Abstract
Description
Technical Field
[0001] This utility model relates to the field of liquid drainage technology for concentrated gas chambers, specifically an automatic liquid drainage device for concentrated gas chambers. Background Technology
[0002] Waste gas collection systems are highly efficient environmental protection devices primarily used for collecting and treating waste gases emitted from industrial and residential environments. These systems employ a series of technologies, such as adsorption, condensation, and biological treatment, to remove or transform harmful substances in the waste gases, thereby purifying them. Waste gas collection systems not only reduce environmental pollution from waste gases but also lower the concentration of harmful substances in the gases, thus protecting the health of employees and the environment.
[0003] In a volatile organic compound (VOC) collection system, the concentrator can concentrate large volumes of low-concentration waste gas into high-concentration, low-volume waste gas, thus reducing the investment and operating costs of treatment equipment and improving waste gas treatment efficiency. In the cooling zone of the concentrator, high-temperature gas exchanges heat with low-temperature inlet gas, which may lead to condensate formation. Therefore, a drain pipe is installed at the bottom of the concentrator to discharge the liquid. However, some harmful gases are discharged along with the waste liquid. To address this, an automatic drain device for the concentrator is proposed. Utility Model Content
[0004] The purpose of this invention is to provide an automatic liquid discharge device for a concentrated gas chamber, so as to solve the problem that harmful gases are discharged along with waste liquid in the prior art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic liquid draining device for a concentrated gas chamber, comprising a frame, a concentrated gas chamber within the frame, a draining mechanism at the bottom of the concentrated gas chamber, a liquid collecting cylinder fixedly installed at the bottom of the concentrated gas chamber, a liquid level sensor fixedly installed at the upper edge of the liquid collecting cylinder, an electric push rod fixedly installed at the bottom of the liquid collecting cylinder, a piston plate fixedly installed at the output end of the electric push rod, and a liquid inlet mechanism provided on the piston plate.
[0006] Preferably, the liquid collecting cylinder has an installation port at the middle position at the bottom and a drain port at the bottom edge. A sealing ring is provided in the installation port, and a drain pipe is fixedly installed in the drain port. A solenoid valve is provided on the drain pipe.
[0007] Preferably, the bottom of the concentrated gas chamber is provided with a connection interface, the liquid collecting cylinder is installed at the bottom of the concentrated gas chamber through the connection interface, the bottom of the piston plate is provided with a connecting groove, and the piston plate is installed at the output end of the electric push rod through the connecting groove.
[0008] Preferably, the electric push rod extends into the liquid collecting cylinder through the mounting port, the piston plate is movably mounted in the liquid collecting cylinder through the electric push rod, the stroke of the piston plate is half the height of the liquid collecting cylinder, and the drain pipe is installed on the liquid collecting cylinder through the drain port.
[0009] Preferably, the liquid inlet mechanism includes a liquid inlet on the piston plate, a sealing plunger is movably installed in the liquid inlet, a retainer is fixedly installed at the bottom of the liquid inlet, a return spring is fixedly installed in the retainer, a push rod is provided above the liquid inlet, and a mounting bracket is fixedly installed on the push rod.
[0010] Preferably, the mounting bracket has a mating groove at its bottom, and the top rod is installed at the bottom of the mounting bracket through the mating groove.
[0011] Preferably, the push rod is fixed to the liquid collecting cylinder by a mounting bracket, and the push rod is vertically aligned with the liquid inlet on the piston plate. One end of the return spring is fixed to the sealing plunger, and the other end of the return spring is fixed to the retainer.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. In this application, after the liquid level sensor detects that the liquid collection cylinder has reached the predetermined liquid capacity, it will trigger the electric push rod to drive the piston plate to move upward. During the process of the piston plate rising, a negative pressure is formed at the bottom of the liquid collection cylinder, which causes the upper liquid to be sucked into the lower part. When the electric push rod retracts, the piston plate moves downward, thereby realizing the discharge of the liquid in the lower part of the liquid collection cylinder.
[0014] 2. In this application, when the piston plate moves upward to its highest point, the push rod will press down the sealing plunger, causing the sealing plunger to disengage from the liquid inlet. After the sealing plunger disengages from the liquid inlet, the liquid in the upper part of the liquid collecting cylinder will enter the lower part of the liquid collecting cylinder through the liquid inlet. During the entire liquid inlet process, the gas in the concentrated gas chamber cannot pass through the liquid inlet. At the same time, when the electric push rod is retracted, the return spring will drive the sealing plunger to return to its original position, thereby blocking the liquid inlet and preventing the gas in the concentrated gas chamber from passing through the liquid inlet.

[0021] 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.
[0022] like Figure 1 Figure 2 and Figure 3 As shown, this utility model provides a technical solution for an automatic liquid draining device for a concentrated gas chamber, including a device frame 1, a concentrated gas chamber 2 inside the device frame 1, a liquid draining mechanism 5 at the bottom of the concentrated gas chamber 2, a liquid draining pipe 3 fixedly installed inside the liquid draining port 506, a solenoid valve 4 on the liquid draining pipe 3, and a liquid inlet mechanism 6 on the piston plate 503. By using the liquid draining mechanism 5 and the liquid inlet mechanism 6 together, the liquid in the concentrated gas chamber 2 can be drained, and the liquid draining can prevent gas leakage in the concentrated gas chamber 2.
[0023] like Figure 2 Figure 3 and Figure 4 As shown, the draining mechanism 5 includes a liquid collecting cylinder 501 fixedly installed at the bottom of the concentrated gas chamber 2. A liquid level sensor 502 is fixedly installed at the upper edge of the liquid collecting cylinder 501. An electric push rod 507 is fixedly installed at the bottom of the liquid collecting cylinder 501. A piston plate 503 is fixedly installed at the output end of the electric push rod 507. An installation port 505 is opened at the middle position at the bottom of the liquid collecting cylinder 501. A drain port 506 is opened at the bottom edge of the liquid collecting cylinder 501. A sealing ring 504 is provided in the installation port 505. A drain pipe 3 is fixedly installed in the drain port 506. A solenoid valve 4 is provided on the drain pipe 3. A connection interface is opened at the bottom of the concentrated gas chamber 2. The liquid collecting cylinder 501 is installed at the bottom of the concentrated gas chamber 2 through the connection interface. A connecting groove is opened at the bottom of the piston plate 503. The piston plate 503 is installed at the output end of the electric push rod 507 through the connecting groove.
[0024] Specifically, after the liquid level sensor 502 detects that the liquid collecting cylinder 501 is full, it drives the piston plate 503 to move upward via the electric push rod 507. As the piston plate 503 moves upward, a vacuum area is formed at the bottom of the liquid collecting cylinder 501. This vacuum area causes liquid in the upper part of the liquid collecting cylinder 501 to be drawn into its lower part. Furthermore, when the electric push rod 507 retracts, it causes the piston plate 503 inside the liquid collecting cylinder 501 to move downward. This discharges the liquid that originally entered the lower part of the liquid collecting cylinder 501. The entire process, achieved through the extension and retraction of the electric push rod 507, ensures that the liquid collecting cylinder 501 can effectively collect and discharge liquid.
[0025] like Figure 2 Figure 3 and Figure 5 As shown, the liquid inlet mechanism 6 includes a liquid inlet 603 opened on the piston plate 503, a sealing plunger 604 is movably installed in the liquid inlet 603, a retainer 606 is fixedly installed at the bottom of the liquid inlet 603, a return spring 605 is fixedly installed in the retainer 606, a push rod 602 is provided above the liquid inlet 603, a mounting bracket 601 is fixedly installed on the push rod 602, a docking groove is opened at the bottom of the mounting bracket 601, and the push rod 602 is installed at the bottom of the mounting bracket 601 through the docking groove.
[0026] Specifically, when the piston plate 503 moves upward to the highest point of its stroke, the push rod 602 applies pressure, pushing the sealing plunger 604 downward. This action causes the sealing plunger 604 to move away from the liquid inlet 603, thus breaking the seal. Once the sealing plunger 604 is disengaged from the liquid inlet 603, the liquid stored in the upper part of the collecting cylinder 501 flows smoothly into the lower part of the collecting cylinder 501 through the channel of the liquid inlet 603. During this liquid inlet process, the gas in the concentrating chamber 2 is effectively isolated and cannot enter the lower part of the collecting cylinder 501 through the liquid inlet 603. Furthermore, when the electric push rod 507 is retracted, the return spring 605 activates, pushing the sealing plunger 604 back into its original position. This reset action ensures that the sealing plunger 604 re-seales the liquid inlet 603, thereby preventing the gas in the concentrating chamber 2 from leaking out through the liquid inlet 603. In this way, the system ensures smooth liquid flow and effective gas isolation, guaranteeing the normal operation and sealing performance of the entire device.
[0027] Working principle: During use, the liquid collection cylinder 501 at the bottom of the concentrated gas chamber 2 collects the liquid in the gas chamber. When the liquid collection cylinder 501 is full of liquid, the liquid level sensor 502 can detect it. After the liquid level sensor 502 detects that the liquid collection cylinder 501 is full of liquid, it can drive the piston plate 503 to move upward through the electric push rod 507. When the piston plate 503 moves upward, a vacuum will be formed at the bottom of the liquid collection cylinder 501. When the piston plate 503 moves upward to the highest point, the push rod 602 will press down the sealing plunger 604, causing the sealing plunger 604 to disengage from the liquid inlet 603. After the sealing plunger 604 disengages from the liquid inlet 603, the liquid collection cylinder 501... The liquid in the upper part of the liquid collection cylinder 501 will enter the lower part of the liquid collection cylinder 501 through the liquid inlet 603. During the entire liquid inlet process, the gas in the concentration chamber 2 cannot pass through the liquid inlet 603. After the liquid enters the lower part of the liquid collection cylinder 501, the electric push rod 507 can be retracted and the solenoid valve 4 can be opened. When the electric push rod 507 is retracted, the return spring 605 will drive the sealing plunger 604 to reset, thereby blocking the liquid inlet 603 and preventing the gas in the concentration chamber 2 from being discharged. When the electric push rod 507 is retracted, it will drive the piston plate 503 in the liquid collection cylinder 501 to move downward, thereby discharging the liquid that has entered the lower part of the liquid collection cylinder 501.
