Description

Technical Field

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

[0002] Hydrochloric acid is an aqueous solution of hydrogen chloride (HCl), belonging to the category of monoprotic inorganic strong acids with wide industrial applications. Hydrochloric acid is a colorless, transparent liquid with a strong, pungent odor and high corrosiveness. Concentrated hydrochloric acid (mass fraction approximately %) is extremely volatile; therefore, when a container of concentrated hydrochloric acid is opened, hydrogen chloride gas evaporates and combines with water vapor in the air to produce small droplets of hydrochloric acid, creating an acid mist above the bottle opening. Filling machines are required when dispensing the produced hydrochloric acid solution.

[0003] Existing filling machines typically perform direct filling operations, cannot adjust the filling speed, and can only be used for one type of filling container, failing to adapt to the needs of different containers, resulting in low applicability and flexibility. Utility Model Content

[0004] To address the above problems, the present invention aims to provide a filling machine for hydrochloric acid production.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a filling machine for hydrochloric acid production, including a storage bin, an operating table, and a conveyor belt. The operating table is equipped with a control system, which controls the synchronous operation of the storage bin and the conveyor belt. The storage bin has an opening, a mounting base, and a reversing valve. The mounting base has a liftable plug, which is raised or lowered to open or close the opening. The reversing valve includes a valve body and a valve core rotatably disposed within the valve body. The valve body has a wide opening and a narrow opening, and the valve core has a drain port. Rotating the valve core aligns the drain port with the wide opening or the narrow opening to control the flow rate of hydrochloric acid discharged from the storage bin.

[0006] A further preferred embodiment of this utility model is that the diameter of the drain port is greater than the diameters of the wide and narrow openings.

[0007] A further preferred embodiment of this utility model is: a locking bolt is provided on the valve core, and a thread is provided in the valve body. When the valve core rotates to a suitable position in the valve body, the locking bolt is tightened to lock the valve core.

[0026] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0027] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0028] This embodiment mainly describes a filling machine for hydrochloric acid production, as detailed below:

[0029] A filling machine for hydrochloric acid production includes a support frame 9, on which a storage bin 8, an operating table 3, and a conveyor belt 5 are arranged. The operating table 3 is equipped with a control system, and the operating table 3 controls the opening or closing of the storage bin 8 and the conveyor belt 5 through electrical signals and sensors.

[0030] Storage compartment 8 contains hydrochloric acid to be filled. Hydrochloric acid is corrosive and dangerous. To prevent operators from being splashed by hydrochloric acid during the filling process, the operators use a slow filling method.

[0031] The storage chamber 8 has a U-shaped structure design, which allows the hydrochloric acid inside the storage chamber 8 to slide naturally down the inner wall of the storage chamber 8 under its own gravity, and will not accumulate in the storage chamber 8.

[0032] The storage compartment 8 is equipped with a mounting base 2, and a liftable striker 1 is installed inside the mounting base 2. The striker 1 is controlled by the control system in the operating console 3 and makes corresponding rising or falling movements according to the instructions of the control system.

[0033] The bottom of the storage chamber 8 is provided with an opening 11, which allows hydrochloric acid in the storage chamber 8 to flow out from the opening 11 for filling. The top of the firing pin 1 is fixedly provided with a plug 10, which is detachably provided at the end of the firing pin 1 for easy replacement after long-term use.

[0034] The diameter of the plug 10 is the same as the diameter of the opening 11, and the plug 10 is made of corrosion-resistant rubber. When the plug 10 descends with the impact pin 1 and blocks the opening 11, the rubber plug 10 undergoes elastic deformation to block the opening 11 and prevent hydrochloric acid in the storage chamber 8 from flowing out.

[0035] A reversing valve 7 is installed at the opening 11 of the storage chamber 8. After the hydrochloric acid in the storage chamber 8 flows through the reversing valve 7, it is filled by the filling container on the conveyor belt 5. The filling container can be a small-capacity glass bottle or a large-capacity polyethylene barrel or polypropylene barrel, depending on the needs.

[0036] The directional valve 7 is made of a corrosion-resistant alloy to extend its service life. The directional valve 7 includes a valve body 12, a valve core 18, and a valve stem 15. Specifically, the valve core 18 is rotatably disposed within the valve body 12, and a locking bolt 14 is provided on the valve core 18. Threads are provided on the inner wall of the valve body 12. When the valve core 18 rotates to a suitable position within the valve body 12, the locking bolt 14 is tightened to fix the position of the valve core 18. The valve stem 15 is fixedly disposed on the valve core 18, allowing the operator to rotate the valve core 18 via the valve stem 15.

[0037] The valve body 12 is provided with a wide opening 16 and a narrow opening 17 of different diameters, and the valve core 18 is provided with a drain port 13, the diameter of which is larger than that of the wide opening 16 and the narrow opening 17. The hydrochloric acid in the storage chamber 8 is filled through the drain port 13 and the wide opening 16 or the narrow opening 17 in sequence.

[0038] The valve stem 15 and the drain port 13 are staggered on the valve core 18 to prevent hydrochloric acid discharged from the reversing valve 7 from flowing onto the valve stem 15 and causing damage to the equipment.

[0039] Depending on the different rotational positions of the drain port 13 on the valve core 18 within the valve body 12, the reversing valve 7 can be divided into three modes. When the operator starts or ends the filling operation, the valve core 18 needs to be manually adjusted to the corresponding position. The three modes of the reversing valve 7 are as follows:

[0040] In the initial mode, the filling machine is in a non-started or finished filling state, and there is no hydrochloric acid or only a small amount of hydrochloric acid in the storage chamber 8. At this time, the drain port 13 on the valve core 18 is not aligned with the wide port 16 or the narrow port 17, and the small amount of hydrochloric acid in the storage chamber 8 cannot flow out from the reversing valve 7. In this state, the locking bolt 14 can be unscrewed to remove the valve core 18 from the valve body 12 for cleaning, washing away the hydrochloric acid remaining on the valve body 12 and the valve core 18, so as to extend the service life of the valve core 18 and the valve body 12.

[0041] In low-flow mode, the valve stem 15 rotates to the wide opening 16 side, aligning the drain port 13 on the valve core 18, which is staggered with the valve stem 15, with the narrow opening 17. The filling machine is in the start state, and the hydrochloric acid in the storage chamber 8 flows into the reversing valve 7 through the opening 11 in the storage chamber 8 and flows out from the narrow opening 17 through the drain port 13. At the same time, small-capacity filling containers are set on the conveyor belt 5 for filling.

[0042] In high-flow mode, the valve stem 15 rotates to the narrow opening 17 side, aligning the drain port 13 on the valve core 18, which is staggered with the valve stem 15, with the wide opening 16. The filling machine is in the start state, and the hydrochloric acid in the storage chamber 8 flows into the reversing valve 7 through the opening 11 in the storage chamber 8 and flows out through the drain port 13 from the wide opening 16. At the same time, a large-capacity filling container is set on the conveyor belt 5 for filling.

[0043] A pressure sensor 6 is installed under the conveyor belt 5, and a display screen 4 is installed on the control panel 3. Specifically, the pressure sensor 6 is located at the bottom of the conveyor belt 5, corresponding to the reversing valve 7. The operator sets a preset pressure value in the control system of the control panel 3. When the weight of the filling container reaches the preset pressure value, the pressure value is displayed on the display screen 4, the impact pin 1 descends, and the plug 10 at the top of the impact pin 1 blocks the opening 11 on the storage chamber 8, preventing the hydrochloric acid in the storage chamber 8 from flowing out. The conveyor belt 5 transports the filling container containing hydrochloric acid to the next stage. Then, the next filling container is sent to the reversing valve 7 via the conveyor belt 5, and the impact pin 1 drives the plug 10 to rise to start filling. The cycle repeats.
