Description

Technical Field

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

[0002] Cement temperature is a crucial indicator in the cement production process. Excessive cement temperature often leads to false setting, which in turn causes gypsum dehydration, severely impacting the quality and workability of concrete. This can manifest as accelerated hydration, increased slump, and reduced compatibility with admixtures. Therefore, controlling cement temperature is of paramount importance.

[0003] In existing multi-tube combined spiral coolers, cement is fed to multiple tubular spiral coolers through a distributor. However, the cement that just exits the mill is at a high temperature, and the heat causes the fine powdery material to become charged, making it easy to adhere to the inner wall of the distributor, resulting in blockage of the feed inlet and thus affecting the cooling efficiency of the cement. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a cement cooling device to address the above-mentioned shortcomings.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: A cement cooling device includes a base, a collector, a distributor, and a screw conveyor. Multiple screw conveyors are mounted on the base and distributed circumferentially along the base. The discharge ports of all screw conveyors are connected to the collector, and the inlets of all screw conveyors are connected to the distributor. An outer cylinder covers the outer side of the screw conveyor's cylinder body, forming a jacket between the cylinder body and the outer cylinder body for cooling water flow. The outer cylinder body has a cooling water inlet and a cooling water outlet. The distributor includes a housing, a distributing cone, and a lifting mechanism. The top of the housing is connected to the feed chute. The housing is a hollow prism. The feed inlet of the spiral elevator is connected to the side of the housing. The distributing cone is disposed inside the housing. The lifting mechanism is disposed on the base and located at the bottom of the housing. The push rod of the lifting mechanism passes through the housing and is connected to the distributing cone. The lifting mechanism is used to drive the distributing cone to move up and down inside the housing.

[0006] Furthermore, the spiral elevator includes a cylinder, spiral blades, and a drive mechanism. The cylinder is mounted on a base, the spiral blades are rotatably mounted inside the cylinder, and the drive mechanism is mounted on the cylinder and is used to drive the spiral blades to rotate.

[0007] Furthermore, a plurality of heat exchange fins are provided on the outer side of the cylinder, the heat exchange fins being distributed along a cylindrical helix, and the axis of the cylindrical helix coinciding with the axis of the cylinder.

[0008] Furthermore, the heat exchange fins are arranged at an angle.

[0009] Furthermore, the base is provided with a mounting bracket for installing the lifting mechanism.

[0010] Furthermore, the material distribution cone includes multiple guide surfaces, which are inclined to the corresponding feed inlets.

[0011] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages: This application provides a distributing cone inside the housing of the distributor, and the distributing cone can move up and down inside the housing to scrape off the cement adhering to the housing of the distributor, so as to avoid cement accumulation and blockage of the feed inlet; This application provides multiple heat exchange fins on the outside of the spiral elevator cylinder, and the heat exchange fins are distributed along the cylindrical spiral line. On the one hand, this can improve the heat exchange efficiency between cement and cooling water, and on the other hand, it can guide the cooling water in the jacket, so that it spirals upward in the jacket and fully absorbs the heat of the cylinder.

[0017] Example 1 like Figure 1 and Figure 2 As shown, a cooling device for cement production includes a base 1, a distributor 2, a collector 3, and a screw conveyor 4.

[0018] like Figure 3 As shown, four spiral elevators 4 are provided on the base 1. The four spiral elevators 4 are distributed around the circumference of the base 1. Multiple spiral elevators 4 are distributed around the circumference of the base 1. The four spiral elevators 4 are distributed at the four corners of the rectangle. The spiral elevator 4 includes a cylinder 41, spiral blades 42 and a drive mechanism 43. The cylinder 41 is cylindrical and is vertically arranged on the base 1. The bottom of the cylinder 41 is provided with a feed port 4a and the top of the cylinder 41 is provided with a discharge port 4b. Bearing seats are provided at both the top and bottom of the cylinder 41. The spiral blades 42 are rotatably arranged inside the cylinder 41 through a rotating shaft and bearing seats. The drive mechanism 43 is located at the top of the cylinder 41, and the output end of the drive mechanism 43 is connected to the rotating shaft of the spiral blades 42. The drive mechanism 43 is used to drive the spiral blades 42 to rotate.

[0019] Specifically, the drive mechanism 43 includes a motor, a reducer, and a coupling. The motor and reducer are mounted on the frame at the top of the cylinder 41. The output end of the motor is connected to the input end of the reducer, and the output end of the reducer is connected to the shaft of the spiral blade 42 via the coupling.

[0020] The outer cylinder 41 is covered by an outer cylinder 5, and a jacket 51 for cooling water circulation is formed between the outer cylinder 5 and the cylinder 41. The outer cylinder 5 has a cooling water inlet 52 and a cooling water outlet 53. Specifically, it also includes a cooling system, which includes at least cooling water pipes, a cold water tank, a cooling tower, and a water pump. The water pump delivers water from the cold water tank to the jacket, where it absorbs heat and is then delivered to the cooling tower for cooling. After cooling, the water flows back to the cold water tank for reuse.

[0021] The collector 2 and the distributor 3 are located between the four screw elevators 4, with the distributor 3 located below the collector 2. The feed inlets 4a of all screw elevators 4 are connected to the distributor 3, the top of the distributor 3 is connected to the feed chute 6, the discharge outlets 4b of all screw elevators 4 are connected to the collector 2, and the bottom of the collector 2 is connected to the discharge chute 7.

[0022] The feeder 3 includes a housing 31, a feed cone 32, and a lifting mechanism 33. The top of the housing 31 is connected to the feed chute 6. The housing 31 is a hollow hexagonal prism. The four sides of the housing 31 are respectively connected to the feed inlet 4a of the screw conveyor 4. The feed cone 32 is disposed inside the housing 31, and the outer contour of the feed cone 32 is adapted to the inner wall contour of the housing 31. The lifting mechanism 33 is disposed on the base 1 and located at the bottom of the housing 31. The push rod of the lifting mechanism 33 passes through the housing 31 and is connected to the feed cone 32. The lifting mechanism 33 is used to drive the feed cone 32 to move up and down inside the housing 31. like Figure 5 As shown, specifically, the distributing cone 32 includes four guide surfaces 321, which are inclined toward the four feed ports 4a respectively, so as to guide the cement conveyed into the housing 31 to the four feed ports 4a respectively; a fixed frame 11 is provided on the base 1, the lifting mechanism 33 is a hydraulic cylinder, and the lifting mechanism 33 is fixedly installed on the fixed frame 11. After the push rod of the lifting mechanism 33 passes through the housing 31, it is connected to the bottom of the distributing cone 32.

[0023] During operation, the cement discharged from the mill is fed into the shell 31 through the feed chute 6, and then enters each feed port 4a along the guide surface 321, and enters the cylinder through the feed port 4a. The drive mechanism 43 drives the spiral blades 42 to rotate, thereby driving the cement out of the mill to rise spirally. Under centrifugal force, the cement will stick tightly to the inner wall of the cylinder 41 to exchange heat with the cooling water in the jacket 51 to cool the cement. The cooled cement rises to the top of the cylinder 41 and is discharged from the discharge port 4b into the collector 2, and finally discharged through the discharge chute 7.

[0024] During operation, the lifting mechanism 33 can drive the material distribution cone 32 to move up and down inside the housing 31 to remove the cement adsorbed on the inner wall of the housing 31, thus preventing the cement from accumulating inside the housing 31.

[0025] Example 2 This embodiment is an improvement on embodiment 1.

[0026] like Figure 4 As shown, in this example, a plurality of heat exchange plates 411 are provided on the outer side of the cylinder 41. The heat exchange plates 411 are inclined and all heat exchange plates 411 are distributed along a cylindrical spiral line. The axis of the cylindrical spiral line coincides with the axis of the cylinder 41.

[0027] When cooling water is introduced into the jacket through cooling water inlet 52, the cooling water will spiral upward under the guidance of heat exchange fins 411 to increase the residence time of the cooling water in the jacket 51, so that the cooling water can fully absorb the heat of the cylinder 41; and the heat exchange fins 411 can improve the heat exchange efficiency.
