Description

Technical Field

[0001] This utility model relates to the field of clinker quenching technology, specifically a cement kiln clinker quenching device. Background Technology

[0002] Cement is a powdered, hydraulic, inorganic binder. When mixed with water, it forms a paste that hardens in air or water, and can firmly bind materials such as sand and stone together. It is the type of cement commonly used in civil engineering projects. General-purpose cements mainly refer to: silicate cement, ordinary silicate cement, slag silicate cement, pozzolanic silicate cement, fly ash silicate cement, and composite silicate cement. During cement production, the calcined raw materials need to be rapidly cooled.

[0003] In response, Chinese patent application number CN215810245U discloses a high-temperature clinker cooling device for dry-process cement kilns, comprising a shell and a blower. A feed inlet is installed at one side of the top of the shell. An air-cooled chamber A is installed at the bottom of the shell, next to the feed inlet, via a partition wall. Air-cooled chambers B, C, D, E, and F are also installed at the bottom of the shell, next to air-cooled chamber E, via a partition wall. A fixed grate is installed near the top of air-cooled chamber A. This invention solves the problems of material leakage, low cooling efficiency, high energy consumption, and high failure rate inherent in existing devices, demonstrating the high efficiency, low energy consumption, and practicality of high-temperature clinker cooling in dry-process cement kilns.

[0004] However, in actual use, when cooling cement clinker, the clinker cannot be tilted for cooling and conveying, which shortens the overall cooling time and results in poor cooling effect. At the same time, the air volume of the blower cannot be adjusted during use. Therefore, improving and perfecting the above-mentioned problems has become an urgent issue to be addressed. Summary of the Invention

[0005] The purpose of this utility model is to provide a cement kiln clinker rapid cooling device to solve the problems mentioned in the background art, such as the inability to tilt and transport the clinker for cooling, resulting in a shorter overall cooling time and poor cooling effect, and the inability to adjust the air volume of the blower during use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cement kiln clinker quenching device, comprising a base body, an outer shell body mounted on the upper surface of the base body, a side block mounted on the upper surface of the base body, a quenching inclined plate mounted on the back of the side block, and a first inclined block and a second inclined block mounted sequentially from front to back on the surface of the quenching inclined plate.

[0007] A fixed grate is installed on the back of the quenching inclined plate. A blower body is installed inside the base body and installed on the lower surface of the quenching inclined plate. A stabilizing ring is installed on the upper surface of the blower body and a connecting pipe is installed inside the stabilizing ring. A conveying box is provided at the upper end of the connecting pipe.

[0008] Preferably, the top surface of the conveying box is provided with a conveying hole, and the top surface of the blower body is equipped with a side plate.

[0009] Preferably, a telescopic rod is installed on the left side surface of the side plate, and a sliding plate is installed at the end of the telescopic rod away from the side plate.

[0010] Preferably, the sliding plate is inserted and installed inside the conveyor box, and the inside of the conveyor box is a cavity.

[0011] Preferably, the upper surface of the outer shell body is equipped with a feed cylinder and a waste heat outlet pipe from front to back.

[0012] Preferably, the inner wall top surface of the outer shell body is equipped with guide ramps, and three sets of guide ramps are provided.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This cement kiln clinker quenching device comprises a base body, outer shell body, side blocks, quenching inclined plate, first inclined block, second inclined block, fixed grate, blower body, stabilizing ring, connecting pipe, conveying box, conveying hole, side plate, and telescopic rod. In operation, cement clinker enters the feed cylinder through the kiln inlet and then falls onto the surface of the quenching inclined plate. Because the quenching inclined plate is inclined, and its surface is equipped with the first and second inclined blocks, the clinker travels a longer path on the plate, thus facilitating cooling and improving heat recovery efficiency. The blower body then pumps air into the connecting pipe, which flows through the conveying box and out through the conveying hole. Activating the telescopic rod moves a sliding plate within the conveying box, allowing the sliding plate to block the conveying hole and adjust the airflow, demonstrating the design's practicality.

[0015] This cement kiln clinker quenching device, consisting of an outer shell, a feed cylinder, a waste heat outlet pipe, and guide ramps, guides and conveys clinker through the feed cylinder during operation. Simultaneously, the waste heat outlet pipe releases waste heat from the base and outer shell. The shoe-shaped design of the guide ramps ensures airflow is directed along their position, allowing cooling air to be conveyed along the ramps. This guiding design of the ramps prolongs the contact time between the cooling air and the clinker, enabling rapid quenching of the conveyed material and demonstrating the device's functionality.

[0021] 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.

[0022] Please see Figure 1-4 One embodiment provided by this utility model:

[0023] A rapid cooling device for cement kiln clinker is disclosed in this application. The outer shell 2, quenching inclined plate 4, fixed grate 7, blower body 8, telescopic rod 14, and waste heat outlet pipe 17 used in this application are all commercially available products. Their principles and connection methods are existing technologies well-known to those skilled in the art, and therefore will not be elaborated upon here. The device includes a base body 1, with the outer shell 2 mounted on its upper surface. Side blocks 3 are mounted on the upper surface of the base body 1, and the quenching inclined plate 4 is mounted on the back of the side blocks 3. A first inclined block 5 and a second inclined block 6 are sequentially mounted on the surface of the quenching inclined plate 4 from front to back. The upper surface of the outer shell 2 is sequentially mounted with… It has a feed cylinder 16 and a waste heat exhaust pipe 17. The inner wall top surface of the outer shell body 2 is equipped with guide inclined blocks 18. There are three sets of guide inclined blocks 18. The feed cylinder 16 can guide and convey the clinker. At the same time, the waste heat exhaust pipe 17 can exhaust the waste heat inside the base body 1 and the outer shell body 2. The shoe-shaped design of the guide inclined blocks 18 can make the air volume conveyed along the position of the guide inclined blocks 18, so that the cooling air is guided and conveyed along the guide inclined blocks 18. The guiding design of the guide inclined blocks 18 can make the contact time between the cooling air and the clinker longer, thereby enabling rapid cooling of the conveyed material.

[0024] A fixed grate plate 7 is installed on the back of the quenching inclined plate 4. A blower body 8 is installed inside the base body 1, and is mounted on the lower surface of the quenching inclined plate 4. A stabilizing ring 9 is installed on the upper surface of the blower body 8, and a connecting pipe 10 is installed inside the stabilizing ring 9. A conveying box 11 is installed at the upper end of the connecting pipe 10. A conveying hole 12 is opened on the top surface of the conveying box 11. A side plate 13 is installed on the top surface of the blower body 8, and a telescopic rod 14 is installed on the left side surface of the side plate 13. A sliding plate 15 is installed at the end of the telescopic rod 14 away from the side plate 13. The sliding plate 15 is inserted and installed inside the conveying box 11, which is a hollow cavity. Cement clinker enters the feed cylinder through the kiln inlet. The material will then fall onto the surface of the quenching inclined plate 4. Since the quenching inclined plate 4 is inclined and has a first inclined block 5 and a second inclined block 6, the path of the clinker on the surface of the quenching inclined plate 4 will be longer, which is beneficial to the cooling of the clinker and improves the heat recovery efficiency. Then, by starting the blower body 8, air is delivered into the interior of the connecting pipe 10. The air will then flow out through the conveying hole 12 through the conveying box 11. By starting the telescopic rod 14, the sliding plate 15 can be moved to slide inside the conveying box 11. The sliding plate 15 can block the conveying hole 12, thereby adjusting the amount of air delivered.

[0025] Working Principle: When using this device, the operator first connects it to an external power source to provide electrical support. Cement clinker enters the feed cylinder 16 through the kiln inlet and then falls onto the surface of the quenching inclined plate 4. Because the quenching inclined plate 4 is inclined, and its surface is equipped with a first inclined block 5 and a second inclined block 6, the clinker travels a longer path on the surface, thus facilitating cooling and improving heat recovery efficiency. Then, by starting the blower body 8, air is supplied to the connecting pipe 10. The air then flows out through the conveying hole 12 via the conveying box 11. Activating the telescopic rod 14 drives the sliding plate 15 to move along the conveying path. The inside of the feeding box 11 slides, thereby blocking the conveying hole 12 through the sliding plate 15, which can adjust the air volume of the conveying. The feed cylinder 16 can guide and convey the clinker, and the waste heat outlet pipe 17 can release the waste heat inside the base body 1 and the outer shell body 2. The shoe-shaped design of the guide inclined block 18 can make the air volume conveyed along the position of the guide inclined block 18, so that the cooling air is guided and conveyed along the guide inclined block 18. The guiding design of the guide inclined block 18 can prolong the contact time between the cooling air and the clinker, thereby enabling rapid cooling of the conveyed material. The above is the working principle of this utility model.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
