Description

filter press drum Technical Field

[0001] The present invention relates to the field of machinery, in particular to a filter press drum. Background Art

[0002] Green mountains and clear waters are invaluable assets. What pollutes the environment is the equipment problems in the field of solid-liquid separation. A large number of chemical companies have been shut down and merged because of substandard solid-liquid separation equipment. Solid-liquid separation equipment is a panacea for basic industries and is used in all walks of life. Now, as long as we talk about environmental protection, we are talking about filter presses. Flocculants and coagulants can be used in environmental protection. Various flocculants and coagulants cannot be added to materials in production, so they cannot be treated well. Moreover, the cost of adding flocculants and coagulants to sewage treatment is too high, and money has to be invested in environmental protection. The wastewater is pumped underground through deep wells, causing serious groundwater pollution.

[0003] Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a filter press drum in view of the above problems.

[0005] In order to solve the above technical problems, the technical solution provided by the present invention is: a filter press drum includes a sealing cover, which is respectively arranged at both ends of the drum, with through holes provided on the sealing cover, a cylinder body provided between the sealing covers, a filter chamber provided on the cylinder body, a drainage port provided at the center of the filter chamber, the drainage ports are evenly spaced at the bottom of the filter chamber, air ports are provided at both ends of the bottom of the filter chamber, a partition is provided between the filter chambers, and an axis head is provided at the center of the sealing cover.

[0006] As an improvement, a filter press plate is installed in the filter chamber to achieve solid-liquid separation by pressurizing the filter press plate. The pressurization process is achieved by mechanical pressurization and negative pressure in the filter chamber.

[0007] As an improvement, a number of through holes are arranged in a circular array on the cover, which reduces the overall weight without reducing the strength of the material, making it more energy-efficient when in use.

[0008] As an improvement, the filter chambers are arranged in a circular array on the barrel, and the filter chambers are directly fixed on the barrel. The circular array method can ensure that a complete set of filtration operations can be completed when the barrel rotates.

[0009] The advantages of the present invention compared with the existing technology are: compared with the traditional filter press residue processing method, it adopts a more efficient mechanized operation, and can be remotely controlled and intelligently operated for toxic and harmful materials, especially materials containing radioactive elements, which is very convenient, saves a lot of filtration time, saves manpower, thereby reducing operating costs, and has good market prospects.

[0014] The present invention will be described in further detail below with reference to the accompanying drawings.

[0015] In a specific implementation of the present invention, the filter press drum includes a cover 1, which is arranged at both ends of the drum, with a through hole 2 provided on the cover 1, a cylinder body 3 provided between the cover 1, a filter chamber 4 provided on the cylinder body 3, a drainage port 5 provided at the center of the filter chamber 4, and the drainage ports 5 are evenly spaced at the bottom of the filter chamber 4. Air ports 6 are provided at both ends of the bottom of the filter chamber 4, a partition 7 is provided between the filter chambers 3, and a shaft head 8 is provided at the center of the cover.

[0016] As an improvement, a filter press plate is installed in the filter chamber 3 to achieve solid-liquid separation by pressurizing the filter press plate. The pressurization process is achieved by mechanical pressurization and negative pressure in the filter chamber.

[0017] As an improvement, a number of through holes 2 are arranged in a circular array on the cover 1, thereby reducing the overall weight without reducing the strength of the material, making it more energy-efficient when in use.

[0018] As an improvement, the filter chambers 4 are arranged in a circular array on the cylinder body 3, and the filter chambers are directly fixed to the cylinder body. The circular array method can ensure that a complete set of filtration operations can be completed when the cylinder body rotates.

[0019] Working principle of the present invention: The continuous filter press currently applied for invention is conceptually different from various existing filter presses. The slurry operates in a sealed and enclosed shell with a circumference of 360°. The shell applied for this time increases the volume ratio. The first step of solid-liquid separation is achieved by pump pressure and vacuum suction in the cavity of at least 230° within the circumference. The thickness of the filter cake is changed within the range of 60°. The filter cake is squeezed from thick to thin. The vacuum is always in the last 40° of suction to squeeze the filter cake into a drum with 0 contact with the shell. The moisture content of the filter cake is further squeezed dry. The vacuum suction stops within the circumference of 330°, and the backflush air is connected just at the discharge port. The filter cake is automatically lifted off and enters the automatic washing area of ​​the filter cloth after being lifted off, and it operates continuously over and over again. Due to the low moisture content of the filter cake, it can be automatically discharged as long as the solid content reaches more than 3%. It is placed in the sedimentation tank for concentration without the need to add flocculants and coagulants, which will not change the properties of the material and reduce enterprise costs.
