Description

Technical Field

[0001] This utility model belongs to the field of heat exchange equipment, specifically a ridge-type uniform heat exchange equipment for solid powder. Background Technology

[0002] Heat exchange equipment is an indispensable key equipment in industrial production and energy utilization. Its main function is to realize the heat transfer between two or more fluids to meet the temperature requirements of the process or to recover waste heat. In many industries such as chemical, building materials, metallurgy, and food, solid powders often need to be heated, cooled, dried or calcined, and heat exchange equipment is one of the key equipment to realize these processes.

[0003] A ridge-type solid powder heat exchanger is a device specifically designed for heat exchange between solid powder and fluid. "Ridge-type" refers to the special structure of the heat exchange surface inside the device. This structure is similar to the ridge of a house. By arranging the powder at an incline, a ridge-shaped slope is formed, allowing the solid powder to flow along the slope under gravity, forming a uniform thin layer. Simultaneously, it indirectly exchanges heat with the heat exchange medium. The ridge-type design allows for full contact between the powder and the heat exchange elements. However, when the powder flows within the ridge-shaped flow channel, local accumulation or excessively rapid flow may occur, leading to uneven heat exchange and affecting the heat exchange effect of the powder.

[0004] In summary, this utility model provides a ridge-type uniform heat exchange device for solid powder to solve the above-mentioned problems. Utility Model Content

[0023] Example 1

[0024] like Figure 1-4 The image shown is the first embodiment of this utility model. This embodiment provides a ridge-type solid powder uniform heat exchange device, including,

[0025] The heat exchange unit 1 includes a ridge-shaped shell 101, a feeding hopper 102 fixedly connected to the top of the ridge-shaped shell 101, a feeding port 103 opened at the bottom of the inner cavity of the feeding hopper 102, a discharge port 104 fixedly connected to both sides of the bottom of the ridge-shaped shell 101, a heat exchange tube bundle 105 disposed on both sides of the bottom of the ridge-shaped shell 101, and a base 106 fixedly connected to the bottom of the ridge-shaped shell 101.

[0026] The cleaning component 2 includes a motor 201 disposed on both sides of the inner cavity of the ridge-shaped housing 101, a rotating column 202 connected to the output shaft of the motor 201, a scraper 203 disposed on one side of the rotating column 202, a fixing ring 204 fixedly connected to the front and rear ends of the surface of the rotating column 202, one end of the scraper 203 being fixedly connected to the fixing ring 204, an adjustment component 205 disposed on the back of the ridge-shaped housing 101, and a mounting component 206 disposed on the surface of the adjustment component 205.

[0027] like Figure 1-4 As shown, the ridge-shaped shell 101 utilizes its ridge-shaped structure to increase the flow path of the powder, extend the heat exchange time, collect the powder at the top, and discharge it from both sides of the bottom, forming a uniform material layer, improving heat exchange efficiency, reducing dead zones for powder accumulation, and lowering the risk of agglomeration. The feeding hopper 102 stores the powder, and the feeding ports 103 are evenly distributed to control the feeding speed. The conical design prevents powder blockage. The discharge ports 104 are symmetrically arranged to ensure uniform powder discharge. The heat exchange tube bundle 105 is embedded in the bottom of the shell, indirectly contacting the powder for heat transfer. The heat exchange tube bundle 105 adopts a finned structure, and the base 106... Used to support the equipment and isolate high temperatures, the interior is filled with ceramic fiber. Motor 201 drives rotating column 202 to rotate, which drives scraper 203 to clean the inner wall of the housing. The surfaces of rotating column 202 and scraper 203 are sprayed with ceramic coating. Scraper 203 fits against the inner wall of the housing to remove adhering powder. Fixing ring 204 ensures that scraper 203 rotates synchronously with rotating column 202. Adjustment component 205 is used to adjust the height of scraper 203 to thoroughly scrape off residual powder. Installation component 206 is used to remove and install baffle 2051 for maintenance of components on its surface.

[0028] Example 2

[0029] Reference Figure 2 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0030] In this embodiment, the adjustment component 205 includes a baffle 2051 detachably connected to the back opening of the ridge-shaped housing 101, a fixing frame 2052 fixedly connected to the upper and lower ends of the front of the baffle 2051, a threaded rod 2053 movably connected between the two fixing frames 2052 via bearings, and a servo motor 2054 fixedly connected to the bottom of the lower fixing frame 2052. The output shaft of the servo motor 2054 passes through the lower fixing frame 2052 and is drivenly connected to the lower end of the threaded rod 2053.

[0031] The adjustment assembly 205 also includes a threaded plate 2055 threaded to the surface of the threaded rod 2053, a motor 201 fixedly connected to the front of the threaded plate 2055, and a limiting post 2056 slidably connected to the inner cavities on both sides of the threaded plate 2055. The top and bottom of the limiting post 2056 are fixedly connected to the fixing frame 2052.

[0032] like Figure 2 As shown, the baffle 2051 is used to support and fix the components on the front, and the components can be removed by disassembling the baffle 2051 for regular maintenance. The servo motor 2054 is used to drive the threaded rod 2053 to rotate, and the threaded rod 2053 drives the threaded plate 2055 to move up and down. The height of the motor 201 is adjusted to control the working height of the scraper 203. The limit post 2056 is used to prevent the threaded plate 2055 from deviating and to ensure the stability of the scraper 203 trajectory.

[0033] Example 3

[0034] Reference Figure 3 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0035] In this embodiment, the mounting component 206 includes a movable groove 2061 formed at the top and bottom of the baffle 2051, a movable frame 2062 slidably connected to the inner cavity of the movable groove 2061, and a slot 2063 formed at the top and bottom of the inner cavity of the roof-shaped housing 101. One end of the movable frame 2062 extends into the inner cavity of the slot 2063 and engages with its inner cavity.

[0036] Mounting assembly 206 also includes a stainless steel compression spring 2064 fixedly connected to one side of the two slots 2063, the end of the stainless steel compression spring 2064 away from the movable frame 2062 being fixedly connected to the inner wall of the movable slot 2061, and receiving slots opened at the upper and lower ends of the back of the baffle 2051, the back of the movable frame 2062 extending to the back of the baffle 2051 through the receiving slots.

[0037] like Figure 3 As shown, the movable slot 2061 is used to accommodate the movable frame 2062 and provide space for the movable frame 2062 to move. The movable frame 2062 slides in the movable slot 2061, realizing the quick assembly and disassembly of the baffle 2051. The locking slot 2063 and the movable frame 2062 have a locking structure, which can be disassembled without tools. The stainless steel compression spring 2064 provides preload to prevent loosening.

[0038] In use, powder is added to the interior of the ridge-shaped shell 101 through the feeding hopper 102. The added powder is evenly added to the ridge-shaped shell 101 through the feeding port 103. Since the ridge-shaped shell 101 is a continuous pile, the powder can slide down under the action of gravity and complete the heat exchange work during the operation of the heat exchange tube bundle 105. After heat exchange, the powder is discharged through the discharge port 104. When there is powder accumulation on the inner wall of the ridge-shaped shell 101 or the residual powder is too thick, the motor 201 is started by the external controller, so that its output shaft drives the rotating column 202 to rotate. When the rotating column 202 rotates, it can adjust the angle of the scraper 203 in conjunction with the fixing ring 204 until the scraper 203 is in contact with the ridge-shaped shell 101. The inner wall of the 101 is contacted, then the motor 201 is turned off and the servo motor 2054 is started. The servo motor 2054 can drive the threaded rod 2053 to rotate. When the threaded rod 2053 rotates, it can adjust the height of the threaded plate 2055, thereby adjusting the height of the motor 201, the rotating column 202 and the scraper 203, so that the scraper 203 can fully scrape off the residue on the inner wall of the ridge-shaped housing 101. When the cleaning component 2 needs to be disassembled and maintained, the movable frame 2062 is pressed to move it into the movable groove 2061 until it is removed from the inside of the slot 2063. Then the baffle 2051 can be removed from the opening on the back of the ridge-shaped housing 101 for maintenance of the components of the cleaning component 2.
