Description

Technical Field

[0001] This utility model relates to a grinding device, specifically a combined grinding device, and belongs to the technical field of grinding devices. Background Technology

[0002] The cement production process includes steps such as raw material preparation, firing, grinding, and clinker preparation. During the grinding process, materials such as clinker and slag need to be ground, and then the ground clinker, slag, and pulverized coal are mixed in a certain proportion.

[0003] During the grinding stage, materials such as clinker and slag need to be ground to achieve certain fineness and particle size distribution requirements. This step is crucial for improving the activity, strength, and durability of cement. Currently, roller presses are one of the main pieces of equipment for grinding clinker. In large cement production workshops, multiple grinding roller presses are usually set up to operate simultaneously in order to improve production efficiency.

[0004] However, although these roller presses coexist, they operate independently and lack the necessary interoperability. This independence leads to a significant problem: after the initial grinding of clinker by the roller press, the clinker particles obtained are often difficult to meet production requirements directly. Due to the unevenness of particle size and distribution, multiple grinding processes are often required to achieve the ideal fineness and particle distribution. Therefore, a combined grinding device is proposed. Utility Model Content

[0005] In view of this, the present invention provides a combined grinding device to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial option.

[0006] The technical solution of this utility model embodiment is implemented as follows: a combined grinding device includes two grinding components, and the two grinding components are connected by a connecting component;

[0007] The connecting assembly includes a screw conveyor, a first hopper, an opening and closing cylinder, two feeding pipes, a sealing plate, a connecting plate, an L-shaped mounting base, a plug-in slot, a connecting pipe, and an extension pipe;

[0008] One end of the connecting pipe is installed at the discharge port of the screw conveyor, and the other end of the connecting pipe is connected to the extension pipe. The two discharge pipes are symmetrically fixedly connected to the outer side wall of the first discharge hopper, and one discharge pipe is connected to the feed port of the screw conveyor. The insertion slot is opened on the inner side wall of the discharge pipe, and the sealing plate is slidably connected to the inner side wall of the insertion slot. One side of the connecting plate is fixedly connected to the sealing plate, and the other side of the connecting plate is fixedly connected to the cylinder shaft of the opening and closing cylinder. The opening and closing cylinder is installed on one side of the L-shaped mounting base.

[0009] More preferably, the L-shaped mounting base is installed on the outer side wall of the first hopper.

[0010] More preferably, two guide rods are symmetrically fixedly connected to the side of the connecting plate away from the closing plate, and the guide rods are slidably connected inside the L-shaped mounting base.

[0011] More preferably, the grinding assembly includes a housing, a feed hopper, two geared motors, two grinding rollers, and two bearing seats;

[0012] The two grinding rollers are symmetrically located inside the housing. The grinding rollers are rotatably connected to the housing through two bearing seats. The feed hopper is installed on the top of the housing. The two geared motors are symmetrically installed on the front surface of the housing.

[0013] More preferably, the output shaft of the geared motor is fixedly connected to the roller shaft of the grinding roller.

[0014] More preferably, the two grinding components are arranged symmetrically on the left and right sides, with the first hopper installed at the bottom of the grinding component on the left side and the second hopper installed at the bottom of the grinding component on the right side.

[0015] More preferably, the extension tube is mounted on top of the grinding assembly located on the right side.

[0016] More preferably, a support frame is fixedly connected to the outer wall of the housing.

[0017] The present invention has the following advantages due to the adoption of the above technical solution:

[0018] This invention uses a screw conveyor to transport the clinker after initial grinding to a connecting pipe, and then through an extension pipe into the grinding assembly on the right. The grinding assembly on the right performs secondary grinding of the clinker, thus connecting the two grinding assemblies for fine grinding of the clinker particles. During the grinding process, a closing cylinder controls a sealing plate to close the right-side discharge pipe while opening the left-side discharge pipe, allowing the initially ground clinker particles to be discharged directly. The two grinding assemblies can then operate independently. Compared to existing technologies, this invention, through the coordination of the screw conveyor, the first discharge hopper, the opening and closing cylinder, the two discharge pipes, and the sealing plate, enables interconnection between the two grinding assemblies, achieving fine grinding of the clinker particles. Simultaneously, it allows for independent operation of the two grinding assemblies to meet different application requirements.

Detailed Implementation

[0028] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0029] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0030] like Figures 1-6 As shown, this utility model embodiment provides a combined grinding device, including two grinding components 301. The two grinding components 301 are connected by a connecting component 101. The two grinding components 301 can be connected end to end by the connecting component 101, thereby realizing secondary grinding of clinker particles.

[0031] The connecting component 101 includes a screw conveyor 11, a first hopper 12, an opening and closing cylinder 13, two feeding pipes 14, a closing plate 15, a connecting plate 16, an L-shaped mounting base 17, a plug-in groove 19, a connecting pipe 20, and an extension pipe 39.

[0032] One end of the connecting pipe 20 is installed at the discharge port of the screw conveyor 11, and the other end of the connecting pipe 20 is connected to the extension pipe 39. The extension pipe 39 is installed on the top of the grinding assembly 301 on the right side and is connected to the feed hopper 32 in the grinding assembly 301 on the right side. Thus, when the screw conveyor 11 is working, the clinker after the first grinding can be conveyed to the connecting pipe 20 and then flow into the grinding assembly 301 on the right side through the extension pipe 39 to achieve the secondary grinding of the clinker.

[0033] Two feed pipes 14 are symmetrically fixedly connected to the outer side wall of the first feed hopper 12. One feed pipe 14 is connected to the feed inlet of the screw conveyor 11. The clinker after the first grinding can be fed through the feed pipe 14. Since there are two feed pipes 14, the opening and closing of the feed pipes 14 can be adjusted according to the usage requirements.

[0034] When the left feed pipe 14 is closed and the right feed pipe 14 is open, the clinker after the first grinding enters the screw conveyor 11, and the screw conveyor 11 conveys the clinker to the right grinding assembly 301 for secondary grinding.

[0035] When the left feed pipe 14 is open and the right feed pipe 14 is closed, the clinker after the first grinding is discharged directly through the left feed pipe 14. Thus, the opening or closing of the two feed pipes 14 can be selected according to the particle size requirements.

[0036] The insertion slot 19 is formed on the inner side wall of the feed pipe 14. The sealing plate 15 is slidably connected to the inner side wall of the insertion slot 19. One side of the connecting plate 16 is fixedly connected to the sealing plate 15, and the other side of the connecting plate 16 is fixedly connected to the cylinder shaft of the opening and closing cylinder 13. The opening and closing cylinder 13 is installed on one side of the L-shaped mounting base 17, which is installed on the outer side wall of the first feed hopper 12. The opening and closing cylinder 13 drives the connecting plate 16 to move, and the connecting plate 16 drives the sealing plate 15 to slide in the insertion slot 19. When the cylinder shaft of the opening and closing cylinder 13 extends, the sealing plate 15 closes the feed pipe 14. When the cylinder shaft of the opening and closing cylinder 13 returns to its original position, the feed pipe 14 opens.

[0037] In one embodiment, two guide rods 18 are symmetrically fixedly connected to the side of the connecting plate 16 away from the closing plate 15. The guide rods 18 are slidably connected inside the L-shaped mounting base 17 and can play a guiding role so that the connecting plate 16 can move axially.

[0038] In one embodiment, the grinding assembly 301 includes a housing 31, a feed hopper 32, two geared motors 33, two grinding rollers 34, and two bearing seats 36;

[0039] Two grinding rollers 34 are symmetrically located inside the housing 31. The grinding rollers 34 are rotatably connected to the housing 31 through two bearing seats 36. The feed hopper 32 is installed on the top of the housing 31. Two geared motors 33 are symmetrically installed on the front surface of the housing 31. The output shaft of the geared motor 33 is fixedly connected to the roller shaft of the grinding roller 34. The grinding roller 34 is driven to rotate by the geared motor 33. Under the action of the two grinding rollers 34, the clinker particles can be ground.

[0040] In one embodiment, two grinding components 301 are arranged symmetrically on the left and right sides. The first hopper 12 is installed at the bottom of the grinding component 301 on the left side, and the second hopper 40 is installed at the bottom of the grinding component 301 on the right side. When the grinding component 301 on the left side is working, the ground clinker falls into the first hopper 12. When the grinding component 301 on the right side is working, the ground clinker falls into the second hopper 40.

[0041] In one embodiment, a support frame 38 is fixedly connected to the outer wall of the housing 31. The support frame 38 can enhance the stability of the grinding assembly 301. A bracket (not shown in the figure) is also provided on the outside of the screw conveyor 11 to enhance the stability of the screw conveyor 11 during operation.

[0042] In operation, this utility model works as follows: the grinding roller 34 is driven to rotate by the reduction motor 33, which can grind the clinker particles. The clinker particles are added into the feed hopper 32 on the left side, and the two grinding rollers 34 grind the clinker particles. The ground clinker falls into the first discharge hopper 12. The connecting plate 16 is moved by the opening and closing cylinder 13. The connecting plate 16 drives the closing plate 15 to slide in the insertion groove 19. The closing plate 15 closes the discharge pipe 14 on the left side and opens the discharge pipe 14 on the right side. The clinker after the first grinding enters the screw conveyor 11 through the discharge pipe 14 on the right side. The screw conveyor 11 can transport the clinker after the first grinding to the connecting pipe 20, and then flow into the grinding assembly 301 on the right side through the extension pipe 39. The grinding assembly 301 on the right side can realize the secondary grinding of the clinker, thus realizing the connection between the two grinding assemblies 301, which can perform fine grinding of clinker particles.

[0043] During the grinding process, the connecting plate 16 is moved by the opening and closing cylinder 13, and the connecting plate 16 drives the closing plate 15 to slide in the insertion groove 19. The closing plate 15 closes the feed pipe 14 on the right side and opens the feed pipe 14 on the left side. At this time, the clinker particles after the first grinding are directly discharged, and the two grinding components 301 can work independently.

[0044] Compared with the existing technology, this utility model, through the cooperation of the screw conveyor 11, the first hopper 12, the opening and closing cylinder 13, the two feeding pipes 14, the closing plate 15, etc., can realize the interconnection of the two grinding components 301, realize the fine grinding of clinker particles, and at the same time, it can control the two grinding components 301 to work independently according to the usage requirements.

[0045] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
