Description

Technical Field

[0001] This utility model relates to a reaction stirring vessel, and more particularly to a chemical heating reaction stirring vessel. Background Technology

[0002] A chemical processing reactor is an auxiliary device used in chemical processing to stir and heat chemical raw materials for reaction. It has been widely used in the field of reactors. When using a chemical processing reactor, the chemical raw materials are added into the stirring chamber through the feed port, and the stirring shaft is rotated through the discharge port to stir the chemical raw materials. At the same time, the heating equipment heats the heating liquid in the heating tank, and the heating liquid in the heating tank is pumped into the heating chamber through the lift pump to heat and react the chemical raw materials.

[0003] Chinese Patent Publication CN214183078U discloses a rapid heating and stirring chemical reaction vessel. By setting multiple heating rods to directly contact the reaction raw materials, the temperature of the reaction raw materials can be raised more quickly and evenly, reducing heating time and improving reaction efficiency. At the same time, this design also avoids the problems of local overheating or uneven heating that may occur in traditional heating methods, making the chemical reaction more stable and controllable.

[0004] The above-mentioned patented technical solution uses a heating rod to heat and stir the raw materials. However, since the heating rod is in direct contact with the raw materials for a long time, in some special chemical reactions, the surface is prone to scaling and coking, which leads to increased thermal resistance and damage. Utility Model Content

[0005] In view of this, the main objective of this utility model is to provide a chemical heating reaction stirring vessel to solve the problems of reduced heating efficiency, surface scaling and coking, and easy damage caused by prolonged direct contact between the heating rod and the reaction raw materials in the prior art.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: A chemical heating reaction stirring vessel includes a box body, a feed hopper, a discharge port, and a discharge valve. The feed hopper is disposed on the top of the box body, and its bottom is connected to the inside of the box body. The discharge port is disposed on the bottom surface of the box body, and the discharge valve is disposed on the discharge port. The vessel also includes a cleaning and heating mechanism, which includes a first power motor, a first fixed rod, a limiting cylinder, a heating rod, a worm gear, a second fixed rod, a second power motor, a worm, a first conductive ring, and a second conductive ring. The first power motor is disposed below the bottom surface of the box body. The upper surface of the first power motor is fixed to the bottom surface of the housing by two first fixing rods. The limiting cylinder is vertically installed inside the housing. The power output end of the first power motor passes through the bottom of the housing and is connected to the limiting cylinder. The heating rods have heating parts on both outer sides and connecting parts in the middle. Several heating rods are arranged horizontally from top to bottom and hinged to the side wall of the limiting cylinder. The worm gears are respectively installed on the connecting parts of the heating rods located inside the limiting cylinder. The top of the limiting cylinder is hinged to the top of the housing. The second power motor is located above the housing and is offsetly fixed to the top surface of the limiting cylinder by two second fixing rods. The upper end of the worm is connected to the power output end of the second power motor, and the lower end of the worm is hinged to the bottom surface of the corresponding limiting cylinder. The worm meshes with the worm wheel on the heating rod. Several first conductive rings are respectively installed on the connecting part of the corresponding heating rod inside the limiting cylinder, and the movable end of the first conductive ring is fixedly connected to the connecting part of the heating rod. The fixed end of the first conductive ring is fixed on the inner wall of the limiting cylinder. The second conductive ring is set on the top of the limiting cylinder, the movable end of the second conductive ring is fixed on the top of the limiting cylinder, and the fixed end of the second conductive ring is fixed on the box body around the limiting cylinder.

[0007] As a further technical solution, a water spray plate is also included, which is installed on the top wall of the tank.

[0008] As a further technical solution, a scraper is also included, wherein the scraper is horizontally arranged on the outer wall of the limiting cylinder of the corresponding heating rod, and the scraper head of each scraper presses against the outer arc surface of the corresponding heating rod.

[0009] As a further technical solution, a limiting block is also included, one end of which is fixedly connected to the inner wall of the limiting cylinder at the corresponding position, and the other end of which is connected to the fixed end of the first conductive ring.

[0010] The beneficial effects of adopting the above technical solution are as follows: A. The scraper can effectively clean the heating rods. Combined with the coordinated operation of the second power motor, worm gear, and turbine, it cleans scale and coke deposits on the surface of the heating rods while heating and stirring, preventing increased thermal resistance and damage to the heating rods due to scale and coke buildup. This effectively improves the service life and heating efficiency of the heating rods. Furthermore, regular water spraying from the spray plate further rinses the heating rods and the inner wall of the tank, thoroughly removing the cleaned-up dirt and maintaining the cleanliness of the equipment's interior, ensuring the smooth progress of the chemical reaction and the stability of product quality; B. With the cooperation of the first power motor, the limiting cylinder, and the heating rods, the heating rods can perform heating work while rotating. The first power motor drives the limiting cylinder to rotate, thereby rotating the heating rods and ensuring full contact between the reaction raw materials and the heating rods, further improving the uniformity and efficiency of heating, ensuring the normal operation of the entire stirring vessel, and meeting the strict requirements for heating reactions in chemical production.

Detailed Implementation

[0016] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0017] like Figures 1-5As shown, this utility model relates to a chemical heating reaction stirring vessel, which includes a housing 1, a feed hopper 2, a discharge port 3, and a discharge valve 4. The feed hopper 2 is located on the top of the housing 1, and its bottom is connected to the inside of the housing 1. The discharge port 3 is located on the bottom surface of the housing 1, and the discharge valve 4 is located on the discharge port 3. The vessel also includes a cleaning and heating mechanism, which includes a first power motor 5, a first fixing rod 6, a limiting cylinder 7, a heating rod 8, a worm gear 9, a second fixing rod 10, a second power motor 11, a worm gear 12, a first conductive ring 13, and a second conductive ring 14. The first power motor 5 is located below the bottom surface of the housing 1. The upper surface of the first power motor 5 is fixed to the bottom surface of the housing 1 by two first fixing rods 6. The limiting cylinder 7 is vertically arranged inside the housing 1. The power output end of the first power motor 5 passes through the bottom of the housing 1 and is connected to the limiting cylinder 7. The heating rods 8 have heating parts on both outer sides and connecting parts in the middle. Several heating rods 8 are arranged horizontally from top to bottom and hinged to the side wall of the limiting cylinder 7. The worm gears 9 are respectively arranged on the connecting parts of the heating rods 8 located inside the limiting cylinder 7. The top of the limiting cylinder 7 is hinged to the top of the housing 1. The second power motor 11 is located above the housing 1 and is offsetly fixed to the top surface of the limiting cylinder 7 by two second fixing rods 10. The upper end of the worm gear 12 is connected to the power output end of the second power motor 11, and the lower end of the worm gear 12 is hinged to the bottom surface of the corresponding limiting cylinder 7. The worm gear 12 meshes with the worm wheel 9 on the heating rod 8. Several first conductive rings 13 are respectively installed on the connecting part of the corresponding heating rod 8 inside the limiting cylinder 7, and the movable end of the first conductive ring 13 is fixedly connected to the connecting part of the heating rod 8. The fixed end of the first conductive ring 13 is fixed on the inner wall of the limiting cylinder 7. The second conductive ring 14 is set on the top of the limiting cylinder 7. The movable end of the second conductive ring 14 is fixed on the top of the limiting cylinder 7, and the fixed end of the second conductive ring 14 is fixed on the box 1 around the limiting cylinder 7.

[0018] As a further embodiment, a water spray plate 15 is also included, which is disposed on the inner top wall of the housing 1.

[0019] As a further embodiment, it also includes scraper rods 16, which are horizontally arranged on the outer wall of the limiting cylinder 7 of the corresponding heating rod 8, and the scraper head of each scraper rod 16 presses against the arc-shaped outer surface of the corresponding heating rod 8.

[0020] As a further embodiment, it also includes a limiting block 17, one end of which is fixedly connected to the inner wall of the limiting cylinder 7 at the corresponding position, and the other end of which is connected to the fixed end of the first conductive ring 13.

[0021] In use, the embodiments of this utility model first connect the first power motor 5, the second power motor 11, the first conductive ring 13, the second conductive ring 14, and the heating rod 8 to the power supply, ensuring a stable energized state. Since the first conductive ring 13, the second conductive ring 14, the heating rod 8, and the upper-mounted second power motor 11 are interconnected, when heating and stirring are required, the first power motor 5, the second power motor 11, and the second conductive ring 14 are simultaneously energized. Immediately afterwards, the power output of the first power motor 5 drives the limiting cylinder 7 to rotate. Because the limiting cylinder 7 is rotatably connected to the heating rod 8, and the limiting block 17 ensures the stability of the heating rod 8's rotation, the rotation of the limiting cylinder 7 will cause the heating rod 8 to rotate, ensuring full contact between the reaction materials and the heating rod 8, improving the uniformity and efficiency of heating. Simultaneously, the second power motor 11 starts, and its power output drives the worm gear 12 to rotate. Because the worm gear 12 is meshed with the outer surface of the worm wheel 9, the rotation of the worm gear 12 will cause the worm wheel 9 to rotate, thereby driving the heating rod 8 to rotate itself. The contact effect between the reaction raw materials and the heating rod 8 is further enhanced. During the rotation heating process of the heating rod 8, the scraper 16 is always in contact with the outer surface of the heating rod 8. As the limiting cylinder 7 rotates, the scraper 16 can effectively clean the scale and coking on the surface of the heating rod 8, preventing the increase of thermal resistance and damage to the heating rod 8 caused by scale and coking. When further cleaning of the inside of the equipment is required, water is supplied to the water inlet of the water spray plate 15. The water spray plate 15 sprays water to rinse the heating rod 8 and the inner wall of the tank 1, which can thoroughly remove the dirt and keep the inside of the equipment clean. The chemical raw materials enter the tank 1 from the feed hopper 2 for heating and reaction. After the reaction is completed, the reacted materials are discharged through the discharge valve 4. Throughout the process, the cooperation of the first conductive ring 13 and the second conductive ring 14 provides a stable power transmission for the heating rod 8, ensuring that the heating rod 8 can work continuously and stably even when rotating. This ensures the safe, reliable and efficient operation of the entire chemical heating reaction stirring tank, meeting the needs of chemical production.
