Description

Technical Field

[0001] This utility model belongs to the field of reaction vessel technology, specifically relating to a reaction vessel with torque. Background Technology

[0002] A reaction vessel is a reaction device widely used in industries such as chemical, pharmaceutical, and food processing. It can withstand certain pressures and temperatures and is usually made of materials such as alloy steel, stainless steel, and arc enamel.

[0003] Existing reactors generally have a fixed torque. During operation, when the content of solids in the material is high or the viscosity is high, the stirring device may be damaged due to insufficient torque, which may cause overload of the drive unit and increase unnecessary maintenance costs. Utility Model Content

[0004] The purpose of this invention is to provide a simple and reasonably designed torque-driven reaction vessel in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A torque-driven reaction vessel includes a base. An electrical control box is mounted on the upper surface of one end of the base. A movable seat is mounted on the top of the electrical control box via an electric lifting device. A controller is fixedly mounted on the side wall of the movable seat. A servo motor is fixedly mounted on the movable seat above the controller. A stirring structure is mounted on one side of the servo motor via a linkage assembly. A vessel body is mounted on the base below the stirring structure. The linkage assembly includes a transmission box with one end fixed to the movable seat. Two frustum-shaped transmission rollers are arranged in the inner cavities at both ends of the transmission box. The two transmission rollers are arranged in opposite directions. The top ends of the transmission rollers are rotatably connected to the inner wall of the transmission box via a rotating shaft. The bottom ends of the two transmission rollers are respectively fixed to the output end of the servo motor and the top end of the stirring structure. A transmission belt is drivingly connected between the two transmission rollers. An adjustment structure for adjusting the height of the transmission belt is installed in the middle section of the transmission belt. A torque sensor for detecting the torque of the stirring structure is also installed on the transmission box. The adjustment structure and the torque sensor are both electrically connected to the controller.

[0007] As a further optimization of this utility model, the electric lifting device is a telescopic cylinder type lifting machine installed on the top of the electrical control box. The output end of the telescopic cylinder type lifting machine is fixed to the bottom of the movable seat. The controller and the servo motor are both electrically connected to the electrical control box through a cable chain.

[0008] As a further optimization of this utility model, the stirring structure includes a stirring rod with its top end fixed to the bottom end of one of the transmission rollers, the stirring rod passing through the transmission box and being rotatably connected to the transmission box, and a blade being fixedly connected to the bottom end of the stirring rod.

[0009] As a further optimization of this utility model, a sealing cover is fixedly sleeved on the middle section of the stirring rod, and multiple chucks are installed on the top of the sealing cover. A hopper, a sight light, a sight glass, a temperature transmitter, and a vacuum module are sequentially clamped and fixed on the multiple chucks.

[0010] As a further optimization of this utility model, the vacuum module includes a vacuum pipe with one end connected to the inside of the vessel body, and a pressure gauge and a control valve are installed at the connection between the vacuum pipe and the sealing cover.

[0011] As a further optimization of this utility model, multiple ear-shaped hanging locks are arranged in a ring on the outer wall of the top of the vessel body. The multiple ear-shaped hanging locks are rotatably connected to the outer wall of the vessel body through hinges. An air inlet pipe is connected to the side wall of the vessel body.

[0012] As a further optimization of this utility model, the bottom of the vessel body is integrally formed with a vessel bottom, the vessel bottom has a hemispherical structure, a discharge pipe is connected to the bottom end of the vessel bottom, and multiple support legs are fixedly connected to the bottom wall of the vessel bottom.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. A torque sensor is installed on the transmission box. The torque sensor is electrically connected to the controller to transmit the detection data to the controller in real time. When the torque sensor detects that the resistance to the rotation of the blade is large, the controller can control the electric telescopic extension. In conjunction with the connecting seat and adjusting roller, the transmission belt is pushed up to adjust the torque. This avoids the problem of the fixed torque in the existing reactor. When the content of solids in the material in the reactor is high or the viscosity is high, the servo motor is prone to overload damage due to the inability to adjust the torque.

[0015] 2. The blades are mounted on the transmission rollers inside the transmission box via the stirring shaft. The transmission box is connected to the top of the electrical control box via a telescopic cylinder lift. The sealing cover is installed on the middle section of the transmission rollers. When the material inside the vessel is discharged through the discharge pipe, the telescopic cylinder lift can be controlled to extend and drive the blades upward, opening the sealing cover and moving the blades above the vessel body. This makes it easier for staff to clean the blades inside the vessel, making it more convenient for users. Attached Figure Description

[0022] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0023] Example

[0024] like Figure 1 - Figure 5 As shown, a torque-driven reaction vessel includes a base 1 with casters 2 installed at the bottom of the base 1 to make it easier for users to move the entire device. An electrical control box 3 is installed on the upper surface of one end of the base 1. A movable seat is installed on the top of the electrical control box 3 via an electric lifting device. The electric lifting device is a telescopic cylinder type lifting machine 4 installed on the top of the electrical control box 3. The output end of the telescopic cylinder type lifting machine 4 is fixed to the bottom of the movable seat. When the telescopic cylinder type lifting machine 4 is started, the movable seat can be moved up and down by the telescopic cylinder type lifting machine 4.

[0025] A controller 5 is fixedly installed on the side wall of the movable seat, and a servo motor 6 is fixedly installed on the movable seat above the controller 5. Both the controller 5 and the servo motor 6 are electrically connected to the electrical control box 3 through a drag chain 23. The drag chain 23 is provided so that the servo motor 6 and the controller 5 can be powered when the controller 5 and the servo motor 6 move up and down with the movable seat.

[0026] A stirring structure is installed on one side of the servo motor 6 via a linkage assembly. The linkage assembly includes a transmission box 7 with one end fixed to the movable seat. Both ends of the transmission box 7 are equipped with a frustum-shaped transmission roller 701. The two transmission rollers 701 are arranged in opposite directions. The top of the transmission rollers 701 is rotatably connected to the inner wall of the transmission box 7 via a rotating shaft 702. The bottom ends of the two transmission rollers 701 are fixed to the output end of the servo motor 6 and the top of the stirring structure, respectively. A transmission belt 703 is connected between the two transmission rollers 701. An adjustment structure for adjusting the height of the transmission belt 703 is installed in the middle section of the transmission belt 703.

[0027] The adjustment structure is used to adjust the position of the transmission belt 703. The adjustment structure includes a connecting seat 704 located below the middle section of the transmission belt 703, and an adjusting roller 705 rotatably connected to the connecting seat 704. The middle section of the adjusting roller 705 has an annular groove, and the middle section of the transmission belt 703 is located in the annular groove. An electric telescopic rod 706 is located below the connecting seat 704 and its bottom end is fixedly connected to the transmission box 7. The output end of the electric telescopic rod 706 is fixed to the connecting seat 704. The electric telescopic rod 706 is electrically connected to the controller 5. When the electric telescopic rod 706 extends or retracts, it drives the transmission belt 703 to slide down along the height direction of the transmission roller 701 through the connecting seat 704 and the adjusting roller 705, thereby realizing the torque adjustment of the stirring structure.

[0028] The stirring structure includes a stirring rod fixed at the top and the bottom of one of the transmission rollers 701. The stirring rod passes through the transmission box 7 and is rotatably connected to the transmission box 7. A blade 9 is fixedly connected to the bottom of the stirring rod. When the servo motor 6 is started, the stirring rod can be driven to rotate through the transmission roller 701 and the transmission belt 703, thereby driving the blade 9 to rotate and stirring the material.

[0029] The transmission box 7 is also equipped with a torque sensor 8 for detecting the torque of the stirring rod. The torque sensor 8 is electrically connected to the controller 5 and is used to transmit the detection information to the controller 5 in real time.

[0030] A sealing cover 10 is fixedly fitted on the middle section of the stirring rod. Multiple ear-shaped locks 18 are distributed in a ring on the outer wall of the top of the vessel body 17. The multiple ear-shaped locks 18 are rotatably connected to the outer wall of the vessel body 17 through hinges. When in use, the sealing cover 10 can be used to cover the top opening of the vessel body 17, and then the ear-shaped locks 18 can be rotated to lock the sealing cover 10.

[0031] Multiple chucks 12 are installed on the top of the sealing cover 10. A hopper 11, a sight light 13, a sight glass 14, a temperature transmitter 15, and a vacuum module 16 are sequentially fixed on the multiple chucks 12. The vacuum module 16 includes a vacuum pipe with one end connected to the inside of the vessel body 17. A pressure gauge and a control valve are installed at the connection between the vacuum pipe and the sealing cover 10. An air inlet pipe 19 is connected to the side wall of the vessel body 17. When the material is easily reacted with oxygen in the air, the vacuum pipe can be connected to an external vacuum pump to extract the air from the vessel body 17 and introduce protective gas into the vessel body 17 through the air inlet pipe 19 to protect the material and prevent oxidation reaction during the stirring process.

[0032] The bottom of the vessel body 17 is integrally formed with a vessel bottom 20, which has a hemispherical structure. Multiple support legs 22 are fixedly connected to the bottom wall of the vessel bottom 20 to support the vessel body 17 to a suitable height. A discharge pipe 21 is connected to the bottom of the vessel bottom 20, and a discharge valve is installed at the connection between the discharge pipe 21 and the vessel bottom 20 to facilitate the discharge of the mixed material.

[0033] It should be noted that, in use, this torque-driven reactor involves feeding material into the reactor body 17 through the hopper 11. Then, the servo motor 6 is started, driving the transmission roller 701 mounted on its output end to rotate. This, in conjunction with the transmission belt 703 and the transmission roller 701 fixedly connected to the top of the stirring shaft, drives the impeller 9 to rotate at high speed, stirring and mixing the material inside the reactor body 17. After stirring is complete, the discharge valve mounted on the discharge pipe 21 is opened, discharging the material through the discharge pipe 21. A torque sensor 8 is installed on the transmission box 7 to detect the torque of the stirring shaft. The torque sensor 8 is connected to the control... The controller 5 is electrically connected to transmit the detection data to the controller 5 in real time. When the torque sensor 8 detects that the resistance to the rotation of the blade 9 is large, the controller 5 can control the electric telescopic rod 706 to extend. In conjunction with the connecting seat 704 and the adjusting roller 705, the transmission belt 703 is pushed, so that the transmission belt 703 moves up along the height direction of the transmission roller 701, thereby realizing the adjustment of torque. This avoids the problem of the fixed torque of the existing reactor. When the content of solids in the material in the reactor body 17 is high or the viscosity is high, the servo motor 8 is prone to overload damage due to the inability to adjust the torque.

[0034] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
