Description
Technical Field
[0001] This utility model relates to the field of boiler grate technology, specifically a novel grate. Background Technology
[0002] A grate is a commonly used piece of equipment in industrial production, typically consisting of a frame and grate bars. The grate bars are generally made of cast iron, and after assembly, necessary ventilation gaps are maintained between the bars to allow air to enter the fuel bed for combustion. Grate grates are widely used in metallurgy, chemical industry, petroleum, pharmaceuticals, food processing, and many other industries, serving as an important tool for high-temperature oxidation, combustion, roasting, drying, and heating processes. They not only reduce energy consumption and emissions but also improve the efficiency and quality of industrial production.
[0003] Traditional grate installation requires welding the grate to the water pipe. Welding can damage the surface of the water pipe, and thermal expansion and contraction can easily cause it to crack, resulting in water pipe damage and leakage.
[0004] Therefore, it is necessary to propose a solution for boiler grate devices to address the aforementioned problems. Utility Model Content

[0008] Furthermore, the stacking structure includes an arc-shaped block installed on the right side of the circular arc surface, the surface of the arc-shaped block being provided with an arc-shaped body, and the surface of the arc-shaped block being provided with a water pipe anti-slip surface.
[0009] Furthermore, the circular arc surface is manufactured by integral casting.
[0010] Furthermore, the plate can be spliced with the plate of another grate through an arc-shaped body.
[0011] Furthermore, grooves are provided on both sides of the plate.
[0012] Furthermore, the water pipe is located below the arc-shaped body and fits snugly against the lower part of the arc-shaped body.
[0013] Furthermore, the circular arc surface is at the same angle as the anti-slip surface of the water pipe.
[0014] Furthermore, a weight-reducing groove is provided between the circular arc surface and the arc-shaped body.
[0015] Compared with the prior art, the technical effects and advantages of this utility model are as follows: This utility model provides a new type of grate, the grate plate is made into an integral structure with a circular arc surface by casting. During installation, it can be directly placed on the water pipe. This utility model replaces the traditional welding method, which can effectively prevent water pipe damage and leakage. The installation is more convenient.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0027] Please see Figures 1 to 5 This utility model provides a technical solution:
[0028] A novel grate includes a plate body 1, on the surface of which a first air passage groove 2 is formed, and a circular arc surface body 3 is installed below the plate body 1. Overlapping structures 4 capable of fitting with the surface of a water pipe 6 are installed on both sides of the circular arc surface body 3.
[0029] In the specific implementation process, such as Figure 4 The stacking structure 4 shown includes an arc-shaped block 41 installed on the right side of the circular arc surface 3. An arc-shaped body 42 is provided on the surface of the arc-shaped block 41, and a water pipe anti-slip surface 43 is provided on the surface of the arc-shaped block 41.
[0030] It should be noted that the arc-shaped block 41 installed on the right side of the circular arc surface 3 has an arc-shaped body 42 on its surface and a water pipe anti-slip surface 43 on its surface. Through the water pipe mounting structure 4 on both sides of the circular arc surface 3, the water pipe 6 can be placed on the water pipe anti-slip surface 43 on the surface of the arc block 41.
[0031] In the specific implementation process, such as Figure 4 The circular arc surface 3 shown is made by integral casting.
[0032] It should be noted that the circular arc surface 3 is made by casting as a whole. This grate plate is made by casting to form an integral structure with a circular arc surface. During installation, it can be directly placed on the water pipe 6. The circular arc surface 3 is made of cast iron alloy steel.
[0033] In the specific implementation process, such as Figure 4 The plate 1 shown can be spliced with the plate 1 of another grate through the arc-shaped body 42.
[0034] It should be noted that the plate 1 can be spliced with another grate plate 1 through the arc-shaped body 42. When it is necessary to increase the number of grate plates, the arc-shaped block 41 and arc-shaped body 42 installed on the right side of the circular arc surface 3 can be spliced with another grate plate to make the two arc-shaped bodies fit together.
[0035] In the specific implementation process, such as Figure 6 The plate 1 shown has grooves 5 on both sides.
[0036] It should be noted that grooves 5 are provided on both sides of the plate 1. When two grate plates need to be spliced together, the grooves 5 on both sides of the plate 1 will form a new air passage with the other half of the groove, ensuring that the gas blows from the bottom up and has the function of air holes, so as to ensure uniform air distribution.
[0037] In the specific implementation process, such as Figure 6 The water pipe 6 shown is located below the arc-shaped body 42 and is fitted tightly to the lower part of the arc-shaped body 42.
[0038] It should be noted that the water pipe 6 is located below the arc-shaped body 42 and is fitted tightly to the lower part of the arc-shaped body 42.
[0039] In the specific implementation process, such as Figure 1 The circular arc surface 3 shown is at the same angle as the anti-slip surface 43 of the water pipe.
[0040] It should be noted that the circular arc surface 3 is at the same angle as the anti-slip surface 43 of the water pipe, and the arc block 41 is installed along the axial direction of the circular arc surface 3.
[0041] In the specific implementation process, such as Figure 1 A weight-reducing groove 7 is provided between the circular arc surface 3 and the arc-shaped body 42 shown.
[0042] It should be noted that a weight-reducing groove 7 is provided between the circular arc surface 3 and the arc-shaped body 42.
[0043] The working principle of this embodiment is as follows: In specific use, this grate plate 1 is an integral structure with a circular arc surface, which is made by casting. During installation, it can be directly placed on the water pipe. This utility model replaces the traditional welding method, which can effectively prevent water pipe damage and leakage. The installation is more convenient. When it is necessary to increase the number of grate plates 1, the arc-shaped block 41 and arc-shaped body 42 installed on the right side of the circular arc-shaped body 3 can be spliced with another grate plate to make the two arc-shaped bodies fit together. This device prevents the burning materials on the grate from easily coking, greatly reducing the degree of coking.
[0044] The remaining parts not described in this utility model are existing or known technologies.
[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
