Description

Technical Field

[0001] The utility model belongs to the technical field of chemical engineering and relates to a liquid storage device, in particular to a liquid storage device which is easy to replace a long-rod type liquid level gauge. Background Art

[0002] In chemical production, liquid storage devices are often required to store raw materials, intermediate products and waste. In order to accurately understand the amount of liquid in the liquid storage device, the liquid storage device usually needs to be used with a liquid level meter. There are many types of liquid level meters, including rod level gauges, magnetic flap level gauges, float level gauges, radar level gauges, immersion level gauges, ultrasonic level gauges, etc. Among them, the rod level gauge is a simple and commonly used liquid level detection device with many advantages: simple installation: no special tools or complex calibration are required, and it can be directly inserted into the container for use; convenient maintenance: due to its simple structure, low failure rate, easy daily inspection and maintenance; strong adaptability: suitable for containers of various shapes, and most non-corrosive liquids; cost-effectiveness: compared with electronic or radar level gauges, the price is more economical. However, since the rod level gauge needs to be inserted into the container for use, it is generally installed from the top of the container vertically from top to bottom, which is suitable for shorter containers, because if it is a taller liquid storage device, the height of the matching rod level gauge is also higher, so a factory building of at least twice the height is required. In addition, if the container is too high or large, it is not convenient to disassemble and replace the rod type liquid level gauge. Utility Model Content

[0003] The utility model provides a liquid storage device which is easy to replace a long-rod type liquid level gauge, so as to overcome the defects of the prior art.

[0004] To achieve the above-mentioned purpose, the utility model provides a liquid storage device which is easy to replace a long-rod liquid level gauge, and is equipped with a rod-type liquid level gauge, and has the following characteristics: it includes a liquid storage tank and a liquid level tube; the liquid level tube is vertically arranged on the outside of the liquid storage tank and is connected to the liquid storage tank, and has the same liquid level as the liquid storage tank; the liquid level tube is detachably connected to the liquid storage tank; the rod-type liquid level gauge is inserted into the liquid level tube to measure the liquid level therein.

[0005] Furthermore, the liquid level pipe is equipped with a plurality of connecting pipes; one end of the connecting pipe is fixed to the side wall of the liquid storage tank and connected to the interior thereof, and the other end is fixed to the side wall of the liquid level pipe and connected to the interior thereof; the plurality of connecting pipes are arranged in the vertical direction.

[0006] Furthermore, the connecting pipe is divided into two sections, one section is fixed to the liquid storage tank, and the other section is fixed to the liquid level pipe, and the two sections are fixedly connected by a fixing flange.

[0007] Furthermore, a maintenance valve is provided on the connecting pipe and is located between the fixed flange and the liquid storage tank.

[0008] Furthermore, the connecting pipe is arranged horizontally.

[0009] Furthermore, there are two connecting pipes, the upper part of the liquid level pipe is fixedly connected to the upper part of the liquid storage tank through one connecting pipe, and the lower part of the liquid level pipe is fixedly connected to the lower part of the liquid storage tank through another connecting pipe.

[0010] Furthermore, the top end of the liquid level tube is provided with a socket, and the rod-type liquid level gauge extends into the liquid level tube from the socket.

[0011] Furthermore, the socket has an internal thread that matches the external thread of the rod-type liquid level gauge, and the rod-type liquid level gauge is fixed to the socket thread.

[0012] Furthermore, the bottom end of the liquid level tube has a liquid discharge port.

[0013] Furthermore, a drain valve is provided on the drain port.

[0014] The beneficial effect of the utility model is that the utility model provides a liquid storage device that is easy to replace a long rod liquid level gauge. A liquid level tube connected to the liquid storage tank is arranged on the side of the liquid storage tank, and the same liquid level as that in the liquid storage tank can be obtained. In this way, the liquid level measured by the rod liquid level gauge inserted into the liquid level tube is equivalent to the liquid level in the liquid storage tank. The acquired data directly represents the actual liquid level of the liquid storage tank, which greatly improves the accuracy and reliability of the measurement, and provides solid data support for industrial production process control, material management and other links. At the same time, the liquid level tube is detachably connected to the liquid storage tank. When the rod liquid level gauge needs to be replaced, the liquid level tube with the rod liquid level gauge inserted can be removed as a whole, and the rod liquid level gauge can be replaced in a non-vertical state. That is, in the process of removing and inserting the rod liquid level gauge into the liquid level tube, the rod liquid level gauge does not need to be in a vertical state, which greatly relaxes the operating conditions for maintenance and replacement, significantly saves time cost, labor cost, etc., improves maintenance efficiency, and makes maintenance and replacement convenient, saving time and effort.

[0020] The specific implementation of the present utility model is described below with reference to the accompanying drawings.

[0021] like Figure 1 As shown, the utility model provides a liquid storage device that is easy to replace a long rod type liquid level gauge, and is equipped with a rod type liquid level gauge A. The device includes a liquid storage tank 1 and a liquid level pipe 2. The liquid level pipe 2 is vertically arranged outside the liquid storage tank 1 and is connected to the liquid storage tank 1, and has the same liquid level as the liquid storage tank 1. The liquid level pipe 2 is detachably connected to the liquid storage tank 1. The rod type liquid level gauge A is inserted into the liquid level pipe 2 to measure the liquid level therein.

[0022] Specifically, the liquid level pipe 2 is equipped with a plurality of connecting pipes 3. The connecting pipe 3 is arranged horizontally, one end of which is fixed to the side wall of the liquid storage tank 1 and communicated with the inside thereof, and the other end of which is fixed to the side wall of the liquid level pipe 2 and communicated with the inside thereof. The plurality of connecting pipes 3 are arranged in a vertical direction, that is, arranged in the arrangement direction of the liquid level pipe 2, so that the liquid level pipe 2 can be fixedly communicated with the liquid storage tank 1 through the plurality of connecting pipes 3.

[0023] The connecting pipe 3 is divided into two sections, one section is fixed to the liquid storage tank 1 , and the other section is fixed to the liquid level pipe 2 . The two sections are fixedly connected via a fixing flange 31 , thereby realizing a detachable connection between the liquid level pipe 2 and the liquid storage tank 1 .

[0024] A maintenance valve 4 is provided on the connecting pipe 3, and is located between the fixing flange 31 and the liquid storage tank 1. When the liquid level pipe 2 needs to be disassembled, the connection of the liquid storage tank 1 can be sealed by closing the maintenance valve 4 to prevent the liquid in the liquid storage tank 1 from flowing out.

[0025] In this embodiment, there are two connecting pipes 3, the upper part of the liquid level pipe 2 is fixedly connected to the upper part of the liquid storage tank 1 through one connecting pipe 3, and the lower part of the liquid level pipe 2 is fixedly connected to the lower part of the liquid storage tank 1 through another connecting pipe 3. Providing two connecting pipes 3 can make the liquid level pipe 2 easier to install, and can also ensure that the same liquid level as the liquid storage tank 1 is achieved.

[0026] The top of the liquid level tube 2 has a socket, and the rod type liquid level gauge A extends into the liquid level tube 2 from the socket. The socket has an internal thread that matches the external thread of the rod type liquid level gauge A, and the rod type liquid level gauge A is threadedly fixed to the socket. The bottom of the liquid level tube 2 has a drain port. The drain port is provided with a drain valve 5 for controlling the discharge of the liquid in the liquid level tube 2.

[0027] Specifically, an upper pipe cap 21 and a lower pipe cap 22 are welded and fixed to the top and bottom of the liquid level pipe 2, respectively, and an upper fixed joint 23 and a lower fixed joint 24 are welded and fixed to the upper pipe cap 21 and the lower pipe cap 22, respectively. The upper fixed joint 23 has a through hole, i.e., a socket, and the rod-type liquid level gauge A extends from the upper fixed joint 23 into the liquid level pipe 2 and is threadedly connected to the upper fixed joint 23. The lower fixed joint 24 also has a through hole, i.e., a drain port, and the drain valve 5 is threadedly fixed to the lower fixed joint 24.

[0028] The method of using the liquid storage device of the utility model which is easy to replace the long rod type liquid level gauge is as follows: fix the liquid level tube 2 with the rod type liquid level gauge A inserted to the liquid storage tank 1 through the connecting tube 3, close the drain valve 5, open the maintenance valve 4, and the liquid in the liquid storage tank 1 enters the liquid level tube 2 through the connecting tube 3 until the liquid levels in the liquid storage tank 1 and the liquid level tube 2 are the same. At this time, the liquid level in the liquid level tube 2 measured by the rod type liquid level gauge A is the liquid level in the liquid storage tank 1. When the liquid in the liquid storage tank 1 increases or decreases, the liquid level in the liquid level tube 2 changes accordingly, so the rod type liquid level gauge A inserted in the liquid level tube 2 can always measure the liquid level of the liquid in the liquid storage tank 1.

[0029] When the rod type liquid level gauge A needs to be repaired or replaced, close the maintenance valve 4 on each connecting pipe 3, open the drain valve, drain the liquid in the liquid level pipe 2, and then remove the liquid level pipe 2 with the rod type liquid level gauge A inserted from the liquid storage tank 1 as a whole by disassembling the fixing flange 31 on each connecting pipe 3. Figure 2 and 3 As shown. Finally, by placing the level tube 2 horizontally or tilted (not vertically), the rod-type liquid level gauge A therein can be replaced. Compared with inserting the rod-type liquid level gauge A directly and vertically into the liquid storage tank 1, the device can complete the installation of the rod-type liquid level gauge A without vertically raising the rod-type liquid level gauge A to the top of the liquid storage tank 1. On the basis of ensuring that the rod-type liquid level gauge A can work, it is more convenient for personnel to operate and is suitable for higher containers.
