Description

Technical Field

[0001] This utility model relates to an embedded water tank mechanical tumbling and scraping powdery material cooling machine, belonging to the technical field of powdery material cooling devices. Background Technology

[0002] Utility model patent ZL202322899241.1 discloses a mechanically scraped powdery material cooler, including a cooler housing, vertically arranged cooling water pipes inside the cooler, and a scraping device horizontally arranged on the outer wall of the cooling water pipes. The mechanical scraping device is connected to a hydraulic cylinder at the top of the cooler housing, and a spray cooling device or a shell circulating water jacket cooling device is provided outside the cooler housing. At the bottom of the cooler housing, an air-filled box with a permeable layer is provided in the gaps between the water pipes of the cooler housing, and the air-filled box is connected to a Roots blower through branch air pipes and a main air pipe.

[0003] Some problems were found in the actual operation of this utility model. Because the cooling water pipes are placed vertically, the bends of the water pipes need to pass through the top and bottom of the cooling box. As a result, the air filling box needs to be set in the gaps between the cooling water pipes, instead of forming a complete whole. This will cause the material to be insufficiently gasified in some areas because the air filling box cannot reach them, resulting in excessive resistance of the dust removal device.

[0004] Of course, such problems can be solved by setting up a separate small air box or air rod. However, this would make the air supply structure cumbersome. In addition, since the dust removal device uses a hydraulic cylinder for reciprocating dust removal from above, the cooling box should not be made too tall due to the limited reciprocating stroke. Otherwise, the material at the bottom of the cooling box will not be able to achieve sufficient heat exchange with the upper part, and the heat exchange area of ​​the water pipes will be small, resulting in low cooling efficiency at large cooling volumes. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an embedded water tank mechanical tumbling and scraping powder material cooler with a large heat exchange area, high efficiency and good cooling effect for powder materials.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: an embedded water tank mechanical agitation and scraping cooling machine for powdery materials, comprising a box body, an air-filled box, a mechanical agitation device, and a cooling water tank.

Multiple long strip-shaped scraper frames are set parallel to the main shaft, fixed at intervals in the circumferential direction of the chain drive assemblies, and rotate around the main shaft and the lower shaft under the drive of the chain drive assemblies. Multiple scrapers are fixed on each scraper frame.

[0007] The multiple cooling water tanks are arranged in two rows on both sides of the main shaft and the lower shaft, and the two rows of cooling water tanks are aligned and fixed at equal intervals on the inner walls of both sides of the tank body.

[0008] The multiple scrapers on the scraper frame correspond to the gaps in the cooling water tank and are inserted into the gaps in the cooling water tank.

[0009] Furthermore, among the multiple scrapers between every two cooling water tanks, one scraper is equipped with two nylon plates. The two nylon plates are located between the pressure plate and the scraper and are pressed together by two rows of connecting bolts. The bolt holes on the two nylon plates are all adjustment elongated holes.

[0010] Furthermore, the cooling water tank is flat, with its bottom extending towards the middle of the tank body, making the side of the cooling water tank L-shaped.

[0012] Furthermore, an exhaust pipe is also provided on the top of the cooling water tank.

[0013] Furthermore, the chain drive assembly includes an upper sprocket, a lower tail pulley, and a chain. The upper sprocket is fixed on the main shaft, the lower tail pulley is fixed on the lower shaft, and the chain connects the upper sprocket and the lower tail pulley.

[0014] Furthermore, the bottom of the housing is also provided with two stirring shafts parallel to the main shaft. Both stirring shafts are rotatably mounted on the housing through stirring bearing seats. Multiple stirring blades are spaced apart on the stirring shafts. A stirring shaft sprocket is fixed at each end of the stirring shaft, and a transmission sprocket is fixed at each end of the main shaft. The stirring shaft sprockets are connected to the transmission sprockets through stirring shaft chains.

[0015] Furthermore, the air box is equipped with a horizontal air distribution baffle, and multiple small air distribution holes are evenly distributed on the air distribution baffle. The top of the air box is a sieve plate, and the bottom surface of the sieve plate is equipped with a breathable cloth and reinforcing ribs.

[0016] A main air inlet pipe connected to a fan is provided at the bottom or side of the box body. Multiple branch air inlet pipes are provided at intervals on the main air inlet pipe, and the multiple branch air inlet pipes are connected to the bottom of the inflation box.

[0035] The present invention provides the following embodiments.

[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, this utility model discloses an embedded water tank mechanical agitation and scraping cooling machine for powdery materials, comprising a housing 1, an air-filled box 2, a mechanical agitation device, and a cooling water tank 3. The top of the housing 1 has a feed inlet 4 and a dust collection inlet 5, the upper part of the side wall has a discharge outlet 6, and the lower part of the side wall has multiple slag removal inlets 7 spaced apart. The bottom of the housing 1 is connected to the air-filled box 2 with a breathable layer. Multiple cooling water tanks 3 and a mechanical agitation device are installed inside the housing 1. The mechanical agitation device includes a main shaft 8, a lower shaft 9, a chain drive assembly, a scraper frame 10, and scrapers 11. The horizontally arranged main shaft... The main shaft 8 is rotatably mounted in the upper part of the housing 1 via the upper bearing seat 12. One end of the main shaft 8 extends out of the housing 1 as the input shaft. The lower shaft 9 is arranged parallel to the lower part of the main shaft 8 and is rotatably mounted on the housing 1 via the lower bearing seat 13. The main shaft 8 is connected to the lower shaft 9 via at least two sets of chain drive assemblies and drives the lower shaft 9 to rotate. Multiple long strip-shaped scraper frames 10 are arranged parallel to the main shaft 8, fixed at intervals in the circumferential direction of the chain drive assembly, and rotate around the main shaft 8 and the lower shaft 9 under the drive of the chain drive assembly. Multiple scrapers 11 are fixed on each scraper frame 10.

[0037] The plurality of cooling water tanks 3 are divided into two rows located on both sides of the main shaft 8 and the lower shaft 9, and the two rows of cooling water tanks 3 are aligned and fixed at equal intervals on the inner walls of both sides of the housing 1.

[0038] The multiple scrapers 11 on the scraper frame 10 correspond to the gaps in the cooling water tank 3 and are inserted into the gaps in the cooling water tank 3.

[0039] The shaft end of the main shaft 8 extending out of the housing 1 is connected to an external drive device. Under the drive of the external drive device, the entire mechanical tilting device operates.

[0040] Positioning holes are provided on the inner walls of both sides of the housing 1. The cooling water tank 3 is welded to the flat steel and then fixed to the inner walls of both sides of the housing 1 with bolts. The two rows of cooling water tanks 3 are arranged vertically, evenly, and with equal spacing. The positioning holes on the inner walls of both sides of the housing 1 must be accurately positioned, and the deviation must be within the allowable range.

[0041] like Figure 5 , Figure 6 As shown, among the multiple scrapers 11 between each pair of cooling water tanks 3, one scraper 11 is equipped with two nylon plates 14. The two nylon plates 14 are located between the pressure plate 15 and the scraper 11 and are pressed together by two rows of connecting bolts 16. The bolt holes on the two nylon plates 14 are all adjustment elongated holes.

[0042] The gap between the nylon plate 14 and the cooling water tank 3 can be adjusted by adjusting the elongated hole and connecting bolt 16 to perform the ash scraping operation on the cooling water tank 3. The nylon plate 14 is specially designed to clean the condensate on the inner wall of the tank 1 and the outer wall of the cooling water tank 3. The purpose is to ensure good heat exchange efficiency between the powdery material and the cooling water tank 3. The scrapers 11 that are not equipped with nylon plates 14 serve to turn and stir the material and do not have the function of ash scraping.

[0043] The nylon sheet 14 is a high-temperature resistant nylon sheet.

[0044] like Figure 7 , Figure 8 As shown, the cooling water tank 3 is flat, and its bottom extends towards the middle of the tank body 1, making the side of the cooling water tank 3 L-shaped. This further increases the heat exchange area of ​​the cooling water tank 3.

[0045] Each of the cooling water tanks 3 is connected to an inlet pipe 17 and an outlet pipe 18 at its top. The inlet pipe 17 extends into the bottom of the cooling water tank 3. A main inlet pipe and a main outlet pipe are provided on the top of the tank body 1. The inlet pipe 17 on each cooling water tank 3 is connected to the main inlet pipe, and the outlet pipe 18 is connected to the main outlet pipe.

[0046] The main inlet and outlet water pipes are connected to the cooling pool. The circulating cooling water in the cooling pool enters the bottom of the cooling water tank 3 through a pump, valve, main inlet water pipe, and inlet pipe 17, where it exchanges heat with the gasified material in the tank 1. Then, it returns to the cooling pool through outlet pipe 18 and the main outlet water pipe. When this utility model is not in use during winter, the circulating water in the cooling water tank 3 can be extracted through the inlet water pipe 17 that extends to the bottom of the cooling water tank 3.

[0047] Each of the cooling water tanks 3 is provided with an exhaust pipe 34 on its top, and the outlet end of the exhaust pipe 34 extends out of the tank body 1.

[0048] like Figure 1As shown, the chain drive assembly includes an upper sprocket 19, a lower tail pulley 20, and a chain 21. The upper sprocket 19 is fixed on the main shaft 8, the lower tail pulley 20 is fixed on the lower shaft 9, and the chain 21 connects the upper sprocket 19 and the lower tail pulley 20.

[0049] like Figure 1 , Figure 3 As shown, the bottom of the housing 1 is also provided with two stirring shafts 22 parallel to the main shaft 8. Both stirring shafts 22 are rotatably mounted on the housing 1 through stirring bearing seats 23. Multiple stirring blades 24 are arranged at intervals on the stirring shafts 22. A stirring shaft sprocket 25 is fixed at each end of the stirring shaft 22, and a transmission sprocket 26 is fixed at each end of the main shaft 8. The stirring shaft sprockets 25 are connected to the transmission sprockets 26 through stirring shaft chains 27.

[0050] On both sides of the bottom of the box 1, where the scraper 11 cannot turn over, the two stirring shafts 22 can stir up this part of the dead or cold material, so that it can be mixed with the hot material coming down from the top. After being cooled by the cooling water tank 3, it is discharged out of the box 1.

[0051] like Figure 9 , Figure 10 As shown, the air box 2 is provided with a horizontal air distribution baffle 28 inside, and a plurality of small air distribution holes 29 are evenly distributed on the air distribution baffle 28. The top of the air box 2 is a sieve plate 30, and the bottom surface of the sieve plate 30 is provided with a breathable cloth and a reinforcing rib 31.

[0052] A main air inlet pipe 32 connected to a fan is provided on the lower or side of the housing 1. Multiple branch air inlet pipes 33 are provided on the main air inlet pipe 32 at intervals, and the multiple branch air inlet pipes 33 are connected to the bottom of the inflation box 2.

[0053] A Roots blower can be used as the blower. The high-pressure air output by the Roots blower enters the air filling box 2 through the main air inlet pipe 32 and the branch air inlet pipe 33. Then, it enters the box body 1 through the air distribution holes 29 on the air distribution baffle 28, the air-permeable cloth, and the sieve plate 30. The powder in the box body 1 is gasified, so that the powder can be fully mixed under the action of the mechanical turning device.

[0054] The working principle and process of this utility model are as follows.

[0055] Start the fan, cooling water pump and external drive unit.

[0056] The high-pressure air output by the blower enters the air filling box 2 through the main air inlet pipe 32 and the branch air inlet pipe 33, and then enters the box body 1 through the air distribution holes 29 on the air distribution baffle 28, the breathable cloth, and the sieve plate 30 to gasify the powder in the box body 1.

[0057] The cooling water pump pumps the circulating cooling water in the cooling pool into the cooling water tank 3 through the main water inlet pipe and the main water inlet pipe 17, where it exchanges heat with the gasified material in the tank 1, and then returns to the cooling pool through the water outlet pipe 18 and the main water outlet pipe.

[0058] An external drive unit rotates the main shaft 8, which in turn drives the lower shaft 9 to rotate via a chain drive assembly. Simultaneously, a scraper frame 10 with perforated scrapers 11, fixed to the chain drive assembly, rotates around the main shaft 8 and the lower shaft 9. The scrapers 11 are inserted into the gap in the cooling water tank 3, effectively agitating and mixing the materials. The powder that has just flowed into the tank 1 is agitated, tumbled, flowed, and mixed with the powder below through the mechanical agitation device. This allows some of the powder above to enter the lower part, and the powder below to rise and mix with some of the hot material before being discharged, resulting in more efficient heat exchange between the powder and the cooling water tank 3. Furthermore, the scrapers 11 with nylon plates 14 also serve to clean condensate from the inner wall of the tank 1 and the outer wall of the cooling water tank 3.

[0059] At the bottom sides of the box 1, in areas that the scraper 11 cannot reach, the stirring shaft 22 rotates under the drive of the main shaft 8, stirring up the dead or cold material in this area, mixing it with the hot material coming down from above, and then discharging it out of the box 1 after being cooled by the cooling water tank 3.

[0060] When this utility model is not in use during winter, the circulating water in the cooling water tank 3 can be extracted through the water inlet pipe 17 that extends into the bottom of the cooling water tank 3 to protect the cooling water tank 3 from freezing.

[0061] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
