Description

Technical Field

[0001] This utility model relates to the field of iron trough castable production technology, and in particular to an energy-saving and efficient crushing device for iron trough castable production. Background Technology

[0002] With the rapid development and continuous improvement of the metallurgical industry, various blast furnaces have adopted various technologies to continuously strengthen their metallurgical processes in order to increase output. During operation, refractory castables are not only subjected to direct scouring by high-temperature molten iron and slag, but also to mechanical wear, chemical corrosion, sudden temperature changes, or long-term operation at high temperatures, which causes refractory castables to be worn out.

[0003] Existing refractory trough castables require raw material crushing during preparation. For example, Chinese patent application CN202322274592.3 discloses a grinding device for trough castables, which specifically includes: an annular grinding wall inside the grinding chamber, with grinding rollers located inside the grinding wall, forming a grinding channel that is wider at the top and narrower at the bottom between the grinding rollers and the grinding wall. Raw materials are added to the crushing chamber inside the shell through a hopper and a feed pipe. A reduction motor is started, driving a rotating shaft to rotate. The rotation drives the crushing blades and grinding rollers to rotate through a first transmission mechanism and a second transmission mechanism. The rotating crushing blades crush the raw materials in the crushing chamber, and the grinding rollers in the grinding chamber grind the raw materials. This method has the following technical problems:

[0004] When grinding the raw materials of iron trough castable, large particles larger than the grinding channel cannot enter the grinding channel. When a large number of large particles are in the grinding chamber, they will block the grinding channel and thus affect the grinding efficiency. Utility Model Content

[0005] To address the problem mentioned in the background section that large particles of raw material cannot enter the grinding channel, this utility model provides the following technical solution:

[0006] An energy-saving and efficient crushing device for producing iron trough castable includes a crushing box;

[0007] The pulverizing chamber includes a chamber body, and a first grinding block is installed inside the chamber body.

[0008] The inside of the housing is equipped with a crushing structure for crushing raw materials in conjunction with the first grinding block, and the upper end of the housing is equipped with an electric push rod for controlling the up and down movement of the crushing structure.

[0009] The first grinding block has a grinding chamber in the middle, and a filter screen for screening the crushed raw materials is installed at the bottom of the grinding chamber. A guide component for controlling the up and down movement of the filter screen in conjunction with the crushing structure is installed at the lower end of the grinding chamber.

[0010] Furthermore, the upper end of the box is equipped with a feeding hopper for feeding raw materials into the inner cavity of the box, the bottom end of the box is equipped with a collection box for collecting the crushed raw materials, and the bottom of the box is provided with a rear door.

[0011] Furthermore, the interior of the box is equipped with a guide device for guiding the raw materials fed into the box, and a limiting ring for limiting the guide device is also installed inside the box.

[0012] Furthermore, a gear for controlling the rotation of the guide device is installed at the upper end of the inner cavity of the housing, and a motor for controlling the rotation of the gear is installed at one end of the gear.

[0013] Furthermore, a bottom tube is installed at the lower middle part of the filter screen, a slider is installed on the inner wall of the bottom tube, and a connecting ring is installed at the lower end of the filter screen.

[0014] Furthermore, a plurality of limiting rods are installed at the bottom of the grinding chamber. One end of each limiting rod is fitted with a bearing for limiting the guide assembly. A plurality of limiting rods are installed at the lower end of the first grinding block for limiting the connecting ring. The lower end of each limiting rod is fitted with a spring for controlling the upward movement of the connecting ring.

[0015] Furthermore, the lower outer wall of the guide assembly is provided with a wave groove for cooperating with the slider to control the vibration of the filter screen, and the inner wall of the guide assembly is equipped with helical blades.

[0016] Furthermore, the crushing structure includes a second grinding block for grinding the raw material in conjunction with the first grinding block. A control box for controlling the rotation of the second grinding block is installed at the upper end of the second grinding block, and a connecting rod is installed at the middle of the bottom end of the second grinding block. A slider is installed at the lower end of the connecting rod for cooperating with the spiral blade control guide assembly to rotate.

[0017] Furthermore, the guiding device includes a bottom ring, a top ring is installed at the upper end of the bottom ring, a toothed block is installed on one side of the bottom of the top ring for cooperating with gears to control the rotation of the top ring, and a plurality of guide vanes for guiding the raw materials are installed on the inner wall of the top ring.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] During the grinding of raw materials, the control box controls the second grinding block to grind the raw materials. During this process, the electric push rod controls the control box to move up and down, which in turn drives the connecting rod and slider two at the lower end of the second grinding block to move up and down. The upward movement of the second grinding block increases the gap between the second grinding block and the first grinding block, making it easier to grind large particles of raw materials. When the second grinding block moves up and down, slider two passes through the middle of the guide assembly. When slider two pushes the spiral blades, it causes the guide assembly to rotate, which causes slider one to move the filter screen downward under the guidance of the wave groove. At the same time, multiple springs push the filter screen upward, so that when the guide assembly rotates, the filter screen moves up and down and vibrates, which facilitates the crushed raw materials at the top of the filter screen to fall into the collection box for collection.

[0030] The preferred embodiments of this utility model are described in detail below, and a clear and complete explanation is given in conjunction with the accompanying drawings.

[0031] Please see Figures 1-6 This utility model provides an energy-saving and efficient crushing device for the production of iron trough castable, including a crushing box 100, which includes a box body 110. The upper end of the box body 110 is equipped with a feeding hopper 111 for feeding raw materials into the inner cavity of the box body 110. The bottom of the box body 110 is provided with a rear door 112. The bottom of the box body 110 is provided with a collection box 140 for collecting the crushed raw materials. With the rear door 112, the collection box 140 can be pulled out from the inside of the box body 110 after it is full. A first grinding block 113 is fixedly installed in the middle of the inner cavity of the box body 110, and a grinding chamber 114 is provided in the middle of the first grinding block 113.

[0032] The inside of the housing 110 is equipped with a crushing structure 200 for crushing raw materials in conjunction with the first grinding block 113. An electric push rod 120 is installed at the upper end of the housing 110 to control the crushing structure 200 to move up and down. When the electric push rod 120 controls the crushing structure 200 to move upward, it increases the gap between the crushing structure 200 and the grinding chamber 114, making it easier for large particles of raw materials to enter the grinding chamber 114 for crushing.

[0033] The bottom of the grinding chamber 114 is equipped with a filter screen 150 for screening the crushed raw materials. The filter screen 150 is designed so that the raw materials ground to the required size will fall into the collection box 140 through the middle hole of the filter screen 150 for collection. The raw materials that cannot pass through the middle hole of the filter screen 150 will continue to be crushed in the grinding chamber 114. The filter screen 150 is also set as a grinding block to facilitate the grinding of the raw materials at the top of the filter screen 150.

[0034] A base tube 151 is fixedly installed at the lower middle part of the filter screen 150. A slider 152 is fixedly installed on the inner wall of the lower end of the base tube 151. The slider 152 can be fixed to the inner wall of the base tube 151 by bolts. The bolts move from the outer wall of the base tube 151 to the inner wall of the base tube 151 and finally insert into a threaded hole on one side of the slider 152 to fix the slider 152 to the inner wall of the base tube 151. A connecting ring 153 is fixedly installed at the lower end of the filter screen 150.

[0035] The lower end of the grinding chamber 114 is equipped with a guide assembly 160 for cooperating with the crushing structure 200 to control the up and down movement of the filter screen 150. The lower outer wall of the guide assembly 160 is provided with a wave groove 161 for cooperating with the slider 152 to control the vibration of the filter screen 150. The slider 152 slides in the groove of the wave groove 161. The inner wall of the guide assembly 160 is fixedly installed with a spiral blade 162.

[0036] Multiple limiting rods 115 are fixedly installed at the bottom of the grinding chamber 114, and a vertical groove is opened in the middle of the connecting ring 153, through which the limiting rods 115 pass. A bearing 116 for limiting the guide assembly 160 is installed at one end of the limiting rod 115. The other end of the limiting rod 115 is fixedly installed on the outer wall of the outer ring of the bearing 116. The guide assembly 160 is sleeved in the middle of the inner ring of the bearing 116, so that the guide assembly 160 can rotate in the middle of the bearing 116.

[0037] Multiple limiting rods 117 are fixedly installed at the lower end of the first grinding block 113 to limit the connecting ring 153. By limiting the connecting ring 153 with multiple limiting rods 117, the filter screen 150 can move up and down within the grinding chamber 114. A spring 170 is sleeved on the lower end of the limiting rod 117 to control the upward movement of the connecting ring 153. The spring 170 always pushes the connecting ring 153 upward.

[0038] The crushing structure 200 includes a second grinding block 210 for grinding raw materials in conjunction with the first grinding block 113. A control box 211 for controlling the rotation of the second grinding block 210 is installed at the upper end of the second grinding block 210. A motor a for controlling the rotation of the second grinding block 210 is installed inside the control box 211. A connecting rod 212 is fixedly installed at the middle of the bottom end of the second grinding block 210. A slider 213 for cooperating with the spiral blade 162 to control the rotation of the guide assembly 160 is fixedly installed at the lower end of the connecting rod 212. The slider 213 is fixedly installed on the connecting rod 212 by bolts so that the slider 213 can be installed after the connecting rod 212 passes through the middle hole of the filter screen 150.

[0039] A guide device 300 for guiding raw materials fed into the box 110 is installed at the upper end of the inner cavity of the box 110. A limiting ring 118 for limiting the guide device 300 is fixedly installed at the upper end of the inner cavity of the box 110. A gear 130 for controlling the rotation of the guide device 300 is installed at the upper end of the inner cavity of the box 110. A motor 131 for controlling the rotation of the gear 130 is installed at one end of the gear 130.

[0040] The guiding device 300 includes a bottom ring 310, and a top ring 320 is mounted on the upper end of the bottom ring 310. The upper end of the top ring 320 is sloped to facilitate the movement of raw materials towards the center of the housing 110. Multiple bolts 322 for limiting the bottom ring 310 are mounted in the center of the top ring 320, and a cavity a is provided at the upper end of the top ring 320 for inserting the bolts 322. A rubber plug 323 is placed in the cavity a to prevent raw materials from falling into the cavity a. Multiple toothed blocks 321 are fixedly mounted on one side of the bottom of the top ring 320 to cooperate with the gear 130 to control the rotation of the top ring 320. Multiple guide vanes 324 for guiding the raw materials are fixedly mounted on the inner wall of the top ring 320.

[0041] When the raw material is fed into the housing 110 through the feed hopper 111, the raw material falls onto the top ring 320. When the motor 131 is started, the gear 130 and the gear block 321 control the top ring 320 to rotate, so that multiple guide vanes 324 disperse the raw material and prevent the raw material from piling up in one place when it falls.

[0042] During the grinding of raw materials, the control box 211 controls the second grinding block 210 to grind the raw materials. During this process, the electric push rod 120 controls the control box 211 to move up and down, which in turn drives the connecting rod 212 and the slider 213 at the lower end of the second grinding block 210 to move up and down. The upward movement of the second grinding block 210 increases the gap between the second grinding block 210 and the first grinding block 113, which facilitates the grinding of large particles. When the second grinding block 210 moves up and down, the slider 213 passes through the middle of the guide assembly 160. When the slider 213 pushes the spiral blade 162, it causes the guide assembly 160 to rotate. This causes the slider 152 to move the filter screen 150 downward under the guidance of the wave groove 161. At the same time, multiple springs 170 push the filter screen 150 upward. When the guide assembly 160 rotates, the filter screen 150 moves up and down and vibrates, which facilitates the crushed raw materials at the upper end of the filter screen 150 to fall into the collection box 140 for collection.

[0043] Based on the above description and accompanying drawings, those skilled in the art can understand and implement this utility model. Furthermore, any non-creative modifications made to this utility model by those skilled in the art without inventive effort are still within the protection scope of this utility model.
