It is mainly used to proportion, mix, or store multiple components according to a certain ratio or requirement to ensure the accuracy and efficiency of the production process. The liquid level control device for the batching tank is a device used to automatically monitor and adjust the liquid level of the liquid or material in the batching tank. Its main function is to ensure that the liquid level in the tank remains within a preset range, avoiding overflow or too low liquid level, thereby ensuring the stability and accuracy of the production process, especially in industrial applications that require precise batching and quantitative feeding of materials.

[0003] The existing liquid level control device generally uses a magnetic flap level gauge to measure the liquid height inside the batching tank. However, this method is relatively easily affected by impurities. Excessive impurities in the batching tank will affect the floating height of the float, thereby affecting the accuracy of observation. For this reason, we have proposed a new liquid level control device for the batching tank. Content of the Utility Model

Specific embodiments

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] As Figure 1-7 shown, the present utility model provides a technical solution: a batching tank liquid level control device, including a batching tank 1, a base 101, a filling head 102 and an output head 103. Three groups of bases 101 are fixedly welded to the lower end of the batching tank 1, a filling head 102 is arranged at the upper end of the batching tank 1, and an output head 103 is arranged at the lower end of the batching tank 1;

[0028] Two groups of connecting pipes 107 are fixedly welded to the right wall of the batching tank 1. The right walls of the two groups of connecting pipes 107 are respectively connected with a first flange interface 108. A second flange interface 109 is arranged on the right side of the first flange interface 108. The right side of the second flange interface 109 is connected with a filter tank 2 through a pipeline. The right end of the filter tank 2 is connected with a liquid level pipe 201 through a pipeline, and a supporting magnetic flap 202 is installed at the right end of the liquid level pipe 201;

[0029] Both ends of the filter tank 2 are respectively provided with connecting grooves 203. A filter cover 204 is arranged inside the filter tank 2. Two groups of cleaning brushes 207 are arranged on the inner wall of the filter tank 2. The cleaning brushes 207 are installed on the outer side of the filter cover 204. A connecting ring 210 is fixedly connected to the right end of the filter cover 204.

[0030] According to the overall structure of the device, the filter cover 204 can be used to filter impurities in the liquid transported into the liquid level tube 201, avoiding excessive impurities from affecting the float inside the liquid level tube 201 and causing problems such as reduced accuracy. At the same time, sewage can be discharged, which helps to keep the entire pipeline clean.

[0031] As Figure 3 As shown, a cylindrical groove is provided on the left wall of the output head 103 and a connecting sleeve 104 is arranged in the groove. A screw rod 105 is sleeved inside the connecting sleeve 104. The screw rod 105 is connected to the closing plate 106 through the inside of the connecting sleeve 104. The outer wall of the closing plate 106 is wrapped with rubber.

[0032] By arranging the closing plate 106 inside the output head 103 and controlling the inclination angle of the closing plate 106 by rotating the screw rod 105, the control of drainage can be realized.

[0033] As Figure 4 As shown, cylindrical grooves 110 are provided inside the first flange interface 108 and the second flange interface 109, and a sealing gasket 111 is arranged inside the cylindrical grooves 110.

[0034] By providing the cylindrical grooves 110 and arranging the sealing gasket 111, the sealing of the gap at the connection can be realized, avoiding liquid leakage at the connection.

[0035] As Figure 5 As shown, a sewage outlet 205 is provided on the lower wall of the filter tank 2, and a closing sleeve 206 is arranged inside the sewage outlet 205.

[0036] By providing the sewage outlet 205 on the lower wall of the filter tank 2 and arranging the closing sleeve 206 to seal the sewage outlet 205, the sewage discharge inside the filter tank 2 can be realized, which helps to keep the inside of the filter tank 2 clean.

[0037] As Figure 5 As shown, the outer shape of the filter cover 204 is cylindrical, and the filter cover 204 is installed at the connecting groove 203 provided on the right side inside the filter tank 2.

[0038] By installing the filter cover 204 at the right end inside the filter tank 2, the water outlet can be filtered through the filter cover 204.

[0039] As Figure 6As shown, an annular groove 208 is formed in the right wall of the filter tank 2, and the length from the center of the connection groove 203 to the annular groove 208 is greater than the radius length of the filter cover 204.

[0040] By designing that the length from the center of the connection groove 203 to the annular groove 208 is greater than the radius length of the filter cover 204, leakage of the formed annular groove 208 can be avoided.

[0041] As Figure 7 shown, a connecting rod 209 is installed inside the annular groove 208. One end of the connecting rod 209 is connected to the connecting ring 210. The connecting ring 210 is adapted to the inner size of the filter tank 2, and the inner ring radius of the connecting ring 210 is the same as the radius of the connection groove 203.

[0042] By connecting the connecting rod 209 and the connecting ring 210, and then the water outlet can be aligned with the connection groove 203 through the inner ring opening of the connecting ring 210 for water outlet. It can be realized that by moving the connecting rod 209 to rotate around the track of the annular groove 208 externally, the connecting ring 210 can be driven to rotate, so that the filter cover 204 can be brushed by the cleaning brush 207.

[0043] Working principle: This device can realize the observation and control of the liquid level inside the batching tank 1. The batching tank 1 is an existing device. At the same time, the liquid level tube 201 and the supporting magnetic flap 202 form a magnetic flap liquid level gauge. When the float inside the liquid level tube 201 rises or falls with the liquid level, the external supporting magnetic flap 202 can observe the liquid level height through the magnetic field change. The magnetic flap liquid level gauge is a relatively mature existing technology and will not be described in detail here; when observing the liquid level height inside the batching tank 1 by using the magnetic flap liquid level gauge, when the internal liquid is low, the corresponding liquid can be added through the filling head 102, and when the liquid level is too high, some liquid can be discharged through the output head 103; the liquid level height inside the batching tank 1 can be better controlled through the magnetic flap liquid level gauge; however, the impurities in the liquid will affect the accuracy of the magnetic flap liquid level gauge, so we need to filter the liquid and clean it regularly and periodically;

[0044] When the liquid passes through the connecting groove 203 into the interior of the filtration tank 2, the filter cover 204 filters the liquid inside the filtration tank 2, blocking larger impurities on the outer wall of the filter cover 204. After a certain filtration period, the interior of the filtration tank 2 can be drained through the drain port 205. At the same time, we can rotate the connecting rod 209 along the track of the annular groove 208. The connection between the connecting rod 209 and the connecting ring 210 drives the connecting ring 210 to rotate inside the filtration tank 2. The connection between the connecting ring 210 and the filter cover 204 drives the filter cover 204 to rotate. A cleaning brush 207 is arranged outside the filter cover 204 to clean the outer wall of the filter cover 204, and the internal impurities can be cleaned off, thus helping to keep the liquid entering the liquid level tube 201 clean and tidy.

[0045] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
