Technical Field
[0001] The utility model belongs to the technical field of reaction kettles, in particular to a leakage-proof reaction kettle for compound fertilizers. Background Art
[0002] Compound fertilizer refers to a fertilizer containing two or more nutrients of nitrogen, phosphorus and potassium. Compound fertilizer has the advantages of high nutrient content, few by-components and good physical properties. It plays a very important role in balanced fertilization, improving fertilizer utilization and promoting high and stable yield of crops. In the production and processing of compound fertilizer, a reactor is usually used to process a variety of raw materials at high temperature and high pressure to make the mixed reaction of the various raw materials sufficient to ensure the quality of the product. The reactor is a container with physical or chemical reactions. Through the structural design and parameter configuration of the container, the heating, evaporation, cooling and low-speed mixing functions required by the process are realized. It is widely used in the fields of petroleum, chemical industry, rubber, pesticides, dyes, medicine and food, but it still has the following disadvantages in actual use:
[0003] 1. The utility model with the publication number CN219879933U discloses a leak-proof micro reactor, wherein a discharge pipe is provided through one end of the reactor body, a water pump is provided above the reactor body near one end of the discharge pipe, the input end of the water pump is connected to an external water pipe, the output end of the water pump is provided with a water delivery pipe, a sealing sleeve is provided outside the water delivery pipe, a discharge annular pipe is provided at one end of the water delivery pipe away from the water pump, and nozzles are evenly provided at the bottom end of the discharge annular pipe, a feeding pipe is provided through the reactor body away from one end of the discharge pipe, a support seat is provided above the outside of the feeding pipe, a sealing cover is provided at the top of the support seat, and a sealing gasket is provided at the central position of the bottom end of the sealing cover. The reactor usually improves the sealing performance during processing by adding sealing structures, such as sealing sleeves, sealing gaskets, etc., to avoid leakage of toxic and harmful gases. However, when the reactor is used for a long time, the sealing structure will inevitably wear out. To ensure the sealing performance, the reactor often needs to be regularly checked for sealing performance, and the sealing structure needs to be regularly replaced, which increases maintenance expenses;
[0004] 2. Leakage-proof reactors are usually equipped with feed pipes, discharge pipes, etc., and the feed pipes and discharge pipes usually require valves for opening and closing. The feed pipes and discharge pipes are often fixed to the surface of the reactor by welding, and there are many locations prone to leakage, resulting in poor sealing of the reactor. Utility Model Content
[0005] The utility model aims to provide a leak-proof reactor for compound fertilizers. Through the leak-proof tank, the leak-proof top cover and the reactor body, the problems that the sealing structure of the reactor is inevitably worn out after long-term use, the sealing performance needs to be tested regularly, and the sealing structure needs to be replaced regularly, and the inlet and outlet pipes of the reactor have many leakage points are solved.
[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:
[0007] The utility model is a leakage-proof reactor for compound fertilizer, comprising a leakage-proof tank, a leakage-proof top cover and a reactor body, a reflux pipe is penetrated and welded at the bottom of the outer peripheral surface of the leakage-proof tank, a high-pressure air pump is clamped and fixed at the top of the leakage-proof tank, a processing pipe is arranged at the top of the high-pressure air pump, a filter element is screwed and fixed at the other end of the processing pipe, a reactor body is arranged inside the leakage-proof tank, a reactor top cover is clamped and fixed at the top of the reactor body, a third hopper is penetrated and welded at the top of the reactor top cover, and a feed pipe is penetrated and welded at the center of the bottom of the reactor body;
[0008] The air inside the anti-leakage tank can be extracted by a high-pressure air pump, so that the anti-leakage tank is in a relative vacuum. The excess waste gas generated by the reactor body in the raw material processing will make up for the pressure difference between the inside and outside of the anti-leakage tank when it is discharged into the anti-leakage tank, so as to avoid the waste gas from leaking into the environment under high pressure due to the high pressure in the reactor body. The relative vacuum can better insulate the internal machine of the reactor body. After the waste gas is generated in the reactor body and discharged into the anti-leakage tank, the waste gas is driven through the reaction tube by the high-pressure air pump, so that the waste gas and the filter element can be contacted to treat the waste gas. The third hopper and the discharge pipe of the reactor body do not contact the outer peripheral surface of the anti-leakage tank, so as to avoid the easy leakage position of the reactor body from contacting the outside world, and further avoid the leakage of waste gas. The anti-leakage tank is at a low pressure relative to the external environment, which further avoids the waste gas discharged from the reactor body from leaking through the inlet and outlet positions of the anti-leakage tank and the anti-leakage top cover. At the same time, there is no need to regularly check the sealing of the reactor, thereby reducing maintenance expenses.
[0009] Furthermore, a first support frame is welded and fixed to the bottom edge of the leak-proof tank, a first hopper is welded through the center of the bottom of the leak-proof tank, a discharge pipe is welded through the bottom of the first hopper, and the discharge pipe is suspended from the top of the first hopper;
[0010] The processed material is discharged through the discharge pipe and falls into the first hopper under the action of gravity, and is discharged through the discharge pipe. The discharge pipe does not contact the discharge pipe of the anti-leakage tank, avoiding the contact between the leakage-prone position of the reactor body and the outside world, and further avoiding the leakage of exhaust gas.
[0011] Furthermore, a second hopper is welded through the top of the leak-proof top cover, the second hopper is suspended from the top of the third hopper, one end of the high-pressure air pump is penetrated and clamped with an exhaust pipe, and the other end of the exhaust pipe is penetrated and clamped with the top of the leak-proof top cover;
[0012] Before processing, the raw materials are poured into the inner side of the second hopper. Under the action of gravity, the raw materials fall into the reactor body through the third hopper for processing. The third hopper does not contact the second hopper of the leakage-proof tank, so that the waste gas generated during the reaction of the raw materials leaks into the inner side of the leakage-proof tank, avoiding the waste gas from being directly discharged into the environment and causing pollution to the environment. The inside of the leakage-proof tank is at a relatively low pressure relative to the external environment, avoiding the waste gas from leaking through the inlet and outlet positions of the leakage-proof tank and the leakage-proof top cover.
[0013] Furthermore, an exhaust pipe is inserted through the top of the outer peripheral surface of the high-pressure air pump, the treatment pipe is inserted through and welded to the outer peripheral surface of the exhaust pipe, the bottom end of the treatment pipe is inserted into the top of the return pipe, and the filter element is inserted into the inner side of the return pipe;
[0014] Before the raw materials are processed, the air in the leak-proof tank can be extracted through a high-pressure air pump to make the inside of the leak-proof tank a relative vacuum. The excess waste gas generated by the raw material processing by the reactor body will be discharged into the leak-proof tank to make up for the pressure difference inside and outside the leak-proof tank, so as to avoid the waste gas from leaking into the environment under high pressure due to the high air pressure in the reactor body. The waste gas generated during the processing is pumped into the treatment pipe by a high-pressure air pump, filtered through the filter element, and refluxed through the reflux pipe. The treated gas is then discharged through the exhaust pipe, which improves the convenience of using the reactor.
[0015] Furthermore, a second support frame is clamped and fixed at the bottom edge of the reactor body, the second support frame is clamped on the inner side of the anti-leakage tank, a stirring motor is clamped and fixed at the center of the top of the reactor cover, a rotating rod is clamped at the bottom of the stirring motor, a stirring blade is clamped and fixed on the outer peripheral surface of the rotating rod, and the rotating rod penetrates and is inserted into the top of the reactor cover;
[0016] The stirring motor can drive the stirring blades to rotate, stir the raw materials, mix the raw materials evenly, and improve the reaction efficiency. During the reaction and mixing process of the raw materials, the lower air pressure in the leak-proof tank can further improve the thermal insulation of the reactor body and reduce heat loss.
[0017] The utility model has the following beneficial effects:
[0018] 1. The utility model solves the problem that the reactor usually increases the sealing performance during processing by adding sealing structures, such as sealing sleeves, sealing gaskets, etc., to avoid leakage of toxic and harmful gases by arranging a leak-proof tank and a leak-proof top cover. However, when the reactor is used for a long time, the sealing structure will inevitably wear out. To ensure the sealing performance, the reactor often needs to be regularly inspected for sealing performance, and the sealing structure needs to be regularly replaced, which increases the maintenance cost. The air in the leak-proof tank is extracted by a high-pressure air pump to make the inside of the leak-proof tank a relative vacuum. The exhaust gas discharged from the reactor body during the reaction can make up for the pressure difference between the leak-proof tank and the external environment, so as to avoid the exhaust gas from leaking into the environment under high pressure due to the high air pressure in the reactor body.
[0019] 2. The utility model solves the problem that a leak-proof reactor is usually provided with a feed pipe, a discharge pipe, etc., and the feed pipe and the discharge pipe, etc. usually need to be provided with valves for opening and closing, and the feed pipe and the discharge pipe are often fixed to the surface of the reactor by welding, and there are many positions prone to leakage, resulting in poor sealing of the reactor. The raw materials in the second hopper of the inverted leak-proof top cover enter the reactor body through the third hopper under the action of gravity for processing. After the processing is completed, the materials fall into the discharge pipe of the leak-proof tank through the discharge pipe under the action of gravity for discharge, thereby avoiding the contact between the feed and discharge interfaces of the reactor and the external environment. The leak-proof tank is at a low pressure relative to the external environment, further avoiding the exhaust gas discharged from the reactor body from leaking through the feed and discharge positions of the leak-proof tank and the leak-proof top cover. At the same time, there is no need to conduct regular inspections on the sealing of the reactor, thereby reducing maintenance expenses. BRIEF DESCRIPTION OF THE DRAWINGS

The second hopper 204 and the third hopper 302 are closed and the high-pressure air pump 201 is turned on. The air inside the anti-leakage tank 1 is extracted by the high-pressure air pump 201, so that the anti-leakage tank 1 is in a relative vacuum. When the reactor body 3 processes the raw materials, a certain amount of waste gas is generated, so that the reactor body 3 is in a relatively high air pressure. The leaked waste gas escapes into the anti-leakage tank 1, and the waste gas is extracted into the treatment pipe 202 by the high-pressure air pump 201, filtered by the filter element 203, so that the waste gas is harmlessly treated, and the treated gas and the air leaked from the external environment into the anti-leakage tank 1 are discharged through the exhaust pipe 205 at a regular time by the high-pressure air pump 201. After the processing is completed, the discharge pipe 104 and the lower pipe 307 are opened, and the material is discharged through the lower pipe 307 and the discharge pipe 104 under the action of gravity.

[0031] During the material processing, the leaked exhaust gas is processed through the treatment pipe 202 and refluxed into the anti-leakage tank 1 through the reflux pipe 102 to avoid large-scale loss of direct heat. After the material processing is completed, the discharge pipe 104 is opened, and the material falls to the inside of the first hopper 103 under the action of gravity and is discharged through the discharge pipe 104.
[0032] Among them Figure 1 , 2 As shown in , 4, the second hopper 204 is welded through the top of the leak-proof top cover 2, and the second hopper 204 is suspended on the top of the third hopper 302. One end of the high-pressure air pump 201 is penetrated and connected with a suction pipe 206, and the other end of the suction pipe 206 is penetrated and connected to the top of the leak-proof top cover 2. The top of the outer peripheral surface of the high-pressure air pump 201 is penetrated and connected with an exhaust pipe 205, and the processing pipe 202 is penetrated and welded to the outer peripheral surface of the exhaust pipe 205. The bottom end of the processing pipe 202 is connected to the top of the return pipe 102, and the filter element 203 is plugged into the inner side of the return pipe 102;
[0033] Before processing, the raw materials are poured into the inner side of the second hopper 204. Under the action of gravity, the raw materials fall into the reactor body 3 through the third hopper 302 for processing. The second hopper 204 and the third hopper 302 are closed, the exhaust pipe 205 is opened and the treatment pipe 202 is closed, the high-pressure air pump 201 is turned on, and the anti-leakage tank 1 is evacuated to a relative vacuum through the exhaust pipe 206 and the exhaust pipe 205. During the processing, the exhaust pipe 205 is closed and the treatment pipe 202 is opened. The high-pressure air pump 201 is turned on regularly to drive the escaped exhaust gas to pass through the treatment pipe 202 and the reflux pipe 102, so that the exhaust gas is filtered through the filter element 203.
[0034] Among them Figure 1 , 2 As shown in Figures 5 and 6, a second support frame 306 is fixedly connected to the bottom edge of the reactor body 3, and the second support frame 306 is connected to the inner side of the anti-leakage tank 1.

[0035] During processing, the stirring motor 303 drives the rotating rod 304 to rotate, which further drives the stirring blade 305 to rotate, so as to stir the raw materials and make the raw materials mixed evenly.
[0036] The specific working principle of the utility model is as follows: before processing, the raw materials are poured into the inner side of the second hopper 204, and the raw materials fall into the reactor body 3 through the third hopper 302 under the action of gravity for processing, the second hopper 204 and the third hopper 302 are closed, the exhaust pipe 205 is opened and the processing pipe 202 is closed, the high-pressure air pump 201 is turned on, and the anti-leakage tank 1 is evacuated to a relative vacuum through the exhaust pipe 206 and the exhaust pipe 205, the exhaust pipe 205 is closed and the processing pipe 202 is opened, and the rotation of the rotating rod 304 is driven by the stirring motor 303, and the rotation of the stirring blade 305 is further driven to stir the raw materials, so that the raw materials are stirred.
