Abstract
Description
Technical Field
[0001] This utility model relates to the field of double-chamber lime kiln technology, and in particular to a novel constant calorific value double-chamber lime kiln. Background Technology
[0002] A double-chamber lime kiln is a device used to produce lime. It typically consists of two consecutive chambers, each with an inlet and an outlet. During production, limestone is placed in the first chamber and heated to a high temperature, which causes the limestone to undergo a chemical reaction to produce quicklime. The quicklime is then cooled in the second chamber and transformed into hydrated lime.
[0003] A search revealed a public disclosure (announcement) number: CN222226208U, which discloses a constant calorific value double-chamber lime kiln, comprising: a support base, a double-chamber lime kiln body, a feed pipe, and a heat exchange coil. A pump body and a filter box are mounted on the top surface of the support base. The double-chamber lime kiln body is mounted on the top surface of the support base via a mounting bracket, and a connecting pipe is provided on the double-chamber lime kiln body. The feed pipe is located on the top surface of the double-chamber lime kiln body, and a discharge pipe is located on the bottom surface of the double-chamber lime kiln body. A hopper is embedded and fixed on the top surface of the feed pipe. A combustion-supporting pipe is embedded and fixed on the side surface of the double-chamber lime kiln body. A heat exchange coil is fitted onto the discharge pipe. A connecting pipe is embedded and fixed on the heat exchange coil. An exhaust pipe and an air inlet pipe are provided on the pump body. This utility model meets the requirements for use in double-chamber lime kilns, avoiding direct heat exchange inside the kiln during combustion support.
[0004] In the aforementioned existing technical solutions, the filter element is installed flush against the inner wall of the air filter box. Over time, pollutants accumulate on the filter element, and the filtration effect gradually decreases, requiring regular cleaning. During the cleaning process, the filter element needs to be disassembled for manual or mechanical cleaning, which is cumbersome, time-consuming, and labor-intensive, affecting production efficiency and increasing equipment maintenance costs.
[0005] Therefore, we propose a novel constant calorific value double-chamber lime kiln. Utility Model Content
[0006] The present invention aims to solve the technical problems existing in the prior art and provide a novel constant calorific value double-chamber lime kiln.
[0007] To achieve the above objectives, this utility model adopts the following technical solution: a novel constant calorific value double-chamber lime kiln, comprising a base, a double-chamber lime kiln body, a filter box, and a pump body. The base has inclined grooves on both sides of its inner cavity, within which a filter screen slides. A slot is formed on the rear side wall of the filter box. A collection box is fixed to the outside of the filter box, containing a dust collection box. A rotating shaft is installed inside the filter box, and a water wheel is fitted onto the rotating shaft. Mounting frames are fixed to the side walls of the water wheel, and each mounting frame has a limit groove. Limit blocks slide within the limit grooves, and connecting plates are fixed to the limit blocks. Cleaning brushes and return springs are fixed to both sides of the connecting plate, respectively.
[0008] Preferably, the top and side walls of the filter box are connected to an air inlet pipe one and an air inlet pipe two, respectively, and the air outlet of the pump body is connected to an exhaust pipe.
[0009] Preferably, the second air inlet pipe is connected to the wall of the filter box near the pump body, the outlet end of the second air inlet pipe is connected to the inlet end of the pump body, and both ends of the exhaust pipe are connected to the body of the double-chamber lime kiln.
[0010] Preferably, the cleaning brush is fixed to the wall surfaces of the connecting plates that are far apart from each other, and the return spring is fixed to the wall surface of the inner cavity of the mounting frame.
[0011] Preferably, the cleaning brush works in conjunction with the filter screen, and the other end of the return spring is fixedly connected to the wall of the connecting plate.
[0012] Preferably, the mounting frame has a U-shaped structure.
[0013] This utility model provides a novel constant calorific value double-chamber lime kiln. It has the following beneficial effects:
[0014] 1. This new type of constant calorific value double-chamber lime kiln, through the cooperation of water wheel, mounting frame, reset spring, connecting plate and cleaning brush, facilitates the cleaning of filter screen pores. Dust enters the collection box through the slot and is collected by the dust collection box, thus eliminating the need for frequent disassembly, improving production efficiency and reducing equipment maintenance costs.
[0015] 2. This new type of constant calorific value double-chamber lime kiln, through the inclined filter screen, can increase the contact time and contact area between the flue gas and the filter screen, which helps to effectively filter particulate matter in the flue gas, reduce pollutant emissions, improve flue gas purification efficiency, and meet environmental protection standards.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Example: A novel constant calorific value double-chamber lime kiln, such as Figures 1-4As shown, the system includes a base 1, on which two double-chamber lime kiln bodies 101 are mounted. A filter box 2 and a pump body 3 are installed on the top surface of the base 1. An air inlet pipe 201 is connected to the top of the filter box 2, and an air inlet pipe 301 is connected to the wall of the filter box 2 near the pump body 3. The outlet end of the air inlet pipe 301 is connected to the air inlet end of the pump body 3. An exhaust pipe 302 is connected to the outlet end of the pump body 3, and both ends of the exhaust pipe 302 are connected to the double-chamber lime kiln bodies 101. Sliding grooves 501 are inclinedly opened on both sides of the inner cavity of the base 1. A filter screen 5 is slidably connected to the inner cavity of the sliding groove 501. A slot 402 is opened on the rear wall of the filter box 2 at a position corresponding to the lower end of the filter screen 5. A fixed connection is made on the outer wall of the filter box 2 at a position adapted to the slot 402. The collection box 4 has a dust collection box 401 inside. The filter box 2 has a rotating shaft 6 installed inside and above the filter screen 5. A water wheel 601 is fitted on the rotating shaft 6. U-shaped mounting frames 7 are fixedly connected to the walls of the water wheels 601 that are far apart from each other. Limiting grooves 701 are opened on the walls of the mounting frames 7 that are far apart from each other. Limiting blocks 702 are slidably connected to the inner cavities of the limiting grooves 701. Connecting plates 703 are fixedly connected to the walls opposite to the limiting blocks 702. Multiple cleaning brushes 704 are fixedly connected to the walls of the connecting plates 703 that are far apart from each other. The cleaning brushes 704 cooperate with the filter screen 5. Multiple return springs 705 are fixedly connected to the walls of the inner cavities of the mounting frames 7. The other end of the return springs 705 is fixedly connected to the wall of the connecting plates 703.
[0026] The working principle of this utility model:
[0027] When in use, when the flue gas enters from the inlet pipe 201, it will drive the water wheel 601 to rotate, which in turn drives the mounting frame 7 to rotate. At this time, with the cooperation of the return spring 705 and the connecting plate 703, the cleaning brush 704 cleans the filter holes of the filter screen 5. The dust on the filter screen 5 enters the inner cavity of the collection box 4 through the slot 402 of the inclined filter screen 5 and is collected by the dust collection box 401 for unified treatment of the dust.
