Description

Technical Field

[0001] The invention relates to the technical field of coal slime processing, and in particular to an anti-adhesion coal slime mixing device. Background Art

[0002] Coal slime refers to a mixture of fine coal and water produced during the coal washing process. The treatment and utilization of coal slime is an important technical issue, because the reasonable treatment of coal slime can not only improve the utilization rate of coal resources, but also reduce environmental pollution. Coal slime can generally be used after being treated by a coal slime stirring device. However, due to the fine particle size and high water content of coal slime, it is easy to stick together. The existing coal slime stirring device is prone to blockage and low efficiency when stirring and mixing coal slime, which is inconvenient.

[0003] Therefore, an anti-adhesion coal slime mixing device has been developed which can effectively prevent the coal slime from adhering during the mixing process and improve the coal slime mixing efficiency and quality. Summary of the invention

[0004] In order to overcome the disadvantages of existing coal slime stirring devices, which are prone to blockage and low efficiency when stirring and mixing coal slime, and are relatively inconvenient, the present invention provides an anti-sticking coal slime mixing device that can effectively prevent coal slime from sticking during the mixing process, thereby improving the coal slime mixing efficiency and quality.

[0005] The technical solution is: an anti-sticking coal slime mixing device, including a supporting foot, a mixing barrel, a mixing mechanism and an anti-sticking mechanism. The upper part of the supporting foot is connected to the mixing barrel, and the mixing barrel is provided with a mixing mechanism capable of mixing coal slime. The mixing barrel is also provided with an anti-sticking mechanism capable of preventing coal slime from sticking.

[0006] As an improvement of the above solution, a feed pipe is provided on the upper side of the middle part of the mixing barrel, and a discharge pipe is provided on the lower side of the right part of the mixing barrel.

[0007] As an improvement on the above scheme, the mixing mechanism includes a dual-axis motor, a guide cover, a mixing arm and a baffle. The dual-axis motor is connected to the lower middle side of the mixing barrel, the guide cover is rotatably connected to the lower inner side of the mixing barrel, the guide cover is connected to the output shaft on the upper side of the dual-axis motor, the mixing arm is connected to the upper side of the guide cover, and the baffle is clamped on the lower right part of the mixing barrel. The dual-axis motor is started to drive the guide cover to rotate, so that the mixing arm rotates to stir and mix the coal slime and raw coal. The guide cover can guide the coal slime located in the middle of the mixing barrel to the surrounding area to avoid coal slime aggregation. When the coal slime mixing is completed, the baffle is removed to allow the coal slime to be discharged from the discharge pipe.

[0008] As an improvement of the above solution, the guide cover is conical.

[0009] As an improvement on the above scheme, the anti-sticking mechanism includes a coal slime feed hopper, a drive motor, a gear set, a crushing roller and a hot air blower. The upper left side of the mixing barrel is connected to the coal slime feed hopper, the upper front side of the coal slime feed hopper is connected to the drive motor, the upper part of the coal slime feed hopper is rotatably connected to left and right crushing rollers, a gear set is provided between the front sides of the crushing rollers, the output shaft of the drive motor is connected to the crushing roller on the right, and the lower left side of the coal slime feed hopper is connected to the hot air blower. Start the drive motor, and the crushing roller rotates to crush the coal slime through the meshing movement of the gear set. After the coal slime is crushed, it moves to the interception net, and the hot air blower is started to allow the hot air to pass through the interception net.

[0010] As an improvement of the above solution, an interception net is provided at the lower part of the coal slime feed hopper.

[0011] As an improvement of the above scheme, it also includes an impact mechanism, which includes a guide ring, a first sliding frame, an impact plate and a first spring. The guide ring is connected to the output shaft on the lower side of the double-axis motor, the front and rear parts of the mixing barrel are slidably connected to the first sliding frame, the upper side of the first sliding frame is connected to the impact plate, the first sliding frame is connected to the mixing barrel with a first spring, the first sliding frame is in contact with the guide ring, and when the double-axis motor is started, it drives the guide ring to rotate, so that the guide ring squeezes the first sliding frame, and the first sliding frame moves up and down under the action of the first spring, thereby causing the impact plate to move up and down in the mixing barrel.

[0012] As an improvement of the above scheme, a dispersion mechanism is also included, which includes a space cam, a second sliding frame, a guide plate and a guide sleeve. The front side of the left crushing roller is connected to the space cam, the upper left part of the coal slime feed hopper is rotatably connected to two front and rear guide plates, the upper left part of the coal slime feed hopper is connected to the guide sleeve, and the second sliding frame is slidably connected to the guide sleeve. The second sliding frame is in contact and cooperate with the space cam, and the guide plates are movably connected to the second sliding frame. When the crushing roller rotates, it drives the space cam to rotate, so that the second sliding frame moves back and forth on the guide sleeve, pushing the guide plate to rotate, so that the guide plate swings to guide the coal slime in the coal slime feed hopper.

[0013] As an improvement of the above scheme, a dredging mechanism is also included, which includes a rotating arm, a contact frame and a protrusion. The upper part of the coal slime feed hopper is rotatably connected to the rotating arm, the lower part of the rotating arm is connected to the contact frame, and the front side of the right crushing roller is connected to the protrusion, which is squeezed and fitted with the rotating arm. When the crushing roller rotates, it drives the protrusion to rotate, so that the protrusion squeezes the rotating arm to rotate, and then the contact frame knocks the coal slime feed hopper.

[0014] As an improvement of the above scheme, a guiding mechanism is also included, which includes a guiding arm, a guiding arm and a second spring. The front and rear sides of the upper part of the mixing arm are connected to the guiding arms, and the guiding arms are slidably connected to the guiding arms. Two upper and lower second springs are connected between the guiding arms and the connected guiding arms. When the guide cover rotates, the guide arm is driven to rotate. The guiding arm is always kept in contact with the inner wall of the mixing barrel through the force of the second spring, and the coal slime is gathered when the guide arm rotates.

[0015] The beneficial effects are as follows: 1. The present invention starts the driving motor and meshes the gear set to rotate the crushing roller to crush the coal slime. After the coal slime is crushed, it moves to the interception net and starts the hot air blower to pass the hot air through the interception net, thereby drying the coal slime, reducing the moisture carried in the coal slime and preventing adhesion.

[0016] 2. The present invention starts the dual-axis motor and drives the guide ring to rotate at the same time, so that the guide ring squeezes the first sliding frame, and the first sliding frame moves up and down under the action of the first spring, thereby causing the impact plate to move up and down in the mixing barrel, thereby achieving the effect of impacting the coal slime, improving the coal slime mixing efficiency, and reducing the adhesion of the coal slime.

[0017] 3. The present invention drives the space cam to rotate while the crushing roller rotates, so that the second sliding frame moves back and forth on the guide sleeve, and pushes the guide plate to rotate, so that the guide plate swings to guide the coal slime in the coal slime feed hopper, thereby achieving the effect of dispersing the coal slime and ensuring uniform drying of the coal slime.

[0018] 4. The present invention drives the protrusion to rotate while the crushing roller rotates, so that the protrusion squeezes the rotating arm to rotate, and then the contact frame knocks the coal slime feed hopper, thereby achieving the effect of clearing the coal slime feed hopper and avoiding blockage of the coal slime feed hopper.

[0019] 5. The present invention drives the guide arm to rotate while the guide cover rotates. The guide arm is always kept in contact with the inner wall of the mixing barrel through the force of the second spring. The coal slime is gathered when the guide arm rotates, thereby ensuring that the coal slime is mixed evenly and preventing the coal slime from adhering to the inner wall of the mixing barrel.

[0032] An anti-adhesion coal slime mixing device, such as Figure 1 and Figure 2 As shown, it includes a supporting foot 1, a mixing barrel 2, a mixing mechanism 3 and an anti-sticking mechanism 4. The upper part of the supporting foot 1 is connected to the mixing barrel 2, a feeding pipe is provided on the upper middle side of the mixing barrel 2, and a discharging pipe is provided on the lower right side of the mixing barrel 2 for easy feeding and discharging. The mixing barrel 2 is provided with a mixing mechanism 3, and the mixing barrel 2 is also provided with an anti-sticking mechanism 4.

[0033] like Figure 1-Figure 3As shown, the mixing mechanism 3 includes a dual-axis motor 31, a guide cover 32, a mixing arm 33 and a baffle 34. The dual-axis motor 31 is connected to the lower middle side of the mixing barrel 2, and the guide cover 32 is rotatably connected to the lower inner side of the mixing barrel 2. The guide cover 32 is conical to facilitate the dispersion of coal slime. The guide cover 32 is connected to the output shaft on the upper side of the dual-axis motor 31, and the mixing arm 33 is connected to the upper side of the guide cover 32. The baffle 34 is clamped on the lower right part of the mixing barrel 2.

[0034] like Figure 1 , Figure 4 and Figure 5 As shown, the anti-sticking mechanism 4 includes a coal slime feed hopper 41, a drive motor 42, a gear set 43, a crushing roller 44 and a hot air blower 45. The upper left side of the mixing barrel 2 is connected to the coal slime feed hopper 41, the upper front side of the coal slime feed hopper 41 is connected to the drive motor 42, the upper part of the coal slime feed hopper 41 is rotatably connected to two left and right crushing rollers 44, a gear set 43 is provided between the front sides of the crushing rollers 44, the output shaft of the drive motor 42 is connected to the crushing roller 44 on the right, the lower left side of the coal slime feed hopper 41 is connected to the hot air blower 45, and the lower part of the coal slime feed hopper 41 is provided with an interception net to facilitate air circulation.

[0035] When using the present invention, first place the support foot 1 in the coal slime mixing area, then add the raw coal into the mixing barrel 2 from the feed pipe, and add the coal slime into the mixing barrel 2 from the coal slime feed hopper 41. After the coal slime is poured into the coal slime feed hopper 41, start the drive motor 42, and mesh the gear set 43 to rotate the crushing roller 44 to crush the coal slime. After the coal slime is crushed, move it to the interception net, start the hot air blower 45, and let the hot air pass through the interception net, so as to dry the coal slime, reduce the moisture carried in the coal slime and prevent adhesion. After the coal slime enters the mixing barrel 2, start the dual-axis motor 31 to drive the guide cover 32 to rotate, so that the mixing arm 33 rotates to stir and mix the coal slime and the raw coal. The guide cover 32 can guide the coal slime located in the middle of the mixing barrel 2 to the surrounding area to avoid coal slime aggregation. When the coal slime is mixed, the baffle 34 is removed to discharge the coal slime from the discharge pipe, thereby completing the mixing of the coal slime.

[0036] like Figure 1 and Figure 6 As shown, it also includes an impact mechanism 5, which includes a guide ring 51, a first sliding frame 52, an impact plate 53 and a first spring 54.

[0038] like Figure 1 , Figure 7 and Figure 8 As shown, a dispersion mechanism 6 is also included, which includes a space cam 61, a second sliding frame 62, a guide plate 63 and a guide sleeve 64.

[0039] The dispersing mechanism 6 of the device can be used to disperse the coal slime. When the crushing roller 44 rotates, the spatial cam 61 is driven to rotate, so that the second sliding frame 62 moves back and forth on the guide sleeve 64, pushing the guide plate 63 to rotate, so that the guide plate 63 swings to guide the coal slime in the coal slime feeding hopper 41, thereby dispersing the coal slime and ensuring uniform drying of the coal slime.

The upper part of the coal slime feed hopper 41 is rotatably connected to the rotating arm 71, the lower part of the rotating arm 71 is connected to the contact frame 72, and the front side of the crushing roller 44 on the right is connected to the protrusion 73, which is squeezed and matched with the rotating arm 71.

[0041] By using the dredging mechanism 7 of the device, the coal slime feed hopper 41 can be dredged. When the crushing roller 44 rotates, the protrusion 73 is driven to rotate, so that the protrusion 73 squeezes the rotating arm 71 to rotate, and then the contact frame 72 knocks the coal slime feed hopper 41, thereby playing a role in dredging the coal slime feed hopper 41 and avoiding blockage of the coal slime feed hopper 41.

[0042] like Figure 1 , Figure 3 and Fig.10As shown, a guiding mechanism 8 is also included, and the guiding mechanism 8 includes a guiding arm 81, a guiding arm 82 and a second spring 83.

The guiding arm 82 is always kept in contact with the inner wall of the mixing barrel 2 through the force of the second spring 83. When the guiding arm 82 rotates, the coal slime is gathered, thereby ensuring that the coal slime is mixed evenly and preventing the coal slime from sticking to the inner wall of the mixing barrel 2.
