Description

Technical Field

[0001] This invention relates to the field of coal slime treatment technology, specifically to a coal slime collection system and treatment process. Background Technology

[0002] The underground coal slime sorting and collection device is a mining equipment used to collect coal slime from the bottom of the underground water sump in coal mines and separate large-sized impurities from the slime. This device separates large-sized impurities from the coal slime, improving its purity and providing pretreatment for the next stage of coal slime processing. The coal slime is transported from the pretreatment equipment to a mixing tank for stirring. The uniformly stirred coal slime is then pumped to a filter press for further processing. Unscreened coal slime contains impurities of varying particle sizes, and large-sized impurities can cause varying degrees of wear or damage to equipment such as the coal slime conveying pump and filter press.

[0003] Furthermore, during the coal slime collection process, a large amount of coal gas is present in the coal slime. During the collection process, the coal gas is transported to various devices along with the coal slime. During the coal slime processing, the coal gas is released. If the released coal gas is released, it will not only pollute the air but may also cause a gas leak accident, creating a safety hazard. The coal gas can be used as fuel, which will also result in energy waste. If a blower is used to discharge the coal gas from the system, the blower's air pressure will create a negative pressure in the system, affecting the transportation of coal slime and causing inconvenience. These are all problems in this industry.

[0004] Therefore, we urgently need a solution to the above problems. Summary of the Invention

[0016] As a further technical solution, all the switching elements have a semi-toothed portion, and the switching assembly also includes,

[0017] A driving member is rotatably mounted on the fixed member. The driving member has an internal tooth portion, and a half-tooth portion meshes with the internal tooth portion. The rotation of the driving member drives the switching member to rotate along the hinge point through the half-tooth portion.

[0018] As a further technical solution, the tank also has a first discharge port; and further includes,

[0019] An impeller is rotatably disposed within the first through hole, and the impeller rotates radially about the first through hole.

[0020] A drive shaft is rotatably mounted on the tank body, and one end of the drive shaft is connected to the impeller.

[0021] A wheel is disposed at the other end of the transmission shaft. The wheel cooperates with the driving component, and the rotation of the transmission shaft drives the driving component to rotate.

[0032] A coal slime collection and treatment process includes the following steps:

[0034] S2. In the coal slime collection system, stones in the coal slime are separated and coal gas during transportation is collected;

[0035] S3. Use a filter press to separate the solids and liquids in the coal slime after separation in S2;

[0036] S4. Collect and store the solids separated in S3 as raw materials for coal bricks, and use the liquid separated in S3 for the preparation of water gas.

[0037] As a further technical solution, the gas separated from S2 is dried and used as blast furnace fuel.

[0038] The working principle and beneficial effects of this invention are as follows:

[0039] In this invention, a coal slime collection system includes a tank, a separation device, and a sliding member. The tank has a collection chamber and a buffer chamber, which are connected by a first through hole. The separation device is installed on the tank, and the sliding member is slidably installed in the buffer chamber. The sliding member and the tank form a gas collection space, which is connected to the collection chamber by the first through hole. The sliding member can increase or decrease the gas collection space by sliding.

[0040] During operation, the cleaning machine collects and stores the coal slurry from underground, then transports it through pipelines to the inlet of the tank. The coal slurry enters the separation device from the inlet, where it separates impurities. The coal slurry falls into the tank, while the impurities are sent to the outside for collection and processing through the outlet of the separation device. As the coal slurry enters the tank, the sliding component slides within the buffer chamber, increasing the gas collection space. This allows gas from the collection chamber to enter the gas collection space through the first through-hole. As the gas enters the gas collection space, the pressure in the collection chamber decreases, allowing the coal slurry at the inlet to enter the collection chamber. When separation is complete and discharge is required, the first outlet opens, and the sliding component reduces the gas collection space. At this time, the inlet closes, and the pressure in the collection chamber increases, forcing the screened coal slurry out through the first outlet, making the pressing process more convenient. The screened coal slurry and gas are then processed separately.

[0041] Beneficial effects: By sliding the sliding parts to change the size of the gas collection space, the pressure inside the collection chamber can be changed. This not only allows for the absorption and treatment of coal gas, but also assists in the feeding and discharging of materials inside the tank, increasing the efficiency of feeding and discharging, and reducing the impact of coal gas on coal slime treatment.

[0048] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0049] like Figures 1-4 As shown, this embodiment proposes a coal slime collection system, including,

[0050] Tank 1, wherein the tank 1 has a collection chamber 101,

[0051] Separation device 2, which is installed on the tank body 1.

[0052] The tank body 1 also has a buffer cavity 102, the buffer cavity 102 and the collection cavity 101 are connected through a first through hole 103; it also includes,

[0053] Sliding member 3 is slidably disposed in the buffer cavity 102. The sliding member 3 and the tank body 1 form a gas collection space 4. The gas collection space 4 is connected to the collection cavity 101 through the first through hole 103. The sliding member 3 slides to increase or decrease the gas collection space 4.

[0054] In this embodiment, a coal slime collection system includes a tank 1, a separation device 2, and a sliding member 3. The tank 1 has a collection chamber 101 and a buffer chamber 102. The buffer chamber 102 and the collection chamber are connected through a first through hole 103. The separation device 2 is disposed on the tank 1. The sliding member 3 is slidably disposed in the buffer chamber 102. The sliding member 3 and the tank 1 form a gas collection space 4. The gas collection space 4 is connected to the collection chamber 101 through the first through hole 103. The sliding member 3 slides to increase or decrease the gas collection space 4.

[0055] During operation, the cleaning machine collects and stores the coal sludge from underground, then transports it through pipelines to the inlet 105 of tank 1. The coal sludge enters the separation device 2 from the inlet 105, where it separates impurities. The coal sludge falls from the separation device 2 into tank 1, while the impurities are sent to the outside for collection and processing through the outlet of the separation device 2. As the coal sludge enters tank 1, the sliding member 3 slides within the buffer chamber 102, increasing the gas collection space 4 within the buffer chamber 102, allowing the gas in the collection chamber 101 to pass through the... A through-hole 103 enters the gas collecting space 4. When the gas in the collecting chamber 101 enters the gas collecting space 4, the pressure in the collecting chamber 101 decreases, causing the coal slime at the feed inlet 105 to enter the collecting chamber 101. When the separation is complete and discharge is required, the first discharge port 106 opens, and the sliding member 3 slides to reduce the gas collecting space 4. At this time, the feed inlet 105 will close, and the pressure in the collecting chamber 101 will increase, causing the screened coal slime to be pressed out from the first discharge port 106, making the pressing more convenient. The screened coal slime and gas are processed separately.

[0056] The size of the gas collection space 4 is changed by sliding the slider 3, thereby changing the pressure in the collection chamber 101. This can not only absorb and treat the coal gas, but also assist the feeding and discharging of the material in the tank 1, increase the efficiency of feeding and discharging, and reduce the impact of coal gas on coal slime treatment.

[0057] Furthermore, the tank body 1 also has an air outlet 104, which connects the buffer cavity 102 and the outside of the tank body 1. The sliding member 3 slides to block the air outlet 104, and the sliding member 3 slides to connect or disconnect the air outlet 104 from the gas collection space 4.

[0058] In this embodiment, the tank 1 also has an air outlet 104, which connects the buffer chamber 102 and the outside of the tank 1. The sliding member 3 slides to block the air outlet 104. The sliding member 3 slides to connect or disconnect the air outlet 104 from the gas collection space 4. During operation, when the sliding member 3 slides, the gas collection space 4 gradually increases. When the air outlet 104 is not connected to the gas collection space 4, the gas in the tank 1 will continuously enter the gas collection space 4. When the sliding member 3 slides past the air outlet 104, the air outlet 104 connects to the gas collection space 4, connecting the gas collection space 4 with the outside of the tank 1, thereby venting the gas in the gas collection space 4. When the gas collection space 4 decreases, the sliding member 3 moves in the opposite direction. By sliding the sliding member 3, the connection between the gas collection space 4 and the outside is controlled, realizing the air outlet and air inlet. The structure is simple and the control is convenient.

[0059] Furthermore, the tank body 1 also has a feed inlet 105; it also includes a switch assembly 5, which is disposed on the feed inlet 105, and the switch assembly 5 includes,

[0060] Fixing member 51 is disposed on the feed inlet 105, and the fixing member 51 has a second through hole 511 communicating with the feed inlet 105.

[0061] There are several switch components 52, one end of each of the several switch components 52 is hinged to the fixing member 51, and each of the switch components 52 is located between the second through hole 511 and the feed inlet 105. The several switch components 52 rotate along the hinge point to open or close the second through hole 511 and the feed inlet 105.

[0062] In this embodiment, the tank body 1 also has a feed inlet 105; it also includes a switch assembly 5, which is disposed on the feed inlet 105. The switch assembly 5 includes a fixing member 51 and a switch member 52. The fixing member 51 is disposed on the feed inlet 105 and has a second through hole 511 communicating with the feed inlet 105. There are several switch members 52, one end of which is hinged to the fixing member 51. The switch members 52 are located between the second through hole 511 and the feed inlet 105. The several switch members 52 rotate along the hinge point to make the first switch member 52 rotate. The second through hole 511 is open or closed with the feed inlet 105. During operation, the fixing member 51 is fixed on the feed inlet 105. The second through hole 511 of the fixing member 51 is connected to the feed inlet 105. Several switching members 52 block the second through hole 511 together. When the switching member 52 rotates along the hinge point, the second through hole 511 and the feed inlet 105 can be connected, thereby realizing feeding. When the tank 1 needs to discharge, the switching members 52 will rotate together toward the second through hole 511, thereby blocking the second through hole 511, so that the raw materials in the tank 1 can be sent out in time.

[0063] Furthermore, each of the switching elements 52 has a semi-tooth portion 521, and the switching assembly 5 also includes,

[0064] A driving member 53 is rotatably mounted on the fixing member 51. The driving member 53 has an internal tooth portion 531, and a half tooth portion 521 meshes with the internal tooth portion 531. The driving member 53 rotates through the half tooth portion 521 to drive the switching member 52 to rotate along the hinge point.

[0065] In this embodiment, the switch 52 has a half-tooth portion 521, and the switch assembly 5 also includes a drive 53. The drive 53 is rotatably mounted on the fixed member 51. The drive 53 has an internal tooth portion 531, and the half-tooth portion 521 meshes with the internal tooth portion 531. The drive 53 rotates through the half-tooth portion 521 to drive the switch 52 to rotate along the hinge point. The drive 53 is an internal gear, and the internal tooth portion 531 of the internal gear meshes with the half-tooth portion 521 on the drive 53. When the drive 53 is rotated, the drive 53 will drive the switch 52 to rotate in the same direction, thereby realizing the opening or closing of the second through hole 511. Rotating the drive 53 from the outside controls the connection or closing of the second through hole 511 and the feed port 105, making the feeding control more convenient.

[0066] Furthermore, the tank body 1 also has a first discharge port 106; and further includes,

[0067] Impeller 6 is rotatably disposed within the first through hole 103, and the impeller 6 rotates radially around the first through hole 103.

[0068] A drive shaft 7 is rotatably mounted on the tank body 1, and one end of the drive shaft 7 is connected to the impeller 6.

[0069] A wheel body 8 is disposed at the other end of the transmission shaft 7. The wheel body 8 cooperates with the driving component 53, and the rotation of the transmission shaft 7 drives the driving component 53 to rotate.

[0070] In this embodiment, the tank body 1 also has a first discharge port 106; it also includes an impeller 6, a drive shaft 7, and a wheel body 8. The impeller 6 is rotatably disposed in the first through hole 103 and rotates radially around the first through hole 103. The drive shaft 7 is rotatably disposed on the tank body 1, with one end of the drive shaft 7 connected to the impeller 6 and the wheel body 8 disposed at the other end of the drive shaft 7. The wheel body 8 cooperates with the drive member 53. The rotation of the drive shaft 7 causes the drive member 53 to rotate. During operation, when the gas in the tank body 1 is sucked out, the gas in the collection chamber 101 flows into the gas collection space 4, thereby driving the impeller 6 to rotate. The rotation of the impeller 6 will drive the drive shaft 53 to rotate. Shaft 7 rotates, and wheel 8 can be a gear or a pulley. Wheel 8 rotates to engage with the external part of drive component 53, driving drive component 53 to rotate, thereby connecting the second through hole 511 with the feed port 105, thus feeding material into tank 1. When material needs to be discharged, sliding component 3 moves in the opposite direction, sending air from gas collection space 4 into tank 1, thereby causing impeller 6 to flip. Through drive shaft 7 and wheel 8, drive component 53 flips, disconnecting the second through hole 511 from feed port 105. Impeller 6 can be used to adjust the rate of material discharge and feeding inside tank 1 while collecting gas inside the tank.

[0071] Furthermore, the tank 1 also has a second discharge port 107; the separation device 2 includes,

[0072] Separation shaft 201, which is rotatably mounted on the tank body 1.

[0073] The mesh cylinder 202 is disposed on the separation shaft 201. The discharge end of the feed inlet 105 is located at the feed end of the mesh cylinder 202, and the discharge end of the mesh cylinder 202 is located at the discharge end of the second discharge outlet 107.

[0074] In this embodiment, the tank 1 also has a second discharge port 107; the separation device 2 includes a separation shaft 201 and a screen cylinder 202. The separation shaft 201 is rotatably mounted on the tank 1, and the screen cylinder 202 is mounted on the separation shaft 201. The discharge end of the inlet 105 is located at the inlet end of the screen cylinder 202, and the discharge end of the screen cylinder 202 is located at the discharge end of the second discharge port 107. The coal slurry enters the screen cylinder 202 from the inlet 105. The coal slurry is located between the rotating shaft and the screen cylinder 202. The screen cylinder 202 rotates with the separation shaft 201. The screen cylinder 202 is inclined, and the vertical height of the inlet end of the screen cylinder 202 is higher than the discharge end. When the screen cylinder 202 rotates, the coal and water in the coal slurry are thrown out, while larger impurities fall from the screen cylinder 202 into the second discharge port 107, thereby achieving separation. By rotating the screen, the gas in the coal slurry can be released, making it easy to collect and process.

[0075] Furthermore, the separation device 2 also includes,

[0076] A baffle 203 is disposed on the tank body 1, and the baffle 203 is located vertically above the mesh cylinder 202.

[0077] Scraper 204, there are several scrapers 204, all of which are arranged on the separation shaft 201. The scrapers 204 are arranged along the axial direction of the separation shaft 201 and are in contact with the baffle 203.

[0078] In this embodiment, the separation device 2 further includes a baffle 203 and a scraper 204. The baffle 203 is disposed on the tank body 1 and is located vertically above the mesh cylinder 202. There are several scrapers 204, all of which are disposed on the separation shaft 201. The scrapers 204 are disposed along the axial direction of the separation shaft 201 and are in contact with the baffle 203. During operation, the baffle 203 is disposed inside the tank body 1 and can intercept the coal sludge thrown out above the mesh cylinder 202, preventing the coal sludge from being thrown into the buffer chamber 102 and thus affecting gas processing. The scraper 204 is disposed on the shaft and passes through the mesh cylinder 202. The scraper 204 is in contact with the inner side of the baffle 203. As the scraper 204 rotates with the rotating shaft, it can scrape off the coal sludge on the baffle 203 to prevent coal sludge from accumulating and affecting use.

[0079] Furthermore, it also includes,

[0080] A stirring shaft 9 is rotatably mounted on the tank body 1.

[0081] The stirring blade 10 is disposed on the stirring shaft 9.

[0082] A drive motor 11 is mounted on the tank body 1, and the output end of the drive motor 11 is connected to the stirring shaft 9.

[0083] In this embodiment, the system also includes a stirring shaft 9, stirring blades 10, and a drive motor 11. The stirring shaft 9 is rotatably mounted on the tank body 1, the stirring blades 10 are mounted on the stirring shaft 9, and the drive motor 11 is mounted on the tank body 1. The output end of the drive motor 11 is connected to the stirring shaft 9. During operation, the drive motor 11 drives the stirring shaft 9 to rotate, and the stirring shaft 9 drives the stirring blades 10 to rotate, thereby stirring the coal slurry at the bottom of the tank body 1. This not only prevents the coal slurry from settling and affecting the discharge, but also releases the residual coal gas in the coal slurry, allowing the coal gas to be collected and treated more completely, and reducing the amount of residual coal gas in the coal slurry.

[0084] A coal slime collection and treatment process includes the following steps:

[0085] S1. Use a cleaning machine to collect the coal slime and transport it to the coal slime collection system described in any one of claims 1 to 8;

[0086] S2. In the coal slime collection system, stones in the coal slime are separated and coal gas during transportation is collected;

[0087] S3. Use a filter press to separate the solids and liquids in the coal slime after separation in S2;

[0088] S4. Collect and store the solids separated in S3 as raw materials for coal bricks, and use the liquid separated in S3 for the preparation of water gas.

[0089] In this embodiment, the cleaning machine can collect underground coal slime. The collected coal slime, mixed with impurities, enters the coal slime collection system for separation, allowing larger particles to be screened out. During the screening process, coal gas can also be collected in tank 1. The screened coal slime is transported to a filter press to press out the water, thereby drying the coal material so that it can be used as fuel. The dried coal slime can be used as raw material for coal bricks or honeycomb briquettes. The liquid pressed out by the filter press contains coal residue and can be used to produce water gas, thus making full use of the coal slime.

[0090] Furthermore, the gas separated from S2 is dried and used as blast furnace fuel.

[0091] In this embodiment, the collected gas is dried in a dryer and can be used as fuel for the blast furnace, thereby saving raw materials and reducing the occurrence of accidents during the coal slime treatment process.

[0092] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
