Description

Technical Field

[0001] This utility model relates to the field of magnetic stirring technology, and in particular to a magnetic stirring tank. Background Technology

[0002] A magnetic stirring tank is a closed container that uses non-contact magnetic force to mix or react media inside the tank. Its core feature is the stirring method without mechanical seals, making it suitable for process scenarios with high requirements for sealing, cleanliness, or leak prevention.

[0003] When existing magnetic stirring tanks control the temperature of raw materials, they mostly heat or cool the raw materials from the outside. Heating or cooling only from the outside will result in a large temperature gradient inside the tank, with the raw material near the tank wall being at a higher or lower temperature, while the raw material in the central area changes temperature slowly, resulting in uneven temperature distribution. Utility Model Content

[0004] The purpose of this invention is to provide a magnetic stirring tank that facilitates uniform temperature control of raw materials, thereby solving the problem of inconvenient uniform temperature control of raw materials in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A magnetic stirring tank includes a tank body, a feed pipe fixedly connected to the upper end of the tank body, a magnetic stirrer fixedly connected to the side wall of the tank body, a chamber provided inside the side wall of the tank body, a heating wire fixedly connected inside the chamber, and a discharge pipe fixedly connected to the lower end of the tank body; a pipe fixedly disposed inside the tank body, a plurality of slots provided on the side wall of the middle section of the pipe, the slots communicating with the chamber; and a ring seat disposed on the inner wall of the tank body, a plate fixedly connected to the side wall of the ring seat, a scraper first fixedly connected to the lower end of the plate, and a scraper second fixedly connected to the upper end of the plate.

[0007] Preferably, the upper end of the feed pipe is fixedly connected to a top cover by bolts, and a temperature detector is fixedly connected through the inside of the top cover.

[0008] Preferably, a controller is fixedly connected to the side wall of the tank, and the controller is electrically connected to the magnetic stirrer, the heating wire and the temperature detector respectively.

[0009] Preferably, a support seat is fixedly connected to the side wall of the tank, a gear is rotatably connected inside the support seat, a motor is fixedly connected to the lower end of the support seat, and multiple tooth grooves are provided on the side wall of the ring seat, with the gear side wall cooperating with the tooth grooves.

[0010] Preferably, a protrusion is fixedly connected to the side wall of the tank, and an air pump is fixedly connected to the upper end of the protrusion. The output end of the air pump is connected to the interior of the chamber, and the air pump is electrically connected to the controller.

[0011] Preferably, filter screens are fixedly connected inside both ends of the pipe, and the filter screens are made of high-temperature resistant metal.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] 1. The tank sidewall is heated directly by heating wires, while the pipes are heated by hot air. The combination of these two heating methods can raise the internal temperature of the tank more quickly, shorten the heating time, and improve production efficiency. At the same time, heating the raw materials from both the outside and inside can achieve more uniform heating of the raw materials, avoid local overheating or undercooling, and improve product quality.

[0014] 2. Operators only need to remove the magnetic stirrer to remove the stirring end from the tank, making room for subsequent cleaning work and avoiding cleaning obstacles caused by the presence of the stirrer. This makes the cleaning preparation work simpler and more direct. Then, the motor output drives the gear to rotate, and the engagement of the gear and the tooth groove causes the ring seat to rotate, which in turn drives scraper one and scraper two to rotate for cleaning. This automated cleaning method reduces the tedious operation of manual cleaning and reduces the labor intensity of operators. Attached Figure Description

A seat 004 and a ring seat 004 are located on the inner wall of the tank 001. A plate 402 is fixedly connected to the side wall of the ring seat 004. A scraper 403 is fixedly connected to the lower end of the plate 402, and a scraper 404 is fixedly connected to the upper end of the plate 402. The stirring end of the magnetic stirrer 104 is located inside the tank 001. The operator feeds the raw materials into the tank 001 through the feed pipe 101. Then, the magnetic stirrer 104 operates, magnetically stirring the raw materials inside the tank 001 through its stirring end. When the temperature inside the tank 001 is low... Heating wire 107 is activated, heating the side wall of tank 001 from the outside of the raw material. Simultaneously, airflow is supplied to chamber 106, which is heated by heating wire 107. The hot airflow flows to the top of chamber 106, then flows through multiple slots 301 into pipe 003, heating pipe 003 and heating the raw material from the inside through heat conduction. The heated airflow is discharged through the left and right ends of pipe 003. A manual valve is installed inside discharge pipe 105. The operator manually opens the discharge pipe 105 to allow the raw materials that have been mixed inside the tank 001 to be discharged through the discharge pipe 105. When it is necessary to clean the inside of the tank 001, the operator first removes the magnetic stirrer 104 so that the stirring end of the magnetic stirrer 104 is removed from the inside of the tank 001. Then, the ring seat 004 drives the scraper 1 403 and scraper 2 404 to rotate through the plate 402 respectively. The scraper 1 403 and scraper 2 404 scrape off the raw materials adhering to the inside of the tank 001.

[0023] The upper end of the feed pipe 101 is fixedly connected to the top cover 102 by bolts. A temperature detector 103 is fixedly connected through the inside of the top cover 102. The top cover 102 seals the inside of the feed pipe 101 to prevent foreign objects and impurities from entering the tank 001 through the feed pipe 101. The temperature detector 103 is an infrared detector. The infrared rays emitted by the temperature detector 103 are used to detect the temperature of the raw materials being stirred inside the tank 001.

[0024] A controller 108 is fixedly connected to the side wall of the tank 001. The controller 108 is electrically connected to the magnetic stirrer 104, the heating wire 107 and the temperature detector 103 respectively. When the operator turns on the controller 108, the controller 108 controls the magnetic stirrer 104 to start operating. The temperature detector 103 transmits the detected temperature data to the controller 108, and the controller 108 turns the heating wire 107 on and off.

[0025] A support seat 109 is fixedly connected to the side wall of the tank body 001. A gear 110 is rotatably connected inside the support seat 109. A motor 111 is fixedly connected to the lower end of the support seat 109. The side wall of the ring seat 004 is provided with multiple tooth grooves 401. The side wall of the gear 110 cooperates with the tooth grooves 401. The gear 110 is driven to rotate by the output end of the motor 111. The ring seat 004 rotates by the cooperation between the gear 110 and the tooth grooves 401. The gear 110 is a spur gear and the tooth grooves 401 are straight tooth grooves. The motor 111 is manually controlled by the operator to open and close.

[0026] A protrusion 002 is fixedly connected to the side wall of the tank 001. An air pump 201 is fixedly connected to the upper end of the protrusion 002. The output end of the air pump 201 is connected to the inside of the chamber 106. The air pump 201 is electrically connected to the controller 108. An activated carbon filter plate is fixedly connected inside the input end of the air pump 201. The controller 108 controls the air pump 201 to turn on and off. The air pump 201 delivers external airflow to the inside of the chamber 106.

[0027] Both ends of the pipe 003 are fixedly connected with filter screens 302. The filter screens 302 are made of high temperature resistant metal. The filter screens 302 prevent foreign objects and impurities from entering the pipe 003 through the left and right ends of the pipe 003.

[0028] In this invention, the operator feeds the raw material into the tank 001 through the feed pipe 101. Then, the operator fixes the top cover 102 to the upper end of the feed pipe 101 with bolts. The infrared rays emitted by the temperature detector 103 are directed into the tank 001. The operator edits the required temperature value of the raw material into the controller 108. The operator turns on the controller 108, which controls the magnetic stirrer 104 to start operating. The magnetic stirrer 104 stirs the raw material inside the tank 001 magnetically.

[0029] When the temperature detector 103 detects that the temperature inside the tank 001 is low, the controller 108 controls the heating wire 107 to start operating, heating the side wall of the tank 001 from the outside of the raw material. At the same time, the controller 108 controls the air pump 201 to operate, and the air pump 201 delivers external airflow into the chamber 106. The heating wire 107 heats the airflow, and the hot airflow flows to the top of the chamber 106. Then, the hot airflow flows through multiple slots 301 into the pipe 003, heating the pipe 003. The raw material is heated from the inside through heat conduction, and the heated airflow is discharged through the left and right ends of the pipe 003.

[0030] When the temperature detector 103 detects that the temperature inside the tank 001 is high, the controller 108 controls the heating wire 107 to turn off and controls the air pump 201 to operate. The air pump 201 delivers external airflow into the chamber 106 to cool the raw material from the outside. The airflow flows through multiple slots 301 into the pipe 003 to cool the pipe 003. The raw material is cooled from the inside through heat conduction. After cooling, the airflow is discharged through the left and right ends of the pipe 003.

[0031] When it is necessary to discharge the mixed raw materials from inside the tank 001, the operator manually opens the discharge pipe 105, so that the mixed raw materials inside the tank 001 can be discharged through the discharge pipe 105.

[0032] When it is necessary to clean the inside of the tank 001, the operator first removes the magnetic stirrer 104, so that the stirring end of the magnetic stirrer 104 is removed from the inside of the tank 001. The output end of the motor 111 drives the gear 110 to rotate. Then, through the cooperation between the gear 110 and the tooth groove 401, the ring seat 004 rotates. The ring seat 004 drives the scraper 1 403 and scraper 2 404 to rotate through the plate 402 respectively. The scraper 1 403 and scraper 2 404 scrape off the raw materials adhering to the inside of the tank 001.
