Description

Technical Field

[0001] The utility model relates to the technical field of tar residue treatment, in particular to a tar residue sealing and drying treatment device. Background Art

[0002] Tar residue contains a large amount of fixed carbon and volatiles, and has a high calorific value, making it a useful secondary energy source. However, its volatiles contain a considerable amount of polycyclic aromatic hydrocarbons (PAHs), which are carcinogenic to humans and animals. Benzo(α) pyrene (3,4-benzopyrene) in particular, severely pollutes the atmosphere and harms human health. Currently, tar residue is primarily transported to coal yards for blending with coking coal before being added to the furnace. However, due to its high viscosity, tar residue is prone to poor coal feeding during blending, resulting in reduced blending accuracy and affecting the stability of coke quality. The centralized storage of tar residue in coal yards affects the regional atmospheric quality and, during the coking coal transportation process, affects the environment of the entire conveying corridor, significantly impacting the health of on-site workers. Tar residue contains approximately 30-40% coal tar, which, when added to the furnace with coal, burns, resulting in coal tar losses, reducing chemical product returns and hindering storage and transportation.

[0003] The tar residue recovery process involves drying treatment. The treatment equipment is generally a centrifuge. Through centrifugal shaking, the coal tar in the tar residue is separated, and the tar residue is turned from wet to dry. However, the tar residue has extremely high viscosity. During centrifugal treatment, especially in the initial stage of treatment, the viscosity is the highest, and it is easy to stick to the inner wall of the centrifugal equipment, resulting in incomplete shaking and low coal tar removal rate.

[0004] Therefore, in order to solve the above problems, a device can be designed to clean the tar residue stuck on the centrifugal filter cartridge while centrifugally drying the tar residue, thereby reducing the sticking phenomenon during the centrifugal drying process and improving the drying efficiency.

The sensing component is used to detect the operating status of the cleaning component and feed back a signal to the secondary drive component. After the tar residue is sent into the centrifugal component, the opening of the outer cylinder 4 is closed, and then the secondary drive component is started to control the centrifugal component to rotate at high speed. The centrifugal force is used to throw the coal tar on the tar residue between the centrifugal component and the outer cylinder 4. At the same time, the secondary drive component drives the cleaning component to move inside the centrifugal component to clean up the tar residue stuck on the centrifugal component. The sensing component detects the operating status of the cleaning component and feeds back a signal to the secondary drive component for forward or reverse power output to realize the reciprocating motion of the cleaning component and the power output of the centrifugal component in different directions. While the cleaning component is moving, the exhaust component outputs air flow into the centrifugal component to purge the tar residue and accelerate the seepage and dripping of coal tar between the tar residues.

[0027] See also Figure 1-Figure 2 In this embodiment, the first-stage driving assembly includes a base 601 installed on the base 1, a No. 1 gear 602 movably connected to the base 601, and a No. 1 motor 603 installed on the base 601. A ring gear 604 is installed on the outer cylinder 4. The No. 1 gear 602 is engaged with the ring gear 604. The No. 1 gear 602 is fixedly connected to the output end of the No. 1 motor 603. The No. 1 motor 603 drives the No. 1 gear 602 to rotate. The No. 1 gear 602 transmits power to the ring gear 604 engaged therewith, prompting the outer cylinder 4 to rotate. After the tar residue is dried, the outer cylinder 4 can be slowly rotated to allow the internal coal tar to flow and be discharged in multiple directions. At the same time, the tar residue in the centrifugal assembly can be turned over to reduce the sticking caused by standing still.

[0028] See also Figures 1-4In this embodiment, the centrifugal assembly includes an inner cylinder 701 arranged in the outer cylinder 4, a linkage sleeve 702 fixedly connected to one end of the inner cylinder 701, and an inner gear sleeve 703 fixedly connected to the linkage sleeve 702. The central axis of the inner cylinder 701 overlaps with the central axis of the outer cylinder 4. The linkage sleeve 702 is movably connected to the outer cylinder 4.

The third gear 803 is connected to the second gear 802, and the second gear 802 is meshed with the inner gear sleeve 703. The second motor 801 is used to drive the second gear 802, the inner cylinder 701 and the third gear 803 to rotate. When the second motor 801 drives the second gear 802 to rotate, the second gear 802 transmits power to the inner gear sleeve 703 on the centrifugal assembly, which in turn drives the inner cylinder 701 to rotate at high speed. The centrifugal force swings the tar residue inside, causing the coal tar to be discharged. At the same time, the rotation of the third gear 803 also transmits power to the cleaning assembly.

[0029] See also Figure 1-Figure 2 and Figure 4-Figure 7In this embodiment, the cleaning assembly includes a screw 901 movably connected to the linkage sleeve 702, an external gear sleeve 902 fixedly connected to the screw 901, a screw sleeve 903 threadedly connected to the screw 901, a push rod 904 fixedly connected to the screw sleeve 903, a push plate 905 fixedly connected to the push rod 904, and a plug 906 fixedly connected to the push plate 905. The external gear sleeve 902 is engaged with the No. 3 gear 803. The No. 2 motor 801 is used to drive the external gear sleeve 902 and the screw 901 to rotate. The screw 901 is used to drive the screw sleeve 903 to move along its axis. The push plate 905 is located in the inner cylinder 701 and is used to scrape off the tar residue on the inner cylinder 701. The screw 901 is a hollow structure, and one end of the screw 901 toward the inner cylinder 701 is open. The plug 906 is used to open or close the opening. The exhaust component includes an airbag cover 1001 installed on the screw sleeve 903, an air outlet 1002 opened on the screw 901, and a blowing hole 1003 opened on the push plate 905. When the screw sleeve 903 moves toward the side of the inner cylinder 701, the airbag cover 1001 is compressed, and the air is discharged from the air outlet 1002 to the outer cylinder 4; when the screw sleeve 903 moves toward the side of the outer gear sleeve 902, the airbag cover 1001 extends, and the air in the outer cylinder 4 enters the airbag cover 1001 from the air outlet 1002. The sensing component includes a The tension sensor 1102 and one end of the spring 1101 are installed on the tension sensor 1102, and the other end of the spring 1101 is connected to the linkage sleeve 702. The tension sensor 1102 is used to detect the tension value of the spring 1101. When the tension sensor 1102 detects that the tension value of the spring 1101 reaches the threshold, the No. 2 motor 801 outputs power in the reverse direction, and the No. 3 gear 803 transmits the power to the outer gear sleeve 902. The rotation of the outer gear sleeve 902 causes the screw 901 to rotate synchronously. Through the thread transmission action, the screw sleeve 903 moves linearly along the screw 901, and the push rod 904 and the push plate 905 move together and extend out of the linkage sleeve 702. The push plate 905 While scraping off the tar residue stuck on the inner cylinder 701, the plug 906 moves away from the open end of the screw 901, and the airbag cover 1001 contracts under the pressure of the screw sleeve 903, expelling the internal air. The air flows through the air outlet 1002 and the blowing hole 1003, acting on the tar residue, accelerating the infiltration of coal tar and the drying of the tar residue. When the airbag cover 1001 is compressed to the limit, the tension sensor 1102 detects that the stress of the spring 1101 reaches the threshold, and outputs a signal to the No. 2 motor 801. The No. 2 motor 801 outputs power in the reverse direction to control the inner cylinder 701 and the linkage sleeve 702 to rotate in the reverse direction. At the same time, the screw sleeve 903 moves in the reverse direction along the screw 901 to reset.

[0030] During operation, the tar residue is introduced from the opening of the outer cylinder 4 and sent to the inner cylinder 701, then the openings of the inner cylinder 701 and the outer cylinder 4 are closed, and the second motor 801 in the secondary drive assembly is started. The second motor 801 controls the second gear 802 and the third gear 803 to rotate synchronously. The second gear 802 outputs power to the inner cylinder 701 through meshing with the inner gear sleeve 703. The inner cylinder 701 rotates at high speed in the outer cylinder 4, and the centrifugal force is used to rotate the inner cylinder 701. The action causes the coal tar on the tar residue to be continuously thrown out of the inner cylinder 701. At the same time, the power is output to the screw 901 through the meshing of the outer gear sleeve 902 and the third gear 803. As the screw 901 rotates, the screw sleeve 903 moves linearly along the screw 901 due to the thread transmission effect, pushing the push plate 905 to slide in the inner cylinder 701. The push plate 905 scrapes off the tar residue sticking to the inner wall of the inner cylinder 701. As the push plate 905 moves, the plug 905 06 Open the opening at the end of the screw 901, and the screw sleeve 903 compresses the airbag cover 1001 to contract. The air in the airbag cover 1001 enters the screw 901 along the air outlet 1002, and is finally blown from the open position of the screw 901 to the push plate 905, and is discharged into the inner cylinder 701 from the blowing hole 1003 on the push plate 905, acting on the tar residue, forcing the coal tar to accelerate the infiltration and discharge, and also has the effect of accelerating the drying of the tar residue. While moving, the screw sleeve 903 also has a compressing and stretching effect on the spring 1101, and at the same time produces a tension change. When the screw sleeve 903 moves to the end of the screw 901, the tension reaches the preset value, and the tension sensor 1102 sends a signal to the No. 2 motor 801. The No. 2 motor 801 outputs power in the reverse direction, controls the inner cylinder 701 to rotate in the reverse direction, and makes the screw sleeve 903 move in the reverse direction along the screw 901. According to the above process, the centrifugal drying and cleaning process is repeated.
