Description

Dust collection pipeline and dust collector

Technical Field

The utility model relates to the technical field of dust collection, in particular to a dust collection pipeline and a dust collector.

Background

At present, when punching a PCB, a laser drilling machine is usually collected for operation, and the principle is that materials to be removed are changed into dust through a high-energy laser beam, and the dust is required to be sucked away through an air duct installed on a processing shaft and finally enters a dust collector, so that the cleanliness of a processing area is guaranteed for better processing.

In order to facilitate the correspondence of the suction inlet of the dust collection pipeline and the processing shaft, the dust collection pipeline is generally connected by adopting a corrugated pipe, and in order to avoid the reverse blowing of the dust collector fault, a check valve needs to be additionally arranged in the dust collection pipeline so as to ensure that the check valve can be automatically closed when the reverse blowing occurs.

However, the currently adopted check valve is usually a plastic product, and because the check valve is fragile, the check valve cannot be fastened by applying a large acting force when being matched with the corrugated pipe, so that the check valve cannot be tightly matched, and the phenomenon of air leakage occurs.

Referring to fig. 1 and 2, the present embodiment provides a dust collection pipeline 100, which includes a first flange joint 110, a second flange joint 120 and a check valve 130, wherein the first flange joint 110 and the second flange joint 120 are connected, and the check valve 130 is disposed in the first flange joint 110 and/or the second flange joint 120, and the first flange joint 110 and/or the second flange joint 120 can be externally connected with a bellows (not shown in the drawings).

Specifically, by connecting the first flange joint 110 and the second flange joint 120, the check valve 130 is conveniently disposed within the protection space of the first flange joint 110 and the second flange joint 120, and at the same time, is conveniently connected with a bellows or other components. The check valve 130 may be disposed in the first flange joint 110 according to actual needs, i.e., the check valve 130 is located in the orthographic projection range of the first flange joint 110. The check valve 130 may be disposed in the second flange joint 120 according to actual needs, i.e. the check valve 130 is located in the orthographic projection range of the second flange joint 120. It is understood that the check valve 130 may be disposed in the first flange joint 110 and the second flange joint 120 according to practical needs, i.e. the check valve 130 is located in the forward projection range of the first flange joint 110 and the second flange joint 120 (please refer to the projection view in fig. 2). By adopting the matching mode, the check valve 130 has higher fitting degree with the first flange joint 110 and/or the second flange joint 120, which is beneficial to improving the tightness of the joint.

After the check valve 130 is provided in the first flange joint 110 and/or the second flange joint 120, a bellows may be connected to the first flange joint 110 or the second flange joint 120 depending on the actual installation environment, and the present utility model is used when the bellows is connected to one end. When connected in the middle of the bellows, the bellows needs to be connected to the first flange joint 110 and the second flange joint 120, respectively. The connecting and fixing of the corrugated pipe can be performed by adopting a binding hoop. Since the location of the application is at the first flange joint 110 and/or the second flange joint 120, there is no concern about damage to the non-return valve 130.

According to the dust collection pipeline 100 provided by the embodiment of the utility model, the first flange joint 110 is connected with the second flange joint 120, and the check valve 130 is arranged in the first flange joint 110 and/or the second flange joint 120, so that the check valve 130 can be protected, compared with a corrugated pipe, the inner walls of the first flange joint 110 and the second flange joint 120 are smoother, the degree of fit with the check valve 130 is higher, and the tightness of the matched and connected position of the check valve 130 is guaranteed. Meanwhile, when the check valve 130 is connected with the corrugated pipe, the corrugated pipe is connected with the first flange joint 110 and/or the second flange joint 120, no additional acting force is applied to the check valve 130, the check valve 130 is prevented from being damaged by stress, and reliability and stability in use are guaranteed.

As shown in fig. 3, the check valve 130 includes a housing 132, and a valve body 134 coupled to an inner wall of the housing 132, the valve body 134 being capable of preventing a medium of the second flange joint 120 from flowing backward to the first flange joint 110.

Specifically, the check valve 130 is cooperatively connected with the first flange joint 110 and/or the second flange joint 120 through the housing 132, and the valve body 134 disposed in the housing 132 plays a role in unidirectional flow. When the dust collection pipe 100 is connected from the first flange connector 110 to the second flange connector 120 in a unidirectional manner, the second flange connector 120 is used for connecting a dust collection end, and the first flange connector 110 is used for connecting an equipment end.

As shown in fig. 3 and 4, the valve body 134 includes a first barrier 1342 coupled to an inner wall of the housing 132, and a second barrier 1344 rotatably coupled to the first barrier 1342; the first baffle 1342 is provided with a via hole 1342a, and the via hole 1342a is used for conducting the valve body 134, and a first state with a preset included angle and a second state with a mutually attached state are arranged between the first baffle 1342 and the second baffle 1344.

Specifically, in the normal working state, the second flange joint 120 has a negative pressure, and by providing the through hole 1342a on the first baffle 1342, the second baffle 1344 rotates relative to the first baffle 1342 under the action of the negative pressure on the check valve 130, so as to reach the first state with a preset included angle, at this time, the through hole 1342a is not affected by the second baffle 1344, and the valve body 134 is in the first state of conduction. In the working state of the dust collector in which the air is blown reversely or in standby, the first barrier 1342 is attached to the second barrier 1344, and at this time, the through hole 1342a is blocked by the second barrier 1344, and the valve body 134 is in the second state of being closed. By adopting the form, the stability in use is guaranteed.

In addition, in practical applications, the preset included angle may be different according to the current power of the dust collector. For example, the second barrier 1344 may not be fully opened when the current power of the dust collector is small, and the preset angle may be 30 ° to 45 °, and the second barrier 134 may be opened by a larger angle when the current power of the dust collector is large, and the preset angle may be 70 ° to 90 °. Since both sides of the rotational connection on the first barrier 1342 are provided with the through holes 1342a. The second baffle 124 has an optimal circulation state when the plane is parallel to the length extension direction of the housing 132.

As shown in fig. 1, the second flange joint 120 is provided with a pressure gauge 140, the pressure gauge 140 is electrically connected with the processing equipment, and the pressure gauge 140 is used for detecting the pressure in the dust collection pipeline 100 and transmitting detection data to the processing equipment.

Specifically, by providing the pressure gauge 140 on the second flange joint 120, the magnitude of the air pressure at the second flange joint 120 can be detected. The processing device is connected with the pressure gauge 140, and can acquire the pressure value detected by the pressure gauge 140, so as to determine the current working state according to the acquired pressure value. For example, when the dust collector fails and dust cannot be collected, the space in the dust collection pipeline 100 is communicated with the atmosphere, the air pressure detected by the pressure gauge 140 is 0, and the collection value of processing equipment does not meet the working condition (if the collection value is set to be less than or equal to-1 kPa to be a normal value), the equipment does not process, so that pollution and damage of a processing shaft caused by that dust cannot be cleaned in time in the processing are avoided. When the dust collector fails to blow reversely, the check valve 130 acts to automatically close the second baffle 1344 to stop the passage; and the pressure gauge 140 detects that the pressure value is positive pressure, and the processing equipment system collects the numerical value and sounds a buzzer to give an alarm if the numerical value is positive pressure, so that a worker is reminded to stop the dust collector as soon as possible, and dust in the dust collector is prevented from being blown back into the processing equipment through the dust collection pipeline to cause pollution and damage to the processing shaft.

With continued reference to FIG. 1, the pressure gauge 140 includes a display 142, and a pressure sensor 144 coupled to the display 142, the pressure sensor 144 extending partially into the second flange joint 120; the second flange joint 120 is further connected to a mounting plate 170, and the display 142 is connected to the mounting plate 170.

Specifically, the mounting plate 170 is connected to the second flange connector 120, so that the display 142 can be conveniently mounted, and the current pressure condition can be displayed in the use process, so that the use state is more visual. The pressure sensor 144 senses the pressure in the second flange joint 120, so as to obtain the pressure in the dust collection pipeline 100.

As shown in fig. 2 and 4, the first flange joint 110 includes a first joint 112, a first receiving cavity 114 connected to the first joint 112, and a first connection plate 116 disposed at an end of the first receiving cavity 114 facing away from the first joint 112; the second flange joint 120 includes a second joint 122, a second receiving cavity 124 connected with the second joint 122, and a second connection plate 126 disposed at an end of the second receiving cavity 124 facing away from the second joint 122; the first connection plate 116 and the second connection plate 126 are connected.

Specifically, the first receiving chamber 114 and the second receiving chamber 124 are mainly used for receiving the check valve 130, and the first connector 112 and the second connector 122 are used for connecting with other components, such as bellows. After the check valve 130 is aligned, the first connecting plate 116 and the second connecting plate 126 are aligned and connected by a fastener. It should be noted that, in the embodiment of the present utility model, the shapes of the first connection board 116 and the second connection board 126 are not particularly limited, and may be circular, rectangular, or flexibly configured according to actual needs. By adopting the above form, the installation and alignment are simple and convenient, the check valve 130 can be better protected, and the tightness of the joint is improved.

Specifically, the first connector 112 and the first accommodating chamber 114 are connected in a smooth transition manner, so as to ensure the stability of the air flow. In practical applications, the diameter of the first connector 112 may be made equal to the diameter of the first receiving cavity 114. The diameter of the first joint 112 may be smaller than that of the first accommodating chamber 114, and may be flexibly set as required. Likewise, the second connector 122 and the second receiving chamber 124 are connected in a smooth transition manner to ensure the stability of the air flow. In practical applications, the diameter of the second joint 122 may be made equal to the diameter of the second receiving cavity 124. The diameter of the second connector 122 may be smaller than that of the second accommodating cavity 124, and may be flexibly set as required.

As shown in fig. 3, the outer ring of the housing 132 is provided with a limiting plate 136, and the limiting plate 136 is clamped between the first connecting plate 116 and the second connecting plate 126.

Specifically, by providing the limiting plate 136 on the outer ring of the housing 132, the check valve 130 can be limited, and axial movement of the check valve 130 during use can be prevented.
