Description

Technical Field

[0001] The utility model relates to the technical field of reaction kettles, in particular to a multi-pipe chemical reaction kettle. Background Art

[0002] A reaction kettle is a device used for carrying out chemical reactions and is widely used in the production processes of industries such as chemical engineering, pharmaceuticals, and food. It is usually made of corrosion-resistant materials such as stainless steel and fiberglass to ensure that it can withstand the requirements of working conditions such as high temperature, high pressure, corrosive substances, and stirring during the chemical reaction process.

[0003] In view of the above and existing related technologies, the applicant believes that the following defects often exist: when using a reaction kettle for chemical reaction operations, after the chemical raw materials in the reaction kettle are mixed and heated, chemical steam will be ejected from the steam nozzle. Since the chemical steam contains a large amount of decomposition products of chemical raw materials, harmful gases that are not conducive to human health are contained in the chemical steam. Workers staying in the chemical reaction workshop for a long time inhale the chemical waste gas, which seriously affects the physical health of the workers.

[0004] The existing Chinese patent with the publication number CN221601953U discloses a multi-pipe chemical reaction kettle, which relates to the technical field of reaction kettles, including a reaction kettle body. A plurality of feed pipes are communicated with the surface of the reaction kettle body. A viewing window is fixedly connected to the surface of the reaction kettle body. A motor is fixedly connected to the upper surface of the reaction kettle body. The output end of the motor is fixedly connected to a transmission shaft. The other end of the transmission shaft is fixedly connected to a stirring paddle. A plurality of steam nozzles are communicated with the surface of the reaction kettle body. A filtering device is provided at one end of the steam nozzle. The filtering device includes a filtering box, the filtering box is communicated with the steam nozzle, a filtering box is fixedly connected to the inner wall of the filtering box, and a sponge block is slidably connected to the inner wall of the filtering box.

[0005] In view of the above and existing related technologies, the inventor believes that the following defects often exist: when collecting the water adsorbed by the sponge block through a collecting box, the water cannot flow back into the reaction kettle, resulting in waste and needs to be improved; therefore, a multi-pipe chemical reaction kettle is proposed for the above problems. Content of the Utility Model

[0006] In order to make up for the deficiencies of the existing technology and solve the above-mentioned technical problems, the utility model proposes a multi-pipe chemical reaction kettle.

[0007] The technical solution adopted by the present utility model to solve its technical problems is as follows: A multi-material pipe chemical reaction kettle of the present utility model includes a reaction kettle body, and a plurality of feed pipes are installed on the reaction kettle body. The multiple feed pipes can prevent a single feed pipe from being blocked and affecting the feeding. A stirring device is installed at the center of the reaction kettle body. An outlet end is installed at the bottom of the reaction kettle body, and a discharge valve is installed on the outlet end. A gas outlet pipe is fixedly connected to the side wall of the reaction kettle body. The other end of the gas outlet pipe is fixedly connected to a separation cylinder. A return pipe is fixedly connected to the bottom of the separation cylinder, and the other end of the return pipe is fixedly connected to the reaction kettle body. An adsorption assembly is installed inside the separation cylinder. The adsorption assembly includes an orifice plate and a pressing plate. The orifice plate is fixedly installed inside the separation cylinder. A narrow channel is provided inside the separation cylinder. The orifice plate is located inside the narrow channel. The diameter of the pressing plate is smaller than the diameter of the narrow channel. A sponge adsorption layer is fixedly connected above the orifice plate. Chemical materials are added into the reaction kettle body through the feed pipes and stirred by the stirring device for chemical reaction. The chemical steam in the reaction kettle body enters the separation cylinder through the gas outlet pipe. The moisture in the gas is adsorbed by the sponge adsorption layer. When the electric push rod runs to drive the pressing plate to press down the sponge adsorption layer, the moisture can be squeezed out and returned to the reaction kettle body through the return pipe, thereby reducing waste.

[0008] Preferably, the adsorption assembly further includes a fixing ring. The fixing ring is fixedly installed inside the separation cylinder. An electric push rod is fixedly connected to the center of the fixing ring, and the driving end of the electric push rod is fixedly connected to the pressing plate.

[0009] Preferably, a pressure detector is fixedly connected to the gas outlet pipe. The pressure detector can detect the pressure inside the reaction kettle body and open the control valve to discharge the chemical steam when the pressure is too high.

[0010] Preferably, a control valve is installed on the gas outlet pipe.

[0011] Preferably, a purification cylinder is fixedly connected to the top of the separation cylinder. Thread grooves are tapped and opened at both ends of the purification cylinder. Solenoid valves are respectively installed on both sides of the purification cylinder. A purification assembly is installed on the purification cylinder. The purification assembly includes two limiting rings. The limiting rings are respectively installed inside both ends of the purification cylinder. Sliding grooves are respectively opened on the inner walls of both ends of the purification cylinder, and the limiting rings are slidably connected to the sliding grooves. The chemical steam enters the purification cylinder after separating moisture in the separation cylinder, is purified by the activated carbon filter layer and then discharged, thereby reducing the pollution of harmful gases in the chemical steam to the workshop. By alternately controlling the opening of the two solenoid valves, the gas discharge direction of the purification cylinder is controlled, so that the activated carbon filter layers at both ends of the separation cylinder are used alternately. Furthermore, when replacing the activated carbon filter layer, the purification operation is not affected.

[0012] Preferably, springs are fixedly connected to both ends of the limiting ring, and the other ends of the springs are fixedly installed inside the sliding groove.

[0013] Preferably, an activated carbon filter layer and a threaded ring are sequentially installed on one side of the limiting ring from outside to inside. The threaded ring is threadedly connected to the purification cylinder. The activated carbon filter layer is restricted inside the purification cylinder through the threaded ring. When the activated carbon filter layer needs to be replaced, the threaded ring is removed, and the limiting ring automatically pops out the activated carbon filter layer through the tension of the spring, facilitating replacement.

[0014] Preferably, the purification assembly further includes a driver, which is fixedly installed at the center of the top of the purification cylinder. The driving end of the driver is fixedly connected to an L-shaped mounting bracket. A gas detector is fixedly connected to the lower side wall of the mounting bracket.

When the activated carbon filter layer fails, the content of harmful gases in the discharged gas is detected to increase, and then a signal is transmitted to control the alarm to give an alarm, so as to remind the staff to change the gas discharge direction of the purification cylinder and replace the activated carbon filter layer in time. Moreover, the driver drives the mounting bracket to rotate, so that the gas detector can adjust its position according to the gas discharge direction to detect the gas in real time.

[0016] 1. In the present utility model, the chemical steam in the reaction kettle body enters the separation cylinder through the air outlet pipe. The sponge adsorption layer adsorbs the moisture in the gas. When the electric push rod operates to drive the pressing plate to press down the sponge adsorption layer, the moisture can be squeezed out and refluxed to the reaction kettle body through the reflux pipe, thereby reducing waste.

[0017] 2. The present utility model is discharged after being purified by the activated carbon filter layer, thereby reducing the pollution of harmful gases in the chemical steam to the workshop. By alternately controlling the opening of two solenoid valves, the gas discharge direction of the purification cylinder is controlled, so that the activated carbon filter layers at both ends of the separation cylinder are used alternately. Therefore, when the activated carbon filter layer is replaced, the purification operation is not affected. Description of the Drawings

The side wall of the reactor body 1 is fixedly connected with an air outlet pipe 5, and the other end of the air outlet pipe 5 is fixedly connected with a separation cylinder 6. The bottom of the separation cylinder 6 is fixedly connected with a return pipe 8, and the other end of the return pipe 8 is fixedly connected with the reactor body 1. An adsorption assembly 7 is installed inside the separation cylinder 6. The adsorption assembly 7 includes an orifice plate 71 and a pressing plate 72.

A narrow channel is provided inside the separation cylinder 6, and the orifice plate 71 is located inside the narrow channel. The diameter of the pressing plate 72 is smaller than the diameter of the narrow channel. A sponge adsorption layer 75 is fixedly connected above the orifice plate 71. Chemical materials are added into the reactor body 1 through the feed pipe 2 and stirred by the stirring device 3 for chemical reaction. The chemical vapor in the reactor body 1 enters the separation cylinder 6 through the air outlet pipe 5. The moisture in the gas is adsorbed by the sponge adsorption layer 75. When the electric push rod 74 operates to drive the pressing plate 72 to press down the sponge adsorption layer 75, the moisture can be squeezed out and returned to the reactor body 1 through the return pipe 8, thus reducing waste.

[0028] The adsorption assembly 7 further includes a fixing ring 73. The fixing ring 73 is fixedly installed inside the separation cylinder 6.

[0029] A pressure detector 9 is fixedly connected to the air outlet pipe 5. The pressure detector 9 can detect the pressure inside the reactor body 1 and open the control valve 10 to discharge the chemical vapor when the pressure is too high.

[0030] A control valve 10 is installed on the air outlet pipe 5.

[0031] Embodiment 2

[0032] Comparing with Embodiment 1, please refer to Figures 4-5As shown in the figure, the present utility model provides another embodiment. The top of the separation cylinder 6 is fixedly connected with a purification cylinder 11, and threaded grooves are tapped and opened at both ports of the purification cylinder 11. Solenoid valves 13 are respectively installed on both sides of the purification cylinder 11, and a purification component 12 is installed on the purification cylinder 11. The purification component 12 includes two limiting rings 121, which are respectively installed inside both ends of the purification cylinder 11. Sliding grooves are respectively opened on the inner walls of both ends of the purification cylinder 11, and the limiting rings 121 are slidably connected with the sliding grooves. After the chemical vapor separates moisture in the separation cylinder 6, it enters the purification cylinder 11, and is discharged after being purified by the activated carbon filter layer 123, thereby reducing the pollution of harmful gases in the chemical vapor to the workshop, effectively improving the working environment of the staff, and ensuring the physical health of the staff to a certain extent. By alternately controlling the opening of the two solenoid valves 13, the gas discharge direction of the purification cylinder 11 is controlled, so that the activated carbon filter layers 123 at both ends of the separation cylinder 6 are used alternately. Furthermore, when replacing the activated carbon filter layer 123, the purification operation is not affected.

[0033] Both ends of the limiting ring 121 are respectively fixedly connected with springs 122, and the other ends of the springs 122 are fixedly installed inside the sliding grooves. When the activated carbon filter layer 123 is installed inside the purification cylinder 11, it will push the limiting ring 121 to compress the spring 122.

[0034] On one side of the limiting ring 121, an activated carbon filter layer 123 and a threaded ring 124 are sequentially installed from outside to inside. The threaded ring 124 is threadedly connected with the purification cylinder 11. The activated carbon filter layer 123 is restricted inside the purification cylinder 11 through the threaded ring 124. When the activated carbon filter layer 123 needs to be replaced, the threaded ring 124 is removed, and the limiting ring 121 automatically ejects the activated carbon filter layer 123 through the tension of the spring 122, which is convenient for replacement.

[0035] The purification component 12 further includes a driver 125, which is fixedly installed at the center of the top of the purification cylinder 11. The driving end of the driver 125 is fixedly connected with an L-shaped mounting bracket 126. The lower side wall of the mounting bracket 126 is fixedly connected with a gas detector 127. The gas detector 127 is electrically connected with an alarm. By detecting one end of the gas discharged from the purification cylinder 11 through the gas detector 127, when the activated carbon filter layer 123 fails, it is detected that the content of harmful gases in the discharged gas increases, and then a signal is transmitted to control the alarm to give an alarm, so as to remind the staff to change the gas discharge direction of the purification cylinder 11 and replace the activated carbon filter layer 123 in time. Moreover, the driver 125 drives the mounting bracket 126 to rotate, so that the gas detector 127 can adjust its position according to the gas discharge direction to detect the gas in real time.

[0036] Persons skilled in the art shall connect all the electrical components in this case to their adapted power supplies through wires, and should, according to the actual situation, select a suitable controller and electrically connect it to the stirring device 3, electric pusher, air pressure detector 9, gas detector 127 and alarm to meet the control requirements. For the specific connection and control sequence, reference should be made to the sequence of operation among the electrical components in the following working principle to complete the electrical connection. The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process, and no further description of electrical control will be given.

[0037] The parts not involved in this device are the same as the prior art or can be implemented by using the prior art.

[0038] Working principle: Chemical materials are added into the reaction kettle body 1 through the feed pipe 2, and a chemical reaction is carried out by stirring with the stirring device 3. The chemical steam in the reaction kettle body 1 enters the separation cylinder 6 through the air outlet pipe 5. The water in the gas is adsorbed by the sponge adsorption layer 75. When the electric push rod 74 operates to drive the pressing plate 72 to press down the sponge adsorption layer 75, the water can be squeezed out and refluxed to the reaction kettle body 1 through the reflux pipe 8, thus reducing waste.

[0039] After the chemical steam is separated from water in the separation cylinder 6, it enters the purification cylinder 11, is purified by the activated carbon filter layer 123 and then discharged, thus reducing the pollution of harmful gases in the chemical steam to the workshop, effectively improving the working environment of the staff, and ensuring the physical health of the staff to a certain extent. By alternately controlling the opening of the two solenoid valves 13, the gas discharge direction of the purification cylinder 11 is controlled, so that the activated carbon filter layers 123 at both ends of the separation cylinder 6 are used alternately. Thus, when the activated carbon filter layer 123 is replaced, the purification operation is not affected.

[0040] The gas detector 127 detects one end of the gas discharged from the purification cylinder 11. Thus, when the activated carbon filter layer 123 fails, it is detected that the content of harmful gases in the discharged gas increases, and then a signal is transmitted to control the alarm to give an alarm, so as to remind the staff to change the gas discharge direction of the purification cylinder 11 and replace the activated carbon filter layer 123 in time. Moreover, the driver 125 drives the mounting bracket 126 to rotate, so that the gas detector 127 can adjust its position according to the gas discharge direction to detect the gas in real time.
