Detailed Description

As shown in fig. 1 to 3, a dust removing system of a plasma cutter includes a dust hood 2 fixed to a plasma cutter 1, the dust hood 2 sealing a cutter frame of the plasma cutter 1 inside. A dust collection trolley 4 moving along with the cutting machine frame is arranged in the dust collection cover 2, a first dust collection opening 41 and a second dust collection opening 42 are formed in the side edge of the dust collection trolley 4, and the first dust collection opening 41 is communicated with an air inlet cover 5 fixed at the top of the dust collection cover 2 through a dust collection pipeline.

A ventilation groove 3 is arranged below the dust collection trolley 4, and the ventilation groove 3 is paved along the direction of the movement track of the plasma cutting machine 1. In the process that the dust collection trolley 4 moves along with the cutting machine frame, an air inlet of the ventilation groove 3 is opened, and dust absorbed by the dust collection trolley 4 is sent into the ventilation groove 3 through the opened air inlet of the ventilation groove 3. Then the ventilation groove 3 is communicated with the dust remover 6 through an air pipe, the dust outlet of the dust remover 6 is communicated with the air inlet of the induced draft fan 7, and the air outlet of the induced draft fan 7 is communicated with the exhaust pipe 8.

Under the action of a ventilator, dust-containing gas enters the dust collection trolley 4 through the air inlet cover 5 and the second dust collection opening 42, the air inlet cover 5 and the second dust collection opening 42 are respectively positioned at the upper part and the lower part of the dust collection cover 2, dust in the dust collection cover 2 is completely sucked into the dust collection trolley 4, then the dust is introduced into the dust remover 6 through the ventilation groove 3, and the dust-removed gas is discharged out of a workshop through the exhaust pipe 8 through the induced draft fan 7.

The general working process of the present utility model is described in the above embodiment, but the specific connection manner of the dust collection cart 4 and the ventilation slot 3 is not limited, and in order that those skilled in the art can better understand the working process of the present utility model, the structures of the dust collection cart 4 and the ventilation slot 3 and the connection relationship of the two are specifically disclosed in the present embodiment as shown in fig. 5.

As shown in fig. 6-7, the dust collection trolley 4 is in a box structure with an opening at the bottom, two upper rollers 43 are arranged at the top of the box at intervals, two lower rollers 44 are arranged at the bottom of the box, and the first dust collection opening 41 and the second dust collection opening 42 are arranged on the side edges of the box side by side.

As shown in fig. 8, an air inlet channel is pre-arranged at the top of the ventilation groove 3 and is arranged along the length direction of the ventilation groove 3, and an adhesive tape 31 is laid above the air inlet channel. In practice, the conventional carrier tape 31 is selected to satisfy the sealing property and flexibility. The adhesive tape 31 bypasses the lower roller 44 and the upper roller 43 of the box body, and the dust collection trolley 4 moves along with the cutter frame to drive the adhesive tape 31 to be separated from the air inlet channel.

The top of ventilation groove 3 passes through the sealed air inlet channel of sticky tape 31, and sticky tape 31 is taken on the roller, and the in-process that dust absorption dolly 4 removed can separate sticky tape 31 and air inlet channel, and the opening and the air inlet channel intercommunication of dust absorption dolly 4 below just so the air that contains the dust has got into ventilation groove 3 inside from dust absorption dolly 4. Therefore, not only can the dust be transferred from the dust collection trolley 4 to the ventilation groove 3 be completed, but also the tightness of paper pieces of the dust collection trolley 4 and the ventilation groove 3 can be ensured.

In addition, in order to conveniently support the adhesive tape 31, a plurality of support bars 32 are provided at lateral intervals on the air inlet passage. The support bar 32 serves both as a support and facilitates the tight covering of the adhesive tape 31.

On the basis of the above embodiment, in order to further improve the sealing performance of the dust hood 2, the arrangement of the sealant plate 23 is added in this embodiment, and the specific arrangement is as follows:

The dust hood 2 comprises a frame structure 21, a sealing plate is arranged on the outer side of the frame structure 21, a maintenance door 22 is arranged on the sealing plate, a sealing rubber plate 23 is arranged at the bottom of the frame structure 21, and the bottom surface of the sealing rubber plate 23 is lapped on the upper surface of a workpiece 9 to be cut.

In the process of moving the steel plate to be cut forward, the sealing rubber plate 23 is always in contact with the steel plate to be cut, so that dust is prevented from dispersing out from a gap between the sealing rubber plate and the steel plate to be cut. And the dust collected at the lower portion of the dust hood 2 is directly sucked into the dust cart through the second dust suction port 42.

Under the action of the ventilator, dust-containing gas is sucked by the dust hood 2 and enters the dust trolley, the ventilation groove 3, the dust remover 6 and the ventilator through the air pipe to be discharged into the atmosphere. When the dust producing process equipment moves, the dust trolley moves in parallel along with the dust producing process equipment under the action of the equipment. When the dust trolley moves to a new position, the position of the vent hole formed on the upper surface of the vent groove 3 is correspondingly changed, and dust-containing gas enters the vent hole at the new position to complete the flow conversion from the moving trolley to the vent groove 3. The required air quantity is small, the dust removal efficiency is high, the implementation is convenient, and the cost is low.

The embodiments of the present utility model have been described in detail with reference to the accompanying drawings, but the present utility model is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the spirit of the present utility model.
