Description

Technical Field

[0001] The utility model belongs to the technical field of reaction kettles, in particular to a temperature-controlled stirring kettle for preparing a self-leveling penetrating crystallization waterproof coating. Background Art

[0002] Penetrating crystallization waterproof coating is an active substance with a molecular structure of active silicon. It has a small molecular weight and contains both hydrophobic and hydrophilic groups. Its hydrophilicity is greater than its hydrophobicity. It is soluble in water. It does not undergo polycondensation and crystallization in a dry environment, but undergoes polycondensation and crystallization in a humid environment. It is mainly composed of a mixture of active silicon, cement, and active inorganic mixtures. It is used as the core raw material for cement-based penetrating crystallization waterproof coating. During the processing of penetrating crystallization waterproof coating, a stirring kettle is usually required to stir a variety of raw materials. The stirring kettle 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 in the same way as the performance principle of the reactor to ensure the stability of the quality of the finished product. However, it still has the following disadvantages in actual use:

[0003] 1. The utility model with the publication number CN217774138U discloses a temperature-controlled reactor for the production of waterproof coatings, wherein an inner reactor is arranged inside the outer reactor, a feeding hopper is arranged on the top of the outer reactor, a first discharge port is arranged at the bottom of the inner reactor, a second discharge port is arranged at the bottom of the outer reactor, a stirring component and a pressure relief component are arranged inside the inner reactor, a temperature regulating component acting on the raw materials of the inner reactor is arranged inside the outer reactor, a display screen and a controller are arranged on the outer reactor, the first solenoid valve, the stirring component, the temperature regulating component and the display screen are electrically connected to the controller respectively, and when the reactor controls the temperature of the raw materials, the outer surface of the reactor is usually cooled to further cool the raw materials, but the contact area between the material and the inner wall of the reactor is limited, if the stirring mechanism does not stir, the material near the center of the reactor is difficult to cool down quickly, and if the stirring mechanism continues to stir, while the material is cooled, the friction between the stirring mechanism and the material will cause the material to heat up, thereby reducing the temperature control efficiency;

[0004] 2. When the temperature-controlled stirring kettle is stirring the materials, the material will often cause the air pressure in the stirring kettle to continue to rise during the reaction temperature rise process. In order to ensure the safety of the stirring kettle, it is usually necessary to use a pressure relief component to relieve the pressure of the stirring kettle. However, when the air pressure in the stirring kettle is high, the temperature inside the stirring kettle is usually high, and the temperature difference between the inside and outside of the stirring kettle is large. When relieving pressure, a large amount of heat may be discharged through the pressure relief component, reducing the temperature control efficiency of the material. Utility Model Content

[0005] The utility model aims to provide a temperature-controlled stirring kettle prepared with a self-leveling penetrating crystallization waterproof coating. The utility model solves the problem that, when the temperature-controlled stirring kettle is actually used, the contact area between the material and the outer shell of the low-temperature reactor is limited, and the friction between the material and the stirring mechanism during the stirring process will cause the material to heat up. When the pressure is relieved through the pressure relief component, due to the large temperature difference between the inside and outside of the reactor, part of the heat will be lost during the pressure relief process, further affecting the temperature control efficiency.

[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 temperature-controlled stirring kettle prepared with a self-leveling penetrating crystallization waterproof coating, comprising an insulation outer barrel, an insulation top cover, a stirring barrel and a temperature-controlled cover, wherein the insulation outer barrel is clamped and fixed with the insulation top cover on the top, a plurality of ventilation stirring blades are arranged at the bottom of the insulation top cover, each ventilation stirring blade is penetrated and clamped with an air outlet one-way valve on the outer side, a stirring barrel is inserted into the inner side of the insulation outer barrel, a temperature-controlled cover is clamped and fixed with the top of the stirring barrel, a second exhaust pipe is penetrated and clamped with the top of the temperature-controlled cover, an air pump is clamped and fixed with the top of the temperature-controlled cover, and a temperature-controlled pipe is penetrated and clamped with one end of the outer peripheral surface of the air pump;

[0008] When the material needs to be cooled or heated, low-temperature or high-temperature gas is pumped into the material through the gas outlet one-way valve to exchange heat between the material and the gas, thereby avoiding direct temperature control of the outer wall of the stirring kettle, uneven cooling or heating of the material, and the gas will exchange heat with the ventilation stirring blades before heat exchange with the material, thereby avoiding heating of the material due to friction between the stirring mechanism and the material. After the air pressure in the stirring barrel rises to a threshold value, the air pressure in the heat-insulating outer barrel and the stirring barrel can be balanced by opening the second exhaust pipe, and the pressure in the stirring barrel can be reduced. At the same time, the heat-insulating outer barrel has a heat-insulating effect on the stirring barrel. The temperature in the heat-insulating outer barrel is higher than the ambient temperature, thereby avoiding a large loss of heat. After the pressure in the stirring barrel is reduced, the pressure in the heat-insulating outer barrel is reduced again, thereby avoiding a large loss of heat when the pressure in the stirring barrel is relieved.

[0009] Furthermore, a stirring motor is clamped and fixed on the top of the insulation cover, a first exhaust pipe is welded through the top of the insulation cover, a rotating tube is clamped on the bottom of the stirring motor, the rotating tube is inserted through the top of the insulation cover, a vent is opened through the top of the outer circumference of the rotating tube, and the ventilation stirring blade is welded through the outer circumference of the rotating tube;

[0010] The stirring motor can drive the rotation of the rotating tube and the ventilation stirring blades to stir the materials in the stirring barrel, thereby improving the automation degree of the stirring kettle. The gas cools down the ventilation stirring blades through the rotating tube, and performs heat exchange on the ventilation stirring blades, thereby avoiding the material heating caused by the friction between the stirring mechanism and the material. The air is discharged into the stirring barrel through the air outlet one-way valve, contacts with the material, and performs heat exchange on the material, thereby avoiding direct temperature control of the outer wall of the stirring kettle, and avoiding the cooling or uneven heating of the material.

[0011] Furthermore, a through hole is opened in the center of the bottom of the thermal insulation outer barrel, a heat insulation support frame is clamped and fixed to the edge of the bottom of the thermal insulation outer barrel, and the first exhaust pipe is connected to the inside of the thermal insulation outer barrel;

[0012] The mixing barrel can be insulated by the insulating outer barrel to avoid heat exchange between the surface of the mixing barrel and the environment during material heating, thereby ensuring the temperature control efficiency of the material. During pressure relief, when the air pressure in the insulating outer barrel is relatively high, the pressure in the insulating outer barrel can be relieved by opening the first exhaust pipe to avoid a small difference in air pressure between the insulating outer barrel and the mixing barrel, which results in the gas in the mixing barrel being unable to be discharged into the insulating outer barrel.

[0013] Furthermore, a hopper is welded through the bottom of the mixing barrel, a discharge pipe is welded through the bottom of the hopper, a support base is clamped and fixed to the edge of the bottom of the hopper, the support base is attached to the bottom of the insulation outer barrel, and the discharge pipe is clamped through the top of the through hole;

[0014] When the mixing barrel is mixing materials, the ventilated stirring blades can scrape off the materials adhering to the inner wall of the mixing barrel to avoid waste of raw materials. The supporting base can avoid direct contact between the mixing barrel and the insulation outer barrel, thereby improving the insulation effect of the insulation outer barrel on the mixing barrel.

[0015] Furthermore, an exhaust pipe is inserted through one end of the air pump, the bottom of the exhaust pipe is inserted through the top of the temperature control cover, a feed pipe is welded through the top of the temperature control cover, and the feed pipe is inserted through the bottom of the insulation cover;

[0016] After the air pressure in the mixing barrel rises to a threshold value, the second exhaust pipe can be opened to balance the air pressure in the insulated outer barrel and the mixing barrel, thereby reducing the pressure in the mixing barrel. At the same time, the insulated outer barrel has an insulating effect on the mixing barrel. The temperature in the insulated outer barrel is higher than the ambient temperature, thereby avoiding a large amount of heat loss.

[0017] Further, the outer circumference of the temperature control tube is welded and fixed with heat dissipation fins, the outer circumference of the temperature control tube is clamped and fixed with a condenser tube, the heat dissipation fins are located on the inner side of the condenser tube, the two ends of the outer circumference of the condenser tube are respectively penetrated and welded with a water inlet pipe and a drain pipe, a heating tube is clamped and fixed inside the temperature control tube, one end of the temperature control tube is penetrated and welded with a limit frame, the limit frame is located at the other end of the temperature control tube relative to the air pump, the limit frame is penetrated and clamped on the outer circumference of the rotating tube, the vent is penetrated and connected with the inner side of the limit frame, and the water inlet pipe and the drain pipe are both penetrated and clamped on the outer circumference of the insulation outer barrel;

[0018] When the material is heated, the air pump pumps the gas into the temperature control tube, heats the gas through the heating tube, and further pumps the gas into the material through the gas outlet one-way valve to exchange heat with the material to heat the material. When the material needs to be cooled, cold water is pumped into the condenser through the water inlet pipe, which can further cool the gas in the temperature control tube, pump cold air into the material to cool the material, thereby avoiding direct temperature control of the outer wall of the stirring kettle and uneven cooling or heating of the material.

[0019] The utility model has the following beneficial effects:

[0020] 1. The utility model solves the problem that when the reactor controls the temperature of the raw materials, the outer surface of the reactor is usually cooled to further cool the raw materials, but the contact area between the materials and the inner wall of the reactor is limited. If the stirring mechanism does not stir, the materials near the center of the reactor are difficult to cool down quickly. If the stirring mechanism continues to stir, the friction between the stirring mechanism and the materials while cooling the materials will cause the materials to heat up, thereby reducing the temperature control efficiency. When the materials are heated or cooled, the heated or cooled gas is pumped into the rotating tube by an air pump, and then pumped into the ventilation stirring blades, and further discharged into the materials through the air outlet one-way valve, so that the gas and the materials exchange heat, thereby avoiding direct temperature control of the outer wall of the stirring kettle, and the material cooling or uneven heating. Moreover, the gas exchanges heat with the ventilation stirring blades before exchanging heat with the materials, thereby avoiding the material heating up due to the friction between the stirring mechanism and the materials.

[0021] 2. The utility model solves the problem that when a temperature-controlled stirring kettle is used to stir materials, the materials often cause the air pressure in the stirring kettle to continue to rise during the process of reaction and heating. In order to ensure the safety of the stirring kettle, it is usually necessary to use a pressure relief component to relieve the pressure of the stirring kettle. However, when the air pressure in the stirring kettle is relatively high, the temperature inside the stirring kettle is usually also relatively high, and the temperature difference between the inside and outside of the stirring kettle is relatively large. When the pressure is relieved, a large amount of heat may be discharged through the pressure relief component, thereby reducing the temperature control efficiency of the materials. When the pressure is relieved in the stirring barrel, the second exhaust pipe is opened to balance the air pressure in the heat-insulating outer barrel and the stirring barrel, and the pressure in the stirring barrel is reduced. At the same time, the heat-insulating outer barrel has a heat-insulating effect on the stirring barrel. The temperature in the heat-insulating outer barrel is higher than the ambient temperature, thereby avoiding a large amount of heat loss. After the pressure in the stirring barrel is reduced, the pressure in the heat-insulating outer barrel is reduced again, thereby avoiding a large amount of heat loss in the stirring barrel when the pressure is relieved.
