Description

Technical Field

[0001] This utility model relates to the field of hydrochloric acid production technology, specifically to a filling machine for hydrochloric acid production. Background Technology

[0002] Hydrochloric acid, as an important inorganic chemical raw material, is widely used in various fields such as chemical industry, metallurgy, pharmaceuticals, and food processing. After the hydrochloric acid production process is completed, it needs to be diverted and filled, thus requiring the use of filling machines.

[0003] Currently, when filling hydrochloric acid, a conveying device moves the hydrochloric acid bottle below the filling tube, which then moves downwards to enter the bottle and fill it with hydrochloric acid. During the filling process, the filling tube gradually moves upwards. After filling is complete, the valve closes, and the filling tube moves upwards to its original position. However, in actual use, hydrochloric acid remains inside the filling tube after the filling stops. This residual hydrochloric acid not only wastes materials and pollutes the environment, but more seriously, it corrodes the equipment. Therefore, it is necessary to improve the hydrochloric acid production filling machine to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a filling machine for hydrochloric acid production to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a filling machine for hydrochloric acid production, comprising a filling chamber, a door on the front of the filling chamber, a control panel on the front of the door, a filling mechanism inside the filling chamber, and a fixing mechanism extending from the interior of the filling chamber to the exterior.

[0006] The filling mechanism includes a lifting assembly and a spill prevention assembly. The lifting assembly is located inside the filling chamber, and the spill prevention assembly is located outside the lifting assembly.

[0007] The lifting assembly includes a fixed box, which is fixedly installed inside the filling chamber. A motor is fixedly installed on the bottom inner side of the fixed box, and a threaded rod is fixedly installed on the output end of the motor. A sliding frame is slidably installed on the front of the fixed box, and multiple mounting plates are fixedly installed on the front of the sliding frame. A filling tube is fixedly installed inside the mounting plate, and a solenoid valve is fixedly installed on the filling tube. An inlet pipe is provided at the top of the filling tube to facilitate the lifting and lowering of the filling tube so that it can be inserted into the hydrochloric acid bottle for filling hydrochloric acid.

[0008] Preferably, the end of the threaded rod away from the motor is rotatably mounted on the top inner wall of the fixed box, and the threaded rod is threaded inside the sliding frame, so that the threaded rod can drive the sliding frame to slide.

[0009] Preferably, the front of the fixed box is provided with a sliding groove, and the sliding frame is slidably installed inside the sliding groove, so that the sliding frame can slide through the fixed box.

[0010] Preferably, the anti-flow component includes an air blowing ring, which is fixedly installed on the outside of the filling tube. An air supply pipe is fixedly installed on the outside of the air blowing ring. An air pump is fixedly installed on the right side of the fixed box. An air inlet pipe is fixedly installed on the outside of the air pump. A one-way valve is provided on the air supply pipe to facilitate blowing inert gas into the filling tube after filling is completed, so that the residual hydrochloric acid inside is blown into the hydrochloric acid bottle, thus preventing residue from dripping onto the equipment.

[0011] Preferably, the inner side of the air blowing ring and the filling tube are provided with a plurality of downwardly inclined air holes, and the air holes are arranged in a circumferential array to facilitate the blowing off of hydrochloric acid remaining on the inner wall of the filling tube.

[0012] Preferably, the fixing mechanism includes a conveyor, which extends to two inside the filling chamber. A mounting frame is fixedly installed on the front of the conveyor, and two cylinders are fixedly installed on the back of the mounting frame and the inner wall of the front of the fixing box. A clamping plate is fixedly installed on the inner telescopic end of the cylinder, and multiple clamping rings are fixedly installed on the inner side of the clamping plate to facilitate the conveying of the hydrochloric acid bottle and its fixing during filling.

[0013] Preferably, the cylinder, clamping plate, and clamping rings are symmetrically arranged, and the positions of the multiple clamping rings correspond one-to-one with the multiple filling tubes, so that the clamping rings can fix the hydrochloric acid bottle at the filling tube.

[0014] Compared with the prior art, this utility model provides a filling machine for hydrochloric acid production, which has the following beneficial effects: 1. This hydrochloric acid production filling machine, through its filling mechanism, uses a lifting component to move the filling tube up and down during use, filling the hydrochloric acid bottle with hydrochloric acid. After filling is completed, an air pump injects inert nitrogen into the filling tube, which blows any remaining hydrochloric acid drops into the hydrochloric acid bottle, thus preventing hydrochloric acid drops from remaining inside the filling tube and dripping down.

[0015] 2. This hydrochloric acid production filling machine, through the setting of a fixing mechanism, transports hydrochloric acid bottles through a set of conveyors during use. When the bottles are transported to a fixed position, the cylinders at both ends drive the clamping rings on both sides to move inward, so that the clamping rings on both sides clamp and fix the hydrochloric acid bottles. After filling is completed, the clamping rings are released, and the bottles are transported to the right side by the conveyor. Attached Figure Description

Figure 1-8 This utility model provides a technical solution: a filling machine for hydrochloric acid production, including a filling chamber 1, a door 2 on the front of the filling chamber 1, a control panel 3 on the front of the door 2, a filling mechanism 4 inside the filling chamber, and a fixing mechanism 5 extending from the inside of the filling chamber 1 to the outside.

[0021] The filling mechanism 4 includes a lifting assembly 41 and a flow-prevention assembly 42. The lifting assembly 41 is located inside the filling chamber 1, and the flow-prevention assembly 42 is located outside the lifting assembly 41.

[0022] The lifting assembly 41 includes a fixed box 411, which is fixedly installed inside the filling chamber 1. A motor 412 is fixedly installed on the bottom inner side of the fixed box 411. A threaded rod 413 is fixedly installed on the output end of the motor 412. A sliding frame 414 is slidably installed on the front of the fixed box 411. Multiple mounting plates 415 are fixedly installed on the front of the sliding frame 414. A filling tube 416 is fixedly installed inside the mounting plate 415. A solenoid valve 417 is fixedly installed on the filling tube 416. An inlet pipe 418 is provided at the top of the filling tube 416 to facilitate the lifting and lowering of the filling tube 416 so that it can be inserted into the hydrochloric acid bottle for filling hydrochloric acid.

[0023] Furthermore, the end of the threaded rod 413 away from the motor 412 is rotatably mounted on the top inner wall of the fixed box 411, and the threaded rod 413 is threadedly mounted inside the sliding frame 414, so that the threaded rod 413 can drive the sliding frame 414 to slide.

[0024] Furthermore, a sliding groove is provided on the front of the fixed box 411, and the sliding frame 414 is slidably installed inside the sliding groove, so that the sliding frame 414 can slide through the fixed box 411.

[0025] Furthermore, the anti-flow component 42 includes an air blowing ring 421, which is fixedly installed on the outside of the filling tube 416. An air supply pipe 422 is fixedly installed on the outside of the air blowing ring 421. An air pump 423 is fixedly installed on the right side of the fixed box 411. An air inlet pipe 424 is fixedly installed on the outside of the air pump 423. A one-way valve 425 is provided on the air supply pipe 422 to facilitate blowing inert gas into the filling tube 416 after filling is completed, so as to blow the residual hydrochloric acid inside into the hydrochloric acid bottle and prevent the residue from dripping onto the equipment.

[0026] Furthermore, multiple downward-sloping air holes are provided on the inner side of the air blowing ring 421 and on the filling tube 416, and the air holes are arranged in a circumferential array to facilitate the blowing off of hydrochloric acid remaining on the inner wall of the filling tube 416. Example

[0027] To achieve the purpose of conveying and securing hydrochloric acid bottles during filling, this utility model provides another embodiment. Please refer to [link / reference needed]. Figure 9 Furthermore, in conjunction with Embodiment 1, the fixing mechanism 5 includes a conveyor 51, which extends to two inside the filling chamber 1. A mounting frame 52 is fixedly installed on the front of the conveyor 51. Two cylinders 53 are fixedly installed on the back of the mounting frame 52 and on the inner wall of the front of the fixing box 411. A clamping plate 54 is fixedly installed on the inner telescopic end of the cylinder 53. Multiple clamping rings 55 are fixedly installed on the inner side of the clamping plate 54 to facilitate the conveying of the hydrochloric acid bottle and its fixing during filling.

[0028] Furthermore, the cylinder 53, clamping plate 54, and clamping ring 55 are symmetrically arranged, and the positions of multiple clamping rings 55 correspond one-to-one with multiple filling tubes 416, so that the clamping rings 55 can fix the hydrochloric acid bottle at the filling tube 416.

[0029] In this invention, the filling chamber 1 is equipped with an exhaust device to centrally discharge the hydrochloric acid regeneration gas extending inside. At the same time, in this invention, the parts and structures that come into direct contact with hydrochloric acid (such as the filling pipe 416, the solenoid valve 417, the liquid supply pipe, etc.) are all made of hydrochloric acid corrosion resistant materials.

[0030] In actual operation, when this device is used, the inlet pipe 418 is connected to the hydrochloric acid supply pump, and the air inlet pipe 424 is connected to the nitrogen supply equipment. During the filling process, the hydrochloric acid bottle is conveyed to the right by the conveyor 51. When the hydrochloric acid bottle moves to the bottom of the filling pipe 416, the clamping plate 54 is driven to move inward by the cylinders 53 on both sides, so that the clamping plate 54 drives the inner clamping ring 55 to move inward, so that the clamping rings 55 on both sides clamp and fix the hydrochloric acid bottle. Subsequently, the motor 412 drives the threaded rod 413 to rotate, causing the threaded rod 413 to drive the sliding frame 414 to slide downwards. The sliding frame 414, via the mounting plate 415, moves the filling tube 416 downwards, inserting it into the hydrochloric acid bottle. Then, the solenoid valve 417 opens, and the filling tube 416 injects hydrochloric acid into the bottle. During the filling process, as the liquid level inside the hydrochloric acid bottle rises, the motor 412 drives the threaded rod 413 to reverse, causing the filling tube 416 to gradually move upwards. Once sufficient hydrochloric acid has been filled, the air pump 423 is started. Nitrogen gas is forced into the air-blowing ring 421 by the air supply pipe 422 on 423, and the nitrogen gas is blown into the interior of the filling tube 416 through the air-blowing ring 421 and the air hole on the filling tube 416. This blows the residual hydrochloric acid on the inner wall of the filling tube 416 into the hydrochloric acid bottle. Then the air pump 423 is turned off, and the filling tube 416 is driven to move upward and reset by the motor 412. The cylinder 53 drives the clamping ring 55 to reset and release the hydrochloric acid bottle. Then the conveyor 51 transports the filled hydrochloric acid bottle to the right and moves the empty bottle on the left to the bottom of the filling tube 416.
