Description

Technical Field

[0001] This utility model relates to the field of celestite roasting fume filtration technology, and in particular to a celestite roasting fume filtration device. Background Technology

[0002] Celestite is mainly used in the manufacture of strontium carbonate and in the production of television picture tube glass. Its colors include blue, green, yellowish-green, orange, and light blue-gray, and sometimes it is colorless and transparent. Roasting is a process that completes a chemical reaction below the material's melting temperature, serving as part of the furnace charge preparation. Most of the material remains in a solid state, therefore the roasting temperature is limited to ensure that the material does not significantly melt. Clearly, the roasting reaction is primarily a solid-gas reaction, sometimes involving solid-solid, solid-liquid, and gas-liquid interactions. Roasting mostly prepares for subsequent major smelting operations such as smelting or leaching, and is therefore often a furnace charge preparation step in the smelting process. However, it can also sometimes be used as an enrichment, impurity removal, metal powder preparation, or refining process.

[0003] The roasting process of celestite generates a large amount of dust and heat, which, if released directly into the air, will pollute the environment. At the same time, common dust filtration devices, after prolonged use, are prone to clogging the mesh due to dust accumulation, affecting the filtration process. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a celestite roasting fume filtration device, which aims to improve the fume filtration device, which is prone to clogging the mesh due to the accumulation of fume after long-term use, thus affecting the filtration process.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a celestite roasting fume filtration device, comprising a water tank with an inlet and an outlet, a support frame fixed to the top of the water tank, a filter box slidably disposed between the support frames, a plurality of filter screens being slidably installed inside the filter box, telescopic pipes fixed to the top and bottom of the filter box, an air inlet pipe fixed to the end of the upper telescopic pipe and fixed to the support frame, and the bottom end of the lower telescopic pipe penetrating the water tank and extending into the water tank, the water tank being provided with a vertical movement mechanism for driving the filter box to move up and down for vibration sieving, and an exhaust pipe for use in conjunction with the air inlet pipe being installed on the water tank.

[0006] Preferably, the up-and-down movement mechanism includes a rotating shaft rotatably mounted on the water tank, a motor fixed to the upper surface of the water tank, the rotating shaft being fixedly connected to the output shaft of the motor, and a plurality of push plates being eccentrically fixed to the outer surface of the rotating shaft, the outer surface of the push plates being in contact with the surface of the filter box.

[0007] Preferably, the filter box is provided with mounting brackets on both sides and guide rods are fixed inside the mounting brackets. Movable blocks are fixed on both sides of the filter box. The movable blocks are slidably disposed on the outer surface of the guide rods. A slider is fixed on the side of the mounting bracket and is slidably disposed inside the support frame.

[0008] Preferably, a spring is fixed to the upper surface of the slider, and the other end of the spring is fixedly installed on the inner wall of the support frame.

[0009] Preferably, wedge-shaped blocks are fixed on both sides of the filter box, and wedge-shaped blocks are installed on the support frame to slide against wedge-shaped blocks. A T-shaped block is fixed at the position where wedge-shaped blocks 2 and wedge-shaped blocks 1 are attached. The T-shaped block is slidably disposed in the T-shaped groove opened on wedge-shaped blocks 1.

[0010] Preferably, a spray plate is fixed inside the filter box, a water pump is fixed to the side of the water tank, the inlet pipe of the water pump passes through the water tank and extends below the liquid surface inside the water tank, and the outlet pipe of the water tank is fixedly connected to the inlet of the spray plate.

[0011] Preferably, a second filter screen is slidably installed inside the water tank, and the second filter screen is located above the water pump outlet pipe.

[0012] Preferably, the water tank has multiple partitions fixed inside, and the multiple partitions form an S-shaped gas flow space.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, by setting up a filter box, a filter screen, and an up-and-down movement mechanism, the up-and-down movement mechanism can drive the filter box to move multiple filter screens up and down synchronously. The movement of the filter screen can achieve the effect of vibration sieving, while avoiding dust clogging the mesh and ensuring the filtration effect.

[0015] 2. In this utility model, by setting wedge block one, wedge block two, and T-block, the filter box moves up and down while driving wedge block one to move synchronously. While wedge block one moves up and down, it comes into contact with wedge block two, which drives wedge block one to move back and forth. The movement of wedge block one drives the filter box to move synchronously, realizing the back and forth vibration operation of the filter box. At the same time, the T-block can limit and guide wedge block one, ensuring that wedge block one and wedge block two are always in contact, avoiding the problem of the filter box getting stuck and causing wedge block one and wedge block two to separate.

[0016] 3. In this utility model, by setting a second filter screen, the gas enters the water tank for secondary filtration and cooling. The second filter screen can filter the liquid inside the water tank and pump it into the spray plate for use, realizing secondary utilization and reducing resource waste.

[0025] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] Reference Figures 1-3This utility model provides an embodiment of a celestite roasting fume filtration device, comprising a water tank 1 with an inlet and an outlet, a support frame 2 fixed to the top of the water tank 1, a filter box 3 slidably mounted between the support frames 2, a plurality of filter screens 4 sealed and slidably installed inside the filter box 3, telescopic pipes 5 fixed to the top and bottom of the filter box 3, an air inlet pipe 6 fixed to the end of the upper telescopic pipe 5 and fixed to the support frame 2, and the bottom end of the lower telescopic pipe 5 penetrating the water tank 1 and extending into the water tank 1, and the water tank 1 being provided with a mechanism for driving the filter box 3 to move up and down. The system includes a vibrating sieve with an up-and-down motion mechanism. The water tank 1 is equipped with an exhaust pipe 17 that works in conjunction with the air inlet pipe 6. By setting up a filter box 3, filter screens 4, and an up-and-down motion mechanism, the filter box 3 can drive multiple filter screens 4 to move up and down synchronously. The movement of the filter screens 4 can achieve the effect of vibrating sieve while preventing dust from clogging the mesh and ensuring the filtration effect. By setting up a telescopic pipe 5, the system can make adaptive adjustments while the filter box 3 moves up and down, ensuring stable gas delivery and improving the stability of the operation.

[0027] Reference Figure 5 The up-and-down movement mechanism includes a rotating shaft 15 rotatably mounted on the water tank 1. A motor 14 is fixed on the upper surface of the water tank 1. The rotating shaft 15 is fixedly connected to the output shaft of the motor 14. Multiple push plates 16 are eccentrically fixed on the outer surface of the rotating shaft 15. The outer surface of the push plates 16 is in contact with the surface of the filter box 3. By setting up the motor 14, the rotating shaft 15 and the push plates 16, the motor 14 drives the rotating shaft 15 to rotate. The rotation of the rotating shaft 15 drives the push plates 16 to rotate eccentrically. In this way, the push plates 16 can push the filter box 3 to move up and down, so that the filter box 3 drives the filter screen 4 to move up and down reciprocally for filtration, thereby improving the filtration effect.

[0028] Reference Figure 4 and Figure 5 The filter box 3 is equipped with mounting brackets 9 on both sides, and guide rods 8 are fixed inside the mounting brackets 9. Movable blocks 7 are fixed on both sides of the filter box 3. The movable blocks 7 are slidably disposed on the outer surface of the guide rods 8. A slider 10 is fixed on the side of the mounting bracket 9. The slider 10 is slidably disposed inside the support frame 2. By setting the movable blocks 7, guide rods 8, mounting brackets 9 and sliders 10, the movable blocks 7 and sliders 10 play a limiting and guiding role for the filter box 3. The slider 10 slides inside the support frame 2. The mounting brackets 9, guide rods 8 and movable blocks 7 drive the filter box 3 to move up and down, ensuring the stability of the up and down movement of the filter box 3. The sliding of the movable blocks 7 on the outer surface of the guide rods 8 can drive the filter box 3 to move back and forth, so that the filter box 3 can achieve both up and down vibration filtration and back and forth vibration filtration, further improving the filtration effect.

[0029] Reference Figure 4A spring 22 is fixed on the upper surface of the slider 10, and the other end of the spring 22 is fixedly installed on the inner wall of the support frame 2. By setting the spring 22, the slider 10 is driven downward by the elasticity of the spring 22, so that the filter box 3 can move downward stably and fit with the push plate 16, avoiding the problem of the filter box 3 getting stuck and ensuring the stable operation of the vibration filtration.

[0030] Reference Figure 2 and Figure 6 Both sides of the filter box 3 are fixed with wedge blocks 18. A second wedge block 20 is installed on the support frame 2, sliding and conforming to the first wedge block 18. A T-shaped block 19 is fixed at the position where the second wedge block 20 conforms to the first wedge block 18. The T-shaped block 19 is slidably disposed within a T-shaped groove opened on the first wedge block 18. By setting the first wedge block 18, the second wedge block 20, and the T-shaped block 19, the filter box 3 moves up and down while simultaneously driving the first wedge block 18 to move synchronously. While moving up and down, wedge 18 engages with wedge 20, causing wedge 18 to move back and forth. The movement of wedge 18 simultaneously drives the filter box 3 to move synchronously, achieving the back-and-forth vibration of the filter box 3. At the same time, T-block 19 can limit and guide wedge 18, ensuring that wedge 18 and wedge 20 are always in contact, avoiding the problem of filter box 3 jamming and causing wedge 18 and wedge 20 to detach.

[0031] Reference Figure 5 A spray plate 21 is fixed inside the filter box 3, and a water pump 13 is fixed on the side of the water tank 1. The inlet pipe of the water pump 13 passes through the water tank 1 and extends below the liquid level inside the water tank 1. The outlet pipe of the water tank 1 is fixedly connected to the inlet of the spray plate 21. By setting up the water pump 13 and the spray plate 21, the water pump 13 draws water and sends it into the spray plate 21 for spraying, which can quickly reduce dust in the gas inside the filter box 3. The water flow adsorbs and carries away the dust inside the gas, improving the filtration effect.

[0032] Reference Figure 3 A filter screen 12 is installed in a sealed sliding manner inside the water tank 1. The filter screen 12 is located above the water outlet pipe of the water pump 13. By setting the filter screen 12, the gas enters the water tank 1 for secondary filtration and cooling. The filter screen 12 can filter the liquid inside the water tank 1 and pump it into the spray plate 21 for use by the water pump 13, so as to realize secondary utilization and reduce resource waste.

[0033] Reference Figure 3 The water tank 1 has multiple partition plates 11 fixed inside, which form an S-shaped gas flow space. By setting the partition plates 11, the incoming flue gas can be guided so that the flue gas can fully contact the liquid inside the water tank 1, thereby improving the treatment effect of flue gas.

[0034] Working principle: The motor 14 and water pump 13 are turned on. The gas enters the filter box 3 through the air inlet pipe 6 and the telescopic pipe 5. The gas is initially filtered by the filter screen 4. The water pump 13 pumps water into the spray plate 21 and sprays it out. The water flow adsorbs and carries away the dust inside the gas, and performs rapid dust reduction on the gas inside the filter box 3.

[0035] At the same time, the motor 14 drives the rotating shaft 15 to rotate, and the rotating shaft 15 drives the push plate 16 to rotate eccentrically. In turn, the push plate 16 can push the filter box 3 to move up and down, so that the filter box 3 drives the filter screen 4 to move up and down repeatedly for filtration. While the filter box 3 moves up and down, it drives the wedge block 18 to move synchronously. While the wedge block 18 moves up and down, it comes into contact with the wedge block 20, which will drive the wedge block 18 to move back and forth. While the wedge block 18 moves, it drives the filter box 3 to move synchronously, so as to realize the back and forth vibration operation of the filter box 3.

[0036] After the gas is initially filtered by the filter box 3, it enters the water tank 1. The gas undergoes a second filtration process with the water inside the water tank 1, and then the gas is discharged from the exhaust pipe 17 through the partition plate 11.

[0037] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
