Description

Technical Field

[0001] The invention relates to the technical field of bulk soda ash pouring equipment, in particular to a bulk soda ash pouring device for the glass industry. Background Art

[0002] At most glass factories, soda ash arrives in ton bags. For example, at our factory, vehicles enter the factory, check the scale, and then enter the integrated raw material warehouse. The bags are unloaded by forklifts and stored in a designated area of the warehouse pending random inspection and testing. For shipment, ton bags are transported twice daily by forklift to the hoist loading area in the raw material building. Finally, unloading workers use electric hoists to lift the ton bags of soda ash to the unloading area, where they are cut and manually unloaded. Once completed, the used ton bags are taken back to the warehouse, compacted, and packaged for separate disposal.

[0003] Since some ton bags are reused by manufacturers and then transported forklift twice after long-distance transportation, a large number of soda ash bags packaged in ton bags are broken or rotten during the unloading process. In addition, outsourcing service fees are required for the unloading of ton bag soda ash, secondary forklift transportation after delivery, and manual bag cutting and unloading. At the same time, a large amount of dust will be raised during the unloading process, which cannot be handled in time. Therefore, we need to provide a bulk soda ash unloading device for the glass industry. Summary of the Invention

[0004] The purpose of the present invention is to provide a bulk soda ash unloading device for the glass industry. By adopting a whole truck of bulk soda ash unloading, it can not only reduce the space occupied by the warehouse and the cost of unloading and forking, but also reduce the cost of manual bag cutting and unloading, and improve the efficiency of the soda ash unloading operation; by setting up dust-proof parts, dual dust protection of active adsorption and passive sealing is achieved, and the efficiency is significantly improved compared with the traditional single dust removal method.

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1-6 The present invention provides a technical solution: a bulk soda ash pouring device for the glass industry, comprising:

[0028] Unloading bin 1, enclosure wall 2, material receiving piece 3 and dustproof piece 4, the unloading bin 1 is embedded in the ground, the enclosure wall 2 is installed on the top of the unloading bin 1, the dustproof piece 4 is installed in the enclosure wall 2 to reduce dust leakage, the material receiving piece 3 is located in the enclosure wall 2 and installed on the top of the unloading bin 1, and is used to drain the bulk soda ash to the unloading bin 1;

[0029] The dust-proof part 4 includes a dust-proof soft leather curtain 41, a dust collecting cover 42, a dust collecting pipe 43 and a dust collector 44. The tops of the two dust collecting covers 42 are connected to the dust collecting pipe 43, and the two dust collecting covers 42 are located on the top of the unloading bin 1. One end of the two dust collecting pipes 43 is connected to the dust collector 44. The dust collector 44 sucks the air in the enclosure wall 2. A dust-proof soft leather curtain 41 is provided at an opening on one side of the enclosure wall 2.

[0030] Specifically, by adopting the method of unloading soda ash in bulk by truck, the space occupied by the warehouse can be reduced, the cost of unloading and forking can be reduced, the cost of manual bag cutting and unloading can be reduced, and the efficiency of the soda ash unloading operation can be improved; by setting the dustproof part 4, the dual dust protection of active adsorption and passive sealing is realized, and the efficiency is significantly improved compared with the traditional single dust removal method. The combination of the spray water curtain and the turbulent water tank 523 purifies the dust through the dual mechanism of water washing and inertial collision, which is especially suitable for water-soluble materials such as soda ash, and avoids the problem of secondary dust flying in dry dust removal.

[0031] The dust collector 44 includes a tube body 441, a centrifugal fan 442, a processing box 443 and a filter element 5. The air inlet end of the tube body 441 is connected to the air outlet ends of the two dust collecting pipes 43. The air outlet end of the tube body 441 is located in the processing box 443. The air inlet end of the centrifugal fan 442 is connected to the processing box 443 and is used to extract air from the processing box 443. The filter element 5 is located in the processing box 443 and filters the air discharged from the tube body 441.

[0032] Furthermore, the centrifugal fan 442 is located on one side of the treatment box 443. Starting the centrifugal fan 442 can extract the air in the treatment box 443, so that the external air enters the treatment box 443 through the pipe body 441 and the dust collecting pipe 43, thereby pumping the air in the retaining wall 2 into the treatment box 443, and providing a filter element 5 in the treatment box 443 to perform multi-stage filtration on the air entering the treatment box 443, and finally discharge the purified air.

[0033] The filter element 5 includes a sprayer 51 and a spoiler 52. The sprayer 51 is located in the treatment box 443 and is used to clean the gas discharged from the tube 441. The spoiler 52 is located on the top of the sprayer 51 and is located in the treatment box 443. It is further purified by the accumulated water. The spoiler 52 is used in conjunction with the centrifugal fan 442.

[0034] Specifically, a double filter of a sprayer 51 and a spoiler 52 is provided in the processing box 443, wherein the sprayer 51 is located below the spoiler 52 to clean the dust in the air. The cleaned air enters the spoiler 52 and is filtered again, which can also prevent the influence of debris on the centrifugal fan 442 and extend its service life. The moist air after cleaning by the sprayer 51 is more easily adsorbed by accumulated water, and the design of the spoiler 52 extends the gas-liquid contact time. The combination of the two forms a composite purification effect of water washing and collision, which is better than a single dust removal method.

[0035] The sprayer 51 includes a spray plate 511 and a water supply pipe 512. The spray plates 511 are fixedly installed on both sides of the inner wall of the treatment box 443, forming a double-layer water curtain in the treatment box 443. The surfaces of the two spray plates 511 are connected to the water supply pipe 512, and the water inlet end of the water supply pipe 512 is connected to the external water source.

[0036] Among them, the spray plates 511 on both sides of the processing box 443 spray water at the same time to form two water curtains perpendicular to the direction of the airflow. The dust is directly intercepted by the water curtain when passing through with the airflow. The double-layer structure extends the gas-liquid contact path (similar to "zigzag" filtration). The dust needs to pass through the water curtain multiple times to improve the adsorption efficiency. Soda ash (sodium carbonate) is easily soluble in water. The spray water can quickly dissolve dust particles to avoid dust accumulation in the equipment; at the same time, the water curtain can neutralize the alkalinity of soda ash dust and reduce corrosion to subsequent equipment. The sprayer 51 is used for pretreatment, and most of the dust (especially larger particles) is adsorbed and settled through the double-layer water curtain, reducing the load of the subsequent spoiler 52. The water source of the sprayer 51 is externally connected to the circulating water system (requires a matching filtering device) to reduce water resource consumption.

[0037] The spoiler 52 includes a plate 521, an air inlet 522, a water trough 523, and a spoiler set 524. The plate 521 is fixedly installed in the treatment box 443, and the air inlet 522 is set through the plate 521. The spoiler set 524 is set between the top of the plate 521 and the inner wall of the treatment box 443, and is used to change the air flow path so that the air is fully in contact with the accumulated water in the water trough 523. Both water troughs 523 are opened at the top of the plate 521.

[0038] It is worth noting that the spoiler group 524 forms an "S-shaped" channel, and the airflow is forced to turn multiple times when passing through, and the dust is adsorbed by the accumulated water. The two water storage tanks 523 on the top of the plate body 521 store the accumulated water after spraying, forming a "water seal" structure: after the airflow passes through the air inlet 522, it is first washed by spray water, and then comes into contact with the liquid surface of the water storage tank 523 when passing through the spoiler group 524, and the dust that is not captured is adsorbed by the accumulated water again.

[0039] The spoiler set 524 includes two upper plates 5241 and two lower plates 5242. The two lower plates 5242 are fixed to the top of the plate body 521, and the two upper plates 5241 are fixed to the inner wall of the processing box 443. The bottom of the upper plate 5241 is infinitely close to the liquid surface of the water tank 523.

[0040] It is worth noting that the bottom of the upper plate 5241 is close to the liquid surface of the water storage tank 523. When the air flow passes over the water surface, a water film is formed, and the contact area between the dust and the water film is increased. The air after spraying contacts the liquid surface of the water storage tank 523 through a tortuous channel, and the remaining fine dust (such as PM2.5) is further captured by the accumulated water, achieving multi-stage purification.

[0041] The material receiving member 3 includes a material receiving hopper 31 fixedly mounted on the top of the discharge bin 1, and two dust collecting covers 42 are both located on the top of the material receiving hopper 31. An opening 32 is provided between the top of the material receiving hopper 31 and the dust collecting covers 42 for pouring in bulk soda ash;

[0042] Specifically, the material discharge hopper 31 is fixed to the top of the discharge bin 1. Its funnel-shaped structure guides bulk soda ash to flow smoothly along the inner wall into the discharge bin 1, using gravity to reduce material accumulation and improve discharge efficiency. During discharge, dust is immediately captured by the dust hood 42 as soon as it escapes, preventing dust from spreading outside the enclosure wall 2. The dust hood 42 is located at the top of the material discharge hopper, close to the edge of the opening 32, and uses negative pressure suction to guide dust through the dust collection pipe 43 into the dust collector 44.

[0043] The two water storage tanks 523 are connected by a circulation tank 6, and the bottoms of the two water storage tanks 523 are provided with drainage valve pipes 7. The top and bottom of the treatment box 443 are provided with valve pipe parts, which are used for water replenishment and sewage discharge respectively.

[0044] Among them, the two water storage tanks 523 are connected through the circulation tank 6, and water can be added to one water storage tank 523. At the same time, the valve pipe part at the top of the treatment box 443 is used to add water to the water storage tank 523, and the valve pipe part at the bottom of the treatment box 443 is used to discharge sewage. At the same time, the treatment box 443 is sealed.

[0045] It also includes an adsorption member 8 for assisting in adsorbing dust inside the enclosure wall 2. The adsorption member 8 includes an open cover 81 installed on the inner wall of the enclosure wall 2. The top of the open cover 81 is provided with an inclined pipe 82 connected to the pipe body 441.

[0046] It is worth noting that the adsorption member 8 is provided to assist the adsorption effect, increase the adsorption area, and better absorb the dust in the enclosure wall 2 into the tube body 441.

[0047] The bottom of the open cover 81 and the dust collecting cover 42 are both provided with a protective net portion for intercepting debris;

[0048] A protective net is located at the bottom of the open hood 81 and the dust hood 42 to prevent large debris from being sucked in. The dustproof soft leather curtain 41 deforms when squeezed by the unloading vehicle and resets when the unloading vehicle leaves. Although a small amount of dust will escape due to the high elasticity and tear resistance of the dustproof soft leather curtain 41, when squeezed by the unloading bucket, the curtain body deforms due to its flexible structure and wraps around the outer wall of the unloading bucket, forming a dynamic sealing surface. This material property not only prevents damage to the unloading equipment caused by hard contact, but also reduces the extrusion gap through deformation adaptability.

[0049] After the truck is unloaded and leaves, the soft leather curtain quickly resets itself due to the elasticity of the material itself. The wrinkles on the surface of the curtain automatically stretch during the reset process, and re-form a sealed curtain perpendicular to the opening of the retaining wall 2. It is worth noting that the dust escape at the moment of squeezing mainly comes from two parts: one is the "piston effect" caused by squeezing the curtain when the unloading bucket is inserted, causing a small amount of dust to overflow with the airflow; the other is the escape channel formed by the tiny gap between the curtain and the unloading bucket, but the rapid reset of the soft leather curtain can close the gap within 0.1 seconds, controlling the amount of escaping dust to less than 0.5% of the total dust amount of a single dumping.

[0050] The centrifugal fan 442, drain valve and valve pipe part involved in this application are all implemented using existing mature technologies and are conventional technical means in this field, so their specific circuit connections, control logic and work processes will not be described in detail.

[0051] After the vehicle transporting bulk soda ash of this device enters the factory and is weighed, it is driven directly to the discharge port of the soda ash elevator, and the dust-proof soft leather curtain 41 is pulled up and closed. After starting the on-site equipment, the driver controls the unloading of the vehicle and discharges the material from the discharge hopper 31 into the discharge bin 1. The bulk soda ash is poured into the discharge bin 1 through the top opening of the discharge hopper 31, and the funnel-shaped structure is used to drain the soda ash into the discharge bin 1 embedded in the ground, realizing the centralized storage of materials. The enclosure wall 2 surrounds the top of the discharge bin 1, and the dust-proof soft leather curtain 41 at the opening reduces the dust overflow during discharge through flexible shielding, forming a preliminary sealed environment. The wall 2 surrounds the top of the unloading bin 1. The dust-proof soft leather curtain 41 at the opening reduces the dust overflow during unloading through flexible shielding, forming a preliminary sealed environment. The spray plate 511 on the inner wall of the processing box 443 forms a double-layer water curtain through the water supply pipe 512. When the dust-laden air passes through the water curtain, the dust is adsorbed and settled by the water. The air cleaned by the spray enters the spoiler 52, changes its flow direction through the tortuous channel composed of the upper plate 5241 and the lower plate 5242, and fully contacts the accumulated water in the water trough 523. The residual dust is further adsorbed, and the purified air is discharged by the centrifugal fan 442.

[0052] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
