Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, specifically a rapid vacuuming device. Background Technology

[0002] Vacuuming is one of the steps in the operation of a cleaning machine.

[0003] Traditional vacuuming devices often use a vacuum pump directly connected to the working chamber where the workpiece is placed to perform vacuum processes. For example, a vacuum cleaning machine for heat treatment of metal materials disclosed in CN220559909U and a fully enclosed vacuum cleaning mechanism and multi-stage fully enclosed vacuum cleaning device disclosed in CN211757170U both use a vacuum pump directly connected to the working chamber.

[0004] The traditional vacuuming process involves the workpiece entering the working chamber, turning on the vacuum pump to create a vacuum (which usually takes 2 minutes), completing the vacuuming process, restoring the standard atmospheric pressure, and then the workpiece leaving the working chamber.

[0005] There is an urgent need for a vacuuming device that can shorten the vacuuming time. Utility Model Content

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Please see Figures 1 to 6As shown in Specific Embodiment 1, a rapid vacuuming device includes a vacuum pump 1, a frame 7, and a pre-vacuum tank 2. The pre-vacuum tank 2 is installed on top of the frame 7, and the pre-vacuum tank 2 and vacuum pump 1 are arranged vertically. The vacuum pump 1 is connected to the pre-vacuum tank 2 via a pipeline, on which a first control valve 3 is installed. The pre-vacuum tank 2 is connected to an exhaust pipeline, on which a venting valve 4 and a silencer 5 are sequentially connected along the exhaust direction. The pre-vacuum tank 2 is connected to a working chamber 8 via a vacuuming pipeline, on which a second control valve 6 is installed. This invention, by adding a pre-vacuum pump 1, facilitates rapid vacuuming of the working chamber 8. The vacuuming time is only 20 seconds.

[0041] There are two vacuum pumps 1, which are arranged one above the other; the pipeline includes a main pipeline and two branch pipelines. One end of the main pipeline is connected to the pre-vacuum tank 2, and the other end of the main pipeline is connected to the two branch pipelines, which are respectively connected to the two vacuum pumps 1; a first control valve 3 is installed on the main pipeline.

[0042] The frame 7 includes an upper rectangular frame and a lower rectangular frame set at the top and bottom. The four corners of the upper rectangular frame are connected to the lower rectangular frame by columns. An inverted U-shaped seat is fixed on the upper rectangular frame. An installation seat is set on the outer edge of the pre-vacuum tank 2. The installation seat is erected on the inverted U-shaped seat, and the installation seat and the inverted U-shaped seat are detachably connected by bolts.

[0043] The frame 7 also includes an upper support frame 71 and a lower support frame 72 arranged vertically; the lower support frame 72 is detachably installed on the lower rectangular frame; the upper support frame 71 includes a horizontal support part, a crossbar is fixed to the front side of the horizontal support part, and the left and right ends of the crossbar are detachably connected to two columns located on the front side respectively; an inverted U-shaped support frame is connected to the rear of the horizontal support part, and the bottom of the inverted U-shaped support frame is detachably connected to the lower rectangular frame; the upper support frame 71 and the lower support frame 72 are respectively used to place two vacuum pumps 1.

[0044] Both the upper support frame 71 and the lower support frame 72 are located at the front end of the frame 7. The corners of the horizontal support section have notches to allow branch pipes to pass.

[0045] The top of the pre-vacuum tank 2 is equipped with a lifting ring.

[0046] The bottom of the pre-vacuum tank 2 is a cone shape with its axis tilted backward. This is to facilitate avoiding the vacuum pump 1.

[0047] The working chamber 8 includes a pressure cover 81 and a base 82 arranged at the top and bottom. The top of the pressure cover 81 is connected to a lifting drive mechanism for driving the pressure cover 81 to rise and fall. The pressure cover 81 is connected to the pre-vacuum tank 2 through a vacuum pipeline.

[0048] When in standby mode:

[0049] See Figure 1 Vacuum pump 1 remains on, first control valve 3 is open, and second control valve 6 is closed. At this time, pre-vacuum tank 2 is always in a high negative pressure state.

[0050] When a workpiece needs to be vacuumed:

[0051] The workpiece first enters and is placed on the base 82, then the cover 81 is closed, see below. Figure 2 At this time, the working chamber 8 forms a sealed space, and then the second control valve 6 opens. Since the pre-vacuum tank 2 is always in a high negative pressure state, it will instantly suck away the gas in the working chamber 8 and make the inside of the working chamber 8 quickly reach a high negative pressure state.

[0052] When the workpiece finishes vacuuming:

[0053] The second control valve 6 is closed, the vent valve 4 is opened, and atmospheric air enters the working chamber 8 from the silencer 5, restoring the working chamber 8 to standard atmospheric pressure. Subsequently, the pressure cap 81 is opened (see...). Figure 1 ), and remove the workpiece.
