Description

Technical Field

[0001] The present application relates to the field of polycarboxylate water-reducing agent production, and in particular to a cooling device for processing polycarboxylate water-reducing agent. Background Art

[0002] Polycarboxylate water reducer is a high-performance water reducer and also a cement dispersant in cement concrete. It is widely used in highways, bridges, dams, tunnels, high-rise buildings and other projects. This water reducer is green, non-flammable, non-explosive, and can be safely transported by train and car. During its production process, a lot of heat will be generated, so it needs to be actively cooled. The existing cooling equipment is ineffective and cannot dissipate heat efficiently.

[0003] Application No. 202120931774.1 discloses a cooling device for processing polycarboxylic acid water reducer, including a device platform, a cooling tank, an induced draft fan, a feed port, an air outlet pipe, a cyclone separation device, a condenser, a discharge valve, an exhaust pipe and an evaporator, etc. The cooling device provided by the utility model directly discharges low-temperature gas from the polycarboxylic acid water reducer through the exhaust pipe for cooling. The low-temperature gas bulges out numerous tiny bubbles in the polycarboxylic acid water reducer through fine holes. The tiny bubbles are in contact with the polycarboxylic acid water reducer in the process of floating to the liquid surface to exchange heat, thereby taking away a large amount of heat in the polycarboxylic acid water reducer and realizing rapid cooling of the liquid.

[0004] However, in use, there are the following defects:

[0005] Since the device directly recycles the generated hot air, the vaporized water reducer in the hot air will be recycled at the same time, which will cause pollution and difficulty in cleaning in the pipeline and waste of water reducer, affecting the practicality of the device. At the same time, the exhaust pipe is designed to be static. When bubbles are generated, it can only absorb heat from the surrounding water reducer. The heat absorption capacity at a farther distance is poor, affecting the cooling efficiency of the device. Utility Model Content

[0006] The purpose of the present application is to provide a cooling device for processing polycarboxylic acid water-reducing agent, which solves the problem raised in the background technology that since the device directly recycles the generated hot air, vaporized water-reducing agent in the hot air will be recycled at the same time, thereby causing pollution and difficulty in cleaning in the pipeline and waste of water-reducing agent, which affects the practicality of the device. At the same time, the exhaust pipe is designed to be static, and when bubbles are generated, it can only absorb heat from the surrounding water-reducing agent. The heat absorption capacity at a farther position is poor, which affects the cooling efficiency of the device.

[0007] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a cooling device for processing polycarboxylic acid water-reducing agent, comprising a cooling tank, air holes, a motor, a valve and an exhaust box, a partition is fixedly installed on the upper inner wall of the cooling tank, a plurality of air holes are opened on the top of the partition, and absorbent cotton is movably installed on the upper surface of the partition, a motor is embedded and installed in the center of the top of the absorbent cotton, a rotating shaft is fixedly installed on the center of the bottom of the partition, an exhaust pipe is fixedly installed on the bottom of the rotating shaft, the exhaust pipe is connected to the air inlet pipe, an exhaust fan is fixedly installed on the top of the cooling tank, the exhaust fan is connected to the air inlet pipe, and the exhaust fan is connected to the exhaust pipe outside the cooling tank, the bottom of the exhaust pipe is connected to the exhaust box, an air inlet is opened on the left side wall of the exhaust box, and a filter is movably installed inside the exhaust box, and an ice box is movably installed on the bottom of the inner side of the exhaust box.

[0008] In this technical solution, the shaft is driven to rotate by starting the motor, and the exhaust pipe at the bottom of the shaft also rotates with the shaft, so that the coolant in the cooling tank can be stirred, so that the heat dissipation effect can be better. The exhaust holes on the exhaust pipe are all arranged at the bottom, so that bubbles can be generated at the bottom, absorbing heat in the process of rising. With the stirring effect of the shaft and the exhaust pipe, the bubbles can reach various positions in the water reducer, thereby increasing the efficiency of heat absorption and improving the cooling effect of the device. At the same time, by providing a partition, air holes and absorbent cotton, the vaporized water reducer can be absorbed to prevent it from being discharged out of the tank along with the hot air to cause waste and cleaning problems. At the same time, the air drawn in can be filtered through the vacuum box, the filter net and the ice box to filter out dust and impurities, and then the ice box has a cooling effect on the air, so that the air entering the cooling tank can absorb more heat, improve the heat absorption effect, and increase the cooling efficiency of the device. After cooling, it can be discharged through the valve and the discharge pipe.

[0009] As an optional solution of the technical solution of the present application, an exhaust hole is opened at the bottom of the exhaust pipe.

[0010] As an optional solution of the technical solution of the present application, a valve is fixedly installed at the bottom of the cooling tank, and a discharge pipe is connected to the bottom of the valve.

[0011] As an optional solution of the technical solution of the present application, a feed pipe is fixedly connected to the right side wall of the cooling tank.

[0012] As an optional solution of the technical solution of the present application, a hot air pipe is fixedly connected to the upper right side wall of the cooling tank, and a fan is fixedly installed on the inner wall of the hot air pipe.

[0013] As an optional solution of the technical solution of the present application, the rear end of the transmission shaft of the motor is fixedly connected to the rotating shaft.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In the present application, a starting motor drives the shaft to rotate, and the exhaust pipe at the bottom of the shaft also rotates together with the shaft, thereby stirring the coolant in the cooling tank, thereby making the heat dissipation effect better, and the exhaust holes on the exhaust pipe are all arranged at the bottom, so that bubbles can be generated at the bottom, absorbing heat in the process of rising, and with the stirring effect of the shaft and the exhaust pipe, the bubbles can reach various positions in the water reducer, thereby increasing the efficiency of heat absorption and improving the cooling effect of the device.

[0016] 2. The present application is provided with partitions, air holes and absorbent cotton, which can absorb the vaporized water reducer and prevent it from being discharged out of the tank along with the hot air, causing waste and cleaning problems.

[0017] 3. The present application can absorb the vaporized water reducer by providing partitions, air holes and absorbent cotton to prevent it from being discharged out of the tank along with the hot air, causing waste and cleaning problems.
