Description

Technical Field

[0001] The invention relates to the technical field of flow measurement, in particular to a flow meter for a dye tank used for handicraft processing. Background Art

[0002] In order to improve the popularity of handicrafts during production and processing, it is necessary to spray dyes on the surface of handicrafts to make the surface smoother and more beautiful. Dyes are generally stored in dye tanks. In order to understand the remaining amount and usage of dyes in the dye tanks, a flow meter is needed to accurately measure the dye output from the dye tanks.

[0003] When the existing dye tank flow meter is in use, the contact time between the liquid dye and the measuring impeller is short, making it difficult to accurately measure the flow value and prone to errors. In addition, the flow meter has a single function and can only measure the flow rate, but cannot intercept the solid impurities contained in the liquid dye. As a result, the solid impurities can easily cause wear to the measuring impeller, further affecting the accuracy of the flow value. Summary of the invention

[0004] In view of this, the present invention provides a flow meter for a dye tank for handicraft processing to solve the problem that when the existing dye tank flow meter is in use, the contact time between the liquid dye and the measuring impeller is short, the flow value is prone to errors, and it is difficult to intercept solid impurities contained in the liquid dye. The solid impurities easily cause wear to the measuring impeller and affect the accuracy of the flow value.

[0005] The present invention provides a flow meter for a dye tank for handicraft processing, which specifically includes: a connecting pipe fitting; the connecting pipe fitting is connected to a feed pipeline, and the connecting pipe fitting is respectively connected to a measuring body and a filtering body; the interior of the measuring body is hollow, the liquid inlet end and the liquid outlet end of the measuring body are both connected to the connecting pipe fitting, and a digital flow meter is installed on the outside of the measuring body, and a measuring impeller is installed on the inside of the measuring body; a movable ratchet disk is installed on the outside of the measuring body, and the movable ratchet disk is connected to the measuring impeller; the interior of the filtering body is hollow, the liquid inlet end and the liquid outlet end of the filtering body are both connected to the connecting pipe fitting, and a filter screen is installed on the inside of the filtering body, and the filter screen divides the interior of the filtering body into two parts; a movable limit plate is installed on the outside of the filtering body, and the movable limit plate is connected to the connecting pipe fitting.

[0006] Furthermore, the liquid inlet and liquid outlet of the measuring body are located on the same side, the measuring impeller rotates inside the measuring body, and the measuring impeller is connected to a digital flow meter.

[0007] Furthermore, a fixed ratchet ring is provided on the outside of the measuring body, and a rotating shaft is provided at one end of the measuring impeller. The rotating shaft rotates on the outside of the measuring body. A sliding hole A is provided inside the movable ratchet disc. The movable ratchet disc is slidably connected to the rotating shaft through the sliding hole A. The movable ratchet disc is meshed with the fixed ratchet ring. A sliding groove is provided on the outside of the rotating shaft. A sliding block is provided inside the sliding hole A. The sliding block is slidably connected in the sliding groove.

[0008] Furthermore, a spring A is sleeved on the outside of the rotating shaft, and one end of the spring A is in contact with the movable ratchet disc.

[0009] Furthermore, the liquid outlet end of the filter body is connected to the liquid inlet end of the measuring body through a connecting pipe, and the filter screen installed inside the filter body is spiral-shaped.

[0010] Furthermore, the liquid inlet and outlet ends of the filter body are plugged into the connecting pipe, and the connecting pipe has four elastic hooks on the outside. The liquid inlet and outlet ends of the filter body are each provided with two clamping holes on the outside, and the elastic hooks are clamped in the clamping holes.

[0011] Furthermore, two sliding holes B are provided inside the movable limit plate, and the movable limit plate is slidably connected to the outside of the liquid inlet end and the liquid outlet end of the filter body through the sliding holes B, and the movable limit plate is in sliding contact with the inside of the elastic hook.

[0012] Furthermore, a spring B is mounted on the outer sides of the liquid inlet end and the liquid outlet end of the filter body, and one end of the spring B is in contact with the movable limit plate.

[0013] Beneficial effects: 1. The present invention makes the contact angle between the liquid dye inside the measuring body and the measuring impeller be 180°. The measuring impeller drives the internal measuring components of the digital flow meter to rotate, thereby achieving the flow measurement effect. The liquid dye needs to drive the measuring impeller to rotate 180° before it can be discharged, thereby extending the contact time between the liquid dye and the measuring impeller and improving the accuracy of flow measurement.

[0014] 2. In the present invention, when the liquid dye flows in the forward direction, the movable ratchet disc is affected by the meshing inclined surface with the fixed ratchet ring and moves outward along the rotating shaft. The spring A applies thrust to the movable ratchet disc, so that the movable ratchet disc is tightly meshed with the fixed ratchet ring, which has a one-way locking effect on the measuring impeller, thereby preventing the liquid dye inside the pipeline from flowing back through the measuring impeller; and the liquid dye entering the measuring body is filtered through the filter screen to prevent the solid impurities contained in the liquid dye from wearing the measuring impeller and affecting the flow measurement accuracy. The filter screen is designed in a spiral shape to increase the filtering area. Even if part of the filter screen is blocked, effective filtration can be achieved through the remaining filter screen to ensure the smooth flow of the liquid dye inside the pipeline.

[0015] 3. The present invention connects the filter body and the connecting pipe fitting together by means of plug-in and clip-on connection, so that the filter body can be replaced more easily. When the solid impurities intercepted by the filter screen inside the filter body are too many, the filter body can be disassembled and replaced. When the elastic hook is clipped into the clip hole, the movable limit plate is in sliding contact with the inner side of the elastic hook under the thrust of the spring B, which plays a supporting effect on the inner side of the elastic hook, preventing the elastic hook from bending and deforming inward, and ensuring the firmness of the connection between the filter body and the connecting pipe fitting. When the filter body needs to be disassembled and replaced, the movable limit plate is moved in the opposite direction to separate the movable limit plate from the elastic hook, and the filter body can be pulled to be disassembled, which is faster and more time-saving.
