[0003] Current chemical engineering stirred tanks include a tank body, a stirring assembly for stirring and mixing chemical materials, and a drive device for driving the stirring assembly. Some stirred tanks are also equipped with a temperature control assembly to control the temperature of the reaction inside the stirred tank.

[0004] In existing chemical engineering stirred tanks, chemical materials are usually added to the stirred tank for mixing and reaction manually. Different substances (liquid and solid) are weighed and proportioned manually before being added to the stirred tank for stirring. Manual weighing and proportioning is prone to errors, and improper material ratios can lead to incomplete reactions or the generation of by-products, resulting in waste of chemical materials. Therefore, improvements are needed. Summary of the Invention

[0005] The purpose of this invention is to provide a chemical engineering mixing tank that facilitates the precise addition of liquid and solid chemical materials into the mixing tank according to a preset ratio, avoiding errors caused by manual weighing, saving time and effort, improving the accuracy of the mixing ratio, and preventing incomplete reactions or the generation of by-products due to improper material ratios.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a chemical engineering mixing tank, comprising a mixing tank body, a stepper motor mounted on the upper end face of the mixing tank body, the output end of the stepper motor penetrating through the upper end face of the mixing tank body and mounted with a stirring rod, a feeding mechanism mounted on the upper end face of the mixing tank body, the feeding mechanism comprising two feeding cylinders disposed on the upper end face of the mixing tank body, the two feeding cylinders being respectively used for feeding liquid chemical materials and solid chemical materials, a fixing ring fixedly mounted on the outer wall of the feeding cylinder, a support ring disposed below the fixing ring and disposed on the outer wall of the feeding cylinder, a weighing sensor being installed between the upper end face of the support ring and the bottom end face of the fixing ring, and a vibration motor being installed at the bottom of the outer wall of the feeding cylinder;

[0007] The upper end face of the mixing tank body has two through holes distributed to the left and right. The bottom of the two feed cylinders are connected to feed pipes that pass through the two through holes and extend into the interior of the mixing tank body. The ports of the through holes and the outer walls of the feed pipes are fitted with telescopic pleated sleeves.

[0008] In order to provide support for the support ring, in a preferred embodiment of the chemical engineering mixing tank of this utility model, a plurality of evenly distributed support rods are installed on the bottom end face of the support ring, and shock absorbers are installed between the bottom end face of the plurality of support rods and the upper end face of the mixing tank body.

[0009] To facilitate the addition of liquid chemical materials to the left feed cylinder, as a preferred embodiment of the chemical engineering mixing tank of this utility model, a support frame is installed on the outer wall of the support ring located on the left side, and a feed pipe with a solenoid valve is installed on the top of the support frame, with one end of the feed pipe extending directly above the left feed cylinder.

[0010] To facilitate the addition of solid chemical materials to the feed cylinder on the right, a preferred embodiment of this chemical engineering mixing tank is a screw conveyor located on the right side of the tank body, with the discharge port of the screw conveyor located at the port of the feed cylinder on the right.

[0015] When the two feed cylinders are feeding materials, the operation of two vibration motors causes the two feed cylinders to vibrate, increasing the feeding speed of the chemical materials in the two feed cylinders. This allows the set amount of chemical materials to be introduced into the mixing tank for stirring and mixing, enabling it to react fully.

Detailed Implementation

[0021] Please see Figures 1 to 4 A chemical engineering mixing tank includes a mixing tank body 1. A stepper motor 101 is installed on the upper end face of the mixing tank body 1. The output end of the stepper motor 101 passes through the upper end face of the mixing tank body 1 and is equipped with a stirring rod 102. A feeding mechanism 2 is installed on the upper end face of the mixing tank body 1. The feeding mechanism 2 includes two feeding cylinders 201 disposed on the upper end face of the mixing tank body 1. The two feeding cylinders 201 are used for feeding liquid chemical materials and solid chemical materials, respectively. A fixing ring 3 is fixedly installed on the outer wall of the feeding cylinder 201. A support ring 5 is disposed below the fixing ring 3 and disposed on the outer wall of the feeding cylinder 201. A weighing sensor 501 is installed between the upper end face of the support ring 5 and the bottom end face of the fixing ring 3. A vibration motor 6 is installed at the bottom of the outer wall of the feeding cylinder 201.

[0022] Two through holes 104 are provided on the upper end face of the mixing tank body 1. The bottom of the two feed cylinders 201 are connected to the discharge pipes 202 that pass through the two through holes 104 and extend into the interior of the mixing tank body 1. Telescopic pleated sleeves 105 are installed at the port of the through hole 104 and the outer wall of the discharge pipe 202.

[0023] In this embodiment: the amount of liquid and solid chemical materials is set on the controller. The liquid chemical materials are transported to the feed cylinder 201 on the left side by the feed pipe 801. At this time, the corresponding weighing sensor 501 can measure the amount of liquid chemical materials entering the feed cylinder 201. When the amount of liquid chemical materials in the feed cylinder 201 reaches the set amount, the controller closes the solenoid valve on the feed pipe 801, which can control the feed pipe 801 to stop feeding. The solid chemical materials are transported to the feed cylinder 201 on the right side by the screw conveyor 7. At this time, the corresponding weighing sensor 501 can measure the amount of solid chemical materials entering the feed cylinder 201. When the amount of solid chemical materials in the feed cylinder 201 reaches the set amount, the controller controls the screw conveyor 7 to stop transporting solid chemical materials.

[0024] Next, the controller opens the electric valves in the two feed pipes 202, allowing the weighed liquid and solid chemical materials to fall into the mixing tank body 1. At the same time, the two vibration motors 6 are started to run, causing the two feed cylinders 201 to vibrate and increase the feeding speed of the chemical materials in the two feed cylinders 201, so that the set amount of chemical materials can be introduced into the mixing tank body 1 for stirring and mixing so that it can react fully.

[0025] As a technical optimization of this utility model, a plurality of evenly distributed support rods 4 are installed on the bottom end face of the support ring 5, and shock absorbers 401 are installed between the bottom end face of the plurality of support rods 4 and the upper end face of the mixing tank body 1.

[0026] In this embodiment, the combination of multiple support rods 4 and multiple shock absorbers 401 can support the support ring 5, and the multiple shock absorbers 401 can buffer the vibrations received by the support rods 4.

[0027] As a technical optimization of this utility model, a support frame 8 is installed on the outer wall of the support ring 5 on the left side, and a feed pipe 801 with a solenoid valve is installed on the top of the support frame 8. One end of the feed pipe 801 extends to the top of the feed cylinder 201 on the left side.

[0028] In this embodiment: by setting up a feed pipe 801, it is convenient to introduce liquid chemical materials into the feed cylinder 201 located on the left side.

[0029] As a technical optimization of this utility model, a screw conveyor 7 is provided on the right side of the mixing tank body 1, and the discharge port of the screw conveyor 7 is located at the port of the right feed cylinder 201.

[0030] In this embodiment: by starting the screw conveyor 7, the solid chemical material is easily transported into the feed cylinder 201 located on the right.

[0031] As a technical optimization of this utility model, an electric valve is installed inside the feed pipe 202.

[0032] In this embodiment, a valve is provided to facilitate the control of opening and closing of the feed pipe 202.

[0033] As a technical optimization of this utility model, two scrapers 103 distributed on the left and right are installed at the bottom of the outer side wall of the stirring rod 102.

[0034] In this embodiment, a scraper 103 is provided to facilitate the removal of chemical materials remaining at the bottom of the mixing tank body 1.

[0035] Working principle: First, connect the device to an external power source and then to a controller. When using the device, connect the feed pipe 801 to the external liquid chemical material conveying pipe. Then, add solid chemical material into the feed hopper of the screw conveyor 7. Next, set the amounts of liquid and solid chemical material on the controller. When the liquid and solid chemical material are mixed, the controller opens the solenoid valve on the feed pipe 801, allowing the feed pipe 801 to convey the liquid chemical material into the feed cylinder 201 on the left. At this time, the corresponding weighing sensor 501 can measure the amount of liquid chemical material entering the feed cylinder 201. When the amount of liquid chemical material in the feed cylinder 201 reaches the set amount, the controller closes the solenoid valve on the feed pipe 801, which can control the feed pipe 801 to stop feeding.

[0036] During the weighing of liquid chemical materials, the controller can simultaneously control the screw conveyor 7 to transport solid chemical materials into the feed cylinder 201 located on the right. At this time, the corresponding weighing sensor 501 can measure the amount of solid chemical materials entering the feed cylinder 201. When the amount of solid chemical materials in the feed cylinder 201 reaches the set amount, the controller controls the screw conveyor 7 to stop transporting solid chemical materials.

[0037] Next, the controller opens the electric valves in the two feed pipes 202, allowing the weighed liquid and solid chemical materials to fall into the mixing tank body 1. At the same time, the two vibration motors 6 are started, causing the two feed cylinders 201 to vibrate and the two telescopic pleated sleeves 105 to extend and retract. As the feed cylinders 201 vibrate, the feeding speed of the chemical materials in the two feed cylinders 201 is increased. The stepper motor 101 is started, causing the stirring rod 102 to rotate and stir the chemical materials to ensure a full reaction. After the reaction is completed, the stirring rod 102 and the two scrapers 103 are rotated to facilitate the discharge of the reacted materials.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
