Description

Technical Field

[0001] The present invention relates to the technical field of coal mine solid-liquid separation, and particularly relates to a centrifugal coal slime water solid-liquid separator. Background Art

[0002] The centrifugal coal slime water solid-liquid separator is a key equipment in coal mining, mainly used for treating coal slime water suspensions containing particulate matters. Its working principle is based on the centrifugal sedimentation principle. By using the centrifugal force generated by the high-speed rotation of the drum, the solid particles in the suspension rapidly settle towards the drum wall and form a sediment layer, while the clarified liquid is discharged through the overflow port. After the sediment layer is formed on the inner wall of the drum, the spiral component inside the drum can be used to push and discharge the sediment layer.

[0003] During the above operation process, since the particulate matters in the coal slime water entering the drum are of different sizes, after some larger-sized particulate matters settle on the inner wall of the drum, it will increase the wear degree of the relative operation between the spiral component and the drum, resulting in a reduction in the service life of the equipment. Summary of the Invention

[0004] The purpose of the present invention is to provide a centrifugal coal slime water solid-liquid separator. Based on the co-rotating operation of the drum and the inner spiral cylinder at different speeds, combined with the transmission cooperation formed by the preliminary screening component, the conveying component and the drum, the large particle substances in the coal slime water can be filtered and removed and automatically conveyed before entering the inner spiral cylinder and the drum. And combined with the reciprocating swinging rotation action formed by the sieve plate, the cleaning component and the multi-purpose blowing component can efficiently perform automatic cleaning work on the conveyor belt during use, which can not only improve the service life of the drum and the inner spiral cylinder, but also perform automatic maintenance and cleaning work on the conveying component for processing large particle substances during the working process.

[0005] The purpose of the present invention is achieved by such a technical solution. A centrifugal coal slime water solid-liquid separator includes a chassis component, an outer drum component, an inner spiral pushing component, a conveying component, a preliminary screening component, a cleaning component and a multi-purpose blowing component. The outer drum component includes a drum, the inner spiral pushing component includes an inner spiral cylinder, the conveying component includes a conveyor belt, the preliminary screening component includes a sieve hopper, a guide chute and side holes, the cleaning component includes a cleaning brush roller, and the multi-purpose blowing component includes a telescopic air box;

[0006] The rotary drum and the inner spiral cylinder are coaxially and rotatably connected to the top end of the chassis assembly, and the inner spiral cylinder is located inside the rotary drum. The conveyor belt is located directly below the rotary drum. The sieve hopper and the material guiding chute are both installed on one side of the top end of the chassis assembly. A side hole is opened on one side of the sieve hopper. A sieve plate is rotatably connected inside the sieve hopper. One end of the sieve plate extends into the chute body of the material guiding chute from the side hole. The discharge end at the bottom of the sieve hopper is connected to the inside of the inner spiral cylinder without interfering with the rotation of the inner spiral cylinder. The discharge end of the material guiding chute is connected to the conveyor belt. An eccentric wheel is rotatably connected to the outer side surface of the sieve hopper. The outer end of the rotating shaft of the sieve plate is fixed with an outer connecting arm. The eccentric end of the eccentric wheel is slidably connected to the outer connecting arm. The center of the eccentric wheel is drivingly connected to the conveyor belt, and the conveyor belt is drivingly connected to the rotary drum;

[0007] The cleaning brush roller is rotatably connected to the inner lower end of the chassis assembly and is drivingly connected to the conveyor belt. The lower surface of the discharge end of the conveyor belt contacts and rubs against the bristles of the cleaning brush roller. An air blowing main pipe is also installed at the inner lower end of the chassis assembly. The air outlet end of the air blowing main pipe is directly opposite to the contact position between the cleaning brush roller and the conveyor belt. The telescopic air box is installed between the outer bottom surface of the sieve plate and the inner bottom end of the side hole, and the air outlet end of the telescopic air box is unidirectionally communicated with the air blowing main pipe.

[0008] The usage process of the technical solution of the present invention is as follows:

[0009] After starting the rotary drive connected to the rotary drum and the inner spiral cylinder, the rotary drum and the inner spiral cylinder can be driven to rotate in the same direction at different speeds;

[0010] Before the external coal slime water enters the inside of the inner spiral cylinder, it must first enter the inlet at the top end of the sieve hopper. While the rotary drum is rotating, it can drive the automatic rolling and conveying of the conveyor belt. The conveyor belt drives the rotation of the eccentric wheel through the transmission mechanism. The eccentric end of the eccentric wheel forms a sliding fit with the outer connecting arm, so that while the eccentric wheel is rotating, it drives the sieve plate to swing and rotate reciprocally within a certain range. Since through holes with apertures smaller than the large particle substances in the coal slime water are arranged in the main body of the sieve plate, when the sieve plate swings and rotates reciprocally, the large particle substances in the coal slime water are screened out into the chute of the material guiding chute and are conveyed by the conveyor belt to the subsequent drying process through the guiding of the material guiding chute;

[0011] The substances in the coal slime water smaller than the aperture of the through holes opened in the sieve plate will enter the rotating inner spiral cylinder from the bottom of the sieve hopper. Through holes are opened at the position where the main body of the inner spiral cylinder is directly opposite to the conical surface of the rotary drum, so that the screened coal slime water can enter the inside of the rotary drum from the inner spiral cylinder. Under the action of the centrifugal force generated by the rotation of the rotary drum, the coal slime water is immediately thrown onto the inner wall of the rotary drum. The strong centrifugal force generated by the high-speed rotating rotary drum will throw the coal slime particles with a density greater than that of water onto the inner wall of the rotary drum, forming a solid coal slime layer. The density of water is less than that of the coal slime particles, so a liquid layer will be formed on the inner side of the coal slime layer;

[0012] The guiding effect formed by the position of the conical surface of the drum will cause the coal slime layer with a larger density to move towards the small cone end of the drum, and the liquid layer with a smaller density to move towards the large cone end. Under the action of the co-rotation of the inner spiral cylinder and the drum at different speeds, the inner spiral cylinder will push the coal slime attached to the inner wall of the drum towards the small cone end of the drum, and the liquid layer with a smaller density will be discharged outwards in the direction opposite to the movement of the coal slime until the coal slime is discharged through the outlet at the small cone end of the drum to the subsequent drying process;

[0013] Moreover, in cooperation with the automatic rolling and feeding work of the conveyor belt, it will drive the automatic rotation of the cleaning brush roller. When the cleaning brush roller rotates, it can rotate in the direction opposite to the rolling direction of the lower surface of the conveyor belt, and automatically clean the large particle substances attached to the surface of the conveyor belt, so that the large particle substances attached to the surface of the conveyor belt can also enter the subsequent drying process;

[0014] When the sieve plate swings and rotates reciprocally within a certain range, it can also form repeated compression and release actions on the telescopic air box, forming the air supply of the telescopic air box to the main blowing pipe, and can blow air to the cleaning brush roller in the cleaning state.

[0015] By adopting the above technical solutions, the present invention can achieve the following beneficial effects:

[0016] (1) The present invention is based on a drum and an inner spiral cylinder that rotate in the same direction and at different speeds, and one end of the drum and the inner spiral cylinder is a conical structure that matches each other. Through holes are provided at the position where the main body of the inner spiral cylinder faces the conical surface of the drum, which can form the main centrifugal solid-liquid separation effect on the coal slurry water. And by adjusting the change of the rotation speed of the inner spiral cylinder itself, different speed differences of the inner spiral cylinder relative to the drum can be formed, realizing the adjustment of the discharging speed while the inner spiral cylinder continuously discharges materials;

[0017] (2) In order to prevent large particle substances in the coal slurry water from damaging the inner spiral cylinder and the drum, the present invention also provides a primary screening component at the top side of the chassis component, and the bottom outlet of the material guiding groove is communicated with the conveyor belt. Utilizing the transmission connection formed by the drum and the conveyor belt, and the transmission connection formed by the conveyor belt and the sieve plate, while the drum rotates, the sieve plate swings and rotates reciprocally synchronously, and the conveyor belt rolls and conveys synchronously. It can not only use the sieve plate to screen and filter the coal slurry water first, removing large particle substances entering the inner spiral cylinder and the drum, but also use the conveyor belt to automatically convey the screened large particle substances to the subsequent drying process;

[0018] (3) A telescopic air box is further provided between the outer bottom surface of the sieve plate and the inner bottom end of the side hole, and the telescopic air box is provided with a side gradient compression surface structure, that is, the compression amount of the outer side surface of the telescopic air box is larger, and the compression amount of the inner side surface of the telescopic air box is smaller. It can cooperate with the swing and rotation of the sieve plate to safely and reliably form the compression and release actions of the telescopic air box, supply air to the air blowing main pipe facing the cleaning brush roller, and cooperate with the conveyor belt to drive the rotation of the cleaning brush roller, so as to efficiently carry out the automatic cleaning work at the discharge end of the conveyor belt and eliminate the phenomenon of large particle substances adhering to the outer surface of the conveyor belt.

[0040] As Figures 1 - 16 shown, a centrifugal coal slime solid-liquid separator, the rotating drum 201 and the inner spiral cylinder 308 are coaxially and rotatably connected to the top end of the chassis assembly 1, and the inner spiral cylinder 308 is located inside the rotating drum 201. One end of the rotating drum 201 and the inner spiral cylinder 308 is a tapered structure that matches each other. The rotating drum 201 and the inner spiral cylinder 308 can rotate in the same direction at different speeds. The conveyor belt 504 is located directly below the rotating drum 201. The sieve hopper 601 and the feed guide trough 605 are both installed on one side of the top end of the chassis assembly 1. A side hole 612 is opened on one side of the sieve hopper 601. A sieve plate 611 is rotatably connected inside the sieve hopper 601. One end of the sieve plate 611 extends into the trough body of the feed guide trough 605 from the side hole 612. The discharge end at the bottom of the sieve hopper 601 is connected to the inside of the inner spiral cylinder 308 and does not interfere with the rotation of the inner spiral cylinder 308. The discharge end of the feed guide trough 605 is connected to the conveyor belt 504. An eccentric wheel 613 is rotatably connected to the outer side surface of the sieve hopper 601. The outer end of the rotating shaft of the sieve plate 611 is fixed with an outer connecting arm 615. The eccentric end of the eccentric wheel 613 is slidably connected to the outer connecting arm 615. The center of the eccentric wheel 613 is drivingly connected to the conveyor belt 504. The conveyor belt 504 is drivingly connected to the rotating drum 201. When the rotating drum 201 and the inner spiral cylinder 308 rotate in the same direction at different speeds, it can synchronously drive the sieve plate 611 to rotate reciprocally within a certain range, and the conveyor belt 504 to continuously roll and work, and the feed guide trough 605 does not interfere with the rotational movement of the sieve plate 611;

[0041] The cleaning brush roller 701 is rotatably connected to the inner lower end of the chassis assembly 1 and is drivingly connected to the conveyor belt 504. The lower surface of the discharge end of the conveyor belt 504 contacts and rubs against the bristles of the cleaning brush roller 701. An air blowing main pipe 805 is also installed at the inner lower end of the chassis assembly 1. The air outlet end of the air blowing main pipe 805 is facing the contact position between the cleaning brush roller 701 and the conveyor belt 504. A telescopic air box 801 is installed between the outer bottom surface of the sieve plate 611 and the inner bottom end of the side hole 612, and the air outlet end of the telescopic air box 801 is unidirectionally communicated with the air blowing main pipe 805;

[0042] The working principle is as follows:

[0043] This device is used for the rapid separation of solid and liquid in coal slime water and the screening of large particulate matter before separation;

[0044] After starting the rotary drive connected to the drum 201 and the inner spiral cylinder 308, it can drive the drum 201 and the inner spiral cylinder 308 to rotate in the same direction at different speeds, and the rotation speed of the inner spiral cylinder 308 itself can be adjusted independently to achieve different speed differences between the inner spiral cylinder 308 and the drum 201. The purpose is to adjust the discharge speed while the inner spiral cylinder 308 continuously discharges. The greater the speed difference between the inner spiral cylinder 308 and the drum 201, the faster the discharge speed;

[0045] Before the external coal slime water enters the interior of the inner spiral cylinder 308, it must first enter the inlet at the top of the sieve hopper 601. While the drum 201 rotates, it can drive the automatic rolling and conveying of the conveyor belt 504. The conveyor belt 504 drives the rotation of the eccentric wheel 613 through the transmission mechanism. The eccentric end of the eccentric wheel 613 forms a sliding fit with the outer connecting arm 615, which can drive the sieve plate 611 to reciprocate and rotate within a certain range while the eccentric wheel 613 rotates. Since through-holes with apertures smaller than the large particulate matter in the coal slime water are arranged in the main body of the sieve plate 611, a vibrating effect can be formed when the sieve plate 611 reciprocates and rotates, so that the large particulate matter in the coal slime water is screened into the trough of the guide trough 605 and is conveyed by the conveyor belt 504 to the subsequent drying process through the guidance of the guide trough 605;

[0046] The substances in the coal slime water smaller than the aperture of the through-holes opened in the sieve plate 611 will enter the rotating inner spiral cylinder 308 from the bottom of the sieve hopper 601 due to gravity. Through-holes are opened at the position where the main body of the inner spiral cylinder 308 faces the conical surface of the drum 201, so that the screened coal slime water can enter the interior of the drum 201 from the inner spiral cylinder 308. Under the action of the centrifugal force formed by the rotation of the drum 201, the coal slime water is immediately thrown onto the inner wall of the drum 201. The strong centrifugal force generated by the high-speed rotating drum 201 will throw the coal slime particles with a density greater than that of water onto the inner wall of the drum 201 to form a solid coal slime layer. The density of water is less than that of the coal slime particles, so a liquid layer will be formed on the inner side of the coal slime layer;

[0047] The guiding effect formed at the conical surface position of the drum 201 will cause the coal slime layer with a greater density to move towards the small conical end of the drum 201, and the liquid layer with a smaller density to move towards the large conical end. Under the action of the same-direction and different-speed rotation of the inner spiral cylinder 308 and the drum 201, the inner spiral cylinder 308 will push the coal slime attached to the inner wall of the drum 201 towards the small conical end of the drum 201, and the liquid layer with a smaller density will be discharged outward in the direction opposite to the movement of the coal slime until the coal slime is discharged through the outlet at the small conical end of the drum 201 to the subsequent drying process;

[0048] Moreover, in coordination with the automatic rolling feeding operation of the conveyor belt 504, it will drive the automatic rotation of the cleaning brush roller 701. Since the cleaning brush roller 701 is arranged on the lower surface of the discharge end of the conveyor belt 504, when the cleaning brush roller 701 rotates, it can maintain a rotation opposite to the rolling direction of the lower surface of the conveyor belt 504, and automatically clean the large particle substances attached to the surface of the conveyor belt 504, so that the large particle substances attached to the surface of the conveyor belt 504 can also enter the subsequent drying process;

[0049] When the sieve plate 611 swings and rotates reciprocally within a certain range, it can also form repeated compression and release actions on the telescopic air box 801, forming the air supply of the telescopic air box 801 to the main blowing pipe 805. Since the outlet end of the main blowing pipe 805 is facing the contact position between the cleaning brush roller 701 and the conveyor belt 504, it can blow air to the cleaning brush roller 701 in the cleaning state, which can improve the cleaning effect of the cleaning brush roller 701.

[0050] The specific structures of the chassis assembly 1, the outer drum assembly 2, and the inner spiral pushing assembly 3 are as Figure 2 、 Figure 3 、 Figure 4 and Figure 5 shown.

[0055] On the end face at the other end of the rotary drum 201, waste water outlet holes 208 are arranged in a distributed manner, and there is a certain clearance between the end face of the rotary drum 201 where the waste water outlet holes 208 are opened and the inner cavity walls of the bottom cover body 102 and the top cover body 103, which is used to realize the discharge of the liquid layer in the slime water;

[0056] On both sides of the outer wall of the rotary drum 201, external rotary sleeves 209 are fixedly connected. In the inner cavities of the bottom cover body 102 and the top cover body 103, clamping rotary seats 210 are fixedly installed.

The solid material discharge pipe 211 and the waste water discharge pipe 212 are both connected to the bottom end of the bottom cover body 102 and are both communicated with the cavity formed by the bottom cover body 102 and the top cover body 103;

[0057] Through the rotary connection formed by the external rotary sleeve 209 and the clamping rotary seat 210, an independent discharge cavity for coal slime particles can be formed for the solid material passing pipe 207, so that the coal slime particles pushed to the small cone end of the rotary drum 201 by the centrifugal force can be discharged from the solid material passing pipe 207 into the solid material discharge pipe 211;

[0062] The rotation speeds of the inner rotating shaft 301 and the inner spiral cylinder 308 can be adjusted through the transmission 303, so that different rotational speed differences are formed between the inner spiral cylinder 308 and the rotating drum 201;

[0063] In the position where the main body of the inner spiral cylinder 308 faces the conical surface of the rotating drum 201, a discharge pipe 312 is arranged and connected. Moreover, the feed pipe 311 communicates with the discharge pipe 312 through the inner cavity of the inner spiral cylinder 308, enabling the operation of external coal slime water to enter the conical surface position of the inner cavity of the rotating drum 201 from the feed pipe 311 and the discharge pipe 312.
