Abstract
Description
Technical Field
[0001] This utility model relates to the field of conveying device technology, and more specifically, to a refractory castable conveying device. Background Technology
[0002] In the operation and maintenance of high-temperature equipment in industries such as metallurgy, building materials, and chemicals, refractory castables are key lining materials. Their conveying efficiency and quality directly affect the equipment maintenance cycle and operational stability. Currently, the industry commonly uses screw conveyors, pneumatic conveying systems, or belt conveyors for pipeline transportation of refractory castables. However, in practical applications, it has been found that traditional conveying devices have two major technical defects: the difficulty in cleaning residual material adhering to the pipe wall and the severe wear of the pipe wall by the castable during the transportation process. These defects restrict the operating efficiency of the equipment.
[0003] On the one hand, refractory castables have a high content of fine powder and significant differences in fluidity. Fine powder is easily adsorbed onto the inner wall of the pipe, causing a dense adhesion layer to gradually form on the pipe wall. This residual layer not only continues to thicken, causing an increase in conveying resistance, but also forms a structural blockage due to the hardening of the material after shutdown. Existing cleaning processes require disassembling the pipe for mechanical scraping, which is cumbersome and easily causes dust diffusion, affecting the working environment and significantly extending the equipment restart cycle.
[0004] On the other hand, refractory castables generally contain hard aggregates such as corundum and silicon carbide, whose Mohs hardness is generally above 8.0, which causes continuous frictional wear on the pipe wall during high-speed transportation.
[0005] Therefore, existing conveying devices are inadequate in dealing with residual material cleaning and pipe wall wear. Utility Model Content

[0012] A first transmission wheel is fixedly connected to one side of the first baffle, and a second transmission wheel is fixedly connected to one side of the second baffle. Both the first and second transmission wheels are provided with transmission cams.

The transmission component drives the first baffle and the second baffle to rotate through two sets of transmission cams, sealing the top of the conveying pipeline. At this time, the fan blows out the residual material in the conveying pipeline, improving the efficiency of the user in cleaning the conveying pipeline. Second, before the refractory castable is conveyed to the conveying pipeline, larger pieces of material are screened out in the screening bucket through the screen plate. At the same time, the second motor drives the crushing blades through the transmission shaft to crush the larger pieces of material, which can prevent the larger pieces of material from rubbing against the conveying pipeline and causing excessive wear of the conveying pipeline. An inner lining tube is installed in the conveying pipeline, so that the inner lining tube rubs against the refractory castable. After the inner lining tube is worn, a new inner lining tube can be quickly removed and installed, which is lower in cost than the overall replacement cost when the conveying pipeline is worn.

[0028] A spiral push rod 107 is provided at one end of the first motor 102, an inner liner 108 is provided inside the conveying pipe 100, a first baffle 109 and a second baffle 110 are provided inside the conveying pipe 100, a mounting base 111 is provided on one side of the conveying pipe 100, a cylinder 112 and a transmission component 113 are provided inside the mounting base 111, and a fan 114 is provided on one side of the conveying pipe 100.
[0029] A first flange 115 is provided at one end of the conveying pipe 100. A sealing cover 116 is bolted to one end of the first flange 115. The flange connection ensures the sealing of the conveying pipe 100 and prevents leakage of refractory castable during transportation. A first connection hole is opened at one end of the sealing cover 116. The main shaft of the first motor 102 passes through the first connection hole. A spiral push rod 107 is detachably connected to one end of the first motor 102. The refractory castable enters the conveying pipe 100 from the bottom of the screening bucket 101. The spiral push rod 107 driven by the first motor 102 conveys the refractory castable.
[0030] A second flange 117 is welded to the top of the conveying pipe 100. A screening bucket 101 is fixedly connected to the top of the second flange 117. A bucket cover 118 is bolted to the top of the screening bucket 101. A through hole is opened on the top of the bucket cover 118. A second motor 103 is detachably connected to the top of the bucket cover 118. The main shaft of the second motor 103 passes through the through hole.
[0031] The screening barrel 101 is detachably connected to a clamp 119, and a screen plate 106 is clamped on the top of the clamp 119. The clamp 119 can fix the screen plate 106 to prevent misalignment. The screen plate 106 can screen out larger lumps of refractory castable. Then, the second motor 103 drives the crushing blades 105 to crush the larger lumps, preventing the larger lumps from causing wear on the inner wall of the conveying pipe 100 and improving the service life of the device. One end of the screening barrel 101 is provided with a feeding port, and one end of the feeding port is fixedly connected to a feeding pipe 120. The feeding pipe 120 is used to add refractory castable into the screening barrel 101 by the upstream process equipment (not shown in the figure).
[0032] A connecting seat is welded to one side of the conveying pipe 100. A mounting seat 111 is bolted to one side of the connecting seat. A cover plate 121 is detachably connected to one end of the mounting seat 111. A cylinder 112 is detachably connected to one end of the mounting seat 111. A transmission component 113 is detachably connected to one end of the cylinder 112. Two sets of first limiting grooves 122 are provided in the mounting seat 111. Limiting protrusions are provided at the top and bottom of the transmission component 113. Two sets of second limiting grooves 123 are provided on one side of the transmission component 113.
[0033] A first transmission wheel 124 is fixedly connected to one side of the first baffle 109, and a second transmission wheel 125 is fixedly connected to one side of the second baffle 110. Both the first transmission wheel 124 and the second transmission wheel 125 are provided with transmission cams. When the user closes the connection between the conveying pipe 100 and the screening barrel 101, the transmission component 113 can be moved along the first limiting groove 122 by the cylinder 112. The transmission component 113 drives the first baffle 109 and the second baffle 110 to rotate through the transmission cams on the first transmission wheel 124 and the second transmission wheel 125, which can close the connection between the conveying pipe 100 and the screening barrel 101 so that the residual material adsorbed on the inner wall of the conveying pipe 100 can be blown out by the blower 114. The first baffle 109 and the second baffle 110 can prevent the blower 114 from blowing the residual material into the screening barrel 101.
[0034] Two sets of limiting protrusions are respectively locked in two sets of first limiting grooves 122, and two sets of transmission protrusions are respectively locked in two sets of second limiting grooves 123.
[0035] One end of the conveying pipe 100 is detachably connected to an inner lining pipe 108. The inner lining pipe 108 rubs against the refractory castable. After the inner lining pipe 108 wears out, it can be quickly replaced. Compared with replacing the entire conveying pipe 100, this is more economical and reduces the maintenance cost of the device.
[0036] A duct is welded to one side of the conveying pipe 100, and a blower 114 is bolted to one side of the duct. After the first baffle 109 and the second baffle 110 close the connection between the conveying pipe 100 and the screening bucket 101, the blower 114 can blow out the residual material in the conveying pipe 100, which improves the convenience of cleaning the device.
