Description

Technical Field

[0001] This invention relates to the field of material tank technology, specifically to a material tank for storing coal washing reagents. Background Technology

[0002] In the coal washing process, reagent storage tanks are key equipment for the safe and efficient storage and addition of chemical reagents. Their design strictly meets the requirements of explosion-proof, spontaneous combustion-proof, moisture-proof, and wear-proof.

[0003] Existing storage tanks are used to store granular flocculants. During storage, the upper part of the tank is designed as a vertical cylindrical body to ensure the storage volume, while the lower part is designed as a conical hopper to promote the flow of materials during discharge.

[0004] While the aforementioned storage tank can effectively store granular flocculants, the physical properties of these flocculants result in low particle hardness. Consequently, during storage, the smaller amount of material in the lower conical hopper must withstand the pressure of the larger amount of material in the upper cylindrical section. This makes the material in the lower conical area more susceptible to crushing during storage. Consequently, the broken flocculants dissolve too quickly during subsequent use, leading to excessively high local concentrations and affecting the performance and effectiveness of the agent.

[0005] Therefore, this invention proposes a storage tank for coal washing reagents to solve the above problems. Summary of the Invention

[0006] In view of this, the technical problem to be solved by the present invention is to provide a storage tank for coal washing reagents, so as to solve the problems in the prior art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a coal washing reagent storage tank, including a mounting frame, a tank body fixedly connected between the mounting frames, a feed pipe fixedly connected to the outer surface of the tank body, and a discharge pipe fixedly connected to the bottom of the tank body. Both the feed pipe and the discharge pipe are connected to the tank body. The tank body also includes a support mechanism for reducing the pressure on the materials stored at the conical bottom of the tank body.

[0008] The support mechanism includes two semi-circular disks fixedly connected to the tank body. Two fixed rods are fixedly connected between the two semi-circular disks. Switch plates are slidably connected to opposite sides of the two semi-circular disks. The top of each semi-circular disk and each fixed rod is inclined to allow material located at the top of the semi-circular disk and the fixed rod to slide towards the switch plate through the inclined plane. A connector is fixedly connected between the two semi-circular disks. The support mechanism includes a drive assembly for driving the two switch plates to slide. When the switch plates slide, they can block the material on the semi-circular disks and the fixed rods.

[0009] Preferably, the drive assembly includes a rotating shaft, which is rotatably connected to a connector and passes through the connector. A gear is fixedly sleeved on the outer surface of the rotating shaft. Racks are fixedly connected to the top of the two switch plates respectively, and both racks mesh with the gear and are located on both sides of the gear. A drive source is fixedly connected to the top of the tank. The output end of the drive source is fixedly connected to the rotating shaft for driving the rotating shaft to rotate. When the rotating shaft rotates, the two switch plates can be driven to move away from or closer to each other through the cooperation of the gear and rack.

[0010] Preferably, the top of the connector is arc-shaped to reduce the amount of material retained on the connector.

[0011] Preferably, both switch plates are inclined on opposite sides.

[0012] Preferably, the support mechanism further includes a material guiding assembly for cooperating with the drive assembly to reduce material retention on the semi-circular disk. The material guiding assembly includes two material guiding discs inclinedly disposed on the top of the semi-circular disk. At least two through rods are fixedly connected to the bottom of each semi-circular disk, and at least four guide posts are fixedly connected to the bottom of each semi-circular disk. The guide posts are slidably connected to the semi-circular disk. Each through rod is set as an inclined surface on the side near the switch plate. When the switch plate slides towards the through rod, it can drive the material guiding disc to slide upward through cooperation with the through rod.

[0013] Preferably, the side of the switch plate near the through rod is set as an inclined surface to reduce the stress between it and the through rod when in contact with it.

[0014] Preferably, the drive source is a servo motor.

[0015] Preferably, an auxiliary mechanism is also included for filtering and agitating the material inside the tank. The auxiliary mechanism includes a filter screen slidably connected to the discharge pipe, and the filter screen is inclined.

[0016] Preferably, a protrusion is fixedly connected to the outer surface of the rotating shaft. The protrusion is located at the bottom of the filter screen and is hemispherical. When the rotating shaft rotates, the filter screen can be pushed up and down by the protrusion.

[0017] Preferably, the rotating shaft is hollow, and multiple air holes are opened on the outer surface of the rotating shaft, with a protective net fixedly connected to each air hole.

[0018] Compared with the prior art, the present invention provides a storage tank for coal washing reagents, which has the following beneficial effects:

[0019] 1. The present invention, through the setting of the support mechanism, forms a closed blocking surface with the cooperation of the semi-circular disk, the fixed rod and the closed switch plate. When the material continues to enter the tank, the material will no longer come into contact with the material at the bottom, thereby allowing the material to be layered within the support mechanism. This reduces the pressure on the material at the bottom of the tank during storage, effectively avoiding the pressure on the granular flocculant stored at the bottom of the tank, and ensuring its performance and effect in subsequent use.

[0020] 2. This invention enables the guide plate to vibrate up and down during material discharge by cooperating with the drive assembly, switch plate, and through rod, thereby preventing material from lingering on the guide plate. At the same time, the up and down vibration of the guide plate improves the smoothness of material discharge and effectively avoids material jamming.

[0021] 3. The present invention, through the setting of auxiliary mechanism, allows incomplete material particles to leak out from the filter screen, further improving the quality of material discharge. Furthermore, the rotating shaft drives the protrusion to rotate back and forth, so that the protrusion and the filter screen cooperate, and the protrusion pushes the lower side of the filter screen, causing the filter screen to vibrate up and down, thereby improving the smoothness of material discharge at the discharge pipe.

[0033] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, some features described in the examples may be combined in other examples.

[0034] like Figures 1 to 7 As shown, this embodiment provides a coal washing reagent storage tank, including a mounting frame 100, a tank body 200 fixedly connected between the mounting frames 100, a feed pipe 201 fixedly connected to the outer surface of the tank body 200, and a discharge pipe 202 fixedly connected to the bottom of the tank body 200. Both the feed pipe 201 and the discharge pipe 202 are connected to the tank body 200. It also includes a support mechanism 300 for reducing the pressure on the materials stored at the conical bottom of the tank body 200.

[0035] Both the feed pipe 201 and the discharge pipe 202 are equipped with valves. During feeding, the valve on the feed pipe 201 opens, and the material enters the tank 200. During discharge, the valve on the discharge pipe 202 opens, and the material is discharged from the discharge pipe 202. The discharge pipe 202 is L-shaped, with its lower end inclined.

[0036] The support mechanism 300 includes two semi-circular disks 301 fixedly connected to the tank body 200. Two fixed rods 302 are fixedly connected between the two semi-circular disks 301. Switch plates 303 are slidably connected to opposite sides of the two semi-circular disks 301. The top of each semi-circular disk 301 and each fixed rod 302 is inclined to allow material on the top of the semi-circular disks 301 and fixed rods 302 to slide towards the switch plate 303 through the inclined surface. A connector 304 is fixedly connected between the two semi-circular disks 301. The support mechanism 300 includes a drive assembly for driving the two switch plates 303 to slide. When the switch plates 303 slide, they can block the material on the semi-circular disks 301 and fixed rods 302.

[0037] The drive assembly includes a rotating shaft 305, which is rotatably connected to a connector 304 and passes through the connector 304. A gear 306 is fixedly sleeved on the outer surface of the rotating shaft 305. Two racks 307 are fixedly connected to the top of the two switch plates 303 respectively, and both racks 307 mesh with the gears 306 and are located on both sides of the gears 306. A drive source 308 is fixedly connected to the top of the tank body 200. The output end of the drive source 308 is fixedly connected to the rotating shaft 305 and is used to drive the rotating shaft 305 to rotate. When the rotating shaft 305 rotates, the two switch plates 303 can be driven to move away from or closer to each other through the cooperation of the gears 306 and the racks 307. The drive source 308 is a servo motor.

[0038] Through the implementation of this embodiment, the semi-circular disc 301, the fixing rod 302, and the closed switch plate 303 work together to form a closed blocking surface, effectively avoiding the pressure on the granular flocculant stored at the bottom of the tank 200, and ensuring its performance and effect in subsequent use.

[0039] Furthermore, the top of the connector 304 is designed to be arc-shaped to reduce the amount of material retained on the connector 304, making it easier for the material to slide off the connector 304.

[0040] Furthermore, both switch plates 303 are inclined on opposite sides, so that when they are turned on, the inclined surfaces make it easier for materials to fall off.

[0041] Optionally, the two switch plates 303 can be configured with a sawtooth shape on opposite sides, so that the sawtooth shape interlocks with each other when closed, improving the fixing effect after closing. However, the sawtooth design makes it more prone to wear, so it needs to be replaced regularly.

[0042] Furthermore, the support mechanism 300 also includes a material guiding assembly for cooperating with the drive assembly to reduce material retention on the semi-circular disk 301. The material guiding assembly includes two guide discs 309 inclinedly disposed on the top of the semi-circular disk 301. At least two through rods 310 are fixedly connected to the bottom of each semi-circular disk 301, and at least four guide posts 311 are fixedly connected to the bottom of each semi-circular disk 301. The guide posts 311 are slidably connected to the semi-circular disk 301. Each through rod 310 is set with an inclined surface on the side near the switch plate 303. When the switch plate 303 slides towards the through rod 310, it can drive the guide disc 309 to slide upward through cooperation with the through rod 310. Through cooperation with the drive assembly, the guide disc 309 vibrates up and down, thereby preventing material from staying on the guide disc 309. At the same time, the up and down vibration of the guide disc 309 can improve the smoothness of material discharge and effectively avoid material jamming.

[0043] Furthermore, the switch plate 303 is configured with a bevel on the side near the through rod 310 to reduce the stress between it and the through rod 310 when in contact with it, thereby improving its service life.

[0044] It also includes an auxiliary mechanism 400 for filtering and pushing the material in the tank 200. The auxiliary mechanism 400 includes a filter screen 401 that is slidably connected to the discharge pipe 202. The filter screen 401 is inclined.

[0045] The implementation of this embodiment allows incomplete particles to leak out of the filter screen 401, further improving the quality of the discharged material.

[0046] Furthermore, a protrusion 404 is fixedly connected to the outer surface of the rotating shaft 305. The protrusion 404 is located at the bottom of the filter screen 401 and is set as a hemispherical shape. When the rotating shaft 305 rotates, the filter screen 401 can be pushed up and down by the protrusion 404, which improves the smoothness of material discharge at the discharge pipe 202.

[0047] Furthermore, the rotating shaft 305 is hollow, and the bottom of the rotating shaft 305 can be fixed and connected to the air outlet of an external air pump. Multiple air holes 402 are opened on the outer surface of the rotating shaft 305, and a protective net 403 is fixedly connected in each air hole 402, which further improves the smoothness of material discharge. At the same time, the protective net 403 can prevent material from entering the air hole 402.

[0048] Optionally, the protective net 403 can be set as a baffle and slidably connected to the air hole 402, and a return spring is fixedly connected between the air hole 402. When not in use, the baffle can seal the air hole 402, and when in use, the spring is stretched by the push of the gas, thereby opening the air hole 402, improving the protection effect of the air hole 402.

[0049] The working principle of all the content in the above embodiments is as follows:

[0050] Initial state: The switch plates 303 are not close to each other and are located inside the semi-circular disk 301, and the inclined surface of the switch plate 303 is not in contact with the inclined surface of the through rod 310. The guide plate 309 is located on the upper surface of the semi-circular disk 301, and the bottom of the guide plate 309 is in contact with the bottom of the semi-circular disk 301. At the same time, the bottom end of the rotating shaft 305 is connected to the air outlet of the external air pump.

[0051] The following describes the working principle and beneficial effects of support mechanism 300:

[0052] When material enters tank 200 from feed pipe 201, it falls onto guide plate 309 and slides towards the center guided by guide plate 309 and fixing rod 302. Since there is no obstruction from switch plate 303, it can then enter the bottom of semi-circular disc 301. As the material enters tank 200, personnel can observe through the observation window of tank 200. When the material contacts the bottom of semi-circular disc 301, the drive source 308 can be activated. Figure 4 For reference, the output terminal of the drive source 308 rotates counterclockwise. The rotation of the output terminal of the drive source 308 drives the rotating shaft 305 to rotate synchronously. In turn, the rotating shaft 305 drives the gear 306 to rotate synchronously. Since the two racks 307 mesh with the rotating shaft 305 and are located on both sides of the two racks 307 respectively, the gear 306 and the rack 307 can drive the two switch plates 303 to move closer to each other and close the opening between the semicircular disks 301.

[0053] Furthermore, through the setting of the support mechanism 300, a closed blocking surface is formed between the semi-circular disk 301, the fixed rod 302, and the closed switch plate 303. When the material continues to enter the tank 200, the material will no longer come into contact with the material at the bottom, thus allowing the material to be layered within the support mechanism 300. This reduces the pressure on the material at the bottom of the tank 200 during storage, effectively avoiding the pressure on the granular flocculant stored at the bottom of the tank 200, and ensuring its performance and effectiveness in subsequent use.

[0054] Furthermore, when material needs to be discharged, as the material at the bottom of the semi-circular disk 301 decreases, the drive source 308 can be activated, causing the drive source 308 to drive the rotating shaft 305 to rotate clockwise. Then, with the cooperation of the rack 307 and the gear 306, the switch plate 303 moves away from each other and slides back into the semi-circular disk 301, opening the opening between the semi-circular disk 301 and the fixed rod 302. This allows the material above the semi-circular disk 301 to enter the bottom of the tank 200 and be discharged, thus ensuring the material discharge operation.

[0055] Furthermore, when material is discharged, after the switch plate 303 slides to its initial state, the drive source 308 is activated, causing the drive source 308 to rotate clockwise and counterclockwise at a set angle. Through the engagement of the gear 306 and rack 307, the switch plate 303 can slide back and forth within the semi-circular disk 301, causing the switch plate 303 to move closer to or away from the through rod 310. When it moves closer, the inclined surface of the switch plate 303 presses against the inclined surface of the through rod 310, causing the through rod 310 to... When the guide plate 309 slides upward and the switch plate 303 moves away from the through rod 310, the through rod 310 and the guide plate 309 can slide downward again under the action of gravity. Then, when the material is discharged, the guide plate 309 can vibrate up and down in cooperation with the drive component, the switch plate 303 and the through rod 310, thereby preventing the material from staying on the guide plate 309. At the same time, the up and down vibration of the guide plate 309 can improve the smoothness of material discharge and effectively avoid material jamming.

[0056] The following describes the working principle and beneficial effects of auxiliary mechanism 400:

[0057] Furthermore, during the material discharge process, when the material passes through the filter screen 401, the inclined filter screen 401 allows the material to be discharged from the discharge pipe 202. At the same time, the filter screen 401 allows incomplete particles to leak out, further improving the quality of the discharged material. Meanwhile, when the drive source 308 is activated to drive the rotating shaft 305 to rotate reciprocally, the rotating shaft 305 drives the protrusion 404 to rotate reciprocally, causing the protrusion 404 to move closer to or further away from the lower side of the inclined filter screen 401. The push of the protrusion 404 on the lower side of the filter screen 401 causes the filter screen 401 to vibrate up and down, thereby improving the smoothness of the discharge at the discharge pipe 202.

[0058] In addition, when the tank 200 needs to discharge material, an external air pump can be started simultaneously. The input of gas by the external air pump allows the gas to pass through the hollow rotating shaft 305 and be discharged from the air hole 402. The gas blown out through the air hole 402 can act between the materials to prevent the material from arching due to pressure. At the same time, the reciprocating rotation of the rotating shaft 305 improves the range and uniformity of the air jet, thereby further improving the smoothness of material discharge. Meanwhile, the protective net 403 can prevent material from entering the air hole 402.

[0059] The embodiments of the present invention have been described above. However, the embodiments are not limited to the specific implementation methods described above. The specific implementation methods described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the embodiments described above, all of which are within the protection scope of the embodiments described above.
