Description

Technical Field

[0001] The present invention relates to the technical field of vacuum sewage continuous collection, temporary storage and periodic transportation system, which is a vacuum well system, having a temporary sewage collection tank that uses a vacuum sewage valve for periodic sewage discharge, and can transport sewage in its sewage collection tank to a downstream vacuum collection pipeline network, and is controlled by a control device using a pressure difference drive control method. In the entire vacuum well system, there is condensed water in its internal chamber. Therefore, regarding the collection and discharge of condensed water, the present invention particularly relates to a vacuum well equipment cavity water collection and drainage device. Background Art

[0002] It is a conventional technology to collect liquid or sewage by vacuum technology. It relies on a pipe based on the principle of vacuum or negative pressure air flow conveying force that inhales air at one end and discharges air at the other end to convey domestic sewage from a building to a distant sewage pool or vacuum collection and conveying pipeline system. In the intermediate process, a temporary sewage storage tank is required. The sewage tank has an inlet connected to the sewage outlet of the building, a sewage suction port connected to the vacuum sewage conveying pipeline, and a vacuum sewage valve connecting the sewage suction port and the vacuum sewage conveying pipeline. The vacuum sewage valve has a control system or device. Its basic operating process is that when the sewage water level in the storage tank reaches a first preset value, the controller applies vacuum force to the vacuum sewage valve to suck and drain the sewage, until the sewage water level in the sewage tank drops to another preset value, the control system closes the vacuum sewage valve. We define this technical solution as a vacuum sewage continuous collection, temporary storage and periodic conveying system, that is, a vacuum well.

[0003] Generally, in the field of liquid or sewage collection technology, it is a well-known technology to use vacuum technology to collect liquid or sewage. The inside of the vacuum well is generally divided into a sewage chamber and an equipment chamber, which are separated by a partition plate, so as to achieve dry and wet separation, avoid direct air communication between the upper and lower chambers, and further ensure the environmental requirements of the equipment in the equipment chamber; and the necessary installation components in the equipment chamber include the following:

[0004] (1) Vacuum drain valve: used to connect the drain pipe, one end of which extends into the sewage chamber and the other end is connected to the downstream pipe. Based on the principle of pressure difference, the pneumatic controller controls the deformation or reset of the internal corrugated diaphragm to realize the opening and closing of the drain pipe;

[0005] (2) Liquid level sensor: used to monitor the change of liquid level in real time. When the liquid level changes, the air pressure above the liquid level will also change, that is, the air pressure increases when the liquid level rises, and decreases when the liquid level decreases. The change of air pressure generates a pressure difference, which can be used to control the operation of the pneumatic controller.

[0006] (3) Pneumatic controller: It uses pressure difference for driving control. Through the liquid level signal transmitted by the liquid level sensor, vacuum or air is intermittently introduced into the connection port between the pneumatic controller and the vacuum drain valve. When vacuum is passed, the vacuum drain valve is in the open state, and when air is introduced, the vacuum drain valve is in the closed state.

[0007] However, for pneumatic controllers, the internal corrugated diaphragm assembly is very easy to be affected by damp dust and its sealing effect, thus affecting the function of the pneumatic controller. If the internal chamber of the pneumatic controller does not have an effective active water collection and drainage structure design, the air inside the chamber will produce condensed water when it is subjected to drastic changes in state such as impact and collision. These condensed water will affect both the efficiency of the controller and the function of the controller. There are two sources of condensed water. One is the condensed water condensed at the air inlet of the controller after the dry hot air from the ground enters the dark, damp and cold chamber of the vacuum well equipment; the other is the condensed water produced by the impact, collision and other drastic changes in the state of the air in the chamber inside the controller. condensed water; therefore, in the prior art, a filtering device is designed inside the pneumatic controller to filter the air entering the pneumatic controller, thereby gathering the condensed water and finally discharging it from the bottom of the pneumatic controller; at this time, since the pneumatic controller is installed in the equipment cavity, if the condensed water is directly discharged into the equipment cavity, it will affect the dryness of the equipment cavity, and then affect the normal operation of the equipment; at the same time, the equipment cavity itself will also produce condensed water due to changes in temperature and other conditions, so it is particularly important to realize the treatment of condensed water; the present invention has developed a vacuum well equipment cavity water collection and drainage device to solve the problems existing in the prior art. After searching, no technical solutions identical or similar to the present invention were found. Summary of the invention

[0008] The purpose of the present invention is to provide a vacuum well equipment cavity water collection and drainage device to solve the problem in the prior art of vacuum well technology for dry-wet separation that condensed water is easily generated in the equipment cavity and is difficult to discharge.

[0009] The technical solution of the present invention is: a vacuum well equipment cavity water collection and drainage device, including a water collection and drainage column, a water collection pipeline distributed inside the water collection and drainage column, and a drainage pipeline; a water collection cavity for collecting liquid is provided at the lower end of the water collection and drainage column; the water collection pipeline includes an external drainage inlet and a water collection outlet extending to one side of the water collection cavity; the drainage pipeline includes a water collection inlet extending into the water collection cavity and an external drainage outlet for discharging liquid in the water collection cavity by using a pressure difference.

[0010] Preferably, the lower end of the water collecting and draining column has a mounting seat in an integrated structure, the water collecting chamber is arranged on the lower end surface of the mounting seat, and extends toward the side wall of the mounting seat to achieve communication with the outside of the mounting seat; a long-rod screw is provided through the end surface of the lower end of the mounting seat deviating from the water collecting chamber, which is used to achieve the installation and fixation of the water collecting and draining column.

[0011] Preferably, the water collection pipeline includes a first horizontal pipeline and a first vertical pipeline that are connected to each other, the end of the first horizontal pipeline away from the first vertical pipeline forms an external drainage inlet, the lower end of the first vertical pipeline forms a water collection outlet, and the first vertical pipeline is set away from the central axis of the water collection drainage column.

[0012] Preferably, the number of the first horizontal pipelines is greater than one, and they are distributed sequentially along the central axis of the water collection and drainage column.

[0013] Preferably, the drainage pipeline includes a second horizontal pipeline and a second vertical pipeline that are connected to each other, the end of the second horizontal pipeline away from the second vertical pipeline forms an external drainage outlet, the lower end of the second vertical pipeline forms a water collection inlet, and the second vertical pipeline is arranged along the central axis of the water collection drainage column.

[0014] Preferably, a guide column is provided at the water collection inlet, which is an integral structure with the mounting seat, and the lower end surface of the guide column and the lower end surface of the mounting seat are in the same horizontal plane. The water collection inlet is evenly distributed on the side wall of the guide column, and the height is lower than the height of the upper end surface of the water collection chamber.

[0015] Compared with the prior art, the advantages of the present invention are:

[0016] (1) The present invention is applied to a vacuum well system. The equipment cavity and the sewage cavity are separated into dry and wet areas by a partition inside the vacuum well. However, due to the flow of gas, especially after the dry and hot air on the ground enters the dark, damp and cold vacuum well equipment cavity, it is easy to condense and form condensed water. If the condensed water is all collected in the equipment cavity and cannot be discharged after a long time, it is impossible to meet the working requirements of various devices in the equipment cavity for a dry environment, thereby greatly reducing the working efficiency and service life of the equipment.

The former is collected into the water collection cavity through the partition, and the latter is collected into the water collection cavity through the water collection pipeline. The drainage pipeline is used to discharge the condensed water in the water collection cavity through the pressure difference. At this time, the external drainage outlet is used to connect the pipeline extending into the sewage cavity. When the liquid level in the sewage cavity drops, the air pressure above the liquid level in the pipeline gradually drops, so that the condensed water in the water collection cavity is sucked in and discharged into the sewage cavity through the pressure difference.

DETAILED DESCRIPTION

[0027] The present invention is further described in detail below in conjunction with specific embodiments:

[0028] like Figure 1 As shown, a vacuum well equipment cavity water collection and drainage device is used to be installed in a vacuum well system. First, regarding the vacuum well 1, a partition 2 is arranged inside it, and the inside of the vacuum well 1 is divided into a sewage cavity 3 at the bottom and an equipment cavity 4 at the top. The sewage cavity 3 is used to temporarily store domestic sewage from a sewage source, and the equipment cavity 4 is used to install a control device for controlling the sewage in the sewage cavity 3 to be discharged into a downstream pipeline. The control device generally includes a vacuum sewage valve, a liquid level sensor, and a pneumatic controller. Because the vacuum well 1 is arranged below the ground, and the work of the control device involves the flow of gas, when the dry and hot air on the ground enters the dark, damp and cold vacuum well equipment cavity 4, it is easy to condense to form condensed water. If the condensed water is all collected in the equipment cavity 4 after a long time and cannot be discharged, the working requirements of various devices in the equipment cavity 4 for a dry environment cannot be met, thereby greatly reducing the working efficiency and service life of the equipment. Therefore, the present invention has developed a vacuum well equipment cavity 4 water collection and drainage device for realizing water collection and drainage in the equipment cavity 4, and effectively meeting the dryness of the equipment cavity 4.

[0029] like Figure 2 As shown, there is a concave cavity 5 on the upper end surface of the partition 2, so that the condensed water in the equipment cavity 4 can be collected in the concave cavity 5, and a water collecting and drainage device for the vacuum well equipment cavity 4 is fixed on the end surface of the concave cavity 5, and its structure includes a water collecting and drainage column 6, a water collecting pipeline 10 distributed inside the water collecting and drainage column 6, and a drainage pipeline 15; wherein, a water collecting cavity 8 for collecting liquid is provided at the lower end of the water collecting and drainage column 6; the water collecting pipeline 10 includes an external drainage inlet 13 and a water collecting outlet 14 extending to one side of the water collecting cavity 8; the drainage pipeline 15 includes a water collecting inlet 18 extending into the water collecting cavity 8 and an external drainage outlet 19 for discharging liquid in the water collecting cavity 8 by using a pressure difference.

[0030] The more specific structure is as follows:

[0031] like Figure 3 , Figure 4 , Figure 5As shown, the lower end of the water collecting and draining column 6 has a mounting seat 7 which is arranged in an integrated structure. The water collecting chamber 8 is arranged on the lower end surface of the mounting seat 7 and extends toward the side wall of the mounting seat 7 to achieve communication with the outside of the mounting seat 7. In this embodiment, the water collecting chamber 8 is designed as a Y-shaped structure; a long rod screw 9 is provided through the end surface of the lower end of the mounting seat 7 which deviates from the water collecting chamber 8, so as to realize the fixed installation of the water collecting and draining column 6 on the partition 2.

[0032] The water collection pipeline 10 includes a first horizontal pipeline 11 and a first vertical pipeline 12 which are connected to each other. The number of the first horizontal pipelines 11 is greater than one, and they are distributed in sequence along the central axis of the water collection drainage column 6. The end of the first horizontal pipeline 11 away from the first vertical pipeline 12 forms an external drainage inlet 13, and the lower end of the first vertical pipeline 12 forms a water collection outlet 14, and the first vertical pipeline 12 is set away from the central axis of the water collection drainage column 6.

[0033] The drainage pipeline 15 includes a second horizontal pipeline 16 and a second vertical pipeline 17 that are connected to each other. An external drainage outlet 19 is formed at one end of the second horizontal pipeline 16 away from the second vertical pipeline 17. A water collection inlet 18 is formed at the lower end of the second vertical pipeline 17, and the second vertical pipeline 17 is arranged along the central axis of the water collection drainage column 6; wherein, a guide column that is integrally arranged with the mounting seat 7 is arranged at the water collection inlet 18, and the lower end surface of the guide column and the lower end surface of the mounting seat 7 are in the same horizontal plane, and the water collection inlet 18 is evenly distributed on the side wall of the guide column, and the height is lower than the height of the upper end surface of the water collection chamber 8, so that the drainage pipeline 15 can discharge more condensed water in the water collection chamber 8.

[0034] In the present invention, the sources of condensed water are mainly:

[0035] (1) Inside the equipment cavity 4: When the dry and hot air from the ground enters the dark, damp and cold vacuum well equipment cavity 4, it is easy to condense to form condensed water, such as Figure 6 As shown, the condensed water in the equipment cavity 4 flows along the partition 2 into the concave cavity 5 and enters the water collecting cavity 8 again;

[0036] (2) Inside the pneumatic controller: Air will flow into the pneumatic controller. If it is not filtered, the internal corrugated diaphragm assembly will be easily affected by damp dust and the sealing effect will be affected, which will further affect the function of the pneumatic controller. Therefore, the air entering the pneumatic controller is filtered, and the condensed water will eventually be discharged from the lower end of the pneumatic controller. At this time, the condensed water is connected to the external drainage inlet 13, such as Figure 6 As shown, condensed water flows along the water collecting pipe 10 and enters the water collecting chamber 8; therefore, the number of external drainage inlets 13 is the same as the number of pneumatic controllers in the equipment chamber 4; however, in this embodiment, the external drainage inlet 13 is not limited to being connected to the pneumatic controller, but is used to connect a series of devices in the equipment chamber 4 that can generate condensed water, so as to discharge the condensed water.

[0037] When the condensed water enters the water collecting chamber 8, Figure 6 As shown, the condensed water will be discharged along the drainage pipe 15, and the power of discharge is mainly based on the pressure difference principle; when the present invention is installed, the external drainage outlet 19 is used to connect the pipe extending into the sewage chamber 3. When the liquid level in the sewage chamber 3 drops, the liquid level inside the pipe will also drop. At this time, the air pressure above the liquid level in the pipe will drop, thereby sucking the condensed water in the connected water collection chamber 8 into the pipe and discharging it into the sewage chamber 3; the present invention has a simple structure and is easy to manufacture, including the injection molding of the overall structure and the opening of the first horizontal pipe 11, the first vertical pipe 12, the second horizontal pipe 16 and the second vertical pipe 17, which are all very convenient; but installing the present invention in the equipment chamber 4 of the vacuum well can play a very important role and effectively ensure the relative dryness of the equipment chamber 4, thereby providing a good dry environment for the operation of the device in the equipment chamber 4.

[0038] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with this technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the scope of protection of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is limited by the attached claims rather than the above description, so it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the present invention, and any figure mark in the claims should not be regarded as limiting the claims involved.
