Description

Technical Field

[0001] This utility model relates to a material cooling output device, and in particular to a horizontal roller compartmentalized membrane cold material machine, belonging to the field of mechanical equipment technology. Background Technology

[0002] A slag cooler (or slag cooler) is a commonly used industrial cooling and conveying equipment for high-temperature materials, such as steel slag, boiler slag, and high-temperature treated electrode materials. The feed temperature of these materials is often above 600 degrees Celsius, and in some cases even above 1000 degrees Celsius. After processing by the slag cooler, the discharge temperature is generally no higher than 100 degrees Celsius. Currently, the horizontal drum-type slag cooler is the mainstream type used in industry. Existing slag coolers generally include a base, and two tracks fixed around the drum body. The slag is placed on the support rollers of the base. The roller is connected to a gear ring or sprocket. The drive mechanism (motor and reducer) drives the roller to rotate through the gear ring or sprocket. The roller has a double-layer structure. There is a water jacket between the inner and outer walls of the roller. Cooling water is placed in the water jacket to cool the slag. The cooling water enters the water jacket of the roller through a rotary joint. Spiral slag guide plates are welded on the inner wall of the roller. The slag inlet pipe extends into the roller from the feed pipe of the cylinder. The discharge pipe is located at the rear end of the cylinder. The motor and reducer drive the roller to rotate. The high-temperature slag enters the roller from the slag inlet pipe and is discharged from the slag outlet after being cooled. In Chinese patent application literature, the slag cooler disclosed in application number CN2023200072714, the slag cooler disclosed in CN109899816A, the temperature-controlled slag cooler disclosed in CN109899821A, and the silencer slag cooler disclosed in CN109899820A all include some or all of the above-mentioned structures. The main aspects of the existing slag coolers that need improvement and optimization in use are: First, during the conveying process, the contact area between the high-temperature material and the cooling medium is small, generally located at the bottom of the cylinder, which leads to low heat exchange efficiency and limits the processing capacity of the equipment; Second, in many cases, the material will adhere to the inner wall of the jacketed drum, which will reduce the thermal conductivity of the inner wall and affect the cooling effect. Summary of the Invention

[0003] The purpose of this invention is to overcome the above-mentioned problems of current cold material machines and to provide a horizontal roller compartmentalized membrane cold material machine.

[0004] To achieve the purpose of this utility model, the following technical solution is adopted: A horizontal drum-type membrane cooling machine includes a base, on which multiple sets of support rollers are rotatably mounted. A track is fixedly connected to the outer wall of the drum with a water jacket, and the track is located on the support rollers. A gear ring is fixedly connected to the outer peripheral wall of the drum, and a gear meshes with the gear ring. The gear is connected to a drive mechanism. A feed box is rotatably connected to the feed end of the drum, and a discharge box is rotatably connected to the discharge end. The feed box and discharge box are sealed to the drum. A spiral pusher is fixedly connected to the inner peripheral wall of the drum. Multiple radial membrane cooling walls are fixedly arranged inside the drum. The pusher is discontinuous and located on a fan-shaped wall formed by two adjacent membrane cooling walls. The membrane cooling wall includes a water inlet manifold located at the discharge end along the radial direction of the drum and a water outlet manifold located at the feed end along the radial direction of the drum. Multiple axial hot water exchange pipes are connected between the water inlet manifold and the water outlet manifold, and steel plates are welded between the hot water exchange pipes. Each membrane cooling wall has an inlet manifold with its inner end connected to the inlet water passage and its outer end closed. Each membrane cooling wall has an outlet manifold with its outer end connected to the water jacket and its inner end closed. A water jacket is fixedly installed at the center of the discharge end drum. The water jacket consists of an outer pipe and an inner pipe located inside the outer pipe. A double-rotary joint is connected to the water jacket. The inlet manifolds are all connected to the jacket between the outer and inner pipes. A radial return water pipe is connected to the inner pipe. The radial outer end of the return water pipe is connected to the water jacket of the drum. The inlet pipe of the cooler is connected to the jacket through the rotary joint. Multiple striking mechanisms are installed on the roller. The striking mechanism includes a radial track pipe that passes through the outer wall of the drum and has its inner end welded to the outer surface of the inner wall of the drum. The outer end of the radial track pipe that extends out of the outer wall of the drum is connected to a tangential pipe. The radial track pipe and the tangential pipe are connected. The radial track pipe and the outer wall of the drum are sealed and welded. A steel ball is freely placed in the radial track pipe and can roll freely in the radial and tangential tracks.

[0005] Furthermore, the striking mechanism is distributed in circles on the roller, with each circle containing multiple striking mechanisms evenly distributed along the circumference of the roller, and the striking mechanism has multiple circles on the roller.

[0006] Furthermore, multiple steel scrapers are axially hinged to the outer wall of the heat exchange pipe at the outermost radial end of each membrane cooling wall, and the scrapers are located in the gap between the membrane cooling wall and the inner wall of the drum.

[0007] Furthermore, multiple guide plates are welded onto the steel plate of the membrane cooling wall. The guide plates are distributed obliquely in the front and back directions. When the drum rotates, the guide plates exert a backward thrust on the material. The height of the guide plates is 60mm to 90mm.

[0008] Furthermore, the membrane cooling wall consists of 3 to 8 sections, with three to eight compartments.

[0009] The beneficial technical effects of this utility model are as follows: During cooling and conveying, this compartmentalized cold material machine can divide the material into multiple fan-shaped compartments formed between two adjacent membrane cooling walls and the inner cylinder, resulting in a three-dimensional multi-compartment distribution of the material within the drum. Furthermore, heat exchange can occur on all three surfaces, leading to high heat exchange efficiency. The striking mechanism uses steel balls to vibrate and remove material adhering to the inner wall of the drum. The scraper blades can scrape off material adhering to a corresponding range during drum rotation. A detailed description is provided in conjunction with specific implementation methods.

[0017] As shown in the attached diagram, a horizontal drum-type membrane cooling machine includes a base 1 with multiple sets of support rollers 4 rotatably mounted on it. A track 3 is fixedly connected to the outer wall of a water-jacketed drum 2, located on the support rollers 4. A gear ring 5 is fixedly connected to the outer peripheral wall of the drum, and a gear 6 meshes with the gear ring. The gear is connected to a drive mechanism, which uses a motor 7 to drive a reducer. The reducer drives the gear. A feed box is rotatably connected to the feed end of the drum, and a discharge box is rotatably connected to the discharge end. Both the feed box and the discharge box are sealed to the drum. A spiral pusher 17 is fixedly connected to the inner peripheral wall of the drum. This is a known structure of existing cooling machines. Multiple radial membrane cooling walls (membrane heat exchange walls) are fixedly arranged inside the drum, with 3 to 6 membrane cooling walls, the number of which is equal to the number of compartments. Figure 2 , Figure 3The embodiment uses six membrane cooling walls. The pusher plates 17 are discontinuous in the circumferential direction and are located on the fan-shaped wall formed by two adjacent membrane cooling walls. The membrane cooling wall includes an inlet manifold 12 located at the discharge end along the radial direction of the drum and an outlet manifold located at the feed end along the radial direction of the drum. The outlet manifold is not shown in the figure. The outlet manifold and the inlet manifold are directly opposite each other in the front-to-back direction (they are on the same straight line in the front-to-back projection). Multiple axial heat exchanger pipes 14 are connected between the inlet manifold and the outlet manifold. Steel plates are welded between the heat exchanger pipes. Multiple guide plates 16 are welded to the steel plate of the membrane cooling wall. The guide plates are obliquely distributed front-to-back. When the drum rotates, the guide plates generate a backward pushing force on the material. The height of the guide plates is 60mm to 90mm. The inner end of the inlet manifold 12 on each membrane cooling wall is connected to the water inlet channel and the outer end is closed. The outer end of the outlet manifold on each membrane cooling wall is connected to the water jacket 13. The inner and outer ends are closed. The water inlet manifold is close to the discharge end, and the water outlet manifold is close to the inlet end. A water channel sleeve 10 is fixedly installed at the center of the discharge end drum. The water channel sleeve consists of an outer pipe and an inner pipe located in the outer pipe. A double-rotary joint 11 is connected to the water channel sleeve. The water inlet manifold is connected to the jacket between the outer pipe and the inner pipe. A radial return water pipe 18 is connected to the inner pipe. The radial outer end of the return water pipe is connected to the water jacket 13 of the drum. The water inlet pipe of the cold material machine is connected to the jacket (between the inner pipe and the outer pipe) through the rotary joint. Multiple striking mechanisms are installed on the roller. The striking mechanism includes a radial track pipe 19 that passes through the outer wall of the drum and is welded to the outer surface of the inner wall of the drum. The outer end of the radial track pipe 19 that extends out of the outer wall of the drum is connected to a tangential pipe 20. The radial track pipe is connected to the tangential pipe. The radial track pipe is sealed and welded to the outer wall of the drum. A steel ball is freely placed in the radial track pipe. The steel ball can roll freely in the radial track pipe and the tangential pipe. During drum rotation, steel balls fall freely from the upper radial track, impacting the inner wall of the drum and causing adhering material to detach, thus preventing material adhesion. The striking mechanism is distributed in concentric circles on the drum, with each circle containing multiple striking mechanisms evenly distributed along the drum's circumference. As a further optimization, multiple steel scrapers 15 are axially hinged to the outer wall of the heat exchange pipe at the outermost radial end of each membrane cooling wall, positioned in the gap between the membrane cooling wall and the inner wall of the drum. During drum rotation, the material presses against the scrapers at different angles, creating different rotational directions. The rotation of the scrapers allows for scraping away thicker layers of material adhering within a corresponding range. Since all compartments are identical, the material flow between compartments from the scrapers during rotation does not affect the material quantity within each compartment and also promotes material homogenization.

[0018] The working process of this cooling machine is the same as that of existing cooling machines. Under uniform feeding conditions, the material is basically evenly distributed into each compartment. As the drum rotates, the material continuously moves towards the discharge end under the action of the pusher and guide plates. Heat exchange can occur on three surfaces of each compartment, thus cooling the material being conveyed. The cooling water flow is as follows: water inlet, rotary joint, jacket, water inlet manifold, hot water exchange pipe, water outlet manifold, water jacket, return pipe, inner pipe, and water outlet.

[0019] The inlet water temperature is generally not higher than 30 degrees Celsius, and the outlet water temperature is not lower than 50 degrees Celsius. The inner and outer walls of the drum can be made of 12mm steel plate. The hot water exchange pipe and the inner and outer walls of the drum can be made of 12Cr1Mov alloy material. The slag guide plate can be made of 1Cr13 material.

[0020] After a detailed description of the embodiments of this utility model, those skilled in the art will clearly understand that various changes and modifications can be made without departing from the scope and spirit of the above-mentioned patent applications. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the scope of the technical solution of this utility model, and this utility model is not limited to the embodiments of the examples given in the specification.
