Description

[Detailed Description of the Invention] This invention relates to a ceramic filter for a powder transport tank car, and more particularly to an improvement in a ceramic filter used as a filter for pumping powder fluid in a powder transport tank car.

Recently, powder and granular materials such as cement, sugar, and flour have been filled into tank cars and transported overland to their destinations. At the destination, compressed air is supplied into the tank and the pressure is used to discharge the powder and granules from the tank.

The above-mentioned compressed air can be obtained by stopping the fuel supply to four cylinders and using half of the engine as a compressor when the engine of the tank car is, for example, a V-8 cylinder. In this case, gasoline or heavy oil was originally combusted, so the compressed air supplied from it contains fine particles of gasoline or heavy oil, or moisture. Therefore, various devices for passing the compressed air have been proposed.

However, the filters used in conventional filtration devices have low efficiency in capturing carbon contained in the compressed air, and their performance is not perfect.
There were problems such as not being able to use it repeatedly.

As a result of study, the inventors of the present invention found that the above-mentioned filter has an extremely high efficiency in capturing carbon, etc. contained in the compressed air, and has an excellent performance, and also burns the captured carbon, etc. by heating. It has been found that it is sufficient to use a filter made of ceramic, which can be easily reused by drying the filter.

The present invention was made based on the above-mentioned knowledge, and uses a highly efficient ceramic filter, which is easy to disassemble and assemble, and can burn carbon etc. frequently, so it can always maintain cleanliness. It is an object of the present invention to provide a ceramic filter for a powder tank car that can be used repeatedly over a long period of time and has low overresistance.

In other words, the present invention integrally molds a ceramic cylindrical overchamber with one side open and the other side closed into a honeycomb structure so that the open side and closed side form a staggered shape with respect to the axial end face, and The gist of this invention is a ceramic filter for a tank car for transporting powder and granular materials, which is fitted in a filter case that is symmetrically divided into two parts at the center.

Hereinafter, the present invention will be explained in detail by way of examples with reference to the drawings.

Fig. 1 is a sectional front view showing a ceramic filter for a tank car for transporting powder and granular materials according to an embodiment of the present invention, Fig. 2 is a left side view of the same, and Fig. 3 is a sectional view taken along the - line in Fig. 1. be.

In the figure, E is a ceramic filter for a tank car for transporting powder and granular materials, which is an embodiment of the present invention.
A cylindrical overchamber 1 made of ceramic with one side a open and the other side b closed and having a polygonal cross section is integrated into a honeycomb structure such that the open side a and the closed side b are staggered with each other on the axial end surface. It is constructed by molding. Therefore, this ceramic filter E is
A large number of cylindrical overchambers 1 made of ceramic are arranged with their axes coincident with each other, and the opening side a and the closing side b are arranged in a staggered manner.

Next, the structure of the filter case 10 to which the present ceramic filter E is attached will be explained with reference to FIG.

The filter case 10 is composed of a pair of left and right filter case members 10a and 10b, which are symmetrically divided into two parts at the central part in the axial direction, and connecting parts 12a and 12b are provided on the peripheral edges of each opposing end of the divided part. These left and right filter case members 10a, 1
Holding members 13a and 13b are provided on the inner surface of Ob so as to hold the circumferential surfaces of both left and right end surfaces Ea and Eb of the ceramic filter E in the axial direction from the left and right sides, respectively.

Reference numeral 30 denotes a heat-resistant sealing material, which has a wall thickness that can seal the gap D formed between the inner circumferential surface of the filter case 10 and the outer circumferential surface of the ceramic filter E, on the outer circumferential surface near both sides in the axial direction of the ceramic filter E. It is wrapped thickly so that As the heat-resistant sealing material, a material having heat resistance, sealing properties, and buffering properties, such as silicone rubber or asbestos, is used, so that a sealing effect and a buffering effect can be obtained at the same time.

Furthermore, the clamping members 13a, 13b are made by welding the base of the iron plate to a predetermined position on the inner surface of each filter member 10a, 10b, and attaching heat-resistant and shock-absorbing materials such as wire mesh, springs, asbestos, and glass wool to the supporting side of the ceramic filter E. The buffer members 14a and 14b are each bonded to each other.

In this embodiment, the mounting parts 11a and 11b provided on both sides of the filter case 10 are formed of flanges, as shown in FIG. It is drilled at the same time.

Furthermore, each filter case member 10a, 10
The connecting portion 12 provided on the periphery of the opposite end side of b
In this embodiment, a and 12b are composed of flanges as shown in FIG. 4, and when connecting each filter case member 10a and 10b, bolt holes are bored at intervals on the circumferential surface of the flange. It is fastened by a connecting member, that is, a bolt or a nut.

As described above, the present invention has a cylindrical overchamber made of ceramic with one side open and the other side closed and having a polygonal cross section, and has a honeycomb structure in which the open side and the closed side form a staggered shape with respect to each other on the axial end surface. Because it is integrally molded into a filter case and is fitted into a filter case that is symmetrically divided into two parts at the center in the axial direction, the overefficiency of fine particles is high, and it is easy to disassemble and assemble, allowing for frequent combustion of carbon, etc. It can always be kept clean and can be used repeatedly over a long period of time. The ceramic filter of the present invention has a large overarea, which together with the fact that the fluid flow is uniflow, can reduce overresistance.

In particular, the ceramic filter of the present invention has two cylindrical ceramic filtration chambers arranged symmetrically in the center in the axial direction.
Because it was fitted into a divided filter case, it was disassembled and
It is easy to assemble and can burn carbon etc. frequently to keep it clean at all times. In addition, since the filter casing is symmetrically divided into two parts at the center in the axial direction, it is inexpensive to manufacture and can be used without distinguishing between the parts where it is used.

Therefore, the ceramic filter of the present invention is suitable as a filter for cleaning compressed air for powder transport vehicles.
