Description

Technical Field

[0001] This utility model relates to a reaction vessel dripping device. Background Technology

[0002] In a broad sense, a reaction vessel is a container where physical or chemical reactions occur. Through structural design and parameter configuration, it achieves the heating, evaporation, cooling, and low-to-high-speed mixing functions required by the process. Reaction vessels are widely used in petroleum, chemical, rubber, pesticide, dye, pharmaceutical, and food industries. They are pressure vessels used to complete processes such as vulcanization, nitration, hydrogenation, hydrocarbonation, polymerization, and condensation. Examples include reactors, reaction vessels, decomposition vessels, and polymerization kettles. Materials typically include carbon manganese steel, stainless steel, zirconium, nickel-based alloys (Hastelloy, Monel, Inconel), and other composite materials. In chemical production processes, it is often necessary to add certain chemical substances dropwise into the reaction vessel.

[0003] Existing reactor dripping equipment has limitations in operation. Due to the varying design, capacity, and internal structure of different reactors, the inlet height of the dripping equipment varies. A dripping device with a fixed height cannot accurately align with the inlets of reactors of different heights. This results in the dripping tube not being able to reach the appropriate dripping position inside the reactor, increasing operational complexity. Furthermore, it can only drip for one type of liquid, requiring reinstallation of the dripping equipment each time the liquid is changed. This process involves multiple steps such as disassembly, cleaning, and reassembly, reducing work efficiency. Utility Model Content

[0004] This invention addresses the technical problems encountered during use, such as the varying inlet heights of different reactors due to their design purpose, capacity, and internal structure.

Furthermore, these devices can only drip one type of liquid, requiring reinstallation each time the liquid is changed, involving multiple steps such as disassembly, cleaning, and reassembly, thus reducing work efficiency. Therefore, this invention provides a reactor dripping device.

[0008] In this technical solution, two sliding grooves are formed on the inner wall of the mounting shell, and two sliders are fixedly installed on the rack seat, with the sliders slidably connected to the sliding grooves.

[0009] In this technical solution, a plurality of auxiliary wheels are fixedly installed at the bottom of the rotating seat, and the bottom ends of the plurality of auxiliary wheels abut against the fixed seat.

[0010] In this technical solution, the rotating seat is provided with multiple liquid storage tanks, each of the multiple liquid storage tanks is threaded with a dust cover, each of the multiple liquid storage tanks is connected to a dripping tube, and each of the multiple dripping tubes is provided with a control valve.

[0011] In this technical solution, positioning blocks are fixedly installed on multiple liquid storage tanks, and multiple positioning slots are provided on the mounting column at equal intervals, and multiple positioning blocks can be inserted into the positioning slots.

[0013] In this technical solution, the base has a second through groove and two first through grooves inside. Two mounting brackets are fixedly installed on the base.

[0018] The positive and progressive effects of this utility model are as follows:

[0019] The aforementioned reaction vessel dropping device, by setting a limiting component, allows the rotating seat to be rotated to a suitable angle. By turning the handwheel, the rotating seat is further limited. By rotating the rotating seat, the corresponding storage tank of the required reagent can be easily switched to the dropping position. The operation is simple and quick, without the need for complicated disassembly and reinstallation, which greatly improves the convenience of operation. When the rotating seat switches the target storage tank to the appropriate position and is fixed by the limiting component, it can ensure that the relative position of the dropping tube and the outlet of the storage tank is stable. This helps to accurately control the dropping speed, flow rate and direction, avoids dropping errors caused by unstable position, and thus improves the accuracy and repeatability of the reaction.

[0020] By setting a fixing component, displacement of the storage tank during the rotation of the rotating seat can be prevented, thereby ensuring that the relative position of the dripping tube and the outlet of the storage tank is always accurate. This helps to achieve precise dripping operation, ensuring that the reagent is dripped into the reaction vessel according to the predetermined dosage, speed and direction, and helps to maintain a stable dripping flow rate.

[0021] By starting the motor, multiple side plates drive the fixed base to adjust their height, allowing the liquid storage tank to be easily adjusted to the optimal docking position with the feed inlet of the reactor at different heights. This ensures smooth dripping, reduces the risk of leakage, and improves the accuracy of dripping. It also allows for better adjustment of the height and angle of the liquid storage tank during tank switching, facilitating reconnection or adjustment with connecting pipes and ensuring the continuity of the entire dripping process. When cleaning or adding liquid to the storage tank is required, it can be lowered to a suitable height for easy operation by staff, reducing the difficulty and time cost of maintenance and repair.

[0037] In this technical solution, a plurality of auxiliary wheels 33 are fixedly installed at the bottom of the rotating seat 1, and the bottom ends of the plurality of auxiliary wheels 33 abut against the fixed seat 16.

[0038] In this technical solution, the rotating seat 1 is provided with a plurality of liquid storage tanks 2, each of the plurality of liquid storage tanks 2 is threadedly connected with a dust cover 3, each of the plurality of liquid storage tanks 2 is connected with a dripping tube 32, and each of the plurality of dripping tubes 32 is provided with a control valve 15.

[0039] In this technical solution, a positioning block 12 is fixedly installed on each of the multiple liquid storage tanks 2, and a multiple positioning grooves 11 are provided on the mounting column 4 at equal intervals, and the multiple positioning blocks 12 can be inserted into the positioning grooves 11.

[0040] In this technical solution, each of the multiple positioning blocks 12 is provided with a plug-in groove 10, and each of the multiple plug-in blocks 13 can extend into the interior of the positioning groove 11 and plug into the plug-in groove 10.

[0041] In this technical solution, the base 26 has a second through groove 23 and two first through grooves 22 inside. Two mounting brackets 20 are fixedly installed on the base 26. The interior of each mounting bracket 20 is rotatably connected to a lead screw 18 via a bearing.

[0044] In this technical solution, four brake casters 21 are fixedly installed at the bottom end of the base 26.

[0045] In use, all electrical components are externally connected to a power supply and control switch. Multiple liquid storage tanks 2 are provided. After the reagent in one tank 2 has been added, the rotating seat 1 can be rotated to switch to the next tank 2 containing reagent, achieving uninterrupted adding. The motor 29 is started, and its output shaft drives the driven gear 24 to rotate via the driving gear 30. The driven gear 24 drives two first gears 27 to rotate via the rotating rod 25. The two first gears 27 drive the lead screw 18 to rotate via the second gear 28. With the cooperation of the two limit rods 17, the two movable blocks 19 move along the surface of the lead screw 18. The vertical movement of the side plates 31 allows for height adjustment of the fixed base 16, facilitating the adjustment of the liquid storage tank 2 to the optimal docking position with the feed inlet of the reactor at different heights. This ensures smooth dripping, reduces the risk of leakage, and improves the accuracy of dripping. Furthermore, it allows for better adjustment of the height and angle of the liquid storage tank 2 during switching processes, facilitating reconnection or adjustment with connecting pipes and ensuring the continuity of the entire dripping process. When cleaning or adding liquid to the liquid storage tank 2 is required, it can be lowered to a suitable height for easy operation by staff, reducing the difficulty and time cost of maintenance and repair.

[0046] Rotate the rotating seat 1 to a suitable angle, turn the handwheel 39, and the handwheel 39 will drive the screw 38 to rotate and move at the same time. With the cooperation of the slide groove 40 and the slider 41, the screw 38 will drive the rack seat 37 to approach the limiting gear 34, limit the limiting gear 34, and then limit the rotating seat 1. By rotating the rotating seat 1, the storage tank 2 corresponding to the required reagent can be easily switched to the dripping position. The operation is simple and quick, without the need for complicated disassembly and reinstallation, which greatly improves the convenience of operation. When the rotating seat 1 switches the target storage tank 2 to a suitable position and is fixed by the limiting component, it can ensure that the relative position of the dripping tube 32 and the outlet of the storage tank 2 is stable, which helps to accurately control the dripping speed, flow rate and direction, avoid dripping errors caused by unstable position, and thus improve the accuracy and repeatability of the reaction.

[0047] Pulling the pull ring 6 causes the connecting rod 7 to move via the pull plate 5. The connecting rod 7, through the connecting plate 9, causes multiple insertion blocks 13 to move away from the positioning groove 11, placing the storage tank 2 on the rotating seat 1 so that the positioning block 12 is inserted into the positioning groove 11. Releasing the pull ring 6, with the cooperation of the spring 14, causes multiple insertion blocks 13 to be inserted into the insertion groove 10. This prevents the storage tank 2 from shifting during the rotation of the rotating seat 1, thus ensuring that the relative position of the dripping tube 32 and the outlet of the storage tank 2 is always accurate. This helps to achieve precise dripping operation, ensuring that the reagent is dripped into the reaction vessel according to the predetermined dosage, speed, and direction, and helps to maintain a stable dripping flow rate.

[0048] The advantages of this application are:

[0049] 1. By setting a limiting component, the rotating seat 1 is rotated to a suitable angle, and the handwheel 39 is turned to limit the rotating seat 1. By rotating the rotating seat 1, the storage tank 2 corresponding to the required reagent can be easily switched to the dripping position. The operation is simple and quick, without the need for complicated disassembly and reinstallation, which greatly improves the convenience of operation. When the rotating seat 1 switches the target storage tank 2 to a suitable position and is fixed by the limiting component, it can ensure that the relative position of the dripping tube 32 and the outlet of the storage tank 1 is stable. This helps to accurately control the dripping speed, flow rate and direction, avoid dripping errors caused by unstable position, and thus improve the accuracy and repeatability of the reaction.

[0050] 2. By setting a fixing component, displacement of the storage tank 2 during the rotation of the rotating seat 1 can be prevented, thereby ensuring that the relative position of the dripping tube 32 and the outlet of the storage tank 2 is always accurate. This helps to achieve precise dripping operation, ensuring that the reagent is dripped into the reaction vessel according to the predetermined dosage, speed and direction, and helps to maintain a stable dripping flow rate.

[0051] 3. By starting the motor 29, the multiple side plates 31 drive the fixed base 16 to adjust their height, which can easily adjust the liquid storage tank 2 to the optimal docking position of the feed inlet of the reactor at different heights, ensuring smooth dripping, reducing the risk of leakage during dripping, improving the accuracy of dripping, and allowing for better adjustment of the height and angle of the liquid storage tank 2 during switching, facilitating reconnection or adjustment with connecting pipes, ensuring the continuity of the entire dripping process. When it is necessary to clean or add liquid to the liquid storage tank 2, the liquid storage tank 2 can be lowered to a suitable height, making it convenient for staff to operate and reducing the difficulty and time cost of maintenance and repair.
