Description

Technical Field

[0001] The present invention relates to the technical field of gate valve material processing, and in particular to a material processing mechanism and a processing method for a DSV discharge gate valve. Background Art

[0002] DSV in valves usually refers to "Downhole Safety Valve" or similar safety valve equipment. Its main function is to ensure the safe operation of the system under specific pressure conditions. The downhole gate valve is the downhole component in the DSV valve. The downhole gate valve is a device used to control the flow of solid materials and is commonly found in industrial material conveying systems. Its main function is to regulate the discharge of materials and ensure that it can be opened or closed quickly when needed to achieve the purpose of flow control. The gate valve can more accurately control the flow or delivery of powder, granular materials, granular materials and small pieces of materials. It is widely used in metallurgy, mining, building materials, electricity, food, chemical industry and other industries to control the rapid opening and closing of the medium. For example, the food industry: control the flow of food powder or particles to ensure the efficiency of the production line and the quality of the product. Mining and metallurgy: used to process ore, coal powder or other mineral materials to ensure the smooth production process.

[0003] The gate valves in the prior art all use power equipment to drive the gate plate to move horizontally to control the opening and closing of the gate valve. When in use, the power equipment is first used to drive the gate plate to move horizontally to block the material drop channel, then the material is piled on the gate plate, and finally the power equipment is used to pull the gate plate so that the gate plate is moved away from the position blocking the material drop channel, thereby opening the material drop channel, and the material piled on the gate plate falls into the material drop channel under the action of gravity;

[0004] However, when actually using the DSV discharge gate valve, it is necessary to consider preventing material accumulation and blockage, that is, mineral materials such as ore or food particles are large in volume and do not meet the emission standards and accumulate inside the gate valve, causing blockage or unsmooth discharge. Therefore, the material needs to be crushed in time inside the gate valve to solve the above problems, thereby improving the efficiency of the production line. At the same time, it is necessary to monitor the material flow and valve status in real time to optimize the operating effect and prevent failures. Therefore, the present invention solves the shortcomings of the above technical problems. Summary of the invention

[0005] Based on the above-mentioned existing technical problems, the present invention proposes a material handling mechanism and a material handling method of a DSV discharge gate valve.

[0006] The present invention proposes a material processing mechanism of a DSV discharge gate valve, comprising a processing pipe for crushing materials, the upper surface of the processing pipe is hinged with a discharge pipe in a bent shape, and the discharge pipe is fixedly connected to the processing pipe by fixing bolts, the lower surface of the processing pipe is fixedly connected with a discharge pipe, the inner surface of the processing pipe is provided with a crushing mechanism, the outer surface of the discharge pipe is provided with an opening and closing mechanism, and the interior of the discharge pipe is provided with a material shaking mechanism.

[0007] The material is discharged from the discharge pipe. When the material does not meet the discharge specifications and is blocked inside the processing pipe, the crushing mechanism is started and crushes the material so that it falls into the discharge pipe to complete the discharge.

[0008] The opening and closing mechanism controls the discharge flow of the discharge pipe so that the material meets the conveying speed.

[0009] When the material is discharged in the discharge pipe, the material shaking mechanism stirs the material inside it up and down, so that the material shaking mechanism increases the gap between the materials to enable rapid discharge of the materials, thereby avoiding blockage of the discharge pipe opening.

[0010] Preferably, the crushing mechanism comprises V-shaped guide plates symmetrically distributed and fixedly connected to the inner side wall of the upper end of the processing tube.

[0011] Through the above technical solution, the drop pipe is in a bent shape, so that the speed of the material falling into the drop pipe can be buffered. In order to guide the material to the surface of the crushing mechanism, a guide plate with an opening facing downward is provided at the connection between the drop pipe and the processing pipe, so that the material can be guided to the middle part of the processing pipe.

[0012] Preferably, the crushing mechanism further comprises two crushing rollers rotatably connected to the inner surface of the processing tube via bearings, the outer surfaces of the crushing rollers are fixedly connected with crushing blades distributed in a linear array, and two adjacent groups of crushing blades are staggered with each other.

[0013] Through the above technical scheme, in order to make the conveyed materials meet the needs, the materials are screened through two sets of crushing rollers and crushing blades, that is, the materials that do not meet the standards are stuck on the surfaces of the two sets of crushing blades. At this time, the materials can be crushed by the rotation of the crushing rollers, and then fall into the discharge pipe for discharge.

[0014] Preferably, the crushing mechanism also includes a transmission gear fixedly sleeved on the outer surface of one end of the two crushing rollers, the two transmission gears are meshed with each other, and the outer surface of the other end of one of the crushing rollers is fixedly connected to a reduction motor installed on the outer surface of the processing tube.

[0015] Through the above technical solution, in order to drive the two crushing rollers to drive their respective crushing blades to rotate, when the reduction motor drives one of the crushing rollers to rotate, the other crushing roller rotates synchronously and uniformly under the meshing of the two transmission gears, thereby achieving the crushing effect.

[0016] Preferably, the opening and closing mechanism includes a connecting tube fixedly connected to the lower surface of the feeding tube and having a smooth arc surface. The lower surface of the connecting tube is symmetrically distributed and slidably connected with a fan-shaped opening and closing plate that is covered on the outer surface of the feeding tube and the connecting tube. A material baffle plate is fixedly connected to the inner surface of one end of the opening and closing plate, and the two opening and closing plates move relative to or away from each other.

[0017] Through the above technical scheme, in order to control the flow of falling materials, the two opening and closing plates with the baffle plate can seal the lower surface of the connecting pipe when they are closed, and the inner surface of the opening and closing plate is an arc-shaped smooth surface that matches the path of the outer surface of the lower end of the connecting pipe. Therefore, when the two opening and closing plates move away from each other, the opening and closing plates slide in a path on the lower surface of the connecting pipe, and then the lower surface of the connecting pipe can be gradually opened, thereby realizing the control of the flow rate, and the baffle plate can prevent the material from jumping out from both sides of the connecting pipe.

[0018] Preferably, the opening and closing mechanism also includes a rotating shaft fixedly connected to the two end surfaces of the two opening and closing plates, one end of the rotating shaft is rotatably connected to the outer surface of the processing tube, the outer surfaces of the multiple rotating shafts are fixedly connected with linkage gears, and two adjacent linkage gears are meshed. The two side surfaces of one opening and closing plate are hingedly installed with a pushing cylinder, and the piston rod surface of the pushing cylinder is hinged to the surface at the corresponding position of the other opening and closing plate.

[0019] Through the above technical scheme, in order to realize the synchronous opening and closing action of the two opening and closing plates and accurately control the flow rate of the discharged material, the two pushing cylinders on both sides of an opening and closing plate are started at the same time, and the piston rods thereof push the other opening and closing plate to open on the lower surface of the connecting pipe, so that the opened opening and closing plate drives the rotating shaft, that is, the linkage gear on its outer surface to rotate, thereby causing the other linkage gear to rotate, and then drives the opening and closing plate hinged to the cylinder body of the pushing cylinder to open synchronously, at this time, the material can be discharged under the mutual friction between the inner surface of the opening and closing plate and the lower surface of the connecting pipe.

[0020] Preferably, the opening and closing mechanism further comprises a pressure sensor fixedly mounted inside the two opening and closing plates, and a limit rod is rotatably sleeved on the outer surface of the adjacent rotating shaft.

[0021] Through the above technical scheme, in order to ensure the opening and closing action of the opening and closing plate, it is necessary to monitor the bearing force of its inner surface in real time, so that the sealing of the opening and closing plate to the lower surface of the connecting pipe can be realized. Therefore, the material on its inner surface can be monitored by the pressure sensor. In order to maintain the meshing of adjacent linkage gears, the distribution position of the linkage gears is limited by the limit rod, so that it is convenient to push the cylinder to control the opening and closing of the opening and closing plate.

[0022] Preferably, the shaking material mechanism includes a mounting plate symmetrically distributed and fixedly connected to the inner wall of the discharge tube, the surface of the mounting plate is slidably connected with a movable rod with a limiting block through a sliding hole opened therethrough, the surfaces of the opposite sides of two adjacent movable rods on one side are fixedly connected with mounting rods distributed at intervals, the surfaces of the opposite sides of two groups of mounting rods are fixedly connected with shaking rods distributed at intervals, and the outer surfaces of the shaking rods are distributed in a linear array and rotatably sleeved with toggle gears.

[0023] Through the above technical scheme, the crushed materials are concentrated inside the discharge pipe and the connecting pipe before discharge. In order to make the material discharge process uniform and not get stuck inside the discharge pipe, the four movable rods are synchronously extended and slid up and down, driving the shaking rod connected by the mounting rod to move the materials between the shaking rods up and down. At this time, the shaking of the material causes the toggle gear to rotate relatively, so that the up and down shaking and rotation of the toggle gear can increase the gap between the materials, so that the material can be discharged at a uniform speed.

[0024] Preferably, the material shaking mechanism also includes a driving block hinged on the upper surface of the two movable rods on one side through a hinge block, and a linkage block is hinged on one side surface of the driving block. A pulley assembly housing and a driving motor are fixedly installed on one side surface of the discharge pipe, and the driving motor drives the two linkage blocks to eccentrically rotate through the pulley assembly inside the pulley assembly housing.

[0025] Through the above technical scheme, in order to drive the shaking rod and the toggle gear to move up and down to achieve the shaking of the material, the pulley assembly inside the pulley assembly housing is connected to the connecting shaft of the two linkage rods, and the pulley assembly includes a pulley and a transmission belt. Then the driving motor can drive the two linkage blocks to rotate synchronously, so that the free end of the pulley drives the hinged driving block to move up and down, thereby driving the movable rod to extend and retract up and down in the sliding hole to complete the shaking action.

[0026] The present invention provides a method for processing a material processing mechanism of a DSV discharge gate valve, comprising the following steps:

[0027] S1. The materials in the production line are buffered by the speed through the drop pipe and then flow through the guide plate and fall into the processing pipe. The materials that meet the discharge standards pass through the crushing mechanism of the processing pipe and fall into the drop pipe for collection, while the materials that do not meet the standards are stuck on the surfaces of the two sets of crushing blades;

[0028] S2. In order to make the material flow smoothly, the reduction motor drives one of the crushing rollers to rotate, and then the other crushing roller rotates synchronously and uniformly under the meshing of the two transmission gears, so that the two crushing rollers can drive their respective crushing blades to rotate, so that the material falls into the discharge pipe for collection after being crushed;

[0029] S3. When the pressure sensor detects that the material collected in the discharge pipe reaches the upper limit, the gate valve starts to discharge the material. The two push cylinders on both sides of an opening and closing plate are started at the same time, and the piston rods thereof push the other opening and closing plate to open on the lower surface of the connecting pipe, so that the opened opening and closing plate drives the rotating shaft, that is, the linkage gear on its outer surface to rotate, and then the other linkage gear rotates under the connection of the limit plate, and then drives the opening and closing plate hinged to the cylinder body of the push cylinder to open synchronously. At this time, the inner surface of the opening and closing plate and the lower surface of the connecting pipe can realize the discharge of the material under the mutual friction, and the opening and closing size of the two opening and closing plates can realize the control of the material flow rate;

[0030] S4. In order to make the material discharge process uniform and not get stuck inside the discharge pipe during the discharge process of the gate valve, the pulley assembly inside the pulley assembly housing is connected to the connecting shaft of the two linkage rods, and then the driving motor can drive the two linkage blocks to rotate synchronously, so that the free end of the linkage block drives the hinged drive block to move up and down, thereby driving the four movable rods on both sides to slide up and down synchronously, and the shaking rod also moves up and down, so that it moves the material between the shaking rods. At this time, the shaking of the material causes the toggle gear to rotate relatively, so that the up and down shaking and rotation of the toggle gear can increase the gap of the material, thereby making the material discharge at a uniform speed.

[0031] The beneficial effects of the present invention are:

[0032] 1. By setting up a crushing mechanism, the material stuck inside the gate valve can be crushed in time to make the material discharge smooth. During the adjustment process, one of the crushing rollers is driven to rotate by the reduction motor, and then the other crushing roller is rotated synchronously and uniformly under the engagement of two transmission gears. The two crushing rollers can drive their respective crushing blades to rotate, so that the material falls into the discharge pipe for collection after being crushed, thereby avoiding accumulation of materials that do not meet the emission standards inside the gate valve, causing blockage or unsmooth discharge.

[0033] 2. By setting up the opening and closing mechanism, the discharge flow of the material can be controlled so that the material meets the conveying speed. During the adjustment process, the two pushing cylinders on both sides of an opening and closing plate are started at the same time, and the piston rods thereof push the other opening and closing plate to open on the lower surface of the connecting pipe, so that the opened opening and closing plate drives the rotating shaft, that is, the linkage gear on its outer surface to rotate, and then the other linkage gear rotates under the connection of the limit plate, and then drives the opening and closing plate hinged with the pushing cylinder body to open synchronously. At this time, the inner surface of the opening and closing plate and the lower surface of the connecting pipe can realize the discharge of the material under the mutual friction, so that the crushed material can be discharged in time, so that the gate valve can operate continuously and improve the efficiency of the production line.

[0034] 3. By setting up a shaking mechanism, the crushed materials can be shaken to make the discharge smooth. During the adjustment process, the driving motor drives the two linkage blocks to perform synchronous rotation through the pulley assembly inside the pulley assembly housing, so that the free end of the pulley drives the hinged driving block to move up and down, thereby driving the four movable rods on both sides to synchronously extend and slide up and down. At this time, the shaking rod also moves up and down, so that it moves the materials between the shaking rods. At this time, the shaking of the material causes the shifting gear to rotate relatively, so that the up and down shaking and rotation of the shifting gear can increase the gap between the materials, thereby making the materials discharge at a uniform speed.

DETAILED DESCRIPTION

[0045] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0046] Reference Figure 1-Figure 9 A material processing mechanism of a DSV discharge gate valve includes a processing tube 1 for crushing materials, a bent discharge tube 2 is hinged on the upper surface of the processing tube 1, and the discharge tube 2 is fixedly connected to the processing tube 1 by fixing bolts, a discharge tube 3 is fixedly connected to the lower surface of the processing tube 1, a crushing mechanism 4 is arranged on the inner surface of the processing tube 1, an opening and closing mechanism 5 is arranged on the outer surface of the discharge tube 3, and a material shaking mechanism 6 is arranged inside the discharge tube 3.

[0047] The material is discharged from the discharge pipe 3. When the material does not meet the discharge specifications and is blocked inside the processing pipe 1, the crushing mechanism 4 starts and crushes the material so that it falls into the discharge pipe 3 to complete the discharge.

[0048] The drop pipe 2 is in a bent shape, so that the speed of the material falling into the drop pipe 2 can be buffered. In order to guide the material to the surface of the crushing mechanism 4, the crushing mechanism 4 includes a V-shaped guide plate 41 that is symmetrically distributed and fixedly connected to the inner wall of the upper end of the processing tube 1. The guide plate 41 with an opening facing downward is arranged at the connection between the drop pipe 2 and the processing tube 1, so that the material can be guided to the middle part of the processing tube 1.

[0049] In order to make the conveyed materials meet the requirements, the crushing mechanism 4 also includes two crushing rollers 42 rotatably connected to the inner surface of the processing tube 1 through bearings. The outer surfaces of the crushing rollers 42 are fixedly connected with crushing blades 45 distributed in a linear array. The two adjacent groups of crushing blades 45 are staggered with each other. The two groups of crushing rollers 42 and crushing blades 45 are used to screen the materials. That is, the materials that do not meet the standards are stuck on the surfaces of the two groups of crushing blades 45. At this time, the materials can be crushed by the rotation of the crushing rollers 42, and then fall into the discharge pipe 3 for discharge.

[0050] In order to drive the two crushing rollers 42 to drive their respective crushing blades 45 to rotate, the crushing mechanism 4 also includes a transmission gear 43 fixedly sleeved on the outer surface of one end of the two crushing rollers 42, and the two transmission gears 43 are meshed with each other. The outer surface of the other end of one of the crushing rollers 42 is fixedly connected to a reduction motor 44 installed on the outer surface of the processing tube 1. When the reduction motor 44 drives one of the crushing rollers 42 to rotate, the other crushing roller 42 rotates synchronously and at a uniform speed under the meshing of the two transmission gears 43, thereby achieving the crushing effect.

[0051] By setting up the crushing mechanism 4, the material stuck inside the gate valve can be crushed in time to make the material discharge smooth. During the adjustment process, one of the crushing rollers 42 is driven to rotate by the reduction motor 44, and then the other crushing roller 42 is made to rotate synchronously and uniformly under the engagement of the two transmission gears 43, so that the two crushing rollers 42 can drive their respective crushing blades 45 to rotate, so that the material falls into the discharge pipe 3 for collection after being crushed, thereby avoiding accumulation of materials that do not meet the discharge standards inside the gate valve to cause blockage or unsmooth discharge.

[0052] The opening and closing mechanism 5 controls the discharge flow of the material discharge pipe 3 so that the material meets the conveying speed.

[0053] In order to control the flow rate of falling materials, the opening and closing mechanism 5 includes a connecting pipe 51 which is fixedly connected to the lower surface of the feeding pipe 3 and has a smooth arc surface. The lower surface of the connecting pipe 51 is symmetrically distributed and slidably connected with a fan-shaped opening and closing plate 52 which is covered on the outer surface of the feeding pipe 3 and the connecting pipe 51. A baffle plate 53 is fixedly connected to the inner surface of one end of the opening and closing plate 52. The two opening and closing plates 52 move relative to or away from each other. When the two opening and closing plates 52 with the baffle plate 53 are closed, the lower surface of the connecting pipe 51 can be sealed. The inner surface of the opening and closing plate 52 is an arc-shaped smooth surface that matches the path of the outer surface of the lower end of the connecting pipe 51. When the two opening and closing plates 52 move away from each other, the opening and closing plates 52 slide along the path on the lower surface of the connecting pipe 51, and then the lower surface of the connecting pipe 51 can be gradually opened, thereby realizing the control of the flow rate. The baffle plate 53 can prevent the material from jumping out from both sides of the connecting pipe 51.

[0054] In order to realize the synchronous opening and closing action of the two opening and closing plates 52 so as to accurately control the flow rate of the discharged material, the opening and closing mechanism 5 also includes a rotating shaft 54 ​​fixedly connected to the two end surfaces of the two opening and closing plates 52, one end of the rotating shaft 54 ​​is rotatably connected to the outer surface of the processing tube 1, and the outer surfaces of the multiple rotating shafts 54 are fixedly connected with linkage gears 55, and two adjacent linkage gears 55 are meshed. The two side surfaces of an opening and closing plate 52 are hingedly installed with a pushing cylinder 56, and the piston rod surface of the pushing cylinder 56 is hinged to the surface of the corresponding position of the other opening and closing plate 52. The two pushing cylinders 56 on both sides of an opening and closing plate 52 are started at the same time, and their piston rods push the other opening and closing plate 52 to open on the lower surface of the connecting tube 51, so that the opened opening and closing plate 52 drives the rotating shaft 54, that is, the linkage gear 55 on its outer surface to rotate, thereby causing the other linkage gear 55 to rotate, and then drives the opening and closing plate 52 hinged with the cylinder body of the pushing cylinder 56 to open synchronously. At this time, the inner surface of the opening and closing plate 52 and the lower surface of the connecting tube 51 rub against each other to realize the discharge of materials.

[0055] In order to ensure the opening and closing action of the opening and closing plate 52, it is necessary to monitor the bearing force of its inner surface in real time, so that the opening and closing plate 52 can seal the lower surface of the connecting pipe 51. Therefore, the opening and closing mechanism 5 also includes a pressure sensor 57 fixedly installed inside the two opening and closing plates 52. The outer surfaces of the adjacent rotating shafts 54 are rotatably sleeved with a limit rod 58, and the material on the inner surface is monitored by the pressure sensor 57. In order to maintain the engagement of the adjacent linkage gears 55, the outer surfaces of the adjacent rotating shafts 54 are rotatably sleeved with a limit rod 58, and the distribution position of the linkage gear 55 is limited by the limit rod 58, so that it is convenient to push the cylinder 56 to control the opening and closing of the opening and closing plate 52.

[0056] By setting up the opening and closing mechanism 5, the discharge flow rate of the material can be controlled so that the material meets the conveying speed. During the adjustment process, two pushing cylinders 56 on both sides of an opening and closing plate 52 are started at the same time, and their piston rods push the other opening and closing plate 52 to open on the lower surface of the connecting pipe 51, so that the opened opening and closing plate 52 drives the rotating shaft 54, that is, the linkage gear 55 on its outer surface to rotate, and then under the connection of the limit plate, the other linkage gear 55 is rotated, and then the opening and closing plate 52 hinged to the cylinder body of the pushing cylinder 56 is driven to open synchronously. At this time, the inner surface of the opening and closing plate 52 and the lower surface of the connecting pipe 51 can be rubbed against each other to realize the discharge of the material, so that the crushed material can be discharged in time, so that the gate valve can operate continuously and the production line efficiency is improved.

[0057] When the material is discharged in the discharge pipe 3, the material shaking mechanism 6 stirs the material inside it up and down, so that the material shaking mechanism 6 increases the gap between the materials to enable rapid discharge of the materials, thereby avoiding blockage of the discharge pipe 3.

[0058] The crushed materials are concentrated and accumulated inside the discharge pipe 3 and the connecting pipe 51 before discharge. In order to make the material discharge process uniform and not get stuck inside the discharge pipe 3, the shaking mechanism 6 includes a mounting plate 61 symmetrically distributed and fixedly connected to the inner wall of the discharge pipe 3. The surface of the mounting plate 61 is slidably connected with a movable rod 62 with a limit block through a sliding hole opened therethrough. The opposite side surfaces of two adjacent movable rods 62 on one side are fixedly connected with mounting rods 63 distributed at intervals. The opposite side surfaces of the two groups of mounting rods 63 are fixedly connected with shaking rods 64 distributed at intervals. The outer surfaces of the shaking rods 64 are distributed in a linear array and rotatably sleeved with a toggle gear 65. The four movable rods 62 are synchronously telescopically slid up and down, driving the shaking rod 64 connected by the mounting rod 63 to toggle the materials between the shaking rods 64 up and down. At this time, the shaking of the materials causes the toggle gear 65 to rotate relatively, so that the up and down shaking and rotation of the toggle gear 65 can increase the gap between the materials, so that the materials can be discharged at a uniform speed.

[0059] In order to drive the shaking rod 64 and the toggle gear 65 to move up and down to achieve the shaking of the material, the shaking mechanism 6 also includes a driving block 66 hinged on the upper surface of the two movable rods 62 on one side through a hinge block, and a linkage block 67 is hinged on one side surface of the driving block 66. A pulley assembly housing 68 and a driving motor 69 are fixedly installed on one side surface of the discharge tube 3. The pulley assembly inside the pulley assembly housing 68 is transmission-connected to the connecting shafts of the two linkage blocks 67. The pulley assembly includes a pulley and a transmission belt. Then the driving motor 69 can drive the two linkage blocks 67 to rotate synchronously, so that the free end thereof drives the hinged driving block 66 to move up and down, thereby driving the movable rod 62 to extend and retract up and down in the sliding hole to complete the shaking action.

[0060] By setting up the shaking mechanism 6, the crushed material can be shaken to make the discharge smooth. During the adjustment process, the driving motor 69 drives the two linkage blocks 67 to perform synchronous rotation through the pulley assembly inside the pulley assembly housing 68, so that the free end of the drive block 66 drives the hinged drive block 66 to move up and down, thereby driving the four movable rods 62 on both sides to synchronously extend and slide up and down. At this time, the shaking rod 64 also moves up and down, so that it moves the material between the shaking rods 64. At this time, the shaking of the material causes the toggle gear 65 to rotate relatively, so that the up and down shaking and rotation of the toggle gear 65 can increase the gap between the materials, thereby making the materials discharged at a uniform speed.

[0061] Reference Figure 1-Figure 9 A method for processing a material processing mechanism of a DSV discharge gate valve comprises the following steps:

[0062] S1. The materials in the production line are buffered by the speed through the drop pipe 2 and then flow through the guide plate 41 and fall into the inside of the processing pipe 1. The materials that meet the discharge standards pass through the crushing mechanism 4 of the processing pipe 1 and fall into the discharge pipe 3 for collection, while the materials that do not meet the standards are stuck on the surfaces of the two sets of crushing blades 45.

[0063] S2. In order to make the material flow smoothly, the reduction motor 44 drives one of the crushing rollers 42 to rotate, and then the other crushing roller 42 is rotated synchronously and uniformly under the meshing of the two transmission gears 43, so that the two crushing rollers 42 can drive their respective crushing blades 45 to rotate, so that the material falls into the discharge pipe 3 for collection after being crushed;

[0064] S3. When the pressure sensor 57 detects that the material collected in the discharge pipe 3 reaches the upper limit, the gate valve starts to discharge the material, and the two push cylinders 56 on both sides of an opening and closing plate 52 are started at the same time, and the piston rods thereof push the other opening and closing plate 52 to open on the lower surface of the connecting pipe 51, so that the opened opening and closing plate 52 drives the rotating shaft 54, that is, the linkage gear 55 on its outer surface to rotate, and then the other linkage gear 55 is rotated under the connection of the limit plate, and then drives the opening and closing plate 52 hinged to the cylinder body of the push cylinder 56 to open synchronously, at this time, the inner surface of the opening and closing plate 52 and the lower surface of the connecting pipe 51 can realize the discharge of the material under the mutual friction, and the opening and closing size of the two opening and closing plates 52 can realize the control of the material flow rate;

[0065] S4. In order to make the material discharge process uniform and not get stuck inside the discharge pipe 3 during the discharge process of the gate valve, the driving motor 69 drives the two linkage blocks 67 to perform synchronous rotation through the pulley assembly inside the pulley assembly housing 68, so that the free end of the gate valve drives the hinged driving block 66 to move up and down, thereby driving the four movable rods 62 on both sides to synchronously extend and slide up and down. At this time, the shaking rod 64 also moves up and down, so that it moves the material between the shaking rods 64. At this time, the shaking of the material causes the toggle gear 65 to rotate relatively, so that the up and down shaking and rotation of the toggle gear 65 can increase the gap between the materials, thereby making the material discharge at a uniform speed.

6. A processing method for the material processing mechanism of the DSV discharge gate valve according to claim 5, comprising the following steps: S1, the materials in the production line are buffered by the speed through the drop pipe (2) and then flowed through the guide plate (41) into the inside of the processing pipe (1). The materials that meet the discharge standards pass through the crushing mechanism (4) of the processing pipe (1) and fall into the discharge pipe (3) for collection, while the materials that do not meet the standards are stuck on the surfaces of the two sets of crushing blades (45); S2. In order to make the material flow smoothly, the reduction motor (44) drives one of the crushing rollers (42) to rotate, and then the other crushing roller (42) is rotated synchronously and uniformly under the meshing of the two transmission gears (43). Then, the two crushing rollers (42) drive their respective crushing blades (45) to rotate, so that the material falls into the discharge pipe (3) for collection after being crushed; S3. When the pressure sensor (57) detects that the material collected in the discharge pipe (3) reaches the upper limit, the gate valve starts to discharge the material. The two push cylinders (56) on both sides of an opening and closing plate (52) are started simultaneously, and the piston rods thereof push the other opening and closing plate (52) to open on the lower surface of the connecting pipe (51), so that the opened opening and closing plate (52) drives the rotating shaft (54), that is, the linkage gear (55) on its outer surface to rotate, and then the other linkage gear (55) is rotated under the connection of the limit plate, and then drives the opening and closing plate (52) hinged to the cylinder body of the push cylinder (56) to open synchronously. At this time, the inner surface of the opening and closing plate (52) and the lower surface of the connecting pipe (51) rub against each other to realize the discharge of the material, and the opening and closing size of the two opening and closing plates (52) can realize the control of the material flow rate; S4. In order to ensure that the material is discharged at a uniform speed and does not get stuck inside the discharge pipe (3) during the discharge process of the gate valve, the driving motor (69) drives the two linkage blocks (67) to perform synchronous rotational motion through the pulley assembly inside the pulley assembly housing (68), so that the free end thereof drives the hinged driving block (66) to move up and down, thereby driving the four movable rods (62) on both sides to synchronously extend and slide up and down. At this time, the shaking rod (64) also moves up and down accordingly, so that it moves the material between the shaking rods (64). At this time, the shaking of the material causes the toggle gear (65) to rotate relatively, so that the up and down shaking and rotation of the toggle gear (65) can increase the gap between the materials, thereby making the material discharge at a uniform speed.
