AI Technical Summary
When measuring the level of PVDC emulsion, existing float level gauges often suffer from emulsion adhesion to the inner wall or float, leading to decreased detection accuracy.
The system employs a combination of a lifting ring, an infrared sensor, an infrared distance sensor, and an infrared receiver. It measures the liquid level using infrared light, and combines this with a pointer and a measuring scale to achieve liquid level detection. The system uses a drive motor to raise and lower the lifting ring, and guide wheels to achieve automated measurement.
It enables accurate detection of PVDC emulsion levels, has a simple structure, is easy to operate, saves manpower and resources, and improves work efficiency.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of liquid level detection technology, and in particular to a liquid level detection device for PVDC emulsion production. Background Technology
[0002] Polyvinylidene chloride (PVDC)[2] is a polymer of vinylidene chloride (1,1-dichloroethylene). Its English abbreviation is PVDC. Its glass transition temperature is -17℃, its melting temperature is 198~205℃, and its crystal density is 1.96 g / cm3. It has the characteristics of flame retardancy, corrosion resistance, and good airtightness. Due to its strong polarity, it is insoluble in common solvents at room temperature.
[0003] The float level gauge operates on the principles of buoyancy and magnetic coupling. As the liquid level rises (falls), the magnetic float inside the measuring cylinder drives the dual-color flip column on the external display to rotate 180° to display red (and 180° in the opposite direction to display white), thus achieving the purpose of measuring and displaying the position of the liquid level.
[0004] When existing float level gauges measure the level of emulsions, the emulsion easily enters the level chamber and adheres to the inner wall or the float, hindering the movement of the float and thus reducing the accuracy of level detection. Summary of the Invention
[0005] In view of this, the purpose of this utility model is to provide a liquid level detection device for PVDC emulsion production that can realize the function of PVDC emulsion liquid level detection.
[0006] This utility model is implemented using the following method: A liquid level detection device for PVDC emulsion production includes a supporting base plate, on which a storage tank is mounted. A measuring plate is bolted to the right end of the upper surface of the supporting base plate, and the measuring plate is perpendicular to the supporting base plate. A lifting component is mounted on the measuring plate, and a lifting ring is connected to the lifting component. The lifting ring is sleeved on the storage tank, and guide wheels are provided at both ends of the inner side of the lifting ring. A fixing block is provided at the right end of the lower surface of the lifting ring. An infrared sensor is provided on the left side of the fixing block, and an infrared distance sensor is provided on the lower surface of the fixing block. A supporting block is provided at the lower end of the left side of the measuring plate, and an infrared receiver corresponding to the infrared distance sensor is provided on the upper surface of the supporting block. A pointer is provided on the right side of the lifting ring, and a measuring scale corresponding to the pointer is provided on the right end of the front of the measuring plate.
[0007] Furthermore, the lifting component includes a drive motor, and a strip-shaped groove is provided on the left side of the front of the measuring plate. The drive motor is embedded in the bottom of the strip-shaped groove. The output end of the drive motor is connected to a screw, and a sliding block is spirally sleeved on the screw. The front of the sliding block is connected to the lifting ring.
[0008] The beneficial effects of this utility model are as follows: This utility model incorporates a lifting ring, an infrared sensor, an infrared distance sensor, a measuring scale, and an infrared receiver into the device, which enables the measurement of the liquid level of PVDC emulsion in the storage tank, thereby achieving the detection of the liquid level of PVDC emulsion; This utility model has a simple structure, is easy to operate, and can effectively save manpower and material resources and improve work efficiency. Attached Figure Description
[0009] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation
[0010] The present invention will be further described below with reference to the accompanying drawings.
[0011] Please see Figure 1 As shown, this utility model provides an embodiment: a liquid level detection device for PVDC emulsion production, including a supporting base plate 1, a storage tank 2 disposed on the supporting base plate 1, a measuring plate 3 bolted to the right end of the upper surface of the supporting base plate 1, the measuring plate 3 being perpendicular to the supporting base plate 1, a lifting component 4 disposed on the measuring plate 3, a lifting ring 5 connected to the lifting component 4, the lifting ring 5 being sleeved on the storage tank 2, and guide wheels 51 disposed at both ends of the inner side of the lifting ring 5, a fixing block 52 disposed at the right end of the lower surface of the lifting ring 5, an infrared sensor 53 disposed on the left side of the fixing block 52, an infrared distance sensor 54 disposed on the lower surface of the fixing block 52, a supporting block 55 disposed at the lower end of the left side of the measuring plate 3, an infrared receiver 56 corresponding to the infrared distance sensor 54 disposed on the upper surface of the supporting block 55, a pointer 57 disposed on the right side of the lifting ring 5, and a measuring scale 58 corresponding to the pointer 57 disposed on the right end of the front of the measuring plate 3. This allows for the storage of PVDC emulsion through the storage tank 2. The lifting component 4 drives the lifting ring 5 to move up and down. The guide wheel 51 facilitates the up and down movement of the lifting ring 5. The infrared distance sensor 54 and the infrared receiver 56 work together to transmit the measured distance data to a control platform. Then, the pointer 57 and the measuring scale 58 can detect the liquid level in real time. Since PVDC emulsion is opaque, the infrared light from the infrared sensor 53 penetrates to indicate that the liquid level has been reached. The storage tank 2 is transparent, thus enabling the detection of the PVDC emulsion liquid level.
[0012] Please continue reading. Figure 1 As shown in one embodiment of this utility model, the lifting component 4 includes a drive motor (not shown). A strip-shaped groove 41 is provided on the left side of the front of the measuring plate 3. The drive motor is embedded in the bottom of the groove 41. The output end of the drive motor is connected to a screw 42. A sliding block (not shown) is spirally sleeved on the screw 42. The front of the sliding block is connected to the lifting ring 5. This allows the drive motor to drive the screw 42 to rotate, which in turn causes the sliding block to move up and down, thereby enabling the lifting ring 5 to move up and down until it reaches the emulsion level in the storage tank 2, facilitating measurement.
[0013] In this utility model, the drive motor, infrared sensor, infrared distance sensor, and infrared receiver are all existing technologies, which can be clearly understood by those skilled in the art, and will not be described in detail here. The infrared distance sensor may be a GP2D120X, which is a Sharp infrared distance sensor, or an STM32, but is not limited to these.
[0014] The above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall be covered by the present utility model.
