Description

Technical Field

[0001] This utility model belongs to the field of steel pickling technology, specifically relating to a steel pickling liquid level control device. Background Technology

[0002] Steel parts are metallic materials with iron as the main component. They are widely used in construction, machinery manufacturing, automobile industry and other fields. Pickling of steel parts is a common surface treatment process. It is mainly used to remove impurities such as oxide scale and rust from the surface of steel to improve its surface quality and corrosion resistance.

[0003] The pickling tank is a key piece of equipment in the pickling process of steel parts. Existing pickling tanks are equipped with float-type level switches to control the liquid level. However, the existing float-type level switches use a rotating structure. When the liquid level is low, the float moves down, driving the plug to rotate via a connecting rod, allowing the pickling liquid to flow into the pickling tank. When the liquid level is high, the float moves up, driving the plug to rotate via the connecting rod, sealing the outlet pipe. The rotating structure is prone to jamming, sticking, or falling off, which affects the control of the liquid level. Therefore, a steel pickling liquid level control device is proposed. The stainless steel float moves up and down with the liquid level, and the rubber plug directly seals the bottom of the outlet pipe. The structure is simple and not easily damaged. Summary of the Invention

[0004] In view of the shortcomings of the above-mentioned background technology, the purpose of this utility model is to provide a steel pickling liquid level control device, in which a stainless steel float moves up and down with the liquid level, and the bottom of the outlet pipe is directly sealed by a rubber stopper. The structure is simple and not easily damaged.

[0005] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: A steel pickling liquid level control device includes an outlet pipe, a structural block and an auxiliary upright. A structural plate is welded to one side of the outlet pipe, and an upright is sleeved through the inside of the structural plate. A stainless steel float ball is installed at the bottom end of the upright located at the bottom of the outlet pipe. A connecting pipe is welded to the other side of the water outlet pipe. A filter screen is fixed inside the connecting pipe by bolts. An internal threaded ring is welded to the bottom of the connecting pipe, and a transparent waste storage cylinder is installed at the bottom of the internal threaded ring.

[0006] By adopting the above technical solution, the upright is sleeved inside the structural plate, and the stainless steel float is fixed at the bottom of the upright, so that the upright can move up and down with the liquid level. When the stainless steel float moves up, it seals the bottom of the outlet pipe with a rubber stopper to stop the liquid supply. When the stainless steel float moves down, it allows the acid to flow out through the bottom of the outlet pipe for liquid supply.

[0007] Based on the above scheme and as a preferred option: a circular plate is welded inside the water outlet pipe, and through holes are equidistantly opened at the bottom of the circular plate.

[0008] Based on the above scheme and as a preferred option: a rubber plug is fixed to the top of the stainless steel float by bolts, a structural block is welded to one side of the stainless steel float, and the bottom of the upright is connected to the top of the structural block through a threaded groove.

[0009] Based on the above scheme and as a preferred option: an auxiliary upright is sleeved through the top of one side of the structural plate, and the bottom end of the auxiliary upright is connected to the top of the structural block through a threaded groove.

[0010] Based on the above scheme and as a preferred option, both the top of the upright and the auxiliary upright are fixed with limit blocks by bolts.

[0011] Based on the above scheme and as a preferred embodiment of the above scheme: a hexagonal ring is fixedly sleeved on the outside of the connecting pipe.

[0012] The outstanding and beneficial technical effects of this utility model compared to the prior art are: This utility model relates to a steel pickling liquid level control device. When the liquid level in the pickling tank is low, a stainless steel float moves downward, allowing the pickling liquid in the inlet pipe to fall through the connecting pipe into the outlet pipe and flow out from the bottom of the outlet pipe, thus adding pickling liquid into the pickling tank. When the liquid level in the pickling tank is high, the stainless steel float is pushed upward, causing the rubber plug at the top of the stainless steel float to insert into the outlet pipe, sealing the through hole on the circular plate and stopping the addition of pickling liquid, thereby achieving the purpose of controlling the liquid level.

[0013] The steel pickling liquid level control device of this utility model has a filter screen installed in the connecting pipe to filter the pickling liquid and prevent impurities in the pickling liquid from flowing into the through hole or rubber stopper, thereby avoiding blockage of the through hole or affecting the sealing efficiency of the rubber stopper.

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0016] The present invention provides a steel pickling liquid level control device, including a water outlet pipe 1, a structural block 6 and an auxiliary upright 14. A structural plate 3 is welded to one side of the water outlet pipe 1, and an upright 5 is sleeved through the inside of the structural plate 3. A stainless steel float ball 4 is provided at the bottom end of the upright 5 located at the bottom of the water outlet pipe 1. A connecting pipe 2 is welded to the other side of the water outlet pipe 1. A filter screen 10 is fixed inside the connecting pipe 2 by bolts. An internal threaded ring 11 is welded to the bottom of the connecting pipe 2. A transparent storage cylinder 12 is provided at the bottom of the internal threaded ring 11.

[0017] In use, the upright 5 is sleeved through the structural plate 3, and the stainless steel float 4 is fixed to the bottom of the upright 5, allowing the upright 5 to move up and down with the liquid level. When the stainless steel float 4 moves upward, it seals the bottom of the outlet pipe 1 through the rubber stopper 7, stopping the liquid supply. When the stainless steel float 4 moves downward, it allows the acid to flow out through the bottom of the outlet pipe 1 for liquid supply. The stainless steel float moves up and down with the liquid level, and the rubber stopper directly seals the bottom of the outlet pipe. The structure is simple and not easily damaged. Figure 1-3 As shown.

[0018] Furthermore, the present invention also includes a circular plate 8 welded inside the water outlet pipe 1, and through holes 9 are equidistantly opened at the bottom of the circular plate 8.

[0019] In use, the circular plate 8 is used to limit the rubber stopper 7, and the opening of the through hole 9 ensures that the circular plate 8 does not affect the flow of acid.

[0020] Furthermore, the present invention also includes a rubber plug 7 fixed to the top of the stainless steel float 4 by bolts, a structural block 6 welded to one side of the stainless steel float 4, and the bottom end of the upright 5 connected to the top of the structural block 6 by a threaded groove.

[0021] When in use, as the stainless steel float 4 moves upward, the rubber plug 7 is inserted into the bottom of the outlet pipe 1 to seal the through hole 9 on the circular plate 8.

[0022] Furthermore, such as Figure 3 As shown, this utility model also includes an auxiliary upright 14 that is sleeved through the top of the structural plate 3 on one side of the upright 5, and the bottom end of the auxiliary upright 14 is connected to the top of the structural block 6 through a threaded groove.

[0023] When in use, the auxiliary support rod 14 can prevent the stainless steel float 4 from rotating without affecting its up-and-down movement.

[0024] Furthermore, such as Figure 1 As shown, the present invention also includes limit blocks 15 that are fixed to the top of both the upright 5 and the auxiliary upright 14 by bolts.

[0025] When in use, the limiting block 15 prevents the upright 5 and the auxiliary upright 14 from falling off the structural plate 3.

[0026] Furthermore, such as Figure 3 As shown, the present invention also includes a hexagonal ring 13 fixedly sleeved on the outside of the connecting pipe 2.

[0027] When in use, the connecting tube 2 can be screwed onto the liquid outlet pipe by using a tool through the hexagonal ring 13.

[0028] When using this utility model, the operator screws one end of the connecting pipe 2 into the acid inlet pipe inserted into the pickling tank. When the liquid level in the pickling tank is low, the stainless steel float 4 moves downward, and the pickling liquid in the acid inlet pipe falls into the water outlet pipe 1 through the connecting pipe 2 and flows out from the bottom of the water outlet pipe 1, so that the pickling liquid is added into the pickling tank. When the liquid level in the pickling tank is high, the stainless steel float 4 is pushed upward, so that the rubber plug 7 at the top of the stainless steel float 4 is inserted into the water outlet pipe 1, which blocks the through hole 9 on the circular plate 8 and stops the addition of pickling liquid, thereby achieving the purpose of controlling the liquid level. A filter screen 10 is installed inside the connecting pipe 2 to filter the pickling solution and prevent impurities in the pickling solution from flowing into the through hole 9 or onto the rubber stopper 7, thereby preventing the through hole 9 from being blocked or affecting the sealing efficiency of the rubber stopper 7. The impurities filtered by the filter screen 10 fall into the transparent storage cylinder 12. The transparent storage cylinder 12 is screwed to the bottom of the internal thread ring 11 through a threaded groove and can be disassembled for emptying and cleaning. A hexagonal ring 13 is fixedly fitted on the outside of the connecting pipe 2, which is convenient for personnel to use tools to screw it on, making it easy to install the connecting pipe 2. The upright 5 is sleeved through the structural plate 3, so that the stainless steel float 4 can move up and down with the liquid level. The auxiliary upright 14 passes through the structural plate 3 and is fixed on the structural block 6 to limit the stainless steel float 4, preventing it from rotating without affecting its up and down movement.
