Description

Technical Field

[0001] The utility model relates to the technical field of chemical reagent auxiliary production, in particular to a dosing device for chemical reagent auxiliary production. Background Art

[0002] Chemical reagent additives need to be added, mixed and stirred during the production process. This step is an important link to ensure the quality and performance of the reagents. During the adding and mixing process, the proportions and mixing conditions of various raw materials need to be strictly controlled to ensure the stability and purity of the final product.

[0003] Most of the existing dosing devices for the production of chemical reagent additives directly add all the reaction drugs at one time from the dosing port. Since too much drug is added and accumulated in one place, it is easy to reduce the mixing efficiency of the chemical reagent additive raw materials and the reaction drugs, and then make the chemical reagent additive raw materials and drugs mixed unevenly, which greatly affects the quality of subsequent chemical reagent additive production. In view of this, we propose a dosing device for the production of chemical reagent additives to solve the above problems. Utility Model Content

Since too much drugs are added and accumulated in one place, the mixing efficiency of the chemical reagent additive raw materials and the reaction drugs will be reduced, which will lead to uneven mixing of the chemical reagent additive raw materials and the drugs, affecting the quality.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a dosing device for the production of chemical reagent additives, comprising a fixed cover, a drug delivery tube is fixedly installed on the inner wall of the fixed cover, an intermittent drug delivery component for controlling the drug to pass through the drug delivery tube is arranged inside the fixed cover, the intermittent drug delivery component comprises a sealing cover installed on the inner wall of the drug delivery tube, two limit blocks extending to the inner wall of the drug delivery tube are fixedly installed on the side wall of the sealing cover, a sliding rod is fixedly installed on the inner wall of the fixed cover, a lead screw is rotatably installed on the inner wall of the fixed cover and on one side of the sliding rod, a moving block with the other end slidably connected to the sliding rod is threadedly installed on the surface of the lead screw, a connecting rod is rotatably installed on the top of the moving block, a connecting block is installed on the bottom of the sealing cover, and the end of the connecting rod away from the moving block is rotatably connected to the connecting block, and a driving component for driving the lead screw to rotate is also arranged on the surface of the fixed cover.

[0006] Furthermore, the driving assembly includes a reciprocating motor fixedly mounted on the surface of the fixed cover, one end of the screw rod extends to the outside of the fixed cover, and the end of the screw rod extending to the outside of the fixed cover is fixed to the output end of the reciprocating motor.

[0007] Furthermore, the upper surface of the lower medicine tube is inclined, and the outer wall of the sealing cover is also inclined, and the size of the sealing cover is adapted to the inner wall of the lower medicine tube.

[0008] Furthermore, a plug rod is fixedly mounted on the bottom of the sealing cover, a slot matched with the plug rod is opened on the top of the connecting block, and the plug rod is fixed to the connecting block by bolts.

[0009] Furthermore, a sealing sleeve extending into the interior of the fixed cover is fixedly mounted on the exterior of the fixed cover, and the outer wall of the screw rod is rotatably connected to the inner wall of the sealing sleeve.

[0010] Furthermore, a fixing ring for pulling the sealing cover is fixedly installed on the top of the sealing cover, and two limiting grooves are provided on the inner wall of the lower medicine tube.

[0014] 1. The dosing device for the production of chemical reagent additives has a sealing cover arranged above the drug dispensing tube to block drug dispensing, and the moving block can be moved by driving the screw rod to rotate through the driving assembly. When the moving block moves to the middle of the screw rod, the sealing cover will be completely lifted up, so that the drug can be dispensed.

This reciprocating movement allows the drug to be intermittently mixed with the raw materials for the production of reagent additives, thereby providing time for the mixing of the raw materials for the production of reagent additives and the drug, improving the mixing efficiency, and further ensuring the quality of the later production of reagent additives.

[0015] 2. The dosing device for the production of chemical reagent additives has a plug rod and a slot.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 3 , Figure 4 and Figure 5 An intermittent drug delivery component for controlling the passage of drugs through the drug delivery tube 2 is arranged inside the fixed cover 1, and the intermittent drug delivery component includes a sealing cover 3 installed on the inner wall of the drug delivery tube 2, and two limit blocks 17 extending into the inner wall of the drug delivery tube 2 are fixedly installed on the side wall of the sealing cover 3, a sliding rod 6 is fixedly installed on the inner wall of the fixed cover 1, and a screw rod 5 is rotatably installed on the inner wall of the fixed cover 1 and located on one side of the sliding rod 6, and a moving block 7 with the other end slidably connected to the sliding rod 6 is threadedly installed on the surface of the screw rod 5, and a connecting rod 8 is rotatably installed on the top of the moving block 7, and a connecting block 9 is installed at the bottom of the sealing cover 3, and the end of the connecting rod 8 away from the moving block 7 is rotatably connected to the connecting block 9, and a driving component for driving the screw rod 5 to rotate is also arranged on the surface of the fixed cover 1.

[0026] Among them, a sealing cover 3 is set above the drug discharge tube 2 to block the drug discharge, and the driving assembly drives the screw 5 to rotate to move the moving block 7. When the moving block 7 moves to the middle of the screw 5, the sealing cover 3 will be completely lifted up, so that the drug can be discharged. When the moving block 7 moves to other positions of the screw 5, the sealing cover 3 is sealed on the inner wall of the drug discharge tube 2 to prevent the drug from falling. This reciprocating process allows the drug to be intermittently mixed with the raw materials for the production of reagents and auxiliary agents, thereby providing time for the mixing of the raw materials for the production of reagents and auxiliary agents and the drug, improving the mixing efficiency, and then ensuring the quality of the later production of reagents and auxiliary agents.

[0027] In this embodiment, the driving assembly includes a reciprocating motor 4 fixedly mounted on the surface of the fixed cover 1, one end of the screw rod 5 extends to the outside of the fixed cover 1, and the end of the screw rod 5 extending to the outside of the fixed cover 1 is fixed to the output end of the reciprocating motor 4.

[0028] See also Figure 3 and Figure 5 In this embodiment, the upper surface of the lower medicine tube 2 is inclined, and the outer wall of the sealing cover 3 is also inclined. The size of the sealing cover 3 is adapted to the inner wall of the lower medicine tube 2.

[0029] The upper surface of the medicine tube 2 is inclined and the outer wall of the sealing cover 3 is also inclined. When the sealing cover 3 is located above the medicine tube 2, it is convenient to put the medicine into the medicine.

[0030] See also Figure 6 In this embodiment, a plug rod 10 is fixedly installed at the bottom of the sealing cover 3, a slot 11 adapted to the plug rod 10 is opened at the top of the connecting block 9, the plug rod 10 is fixed to the connecting block 9 by bolts, and a sealing sleeve 13 extending into the interior is fixedly installed on the outside of the fixed cover 1, and the outer wall of the screw rod 5 is rotatably connected to the inner wall of the sealing sleeve 13.

[0031] Among them, through the provision of the insertion rod 10 and the slot 11, when the sealing cover 3 is not needed, the bolt can be removed with the sealing cover 3 open, thereby facilitating the removal of the sealing cover 3 and reinstalling it when needed, thereby facilitating the use of the device according to the drug administration situation.

[0032] In addition, the sealing sleeve 13 is provided to ensure the sealing of the medicine.

[0033] See also Figure 2 and Figure 5 In this embodiment, a fixing ring 12 for pulling the sealing cover 3 is fixedly installed on the top of the sealing cover 3, and two limiting grooves 18 are provided on the inner wall of the lower medicine tube 2. One end of the limiting block 17 extends to the inner wall of the lower medicine tube 2 and is slidably connected to the inner wall of the corresponding limiting groove 18, and the outer wall of the limiting block 17 is tightly fitted with the inner wall of the limiting groove 18.

[0034] The provision of the fixing ring 12 facilitates the staff to remove the sealing cover 3 when disassembling it.

[0035] In addition, the limiting groove 18 and the limiting block 17 are provided to limit the sealing cover 3 and make it more stable when moving up and down.

[0036] It is worth noting that even if the sealing cover 3 is fully lifted up, the limiting block 17 will not be separated from the limiting groove 18 .

[0037] See also Figure 1 In this embodiment, an observation window 16 for observing the amount of medicine is embedded on the surface of the fixed cover 1, a cover plate 14 is installed on the top of the fixed cover 1, and a positioning block 15 for positioning the fixed cover 1 is fixedly installed on the surface of the fixed cover 1, and a through hole is opened on the surface of the positioning block 15.

[0038] The observation window 16 is provided to facilitate the staff to observe the amount of medicine inside the fixed cover 1 .

[0039] In addition, the positioning block 15 and the through hole are provided to fix the drug delivery device.

[0040] When the present embodiment is in use, the cover plate 14 is opened, and the medicine to be dispensed is added into the interior of the fixed cover 1. At this time, the medicine is located above the sealing cover 3. Starting the reciprocating motor 4 drives the screw rod 5 to rotate reciprocatingly to make the moving block 7 move reciprocatingly. During the movement of the moving block 7, the sealing cover 3 will move up and down. When the moving block 7 is displaced to the middle of the screw rod 5, the sealing cover 3 is completely lifted up. At this time, the sealing cover 3 is located above the medicine dispensing tube 2, and the medicine above the sealing cover 3 will be dispensed through the medicine dispensing tube 2. When the moving block 7 is displaced to other places, the sealing cover 3 will slide on the inner wall of the medicine dispensing tube 2 to prevent the medicine from falling.
