 2, and the crushing chamber 4 is fixedly connected to the inner wall of the fixing sleeve 3.

[0027] It should be noted that, in this embodiment, one end of the multiple support legs 2 is fixedly connected to the annular reinforcing boss on the top of the assembly base 1 in a circumferential array by welding. The reinforcing boss and the assembly base 1 are integrally formed to improve the support strength. The support legs 2 are made of hollow round steel, and triangular reinforcing ribs are evenly distributed on their outer walls. The two ends of the ribs are welded and fixed to the assembly base 1 and the support legs 2 respectively, which enhances the resistance of the support legs 2 to deformation when bearing the weight of the crushing chamber 4 and the working vibration. The fixing sleeve 3 is fixedly connected to the other end of the multiple support legs 2 by a high-strength bolt assembly. The inner wall of the fixing sleeve 3 is provided with an annular positioning groove, and the corresponding position of the outer wall of the crushing chamber 4 is provided with a matching annular flange. After the flange is embedded in the positioning groove, it is fixedly connected to the fixing sleeve 3 by circumferentially evenly distributed fastening bolts. A high-temperature resistant sealing gasket is installed between the flange and the positioning groove to prevent dust generated during the crushing process from escaping from the connection. At the same time, an elastic buffer pad is provided at the connection between the fixing sleeve 3 and the support legs 2, which can absorb the vibration generated when the crushing chamber 4 is working and avoid the vibration from being transmitted to the assembly base 1, causing the entire equipment to resonate.

[0028] The auxiliary discharge mechanism 5 includes a support side plate 51, a first drive device 52, an assembly side plate 53, and a discharge vibration assembly 54.

[0029] Among them, the support side plate 51 is symmetrically fixedly connected to the bottom of the fixed sleeve plate 3, the first drive device 52 is installed on the outer wall of the support side plate 51, the output end of the first drive device 52 passes through the support side plate 51 and is fixedly connected to one side of the assembly side plate 53, and the discharge vibration assembly 54 is installed on the other side of the assembly side plate 53.

[0030] It should be noted that the support side plate 51 described in this embodiment is made of high-strength alloy steel plate and is symmetrically connected to the preset mounting surface at the bottom of the fixed sleeve plate 3 by welding and bolting. A reinforcing angle plate is provided between the mounting surface and the support side plate 51. The angle plate is welded to the fixed sleeve plate 3 and the support side plate 51 respectively to improve the torque resistance of the support structure. The first driving device 52 is a double-acting cylinder. Its cylinder body is fixed to the outer wall of the support side plate 51 by a flange. A shock-absorbing rubber pad is added at the flange connection to reduce the vibration transmission during cylinder operation. The piston rod at the output end of the first driving device 52 passes through the support side plate. After the precision guide hole on plate 51, it is rigidly connected to one side of the assembly side plate 53 through a combination structure of shaft shoulder and locking nut. A self-lubricating copper sleeve is embedded in the guide hole to reduce frictional loss during the reciprocating motion of the piston rod. The assembly side plate 53 adopts a hollow frame structure, which reduces weight while ensuring structural strength. Its other side is precisely connected to the discharge vibration component 54 through a positioning pin and is fastened by circumferentially distributed bolts to ensure the stability of the vibration component during operation. At the same time, a long strip-shaped protective baffle is set on the support side plate 51 corresponding to the movement trajectory of the assembly side plate 53 to prevent material from splashing to the connection part of the drive device and causing contamination or jamming.

[0031] A discharge screen 41 is fixedly connected to the discharge port of the crushing chamber 4, and two discharge vibration components 54 are symmetrically fixedly connected to the surface of the discharge screen 41.

[0032] It should be noted that, in this embodiment, the discharge port of the crushing chamber 4 is fixedly connected to the top of the discharge mesh sleeve 41 via an annular clamp. A wear-resistant silicone gasket is provided inside the clamp to enhance the sealing of the connection and prevent damage to the mesh sleeve from rigid contact. The discharge mesh sleeve 41 is made of high-elasticity neoprene rubber, integrally vulcanized, with a smooth, mesh-free surface, forming a completely airtight, flexible discharge channel. Its wall thickness is uniform and has good elasticity, adapting to different discharge pressures and receiving heights, ensuring smooth passage of magnesium hydroxide material. Its outer wall... The two discharge vibration components 54 are integrally formed with reinforcing flanges. The surfaces of the reinforcing flanges are fixed with metal connecting seats by bolts. The clamping plates 542 of the two discharge vibration components 54 are rigidly connected to the metal connecting seats by bolts, and buffer rubber pads are added to the connection parts to make the vibration energy more efficiently transmitted to the whole mesh sleeve, avoiding the material from adhering and accumulating on the inner wall of the mesh sleeve. At the same time, the bottom edge of the discharge mesh sleeve 41 is wrapped with an elastic steel ring. The steel ring can adaptively fit according to the diameter of the receiving equipment, and form a closed discharge channel with the airtight structure to completely prevent dust from overflowing.

[0033] Specifically, based on the assembly base 1, the support foot 2 provides stable support for the fixed sleeve plate 3 through the annular reinforcing boss and reinforcing ribs. The fixed sleeve plate 3 fixes the crushing chamber 4 through the positioning groove and the flange. The support side plate 51 of the auxiliary discharge mechanism 5 carries the first driving device 52. The first driving device 52 drives the assembly side plate 53 and the discharge vibration component 54 to move, so that the discharge mesh sleeve 41 held by the discharge vibration component 54 can open and close. The vibration component transmits the vibration to the mesh sleeve through the reinforcing flange, which promotes the smooth discharge of magnesium hydroxide material. The device forms a closed channel through the airtight discharge mesh sleeve 41 made of high elastic neoprene rubber material. With the sealing connection of the annular clamp and the silicone gasket, and the fit design of the elastic steel ring at the bottom, dust is prevented from overflowing. At the same time, the vibration of the discharge vibration component 54 is used to avoid material adhesion and blockage. This solves the problems of blockage, poor discharge, and dust pollution caused by magnesium hydroxide due to its fine particle size and the influence of static electricity and humidity on the inner wall of the discharge pipe.

[0034] In one embodiment of this utility model, such as Figures 1-4 As shown, the discharge vibration assembly 54 includes a support spring 541, a clamping plate 542, and a vibration motor 543. One end of each of the two support springs 541 is symmetrically fixedly connected to the other side of the assembly side plate 53. One side of the clamping plate 542 is fixedly connected to the other end of the support spring 541. The vibration motor 543 is installed on one side of the clamping plate 542, and the other side of the clamping plate 542 is fixedly connected to the surface of the discharge mesh sleeve 41.

[0035] It should be noted that, as described in this embodiment, the two support springs 541 are made of high-strength alloy spring steel. One end of each spring is symmetrically fixed to a pre-set boss on the other side of the assembly side plate 53 by welding. The spring surface is coated with an anti-corrosion coating to cope with humid environments. The other end of the support spring 541 is fixed to the connecting ear plate on one side of the clamping plate 542 by a threaded connection, and an anti-loosening nut is added at the connection to ensure a stable connection. The clamping plate 542 adopts an arc-shaped structure design, the curvature of which matches the curvature of the outer wall of the discharge mesh sleeve 41. A 3-5mm thick oil-resistant rubber pad is pasted on the side of the clamping plate 542 that contacts the discharge mesh sleeve 41, and the surface of the pad has a diamond-shaped anti-slip texture, which enhances the clamping friction. To avoid causing hard damage to the mesh sleeve, the other side of the clamping plate 542 is rigidly connected to the mounting base of the vibrating motor 543 via a bolt assembly. An elastic damping pad is provided between the mounting base and the clamping plate 542 to reduce the noise transmission of the vibrating motor 543 during operation. The vibrating motor 543 is a frequency-adjustable micro vibrating motor with a frequency range of 20-50Hz. An eccentric block is installed on its output shaft, and the vibration amplitude can be changed by adjusting the phase angle of the eccentric block. When the vibrating motor 543 is working, the vibration is transmitted elastically through the clamping plate 542 and the support spring 541, causing the discharge mesh sleeve 41 to generate high-frequency micro-amplitude vibration, effectively preventing magnesium hydroxide material from adhering and accumulating on the inner wall of the mesh sleeve, and ensuring smooth discharge.

[0036] In one embodiment of this utility model, such as Figures 1-4 As shown, it also includes a dredging component 6, which includes a protective housing 61, a second drive device 62, a dredging rod 63, a support arm 64, and a guide plate 65. The protective housing 61 is fixedly connected to the inner bottom of the assembly base 1. The second drive device 62 is installed inside the protective housing 61. One end of the dredging rod 63 passes through the protective housing 61 and is fixedly connected to the output end of the second drive device 62. One end of multiple support arms 64 is fixedly connected to the top of the assembly base 1 in a circumferential array. The guide plate 65 is sleeved on the outer wall of the dredging rod 63, and the outer wall of the guide plate 65 is fixedly connected to the other end of the support arm 64.

[0037] Furthermore, the top of the mounting base 1 is provided with a collection groove 11, the protective shell 61 is installed on the inner bottom of the collection groove 11, the guide plate 65 is a conical structure, and a sealing strip is installed at the junction of the top of the guide plate 65 and the unblocking rod 63.

[0038] It should be noted that when the unblocking component 6 described in this embodiment is working, if material blockage occurs in the discharge mesh sleeve 41, the second drive device 62 inside the protective housing 61 is activated. The servo electric cylinder outputs power and transmits it to the unblocking rod 63 through the coupling, causing the unblocking rod 63 to move upward along the trajectory of the guide sleeve at the top of the protective housing 61. Its top end passes through the center of the guide plate 65 and enters the discharge mesh sleeve 41. The spiral guide ribs on the outer wall push and disperse the blocked magnesium hydroxide material to achieve unblocking. After unblocking is completed, the second drive... The actuator 62 drives the unblocking rod 63 to retract in the opposite direction, returning to the initial position below the guide plate 65. During this period, the lip-shaped sealing strip on the inner wall of the guide plate 65 always adheres to the surface of the unblocking rod 63 to prevent material from entering the protective shell 61. The qualified magnesium hydroxide material discharged from the discharge net sleeve 41 falls onto the surface of the conical guide plate 65 under the action of gravity. Because the guide plate 65 is coated with a polytetrafluoroethylene anti-stick coating, the material slides along the 30° conical surface into the collection trough 11 at the top of the assembly base 1. The 5° inclined structure at the bottom of the trough assists the material to accumulate in the trough, completing the collection.

[0039] In summary, the magnesium hydroxide production auxiliary discharge device of this utility model embodiment has a first driving device 52 of the auxiliary discharge mechanism 5 driving the assembly side plate 53 and the discharge vibration component 54 to control the opening and closing of the discharge mesh sleeve 41. The vibration motor 543 transmits vibration through the clamping plate 542 to prevent material adhesion. The second driving device 62 of the unblocking component 6 drives the unblocking rod 63 into the mesh sleeve to unblock the blockage. The material falls into the collection tank 11 through the guide plate 65. This device solves the problems of easy material adhesion and blockage, poor discharge and dust pollution in the background art by using an airtight mesh sleeve, sealed connection and elastic steel ring to prevent dust from overflowing. The combination of vibration and unblocking prevents blockage.
