Description

Technical Field

[0001] The utility model belongs to the field of baking soda production equipment, and specifically relates to a thickener for baking soda production. Background Art

[0002] When baking soda is produced, the concentrated liquid containing salt crystals enters the thickener and settles and separates in the thickener. The upper clear liquid is first discharged to the mother liquid tank and then returned to the crystallizer for heating and concentration, while the crystals that settle to the bottom are discharged from the bottom of the thickener. When the existing thickener discharges the clear liquid, part of the separated crystals will be taken out, which reduces the working efficiency of the thickener and affects the efficiency and quality of crystal separation. Utility Model Content

[0003] In order to solve the deficiencies of the prior art, the utility model aims to provide a thickener for baking soda production, which can reduce the crystal content in the extracted clear liquid, thereby significantly improving the production efficiency of baking soda.

[0020] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not intended to limit the scope of use of the present invention.

[0021] like Figure 1-3 As shown, the utility model proposes a thickener for baking soda production, including a tank body 1 and a liquid pump 4. The outer disk of the tank body 1 is provided with a cooling pipe, and the cooling pipe is connected to an external coolant supply device, so as to cool the solution in the tank body 1 and accelerate the precipitation of crystals.

[0022] A lifting plate 3 is provided inside the tank body 1 to move horizontally and cooperate with the inner wall of the tank body 1. A hydraulic cylinder 2 is installed vertically downward on the top of the tank body 1. The piston rod of the hydraulic cylinder 2 is fixedly connected to the lifting plate 3, so that the lifting plate 3 can be driven to move up and down close to the inner wall of the tank body 1. Among them, a circular cavity 30 is provided inside the lifting plate 3, and a plurality of fan-shaped notches 31 are vertically penetrated on the lifting plate 3. The notches 31 are arranged at equal angles with the center of the lifting plate 3 as the center, and the notches 31 are connected to the cavity 30; a through hole 32 connected to the cavity 30 is provided at the center of the lifting plate 3, and a first cylinder 7 is rotatably installed in the through hole 32. A plurality of fan-shaped filter screens that cooperate with the notches 31 are provided horizontally and movably in the cavity 30, and the fan-shaped filter screens are fixedly connected to the outer wall of the first cylinder 7. The rotation of the first cylinder 7 can drive the fan-shaped filter screen to rotate out of the cavity 30, thereby filling the corresponding notches 31. A positioning plate 33 is fixedly provided on the side surface of each notch 31 in the same direction. When the fan-shaped filter rotates between the cavity 30 and the notch 31, the positioning plate 33 can effectively position the rotation stop position of the fan-shaped filter, so that the fan-shaped filter can completely fill the notch 31. As the lifting plate 3 moves downward, the clear liquid can pass through the fan-shaped filter, thereby realizing effective separation of crystals and clear liquid.

[0023] The top of the tank body 1 is provided with a rotating mechanism that cooperates with the first cylinder body 7 and is used to drive the fan-shaped filter to rotate. In this embodiment, the rotating mechanism includes a second cylinder body 5, a rotating rod 6 and a motor 8. The second cylinder body 5 is vertically installed on the top of the tank body 1. The second cylinder body 5 corresponds to the first cylinder body 7 and is rotatably installed on the top of the tank body 1. The upper end of the second cylinder body 5 is connected to the motor 8, and the motor 8 is a forward and reverse motor 8. The rotating rod 6 is coaxially slidably clamped in the second cylinder body 5. The top of the second cylinder body 5 is closed and a spring 52 is provided inside to abut against the rotating rod 6. Specifically, a slide groove 51 is opened on the inner wall of the second cylinder body 5 along the length direction, and a limit block 62 is fixed on the side wall of the rotating rod 6. The limit block 62 and the sliding card are set in the slide groove 51, and then under the cooperation of the limit block 62 and the slide groove 51, the rotating rod 6 can be telescopically movable up and down in the second cylinder body 5. The plug 61 is provided at the lower end of the rotating rod 6 extending out of the second cylinder body 5. A socket 70 is provided at the upper end of the first cylinder 7, and the socket 70 is plugged with the plug 61. In this embodiment, the socket 70 and the plug 61 are square in design. When the lifting plate 3 drives the first cylinder 7 to move upward, the plug 61 of the rotating rod 6 can be plugged into the socket 70 of the first cylinder 7. When the motor 8 drives the second cylinder 5 and the rotating rod 6 to rotate, the fan-shaped filter screen is driven by the first cylinder 7 to rotate out to fill the gap 31 or rotate back into the cavity 30. When the first cylinder 7 moves upward and the socket 70 is not docked with the plug 61, the rotating rod 6 will first abut against the outer edge of the socket 70 and compress the spring 52. As the motor 8 drives the second cylinder 5 and the rotating rod 6 to rotate, the plug 61 can be rotated to align with the socket 70 and then inserted into it, thereby realizing the effective docking of the rotating rod 6 and the first cylinder 7.

[0024] The liquid pump 4 is installed above the tank body 1, the liquid outlet of the liquid pump 4 is connected to the recovery pipe 42, the liquid inlet pipe 11 of the liquid pump 4 is connected to the infusion hose 41, and the liquid inlet end of the infusion hose 41 is fixed on the top of the lifting plate 3, which can effectively and completely suck out the clear liquid above.

[0025] The liquid inlet pipe 11 of the tank body 1 is arranged at the top of the tank body 1, and the liquid inlet pipe 11 of the tank body 1 is arranged corresponding to one of the notches 31 on the lifting plate 3. After the fan-shaped filter screen is retracted into the cavity 30, the liquid inlet pipe 11 can inject liquid into the tank body 1 through the notch 31 to prevent the solution from falling directly on the lifting plate 3 and reduce the precipitation of crystals on the lifting plate 3.

[0026] A discharge port 12 with a control valve 121 is provided at the bottom of the tank body 1. The discharge port 12 can be opened by the control valve 121 to effectively discharge the precipitated crystals.

[0027] When using the utility model, firstly, the lifting plate 3 is lifted to the top of the tank body 1 by the hydraulic cylinder 2, and the motor 8 drives the second cylinder 5, the rotating rod 6 and the first cylinder 7 to rotate, so that the fan-shaped filter is rotated and retracted into the cavity 30 of the lifting plate 3 to avoid affecting the liquid inlet; the untreated solution is injected into the tank body 1 through the gap 31 through the liquid inlet pipe 11, and the crystals are separated from the clear liquid under the cooling effect of the cooling pipe; the motor 8 flips, thereby driving the fan-shaped filter to rotate out of the cavity 30 and close the gap 31; the hydraulic cylinder 2 drives the lifting plate 3 to move slowly downward and press on the crystals precipitated below, while the clear liquid passes through the fan-shaped filter and is above the lifting plate 3; the liquid pump 4 is started, and the clear liquid in the tank body 1 can be extracted through the infusion hose 41, and the control valve 121 is opened to discharge the precipitated crystals from the discharge port.
