Problems solved by technology

[0002] The melting and casting furnace is a casting equipment made according to the melting process. During the working process, the melting and casting furnace will generate a large amount of smoke. In order to reduce pollution, it is necessary to remove dust from the melting and casting furnace. The rear end of the filter is equipped with dust collectors such as bag filter or electrostatic precipitator. In actual use, the filter sometimes becomes clogged, which affects the work of the entire dust removal device. People have been studying how to solve this problem.

Embodiment 1

[0030] Embodiment 1, the present invention provides a kind of casting furnace dedusting device, see figure 1 , comprising a housing 1, one end of the housing is provided with an air inlet 2, the other end of the housing is provided with an air outlet 3, and a filter 9 is arranged inside the housing; the top of the filter is fixed with a second An elastic body 4, the bottom end of the filter screen is fixed with a second elastic body 5, in this embodiment, the first elastic body and the second elastic body can be rubber sheets or silica gel sheets, the first elastic body The elastic body is connected with the top surface of the housing, the second elastic body is connected with the bottom surface of the housing, the air inlet is provided with a first block 6 and a second block 7, and the second The stopper can move up and down; the bottom surface of the first stopper is inclined, and the height of one end close to the filter screen is smaller than the height of the other end; t...

Embodiment 2

[0034] Embodiment 2, embodiment 2 is an optimized deformation of embodiment 1, the structure is roughly the same as that of embodiment 1, the difference is that the first block can be set to move up and down, as figure 2 Shown is the state where the first block is adjusted upwards and the second block is adjusted to the bottom. This structure can adjust the ratio of the inflow of inclined wind to the inflow of horizontal wind and the entry positions of inclined wind and horizontal wind by adjusting the positions of the first stopper and the second stopper, so that the filter screen can Tilting in different directions is more conducive to the removal of pollutants from the filter.

[0035] In this embodiment, when the first stopper and the second stopper are installed, the two sides of the first stopper and the second stopper can be slidably connected to the side wall of the corresponding air inlet; A first driving device for driving the first block to move up and down and a ...

Embodiment 3

[0037] Embodiment 3, embodiment 3 is a modification of embodiment 1, the structure is roughly the same as that of embodiment 1, the difference is that 3 stoppers are set on the air inlet, specifically, see Image 6 , the air inlet is provided with a third block 10, a fourth block 11 and a fifth block 12, the third block and the fifth block can move up and down; the fourth block The bottom surface and the top surface are inclined, so that the fourth block forms an isosceles triangle or an isosceles trapezoidal shape; wherein, the inclination direction of the bottom surface of the fourth block is: the height of one end close to the filter screen is smaller than that of the other end. the height of one end. The top surface of the fifth stopper matches the bottom surface of the fourth stopper, so that the top surface of the fifth stopper can coincide with the bottom surface of the fourth stopper after contacting, that is, the first The top surface of the fifth block is inclined, ...

Abstract

The invention relates to a dust removal device for a melting and casting furnace, comprising a housing, one end of the housing is provided with an air inlet, the other end of the housing is provided with an air outlet, and a filter screen is provided inside the housing; the top end of the filter screen is A first elastic body is fixed, a second elastic body is fixed at the bottom end of the filter, the first elastic body is connected to the top surface of the housing, and the second elastic body is connected to the bottom surface of the housing. connect. The dust removal device for melting and casting furnace provided by the present invention fixes the elastic body on the top and bottom of the filter screen, so that the elastic body deforms when the shell enters the wind, and the filter screen can move to the right end, especially when the filter screen is blocked. The resistance to the air intake becomes larger and the movement is more obvious. When the wind force decreases or stops, the elastic body drives the filter to move to the original position. During the left and right movement, the pollutants attached to the filter are more likely to fall off, thereby reducing Clogging of the filter.
