Abstract

This creation discloses a drying device, which is composed of an air compressor, a pressure dividing valve, a pressurizing motor, a sewage tank, and a filter tank. The air compressor outputs high-pressure gas to the partial pressure valve, which provides a pressurizing motor to operate through the partial pressure valve, and the pressurizing motor sucks the sludge in the sewage tank and sends it to the filter tank for filtration. The partial pressure valve can be used to filter the filter tank. High-pressure gas is input to complete the sludge drying and cake removal steps; thereby, the sludge (water) is dehydrated and dried, which in turn contributes to the reduction of transportation costs and facilitates subsequent processing operations.

Description

Sludge drying device

This creation is related to a drying device, especially a device for dewatering and drying sludge (water).

According to the fact that due to the development of industry, the environmental pollution of sludge is becoming more and more serious, such as general civilian sludge, fluorine-based wastewater sludge from the semiconductor industry and photovoltaic industry, arsenic-based wastewater sludge discharged from chemical vapor deposition processes, and metal basic The metal-containing wastewater sludge of the industrial surface treatment industry, the inorganic particle coagulated sludge of the coagulation sedimentation treatment, etc.; in order to achieve the treatment or reuse value of the aforementioned sludge, the sludge needs to be dewatered to form a sludge cake. Depending on the type of sludge, it can be used for burial, valuable fuel, compost, and building materials recycling.

In the traditional technical field, most of the sludge (water) treatment is through the sludge dewatering machine to form a sludge cake by high-pressure squeezing and dehydration. With the current sludge treatment method, the sludge cake still has about The moisture content of 70~90%, and the current transportation cost of sludge disposal and disposal, the transportation and treatment costs are calculated by weight. Such a high moisture content will increase the cost of disposal, transportation and disposal. In addition, the sludge cake with high moisture content will drip and pollute urban roads during the transportation and treatment of the sludge cake with high moisture content, and it is easy to cause the problem of secondary pollution due to the decomposition of the sludge cake. Furthermore, the sludge with high moisture content has a high weight In addition, the volume is relatively large, and both the storage space and the transportation process cause waste of space costs and operational difficulties for the processing industry.

The reason is that, in view of this, the creator of this case has many years of rich experience in design, development and actual production in the relevant industry. There are imperfections in the above-mentioned sludge (water) treatment field, and he deeply feels the need for improvement. His experience in the design and manufacture of such products has been researched and improved. After a long period of conceptual experimentation and correction, he has designed this creation to achieve a more ideal effect.

The main purpose of this creation is to improve the conventional sludge (water) dehydration and drying process, and then provide a sludge drying device, so that it can effectively dehydrate and dry the sludge (water), and then help It is helpful to reduce the transportation cost and facilitate subsequent processing operations.

In order to achieve the above purpose, the specific means of this case is: a drying device, including an air compressor, a pressure divider valve, a pressurizing motor, a sewage tank, and a filter tank. The air compressor outputs high-pressure gas to the partial pressure valve, which provides a pressurizing motor to operate through the partial pressure valve, and the pressurizing motor sucks the sludge in the sewage tank and sends it to the filter tank for filtration. A filter cartridge is arranged inside the filter tank. The filter cartridge defines the first space and the second space; the sludge enters the first space in the filter tank through the inlet under the filter tank in a high-pressure conveying manner, and then is discharged from the outlet pipe above the second space. High-pressure gas is input to the filter tank through the partial pressure valve to complete the sludge drying and cake removal steps; thereby, it can achieve the creative purpose.

Please refer to the structure diagram of the sewage tank shown in FIG. 2. The sewage tank 40 is loaded with sludge (water) to be treated. The bottom of the tank is provided with an outlet and is connected with the dip tube 32 of the pressurizing motor 30.

Please refer to the structure diagram of the filter tank shown in FIG. 3. The filter tank 50 is a tank with a filter tube 51 inside. The surface of the filter tube 51 is provided with a filter layer of appropriate mesh size. The filter tube 51 is installed When inside the filter tank 50, there is no gap between the top and bottom ends, and defines a first space A outside the filter cylinder 51 and a second space B inside the filter cylinder 51; a feed inlet 52 is provided under the filter tank 50, The port of the inlet 52 is located in the first space A of the filter tank 50 and is connected to the delivery pipe 33 of the pressurizing motor 30. A water outlet pipe 53 and a first gas delivery pipe 54 are provided above the filter tank 50. The water outlet pipe 53 and the first gas delivery pipe 54 extend to the second space B in the filter tank 50, and the other end of the first gas delivery pipe 54 is connected to the second gas valve 24 of the partial pressure valve 20; There is a second gas delivery pipe 55, one end of the second gas delivery pipe 55 extends to the first space A in the filter tank 50, and the other end is connected to the third gas valve 25 of the partial pressure valve 20.

Because the second space B is compressed by high pressure, the air can only escape from the filter cartridge 51 quickly to the first space A to be discharged. When the gas passes through the surface of the filter cartridge 51 from the inside to the outside, it also blows off the sludge attached to the surface of the filter cartridge 51 to remove the cake. When the dried sludge detached from the surface of the filter cartridge 51 falls on the bottom of the filter tank 50, it can be borrowed The valve is opened by the pneumatic butterfly valve 56 so that the dried sludge falls from the bottom of the filter tank 50 and is collected.
