Description

Barrel top plate sintered filter

The utility model relates to a filter net, in particular to a plate type sintered filter screen, which is a filter barrel in a powder conveying production line and is installed above the filter barrel, which can reduce the volume of the filter barrel and effectively filter the barrel. No dust will accumulate.

At present, the filter has a wide application range and plays an important role in the raw material production line, especially for the production and transportation of raw materials of dust particles. In the process of transportation, a filter drum containing a filter screen is required, and the filter screen is placed in the filter. There are many types of barrels. The existing filter screen is shown in FIG. 4, and the filter screen 80 is disposed in the filter barrel 90. The filter barrel 90 is provided with an air suction pipe 96 at the upper end and a dust collector 98 at the lower end. The filter screen 80 is a porous wave plate filter material. The plurality of filter screens 80 are vertically disposed in the filter bucket 90. The gap between the filter screen 80 and the filter screen 80 faces the gate hole 92 of the filter bucket 90. The hole 92 is openably provided with a gate 94. Since the plurality of screens 80 are vertically arranged in the filter barrel 90, the required volume of the filter barrel 90 is large, and the filter barrel 90 is relatively occupied by space. Generally, the backwashing line is installed between the screen 80 and the suction pipe 96. The screen 80 is not easily cleaned by backwashing and the dust is easily caught on the net.

The purpose of the novel is to reduce the space occupied by the filter in the filter bucket, thereby reducing the volume of the filter bucket, and another purpose is to make the dust difficult to get stuck on the filter screen, and the filter screen does not need to be washed and washed.

In order to achieve the above object, the present invention provides a barrel top plate type sintered filter screen which is disposed at the top end of the filter barrel main body. The barrel top plate type sintered filter screen comprises a frame and a screen body, and the frame is surrounded by a surrounding plate. Forming a hollow portion; the filter net system is disposed in a hollow portion of the frame and is a sintered porous wave plate material, wherein the filter net body is a waveform of a fixed interval, and an end edge of the filter net body is coupled to the surrounding plate The inner surface.

The barrel top plate type sintered filter screen has a card portion extending horizontally outwardly from the end edge of the plate, and the card portion has a plurality of pin holes arranged at equal intervals.

The barrel top plate type sintered filter screen has a circular shape.

By the above technical means, at least the effect achieved by the present invention is as follows: 1. Since the barrel top plate type sintered filter screen is installed on the top of the filter barrel, there is no problem that a large number of screens are vertically arranged in the filter barrel and require a large space. Therefore, the volume of the filter bucket can be reduced without occupying space, and the dust is not easily flying due to the increase of the space inside the filter bucket. 2. Because the barrel top plate type sintered filter is easy to backwash, the dust is not easily caught on the net, which increases convenience and cleanliness.

The preferred embodiment of the present invention is to provide a frame 20 and a screen body 30. The preferred embodiment of the present invention relates to a top of a filter drum. Referring to FIG. 1 to FIG. 3, the top plate sintered screen 10 includes a frame 20 and a screen body 30. The barrel top plate sintered screen 10 may be circular. The frame 20 is surrounded by a surrounding plate 22 to form a hollow portion. The upper end edge of the surrounding plate 22 extends horizontally outwardly from a locking portion 24, and the locking portion 24 has a plurality of portions. The plug holes 242 are equally arranged in a ring shape; the screen body 30 is disposed in the surrounding plate 22 of the frame 20 and is a sintered porous wave plate material, and the filter body 30 is a fixed wave shape, and the uneven structure is designed. The surface area of the absorption can be increased, and the end edge 302 of the screen body 30 is bonded to the inner surface 222 of the panel 22.

For the assembly and use of the present invention, please refer to FIG. 3 , which is described as follows: 1. The barrel top plate sintered filter screen 10 is horizontally disposed at the top end of the filter barrel 40 , and can be fixed to the filter barrel 40 through a plurality of bolt holes 242 by using a plurality of bolts 242 . An air suction pipe 50 is connected to the top of the top of the filter drum 40, and a backwashing line connecting the gas storage barrel and the pulse valve is disposed between the top plate sintered filter screen 10 and the suction pipe 50. 52, the backwashing line 52 is a disk having a plurality of holes below, a suction nozzle 60 is disposed at a distance from the filter screen 40 on the peripheral surface of the filter drum 40, and a dust collector is connected below the filter bucket 40. 70. 2. When the raw material dusts A and B are conveyed, the blower rotates to inhale the suction pipe 50, and the dust A, B and air enter the filter drum 40 from the suction nozzle 60, and the dust A, B and air will The filter drum 40 is first rotated downwards and upwards. The dust A-based particles are heavy and fall down to the dust collector 70. The dust B-based particles are light and float, and even float to the top of the barrel. Sintering the screen 10. 3. Backwashing the barrel top plate type sintering filter 10, controlling the pulse valve speed to cause the gas in the gas storage barrel to be ejected, the gas is flushed to the backwashing line 52 and then rushed through the hole of the backwashing line 52, and the gas finally collides with the filter body. 30, the dust B is instantaneously dropped into the dust collector 70.

With the above structure of the preferred embodiment of the present invention, at least the achievable effects of the preferred embodiment of the present invention are as follows: 1. The barrel top plate sintered screen 10 is horizontally disposed at the top end of the filter barrel 40 and the barrel top plate type sintering filter The thickness of the net 10 is thin, and the filter drum 40 can be disposed without a large space for matching the plurality of barrel top plate sintered screens 10 vertically, and the volume of the filter barrel 40 can be effectively reduced, and the space inside the filter barrel 40 is increased. The whirlwind is weakened and the dust is not easy to fly. 2. Since the backwash line 52 is horizontally disposed above the screen body 30, the gas can completely collide with the screen body 30 through the holes of the backwash line 52 and the backwash line 52, so the screen body 30 can be cleaned. Therefore, the dust A, B is not easy to be stuck on the net, and the barrel top plate sintered filter 10 does not need to be washed and washed to increase convenience and cleanliness.
