Description

Technical Field

[0001] The present application relates to the technical field of chemical production equipment, and in particular to a drum slicing system. Background Art

[0002] In the production process of some chemical products (such as m-toluic acid, melting point 108-112°C), it is usually necessary to cool the molten material discharged from the discharge port of the reaction device (such as a reactor) after the reaction is completed, and then package it. However, since these chemical products will quickly form blocks once the temperature drops below the melting point, it is difficult to package them, especially when they are required to be packaged in powder form, the blocks must be crushed. If the block materials are crushed mechanically, not only will the processing steps be increased, but it will also consume a lot of time, resulting in low production efficiency.

[0003] Therefore, some companies use drum slicers to scrape these materials after cooling to overcome the disadvantages of directly cooling them into blocks and then crushing them. However, a large amount of fine material dust will be generated during the scraping process. These dusts are light and easily suspended in the air. If not handled, they will cause pollution to the working environment and affect the health of operators. Therefore, the dust generated during the scraping process needs to be treated. The existing treatment method is to extract the dust generated during the scraping process through negative pressure, and use dry dust removal methods such as bag filtration to treat the dust. However, since these dust particles are fine, they will adhere to the surface and gaps of the filter bag, making it difficult to recover the dust. Utility Model Content

[0035] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application is clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work also fall within the scope of protection of the present application.

[0036] like Figure 1 As shown, the present application provides a drum slicing system, comprising a slicing machine 1, an absorption tower 2 and an induced draft fan 3 connected in series in sequence;

[0037] The absorption tower 2 includes an air distribution pipe 22 vertically arranged at the lower part of a spray layer 21 arranged at the upper part of the tower, and a packing layer 23 is also arranged between the spray layer 21 and the air distribution pipe 22; a drain port 201 and a circulation port 202 are arranged at the bottom of the absorption tower 2; an overflow port 203 is opened on the side wall of the tower body between the circulation port 202 and the top of the air distribution pipe 22;

[0038] The circulation port 202 is connected to the input end of the circulation pump 4 and the solvent storage tank 41 respectively through the first three-way valve 100; the output end of the circulation pump 4 is connected to the spray layer 21 and the liquid storage tank 42 respectively through the second three-way valve 200;

[0039] The overflow port 203 is connected to the liquid storage tank 42 , the concentrator 43 and the liquid input end of the slicer 1 in sequence.

[0040] A drum slicing system, taking m-toluic acid (the intermediate of chlorantraniliprole) as an example, its working process is as follows:

[0041] When in use, the concentrator 43 evaporates and removes the solvent in the m-toluic acid to obtain liquid m-toluic acid. The liquid m-toluic acid is transferred to the slicer 1 for cooling and crystallization. The solid obtained by cooling and crystallization is transferred to a storage container for storage.

[0042] During the scraping process, fine m-toluic acid dust will be generated, which will not only lead to the deterioration of the working environment, but also cause the waste of m-toluic acid. Therefore, the dust generated during the scraping process needs to be absorbed and treated.

[0043] The induced draft fan 3 is turned on to exhaust air from the absorption tower 2 . At this time, the absorption tower 2 will be in a negative pressure state, and the dust generated during the scraping process of the slicer 1 will be sucked into the absorption tower 2 through the exhaust hood 17 .

[0044] The gas entering the absorption tower 2 enters the absorption tower 2 from the gas distribution pipe 22, moves from bottom to top, and contacts with the absorption liquid (such as toluene) sprayed by the spray layer 21, dissolving the dust in the absorption liquid and removing it. The gas after spraying and washing is sucked from the top of the tower by the induced draft fan 3 and discharged into the corresponding treatment device (such as an activated carbon adsorption tower or an incinerator) for treatment.

[0045] The absorbed liquid falls into the bottom of the absorption tower 2 and is drawn from the circulation port 202 via the circulation pump 4 to be supplied to the spray layer 21 for circulation washing.

[0046] When the absorption liquid concentration in the tower reaches a certain level, the second three-way valve 200 is adjusted to connect the circulation pump 4 and the liquid storage tank 42 and block the spray layer 21, and the absorption liquid in the tower is transferred to the liquid storage tank 42 for temporary storage, and then transferred to the concentrator 43 for concentration to carry out the next step of crystallization.

[0047] When the amount of absorption liquid in the tower is insufficient, the first three-way valve 100 can be adjusted to connect the circulation port 202 and the solvent storage tank 41 and block the circulation pump 4, and fresh solvent in the solvent storage tank 41 is added into the tower through the circulation port 202. When the amount of solvent added is too much, the excess solvent flows into the liquid storage tank 42 from the overflow port 203.

[0048] When the tower needs to be cleaned, the wastewater after cleaning can be discharged through the drain port 201 at the bottom of the tower.

[0049] The drum slicing system provided in the present application, by setting an absorption tower 2 and an induced draft fan connected in series with the slicer 1, sucks the dust generated during the scraping process of the slicer 1 into the tower, and recovers the dust by absorbing it with a solvent. This wet absorption method overcomes the disadvantage that the dust generated by the traditional slicer during scraping is not easy to be recycled by dry filtration methods such as filter bags.

[0050] Alternatively, if Figure 2 As shown, the air distribution pipe 22 is arranged through the bottom of the absorption tower 2, the lower end of the air distribution pipe 22 is connected to the slicer 1, and the upper end of the air distribution pipe 22 is installed with a wind cap 221.

[0051] In the present application, since the air distribution pipe 22 is arranged vertically, the absorption liquid will be sprayed on the top of the tower. If a wind cap is not installed, the absorption liquid will fall into the air distribution pipe 22 and affect the suction of dust from the slicer 1.

[0052] Alternatively, if Figure 3 As shown, the output end of the induced draft fan 3 is connected to the gas processing device 5 .

[0053] In the present application, part of the absorption liquid will be sucked away during the suction process of the induced draft fan 3. Most of these absorption liquids are organic solvents. If they are directly discharged, it will cause environmental pollution. Therefore, the gas treatment device 5 is set to harmlessly treat the solvent sucked by the induced draft fan 3 to reduce environmental pollution. The gas treatment device 5 is, for example, an activated carbon adsorption tower, an incinerator, and the like.

[0054] Alternatively, if Figure 4 to Figure 7 As shown, the slicer 1 includes a frame 12 for supporting a fixed shaft 11; the fixed shaft 11 is fixed to the frame 12 through a bracket 10;

[0055] The fixed shaft 11 passes through the axis of the roller 13, and the roller 13 is rotatably connected to the fixed shaft 11;

[0056] A cooling water tank 14 is provided in the drum 13 and is slidably connected to the drum 13. The cooling water tank 14 is arranged in an arc shape along the inner wall of the drum 13 and is fixed to the fixed shaft 11 through a connecting plate 15.

[0057] like Figure 5 As shown, a scraper device 16 is provided on the descending side of the rotating drum 13, and the scraper device 16 is in contact with the drum 13;

[0058] An exhaust hood 17 is provided above the drum 13, and the exhaust hood 17 is connected to the lower end of the air distribution pipe 22;

[0059] A liquid storage tank 121 mounted on the frame 12 is provided below the drum 13 .

[0060] In the present application, when the slicer 1 is in use, taking m-toluic acid as an example, the liquid m-toluic acid enters the slicer 1 and is temporarily stored in the liquid storage tank 121, which drives the roller 13 to rotate. The liquid m-toluic acid in the liquid storage tank 121 will adhere to the surface of the roller 13 and be cooled by the heat conducted by the cooling water tank 14 in the roller 13. The cooled liquid m-toluic acid forms solid crystals, adheres to the surface of the roller 13 and rotates with the rotation of the roller 13. When these solid crystals rotate with the roller 13 to the descending side of the roller 13, they are scraped off by the scraper on the scraper device 16 and collected in the receiving tray. When the scraped solids accumulate to a certain amount in the receiving tray, these solids are transferred to the storage container for storage.

[0061] Since the crystals on the surface of the drum 13 are scraped off by the scraping device 16, fine m-toluic acid dust is generated in the scraping process, which not only deteriorates the working environment but also causes waste of m-toluic acid. Therefore, the dust generated in the scraping process needs to be absorbed.

[0062] The induced draft fan 3 is turned on to exhaust air from the absorption tower 2 . At this time, the absorption tower 2 will be in a negative pressure state, and the dust generated during the scraping process of the slicer 1 will be sucked into the absorption tower 2 through the exhaust hood 17 .

[0063] The scraper device 16 includes a scraper and a receiving plate, which can be integrally formed and arranged. The scraper device 16 can be fixed on the frame 12 by a corresponding fixing device.

[0064] like Figure 7 As shown, the upper part of the cooling water tank 14 is respectively connected with a water inlet pipe 142 and a water outlet pipe 143. The water inlet pipe 142 passes through the fixed shaft 11 and comes out from one end of the fixed shaft 11 close to the connection between the water inlet pipe 142 and the cooling water tank 14; the water outlet pipe 143 passes through the fixed shaft 11 and comes out from one end of the fixed shaft 11 close to the connection between the water outlet pipe 143 and the cooling water tank 14.

[0065] The cooling water enters the upper part of the cooling water tank 14 through the water inlet pipe 142, then flows from top to bottom, and finally is discharged from the water outlet pipe 143 through the space isolated by the baffle 144. The cooling water in the cooling water tank 14 flows from top to bottom, and the liquid meta-methylbenzoic acid on the drum rotates from bottom to top with the drum 13, and the two form a countercurrent heat exchange mode, which can fully utilize the cold source provided by the cooling water and fully crystallize the liquid meta-methylbenzoic acid.

[0066] Alternatively, if Figure 8 As shown, a baffle 144 is vertically arranged at one end of the cooling water tank 14 near the water outlet pipe 143; the upper end of the baffle 144 is fixed to the upper end surface of the cooling water tank 14, and the lower end of the baffle 144 is close to the lower end surface of the cooling water tank 14;

[0067] A plurality of L-shaped baffles 145 are horizontally arranged between the baffle 144 and the side surface of the other end of the cooling water tank 14 .

[0068] When the cooling water tank 14 in the present application is in use, cooling water enters from the upper part of the cooling water tank 14 through the water inlet pipe 142, then flows from top to bottom through the L-shaped baffle 145, and finally is discharged from the water outlet pipe 143 through the space isolated by the baffle 144. The cooling water in the cooling water tank 14 flows from top to bottom, and the liquid meta-methylbenzoic acid on the drum rotates from bottom to top with the drum 13, and the two form a countercurrent heat exchange mode, which can fully utilize the cold source provided by the cooling water and fully crystallize the liquid meta-methylbenzoic acid.

[0069] In the present application, the cooling water tank 14 is fixed on the fixed shaft 11 and does not rotate with the drum 13, and the cooling water tank 14 and the drum 13 are connected by sliding. Figure 7As shown, the cooling water tank 14 is a partially cylindrical shell structure, which can reduce the amount of cooling water used. In addition, in the present application, the cooling water and the cooled material are countercurrently conducted to exchange heat, which can improve the cooling effect and save the amount of cooling water used.

[0070] Optionally, the wrap angle of the cooling water tank 14 is 200-270°.

[0071] In the present application, the wrap angle of the cooling water tank 14 is 200-270 degrees, which can save cooling water. The vacant part of the cooling water tank 14 (i.e., the range not covered by the cooling water tank 14) is the position from the highest point of the drum 13 to the descending side of the rotation direction of the drum 13, and the scraper in the scraper device 16 contacts the outer surface of the drum 13 in the range not covered by the wrap angle of the cooling water tank 14.

[0072] One end surface of the drum 13 is connected to the motor 6 via a transmission device 131 ; the transmission device 131 on one end surface of the drum 13 is rotationally connected to the fixed shaft 11 .

[0073] In the present application, a transmission device 131 (such as a gear, a sprocket or a pulley) arranged on one end surface of the drum 13 is fixedly connected to the drum 13 and is rotationally connected to the fixed shaft 11. When the motor 6 is started, the motor 6 drives the transmission device 131 to rotate and thereby drives the drum 13 to rotate, that is, the transmission device 131 and the drum 13 rotate with the fixed shaft 11 as the center axis.

[0074] Optionally, the transmission device 131 is a pulley, a sprocket or a gear.

[0075] In the present application, the use of a pulley, a sprocket or a gear transmission has the effect of being easy to implement.

[0076] A drum slicing system, taking m-toluic acid (the intermediate of chlorantraniliprole) as an example, its working process is as follows:

[0077] When in use, the concentrator 43 evaporates and removes the solvent in the m-toluic acid to obtain liquid m-toluic acid. The liquid m-toluic acid is transferred to the slicer 1 for cooling and crystallization.

[0078] After the liquid m-methylbenzoic acid enters the slicer 1, it is temporarily stored in the liquid storage tank 121. At this time, the motor 6 is turned on to drive the roller 13 to rotate through the transmission device 131 (a pulley or sprocket or gear in this application). The liquid m-methylbenzoic acid in the liquid storage tank 121 will adhere to the surface of the roller 13 and be cooled by the heat conducted by the cooling water tank 14 in the roller 13. The cooled liquid m-methylbenzoic acid forms solid crystals, adheres to the surface of the roller 13 and rotates with the rotation of the roller 13. When these solid crystals rotate with the roller 13 to the descending side of the roller 13, they are scraped off by the scraper on the scraping device 16 and collected in the receiving tray. When the scraped solids accumulate to a certain amount in the receiving tray, these solids are transferred to the storage container for storage.

[0079] The cooling water enters the upper part of the cooling water tank 14 through the water inlet pipe 142, then flows from top to bottom through the L-shaped baffle 145, and finally is discharged from the water outlet pipe 143 through the space isolated by the baffle 144. The cooling water in the cooling water tank 14 flows from top to bottom, and the liquid meta-methylbenzoic acid on the drum rotates from bottom to top with the drum 13, and the two form a countercurrent heat exchange mode, which can fully utilize the cold source provided by the cooling water and fully crystallize the liquid meta-methylbenzoic acid.

[0080] Since the crystals on the surface of the drum 13 are scraped off by the scraping device 16, fine m-toluic acid dust is generated in the scraping process, which not only deteriorates the working environment but also causes waste of m-toluic acid. Therefore, the dust generated in the scraping process needs to be absorbed.

[0081] The induced draft fan 3 is turned on to exhaust air from the absorption tower 2 . At this time, the absorption tower 2 will be in a negative pressure state, and the dust generated during the scraping process of the slicer 1 will be sucked into the absorption tower 2 through the exhaust hood 17 .

[0082] The gas entering the absorption tower 2 is output from the wind cap 221 on the air distribution pipe 22, enters the absorption tower 2, moves from bottom to top, and contacts with the absorption liquid (such as toluene) sprayed by the spray layer 21, and the dust is dissolved in the absorption liquid and removed. The gas after spraying and washing is sucked from the top of the tower by the induced draft fan 3 and discharged into the gas treatment device 5 (such as an activated carbon adsorption tower or an incinerator) for treatment.

[0083] The absorbed liquid falls into the bottom of the absorption tower 2 and is drawn from the circulation port 202 via the circulation pump 4 to be supplied to the spray layer 21 for circulation washing.

[0084] When the absorption liquid concentration in the tower reaches a certain level, the second three-way valve 200 is adjusted to connect the circulation pump 4 and the liquid storage tank 42 and block the spray layer 21, and the absorption liquid in the tower is transferred to the liquid storage tank 42 for temporary storage, and then transferred to the concentrator 43 for concentration to carry out the next step of crystallization.

[0085] When the amount of absorption liquid in the tower is insufficient, the first three-way valve 100 can be adjusted to connect the circulation port 202 and the solvent storage tank 41 and block the circulation pump 4, and fresh solvent in the solvent storage tank 41 is added into the tower through the circulation port 202. When the amount of solvent added is too much, the excess solvent flows into the liquid storage tank 42 from the overflow port 203.

[0086] When the tower needs to be cleaned, the wastewater after cleaning can be discharged through the drain port 201 at the bottom of the tower.

[0087] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
