[0007] The exhaust mechanism includes a negative pressure cylinder, a negative pressure air pump, an air suction port and a pressure sensor.

[0008] As a further preferred embodiment of the present invention, the pouring mechanism includes a stratification port and a sealing plug, the stratification port is arranged on the side wall of the mixing cylinder from top to bottom, the sealing plug is arranged inside the stratification port, and the sealing plug is threadedly connected to the stratification port; the stirring mechanism includes a stirring motor, a stirring shaft and stirring blades, the stirring motor is arranged on the upper wall of the mixing cylinder, the stirring shaft passes through the mixing cylinder and is arranged between the power end of the stirring motor and the inner wall of the bottom of the mixing cylinder, the stirring shaft is rotatably arranged on the inner wall of the bottom of the mixing cylinder, and the stirring blades are arranged on the outside of the stirring shaft.

[0009] When in use, the raw materials for mixing the paint are often mixed into a relatively viscous state in order to maintain their stability and long-term storage performance when leaving the factory. This viscosity is not suitable for direct construction use. It is necessary to mix a variety of raw materials and re-mix them according to construction requirements. Rotate the sealing plug, and the sealing plug is unscrewed from the inside of the stratification port. The raw materials used for mixing the paint are poured into the mixing tube through the stratification port in turn. First, a group of raw materials are poured from the stratification port at the bottom of the mixing tube. When the raw materials poured into the mixing tube from the stratification port at the bottom of the base meet the needs of mixing the paint, stop pouring the raw materials into the mixing tube, and screw the sealing plug into the stratification port at the bottom of the mixing tube. Pour the raw materials for mixing the paint from the stratification port in the middle of the mixing tube. Pour the raw materials into the mixing tube through the stratification port in turn. Due to the relative viscosity of the raw materials, the raw materials are in a state of being placed in layers to avoid premature chemical reactions between the raw materials. At this time, the stirring motor drives the stirring shaft to rotate through the power end, and the stirring shaft stirs and mixes the raw materials in the mixing tube through the stirring blades.

[0010] Preferably, the air compression mechanism includes a fixed ring plate, an air compression spring, a conical plate, a one-way exhaust valve, an air compression magnet, an annular electromagnet, an identification glass and a locking plate bolt. The fixed ring plate is arranged on the top wall of the mixing cylinder outside the stirring shaft, the air compression spring is arranged on the bottom wall of the fixed ring plate outside the stirring shaft, the conical plate is arranged on the bottom wall of the air compression spring outside the stirring motor, multiple groups of the one-way exhaust valves penetrate the upper wall of the conical plate outside the air compression spring, the air compression magnet is arranged on the upper wall of the conical plate outside the one-way exhaust valve, the annular electromagnet is arranged on the outside of the fixed ring plate, multiple groups of the identification glass penetrate the inner wall of the mixing cylinder, the locking plate bolts are symmetrically arranged on the side walls of the mixing cylinder on both sides of the identification glass, and the locking plate bolts are threadedly connected to the mixing cylinder.

[0011] During use, when epoxy floor paint is prepared, volatile organic compounds (VOC) gases will be generated when the solvent evaporates and the epoxy resin reacts with the curing agent. If the VOC gas of the prepared paint exceeds the standard seriously, it needs to be treated as waste. However, if its harmfulness can be reduced by other means, the prepared paint does not need to be treated as waste. At this time, it is necessary to monitor the amount of gas volatilized and the gas composition when the paint is prepared in real time. The harmful gas sensor monitors the harmful gas composition inside the preparation tube in real time through the detection end. In the initial state, the compressed air spring is in an extended state, and the bottom wall of the conical plate and the bottom wall of the identification glass at the bottom of the side wall of the preparation tube are set at the same level, rotating with it. The corresponding locking plate bolt rotates along the mixing cylinder and fits with the side wall of the conical plate, and the locking plate bolt on the upper side wall of the mixing cylinder is rotated. After the locking plate bolt is screwed out of the side wall of the mixing cylinder, a hole is left on the side wall of the mixing cylinder, and the diluent for mixing is injected into the inside through the hole left on the side wall of the mixing cylinder. At this time, the liquid level of the mixing raw material inside the mixing cylinder reaches the position of the identification glass at the bottom of the mixing cylinder and fits with the bottom wall of the conical plate. When more diluent is added to the inside of the mixing cylinder, the liquid level of the raw material rises, and the annular electromagnet is energized to generate magnetism. The annular electromagnet is fixed to the outer side of the fixed ring plate and absorbs the compressed air magnet through magnetic force. The compressed air magnet drives the conical plate to rise to the position of the corresponding identification glass through the deformation of the compressed air spring, and the locking plate bolt is rotated to fix the conical plate.

[0012] The flow direction of the directional control valve is from the collecting pipe to the suction port, the negative pressure air pump extracts the air inside the top of the mixing cylinder through the suction end, the air inside the mixing cylinder enters the negative pressure cylinder through the suction port, and the air inside the negative pressure cylinder is discharged from the exhaust end of the negative pressure air pump. After the air inside the mixing cylinder is discharged, the pressure decreases, and the detection threshold of the pressure sensor is set in advance. The detection threshold of the pressure sensor is slightly lower than the atmospheric pressure. The pressure sensor monitors the gas pressure inside the mixing cylinder through the detection end. When the gas pressure inside the mixing cylinder drops to the detection threshold preset by the pressure sensor, the negative pressure air pump stops extracting the gas inside the mixing cylinder. When the negative pressure air pump is extracting the gas inside the mixing cylinder, the collecting pipe is connected to the negative pressure cylinder through the directional control valve, the outer diameter of the hollow magnetic ball is larger than the inner diameter of the directional control valve, and the hollow magnetic ball is sucked by the negative pressure air pump to the end of the collecting pipe close to the directional control valve. The internal pressure of the collecting pipe on the side of the hollow magnetic ball away from the directional control valve is greater than the pressure on the side of the hollow magnetic ball close to the directional control valve. , using the negative pressure condition inside the mixing cylinder, the hollow magnetic ball is fixed on the side of the directional control valve away from the negative pressure cylinder, and the directional control valve is blocked and cut off by the hollow magnetic ball. On the one hand, the air at the top of the mixing cylinder is discharged to prevent the outside air from interfering with the measurement results of the volatile gas. On the other hand, the volatile gas pushes the hollow magnetic ball to measure the flow of harmful gases released during the mixing of the paint. When the stirring motor mixes the raw materials inside the mixing cylinder through the stirring blades, the raw materials react after mixing with each other, and the generated volatile harmful gases enter the top of the mixing cylinder through the one-way exhaust valve. When the air pressure inside the mixing cylinder is greater than the air pressure inside the collecting tube, the volatile harmful gases push the hollow magnetic ball away from the side wall of the directional control valve, and the hollow magnetic ball uses the gravity of the fall along the collecting tube to extract the volatile gas inside the mixing cylinder. The hollow magnetic ball falls to the corner of the collecting tube and no longer moves. The volatile gas generated when the paint inside the mixing cylinder is mixed does not exceed the standard, and normal mixing operations can be carried out.

[0013] Specifically, a controller is provided on the upper wall of the mixing cylinder.

[0014] Wherein, the controller is electrically connected to the stirring motor, the negative pressure air pump, the pressure sensor, the annular electromagnet, the positioning electromagnet and the harmful gas sensor respectively.

[0015] Preferably, the model of the controller is SYC89C52RC-401.

[0016] The beneficial effects achieved by adopting the above structure are as follows:

[0017] Compared with the prior art, this solution adopts a combination of negative pressure mixing and gas volume collection. Through the provision of a layered mixing mechanism and a negative suction gas measuring mechanism, the flow of harmful gases released during the mixing and blending of raw materials can be monitored in real time under the coordinated use of the pouring mechanism, the stirring mechanism, the exhaust mechanism, the air compression mechanism and the air collection mechanism, so as to avoid the situation in which the prepared coating becomes waste due to excessive harmful gas release. The rising height of the hollow magnetic ball is used to monitor the concentration of harmful gases inside the collection tube. When the rising height of the hollow magnetic ball reaches the height specified by the operator, the operator The harmful gases released from the paint can be reduced by changing the way the raw material ingredients are prepared, ensuring that the prepared paint can be used under low pollution. The volatile gas continuously enters the collection tube through the negative pressure cylinder, and the hollow magnetic ball located at the corner of the collection tube is pushed up by the volatile gas. At this time, the pressure of the volatile harmful gas is relatively large, and its concentration increases with the increase in the height of the hollow magnetic ball. The rising height of the hollow magnetic ball is observed with a ruler. When the hollow magnetic ball rises to the height specified by the operator, the operator reduces the hazard of the prepared paint by adjusting the paint formula ingredients.

[0038] The model of the controller 33 is SYC89C52RC-401.

[0039] When in use, the raw materials used in the preparation of epoxy floor coatings are often prepared into a relatively viscous state in order to maintain their stability and long-term storage performance when leaving the factory. This viscosity is not suitable for direct construction and use. It is necessary to mix a variety of raw materials and re-prepare according to construction requirements, manually rotate the sealing plug 6, the sealing plug 6 is unscrewed from the inside of the stratification port 5, and the raw materials used for preparing the coating are poured into the inside of the preparation tube 2 through the stratification port 5 in turn. First, a group of raw materials are poured into the stratification port 5 at the bottom of the preparation tube 2. When the raw materials poured into the preparation tube 2 from the stratification port 5 at the bottom of the base 1 meet the needs of preparing the coating, stop pouring the raw materials into the preparation tube 2, and the sealing plug 6 is screwed into the stratification port 5 at the bottom of the preparation tube 2. Pour the raw materials for preparing the coating from the stratification port 5 in the middle of the preparation tube 2, and pour the raw materials into the preparation tube 2 through the stratification port 5 in turn. Due to the relative viscosity of the raw materials, the raw materials are in a state of being placed in layers to avoid premature chemical reactions between the raw materials.

[0040] Specifically, when epoxy floor paint is prepared, volatile organic compound (VOC) gas will be generated when the solvent evaporates and the epoxy resin reacts with the curing agent. If the VOC gas of the prepared paint exceeds the standard seriously, it needs to be treated as waste. However, if its harmfulness can be reduced by other means, the prepared paint does not need to be treated as waste. At this time, it is necessary to monitor the amount of gas and gas composition volatilized during paint preparation in real time. The controller 33 controls the harmful gas sensor 37 to start. The harmful gas sensor 37 monitors the harmful gas composition inside the preparation tube 2 in real time through the detection end. In the initial state, the compressed air spring 19 is in an extended state, and the bottom wall of the conical plate 20 and the bottom wall of the identification glass 34 at the bottom of the side wall of the preparation tube 2 are arranged at the same level. The corresponding locking plate bolt 35 is rotated, and the locking plate bolt 35 is rotated along The mixing cylinder 2 rotates to fit the side wall of the conical plate 20, and the locking plate bolt 35 of the upper side wall of the mixing cylinder 2 is rotated. After the locking plate bolt 35 is screwed out of the side wall of the mixing cylinder 2, the side wall of the mixing cylinder 2 has a hole, and the diluent for mixing is injected into the inside through the hole left in the side wall of the mixing cylinder 2. At this time, the liquid level of the mixing raw material in the mixing cylinder 2 reaches the position of the identification glass 34 at the bottom of the mixing cylinder 2 and fits the bottom wall of the conical plate 20. When more diluent needs to be added to the inside of the mixing cylinder 2, the liquid level of the raw material rises, and the controller 33 controls the annular electromagnet 23 to start. The annular electromagnet 23 is energized to generate magnetism. The annular electromagnet 23 is fixed to the outer side of the fixed ring plate 18 and attracts the compressed air magnet 22 through magnetic force. The compressed air magnet 22 is deformed by the compressed air spring 19 to drive the conical plate 20 to rise to the position of the corresponding identification glass 34, and the locking plate bolt 35 is manually rotated to fix the conical plate 20;

[0041] The flow direction of the directional control valve 25 is from the collecting pipe 27 to the suction port 15, the controller 33 controls the negative pressure air pump 14 to start, the negative pressure air pump 14 extracts the air inside the top of the mixing tube 2 through the suction end, the air inside the mixing tube 2 enters the negative pressure tube 13 through the suction port 15, the air inside the negative pressure tube 13 is discharged from the exhaust end of the negative pressure air pump 14, the pressure inside the mixing tube 2 is reduced after the air is discharged, the detection threshold of the pressure sensor 16 is pre-set, the detection threshold of the pressure sensor 16 is slightly lower than the atmospheric pressure, the controller 33 controls the pressure sensor 16 to start, the pressure sensor 16 monitors the gas pressure inside the mixing tube 2 through the detection end, when the gas pressure inside the mixing tube 2 drops to the detection threshold pre-set by the pressure sensor 16, the controller 33 controls the negative pressure air pump 14 to stop extracting the gas inside the mixing tube 2, the negative pressure air pump 14 When extracting the gas inside the mixing cylinder 2, the collecting tube 27 is connected to the negative pressure cylinder 13 through the directional control valve 25, the outer diameter of the hollow magnetic ball 28 is larger than the inner diameter of the directional control valve 25, and the hollow magnetic ball 28 is sucked by the negative pressure air pump 14 to the end of the collecting tube 27 close to the directional control valve 25, and the internal pressure of the collecting tube 27 on the side of the hollow magnetic ball 28 away from the directional control valve 25 is greater than the pressure on the side of the hollow magnetic ball 28 close to the directional control valve 25. By utilizing the negative pressure condition inside the mixing cylinder 2, the hollow magnetic ball 28 is fixed on the side of the directional control valve 25 away from the negative pressure cylinder 13, and the directional control valve 25 is blocked and cut off by the hollow magnetic ball 28. On the one hand, the air at the top of the mixing cylinder 2 is discharged to prevent the outside air from interfering with the measurement result of the volatile gas. On the other hand, the volatile gas pushes the hollow magnetic ball 28, so that the flow rate of harmful gases released during the coating mixing process can be measured.

[0042] The controller 33 controls the stirring motor 8 to start, and the stirring motor 8 drives the stirring shaft 9 to rotate through the power end. The stirring shaft 9 stirs and mixes the raw materials inside the mixing cylinder 2 through the stirring blades 10. In the process of mixing the raw materials inside the mixing cylinder 2 through the stirring blades 10, the raw materials are mixed and reacted with each other, and the generated volatile harmful gas enters the top of the mixing cylinder 2 through the one-way exhaust valve 21. When the air pressure inside the mixing cylinder 2 is greater than the air pressure inside the collecting tube 27, the volatile harmful gas pushes the hollow magnetic ball 28 away. The hollow magnetic ball 28 on the side wall of the directional control valve 25 uses the gravity of the fall along the collection tube 27 to extract the volatile gas inside the mixing tube 2. The hollow magnetic ball 28 falls to the corner of the collection tube 27 and no longer moves. At this time, the harmful gas sensor 37 monitors the harmful gas content inside the mixing tube 2. If the harmful gas concentration inside the mixing tube 2 monitored by the harmful gas sensor 37 does not reach the specified value of the operator, the volatile gas generated during the mixing of the paint inside the mixing tube 2 does not exceed the standard, and the paint mixing operation can be carried out normally.

[0043] When volatile gases are continuously generated during the paint mixing process, the gas pressure inside the mixing tube 2 increases, and the volatile gases continuously enter the collecting tube 27 through the negative pressure tube 13. The hollow magnetic ball 28 located at the corner of the collecting tube 27 is pushed up by the volatile gases. At this time, the pressure of the volatile harmful gases is relatively large, and their concentration increases with the increase in the height of the hollow magnetic ball 28. By observing the concentration of the harmful gases inside the mixing tube 2 monitored by the harmful gas sensor 37, when the concentration of the harmful gases inside the mixing tube 2 monitored by the harmful gas sensor 37 reaches the height specified by the operator, the operator The staff can reduce the harmfulness of the prepared paint by adjusting the paint formula ingredients, avoid the continuous increase in the concentration of harmful gases, and ensure that the prepared paint will not be discarded. The staff can observe the rising height of the hollow magnetic ball 28 through the scale 36 to determine the flow rate of harmful gases released by the prepared paint inside the mixing tube 2. The measured release amount of harmful gases can be used to provide guidance for the construction of the prepared paint. Understanding the release amount of harmful gases during the preparation process can help the staff to formulate a reasonable construction ventilation plan, reduce the accumulation of harmful gases at the construction site, and reduce the impact on the health of the construction staff.

[0044] After the paint is stirred and mixed, the flow direction of the directional control valve 25 is changed. At this time, the flow direction of the directional control valve 25 is from the air extraction port 15 to the inside of the collecting tube 27. The harmful gas with a high concentration inside the collecting tube 27 cannot flow back. The sealing plug 6 is rotated, and the sealing plug 6 is screwed out from the inside of the stratification port 5. The mixed paint in the mixing tube 2 flows out, and then the sealing plug 6 is screwed into the inside of the stratification port 5. The mixing tube 2 is in a sealed state, and the flow direction of the directional control valve 25 is changed. , rotate the locking plate bolt 35, the locking plate bolt 35 rotates along the mixing cylinder 2 away from the side wall of the conical plate 20, the annular electromagnet 23 attracts the compressed air magnet 22 by magnetic force, the compressed air magnet 22 drives the conical plate 20 to rise by the deformation of the compressed air spring 19, and the conical plate 20 squeezes the volatile harmful gas at the top of the mixing cylinder 2 into the negative pressure cylinder 13 through the suction port 15, the controller 33 controls the reverse direction of the negative pressure air pump 14, and the negative pressure air pump 14 injects external air into the negative pressure cylinder 13 through the suction end. The positioning electromagnet 29 is energized to generate magnetism. The positioning electromagnet 29 and the directional control valve 25 are arranged with opposite poles. The positioning electromagnet 29 adsorbs the hollow magnetic ball 28 by magnetic force. The hollow magnetic ball 28 is fixed to the side wall of the filter cartridge 30. The inner diameter of the filter cartridge 30 is larger than the outer diameter of the hollow magnetic ball 28. The harmful gas inside the collection tube 27 is discharged after being filtered by the activated carbon adsorption layer 32. When the harmful gas components inside the mixing cartridge 2 monitored by the harmful gas sensor 37 disappear, the positioning electromagnet 29 is powered off and demagnetized. Since the end of the filter cartridge 30 close to the collection tube 27 is conical, the hollow magnetic ball 28 falls to the corner of the collection tube 27 for placement, thereby completing the detection operation of the harmful gas flow released during the coating mixing process, avoiding the generation of waste, and improving the efficiency of coating mixing. The above operation can be repeated the next time it is used.
