Description

Technical Field

[0001] The utility model belongs to the technical field of chemical equipment, and specifically relates to a 2,3-dichloropyridine condensation and slicing device. Background Art

[0002] 2,3-Dichloropyridine is an important organic synthesis intermediate, which is widely used in organic synthesis reactions, such as the preparation of catalysts and the synthesis of organic compounds. It can be widely used in the preparation of organic compounds such as pesticides, dyes, photosensitizers, and medicines. When preparing 2,3-dichloropyridine, the 2,3,6-trichloropyridine reduction method can be used. The preparation process requires a relatively low temperature. H2 is used as a reducing agent to reduce 2,3,6-trichloropyridine. During the reduction process, carbon is added dropwise. Alkaline reagents such as sodium chloride are used to increase the reaction rate, and precious metal catalysts such as platinum and palladium need to be added during the reaction process. The 2,3-dichloropyridine product obtained in the preparation process is liquid. Since the melting point of 2,3-dichloropyridine is 64-67°C, the 2,3-dichloropyridine crystallizes into a solid state when the temperature drops to room temperature. Therefore, in order to prevent 2,3-dichloropyridine from cooling into a solid in the storage device, the liquid 2,3-dichloropyridine needs to be processed into fragments in time to facilitate subsequent packaging, transportation and sales at room temperature.

[0003] A Chinese patent with publication number CN208824470U discloses a 2,3-dichloropyridine condensation slicing device, comprising a frame, a motor, a reduction mechanism, a rotating inner cylinder and a fixed outer cylinder; the fixed outer cylinder is fixedly mounted on the upper part of the frame, and the rotating inner cylinder is rotatably arranged in the fixed outer cylinder; the motor is connected to the rotating inner cylinder through the reduction mechanism, and the motor is used to drive the rotating inner cylinder to rotate in the fixed outer cylinder; a spiral scraper is arranged between the inner wall of the fixed outer cylinder and the outer wall of the rotating inner cylinder, the spiral scraper is relatively fixed to the fixed outer cylinder, a nozzle is installed on the inner wall of the fixed outer cylinder, and the gap between the inner hole of the spiral scraper and the outer wall of the rotating inner cylinder is less than 1 mm; a discharge port is arranged on the lower side of the fixed outer cylinder, and a cooling water inlet and a cooling water outlet are respectively arranged at both ends of the rotating inner cylinder.

[0004] Although the device in the above application cuts solid 2,3-dichloropyridine by a spiral scraper, it cannot ensure that the fragments of 2,3-dichloropyridine after cutting have the same shape and size. It may be necessary to classify them by size or weigh them before processing, which is not convenient for subsequent packaging and sales, and greatly increases the production cost.

[0005] In view of this, the present utility model is proposed. Utility Model Content

[0009] An L-shaped plate is fixed to the relative outer ends of the two tooth plates, and the two L-shaped plates are located above the barrel plate. A moving component is installed between the relative outer sides of the two L-shaped plates. The moving component is installed in the upper middle part of the support table, and the upper side of the barrel plate is slidably matched with a slice.

[0010] Optionally, a plurality of notches are provided on the upper side of the condensation placement plate, a plurality of barrels corresponding to the notches are installed on the lower side of the barrel plate, the barrels are made of hoses, and a condenser and a 2,3-dichloropyridine storage device located on one side of the condensation placement plate are respectively installed on the upper side of one end of the workbench, and the output ends of the condenser and the 2,3-dichloropyridine storage device are respectively fixedly connected to the condensation placement plate and one end of the barrel plate.

[0011] By adopting the above technical solution, using the set condenser and 2,3-dichloropyridine storage, cooling water and liquid 2,3-dichloropyridine can be injected into the condensation placement plate and multiple barrels respectively, so that the cooling water covers the circumference of the multiple barrels in all directions, thereby quickly condensing and solidifying the liquid 2,3-dichloropyridine placed in the multiple barrels, effectively improving the condensation efficiency of the liquid 2,3-dichloropyridine, and at the same time ensuring that the diameter of the solidified 2,3-dichloropyridine in each barrel is the same, preparing for subsequent slicing.

[0013] By adopting the above technical solution, the distance between the column and the sliding column can be changed by using a sliding column that is slidably matched with the middle part of the lower end of the column, so as to prepare for the next step of compacting the condensed and solidified 2,3-dichloropyridine or pushing the solid 2,3-dichloropyridine out of the barrel plate, and the two plates are connected more stably by using the attraction of two magnets, so as to better compact the condensed and solidified 2,3-dichloropyridine or push the solid 2,3-dichloropyridine out of the barrel plate.

[0015] By adopting the above technical solution, the first screw is used to make the first screw cooperate with the Z-shaped block thread and drive the two support columns to move downward, thereby driving the two sliding columns to extend out of the middle of the lower ends of the two columns, so that the two sliding columns drive the two plates to compact the condensed and solidified 2,3-dichloropyridine, thereby reducing the gap between the 2,3-dichloropyridine and effectively improving the density of 2,3-dichloropyridine. At the same time, the two sliding columns drive the two support columns to slide and cooperate with the middle of the opposite ends of the Z-shaped block, thereby synchronously changing the distance between the two plates, which can avoid collision between the barrel plate and the two plates, so that the barrel plate moves up and down more smoothly, preparing for the next step of the two plates to push the solid 2,3-dichloropyridine out of the barrel plate.

[0016] Optionally, a second screw is rotatably engaged in the middle part of one of the rectangular blocks, and the circumferential side of the second screw is threadedly engaged with the condensation placement plate.

[0017] By adopting the above technical solution, the first motor can be used to drive the second screw to rotate, so that the second screw cooperates with the thread of the condensation placement plate, thereby driving the condensation placement plate to move up and down on the inner side of the two rectangular blocks, which can drive the condensed and solidified 2,3-dichloropyridine to extend out of the interior of the multiple slots. At the same time, the second motor drives the gear to rotate, so that the gear drives the two L-shaped plates to move relative to each other synchronously, thereby changing the distance between the two L-shaped plates, preparing for the next step of the moving component driving the two L-shaped plates to push the condensed and solidified 2,3-dichloropyridine out of the barrel plate.

[0019] By adopting the above technical solution, the electric guide rail can be used to drive the slice to move horizontally on the upper side of the condensation placement plate, so that the solid 2,3-dichloropyridine can be cut quickly and evenly, so that the fragments of 2,3-dichloropyridine after cutting are the same size, thereby facilitating the subsequent packaging of the fragments of 2,3-dichloropyridine.

[0020] Optionally, a slideway is provided on the upper side of the other end of the workbench, and a collection box is slidably fitted in the slideway, and the collection box corresponds to the other side of the barrel plate.

[0021] By adopting the above technical solution, using the collection box that slides in the slideway, the fragments of 2,3-dichloropyridine after cutting can be quickly collected and stored, reducing the later manual workload and effectively improving the overall work efficiency.

[0023] 1. Liquid 2,3-dichloropyridine can be injected into the barrel plate through the barrel plate corresponding to the condensation placement plate that is slidably matched between the inner sides of the upper parts of the two rectangular blocks, so that the condensation placement plate condenses and solidifies the liquid 2,3-dichloropyridine, thereby converting it into solid 2,3-dichloropyridine. At the same time, it can ensure that the solid 2,3-dichloropyridine in the barrel plate has the same size, which is convenient for the next step of slicing to cut the solid 2,3-dichloropyridine.

[0024] 2. By setting a moving component between the relatively outer sides of the two L-shaped plates, the two L-shaped plates can be driven to move up and down synchronously, so as to better compact the condensed and solidified 2,3-dichloropyridine synchronously or push the solid 2,3-dichloropyridine out of the barrel plate synchronously, further ensuring that the solid 2,3-dichloropyridine in the barrel plate is of the same size. At the same time, the slices that slide on the upper side of the barrel plate can reciprocate to cut the pushed-out solid 2,3-dichloropyridine, thereby ensuring that the fragments of the 2,3-dichloropyridine after cutting have the same shape and thickness, thereby facilitating subsequent packaging and sales, effectively reducing production costs, and improving work efficiency.

DETAILED DESCRIPTION

[0035] The utility model is now described in further detail with reference to the accompanying drawings.

[0036] See also Figure 1-6As shown, in this embodiment, a 2,3-dichloropyridine condensation slicing device is provided, comprising: a workbench 1, rectangular blocks 2 are installed on opposite sides above the workbench 1, a condensation placement plate 3 located between the lower parts of the two rectangular blocks 2 is installed on the upper side of the workbench 1, and a barrel plate 4 corresponding to the condensation placement plate 3 is slidably matched between the inner sides of the upper parts of the two rectangular blocks 2, and liquid 2,3-dichloropyridine can be injected into the barrel plate 4, so that the condensation placement plate 3 condenses and solidifies the liquid 2,3-dichloropyridine, thereby converting it into solid 2,3-dichloropyridine, and at the same time, it can ensure that the solid 2,3-dichloropyridine in the barrel plate 4 has the same size, which is convenient for the next step of slicing 10 to cut the solid 2,3-dichloropyridine, and a support platform 5 located above the barrel plate 4 is installed on the upper side of the workbench 1, and a gear 6 is rotatably matched in the middle of the lower side of the support platform 5, and two tooth plates 7 arranged oppositely are slidably matched on the lower side of the support platform 5, and the gear 6 is located between the two tooth plates 7 and meshes with the two tooth plates 7;

[0037] L-shaped plates 8 are fixed to the relative outer ends of the two tooth plates 7. The two L-shaped plates 8 are located above the barrel plate 4. A moving component 9 is installed between the relative outer sides of the two L-shaped plates 8, which can drive the two L-shaped plates 8 to move up and down synchronously, so as to better compact the condensed and solidified 2,3-dichloropyridine synchronously or push the solid 2,3-dichloropyridine out of the barrel plate 4 synchronously, further ensuring that the solid 2,3-dichloropyridine in the barrel plate 4 is of the same size. The moving component 9 is installed in the upper middle part of the support table 5, and the upper side of the barrel plate 4 is slidably matched with a slicer 10, which can reciprocate and cut the pushed-out solid 2,3-dichloropyridine, thereby ensuring that the fragments of 2,3-dichloropyridine after cutting have the same shape and thickness, so as to facilitate subsequent packaging and sales, effectively reduce production costs, and improve work efficiency.

[0038] The working principle of the device is as follows: when it is necessary to cut the condensed 2,3-dichloropyridine, firstly, cooling water and liquid 2,3-dichloropyridine are injected into the condensation placement plate 3 and the barrel plate 4 respectively. At this time, the temperature of the condensation placement plate 3 is reduced, and the liquid 2,3-dichloropyridine in the barrel plate 4 can be condensed and solidified into solid 2,3-dichloropyridine. Then, the moving component 9 is started. At this time, the moving component 9 drives the two L-shaped plates 8 to press downward, so that the two L-shaped plates 8 are in contact with the upper side of the barrel plate 4 and compact the solid 2,3-dichloropyridine. After the compaction is completed, the gear 6 is rotated so that the gear 6 is meshed with the two tooth plates 7, thereby driving the two tooth plates 7 and the two L-shaped plates 8 to move away from each other, avoid the barrel plate 4, and then move upward. The barrel plate 4, at this time, the solid 2,3-dichloropyridine after compaction moves upward synchronously with the barrel plate 4, and then the gear 6 is rotated in the opposite direction, so that the gear 6 is engaged with the two tooth plates 7, so that the two tooth plates 7 drive the two L-shaped plates 8 to approach each other. At this time, the two L-shaped plates 8 are located directly below the barrel plate 4, and then the moving component 9 drives the two L-shaped plates 8 to move upward. At this time, the two L-shaped plates 8 squeeze the lower end of the barrel plate 4 upward, so as to push the solid 2,3-dichloropyridine after compaction out of the barrel plate 4, and then the slicer 10 is started, and the slicer 10 moves back and forth left and right on the upper side of the barrel plate 4 to cut the solid 2,3-dichloropyridine after compaction, thereby completing the cutting work of the condensed 2,3-dichloropyridine.

[0039] It should be noted that all electrical devices involved in this application can be powered by batteries or external power supplies.

[0040] like Figure 4 As shown, a plurality of slots 11 are provided on the upper side of the condensation placement plate 3 of the present embodiment, a plurality of barrels 12 corresponding to the plurality of slots 11 are installed on the lower side of the barrel plate 4, the barrel 12 is made of a hose, and a condenser 13 and a 2,3-dichloropyridine storage device 14 located on one side of the condensation placement plate 3 are respectively installed on the upper side of one end of the workbench 1, and the output ends of the condenser 13 and the 2,3-dichloropyridine storage device 14 are respectively fixedly connected to the condensation placement plate 3 and one end of the barrel plate 4.

[0041] When liquid 2,3-dichloropyridine needs to be converted into solid 2,3-dichloropyridine, the condenser 13 and the 2,3-dichloropyridine storage 14 are started simultaneously. At this time, the output ends of the condenser 13 and the 2,3-dichloropyridine storage 14 respectively put cooling water and liquid 2,3-dichloropyridine into the condensation placement plate 3 and the multiple barrels 12. After the addition is completed, the temperature of the condensation placement plate 3 is reduced, and the liquid 2,3-dichloropyridine in the multiple barrels 12 can be condensed and solidified into solid 2,3-dichloropyridine, thereby completing the conversion of liquid 2,3-dichloropyridine into solid 2,3-dichloropyridine.

[0042] like Figure 1 As shown, the L-shaped plate 8 of this embodiment includes a column 15 fixed to one end of the tooth plate 7, a slide column 16 slidingly matched in the middle of the lower end of the column 15, a plate 17 fixed to the lower end of the slide column 16, and a magnet fixed to one end of the plate 17. The two magnets attract each other, and the two plates 17 are located directly above the barrel plate 4; Figure 4 As shown, the moving assembly 9 of this embodiment includes a first screw rod 18 rotatably engaged with the middle part of the upper part of the support platform 5, a Z-shaped block 19 threadedly engaged with the peripheral side of the first screw rod 18, two support columns 20 respectively slidably engaged with the middle parts of the opposite ends of the Z-shaped block 19, and two openings 21 respectively opened at the opposite ends of the support platform 5. The support columns 20 are slidably engaged in the openings 21, and the lower ends of the two support columns 20 are respectively fixed to the peripheral sides of the two sliding columns 16; Figure 5 As shown, the middle of one rectangular block 2 of this embodiment is rotatably matched with a second screw 22, the peripheral side of the second screw 22 is threadedly matched with the condensation placement plate 3, the middle of the upper end of one rectangular block 2 is fixed to the first motor 23, the output end of the first motor 23 is fixed to one end of the second screw 22, the middle of the support platform 5 is fixed with a second motor 24, and the output end of the second motor 24 is fixed to the axial center of the gear 6. The first screw 18 can be driven by a rotary motor.

[0043] When solid 2,3-dichloropyridine needs to be compacted, the rotary motor is started first, and the rotary motor drives the first screw 18 to rotate, so that the first screw 18 and the Z-shaped block 19 are threadedly matched to drive the two support columns 20 to press downward, so that the two support columns 20 respectively drive the two slide columns 16 to extend out of the middle of the lower ends of the two columns 15, and then the two slide columns 16 drive the two plates 17 to press downward synchronously, so that the two plates 17 are in contact with the upper side of the barrel plate 4 to compact the solid 2,3-dichloropyridine.

[0044] When solid 2,3-dichloropyridine needs to be pushed out from multiple barrels 12, the second motor 24 is started first, and the output end of the second motor 24 drives the gear 6 to rotate, so that the gear 6 is meshed with the two tooth plates 7, thereby driving the two tooth plates 7 and the two L-shaped plates 8 to move away from each other. At this time, the two sliding columns 16 drive the two support columns 20 to extend out of the middle of the opposite ends of the Z-shaped block 19, and at the same time, the two support columns 20 slide in the two openings 21 to avoid the barrel plate 4, and then the first motor 23 is started, and the output end of the first motor 23 drives the second screw 22 to rotate, so that the second screw 22 is threadedly engaged with the barrel plate 4 and drives the barrel plate 4 to slide and fit on the inner side of the two rectangular blocks 2. At this time, the barrel plate 4 moves to the side away from the condensation placement plate 3, and at the same time, the solid 2,3-dichloropyridine after compaction moves upward synchronously with the barrel plate 4. Then the second motor 24 drives the gear 6 to rotate in the opposite direction, so that the gear 6 meshes with the two tooth plates 7 in the opposite direction, so that the two tooth plates 7 drive the two L-shaped plates 8 to approach each other. At this time, the two slide columns 16 drive the two support columns 20 to retract to the middle of the opposite ends of the Z-shaped block 19. At the same time, the two plate bodies 17 are located directly below the multiple barrels 12. Then the rotary motor drives the first screw 18 to rotate in the opposite direction, so that the first screw 18 and the Z-shaped block 19 are reversely threaded and drive the two support columns 20 to move upward. At this time, the two support columns 20 drive the two slide columns 16 and the two plate bodies 17 to move upward synchronously. At the same time, the two slide columns 16 retract to the middle of the lower ends of the two columns 15. At this time, the two plate bodies 17 squeeze the multiple barrels 12 upward and push the solid 2,3-dichloropyridine out of the multiple barrels 12, thereby completing the solid 2,3-dichloropyridine from the multiple barrels 12.

[0046] When solid 2,3-dichloropyridine needs to be cut, the electric guide rail 26 is started, and the output end of the electric guide rail 26 drives the slice 10 to move horizontally on the upper side of the barrel plate 4, and cuts the solid 2,3-dichloropyridine. When the slice 10 moves to the other end of the barrel plate 4, the slice 10 drops the fragments of the cut solid 2,3-dichloropyridine into the collection box 28 for collection and storage.
