Detailed Description

The present application is described in further detail below with reference to the attached drawings.

Referring to fig. 1, a negative pressure type dust settling workshop disclosed in the embodiment of the present application is mainly composed of a working chamber 11, a support 12, a grid 13, an air duct 14, a buffer chamber 15, a fan 16, and the like, wherein a main portion of the workshop is the working chamber 11, the working chamber 11 is similar to a room, and can provide a working space for polishing and other work for workers, and the working space can play a certain limiting role to prevent generated flying dust from scattering into the surrounding environment.

A plurality of racks 12 are placed on the bottom surface of the working chamber 11, and generally, the racks 12 are arranged in a matrix of MxN, M and N being natural numbers, on which it is convenient to lay a grating 13. The number of the grating 13 is one or more, and is sequentially arranged on the support 12 on the bottom surface of the working chamber 11 to form a plane.

It should be understood that the material of the grid 13 is generally two types, i.e., iron and glass fiber reinforced plastic, the iron grid 13 is generally welded by using steel strips, and the glass fiber reinforced plastic grid 13 is made by mixing glass fiber and resin in a mold, so that the holes of the grid 13 are generally rectangular or square.

The air duct 14 is located outside the working chamber 11, one end of the air duct is connected with the working chamber 11, the other end of the air duct is connected with the buffer chamber 15, and the buffer chamber 15 is also connected with the fan 16, namely the working chamber 11, the air duct 14, the buffer chamber 15 and the fan 16 are connected in sequence.

During operation, the fan 16 first draws out air from the buffer chamber 15 to reduce the pressure in the buffer chamber 15, at which time the air in the air duct 14 flows into the buffer chamber 15 and the air in the working chamber 11 flows into the air duct 14. The connection between the air duct 14 and the cabin 11 is located below the grille 13, so that the air in the cabin 11 will first flow below the grille 13 and then flow out of the air duct 14.

It will be appreciated that the dust generated during sanding is small and light in weight, is airborne and is only brownian with the air and is difficult to remove by precipitation, so that when air flows in the cabin 11, the dust can flow with the air flow.

When the worker works in the workshop 11, the fan 16 is started simultaneously, air in the workshop 11 is pumped out through the air pipe 14 and the buffer chamber 15, and most of air in the workshop 11 flows to the lower part of the grille 13 firstly and then flows out through the air pipe 14 because the joint of the air pipe 14 and the workshop 11 is positioned below the grille 13.

In this process, the dust in the working room 11 flows out simultaneously with the flowing air.

It should be understood that because the raise dust is produced constantly, the fan 16 is in continuous operation during the polishing process, and simultaneously, in order to improve the dust removal effect, one or more air ducts can be placed on the bottom surface of the workshop 11, and the air ducts are provided with air ports which can face the side surface or the top surface of the workshop 11, so that the distribution uniformity of the air flowing in the workshop 11 can be effectively improved, and the dust removal effect is further improved.

Referring to fig. 3, as a possible implementation manner provided in the negative pressure type dust suppression workshop of the present application, a water storage area 32 is disposed in the buffer chamber 15, the water storage area 32 is filled with water, and when the raised dust in the buffer chamber 15 contacts with the water, the raised dust will be deposited in the water, thereby facilitating subsequent collection and treatment.

Referring to fig. 1, as a possible embodiment provided in the negative pressure type dust settling workshop of the present application, a filter device 2 is installed at a connection position of a fan 16 and a buffer chamber 15, and the filter device 2 is used for intercepting dust flowing out from inner ears of a workshop 11 in the buffer chamber 15.

The volume of the buffer chamber 15 is larger than that of the air pipe 14, so that the flow rate of air flowing into the inner ear of the buffer chamber 15 from the air pipe 14 is reduced rapidly, the flow rate of corresponding raised dust is also reduced, a part of the raised dust is deposited on the bottom surface of the buffer chamber 15 in the slow flowing process, but a part of the raised dust still flows out from the fan 16, and therefore, a filter device 2 is arranged at the connection position of the fan 16 and the buffer chamber 15, and the raised dust is completely intercepted in the buffer chamber 15.

Referring to fig. 2 and 3, the filter device 2 has the following forms:

in a first form: the filtering device 2 consists of a connecting pipe 21 and a filter element 22, the two ends of the connecting pipe 21 are respectively connected with the buffer chamber 15 and the fan 16 by flanges, and the filter element 22 is plugged in the connecting pipe 21. When air containing dust flows through the filter element 22, the dust is intercepted by the filter element 22.

In a second form: the filtering device 2 is composed of an outer frame 23 and a filtering cloth 24, the outer frame 23 is in bolt connection with the buffer chamber 15 and the fan 16, the filtering cloth 24 is adhered to the outer frame 23 through glue or sewn on the outer frame 23 through threads, and when air containing dust flows through the filtering cloth 24, the dust can be intercepted by the filtering cloth 24.

As a possible implementation manner provided by the negative pressure type dust suppression workshop of the present application, in a direction away from a joint of the air pipe 14 and the operation room 11, the aperture on the grille 13 tends to decrease, that is, several grills with different inner hole specifications need to be used in one operation room 11, an inner hole on the grille close to the joint of the air pipe 14 and the operation room 11 is small, and an inner hole on the grille far from the joint of the air pipe 14 and the operation room 11 is large.

Because the air pressure near the connection between the air pipe 14 and the working chamber 11 is significantly lower than that at other places in consideration of the actual distribution of the pressure, the air flow rate at that place is higher, and in order to make the distribution of the air flow rate more uniform, the size of the inner hole on the grille 13 at that place is reduced, so that the air flow rate distribution in the working chamber 11 is more uniform.

Referring to fig. 1, as a possible embodiment provided in the negative pressure type dust settling workshop of the present application, a cover plate 31 is disposed on the grille 13, and the cover plate 31 can cover the inner hole of the grille 13, because in some cases, the space in the working room 11 is not required to be used completely, and after the cover plate 31 is used to cover these areas, the air flow rate of other areas can be increased, so that the dust settling effect of other areas is better.

The embodiments of the present invention are preferred embodiments of the present application, and the scope of protection of the present application is not limited by the embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
