[0028] Please refer to Figure 1 and Figure 2 , an embodiment of the present application provides a lance brick structure 100, including a lance brick main body 10 and an aggregation component 20. The lance brick main body 10 has a receiving cavity 11 and a first port 12 and a second port 13 that are communicated with the receiving cavity 11 and are oppositely arranged. The aggregation component 20 is disposed in the receiving cavity 11, and an injection channel 21 for injecting flames is formed inside the aggregation component 20. The inlet 22 of the injection channel 21 is communicated with the first port 12, and the outlet 23 is communicated with the second port 13.
[0029] It should be noted that the lance brick structure 100 refers to a structure that is connected to the kiln body of a tunnel kiln and provides flames into the kiln body to realize the firing of products in the kiln body. The lance brick main body 10, as the main part of the lance brick structure 100, can accommodate and install other components in the lance brick structure 100. A receiving cavity 11 is formed inside the lance brick main body 10, and a first port 12 and a second port 13 that are communicated with the receiving cavity 11 are respectively opened on the surfaces at opposite ends of the lance brick main body 10. In this way, the receiving cavity 11 can communicate with the external environment through the first port 12 and the second port 13.
[0030] Currently, the second port 13 of the lance brick main body 10 is usually communicated with the inside of the kiln body of the tunnel kiln, and the flames enter the inside of the kiln body from the first port 12 through the receiving cavity 11 and the second port 13. Then, the width of the kiln body of the tunnel kiln usually reaches 1.5 meters to 1.6 meters, and the volume of the receiving cavity 11 is relatively large. After the flames enter the receiving cavity 11, they will be dispersed, resulting in a short range of the flames. In this way, the flames are not gathered enough and the range is short, making the products in the kiln body heated unevenly, and there are phenomena of overburning or underburning of some products, affecting the firing quality of the products.
[0031] Based on this, an aggregation component 20 is disposed in the receiving cavity 11, and an injection channel 21 is formed inside the aggregation component 20. The inlet 22 of the injection channel 21 is communicated with the first port 12, and the outlet 23 is communicated with the second port 13. In this way, the flames enter the injection channel 21 from the inlet 22 and are ejected from the outlet 23 of the injection channel 21 into the inside of the kiln body to fire the products inside the kiln body.
[0032] Since the injection channel 21 has an effect of concentrating the flame, the flame has a relatively long range, improving the uniformity of the temperature in the kiln, making the products heat more evenly inside the kiln body, and thus improving the firing quality of the products.
[0033] In some embodiments, the concentrating member 20 is detachably disposed in the receiving cavity 11.
[0034] During use, when the flame is injected into the kiln body through the injection channel 21, the concentrating member 20 is directly impacted by the flame, and problems such as easy wear or cracking are likely to occur. Therefore, the concentrating member 20 is detachably disposed in the receiving cavity 11. When problems such as wear or cracking occur to the concentrating member 20, the concentrating member 20 can be replaced more conveniently, and the operation is simpler.
[0035] Furthermore, the inner diameter size of the injection channel 21 will directly affect the range of the flame. Based on this, in practical applications, the inner diameter of the injection channel 21 can also be flexibly adjusted according to the required range of the flame. That is, according to the required range, the injection channel 21 with a suitable inner diameter size is replaced, so that the effect of injecting the flame into the kiln body is better.
[0036] As Figure 3 shown, in some embodiments, the diameter D1 of the inlet 22 of the injection channel 21 is smaller than the diameter D2 of the outlet 23.
[0037] Specifically, the diameter of the inlet 22 of the injection channel 21 is set to be smaller than the diameter of its outlet 23, that is, the flame enters the inside of the injection channel 21 from a smaller diameter and then sprays out from a larger diameter. In this way, the effect of the flame spraying out of the injection channel 21 can be further improved, so that the flame can be more smoothly sprayed into the kiln body and the products inside the kiln body can be evenly fired.
[0038] In some embodiments, in a plane intersecting the penetrating direction of the injection channel 21, the inner diameter of the injection channel 21 gradually increases from the inlet 22 end to the outlet 23 end.
[0039] Specifically, the injection channel 21 can be set as a circular channel. In addition, in a plane perpendicular to the penetrating direction of the injection channel 21, that is, in the cross-section of the injection channel 21, the inner diameter of the injection channel 21 gradually increases from the inlet 22 end to the outlet 23 end.
[0040] That is to say, the injection channel 21 forms a frustum structure with a gradually increasing diameter from the inlet 22 to the outlet 23, enabling the flame to be more smoothly sprayed into the kiln body along the injection channel 21 and forming a more uniform firing of the products inside the kiln body.
[0041] In some embodiments, the focusing member 20 has an incident end face 24 and an exit end face 25 which are oppositely arranged. The inlet 22 is formed on the incident end face 24, and the outlet 23 is formed on the exit end face 25. Among them, the contour of the incident end face 24 matches the shape of the first port 12; and / or, the contour of the exit end face 25 matches the shape of the second port 13.
[0042] Specifically, when the focusing member 20 is arranged in the accommodation cavity 11, the incident end face 24 is arranged close to the first port 12 of the accommodation cavity 11, and the incident end face 24 is arranged parallel to the surface where the first port 12 is located. The exit end face 25 is arranged close to the second port 13 of the accommodation cavity 11, and the exit end face 25 is arranged parallel to the surface where the second port 13 is located.
[0043] Furthermore, the inlet 22 of the injection channel 21 is formed on the incident end face 24, and the outlet 23 is formed on the exit end face 25. Among them, the outer contour of the incident end face 24 matches the shape of the first port 12, that is, when the shape of the first port 12 is set as a rectangle, the outer contour of the incident end face 24 is set as a rectangle matching the first port 12. In this way, the incident end face 24 can be better received inside the first port 12.
[0044] Similarly, the outer contour of the exit end face 25 matches the shape of the second port 13, that is, when the shape of the second port 13 is set as a rectangle, the outer contour of the exit end face 25 is set as a rectangle matching the second port 13. In this way, the incident end face 24 can be better received inside the second port 13.
[0045] In addition, when the focusing member 20 is detachably arranged in the accommodation cavity 11, by setting the contour of the incident end face 24 to match the shape of the first port 12 and setting the contour of the exit end face 25 to match the shape of the second port 13, the focusing member 20 can be more smoothly removed from the accommodation cavity 11, which is convenient for operation.
[0046] In some embodiments, the area of the incident end face 24 is not greater than the opening area of the first port 12; and / or, the area of the exit end face 25 is not greater than the opening area of the second port 13.
[0047] Specifically, the area of the incident end face 24 is not greater than the opening area of the first port 12, so that the incident end face 24 can be smoothly received inside the first port 12. Similarly, the area of the exit end face 25 is not greater than the opening area of the second port 13, so that the exit end face 25 can be smoothly received inside the second port 13.
[0048] In this way, the gun brick body 10 can form better protection around the aggregation component 20, and it is better that the aggregation component 20 can also be smoothly removed from the accommodation cavity 11, which is convenient for operation.
[0049] In some embodiments, the gun brick structure 100 further includes a burner gun 30, and the burner gun 30 is communicated with the inlet 22 of the injection channel 21 for injecting flame into the injection channel 21.
[0050] Specifically, the outlet of the burner gun 30 is communicated with the inlet 22 of the injection channel 21. The burner gun 30 can form a flame and spray the flame toward the inlet 22 of the injection channel 21, so that the flame sequentially passes through the inlet 22 of the injection channel 21, the injection channel 21, and the outlet 23 of the injection channel 21, and finally is sprayed into the interior of the kiln body of the tunnel kiln to uniformly fire the products inside the kiln body.
[0051] In some embodiments, the gun brick structure 100 further includes a conveying pipeline 40 communicated with the burner gun 30, and the conveying pipeline 40 is used for conveying combustible gas to the burner gun 30.
[0052] Specifically, one end of the conveying pipeline 40 can be communicated with an external gas supply device, and the other end is communicated with the burner gun 30. In this way, the conveying pipeline 40 can convey external combustible gas, such as natural gas, etc., into the burner gun 30, then form a flame inside the burner gun 30, and be sprayed into the interior of the kiln body through the injection channel 21.
[0053] In some embodiments, the gun brick structure 100 further includes a combustion air duct 50, and the combustion air duct 50 is communicated with the burner gun 30. The combustion air duct 50 can supply combustion air to the inside of the burner gun 30, so that a flame can be smoothly formed inside the burner gun 30 and the flame can be smoothly sprayed into the injection channel 21 and the interior of the kiln body.
[0054] Based on the same concept as the above gun brick structure 100, the present application also provides a tunnel kiln, including a kiln body and the gun brick structure 100 as described above, and the outlet 23 of the injection channel 21 is arranged toward the interior of the kiln body.
[0055] Specifically, the kiln body can include one cavity or multiple cavities. When multiple cavities are provided, the cavities are sequentially arranged along the direction of flame spraying and are communicated with each other, so that the flame can be sequentially sprayed into each cavity to fire the products in each cavity.
[0056] According to one or more embodiments, when in use, the present application first supplies natural gas to the inside of the burner gun 30 through the conveying pipeline 40, and supplies combustion-supporting air to the inside of the burner gun 30 through the combustion-supporting air duct 50, so that a flame is successfully formed inside the burner gun 30, and the flame is ejected from the inlet 22 of the ejection channel 21 into the ejection channel 21. The flame moves along the ejection channel 21 and finally ejects from the outlet 23 of the ejection channel 21 into the interior of the kiln body of the tunnel kiln to fire the products inside the kiln body.
[0057] Among them, since the flame converges inside the ejection channel 21, the flame has a greater range and can fire the products at different positions inside the kiln body more evenly, thereby improving the firing quality of the products.
[0058] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.
[0059] The above-described embodiments only represent several implementation manners of the present application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
