Description

Technical Field

[0001] The utility model relates to the technical field of industrial instrument application, and more particularly to a heating device for a magnetic flap liquid level gauge. Background Art

[0002] Existing magnetic flap level gauges are used in desalted water tanks for flue gas denitrification (FNOx) in power generation boilers. They monitor the water level in the desalted water tank, display the level locally, and transmit the level signal to a remote monitoring computer, allowing control room personnel to remotely control the tank's level by replenishing water. The magnetic flap level gauge consists of a main body, a flap housing (composed of small red and white magnetic flaps), a float, a transmitter, and a flange cover. Operating based on the principle of buoyancy, the float moves up and down within the measuring tube as the liquid level rises. The permanent magnets within the float, through magnetic coupling, drive the red and white flaps to flip 180 degrees. As the liquid level rises, the flaps turn from white to red, and as the liquid level falls, they turn from red to white, thereby indicating the liquid level. The transmitter consists of a sensor and a converter. The up-and-down movement of the magnetic float, through magnetic coupling, sequentially activates measuring elements within the tube, generating a resistance signal that is converted into a standard current signal of 0-10 or 4-20 mA for output. This signal is then connected to a digital display instrument or computer for remote display and control.

[0003] During the use of existing magnetic flap level gauges, the desalted water will not freeze due to the high ambient temperature in spring, summer and autumn, and the float inside the magnetic flap level gauge can move freely up and down in the measuring tube according to the liquid level. When the temperature is below -4°C in winter, the desalted water in the measuring tube is prone to freezing due to lack of flow, making the float unable to move and the liquid level in the tank unable to be accurately displayed. This will cause the desalted water tank to be insufficiently replenished due to water shortage or excessive replenishment and overflow, affecting the normal production of the system. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that in the use of the existing magnetic flap liquid level gauge, the desalted water will not freeze due to the high ambient temperature in spring, summer and autumn, and the internal float of the magnetic flap liquid level gauge can move freely up and down in the measuring tube according to the liquid level height. When the temperature is below -4°C in winter, the desalted water in the measuring tube is prone to freezing due to lack of flow, which makes the float unable to move and the liquid level in the tank unable to be accurately displayed, resulting in the desalted water tank not being replenished in time and being short of water or being over-replenished and overflowing, thus affecting the normal production of the system. A specimen storage device for urology surgery is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solution: a specimen storage device for urology surgery, including a desalted water tank, a measuring tube is provided on the outer wall of the desalted water tank through a connecting pipe, and a float is provided on the inner wall of the measuring tube.

[0006] As a further description of the above technical solution:

[0007] A flap box is arranged on the outer wall of the measuring tube, a transmitter is arranged at the bottom of the measuring tube, and a heating tape is arranged on the outer wall of the measuring tube.

[0008] As a further description of the above technical solution:

[0009] The heating tape is provided with an on-site operation box via a connecting wire, and both ends of the heating tape are provided with fixing components.

[0010] As a further description of the above technical solution:

[0011] The fixing assembly includes a connecting plate, and the connecting plate is fixedly installed at both ends of the heating tape.

[0012] As a further description of the above technical solution:

[0013] A connecting block is rotatably mounted on the outer wall of the connecting plate, and a second clamping plate and a first clamping plate are fixedly mounted on the outer wall of the connecting block.

[0014] As a further description of the above technical solution:

[0015] A first fixing block is fixedly mounted on the side wall of the first clamping plate, and a pin hole is provided on the top surface of the first fixing block.

[0016] As a further description of the above technical solution:

[0017] A second fixing block is fixedly mounted on the side wall of the second clamping plate, and a pressure rod is slidably mounted on the inner wall of the second fixing block.

[0018] As a further description of the above technical solution:

[0019] An integrated board is fixedly mounted on the top of the pressure rod, and a latch is fixedly mounted on the bottom of the integrated board.

[0020] As a further description of the above technical solution:

[0021] A pull rod is fixedly installed on the top surface of the integrated board, and a spring is sleeved on the outer wall of the pressure rod.

[0022] As a further description of the above technical solution:

[0023] One end of the spring is fixedly mounted on the outer wall of the pressure rod, and the other end of the spring is fixedly mounted on the inner wall of the top of the second fixing block.

[0024] Compared with the existing technology, the beneficial effects of this solution are as follows:

[0025] 1. This solution sets up heating cables, an on-site operation box, and a computer. First, use glue or a pipe clamp to fix the electric heating cables from top to bottom on the outer wall of the measuring tube of the magnetic flap level gauge, and wrap 2-3 turns of heating cables around the water inlet pipe at the lower end of the magnetic flap level gauge. Remove the excess heating cables, install the on-site control box, connect the installed electric heating cables' power cords to the on-site operation box, lay the remote control cable, connect the control signals to the DCS control system, and control the program and operation screens on the main computer. This design effectively adds a heating device to the outer wall of the measuring tube without changing all the structures of the existing magnetic flap level gauge. This prevents the desalted water in the measuring tube from freezing in severe winter weather, allowing the float to move normally and accurately measure the liquid level.

[0026] 2. This solution sets a fixed component, pulls the pull rod outward, the pull rod drives the integrated plate to move, and the integrated plate drives the pin to move, so that it moves out of the pin hole set on the first fixed block. At the same time, the integrated plate drives the pressure rod to move, squeezing the spring to form a compressed state, and then rotates the first and second splints to open them, and then puts the first and second splints on the measuring tube, so as to loosen the pull rod and reinsert the pin into the pin hole set on the first fixed block by the elastic force of the spring. Through this design, the magnetic flap liquid level gauge heating device is effectively made to have a simple equipment structure, easy installation, low equipment cost and good use effect.
