Description

Technical Field

[0001] The utility model belongs to the technical field of suction cups, and particularly relates to an electric large-flow negative pressure workstation. Background Art

[0002] In application scenarios such as industrial dust treatment and material suction, conventional negative pressure suction devices often do not have strong enough suction force, and the suction efficiency of large-particle dust or high-concentration materials is low. For example, in the dust collection link during cement production, if the negative pressure is insufficient, a large amount of dust will escape, wasting materials and polluting the environment.

[0003] The existing Chinese patent publication number CN220299715U discloses an electric suction cup, including a housing, a suction cup main body and a vacuum pump. The vacuum pump is arranged in the inner cavity of the housing. A connection end is arranged in the middle of the bottom surface of the housing. The suction cup main body is fixedly connected to the bottom of the housing through a connection port. A pipeline is opened from the side wall of the housing into the bottom wall. A plug for sealing the pipeline is fixedly connected to the side wall of the housing. The connection end and the vacuum pump are both connected to the pipeline. An electromagnetic valve electrically connected to the vacuum pump is also arranged in the inner cavity of the housing. After the electromagnetic valve and the vacuum pump are assembled into the housing, the occupied space volume is small, so the required installation space is reduced, which is more suitable for installation on different machines, facilitating installation and maintenance, conducive to expanding the scope of use, and the electromagnetic valve and the vacuum pump generate vacuum quickly, resulting in high grasping and releasing efficiency and convenient use.

[0004] However, during the use of the above patent, first, there is no built-in air purification and filtration device. As a result, when sucking dust or debris on the surface of an object, the dust and debris will be sucked into the micro diaphragm pump together with the air, which will cause the vacuum degree and flow rate of the electric suction cup to decrease or even have no vacuum degree. Second, some of the sucked objects are too light or the objects are electrostatic, and the object cannot be released after the electromagnetic valve breaks the vacuum.

[0005] Therefore, it is necessary to develop an electric large-flow negative pressure workstation for use. Summary of the Utility Model

[0006] The embodiment of the utility model provides an electric large-flow negative pressure workstation to solve the problems in the prior art.

[0007] The embodiment of the utility model adopts the following technical scheme: an electric large-flow negative pressure workstation, including a housing, end covers are respectively arranged at both ends of the housing. Two electromagnetic valves are arranged in the housing. A diaphragm pump is arranged in the housing. The diaphragm pump is communicated with the two electromagnetic valves. A quick connector is arranged at the top of the housing. The two electromagnetic valves are connected to the quick connector. A negative pressure filter is also arranged at the top of the housing. The negative pressure filter is communicated with the electromagnetic valve.

[0008] For a further technical solution, a mounting seat is provided at the bottom of the negative pressure filter, the negative pressure filter is snap-connected to the mounting seat, and the mounting seat is mounted on the top of the housing by screws.

[0009] For a further technical solution, the two solenoid valves are an intake solenoid valve and an exhaust solenoid valve respectively.

[0010] For a further technical solution, the negative pressure filter is connected to the intake solenoid valve, and a pipeline is provided between the negative pressure filter and the intake solenoid valve.

[0011] For a further technical solution, an aviation plug is provided on the housing, and the aviation plug is electrically connected to the diaphragm pump and the two solenoid valves.

[0012] For a further technical solution, the end cover is detachably connected to the housing.

[0013] The above at least one technical solution adopted in the embodiments of the present utility model can achieve the following beneficial effects:

[0014] First, the present utility model is equipped with a visual negative pressure filter, which solves the problem that traditional electric suction cups are prone to dust ingress, and the negative pressure filter can be replaced at any time. The negative pressure filter can filter impurities, dust and other pollutants in the intake air, and can filter out most of the dust and debris, preventing dust and debris from being sucked into the micro diaphragm pump together with the air when sucking the dust or debris on the surface of the object, which may cause the vacuum degree and flow rate of the electric suction cup to decrease or even have no vacuum degree.

[0015] Second, the present utility model is provided with large-flow solenoid valves to control intake and exhaust respectively, achieving one-key switching between positive pressure and negative pressure while ensuring large flow. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with specific embodiments of the present utility model and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] The following will detail the technical solutions provided by each embodiment of the present utility model with reference to the drawings.

[0023] Refer to Figures 1 to 2 As shown, an embodiment of the present utility model provides an electric high-flow negative pressure workstation, which includes a housing 1. End caps 2 are respectively provided at both ends of the housing 1. Two solenoid valves 3 are provided inside the housing 1. A diaphragm pump 4 is provided inside the housing 1. The diaphragm pump 4 is communicated with the two solenoid valves 3. A quick connector 5 is provided at the top of the housing 1. The two solenoid valves 3 are connected to the quick connector 5. A negative pressure filter 6 is further provided at the top of the housing 1. The negative pressure filter 6 is communicated with the solenoid valve 3. The negative pressure filter 6 is a visual negative pressure filter.

[0024] It should be noted that the quick connector 5 is connected to an existing negative pressure plate to adsorb materials.

[0025] The negative pressure filter 6 can filter impurities, dust and other pollutants in the incoming air, and can filter out most of the dust and debris, preventing dust and debris from being sucked into the diaphragm pump 4 together with the air when there is dust or debris on the surface of the object to be sucked, which may cause the vacuum degree and flow rate of the electric suction cup to decrease or even have no vacuum degree.

[0026] Working principle:

[0027] Intake process:

[0028] The intake solenoid valve is opened and the outlet solenoid valve is closed:

[0029] When the intake solenoid valve is energized and opened, the passage of external gas is opened. At this time, the outlet solenoid valve is in the closed state, and the gas can only enter the quick connector 5 from the intake solenoid valve.

[0030] The diaphragm inside the diaphragm pump 4 moves driven by a motor or other driving device. When the diaphragm moves backward, the volume of the pump chamber increases, forming a negative pressure.

[0031] Due to the opening of the intake solenoid valve, external gas enters the pump chamber of the diaphragm pump 4 under the action of negative pressure.

[0032] The intake solenoid valve is closed and the outlet solenoid valve is closed:

[0033] When the quick connector 5 does not need to intake air, the intake solenoid valve is de-energized and closed, and at this time, external gas cannot enter the quick connector 5.

[0034] The outlet solenoid valve remains closed, and the gas in the diaphragm pump 4 is temporarily sealed in the pump chamber. This can maintain the pressure stability in the quick connector 5 in some specific working scenarios, or prevent gas leakage and entry of external impurities during the equipment suspension.

[0035] Outlet process:

[0036] The intake solenoid valve is closed and the outlet solenoid valve is open:

[0037] When it is necessary to discharge the gas in the diaphragm pump 4, the intake solenoid valve remains closed and the outlet solenoid valve is energized and opened.

[0038] The diaphragm of the diaphragm pump 4 moves forward, the volume of the pump chamber decreases, the gas is compressed, and the pressure increases.

[0039] Since the outlet solenoid valve is open, the compressed gas is discharged from the pump chamber through the outlet solenoid valve to the quick connector 5.

[0040] It should be noted that the maximum flow rate of the electric large-flow negative pressure workstation can reach 27 L / min.

[0041] Specifically, an installation seat 8 is provided at the bottom of the negative pressure filter 6, the negative pressure filter 6 is snap-connected to the installation seat 8, and the installation seat 8 is installed on the top of the housing 1 by screws;

[0042] The negative pressure filter 6 is snap-connected to the installation seat 8, which can quickly replace the negative pressure filter 6.

[0043] Specifically, the two solenoid valves 3 are respectively an intake solenoid valve and an outlet solenoid valve;

[0044] The negative pressure filter 6 is connected to the intake solenoid valve, and a pipeline is provided between the negative pressure filter 6 and the intake solenoid valve.

[0045] Intake solenoid valve: In the intake part, when the intake solenoid valve is not energized, it allows gas to enter the diaphragm pump 4 through the housing 1; when the intake solenoid valve is energized, it closes the intake channel to prevent gas from entering. This can accurately control the gas intake according to the working requirements of the quick connector 5.

[0046] Outlet solenoid valve: In the outlet section, when the outlet solenoid valve is de-energized, the gas discharged by the diaphragm pump 4 will not pass through the inside of the housing 1; when the outlet solenoid valve is energized, the gas is blown out through the inside of the housing 1. By controlling the on / off of the outlet solenoid valve, the blowing path and function of the gas can be adjusted, such as for operations like making materials fall off.

[0047] Specifically, an aviation plug 7 is provided on the housing 1, and the aviation plug 7 is electrically connected to the diaphragm pump 4 and the two solenoid valves 3; the aviation plug 7 can be connected to an external controller, and the controller is used to control the opening and closing of the inlet solenoid valve and the outlet solenoid valve, and the functions of positive pressure and negative pressure can be switched with one key.

[0048] Specifically, the end cover 2 is detachably connected to the housing 1; when repairing and inspecting the pipelines, solenoid valves 3 and diaphragm pump 4 inside the housing 1, the end cover 2 can be detached from the housing 1.

[0049] The above are only the embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, various modifications and changes can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the scope of the claims of the present invention.
