A latex reactor with automatic cleaning function

Abstract

This utility model discloses a latex reactor with an automatic cleaning function, relating to the field of reactors. The reactor includes a reactor body and a water storage tank, with a rinsing mechanism installed on the top surface of the water storage tank. The rinsing mechanism includes a water pump, a delivery pipe, and rinsing components. The water pump is fixedly installed on the top surface of the water storage tank. Through the rinsing mechanism and heat exchange copper pipe, this utility model utilizes the high-heat organic waste gas generated after the latex reaction. This gas is transported to the protective outer shell through a flue pipe. The water pump is turned on to deliver water from the water storage tank to the heat exchange copper pipe for heat exchange, using the recovered heat to heat the water. When cleaning the reactor body, the diversion pipe valve is closed, and the delivery pipe valve is opened to deliver hot water to the rinsing components to rinse the reactor body. This avoids the problem of residual latex hardening and solidifying after rinsing with low-temperature water, which is difficult to clean. Furthermore, using recovered heat to heat the water is more energy-efficient.

Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, and in particular to a latex reaction vessel with an automatic cleaning function. Background Technology

[0002] A latex reactor is a piece of equipment used for emulsion polymerization reactions, widely applied in the production of chemical products such as latex, rubber latex, and emulsion polymers. Its main function is to conduct emulsion polymerization reactions within the reactor by controlling conditions such as temperature, pressure, and stirring rate to produce the desired latex product. After the reaction, latex tends to remain on the inner wall of the reactor. This residual latex gradually hardens and coagulates, forming difficult-to-remove scale that affects its use.

[0003] Traditional cleaning of latex reactors often relies on rinsing the inside of the reactor with water. However, when the water temperature is low, the latex will harden and coagulate upon contact with the latex residue, making cleaning more difficult. In addition, some latex residues with strong adhesion are also difficult to remove completely, affecting the cleaning effect.

[0004] Therefore, a latex reactor with an automatic cleaning function was proposed. Utility Model Content

[0005] This utility model provides a latex reactor with an automatic cleaning function, which has the advantages of avoiding the hardening and coagulation of residual latex after rinsing with water at low temperatures, resulting in better cleaning effect and avoiding residue. This solves the problem that when the water source temperature is low, contact with latex residue will cause the latex to harden and coagulate, increasing the difficulty of cleaning, and even the latex residue with strong adhesion is difficult to clean completely.

[0006] To achieve better cleaning results and avoid residue buildup caused by hardening and coagulation of residual latex after rinsing with low-temperature water, this utility model provides the following technical solution: A latex reactor with automatic cleaning function, comprising a reactor body and a water storage tank, a rinsing mechanism disposed on the top surface of the water storage tank, the rinsing mechanism comprising a water pump, a delivery pipe and a rinsing assembly, the water pump being fixedly installed on the top surface of the water storage tank, one end of the delivery pipe being connected to the output end of the water pump, and one end of the rinsing assembly being connected to the delivery pipe; a diversion pipe disposed on the surface of the delivery pipe, one end of the diversion pipe being connected to a heat exchange copper pipe for heating the water source in the water storage tank; a reactor cover disposed on the top surface of the reactor body, a servo motor being fixedly installed on the top surface of the reactor cover, a deep cleaning mechanism being fixedly installed at the output end of the servo motor, the deep cleaning mechanism comprising a stirring shaft, a brush holder and a scraper holder, the stirring shaft being fixedly installed at the output end of the servo motor, the brush holder being fixedly installed on one side of the surface of the stirring shaft, and the scraper holder being fixedly installed on the other side of the surface of the stirring shaft.

[0009] As a preferred embodiment of this utility model, a protective shell is fixedly installed on the surface of the heat exchange copper tube, and a sealing plate is fixedly installed on one side of the protective shell. The protective shell is used to protect the heat exchange copper tube.

[0010] As a preferred technical solution of this utility model, one side of the top surface of the vessel lid is connected to a flue gas pipe for discharging high-heat flue gas from inside the reactor body, and one end of the flue gas pipe is connected to the inside of the protective shell. The flue gas pipe is used to transport organic waste gas.

[0013] As a preferred embodiment of this utility model, valves are fixedly installed on the surfaces of the conveying pipe and the diversion pipe.

[0014] Compared with the prior art, the present invention provides a latex reactor with an automatic cleaning function, which has the following advantages:

[0015] This latex reactor features an automatic cleaning function.

[0016] With the setup of the rinsing mechanism and heat exchange copper tubes, the latex reaction produces high-heat organic waste gas, which is transported to the protective shell through the flue gas pipe. The water pump is turned on to transport water from the storage tank to the heat exchange copper tubes for heat exchange. The recovered heat is used to heat the water source. When cleaning the reactor body, the diversion pipe valve is closed and the delivery pipe valve is opened to transport hot water to the rinsing assembly to rinse the reactor body.

The scraper scrapes off the latex with strong adhesion and hardness from the inner wall of the reactor, while the brush brushes the inner wall of the reactor. Combined with hot water rinsing, this makes the reactor body cleaner and avoids residue. Attached Figure Description

[0040] The working principle and usage process of this utility model are as follows: First, the raw materials are put into the reaction vessel 1 for reaction. After the heating element 13 is powered on, it heats the latex raw materials in the reaction vessel 1. The servo motor 7 drives the stirring shaft 81 to rotate to assist in mixing the raw materials.

[0041] Afterwards, the organic waste gas is transported to the protective shell 10 through the flue pipe 11, the valve of the diversion pipe 4 is opened, the valve of the delivery pipe 32 is closed, the water pump 31 draws water from the water storage tank 2 and transports it to the heat exchange copper pipe 5 through the diversion pipe 4, absorbing the heat of the organic waste gas and heating the water.

[0042] After waiting for the latex reaction to be accepted, the valve of the diversion pipe 4 is closed and the valve of the delivery pipe 32 is opened. The water pump 31 delivers the hot water in the water storage tank 2 to the annular water pipe 331 through the delivery pipe 32, and then rinses the inside of the reaction vessel 1 through multiple spray nozzles 332.

The water pump 31 draws water from the water storage tank 2, and the water is transported through the copper pipe diversion pipe 4 to the heat exchange copper pipe 5, where the heat from the organic waste gas is absorbed, thus purifying the water. After heating and waiting for the latex to react, the valve of the diversion pipe 4 is closed and the valve of the delivery pipe 32 is opened. The water pump 31 delivers the hot water in the water storage tank 2 to the annular water pipe 331 through the delivery pipe 32. Then, the inside of the reactor body 1 is rinsed through multiple spray nozzles 332. At the same time as rinsing, the servo motor 7 drives the deep cleaning mechanism 8 to rotate. The scraper frame 83 scrapes off the latex with strong adhesion and hardness on the inner wall of the reactor body 1, and the brush frame 82 brushes the inner wall of the reactor body 1.
