Description

Technical Field

[0001] This utility model relates to the field of soda ash manufacturing technology, specifically to a dissolving tank for producing soda ash from waste sodium sulfate. Background Technology

[0002] Based on the study of phase equilibrium laws in complex pentagonal systems, a new short-process technology for the co-production of soda ash and ammonium sulfate from sodium sulfate has been established. The entire process eliminates low-temperature freezing and high-temperature evaporation, and consists of four steps: metathesis reaction, ammonium carbonate recycling, ammonium sulfate crystallization, and room-temperature crystallization. Energy consumption, including electricity and steam, is reduced by approximately 20%. The technology achieves self-circulation of sodium and sulfate ions within the plant, with soda ash purity exceeding 98% and sodium bicarbonate purity exceeding 98.5%; the nitrogen content in ammonium sulfate is greater than 20.5%. This effectively solves the problem of utilizing by-product sodium sulfate and can also be applied to the production of soda ash from mineral sodium sulfate, demonstrating significant economic benefits and broad application prospects, and greatly promoting the development of green chemistry and the circular economy.

[0003] In the existing technology, the dissolving tank used for producing soda ash is prone to uneven mixing when stirring the raw materials inside, which can lead to a decrease in the overall efficiency of soda ash production. In addition, a lot of raw materials tend to adhere to the inner wall of the dissolving tank, which can cause waste. Therefore, it needs to be improved. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a dissolving tank for producing soda ash from waste sodium sulfate, which solves the technical problem that a lot of raw materials tend to adhere to the inner wall of the dissolving tank in the prior art, which easily leads to waste.

[0005] According to one aspect, at least one embodiment of the present invention provides a dissolving tank for producing soda ash from waste sodium sulfate, comprising: a tank body, a discharge pipe extending through and fixedly connected to the bottom of the tank body, a top cover bolted to the top of the tank body, a feed pipe extending through and fixedly connected to the top of the top cover, a motor fixedly installed on the top of the top cover, a fully agitating mechanism disposed inside the tank body, and an impact mechanism disposed on the top of the top cover; the fully agitating mechanism includes a rotating shaft and a hydraulic chamber, the rotating shaft extending through and rotatably connected to the bottom of the top cover, a slider and a rotating gear fixedly connected to the surface of the rotating shaft, a sliding cylinder disposed on the surface of the rotating shaft, a sliding groove formed on the inner side wall of the sliding cylinder, a return spring fixedly connected to the bottom of the sliding cylinder, a stirring blade and a pressure plate fixedly connected to the surface of the sliding cylinder, the hydraulic chamber extending through and fixedly connected to the top of the top cover, a piston rod A slidably connected to one end of the hydraulic chamber, a toothed rod fixedly connected to the end of the piston rod A away from the hydraulic chamber, and a piston rod B slidably connected to the other end of the hydraulic chamber.

[0006] For example, in at least one embodiment of this utility model, a dissolving tank for producing soda ash from waste sodium sulfate is provided, which further includes: the output shaft of the motor is fixedly connected to the rotating shaft, and a brush head is provided at the end of the stirring blade away from the slide. When the motor is turned on, the rotating shaft can be driven to rotate, and when the stirring blade rotates with the slide, the brush head at the other end can clean the inner wall of the tank.

[0007] The slider and the slide groove are provided in two sets, and the two sets of sliders are slidably connected in the two sets of slide grooves respectively. When the rotating shaft rotates, the slide cylinder will rotate synchronously through the cooperation of the two sets of sliders and the two sets of slide grooves.

[0008] The end of the return spring away from the bottom of the slide is fixedly connected to the bottom of the rotating shaft. The elastic force of the return spring is greater than the weight of the slide, and the weight of the slide itself will not cause the return spring to be stretched.

[0009] The rotating gear is an incomplete gear, and the teeth on the rotating gear are initially meshed with the teeth on the rack. When the rotating gear rotates and its teeth mesh with the teeth on the rack, it will drive the rack to move to the right.

[0010] The piston rod B is equipped with a ball bearing at the end away from the hydraulic chamber, and the bottom of the ball bearing is initially in contact with the top of the pressure plate. When the piston rod B moves downward, it will drive the pressure plate to move downward through the ball bearing.

[0011] According to another aspect, at least one embodiment of the present invention also provides an impact mechanism, comprising: a drive gear, a rotating rod, and a pneumatic chamber. The drive gear is fixedly connected to the surface of a rotating shaft, the rotating rod is rotatably connected to the top of a top cover, a driven gear is fixedly connected to the surface of the rotating rod, an eccentric disc is fixedly connected to the top of the rotating rod, the pneumatic chamber is fixedly connected to the top of the top cover, an air bladder is provided at one end of the pneumatic chamber, and an impact rod is slidably connected to a piston inside the other end of the pneumatic chamber.

[0012] For example, in at least one embodiment of this utility model, a dissolving tank for producing soda ash from waste sodium sulfate is provided, which further includes: the driving gear meshes with the driven gear, and the diameter of the driving gear is smaller than that of the driven gear. The rotation of the driving gear will drive the driven gear to rotate, and the speed at which the driven gear rotates one revolution is relatively slow.

[0013] The airbag is initially inflated, and the end of the airbag away from the pressure chamber is close to the eccentric disk. When the eccentric disk rotates with the rotating rod, it will repeatedly squeeze the airbag.

[0014] A rubber block is provided at the end of the impact rod away from the air pressure chamber, and the end of the impact rod away from the air pressure chamber is close to the feed pipe. When the impact rod moves to the left, it will cause the rubber block to hit the feed pipe.

[0015] The beneficial effects of the embodiments of this utility model are as follows:

[0016] This invention incorporates a robust stirring mechanism, allowing the materials produced during soda ash production to be added to the tank. The motor then drives the rotating shaft, which in turn rotates the slide drum via two sets of sliders and two sets of troughs. This rotation of the slide drum, in turn, causes the stirring blades to mix the materials. Simultaneously, a brush head cleans the inner wall of the tank. Furthermore, the coordinated movement of the rotating gears, racks, and hydraulic chamber ensures thorough mixing by repeatedly moving the slide drum up and down.

[0017] This invention incorporates an impact mechanism, which, when the motor is turned on and the rotating shaft is driven by the action gear, driven gear, and air chamber, causes the impact rod to move repeatedly to the right, causing the rubber block to impact the feed pipe. The impact of the rubber block on the feed pipe causes a slight vibration in the feed pipe, preventing the material produced during the soda ash production process from remaining in the tank and being wasted.

[0031] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] like Figures 1-6 The diagram illustrates a dissolving tank for producing soda ash from waste sodium sulfate according to an embodiment of the present invention. The tank includes: a tank body 1; a discharge pipe 2 connected through and fixedly connected to the bottom of the tank body 1; a top cover 3 bolted to the top of the tank body 1; a feed pipe 4 connected through and fixedly connected to the top of the top cover 3; a motor 5 fixedly mounted on the top of the top cover 3; a stirring mechanism 6 disposed inside the tank body 1; and an impact mechanism 7 disposed on the top of the top cover 3. The stirring mechanism 6 includes a rotating shaft 61 and a hydraulic chamber 69. The rotating shaft 61 is rotatably connected to the bottom of the top cover 3, and the surface of the rotating shaft 61 is fixed. A slider 62 and a rotating gear 614 are connected. A slide cylinder 63 is provided on the surface of the rotating shaft 61. A slide groove 64 is provided on the inner side wall of the slide cylinder 63. A return spring 65 is fixedly connected to the bottom of the slide cylinder 63. A stirring blade 66 and a pressure plate 68 are fixedly connected to the surface of the slide cylinder 63. A hydraulic chamber 69 passes through and is fixedly connected to the top of the top cover 3. A piston rod A610 is slidably connected to the piston inside one end of the hydraulic chamber 69. A toothed rod 611 is fixedly connected to the end of the piston rod A610 away from the hydraulic chamber 69. A piston rod B612 is slidably connected to the piston inside the other end of the hydraulic chamber 69.

[0033] In some examples, the output shaft of motor 5 is fixedly connected to the rotating shaft 61, and a brush head 67 is provided at the end of the stirring blade 66 away from the slide 63. When motor 5 is turned on, the rotating shaft 61 can be driven to rotate. When the stirring blade 66 rotates with the slide 63, the brush head 67 at the other end can clean the inner wall of the tank 1.

[0034] Two sets of sliders 62 and two sets of slide grooves 64 are provided, and the two sets of sliders 62 are slidably connected in the two sets of slide grooves 64 respectively. When the rotating shaft 61 rotates, it will drive the slide cylinder 63 to rotate synchronously through the cooperation of the two sets of sliders 62 and the two sets of slide grooves 64.

[0035] The end of the return spring 65 away from the bottom of the inner side of the slide cylinder 63 is fixedly connected to the bottom of the rotating shaft 61. The elastic force of the return spring 65 is greater than the weight of the slide cylinder 63, and the weight of the slide cylinder 63 itself will not cause the return spring 65 to be stretched.

[0036] The rotating gear 614 is an incomplete gear, and the teeth on the rotating gear 614 mesh with the teeth on the rack 611 in the initial state. When the rotating gear 614 rotates and its teeth mesh with the teeth on the rack 611, it will drive the rack 611 to move to the right.

[0037] The piston rod B612 is provided with a ball bearing 613 at the end away from the hydraulic chamber 69. The bottom of the ball bearing 613 is initially in contact with the top of the pressure plate 68. When the piston rod B612 moves downward, it will drive the pressure plate 68 to move downward through the ball bearing 613.

[0038] For example, such as Figures 1-6 As shown, after the materials produced during the soda ash production process are put into tank 1, motor 5 can be turned on to drive shaft 61 to rotate. The rotation of shaft 61 will drive slide cylinder 63 to rotate through the cooperation of two sets of sliders 62 and two sets of slide grooves 64. The rotation of slide cylinder 63 will drive stirring blades 66 to stir and mix the materials. At the same time, brush head 67 will clean the inner wall of tank 1. The rotation of shaft 61 will also drive rotating gear 614 to rotate. When rotating gear 614 rotates and its upper teeth mesh with the upper teeth of gear 611, it will drive gear 611 to move to the right. The rightward movement of gear 611 will drive piston rod A610 to move to the right. The rightward movement of piston rod A610 will drive hydraulic chamber The hydraulic pressure inside the hydraulic chamber 69 drives the piston rod B612 to move downward. When the piston rod B612 moves downward, it drives the pressure plate 68 to move downward through the ball bearing 613. The downward movement of the pressure plate 68 drives the slide cylinder 63 to move downward, and the return spring 65 is stretched. When the rotating gear 614 rotates to the toothless part and disengages from the toothed rod 611, the return spring 65 rebounds and drives the slide cylinder 63, pressure plate 68 and piston rod B612 to move upward to restore their original positions. The hydraulic pressure inside the hydraulic chamber 69 drives the piston rod A610 and the toothed rod 611 to move to the left to restore their original positions, thus forming a cycle. The slide cylinder 63 moves up and down repeatedly during rotation to ensure complete mixing and improve the efficiency of soda ash production.

[0039] like Figures 1-6 As shown, the impact mechanism 7 in another embodiment of the present invention includes: a drive gear 71, a rotating rod 72, and a pressure chamber 75. The drive gear 71 is fixedly connected to the surface of the rotating shaft 61. The rotating rod 72 is rotatably connected to the top of the top cover 3. A driven gear 73 is fixedly connected to the surface of the rotating rod 72. An eccentric disk 74 is fixedly connected to the top of the rotating rod 72. The pressure chamber 75 is fixedly connected to the top of the top cover 3. An air bladder 76 is provided at one end of the pressure chamber 75. An impact rod 77 is slidably connected to the piston inside the other end of the pressure chamber 75.

[0040] In some examples, the driving gear 71 meshes with the driven gear 73, and the diameter of the driving gear 71 is smaller than that of the driven gear 73. The rotation of the driving gear 71 will drive the driven gear 73 to rotate, and the driven gear 73 rotates at a slower speed.

[0041] In its initial state, the airbag 76 is inflated, and the end of the airbag 76 away from the air chamber 75 is close to the eccentric disk 74. When the eccentric disk 74 rotates with the rotating rod 72, it will repeatedly squeeze the airbag 76.

[0042] A rubber block is provided at the end of the impact rod 77 away from the air pressure chamber 75, and the end of the impact rod 77 away from the air pressure chamber 75 is close to the feed pipe 4. When the impact rod 77 moves to the left, it will cause the rubber block to impact the feed pipe 4.

[0043] For example, such as Figures 1-6 As shown, when the rotating shaft 61 rotates, it also drives the driving gear 71 to rotate. The rotation of the driving gear 71 drives the driven gear 73 to rotate. The driven gear 73 rotates at a slower speed. The rotation of the driven gear 73 drives the rotating rod 72 to rotate. The rotation of the rotating rod 72 drives the eccentric disk 74 to rotate and repeatedly squeeze the air bag 76. When the air bag 76 is squeezed, the air pressure inside it enters the air pressure chamber 75 and pushes the impact rod 77 to move to the left. The leftward movement of the impact rod 77 causes the rubber block to hit the feed pipe 4. When the air bag 76 rebounds, the air pressure drives the impact rod 77 to move to the right to return to its original position. The impact of the rubber block on the feed pipe 4 causes the feed pipe 4 to vibrate slightly, preventing the material produced during the production of soda ash from remaining in the tank 1 and being wasted.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
