Description

Technical Field

[0001] The utility model relates to the technical field of alumina evaporators, and more specifically, to a large-area anti-blocking device for a distribution plate. Background Art

[0002] Alumina evaporator is a thermal device that utilizes the high temperature stability and chemical inertness of the material. It is usually made of alumina. Alumina is a high melting point metal oxide that is resistant to high temperatures and has good chemical inertness. Therefore, it is very suitable for use as a heating and evaporation device in high temperature environments. The working principle of the alumina evaporator is to place the liquid to be evaporated in the evaporation pool on the alumina surface, and evaporate the liquid into gas by heating or increasing the gas pressure in the cavity.

[0003] During the operation of the alumina evaporator, due to the high temperature, high pressure and high concentration of the first-effect evaporator, scars are easily formed and attached to the inner wall of the shell. If these scars are not removed in time, they will fall off when they reach a certain thickness. In addition, there will be debris falling during maintenance. The fallen large pieces of scars or debris will be transported to the distribution plate and heating pipe mouth at the top of the evaporator through the circulation pump, causing large-scale blockage, affecting the heat exchange efficiency of the evaporator, and may even damage the equipment. Therefore, it is necessary to design a large-area anti-blocking device for the distribution plate. Utility Model Content

[0012] Beneficial effects of the utility model:

[0013] The filter screen cylinder of the filter pipe section is filtered and separated by the filter screen cylinder in the filter pipe section, which will not cause large-scale blockage of the subsequent distribution plate.

The top of the shell is located above the distribution disk 1 and is connected to a feed pipe 2. The end of the feed pipe 2 is located outside the shell and is connected to a circulation pump. An anti-clogging mechanism is provided between the liquid inlet end of the circulation pump and the end of the outlet pipe 10. The anti-clogging mechanism includes a tee a3 connected to the liquid inlet end of the circulation pump, and a tee b9 is connected to the side of the end of the outlet pipe 10 close to the tee a3.

[0023] As attached Figure 1-4As shown, both ends of the filter pipe section 6 are provided with flange blind plates 14, and the edges of the flange blind plates 14 are annularly and equidistantly provided with several connecting holes 15 for bolt connection. The two ends of the filter pipe section 6 are fixedly connected to the ends of the first connecting pipe 4 and the second connecting pipe 7 by bolts on the flange, and a sealing ring is provided at the connection.

[0024] Working principle: This utility model is designed with a large area anti-blocking device for the cloth plate. The specific structure is as shown in the attached manual. Figure 1-4 As shown, in the present technical solution, the anti-clogging mechanism is designed with separate pipe sections that do not affect each other when in use. When the evaporator is working, the solution carries scabs and debris through the anti-clogging mechanism and is filtered and separated by the filter pipe section 6. The scabs and debris are filtered and separated in the filter cylinder 11 in the filter pipe section 6, and the solution is filtered through the filter cylinder 11 and reaches the circulation pump inlet for circulation operation. Among them, the filter pipe section 6 is convenient to disassemble. After disassembly, the internal filter cylinder 11 can be quickly taken out and cleaned. When cleaning is required, since the anti-clogging mechanism adopts a separate pipe section design, it is only necessary to close the first valve 5 and the second valve 8 on one side, and then remove the bolts on the flange blind plate 14 to disassemble and clean the filter pipe section 6. The first valve 5 and the second valve 8 on the other side are not closed, so that the entire anti-clogging mechanism can still continue to work without affecting normal filtering use. Therefore, when the filter pipe section 6 needs to be disassembled and cleaned, there is no need to shut down the machine.
