Description

Technical Field

[0001] The utility model belongs to the technical field of grate coolers, and in particular relates to a grate cooler roller crusher with a new lining plate. Background Art

[0002] With the rapid development of China's cement industry, the grate cooler clinker cooling system plays a vital role in the cement production process. However, in actual operation, the crushing efficiency of the clinker cooling system is low, which seriously affects the stability and production capacity of the cement production line. Specifically, high-temperature clinker is prone to agglomeration inside the grate cooler, which affects the clinker cooling effect. In addition, since the grate cooler crusher is a hammer crusher with a short service life of the hammer head, large pieces of clinker cannot be crushed in time after entering the crusher, causing the crusher to trip and stop.

[0003] Therefore, a grate cooler roll crusher with a novel liner is provided. Utility Model Content

[0004] In view of the problems raised by the above background technology, the purpose of the utility model is to provide a grate cooler roller crusher with a new liner.

[0005] In order to achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0006] A grate cooler roller crusher with a novel liner comprises a crushing box, wherein the upper end of the crushing box is provided with a feed inlet, and the lower end of the crushing box is provided with a discharge outlet;

[0007] The inner cavity of the crushing box is arranged with two main crushing rollers and two secondary crushing rollers, the main crushing rollers are symmetrically arranged below the feed port, the secondary crushing rollers are symmetrically arranged below the main crushing rollers and receive the clinker dropped from the main crushing rollers, and the crushing spacing between the main crushing rollers is greater than the crushing spacing between the secondary crushing rollers;

[0008] A material guide lining is arranged at the discharge port, and the material guide lining is in an arched arc shape. Beveled surfaces are arranged on both sides of the material guide lining. The beveled surfaces of the material guide lining expand and disperse the landing points of the clinker. The top view shape of the material guide lining is a parallelogram, and the beveled surfaces constitute the hypotenuse of the parallelogram.

[0009] It is further defined that an inspection port is provided on the side of the crushing box, the inspection port is connected to an inspection plate, the inspection plate is provided with a glass observation window and a handle. With such a structural design, the inspection port is used for inspection, the glass observation window can be used for observation without opening the inspection plate, and the handle is used for holding and applying force.

[0010] It is further defined that two material collecting plates are symmetrically arranged in the inner cavity of the crushing box, and the material collecting plates are provided with a material collecting slope and a skirt located at the lower edge of the material collecting slope. The two material collecting plates are arranged in a positional relationship of far at the top and close at the bottom according to the spacing of the material collecting slopes, and the material guide lining plate is located between the skirts of the two material collecting plates. With such a structural design, the material collecting slopes of the two material collecting plates together form a converging opening which is larger at the top and smaller at the bottom, which plays a converging role, and the skirt is used to prevent the clinker from spilling from the side of the material guide lining plate.

[0011] It is further defined that the material collecting slope of the material collecting plate is provided with spike-shaped crushing nails. With such a structural design, the crushing nails help to crush the clinker ejected onto the material collecting slope, thereby improving the crushing effect.

[0012] It is further defined that the surface of the material guide lining is provided with a plurality of parallel dividing strips along the length direction. With such a structural design, the dividing strips are used to forcibly separate the space, form a material channel, and regulate the clinker falling position.

[0013] The beneficial effects of the utility model are as follows: the agglomerated clinker is crushed by replacing the hammer head with a crushing roller, and the agglomerated clinker is crushed under the pressure of the two main crushing rollers and the secondary crushing roller, which has a better effect and can effectively disperse the landing point of the clinker, so that the clinker is dispersed and spread out, avoiding the accumulation of clinker and the inability to effectively contact with the cold air.

[0028] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0029] like Figure 1-6 As shown, a grate cooler roller crusher with a novel liner of the utility model comprises a crushing box 1, a feed port 11 is provided at the upper end of the crushing box 1, and a discharge port 12 is provided at the lower end of the crushing box 1;

[0030] Two main crushing rollers 3 and two secondary crushing rollers 4 are arranged in the inner cavity of the crushing box 1. The main crushing rollers 3 are symmetrically arranged below the feed port 11. The secondary crushing rollers 4 are symmetrically arranged below the main crushing rollers 3 and receive the clinker dropped by the main crushing rollers 3. The crushing spacing between the main crushing rollers 3 is greater than the crushing spacing between the secondary crushing rollers 4.

[0031] A material guide lining 6 is provided at the discharge port 12. The material guide lining 6 is in an arched arc shape. Beveled surfaces 61 are provided on both sides of the material guide lining 6. The beveled surfaces 61 of the material guide lining 6 expand and disperse the landing points of the clinker. The top view shape of the material guide lining 6 is a parallelogram, and the beveled surfaces 61 constitute the hypotenuse of the parallelogram.

[0032] In this embodiment:

[0033] The two main crushing rollers 3 rotate in opposite directions, and the two secondary crushing rollers 4 also rotate in opposite directions. The main crushing rollers 3 and the secondary crushing rollers 4 are driven by a motor in the form of belt transmission;

[0034] The clinker is fed into the crushing box 1 through the feed port 11. When the agglomerated part passes through the gap between the two main crushing rollers 3, it is crushed into small pieces under the pressure of the two main crushing rollers 3. These small pieces of clinker fall between the two secondary crushing rollers 4. Since the crushing distance between the secondary crushing rollers 4 is smaller than the crushing distance between the main crushing rollers 3, the clinker will be further crushed. After the clinker is crushed, the contact area with the cold air can be increased, thereby improving the cooling efficiency.

[0035] The crushed clinker falls on the guide lining plate 6. The function of the guide lining plate 6 is to expand and disperse the clinker's landing point to prevent the clinker from piling up at the same landing point and being unable to disperse. If the clinker is piled up, the cooling effect of the grate cooler will be poor, because the clinker cannot be spread out and forms a larger contact area with the cold air.

[0036] Usually, clinker is fed into between the main crushing rollers 3 from a certain position, and is not fed uniformly along the length direction of the main crushing rollers 3. Therefore, this causes the clinker to accumulate at a certain place for crushing and outflow, and the outflowing clinker is also accumulated together and cannot be spread out to form a larger contact area with the cold air. In the utility model, the material guide lining 6 is an arched arc. After the clinker falls on the top of the material guide lining 6 at a fixed point, it slides down along both sides. Beveled surfaces 61 are provided on both sides of the material guide lining 6. On the beveled surfaces 61, the distances between a single point and the center line of the material guide lining 6 are different. Therefore, the corresponding landing points are different. The clinker slides out along the beveled surfaces 61, and the clinker can fall from different points and be dispersed in a larger range, avoiding the accumulation of clinker at a certain point. In addition, the clinker slides down along both sides and is dispersed to both sides. It has two sliding directions, which further avoids accumulation.

[0037] Preferably, an inspection port 13 is provided on the side of the crushing box 1, and the inspection port 13 is connected to the inspection panel 2, and the inspection panel 2 is provided with a glass observation window 22 and a handle 21. With this structural design, the inspection port 13 is used for inspection, the glass observation window 22 can be used for observation without opening the inspection panel 2, and the handle 21 is used for holding and applying force. In fact, other inspection structures can also be considered according to specific circumstances.

[0038] Preferably, two material collecting plates 5 are symmetrically arranged in the inner cavity of the crushing box 1. The material collecting plates 5 are provided with a material collecting slope 51 and a skirt 52 located at the lower edge of the material collecting slope 51. The two material collecting plates 5 are arranged in a positional relationship of far at the top and close at the bottom according to the spacing of the material collecting slope 51. The material guide lining plate 6 is located between the skirts 52 of the two material collecting plates 5. With such a structural design, the material collecting slopes 51 of the two material collecting plates 5 together form a converging opening that is larger at the top and smaller at the bottom, which plays a role of converging. The skirt 52 is used to prevent the clinker from spilling from the side of the material guide lining plate 6. In fact, other material collecting structures can also be considered according to specific circumstances.

[0039] Preferably, the material collecting slope 51 of the material collecting plate 5 is provided with spike-shaped crushing nails 53. With such a structural design, the crushing nails 53 help to crush the clinker ejected onto the material collecting slope 51, thereby improving the crushing effect. In fact, other auxiliary crushing structures can also be considered according to specific circumstances.

[0040] Preferably, the surface of the material guide liner 6 is provided with a plurality of parallel dividing strips 62 along the length direction. With such a structural design, the dividing strips 62 are used to forcibly separate the space, form a material channel, and regulate the clinker falling position. In fact, other conveying structures can also be considered according to specific circumstances.

[0041] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
