Description

Technical Field

[0001] This utility model relates to the field of filtration device technology, and in particular to a tar residue filtration device for coal tar production. Background Technology

[0002] Coal tar is a black or dark brown viscous liquid with a pungent odor, produced during the dry distillation of coal. It is a complex mixture of organic compounds, and filtration devices are needed to remove the tar residue during coal tar production. However, existing filtration devices generally suffer from the following problems:

[0003] When filtering coal tar, the coal tar is discharged into the filter tank and filtered by the filter plates. At this time, tar residue will remain on the top of the filter plates. Because it is difficult to discharge the tar residue, the filter plates are easily clogged, which reduces the filtration efficiency of the filtration device.

[0004] In summary, existing filtration devices struggle to remove tar residue, leading to tar clogging of the filter plates and reduced filtration efficiency. Therefore, we propose a tar residue filtration device for coal tar production. Utility Model Content

[0005] In order to solve the technical problems existing in the prior art, the present invention provides a pipe fitting placement device for water supply and drainage engineering construction.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a tar residue filtration device for coal tar production, comprising a frame, two mounting plates horizontally sliding through the frame, a filter tank fixedly mounted on one side of the two mounting plates that are close to each other, an inlet pipe connected to the center of the top of the filter tank, an outlet pipe connected to the center of the bottom of the filter tank, and an anti-clogging structure provided on the inner wall of the filter tank, the anti-clogging structure comprising a fixing ring fixedly mounted on the inner wall of the filter tank, a filter plate rotatably mounted on the inner wall of the fixing ring, the filter plate being fitted against the inner wall of the filter tank;

[0007] A drain pipe is installed on the outer periphery of the filter tank. An electric actuator is fixedly mounted on the outer wall of the drain pipe. A baffle is slidably installed inside the drain pipe and abuts against the top inner wall of the drain pipe. The output end of the electric actuator is fixedly connected to the baffle. The opening and closing state of the drain pipe is controlled by the vertical movement of the baffle.

[0008] Preferably, the filter plate has an umbrella-shaped structure.

[0009] Preferably, a first bevel gear is coaxially fixedly mounted on the lower end of the filter plate, and a transmission rod is horizontally rotatably installed inside the filter tank. One end of the transmission rod is coaxially fixedly mounted with a second bevel gear that meshes with the first bevel gear.

[0010] Preferably, a number of extension plates are fixedly mounted at equal intervals on the upper surface of the filter plate.

[0011] Preferably, a convex plate is fixedly mounted on the circumferential surface of the transmission rod, and an L-shaped rod is fixedly mounted on the frame relative to the position of the convex plate.

[0012] Preferably, a rotating wheel is rotatably mounted at one end of the short arm of the L-shaped rod, and the rotating wheel is in rolling contact with the convex plate.

[0013] Preferably, the line connecting the two mounting plates is perpendicular to the axis of the transmission rod, and a spring is also connected to the outer side of each mounting plate, extending toward and connecting to the frame.

[0014] Compared with the prior art, the present invention provides a tar residue filtration device for coal tar production, which has the following beneficial effects:

[0015] (1) In this utility model, when there is too much tar residue, the output end of the control electric actuator extends and the baffle moves downward along the drain pipe. At this time, the drain pipe is opened and the tar residue flows into the drain pipe along the surface of the filter plate and is then discharged by the drain pipe, which makes it convenient to clean the tar residue, prevents the tar residue from clogging the filter plate, and improves the filtration efficiency of the filter plate.

[0016] (2) The filter plate is set in an umbrella shape so that the tar residue slides down the surface of the filter plate after being filtered, so that the tar residue accumulates between the lower end of the filter plate and the filter tank. At this time, the upper end of the filter plate can still ensure the normal flow of coal tar, which improves the practicality of the filter plate.

[0017] (3) The output end of the motor will drive the transmission rod to rotate, the transmission rod will drive the second bevel gear to rotate, the second bevel gear will drive the first bevel gear to rotate, the first bevel gear will drive the filter plate to rotate along the surface of the fixed ring, and the rotation of the filter plate will cause the tar residue to be thrown off quickly due to the influence of centrifugal force and gravity, thereby accelerating the movement speed of the tar residue;

[0018] (4) During the operation of the motor, the transmission rod will drive the convex plate to rotate. After the convex plate comes into contact with the L-shaped rod, the L-shaped rod will squeeze the convex plate. The transmission rod will follow the convex plate and drive the filter can to move in the horizontal direction, thereby causing the filter can to vibrate and accelerate the rate of coal tar shedding.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0028] like Figures 1-6As shown, this utility model provides a tar residue filtration device for coal tar production, including a frame 1. Two mounting plates 2 slide horizontally through the frame 1. A filter tank 3 is fixedly mounted on one side of the two mounting plates 2 that are close to each other. An inlet pipe 4 is installed at the center of the top of the filter tank 3, and an outlet pipe 5 is installed at the center of the bottom of the filter tank 3. The inner wall of the filter tank 3 is provided with an anti-clogging structure 6. The anti-clogging structure 6 includes a fixing ring 601 fixedly mounted on the inner wall of the filter tank 3. A filter plate 602 is rotatably mounted on the inner wall of the fixing ring 601. The filter plate 602 is fitted against the inner wall of the filter tank 3. When filtering coal tar, the coal tar is introduced into the inlet pipe 4. The coal tar flows through the filter plate 602 inside the filter tank 3 and is filtered. Then, the filtered coal tar is discharged through the outlet pipe 5.

[0029] In practical applications, as the amount of filtered coal tar increases, a large amount of tar residue accumulates on the filter plate 602. This tar residue hinders the normal flow of coal tar through the filter plate 602, leading to a decrease in the filtration efficiency of the filter plate 602. To avoid this phenomenon, in this embodiment, a drain pipe 606 is connected and installed on the outer circumferential surface of the filter tank 3. An electric actuator 607 is fixedly mounted on the outer wall of the drain pipe 606, and a baffle 608 is slidably installed inside the drain pipe 606, with the baffle 608 abutting against the drain pipe 606. On the top inner wall of 06, the output end of the electric actuator 607 is fixedly connected to the baffle 608. When there is too much tar residue, the output end of the electric actuator 607 is extended, and the baffle 608 moves downward along the drain pipe 606, thereby opening the drain pipe 606. The tar residue will flow into the drain pipe 606 along the surface of the filter plate 602 and then be discharged by the drain pipe 606, which facilitates the cleaning of tar residue, prevents tar residue from clogging the filter plate 602, and improves the filtration efficiency of the filter plate 602.

[0030] In the above scheme, since the tar residue remains above the filter plate 602 during the filtration process, it is necessary to reduce the impact of the tar residue on the coal tar flowing through the filter plate 602. In this embodiment, the filter plate 602 is set into an umbrella-shaped structure, so that the tar residue slides down the surface of the filter plate 602 after being filtered, thereby accumulating between the lower end of the filter plate 602 and the filter tank 3. At this time, the upper end of the filter plate 602 can still ensure the normal flow of coal tar, which improves the practicality of the filter plate 602.

[0031] Furthermore, since coal tar is relatively viscous, the filtered tar residue moves slowly downwards along the surface of the filter plate 602. Therefore, it is necessary to accelerate the movement speed of the tar residue. Specifically, a motor 7 is fixedly mounted on the outer circumference of the filter tank 3. The output end of the motor 7 is fixedly connected to the transmission rod 604 via a coupling. A first bevel gear 603 is coaxially fixedly mounted on the lower end of the filter plate 602. The transmission rod 604 is horizontally rotatably mounted inside the filter tank 3. A second bevel gear 605, which meshes with the first bevel gear 603, is coaxially fixedly mounted on one end of the transmission rod 604. In use, when the motor 7 is turned on, the output end of the motor 7 will drive the transmission rod 604 to rotate. The transmission rod 604 will drive the second bevel gear 605 to rotate. The second bevel gear 605 will drive the first bevel gear 603 to rotate. The first bevel gear 603 will drive the filter plate 602 to rotate along the surface of the fixed ring 601. The rotation of the filter plate 602 will cause the tar residue to be thrown off quickly due to the influence of centrifugal force and gravity, thereby accelerating the movement speed of the tar residue.

[0032] In addition, in order to ensure that the filter plate 602 can drive the tar residue to rotate normally, in this embodiment, a number of extension plates 609 are fixedly installed at equal intervals on the upper surface of the filter plate 602. When the filter plate 602 rotates, it will drive the extension plates 609 to move, and the extension plates 609 will drive the tar residue to move, thereby ensuring that the filter plate 602 can accelerate the tar residue normally.

[0033] Because coal tar is quite viscous, some coal tar will be thrown onto the inner wall of the filter canister 3 when the filter plate 602 rotates. At this time, coal tar is easy to remain in the filter canister 3, making it difficult to discharge the coal tar completely. Therefore, it is necessary to reduce the amount of coal tar residue. In this embodiment, a convex plate 611 is fixedly mounted on the circumferential surface of the transmission rod 604, and an L-shaped rod 610 is fixedly mounted on the frame 1 relative to the position of the convex plate 611. During the operation of the motor 7, the transmission rod 604 will drive the convex plate 611 to rotate. After the convex plate 611 contacts the L-shaped rod 610, the L-shaped rod 610 will squeeze the convex plate 611. The transmission rod 604 will follow the convex plate 611 to drive the filter canister 3 to move in the horizontal direction, thereby causing the filter canister 3 to vibrate and accelerate the coal tar shedding speed.

[0034] Since the friction between the L-shaped rod 610 and the convex plate 611 is large after the convex plate 611 abuts against the surface of the L-shaped rod 610, it affects the normal rotation of the convex plate 611. Therefore, it is necessary to reduce the friction between the convex plate 611 and the L-shaped rod 610. Specifically, a rotating wheel 612 is rotatably installed at one end of the short arm of the L-shaped rod 610. When the convex plate 611 abuts against the arc surface of the rotating wheel 612, the convex plate 611 can still drive the filter tank 3 to vibrate, while the rotating wheel 612 can reduce the friction between the convex plate 611 and the L-shaped rod 610.

[0035] Since the filter canister 3 is difficult to quickly reset after moving with the cooperation of the convex plate 611 and the L-shaped rod 610, it is necessary to speed up the reset speed of the filter canister 3. In this embodiment, the line connecting the two mounting plates 2 is perpendicular to the axis of the transmission rod 604. A spring 613 is also connected to the outside of each mounting plate 2. The spring 613 extends toward and is connected to the frame 1. When the filter canister 3 moves, the filter canister 3 will drive the mounting plate 2 to move. At this time, the spring 613 will be stretched or compressed respectively. When the L-shaped rod 610 no longer squeezes the convex plate 611, the spring 613 will use its own elasticity to make the filter canister 3 quickly reset, thereby ensuring that the filter canister 3 can vibrate continuously.
