Description

Technical Field

[0001] This utility model relates to the field of calcium oxide production and processing technology, specifically a calcining furnace for calcium oxide production. Background Technology

[0002] Calcium oxide calcining furnaces are a dynamic calcination process used to produce calcium oxide from calcium carbonate. Calcium carbonate decomposes at high temperatures to form calcium oxide. Due to its rapid calcination and uniform heat transfer, it is an advanced process for producing active calcium oxide and is also used to decompose causticized lime. However, existing calcium oxide calcining furnaces often fail to thoroughly pulverize the calcium carbonate, resulting in numerous lumps and incomplete reaction during calcination, thus wasting material.

[0003] A search revealed Chinese patent application number 202320787122.4, which discloses a calcining furnace for calcium oxide production, comprising a furnace body and a crushing box. The crushing box contains a crushing mechanism, including two crushing rollers and two cutting rollers. The two crushing rollers are located at the top of the crushing box, and the two cutting rollers are located at the bottom. A conveying auger is installed at the bottom of the crushing box, and a conveying pipe is installed on one side of the bottom of the auger, communicating with the interior of the furnace body. This device, through the cooperation of the crushing and cutting rollers of the crushing mechanism, can more thoroughly crush the calcium oxide entering the furnace body for calcination, and avoids the situation where the crushing effect is poor due to a small amount of calcium oxide injected. It effectively solves the problem that a single crushing blade can only crush calcium oxide entering the furnace for calcination, but the crushing effect is generally poor.

[0004] However, the aforementioned calcining furnace for calcium oxide production still has the following drawbacks:

[0005] The pulverizing device may fail to pulverize larger particles during the pulverizing process. These larger particles cannot be fully decomposed during calcination, which leads to a decline in product quality. Therefore, we need a calcining furnace for calcium oxide production to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a calcining furnace for calcium oxide production. It mainly uses a crushing component to directly and effectively crush the raw materials entering the calcining furnace. The limiting groove and pluggable screen design facilitate the installation and replacement of screens with different mesh sizes to meet the needs of different particle sizes. Through the filtering effect of the screen, large particles that have not been completely crushed can be further screened out. The inclined design promotes the natural sliding of the crushed material into the collection box, which provides convenience for subsequent calcination operations.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a calcining furnace for calcium oxide production, comprising a calcining furnace body, a crushing box installed at the upper end of the calcining furnace body, a crushing component installed at the inner top of the crushing box, an installation frame installed below the crushing component, a limiting groove formed in the inner wall of the installation frame, a screen installed inside the limiting groove, the side wall of the screen being inserted into the inside of the limiting groove, the installation frame and the screen being inclined, a through groove formed on the lower end face of the inclined end of the installation frame, a collecting box provided on one side of the through groove, a collecting trough provided inside the collecting box, and a limiting component connecting the side wall of the collecting box to the side wall of the crushing box.

[0008] Preferably, the top of the crushing box is provided with a feeding trough, which is open.

[0023] Please see Figure 1-5This utility model provides a technical solution: a calcining furnace for calcium oxide production, including a calcining furnace body 1, a crushing box 3 installed at the upper end of the calcining furnace body 1, a crushing component installed at the inner top of the crushing box 3, an installation frame 6 installed below the crushing component, a limiting groove 602 opened in the inner wall of the installation frame 6, a screen 601 installed inside the limiting groove 602, the side wall of the screen 601 being inserted into the inside of the limiting groove 602, the installation frame 6 and the screen 601 being inclined, a through groove 603 opened at the lower end face of the inclined end of the installation frame 6, a collection box 7 provided on one side of the through groove 603, a collection groove 703 provided inside the collection box 7, and a limiting component connecting the side wall of the collection box 7 and the side wall of the crushing box 3;

[0024] In use, by installing a crushing box 3 on the upper end of the calcining furnace body 1 and arranging a crushing component at the top of the box, the raw materials entering the calcining furnace can be directly and effectively crushed. The limiting groove 602 and the pluggable screen 601 designed in the mounting frame 6 not only facilitate the installation and replacement of screens 601 with different mesh sizes to meet different particle size requirements, but also further screen out large particles that have not been completely crushed through the filtering effect of the screen 601. The inclined design promotes the natural sliding of the crushed material, while the through groove 603 ensures that the material that meets the particle size requirements can smoothly enter the collection box 7. The collection groove 703 in the collection box 7 is designed to facilitate the centralized storage and processing of crushed and screened qualified materials, providing convenience for subsequent calcination operations.

[0025] The top of the crushing box 3 is provided with a feeding trough 4, which is open. The open feeding trough 4 makes it easy for operators to quickly and accurately feed raw materials, reducing the time consumption and errors in the raw material feeding process.

[0026] The crushing assembly includes two crushing motors 5, a crushing roller 501, and multiple crushing blades 502. The base of the crushing motor 5 is mounted on the outer wall of the crushing chamber 3. The output shaft of the crushing motor 5 passes through the side wall of the crushing chamber 3 and is connected to one end of the crushing roller 501. The other end of the crushing roller 501 is rotatably mounted on the other side inner wall of the crushing chamber 3. Multiple crushing blades 502 are equidistantly mounted on the surface of the crushing roller 501. The two crushing motors 5 rotate relative to each other, which can drive the two crushing rollers 501 to rotate in opposite directions, thereby crushing the raw materials entering the crushing chamber 3 more effectively.

[0027] The limiting component includes a protrusion 701 and a groove 702. The protrusion 701 is installed on the side wall of the crushing box 3, and the groove 702 is opened at the bottom of the collection box 7. The protrusion 701 is inserted into the inside of the groove 702. The insertion design of the protrusion 701 and the groove 702 forms a physical constraint, which effectively enhances the connection stability between the crushing box 3 and the collection box 7.

[0028] A feeding trough is provided on one side of the bottom of the crushing box 3, and a guide pipe 802 is installed on one side of the feeding trough. One end of the guide pipe 802 is connected to a feeding component. The setting of the feeding trough and the guide pipe 802 ensures that the crushed material can be smoothly discharged from the crushing box 3, avoiding the retention and blockage of material in the crushing box 3.

[0029] The feeding assembly includes a feeding motor 801, a feeding auger 8, and a conveying pipe 803. The output shaft of the feeding motor 801 is connected to one end of the feeding auger 8, and one side of the bottom end of the feeding auger 8 is connected to one end of the conveying pipe 803. The other end of the conveying pipe 803 is connected to the interior of the calcining furnace body 1. The feeding motor 801 serves as a power source, which can stably and continuously drive the feeding auger 8 to rotate. The feeding auger 8 conveys the material from one end to the other through the pushing action of its spiral blades, realizing continuous and efficient material conveying. Compared with manual feeding or intermittent feeding equipment, this feeding method improves production efficiency.

[0030] The bottom of the crushing box 3 is equipped with support columns 2 around its perimeter. The bottom ends of the four support columns 2 are connected to the top of the calcining furnace body 1. A control panel 101 is installed on the side wall of the calcining furnace body 1. The control panel 101 is electrically connected to the crushing motor 5 and the feeding motor 801. The four support columns 2 firmly support the crushing box 3 on the top of the calcining furnace body 1, ensuring the stability of the crushing box 3 during operation. The installation of the control panel 101 allows the operator to easily monitor and control the operating status of the crushing motor 5 and the feeding motor 801.

[0031] Although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
