Description

Technical Field

[0001] The utility model relates to the field of reaction kettles, in particular to a subcritical hydrolysis reaction kettle for the biocarbonization of domestic waste. Background Technique

[0002] The working principle of the hydrolysis reaction kettle is relatively simple. Its main components include a reaction kettle, a heater, a cooler, a stirrer, a pressure gauge, etc. The hydrolysis reaction kettle is mainly used to decompose compounds into their constituent atoms or molecules by adding and decomposing water under high temperature and high pressure. This process usually involves the reaction of ions ionized from salts with hydrogen ions and hydroxide ions ionized from water in the solution to form weak electrolytes.

[0003] The Chinese utility model patent with the publication number of CN221108261U discloses an efficient stirrer for a glass-lined reaction kettle used in chemical industry and medicine. It fixedly connects a scraper through a stirring rod, and the scraper rotates closely against the inner wall of the kettle body, so as to simultaneously complete the stirring of the reactants in the reaction kettle and facilitate scraping off the materials attached to the inner wall of the kettle body. However, most of the stirrers of such reaction kettles are common stirring rod structures. In the actual use process of the hydrolysis reaction kettle, in order for the reactants to react quickly, a high temperature and high pressure environment is often required. The existing mechanism lacks means to combine air pressure and stirring, resulting in a still slow reaction rate of the reactants.

[0004] Therefore, a subcritical hydrolysis reaction kettle for the biocarbonization of domestic waste is provided to solve the above problems. Content of the Utility Model

[0005] (1) Technical Problems to be Solved

[0006] The utility model provides a subcritical hydrolysis reaction kettle for the biocarbonization of domestic waste, aiming to solve the problem that most of the stirrers of the existing reaction kettles in the background technique are common stirring rod structures. In the actual use process of the hydrolysis reaction kettle, in order for the reactants to react quickly, a high temperature and high pressure environment is often required. The existing mechanism lacks means to combine air pressure and stirring, resulting in a still slow reaction rate of the reactants.

[0007] Technical Solution

[0008] To achieve the above purpose, the utility model provides the following technical solution: A subcritical hydrolysis reaction kettle for the biocarbonization of domestic waste, including a reaction kettle body and a pneumatic control valve installed on the reaction kettle body, and a multi-functional stirring mechanism is installed on the reaction kettle body:

[0009] In order to accelerate the reaction rate of the reactants in the reactor body, the multifunctional stirring mechanism includes a driving motor fixedly installed at the top of the reactor body, a stirring rod fixedly connected to the output end of the driving motor and extending into the reactor body, and three groups of circumferentially arranged bubble supplement components arranged on the inner wall of the reactor body;

[0010] The bubble supplement component includes a main pipe fixedly installed on the outer wall of the reactor body. A connecting pipe for connecting an air pump is fixedly installed on the outer side wall of the main pipe. Two L-shaped branch pipes extending into the reactor body are opposed at both ends of the main pipe. A number of uniformly arranged nozzles are fixedly installed on the outer wall of the branch pipe in the reactor body. While the driving motor drives the stirring rod to rotate to stir the reactants in the reactor body, an external air pump supplies gas to the main pipe through the connecting pipe. The gas enters the reactor body through the branch pipe and is ejected into the reaction solution in the reactor body through the nozzles, so that the reaction solution is filled with bubbles. At the same time, the pressure control valve monitors and controls the stability of the air pressure in the reactor body, enabling the device to have the functions of mechanical stirring and bubble supplement reaction, thus effectively improving the reaction rate and making the reaction more sufficient and efficient.

[0011] Preferably, in order to stir the materials in the reactor body, the stirring rod includes a main rotating rod fixedly connected to the output end of the driving motor and arranged inside the reactor body. At least three cross bars are fixedly installed on the outer side wall of the main rotating rod corresponding to the middle notch positions of the two L-shaped branch pipes. A number of vertical rods are fixedly installed vertically on the outer side wall of the cross bars. By driving the main rotating rod to rotate through the driving motor, the main rotating rod drives the cross bars to rotate, and the cross bars drive the vertical rods thereon to rotate, thereby stirring the reactants in the reactor body and accelerating the reaction generation. The operation is convenient and fast.

[0012] Preferably, in order to improve the stability of the main rotating rod, a support seat is fixedly installed at the inner bottom of the reactor body. The top of the support seat is adapted to the bottom end of the main rotating rod. When installing the main rotating rod, the bottom of the main rotating rod is aligned with the support seat, so that the bottom does not hang in the air during its rotation and the rotation is more stable.

The cleaning mechanism includes a scraping strip fixedly installed at the end of the cross bar away from the main rotating rod and a water supply bypass installed on the outer wall of the connecting pipe for connecting a water pump. A valve is installed on the water supply bypass. By changing the connection channel of the connecting pipe through the valve, it is connected to the water supply bypass. Subsequently, water is supplied by the water pump through the main pipe into the two L-shaped branch pipes, and then sprayed out through the nozzles, so that the three groups of L-shaped branch pipes at the inner wall of the reactor body spray out water mist simultaneously and spray onto the side wall of the reactor body. At the same time, the driving motor is started to drive the stirring rod to rotate, and the stirring rod drives the scraping strip connected thereto to rotate, cleaning the inner wall of the reactor body more thoroughly. Moreover, it has the function of multi-purpose use for the bubble supplement component, and the practicability is better.

[0014] Preferably, to ensure the normal operation of the scraping strip, the length of the scraping strip is the same as the width remaining at the opposite position of the two L-shaped branch pipes. The scraping strip is arranged in contact with the inner side wall of the reactor body. The scraping strip extends between the two L-shaped branch pipes through the support of the cross bar, so as to contact the inner wall of the reactor body, without structural conflict and convenient to use.

[0015] Preferably, in order to clean the inner wall of the reactor body more thoroughly, a card slot is opened on the outer side wall of the scraping strip, and a brush plate is inserted into the card slot. The inner wall of the reactor body is scraped by the flexible and detachable brush plate. When in use, the brush plate is inserted into the scraping strip from above through the card slot, and then it can clean the inner wall of the reactor body following the rotation of the main rotating rod. When disassembling, just pull out the brush plate from above the scraping strip, which is convenient and fast.

[0016] (III) Beneficial effects

The gas enters the reactor body through the branch pipes and is sprayed out in the reaction solution in the reactor body through the nozzles, so that the reaction solution is filled with bubbles. At the same time, the pressure control valve monitors and controls the stability of the pressure in the reactor body, enabling the equipment to have the functions of mechanical stirring and bubble supplement reaction, thus effectively improving the reaction speed and making the reaction more sufficient and efficient.

[0018] For this hydrolysis reactor, by changing the connection channel of the connecting pipe through the valve, it is connected to the water supply bypass. Subsequently, water is supplied by the water pump through the main pipe into the two L-shaped branch pipes, and then sprayed out through the nozzles, so that the three groups of L-shaped branch pipes at the inner wall of the reactor body spray out water mist simultaneously and spray onto the side wall of the reactor body.

The gas enters the reactor body 1 through the branch pipe 333 and is ejected into the reaction solution in the reactor body 1 through the nozzles 334, so that the reaction solution is filled with bubbles.

Subsequently, the water pumped by the water pump enters the two L-shaped branch pipes 333 through the main pipe 331 and then sprays out through the nozzles 334, so that the three groups of L-shaped branch pipes 333 on the inner wall of the reactor body 1 spray water mist simultaneously towards the side wall of the reactor body 1.
