Description

Technical Field

[0001] This utility model relates to the field of reagent production reaction vessel technology, and in particular to a reaction vessel for the production of chemical reagents that can be quantitatively proportioned. Background Technology

[0002] Chemical reagents are chemical substances used in chemical laboratories, mainly for various chemical experimental operations such as scientific research, teaching, testing and synthesis. Therefore, reaction vessels are required in the production of chemical reagents.

[0003] A search revealed Chinese patent CN222019469U, which discloses a reaction vessel for the production of chemical reagents with quantitative proportioning capability. The vessel includes a tank body with a heating assembly fixedly mounted on its surface. A cover is bolted to the top of the tank body, and a mounting platform is fixedly connected to the top of the cover. This invention features an automatic cleaning function achieved through the coordination of an electric push rod, a moving ring, a ring spray pipe, a delivery valve pipe, and a brush sleeve. The water source pipe is first connected to the delivery valve pipe and the latter is opened, allowing water to enter and spray out from the ring spray pipe. Simultaneously, the electric push rod is activated, pushing the moving ring to move the ring spray pipe up and down for cleaning. Furthermore, during the movement of the moving ring, the brush sleeve on its surface scrapes away stubborn residues from the inner wall. This mechanism effectively cleans the inner wall of the device and removes stubborn residues, thus preventing bacterial growth that could affect subsequent reagent production.

[0004] The aforementioned patent has the following shortcomings in a reaction vessel for the production of chemical reagents that can be quantitatively proportioned: it is inconvenient to replace the brush sleeve. After cleaning, reagent residue will adhere to the brush sleeve. If it is not replaced, it will contaminate the reagent during subsequent reagent production. The difficulty in replacing the brush sleeve may increase maintenance time and affect production continuity and efficiency. Therefore, it is urgent to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a reaction vessel for the production of chemical reagents that allows for quantitative proportioning.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A reaction vessel for the production of quantitatively proportioned chemical reagents includes a reaction vessel body, a cover on top of the reaction vessel body, and the reaction vessel body and the cover are fastened together by bolts. Electric push rods are fixedly connected to the top of both ends of the cover. The output ends of the two electric push rods pass through the cover and are fixedly connected to the same mounting plate. Three positioning rods are fixedly connected to the top of both ends of the mounting plate. The three positioning rods at the same end are fitted with the same arc-shaped plate. The arc-shaped plate has three positioning grooves adapted to the positioning rods. A brush sleeve is fixedly connected to the outer wall of the arc-shaped plate. Two fixing plates are fixedly connected to the top of the arc-shaped plate. A limit rod is fixedly connected to one side of each fixing plate. A moving block is fitted onto the limit rod, and the limit rod is slidably connected to the moving block. A spring is fitted onto the limit rod. The two moving blocks at the same end are fixedly connected to the same trapezoidal baffle. A handle is fixedly connected to the top of the trapezoidal baffle. Due to the use of... The invention employs a positioning rod to position the curved plate, and a trapezoidal baffle placed on top of the curved plate to limit its movement. This technique restricts the lateral position of the curved plate when it is fitted onto the positioning rod, and restricts its longitudinal position by placing the trapezoidal baffle on top. As the mounting plate moves up and down, the curved plate moves synchronously with it. Removing the trapezoidal baffle from the top of the curved plate allows it to be removed from the positioning rod, enabling cleaning or replacement of the brush sleeve. This effectively solves the problem of inconvenient brush sleeve replacement mentioned in the background technology. After cleaning, reagent residue remains on the brush sleeve, which, if not replaced, will contaminate reagents during subsequent production. The difficulty in replacing the brush sleeve may increase maintenance time and affect production continuity and efficiency. This invention achieves the technical effect of easy disassembly and replacement of the brush sleeve, effectively shortening maintenance time, streamlining the production process, and improving overall production efficiency.

[0007] As a further embodiment of this utility model, the cover has two slots, and a sealing plate is fixedly connected to the top of the cover at the position of the slot.

[0008] As a further embodiment of this invention, a controller is fixedly connected to the outer wall of the reactor body.

[0009] As a further embodiment of this utility model, a mounting platform is fixedly connected to the top of the cover, a proportioning box is fixedly connected to the top of the mounting platform, a distribution valve group is fixedly connected to the output end of the proportioning box, a metering box is fixedly connected to the output end of the distribution valve group, a discharge valve is provided at the bottom of the metering box, the discharge valve passes through the cover, the output end of the discharge valve is located inside the reactor body, a stand is provided at both ends of the bottom of the metering box, a pressure sensor is fixedly connected to both ends of the bottom of the stand at the bottom of the metering box, and the bottom of the pressure sensor is fixedly connected to the top of the cover.

[0010] As a further embodiment of this utility model, a motor is fixedly connected to the top of the cover, a rotating shaft passes through the cover, the rotating shaft is rotatably connected to the cover, a stirrer is fixedly connected to the outer wall of the rotating shaft, and the output end of the motor is connected to the rotating shaft through a coupling.

[0011] As a further embodiment of this utility model, an annular tube is provided inside the reactor body, the annular tube is fixedly connected to a mounting plate, a nozzle is fixedly connected to the output end of the annular tube, the annular tube communicates with the nozzle, and a conveying valve pipe is fixedly connected to the input end of the annular tube, the conveying valve pipe passes through the cover.

[0012] The beneficial effects of this utility model are as follows: By employing a positioning rod to position the curved plate and a trapezoidal baffle to limit its movement at the top, the technical means of positioning the curved plate effectively limit its lateral position when it is fitted onto the positioning rod, and limit its longitudinal position when the trapezoidal baffle is placed at the top. As the mounting plate moves up and down, the curved plate moves synchronously with it. Removing the trapezoidal baffle from the top of the curved plate allows it to be removed from the positioning rod, enabling cleaning or replacement of the brush sleeve. This effectively solves the problems raised in the background technology, such as the inconvenience of brush sleeve replacement, the presence of reagent residue on the brush sleeve after cleaning, and the potential for reagent contamination during subsequent production if not replaced. The difficulty in replacing the brush sleeve could increase maintenance time and affect production continuity and efficiency. This technology facilitates easy disassembly and replacement of the brush sleeve, effectively shortening maintenance time, streamlining the production process, and improving overall production efficiency.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figure 1-6A reaction vessel for the production of chemical reagents with quantitative proportioning capability includes a reaction vessel body 1, a cover 2 on the top of the reaction vessel body 1, and the reaction vessel body 1 and the cover 2 are fastened together by bolts. A valve is provided at the discharge port at the bottom of the reaction vessel body 1. Electric push rods 3 are fixedly connected to the top of both ends of the cover 2. The output ends of the two electric push rods 3 pass through the cover 2 and are fixedly connected to the same mounting plate 4. Three positioning rods 5 are fixedly connected to the top of both ends of the mounting plate 4. The three positioning rods 5 at the same end are fitted with the same arc-shaped plate 6. The arc-shaped plate 6 has three positioning grooves 7 that are adapted to the positioning rods 5. A brush sleeve 8 is fixedly connected to the outer wall of the arc-shaped plate 6. Two fixing plates 9 are fixedly connected to the top of the arc-shaped plate 6. A limit rod 10 is fixedly connected to one side of the fixing plate 9. A moving block 11 is fitted on the limit rod 10. The limit rod 10 is slidably connected to the moving block 11. A spring 12 is fitted on the limit rod 10. The two moving blocks 11 at the same end are fixedly connected to the same trapezoidal baffle 13. The top of component 3 is fixedly connected to a handle 14. Due to the use of a positioning rod to position the arc-shaped plate and a trapezoidal baffle to limit its movement by blocking the top of the arc-shaped plate, the lateral position of the arc-shaped plate is restricted when it is fitted onto the positioning rod, and the longitudinal position is restricted by blocking the top of the arc-shaped plate. When the mounting plate moves up and down, the arc-shaped plate moves synchronously with it. Removing the trapezoidal baffle from the top of the arc-shaped plate allows it to be removed from the positioning rod, enabling cleaning or replacement of the brush sleeve. This effectively solves the problem mentioned in the background technology where brush sleeve replacement is inconvenient, and reagent residue remains on the brush sleeve after cleaning. If not replaced, this residue will contaminate the reagent during subsequent production, potentially increasing maintenance time and affecting production continuity and efficiency. This invention achieves the technical effect of easy disassembly and replacement of the brush sleeve, effectively shortening maintenance time, making the production process smoother, and improving overall production efficiency.

[0017] In this embodiment, two slots 15 are provided on the cover 2, and a sealing plate 16 is fixedly connected to the top of the cover 2 at the position of the slots 15.

[0018] In this embodiment, a controller 17 is fixedly connected to the outer wall of the reactor body 1.

[0019] In this embodiment, a mounting platform 18 is fixedly connected to the top of the cover 2, a mixing tank 19 is fixedly connected to the top of the mounting platform 18, a distribution valve group 20 is fixedly connected to the output end of the mixing tank 19, a metering box 21 is fixedly connected to the output end of the distribution valve group 20, a discharge valve 22 is provided at the bottom of the metering box 21, the discharge valve 22 passes through the cover 2, and the output end of the discharge valve 22 is located inside the reactor body 1. Both ends of the bottom of the metering box 21 are provided with legs, and both ends of the bottom of the legs at the bottom of the metering box 21 are fixedly connected with pressure sensors 23. The bottom of the pressure sensors 23 is fixedly connected to the top of the cover 2, and the pressure sensors 23 and the discharge valve 22 are electrically connected to the controller 17 through wires.

[0020] In this embodiment, a motor 24 is fixedly connected to the top of the cover 2, a rotating shaft 25 is passed through the cover 2, the rotating shaft 25 is rotatably connected to the cover 2, a stirrer 26 is fixedly connected to the outer wall of the rotating shaft 25, the output end of the motor 24 is connected to the rotating shaft 25 through a coupling, and the motor 24 is electrically connected to the controller 17 through a wire.

[0021] In this embodiment, an annular pipe 27 is provided inside the reactor body 1. The annular pipe 27 is fixedly connected to the mounting plate 4. The output end of the annular pipe 27 is fixedly connected to the nozzle 28. The annular pipe 27 and the nozzle 28 are connected. The input end of the annular pipe 27 is fixedly connected to the conveying valve pipe 29. The conveying valve pipe 29 passes through the cover 2. The input end of the cover 2 is connected to an external water supply device, and water is supplied through the external water supply device.

[0022] Working principle: When in use, an external power supply is used. Activating the three valves of the distribution valve group 20 discharges the raw materials from the mixing tank 19, which then enter the metering box 21. Upon entering the metering box 21, the pressure sensor 23 senses the appropriate weight and sends a signal to the controller 17 to close the valves on the distribution valve group 20. The discharge valve 22 then opens, injecting the raw materials from the metering box 21 into the reactor body 1, completing the metering process. The motor 24 is then started. The output of the motor 24 drives the coupling to rotate, which in turn drives the rotating shaft 25 to rotate, which in turn drives the agitator 26 to rotate. After the raw materials are stirred and mixed, and production is completed, the valve at the bottom of the reactor body 1 is opened to discharge the reagents. Then, the inner wall of the reactor body 1 is cleaned. The electric push rod 3 is activated, causing its output end to extend. This output end of the electric push rod 3 drives the mounting plate 4 to descend, which in turn causes the arc plate 6 to descend. The arc plate 6 then drives the brush sleeve 8 to descend, scraping and cleaning the inner wall of the reactor body 1. Water is injected into the delivery valve pipe 29 through an external water supply device, and the water is finally sprayed out through the nozzle 28, rinsing the inner wall of the reactor body 1. 8 and brush sleeve 8 move up and down continuously until the cleaning work is completed. Then, the screws on the sealing plate 16 can be unscrewed, the sealing plate 16 can be removed, and the handles 14 can be moved closer together. The handles 14 will drive the trapezoidal baffle 13 to move, and the trapezoidal baffle 13 will drive the moving block 11 to move along the limit rod 10. The moving block 11 will compress the spring 12, causing the spring 12 to contract, and the trapezoidal baffle 13 can be removed from the top of the arc plate 6. The arc plate 6 can then be removed from the positioning rod 5, and the arc plate 6 and brush sleeve 8 can be taken out through the slot 15 for cleaning or replacement. When replacing, place the arc plate 6 and brush sleeve 8 into the reactor body 1 through the sealing plate 16. The trapezoidal baffle 13 can be moved again, or the arc plate 6 can be used to press the inclined surface of the trapezoidal baffle 13. Position the arc plate 6 on the positioning rod 5. When the arc plate 6 moves past the trapezoidal baffle 13, the contracted spring 12 will extend, which will allow the moving block 11 to move back to the initial position. The moving block 11 will drive the trapezoidal baffle 13 to move. Move the trapezoidal baffle 13 to the top of the arc plate 6 to restrict the arc plate 6. The arc plate 6 and brush sleeve 8 can then be assembled.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
