Description

Technical Field

[0001] This utility model relates to the technical field of roller press devices, and in particular to a dust collection device for roller presses. Background Technology

[0002] Roller presses are widely used grinding equipment, mainly used in industries such as cement, mining, and metallurgy. Their main function is to compress materials into dense cakes through two opposing and synchronously rotating extrusion rollers, thereby improving the grindability of materials and increasing grinding efficiency. However, roller presses generate dust when extruding materials, which can affect the working environment around the press.

[0003] Especially in cement production, when the feeding belt carries materials such as clinker, volcanic ash, and gypsum into the roller press through the feed inlet, the extrusion rollers will squeeze the material. Due to the friction and collision between particles, dust will be generated, and this dust will escape along the feed inlet to the outer periphery of the roller press, affecting the working environment of the workers.

[0004] Based on the above situation, it is necessary to design a dust collection device for a roller press to solve the above problems. Utility Model Content

[0005] This invention provides a dust collection device for a roller press, which solves the problem in the prior art that dust generated during the operation of a roller press will escape along the feed inlet to the outer periphery of the roller press.

[0006] The technical problem solved by this utility model is achieved by the following technical solution:

[0007] A dust collection device for a roller press includes a roller press body and a feed inlet located on the roller press body. It further includes: two guide plates hinged to the feed inlet and symmetrically arranged, with a discharge channel formed between the free edges of the two guide plates; a drive assembly that drives the two guide plates to rotate, thereby changing the width of the discharge channel; and a dust collection box connected to the feed inlet, located on one side of the guide plates near the interior of the roller press body, with a negative pressure assembly on the roller press body for providing negative pressure to the dust collection box.

[0008] Preferably, the drive assembly includes a rotating shaft connected to the hinged edge of the guide plate, a dual-axis motor connected to the feed inlet, and a transmission component for transmitting the torsional force output by the dual-axis motor to the rotating shaft.

[0009] Preferably, the transmission component includes a worm gear connected to the rotating shaft, a worm screwed into the worm gear, and a transmission shaft connected to one end of the worm. The end of the transmission shaft away from the worm is connected to the output end of the dual-axis motor.

[0010] Preferably, the negative pressure assembly includes an air guide pipe I connected to the output end of the dust collection box, an air guide pipe II connected to the output end of the air guide pipe I, a dust filter box connected to the feed inlet, and an air pump installed on the feed inlet. The output end of the air guide pipe II is connected to the interior of the dust filter box, and the input end of the air pump is connected to the interior of the dust filter box through an air guide pipe III.

[0011] Preferably, the dust filter box is movably connected to several mesh frames, and filter screens are connected to the mesh frames.

[0012] Preferably, a suspension plate is fitted with a gap on the side of the guide plate near the unloading channel.

[0013] The beneficial effects of this utility model are as follows: By installing two guide plates at the feed inlet of the main body of the roller press, the width of the feeding channel can be adjusted by the drive component. This ensures that the material passing area at the feed inlet is reduced without affecting the feeding of the main body of the roller press, thus making it difficult for dust to escape from the feed inlet to the outside of the main body of the roller press. Under the action of the air pump, the dust near the feed inlet is sucked into the dust collection box, and the purified air is discharged under the action of the filter screen. In this process, the device structure will collect the dust generated by the operation of the extrusion roller body into a specific location, preventing the dust from escaping along the feed inlet to the outer periphery of the roller press and thus affecting the working environment of the workers.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0025] Reference Figures 1-8 As shown, a dust collection device for a roller press includes a roller press body 1 and a feed inlet 2 located on the roller press body 1. It also includes two guide plates 3 hinged to the feed inlet 2 and symmetrically arranged, a drive assembly 5, and a dust collection box 6 connected to the feed inlet 2. Specifically, a discharge channel 4 is formed between the free edges of the two guide plates 3. When the material falls onto the guide plates 3, because the guide plates 3 are inclined, the material will slide off the guide plates 3 and fall into the roller press body 1 from the discharge channel 4. The drive assembly 5 drives the two guide plates 3 to rotate in opposite directions. Under the action of the drive assembly 5, the free edges of the two guide plates 3 will rotate in opposite directions, thereby changing the width of the discharge channel 4. The dust collection box 6 is located on one side of the guide plates 3 near the inside of the roller press body 1. The dust collection box 6 is provided with several ventilation holes 60, and the roller press body 1 is provided with a negative pressure assembly for providing negative pressure to the dust collection box 6.

[0026] When the device is in use, as the main body 1 of the roller press starts moving and the feeding belt (not shown in the figure) feeds the material into the interior of the main body 1 of the roller press from the feed inlet 2, the drive component 5 is activated according to the material output of the feeding belt to adjust the width of the discharge channel 4 to accommodate the falling material. After falling from the feeding belt, the material will fall into the main body 1 of the roller press from the discharge channel 4 under the action of the guide plate 3. Because the position between the two extrusion rollers 20 is directly below the discharge channel 4, the material will form a cake under the extrusion action of the two extrusion rollers 20. During this process, the dust generated will move towards the feed inlet 2 with the airflow. Because the feeding channel 4 is narrowed and can only be used for material falling, dust will be blocked by the material at the feed inlet 2. Under the airflow carried by the material, the dust is not easy to escape from the feed inlet 2 to the outside of the roller press body 1. Therefore, the dust will continuously accumulate at the lower part of the guide plate 3. At the same time, the negative pressure component moves synchronously, and a negative pressure is formed in the dust collection box 6. Then, the dust accumulated near the feed inlet 2 is sucked into the dust collection box 6 through the vent 60. This collects the dust generated by the operation of the extrusion roller 20 into a specific location, preventing the dust from escaping along the feed inlet 2 to the outside of the roller press and affecting the working environment of the workers.

[0027] The drive assembly 5 includes a rotating shaft 7 connected to the hinged edge of the guide plate 3, a dual-axis motor 8 connected to the feed inlet 2, and a transmission component for transmitting the torsional force output by the dual-axis motor 8 to the rotating shaft 7. The guide plate 3 is connected to the feed inlet 2 through the rotating shaft 7. When the guide plate 3 rotates, its rotation trajectory is a circular motion with the axis of the rotating shaft 7 as the center. When the dual-axis motor 8 outputs, the torsional forces output by its two output ends are in opposite directions, thereby enabling the guide plate 3 to move towards or away from each other.

[0028] Next, the transmission components include a worm gear 9 connected to the rotating shaft 7, a worm 10 engaged with the worm gear 9, and a transmission shaft 11 connected to one end of the worm 10. The end of the transmission shaft 11 away from the worm 10 is connected to the output end of the dual-axis motor 8. When one output end of the dual-axis motor 8 is connected to the transmission components, the output end of the dual-axis motor 8 will drive the worm 10 connected to it to rotate through the transmission shaft 11, thereby driving the worm gear 9 engaged with the worm 10 to rotate. The worm gear 9 can then drive the rotating shaft 7 connected to the guide plate 3 to rotate, thereby driving the guide plate 3 connected to the rotating shaft 7 to rotate. At the same time, the other output end of the dual-axis motor 8 will also apply a torsional force to the transmission components connected to it, thereby driving the other guide plate 3 to rotate. The rotation directions of the two guide plates 3 are opposite or opposite to each other, so as to ensure that the feeding channel 4 is exactly above the position between the two extrusion rollers 20, so that the material is conveyed to the two extrusion rollers 20 in the correct direction.

[0029] Furthermore, the negative pressure assembly includes an air guide pipe 12 connected to the output end of the dust collection box 6, an air guide pipe 2 13 connected to the output end of the air guide pipe 12, a dust filter box 14 connected to the feed inlet 2, and an air pump 15 installed on the feed inlet 2. The output end of the air guide pipe 2 13 is connected to the inside of the dust filter box 14, and the input end of the air pump 15 is connected to the inside of the dust filter box 14 through an air guide pipe 3 16.

[0030] Furthermore, in order to ensure that the dust content of the air output from the dust filter box 14 is within a standard range, several mesh frames 17 are movably attached to the dust filter box 14. Filter screens 18 are connected to the mesh frames 17. In use, the filter screens 18 are installed on the mesh frames 17, and then the mesh frames 17 are snapped onto the dust filter box 14. Under the action of the air pump 15, when the air guide pipe 2 13 introduces dust-containing air into the dust filter box 14, the dust in the flowing air is adsorbed onto the filter screens 18, thus ensuring that the air output from the air guide pipe 3 16 is clean air. During this process, if the filter screen 18's efficiency is affected by adsorbed dust, the mesh frame 17 can be removed from the dust filter box 14, and the filter screen 18 can be cleaned.

[0031] Furthermore, in order to facilitate the accumulation of dust below the guide plate 3, and also to reduce the impact of the airflow carried by the falling material on the already accumulated dust, a hanging plate 19 is fitted on the side of the guide plate 3 near the discharge channel 4. The hanging plate 19 extends the distance of the discharge channel 4. Under its own weight, the hanging plate 19 will deflect as the free side of the guide plate 3 moves, so that the hanging plate 19 is always perpendicular to the ground, thereby facilitating the collection of dust below the guide plate 3.
