Description

Technical Field

[0001] The utility model belongs to the technical field of fluoroboric acid production equipment, and specifically relates to a buffer tank for fluoroboric acid production. Background Art

[0002] Fluoroboric acid is an important raw material for the preparation of fluoroborates, especially for cleaning aluminum and its alloys before electroplating, electrolytic polishing of pure aluminum, removal of flux from low-activity metal substrates, and re-cleaning of electroplated parts. At present, the production method of fluoroboric acid is generally to dissolve refined boric acid in water to prepare a boric acid solution, and then put the boric acid solution in an ice water bath. At this time, hydrogen fluoride gas is introduced into the boric acid solution to obtain fluoroboric acid. The existing buffer tank for fluoroboric acid production will be injected with water after use to seal the fluoroboric acid tank. However, placing the fluoroboric acid tank directly into the buffer tank will cause the fluoroboric acid tank to float inside the buffer tank, causing the fluoroboric acid tank to float or shake, resulting in poor safety. Therefore, our company provides a buffer tank for fluoroboric acid production to solve the above technical problems. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figures 1 to 3As shown, an embodiment of the utility model provides a buffer tank for fluoroboric acid production, including a buffer tank body 6 and a mounting plate 14, roller sliders 12 are fixedly installed on the top of the mounting plate 14 near the left and right sides, electric telescopic rods 13 are fixedly installed on the top of the mounting plate 14 near the center, the output ends of the two electric telescopic rods 13 are highly connected with sealing covers 1, a mounting frame 2 is fixedly installed on the bottom of the sealing cover 1, a motor box 3 is fixedly installed on the left side of the mounting frame 2 near the bottom, and an equally spaced rotating rod 18 is fixedly connected to the output end of the motor box 3, a mounting groove 4 is opened at the bottom of the mounting frame 2, first slide bars 9 are fixedly installed on the left and right side walls of the mounting groove 4 near the front and rear ends, a plurality of first slides 10 are distributed side by side on the outer surfaces of the two first slide bars 9, and a clamping plate 11 is fixedly installed on the top of the plurality of first slides 10, a water inlet pipe 16 is fixedly connected to the left side of the buffer tank body 6 near the top, and a drain pipe 7 is fixedly connected to the right side of the buffer tank body 6 near the bottom.

[0022] Specifically in this embodiment, when in use, the packaged fluoroboric acid tank is placed between multiple clamping plates 11, and the forward and reverse motor 17 is started. The output end of the forward and reverse motor 17 drives the equally spaced rotating rod 18 to rotate, and the characteristics of the equally spaced rotating rod 18 are used to drive the first slide 10 to move toward the center along the first slide bar 9 until one side of the connecting plate 20 contacts the surface of the packaged fluoroboric acid tank. After the connecting plate 20 receives the pressure, it will push the connecting column 21 and the slide plate 22 to move along the second slide bar 23, thereby compressing the spring until the slide plate 22 contacts the sensing end of the pressure sensor 19. After sensing the pressure, the pressure sensor 19 electrically closes the output of the output end of the forward and reverse motor 17. Subsequently, the electric telescopic rod 13 is started, and the output end of the electric telescopic rod 13 moves downward, thereby driving the sealing cover 1 and the mounting frame 2 to move downward until the sealing cover 1 covers the buffer tank body 6. Subsequently, the buffer tank body 6 is filled with water through the water inlet pipe 16 until it contacts the water level sensor. The fluoroboric acid tank is in the buffer tank. When the fluoroboric acid tank is inside the main body 6, the clamping plate 11 clamps it, thereby preventing the fluoroboric acid tank from floating on the water surface. During the clamping process of the fluoroboric acid tank, if the fluoroboric acid tank and the clamping plate 11 become loose, the pressure of the slide plate 22 on the spring will also disappear, and the elastic force accumulated in the spring will push the slide plate 22, the connecting column 21 and the connecting plate 20 to be close to the electronic device to be detected, and the pressure on the pressure sensor 19 will also disappear. When the pressure sensor 19 cannot sense the pressure during the detection of the electronic device to be detected, it will electrically drive the output end of the forward and reverse motor 17 to rotate, thereby clamping the fluoroboric acid tank again, so that the connecting column 21 retracts into the interior of the mounting groove 4 again, and pushes the slide plate 22 again to compress the position of the spring along the direction of the slide rod until the top of the slide plate 22 contacts the bottom sensing end of the pressure sensor 19 again. After sensing the pressure, the pressure sensor 19 electrically closes the output end of the electric telescopic rod 13 again, thereby ensuring that the excessive clamping force does not cause damage to the fluoroboric acid tank.

[0023] See also Figures 1 to 3 As shown, roller guide rails 15 are provided inside the two roller sliders 12. The roller sliders 12 roll on the roller guide rails 15. Compared with sliding friction, rolling friction has less resistance, which can effectively reduce energy loss and wear. The roller guide rail 15 system can provide high-precision positioning and movement, because the diameter of the roller and the size of the track are strictly controlled, which can reduce motion errors.

[0024] See also Figures 1 to 3As shown, the end of the equally spaced rotating rod 18 away from the forward and reverse motor 17 is movably sleeved with a bearing seat 5, the end of the bearing seat 5 away from the equally spaced rotating rod 18 is fixedly connected to the inner right side wall of the mounting groove 4, the end of the equally spaced rotating rod 18 away from the bearing seat 5 penetrates the inner left side wall of the mounting groove 4 and the right side of the motor box 3, and is connected to the forward and reverse motor 17, the connection between the equally spaced rotating rod 18 and the mounting groove 4 and the motor box 3 is connected through a ball bearing, and the connection between the equally spaced rotating rod 18 and the mounting groove 4 and the motor box 3 is provided with a sealing ring. The purpose of providing the sealing ring is to prevent external substances such as dust and liquid from entering, keep the interior clean and reduce wear, and the provision of the ball bearing can make the friction coefficient lower, can withstand higher loads, and have a longer service life. By using the ball bearing, the friction between the equally spaced rotating rod 18 and the mounting groove 4 and the motor box 3 during the rotation process can be effectively reduced, thereby improving the efficiency and stability of the entire system.

[0025] See also Figures 1 to 3 As shown, control valves are provided on the water inlet pipe 16 and the drain pipe 7, a controller is provided on the buffer tank body 6, and the mounting frame 2 and the motor box 3 are movably connected to the inside of the buffer tank body 6. By adjusting the opening of the control valve, the flow rate and pressure of the fluid can be changed, thereby realizing the control and adjustment of the system operation state. The output ends of the two electric telescopic rods 13 pass through the top of the mounting plate 14 and extend out of the bottom of the mounting plate 14 and are fixedly connected to the top left and right sides of the sealing cover 1 near the center. When in use, start the electric telescopic rod 13, and move the output end of the electric telescopic rod 13 downward, thereby driving the sealing cover 1 and the mounting frame 2 to move downward until the sealing cover 1 covers the buffer tank body 6.

[0026] See also Figures 1 to 3 As shown, the outer surface of the equally spaced rotating rod 18 is provided with a plurality of equally spaced rotating grooves arranged in parallel, and the lower surfaces of the plurality of first slides 10 are respectively movably sleeved with the inner parts of the plurality of equally spaced rotating grooves on the equally spaced rotating rod 18.

[0027] See also Figures 1 to 3As shown, multiple clamping plates 11 are arranged inside the mounting frame 2, multiple clamping plates 11 are provided with placement grooves 8 on the left side, multiple placement grooves 8 are fixedly installed with second slide bars 23 groups near the four corners on the left and right side walls, multiple second slide bars 23 groups are movably sleeved with slide plates 22 on the outer surfaces, multiple slide plates 22 are fixedly installed with connecting columns 21 on the left side, multiple connecting columns 21 are fixedly connected with connecting plates 20 on the left side, multiple placement grooves 8 are fixedly installed with springs near the center of the right side walls, multiple placement grooves 8 are fixedly installed with pressure sensors 19 at the center of the right side walls, multiple connecting columns 21 respectively penetrate multiple placement grooves 8 and extend out of the left side of multiple clamping plates 11, multiple connecting columns 21 are respectively connected with the inside of multiple placement grooves 8 in a movably sleeved manner, and sealing rings are provided at the connection between the connecting columns 21 and the placement grooves 8.
