Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of polycarboxylic acid water-reducing agent production, and specifically relates to a polycarboxylic acid water-reducing agent compounding production line with a defoaming function. Background Art
[0002] In the polycarboxylate water-reducing agent compounding production line, the neutralization reaction stage is the stage that needs to be defoamed. In the neutralization reaction, due to the heat release of the reaction, the reaction materials produce a lot of foam, and industrial water is needed to cool down and suppress the foam. This is to prevent the foam from being too intense and affecting the reaction process.
[0003] At present, a certain amount of defoamer is generally added to the liquid to eliminate the foam generated during the compounding process, but the addition of defoamer will affect the performance of polycarboxylic acid water reducer. The defoamer is installed in the neutralization reaction tank to defoam, as a defoaming method that does not affect the performance of polycarboxylic acid water reducer;
[0004] However, when this type of defoamer is currently in use, since the defoaming chamber on the defoamer is located at the top of the inner chamber of the neutralization reaction tank and the installation position of the defoamer is fixed, it cannot be adjusted according to the height of the liquid level of the mixed liquid in the neutralization reaction tank. When facing a low liquid level ratio reaction, there are still many foams that cannot be sucked into the defoaming chamber due to distance reasons. Even after the material in the neutralization reaction tank is discharged, foam still remains in the tank. Utility Model Content
[0005] In order to make up for the deficiencies of the prior art, the utility model proposes a polycarboxylic acid water-reducing agent compounding production line with a defoaming function.
[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0007] A polycarboxylate water-reducing agent compounding production line with a defoaming function, comprising a neutralization reaction tank arranged on the polycarboxylate water-reducing agent compounding production line, wherein a bracket is arranged on the top of the neutralization reaction tank, and a height-adjustable defoamer is arranged on the bracket;
[0008] The defoamer is installed on a moving platform of a screw linear module set on the top of the bracket. The motor on the screw linear module drives the screw to rotate and drives the moving platform to move up and down, thereby adjusting the height position of the defoamer in the neutralization reaction tank.
[0009] The height position of the defoamer in the reaction tank is adjustable through the action of the lead screw linear module. The defoamer can be adjusted according to the liquid level height of the mixed liquid in the neutralization reaction tank so as to better suck out the foam and eliminate them.
[0010] Preferably, the defoamer includes an inverted U-shaped plate, a motor fixedly mounted on the inverted U-shaped plate, a transmission shaft having one end fixedly connected to an output end of the motor and the other end fixedly connected to a crushing impeller in the defoaming chamber, and a suction port arranged at the bottom end of the defoaming chamber.
[0011] Preferably, the top of the defoaming chamber is fixedly connected to the vertical insert cylinder through a support rod, and the vertical insert cylinder is fixed to the bottom of the inverted U-shaped plate and cooperates with and intersects with the tank cover of the neutralization reaction tank.
[0012] Preferably, the transmission shaft rotates and penetrates the vertical insert cylinder.
[0013] Preferably, during the lifting and lowering movement of the defoamer, the inverted U-shaped plate is always located above the neutralization reaction tank.
[0014] The motor is located at the top of the neutralization reaction tank and has no direct contact with the mixture of polycarboxylate water reducer. , and the safety performance is better.
[0015] Preferably, the aperture of the suction port gradually decreases from the defoaming chamber toward the foam, so as to avoid foam backflow and blockage.
[0016] Preferably, a bucket-shaped cover is fixedly provided on the bottom side of the inverted U-shaped plate, and bearing seats rotatably connected to the transmission shaft are arranged at equal distances on the bucket-shaped cover, which can enhance the stability and pressure resistance of the transmission shaft and the crushing impeller, and ensure the normal operation of the defoamer.
[0017] Compared with the prior art, the technical effects and advantages of the utility model are:
[0018] The defoamer in the polycarboxylate water-reducing agent compounding production line with defoaming function is installed on the bracket, and its height position is adjusted by the lifting movement of the screw linear module. In this way, the defoamer can be adjusted according to the liquid level of the mixed liquid in the neutralization reaction tank to better suck out the foam and eliminate them. By adjusting the height position of the defoamer, it can be ensured that the defoamer can always effectively suck out the foam, regardless of whether the liquid level is low or high. This can avoid the foam remaining in the neutralization reaction tank and ensure the smooth progress of the neutralization reaction process;
[0019] Driven by the motor of the screw linear module, the defoamer can be quickly and accurately adjusted to the appropriate height to meet the foam elimination needs of different liquid level heights. The transmission shaft drives the crushing impeller to rotate, and the foam entering the defoaming chamber is crushed to make it easier to eliminate. The aperture of the suction port gradually decreases from the center to the edge, which helps to capture and extract fine foam, improve the defoaming efficiency, and prevent foam overflow. The setting of the bucket cover and the bearing seat enhances the stability of the defoamer structure, ensuring that it can withstand pressure when the transmission shaft and the crushing impeller rotate, and ensuring the long-term stable operation of the defoamer.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] The following is combined with Figure 1-3 To further explain this application in detail,
[0026] The embodiment of the present application discloses a polycarboxylate water-reducing agent compounding production line with a defoaming function, comprising a neutralization reaction tank 1 arranged on the polycarboxylate water-reducing agent compounding production line, a bracket 2 is arranged on the top of the neutralization reaction tank 1, and a height-adjustable defoamer 3 is arranged on the bracket 2;
[0027] The defoamer 3 is installed on the moving platform 5 of the screw linear module 4 set on the top of the bracket 2. The motor 7 on the screw linear module 4 drives the screw to rotate and drives the moving platform 5 to move up and down, thereby adjusting the height position of the defoamer 3 in the neutralization reaction tank 1.
[0028] The height position of the defoamer 3 in the reaction tank is adjustable through the action of the screw linear module 4. The defoamer 3 can be adjusted according to the liquid level height of the mixed liquid in the neutralization reaction tank 1 so as to better suck out the foam and eliminate them.
[0029] The defoamer 3 includes an inverted U-shaped plate 6, a motor 7 fixedly mounted on the inverted U-shaped plate 6, a transmission shaft 9 having one end fixedly connected to the output end of the motor 7 and the other end fixedly connected to the crushing impeller in the defoaming chamber 8, and a suction port 10 arranged at the bottom end of the defoaming chamber 8.
[0030] The top of the defoaming chamber 8 is fixedly connected to a vertical insert tube 12 via a support rod 11 . The vertical insert tube 12 is fixed to the bottom of the inverted U-shaped plate 6 and is matched and inserted with the tank cover of the neutralization reaction tank 1 .
[0031] The transmission shaft 9 rotates and penetrates the vertical insert cylinder 12 .
[0032] First, the top of the defoaming chamber 8 is fixedly connected to the vertical insert cylinder 12 through the support rod 11. The vertical insert cylinder 12 is fixed to the bottom of the inverted U-shaped plate 6 and is inserted in cooperation with the tank cover of the neutralization reaction tank 1. The motor 7 on the screw linear module 4 drives the screw to rotate, driving the moving platform 5 to move up and down, and the vertical insert cylinder 12 is inserted in cooperation with the neutralization reaction tank 1. The motor 7 is started and drives the transmission shaft 9 to rotate. The transmission shaft 9 rotates through the vertical insert cylinder 12 to drive the crushing blades to rotate to crush the foam sucked from the defoaming chamber 8 through the suction port 10.
[0033] During the lifting and lowering movement of the defoamer 3 , the inverted U-shaped plate 6 is always located above the neutralization reaction tank 1 .
[0034] The motor 7 is located at the top of the neutralization reaction tank 1 and has no direct contact with the mixture of the polycarboxylate water-reducing agent. , and the safety performance is better.
[0035] The aperture of the suction port 10 gradually decreases from the defoaming chamber 8 toward the direction of the foam. Since the size of the suction port 10 gradually decreases from the center to the edge, it can capture and extract fine bubbles more effectively. These fine bubbles are often more difficult to remove because they are more easily carried away by the liquid. When the foam is sucked into the smaller suction port 10, the centrifugal force will increase due to the reduction in the diameter of the suction port 10. This helps to separate the gas and liquid faster when the foam leaves the suction port 10. The smaller diameter of the suction port 10 helps to break the foam due to high-speed flow when it leaves the suction port 10. In this way, the foam will become smaller and easier to separate. If the suction port 10 is too large, it may cause the foam to overflow, thereby reducing the defoaming effect. The smaller suction port 10 helps to prevent this from happening.
[0036] A bucket-shaped cover 13 is fixedly provided on the bottom side of the inverted U-shaped plate 6, and bearing seats 14 rotatably connected to the transmission shaft 9 are arranged at equal distances on the bucket-shaped cover 13. The stability and pressure resistance of the rotation of the transmission shaft 9 and the crushing impeller can be enhanced to ensure the normal operation of the defoamer 3.
[0037] When the liquid level in the neutralization reaction tank 1 is low, the defoaming chamber 8 can be lowered to an appropriate height to better suck out the foam and eliminate them. When the liquid level rises, the defoaming chamber 8 can be raised accordingly to ensure that the foam can always be effectively sucked out. By designing a defoamer 3 with adjustable height, the foam generated in the neutralization reaction stage of the polycarboxylate water-reducing agent compounding production line can be effectively eliminated while ensuring that the performance of the polycarboxylate water-reducing agent is not affected.
[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
