Description

Technical Field

[0001] This utility model relates to the field of vacuum system equipment, and in particular to an automatic condensate recovery device. Background Technology

[0002] In vacuum systems, traditional condensers require manual discharge of condensate after shutting down the equipment and breaking the vacuum. This method not only affects continuous operation and reduces production efficiency but can also damage the equipment and increase maintenance costs due to frequent start-ups and shutdowns. Therefore, there is an urgent need for a device that can automatically recover condensate without shutting down the system. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide an automatic condensate recovery device to solve the problem that manual operation is required when the condenser discharges condensate in the prior art.

[0004] To address the problems in the existing technology, the technical solution of this utility model is as follows:

[0005] An automatic condensate recovery device includes a condenser located between a Roots pump and a vacuum pump in a vacuum system. The condenser is divided into an upper chamber and a lower chamber from top to bottom, which are separated by a baffle. A through hole is opened in the vertical direction of the baffle, and a stop block passes through the through hole. The stop block includes a stop block cap and a stop block handle, with the stop block handle placed in the through hole and the stop block cap located above the through hole. An electromagnetic plate is provided inside the baffle.

[0006] The electromagnetic plate is connected to a controller outside the condenser via wires, which pass through the contact surface between the baffle and the condenser.

[0007] The cross-section of the stop block handle is smaller than the cross-section of the through hole, and there is a gap between the stop block handle and the through hole; the cross-section of the stop block cap is larger than the cross-section of the through hole, and the stop block cap completely covers the through hole.

[0008] A sealing gasket is provided at the contact point between the stop cap and the baffle.

[0009] The stop cap is a magnetic stop cap.

[0010] The upper cavity is equipped with a level gauge one on its side wall, and the lower cavity is equipped with a level gauge two on its side wall.

[0011] The lower cavity is connected to a vent valve on the outside and an automatic drain valve at the bottom, with the automatic drain valve connected to a degassing tank.

[0012] A manual drain valve is connected to the bottom of the lower chamber.

[0013] The condenser is connected to a conveying pipe on its outer side. The two ends of the conveying pipe are connected to the upper chamber and the lower chamber, respectively. A valve is installed on the conveying pipe.

[0014] The level gauge 1, level gauge 2, vent valve, stop block, solenoid plate, valve and automatic drain valve are interlocked and controlled.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model features interlocking and coordinated operation of the level gauge and valves, achieving automatic recovery without shutting down the machine, compared to the traditional method of manually draining condensate. When the level gauge 1 in the upper chamber of the condenser detects condensate, it automatically interlocks the relevant valves or stops to prevent condensate from flowing into the lower chamber; when the level gauge 2 in the lower chamber detects a change in liquid level, it automatically interlocks the relevant valves or stops to allow condensate to enter the lower chamber, ensuring continuous operation of the equipment and significantly improving production efficiency.

[0017] 2. This utility model adopts two sets of automatic drainage channels: through holes and conveying pipes; the drainage channel can be flexibly selected according to the actual amount of condensate generated. The two sets of automatic drainage channels do not interfere with each other and can be used individually or simultaneously.

[0018] 3. This utility model achieves automatic condensate recovery without shutting down the system, while retaining a manual drain valve. In case of automatic system failure or special operation, the condensate can be manually drained, enhancing operational flexibility. Attached Figure Description

[0023] The embodiments of this utility model will be described in detail below with reference to the examples. The following examples are only used to illustrate this utility model and should not be regarded as limiting the scope of this utility model.

[0024] Example 1

[0025] An automatic condensate recovery device includes a condenser 1, which is divided into an upper chamber 1-1 and a lower chamber 1-2 from top to bottom, and the upper chamber 1-1 and the lower chamber 1-2 are separated by a baffle 7; a through hole 11 is opened in the vertical direction of the baffle 7, and a stop block 6 passes through the through hole 11; the stop block 6 includes a stop block cap 6-1 and a stop block handle 6-2, the stop block handle 6-2 is placed in the through hole 11, and the stop block cap 6-1 is located above the through hole 11; an electromagnetic plate 8 is provided inside the baffle 7.

[0026] The electromagnetic plate 8 is connected to the controller 8-2 outside the condenser 1 via a wire 8-1, which passes through the contact surface between the baffle 7 and the condenser 1.

[0027] The cross-section of the stop block handle 6-2 is smaller than the cross-section of the through hole 11, and there is a gap between the stop block handle 6-2 and the through hole 11; the cross-section of the stop block cap 6-1 is larger than the cross-section of the through hole 11, and the stop block cap 6-1 completely covers the through hole 11.

[0028] A sealing gasket 6-3 is provided at the contact position between the stop cap 6-1 and the baffle 7.

[0029] The stop cap 6-1 is a magnetic stop cap.

[0030] The upper cavity 1-1 is provided with a level gauge 2 on its side wall, and the lower cavity 1-2 is provided with a level gauge 3 on its side wall.

[0031] The outer side of the lower cavity 1-2 is connected to the vent valve 5, and the bottom is connected to the automatic drain valve 10, which is connected to the degassing tank 12.

[0032] The bottom of the lower chamber 1-2 is connected to a manual drain valve 4.

[0033] The condenser 1 is connected to a conveying pipe 9 on its outer side. The two ends of the conveying pipe 9 are connected to the upper chamber 1-1 and the lower chamber 1-2, respectively. A valve 9-1 is provided on the conveying pipe 9.

[0034] The level gauge 1 (2), level gauge 2 (3), vent valve (5), stop block (6), solenoid plate (8), valve 9-1, and automatic drain valve (10) are interlocked for control.

[0035] Example 2

[0036] use Figure 1 The device shown operates as follows:

[0037] Operating independently via the through-hole passage: Initially, the manual drain valve 4, vent valve 5, valve 9-1, and automatic drain valve 10 are closed. Activating the solenoid plate 8 causes the magnetic poles of the contact surfaces of the solenoid plate 8 and the stop cap 6-1 to be the same, lifting the stop cap 6. Condensate flows from the upper chamber 1-1 into the lower chamber 1-2 through the gap between the through-hole 11 and the stop cap 6. Once the level gauge 2 detects condensate, the current direction of the solenoid plate 8 is adjusted so that the magnetic poles of the contact surfaces of the solenoid plate 8 and the stop cap 6-1 are opposite, ensuring close contact and isolating the upper chamber 1-1 from the lower chamber 1-2. The automatic drain valve 10 and... The opening of the vent valve 5 breaks the vacuum state of the lower chamber 1-2, creating a pressure difference between the lower chamber 1-2 and the degassing tank 12. The condensate enters the degassing tank 12 from the lower chamber 1-2. After the level gauge 2 detects that the liquid level in the lower chamber 1-2 has decreased, the vent valve 5 and the automatic drain valve 10 are closed. The current direction of the electromagnetic plate 8 is adjusted so that the magnetic poles of the contact surfaces of the electromagnetic plate 8 and the stop cap 6-1 are the same. The stop cap 6 is lifted up, and the condensate recovery continues for the next cycle.

[0038] The delivery pipeline operates independently: In the initial state, the manual drain valve 4, vent valve 5, and automatic drain valve 10 are closed, and the stop block 6 is lowered. Valve 9-1 is opened, and condensate flows from the upper chamber 1-1 into the lower chamber 1-2 through the delivery pipeline 9. After the level gauge 2 detects the condensate, valve 9-1 is closed, isolating the upper chamber 1-1 and the lower chamber 1-2. The automatic drain valve 10 and vent valve 5 are opened, breaking the vacuum in the lower chamber 1-2 and creating a pressure difference between the lower chamber 1-2 and the degassing tank 12. Condensate then enters the degassing tank 12 from the lower chamber 1-2. After the level gauge 3 detects a decrease in the liquid level in the lower chamber 1-2, vent valve 5 and automatic drain valve 10 are closed, and valve 9-1 is opened to continue the condensate recovery for the next cycle.

[0039] Simultaneous operation of the through-hole and delivery pipeline: When the condensate volume is large and needs to be quickly delivered to the lower chamber 1-2, and a single through-hole or delivery pipeline cannot meet the demand, both the through-hole and delivery pipeline can be activated simultaneously. Initially, the manual drain valve 4, vent valve 5, and automatic drain valve 10 are closed. The electromagnetic plate 8 is activated, making the magnetic poles of the contact surfaces of the electromagnetic plate 8 and the stop cap 6-1 the same, thus lifting the stop cap 6; simultaneously, valve 9-1 is opened, and the condensate flows into the lower chamber 1-2 through the through-hole 11 and delivery pipeline 9; after the level gauge 2 detects the condensate, the current direction of the electromagnetic plate 8 is adjusted so that the magnetic poles of the contact surfaces of the electromagnetic plate 8 and the stop cap 6-1 are opposite, ensuring close contact, and valve 9-1 is closed, isolating the upper chamber 1-1 and the lower chamber 1-2. The automatic drain valve 10 is then opened. The opening of vent valve 5 breaks the vacuum state of lower chamber 1-2, creating a pressure difference between lower chamber 1-2 and degassing tank 12. Condensate enters degassing tank 12 from lower chamber 1-2. After level gauge 23 detects a decrease in the liquid level in lower chamber 1-2, vent valve 5 and automatic drain valve 10 are closed, valve 9-1 is opened, and the current direction of electromagnetic plate 8 is adjusted so that the magnetic poles of the contact surfaces of electromagnetic plate 8 and stop cap 6-1 are the same. Stop cap 6 is lifted up, and condensate recovery continues in the next cycle.

[0040] The conveying pipeline passage and the through hole passage do not interfere with each other. The two passages can operate independently or work together. If one passage fails, the other passage can be used to ensure normal conveying. When the automatic drain valve 10 or the degassing tank 12 fails, the condensate can also be discharged from the lower chamber 1-2 through the manual drain valve 4.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
