Description

Technical Field

[0001] This utility model relates to the technical field of ash dish transfer equipment, and in particular to an ash dish clamping device. Background Technology

[0002] Pyrometallurgical assays are not only a method for enriching gold and silver, but also an important tool for gold and silver analysis. Their accuracy in determining the gold content in high-content gold raw materials or pure gold is superior to other methods. Therefore, gold and silver smelters both domestically and internationally regard them as the most reliable analytical method.

[0003] Pyrometallurgy mainly consists of three stages: smelting, ash blowing, and gold separation. During the smelting process, lead is used to capture gold, silver, and other precious metals in a molten state, forming lead rings in a crucible. The lead rings sink to the bottom of the crucible. During the ash blowing process, the smelted lead rings are placed in an ash pan and ash blown in a muffle furnace to remove the lead. During ash blowing, the lead is oxidized to lead oxide and penetrates into the porous ash pan, thereby removing the lead from the lead rings.

[0004] Placing ash trays into the muffle furnace requires the use of ash tray clamps. Most existing ash tray clamps require manual pressure from the user to clamp the ash trays. However, the temperature of the ash trays and the muffle furnace is high. During the continuous transfer of multiple ash trays, the temperature of the ash tray clamps gradually increases, which leads to unstable clamping of the ash trays when the user holds them. Summary of the Invention

[0005] To address the problem of unstable clamping of ash pans during manual ash pan holding as the temperature of the clamp gradually increases, this invention proposes an ash pan holding device. The device uses clamping seats that come close together to contact the ash pan, and then uses a limiting component to fix the position of the clamping seats, thereby holding the ash pan in place without the need for manual clamping, thus reducing the probability of accidents.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: A ash dish clamping device includes a placement plate with a through groove for the ash dish to pass through. A mounting plate is fixed to the placement plate, and a handle is fixed to the side of the mounting plate away from the through groove. Two horizontally slidable racks are mounted on the mounting plate. A sleeve is fitted onto the handle, and a toothed ring is fixed to the end of the sleeve near the mounting plate. The toothed ring is located between and engages with the two racks, allowing the two racks to move closer or further apart as the toothed ring rotates. A limiting component is provided on the sleeve to limit the rotation of the toothed ring. Support rods are fixed to the sides of the two racks near the through groove, and clamping seats are fixed to the ends of the support rods near the through groove. The opposing sides of the two clamping seats contact the side of the ash dish, clamping it. When the opposing sides of the clamping seats contact the side of the ash dish, the limiting component restricts the rotation of the sleeve on the handle, preventing the toothed ring from continuing to rotate. At this time, the racks will no longer slide, thus positioning the two clamping seats.

[0007] Preferably, the mounting plate has a first sliding groove and a second sliding groove, which are connected and extend through the mounting plate. The side of the first sliding groove covers the side of the second sliding groove. A slider is slidably disposed in the first sliding groove. A sliding rod passes through the slider and the rack, with one end of the sliding rod passing through the second sliding groove and the other end passing through the rack, both ends of which are screwed with nuts. The support rod is fixed to the side of the slider away from the rack and passes through the second sliding groove. The nut at the end of the sliding rod near the through groove abuts against the side of the mounting plate, thereby preventing the slider and rack from disengaging.

[0008] Preferably, the limiting component includes a screw, and a screw hole is provided on the sleeve. The screw is screwed into the screw hole, and its end contacts the outer side of the handle. When the screw abuts against the outer wall of the handle, the sleeve can no longer rotate. Loosening the screw allows the sleeve to rotate again.

[0009] Preferably, a limiting sleeve is also fixedly sleeved on the handle, with one end of the limiting sleeve contacting the end of the sleeve away from the mounting plate.

[0010] Preferably, the rack is located on the side of the mounting plate away from the through slot.

[0011] Preferably, a cover is fixed to one side of the mounting plate, and both the handle and the sleeve pass through a through hole opened on the cover.

[0012] Preferably, the two sides of the ash dish near the clamping seat are inclined surfaces, and its longitudinal section is inverted "V" shape.

[0013] Preferably, the clamping seat includes a first clamping part and a second clamping part, the first clamping part contacting the side of the ash dish, and the lower bottom surface of the second clamping part contacting the upper top surface of the ash dish. This reduces the probability of the ash dish falling off.

[0014] The beneficial effects of this utility model through the above technical solution are as follows: 1. In this utility model, the rotation of the sleeve causes the two racks meshing with the gear ring to move closer or further apart. When the two racks move closer together, the clamping seats on the two support rods come into contact with the side of the ash dish. The limiting component limits the sleeve to prevent it from rotating, thereby achieving the clamping of the ash dish by the clamping seat. At this time, the device can be moved manually by holding the handle, without the need for manual force to clamp the ash dish, reducing the probability of accidents.

[0015] 2. The mounting plate of this utility model is provided with a first sliding groove and a second sliding groove. The slider in the first sliding groove and its side rack are restricted by the nuts at both ends of the sliding rod to ensure the stability of the rack sliding left and right on the mounting plate.

[0016] 3. In this utility model, the screw is screwed into the screw hole on the sleeve, so that when the screw abuts against the outer side of the handle, the sleeve cannot rotate relative to the handle again. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figures 1-5 As shown, this embodiment provides an ash dish clamping device, including a placement plate 1. The placement plate 1 has a through groove 2 for the ash dish 100 to pass through. In this embodiment, as shown... Figure 5The front view of the ash dish 100 is an inverted isosceles trapezoid. A mounting plate 3 is welded and fixed on the placement plate 1. A handle 200 is welded and fixed on the side of the mounting plate 3 away from the through groove 2. The handle 200 is cylindrical. Two racks 4 that can slide left and right are provided on the mounting plate 3. The two racks 4 are distributed vertically and horizontally. The teeth of the two racks 4 are arranged opposite each other. The racks 4 are located on the side of the mounting plate 3 away from the through groove 2.

[0020] For details, please refer to Figure 2 and Figure 3 The mounting plate 3 has a first sliding groove 9 and a second sliding groove 10, which are connected and pass through the mounting plate 3. The side of the first sliding groove 9 covers the side of the second sliding groove 10, thus restricting the forward movement of the slider 11. The slider 11 is slidably disposed in the first sliding groove 9. A sliding rod 12 passes through the slider 11 and the rack 4. One end of the sliding rod 12 passes through the second sliding groove 10, and the other end passes through the rack 4, with nuts 13 screwed to both ends. Support rods 7 are fixed on the side of the two racks 4 near the through groove 2. The support rods 7 are fixed on the side of the slider 11 away from the rack 4 and pass through the second sliding groove 10. The nut 13 at the end of the sliding rod 12 near the rack 4 contacts the rack 4, and the nut 13 at the end of the sliding rod 12 near the slider 11 contacts the side of the mounting plate 3, thus achieving the stability of the rack 4 moving left and right on the mounting plate 3.

[0021] Further, refer to Figure 2 A sleeve 5 is fitted onto the handle 200. A toothed ring 6 is fixed to one end of the sleeve 5 near the mounting plate 3. The toothed ring 6 is fixedly fitted onto the sleeve 5. The toothed ring 6 is located between the two racks 4 and meshes with the two racks 4, so that when the toothed ring 6 rotates, the two racks 4 move closer or further apart.

[0022] For details, please refer to Figure 1 The sleeve 5 is provided with a limiting component to limit the rotation of the gear ring 6. The limiting component includes a screw 14. The sleeve 5 has a screw hole. The screw 14 is screwed into the screw hole and its end contacts the outer side of the handle 200. When the screw 14 is tightened, the sleeve 5 can no longer rotate. When the screw 14 is loosened, the sleeve 5 can rotate again, thereby positioning the two gear racks 4.

[0023] Meanwhile, a limiting sleeve 15 is also fixedly sleeved on the handle 200. It can be fixed by spot welding. One end of the limiting sleeve 15 contacts the end of the sleeve 5 away from the mounting plate 3, thereby preventing the sleeve 5 from moving back and forth on the handle 200.

[0024] Further, refer to Figure 3 and Figure 4A clamping seat 8 is fixed to one end of the support rod 7 near the through groove 2. The opposite sides of the two clamping seats 8 contact the side of the ash dish 100 to clamp the ash dish 100. The two support rods 7 are at different heights, and the clamping seats 8 are fixed to their opposite sides to achieve the same height for clamping the ash dish 100.

[0025] For details, please refer to Figure 5 The ash dish 100 has two beveled sides near the clamping seat 8, and its longitudinal section is inverted "V" shape. The clamping seat 8 includes a first clamping part 16 and a second clamping part 17. The first clamping part 16 contacts the side of the ash dish 100, and the lower bottom surface of the second clamping part 17 contacts the upper top surface of the ash dish 100. After the rack 4 is positioned, the clamping seat 8 stably clamps the ash dish 100.

[0026] Furthermore, a cover 300 is fixed to one side of the mounting plate 3, and both the handle 200 and the sleeve 5 pass through through holes opened in the cover 300. This protects the rack 4 and the gear ring 6.

[0027] When using this device, first insert it into the muffle furnace, manually hold the handle 200 and the limiting cylinder 15, and then place the placement plate 1 flat on the placement plate in the muffle furnace. At this time, the ash dish 100 on the placement plate of the muffle furnace extends out of the placement plate 1 through the through groove 2. Then loosen the screw 14, rotate the sleeve 5, and the two racks 4 move closer to each other, thereby driving the clamping seats 8 on the two support rods 7 to move closer to each other. At this time, the first clamping part 16 contacts the side of the ash dish 100, and the second clamping part... The bottom surface of the holding part 17 contacts the top surface of the ash dish 100. Tighten the screw 14 to fix the position of the rack 4 and the clamping seat 8, thus completing the clamping of the ash dish 100. At this time, the device and the ash dish 100 can be moved out of the muffle furnace by manually holding the handle 200 and the limiting cylinder 15. Then, the ash dish 100 is moved to the next process. After being placed stably, the screw 14 is loosened and the sleeve 5 is rotated. The two racks 4 and the clamping seat 8 move away from each other, thus completing the transfer of the ash dish 100.
