Description

Technical Field

[0001] This invention relates to the field of glass production technology, specifically to a waste gas denitrification product recovery device for glass production. Background Technology

[0002] Glass is an amorphous inorganic non-metallic material, generally made from a variety of inorganic minerals (such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash, etc.) as the main raw materials, with the addition of a small amount of auxiliary raw materials.

[0003] The waste gas generated during glass production, after being treated by a denitrification catalyst, leaves behind waste denitrification catalyst containing valuable metals. Direct emission of this catalyst results in resource waste. According to patent application number CN201720214788.5, a method can be used to clean the waste catalyst powder and waste metal powder from the SCR waste denitrification catalyst plate, enabling the reuse of these materials and turning waste into treasure. The top cover design prevents the recycled cleaning liquid from splashing out, ensuring a high safety factor for this invention. The design also includes a stirring paddle, elongated holes, and a slider. The combination of slide rails and agitator causes the cleaning fluid in the recovery tank to rotate. When the basket moves left and right on the slide rails, it drives the cleaning fluid to move left and right. The two types of cleaning fluids collide violently with the SCR spent denitrification catalyst plates in the basket, which can quickly clean or knock off the spent catalyst powder and spent metal powder on the SCR spent denitrification catalyst plates, making the SCR spent denitrification catalyst plates thoroughly cleaned. The solid-liquid separation device realizes the automatic separation of spent catalyst powder and spent metal powder.

[0004] In the aforementioned patent, the spent denitrification catalyst is placed in a basket and immersed in the recycling tank for cleaning. However, some of the spent denitrification catalyst floats in the cleaning solution, making it difficult to penetrate the solution. Static placement also results in low dispersion efficiency of the spent denitrification catalyst, making it difficult to achieve rapid separation between catalyst powder and metal particles. Furthermore, manual disassembly and reassembly of the filter screen is required for subsequent collection of metal particles, which is very inconvenient. This invention fails to achieve automatic collection of metal particles and increases labor costs. Therefore, to address the above shortcomings, the present invention makes the following improvements. Summary of the Invention

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Example 1

[0026] Please see Figures 1 to 3 As shown, the present invention provides a technical solution, with specific improvements as follows:

[0027] A device for recovering denitrification products from waste gas used in glass production includes a recovery box 1, with an installation frame 2 fixedly installed inside the recovery box 1. A filter plate 3 is rotatably mounted between the two sides of the inner wall of the installation frame 2. A drive motor is installed inside the installation frame 2, which controls the filter plate 3 to rotate. A fixing plate 4 is fixedly mounted between the two sides of the inner wall of the installation frame 2 and on its top surface. A discharge pipe 10 is connected inside the fixing plate 4. A conduit 11 is connected to the bottom surface of the recovery box 1. Both the conduit 11 and the discharge pipe 10 are equipped with solenoid valves, which are controlled by different switches. A placement frame 5 is installed inside the recovery box 1 and above the fixing plate 4. The surface of the placement frame 5 has several through holes. An L-shaped plate 6 is installed on the top surface of the recovery box 1, and a downward crushing mechanism 7 is installed on the surface of the L-shaped plate 6. The downward crushing mechanism 7 includes a pressure plate 71 and a rotating ring 72 rotatably mounted inside the pressure plate 71. A first motor 77 is fixedly mounted on the top surface of the L-shaped plate 6, and a rotating rod 78 is fixedly mounted on the output end of the first motor 77 via a coupling. The bottom end of the rotating rod 78 passes through a rotating ring 72 and is rotatably connected to the bottom of the inner wall of the placement frame 5. A sliding groove is formed on the surface of the rotating rod 78, and a protrusion adapted to the sliding groove is provided inside the rotating ring 72. The protrusion is slidably disposed inside the sliding groove. Several crushing rollers 73 are fixedly mounted on the bottom of the rotating ring 72. Electric push rods 74 are fixedly installed on both sides inside, and the extended end of the electric push rods 74 is fixedly connected to the top surface of the pressure plate 71. Booster water pumps 75 are fixedly installed on the top of both sides of the recycling box 1, and the water inlet of the booster water pump 75 is connected to the surface of the recycling box 1 through a connecting pipe. The water outlet of the booster water pump 75 is connected to the top surface of the pressure plate 71 through a water outlet pipe 76, and the surface of the water outlet pipe 76 is provided with a telescopic section, which allows the water outlet pipe 76 to extend and retract.

[0028] The waste denitrification catalyst plate is placed inside the placement frame 5, and a certain amount of cleaning water is injected into the recycling box 1. Then, the electric push rod 74 is activated, so that the extended end of the electric push rod 74 drives the pressure plate 71 to move downward. At this time, the pressure plate 71 drives the rotating ring 72 to move downward synchronously along the surface of the rotating rod 78. The pressure plate 71 continues to descend, and with the setting of the crushing roller 73, the waste denitrification catalyst plate can be pushed downward synchronously until the waste denitrification catalyst plate contacts the bottom of the inner wall of the placement frame 5. At this time, the waste denitrification catalyst plate can be located inside the cleaning water, so that it can make full contact and will not float on the water surface. Then, the first motor 77 is activated, so that the first motor 77 drives the rotating rod 78 to rotate. The rotating ring 72 can rotate synchronously with the setting of the protrusion and the sliding groove. During the rotation of the rotating ring 72, the crushing roller 73 can rotate synchronously. The setting of the crushing roller 73 can crush the waste denitrification catalyst plate, realize its rapid dispersion, and accelerate the dissolution speed with water.

[0029] At the same time, the booster water pump 75 is started, so that the booster water pump 75 draws water from the inside of the recovery tank 1 through the connecting pipe, and then transports the water to the inside of the placement frame 5 through the water outlet pipe 76. This cycle keeps the water flowing and the water flow with a certain pressure can rinse the waste denitrification catalyst plate, further accelerating the dissolution rate of the waste denitrification catalyst plate.

[0030] Once the waste denitrification catalyst plate is completely dissolved, the solenoid valves inside the discharge pipe 10 and conduit 11 are opened, allowing the liquid to fall through the discharge pipe 10 to the top surface of the filter plate 3. The dissolved waste catalyst powder is discharged through the conduit 11 for subsequent processing, while the undissolved waste metal particles are trapped on the top surface of the filter plate 3, waiting to be collected later.

[0031] Example 2

[0032] Based on Example 1, please refer to Figure 1 , Figure 2 as well as Figure 4 As shown, the specific improvements are as follows:

[0033] The recycling bin 1 is equipped with a cleaning component 8, which includes U-shaped plates 81 on both sides of the top surface of the mounting frame 2. A cleaning brush 84 is fixedly mounted on the inner wall of the U-shaped plate 81 by a buffer spring 82. Electric slide rails 83 are fixedly mounted on both sides of the recycling bin 1, and a U-shaped rod 85 is slidably mounted on the bottom surface of the electric slide rails 83 by a sliding block. A second motor 86 is fixedly mounted on one end of the U-shaped rod 85, and a connecting rod 87 is fixedly mounted on the output end of the second motor 86 by a coupling. A gear 88 is fixedly mounted on one end of the connecting rod 87 inside the recycling bin 1. A toothed plate 89 that meshes with the gear 88 is fixedly mounted on the front side of the U-shaped plate 81. The other end of the U-shaped rod 85 is slidably connected to one side of the U-shaped plate 81 by a T-shaped slider.

[0034] The drive motor is started, causing it to rotate the filter plate 3 90 degrees until it is fully rotated. Figure 2In the state shown, the filter plate 3 is vertically positioned inside the mounting frame 2. Then, the electric slide rail 83 is activated, causing it to move the U-shaped rod 85 into the recycling bin 1. The U-shaped plate 81 moves synchronously. The cleaning brush 84, under the action of the buffer spring 82, contacts the surface of the filter plate 3. The second motor 86 is then activated, causing it to drive the gear 88 to rotate via the connecting rod 87. During rotation, the gear 88 drives the U-shaped plate 81 downwards via the toothed plate 89, thus completely removing the metal particles trapped on the surface of the filter plate 3. This facilitates subsequent unified collection and avoids resource waste caused by metal particle residue. After cleaning, the U-shaped plate 81 is moved back to its initial position, and then the filter plate 3 is rotated back to its initial position, ready for subsequent use.

[0035] Example 3

[0036] Based on Example 2, please refer to Figure 1 , Figure 2 as well as Figure 4 As shown, the specific improvements are as follows:

[0037] The recycling bin 1 is provided with collection components 9 on both sides, and the collection components 9 include U-shaped frames 91 that are slidably disposed on both sides of the recycling bin 1. Both sides of the recycling bin 1 are provided with through grooves that are adapted to the U-shaped frames 91, and a sealing ring is provided inside the through grooves. A collection box 92 is slidably disposed inside the U-shaped frame 91. Both sides of the bottom surface of the recycling bin 1 are provided with control parts for driving the U-shaped frames 91 to slide through support frames. The control parts include hydraulic cylinders 93 that are rotatably disposed on the surface of the support frames, and the extended end of the hydraulic cylinders 93 is rotatably connected to one side of the bottom surface of the U-shaped frame 91 through a connecting shaft.

[0038] Activate hydraulic cylinder 93 to retract its extended end. During the retraction process, the U-shaped frame 91 is pushed into the recycling box 1 until the two U-shaped frames 91 are relatively close. At this time, the collection box 92 is located inside the recycling box 1, and the removed metal particles can be collected. Similarly, by controlling the extended end of hydraulic cylinder 93 to extend, the collection box 92 can be slid out of the recycling box 1 through the U-shaped frame 91, making it convenient for personnel to remove the collection box 92.

[0039] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0040] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
