Description

Technical Field

[0001] This utility model belongs to the field of boiler technology, and specifically relates to an energy-saving gas clamp boiler. Background Technology

[0002] Currently, Chinese utility model patent CN218238349U discloses an improved energy-saving gas clamp boiler. Although the front of the clamp boiler is equipped with an observation window, which can improve the convenience of observation, there are still other problems in use. For example, the heat insulation effect is poor, the boiler body is only a single layer, and the high temperature inside the burner after igniting the fuel will easily be conducted outward through the inner wall, resulting in heat loss, increasing the waste of gas energy, reducing the internal heating efficiency, and making it inconvenient to carry out internal maintenance. The boiler shell only has an opening at the top, and a top plate is installed at the top to prevent dust from entering. When the internal monitoring components malfunction, the top plate must be removed from the top first, then the furnace must be removed from the inside, and finally, hands can be reached in for maintenance, which increases the workload of personnel. Utility Model Content

[0003] The purpose of this utility model is to provide an energy-saving gas-fired boiler, which has the advantages of good heat insulation and easy internal maintenance.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an energy-saving gas-fired clamp boiler includes a shell, an inner frame welded inside the shell, a furnace bolted inside the inner frame, an inner furnace inside the furnace, a first rock wool layer filling the space between the shell and the inner frame, a refractory diatomaceous earth layer installed on the inner wall of the furnace, a burner bolted to one side of the shell, an inspection port on the front of the shell, a baffle placed on the front of the shell, a fixing frame and a limiting seat bolted to the front of the shell and the front of the baffle respectively, a connecting block inside the limiting seat, a limiting spring bolted between one side of the connecting block and the limiting seat through a spring fixing piece, and a limiting rod welded to the other side of the connecting block.

[0005] The above technical solution achieves good thermal insulation, reduces internal heat loss, saves energy and reduces gas consumption, improves heating efficiency, facilitates internal maintenance, is simple and labor-saving to operate, improves personnel work efficiency, and is highly flexible and practical.

[0006] The present invention is further configured such that a high-temperature resistant filter mud is coated between the top of the furnace and the inner furnace.

[0007] By adopting the above technical solution, the thermal conductivity and corrosion resistance of the inner furnace can be enhanced by setting high-temperature resistant filter mud, so that the inner furnace can still maintain structural stability under high temperature conditions.

[0008] The present invention is further configured such that both the shell and the inner frame are made of stainless steel.

[0009] The above technical solution results in a shell and inner frame with high strength, low density, and excellent corrosion resistance.

[0010] The present invention is further configured such that a second rock wool layer is adhered to the back of the baffle.

[0011] By adopting the above technical solution, the insulation effect inside can be further improved by setting a second layer of rock wool.

[0012] The present invention is further configured such that a fixing rod is welded to the front of the connecting block, a sliding groove is provided on the front of the limiting seat, and the other end of the fixing rod extends to the outside of the sliding groove.

[0013] The above technical solution allows for easy maneuverability by using a fixed rod and sliding groove to pull the connecting block outwards.

[0014] The present invention is further configured such that the inner diameter of the through groove at the top of the shell is larger than the inner diameter of the inner furnace.

[0015] The above technical solution can prevent the internal solution from being blocked when it is poured out, allowing the solution to be poured out smoothly.

[0016] The present invention is further configured such that the limiting spring is made of carbon spring steel.

[0017] Using the above technical solution, the limit spring has the characteristics of excellent mechanical properties, good resistance to spring reduction, low temperature resistance and corrosion resistance.

[0018] In summary, this utility model has the following beneficial effects: 1. By pouring the material into the inner furnace and starting the burner to heat the inner furnace, the heat of the fuel is initially intercepted by the refractory diatomaceous earth layer when it is heated in the furnace chamber and the inner furnace. The refractory diatomaceous earth layer reduces the outward transfer of internal heat, while the first rock wool layer between the shell and the inner frame forms a second layer of protection, reducing the transfer of external factors inward and internal heat outward. This achieves good heat insulation effect, reduces internal heat loss, saves energy and reduces gas consumption, and improves heating efficiency. 2. By grasping the two fixed rods on the fixed frame and pulling them inward simultaneously, the fixed rods will cause the connecting block to move into the limiting seat. When the connecting block moves, it will not only cause the limiting rod to separate from the limiting hole on the side of the fixed frame, but also compress the limiting spring to cause it to contract and deform. When the fixed rod is pulled to the bottom, the fixed frame will be pulled outward, and then personnel can put their hands in through the inspection port to facilitate internal maintenance. The operation is simple and labor-saving, improving personnel's work efficiency, flexibility and practicality. Attached Figure Description

[0021] The present invention will be further described in detail below with reference to the accompanying drawings.

[0022] Example 1: refer to Figure 1 , Figure 2 and Figure 3 An energy-saving gas-fired clamp boiler includes a shell 1, an inner frame 2 welded inside the shell 1, a furnace 3 bolted inside the inner frame 2, and an inner furnace 5 inside the furnace 3. A first rock wool layer 6 is filled between the interior of the shell 1 and the inner frame 2. A refractory diatomaceous earth layer 7 is installed on the inner wall of the furnace 3. A burner 8 is bolted to one side of the shell 1. By pouring materials into the inner furnace 5 and starting the burner 8 to heat the inner furnace 5, the heat is initially intercepted by the refractory diatomaceous earth layer 7 when the fuel is heated in the furnace 3 and the inner furnace 5. The refractory diatomaceous earth layer 7 reduces the outward transfer of internal heat, while the first rock wool layer 6 between the shell 1 and the inner frame 2 forms a second layer of protection, reducing the inward transfer of external factors and the outward transfer of internal heat. This achieves good heat insulation, reduces internal heat loss, saves energy, reduces gas consumption, and improves heating efficiency.

[0023] refer to Figure 2The top of the furnace 3 and the inner furnace 5 are coated with high-temperature resistant filter mud 16. The high-temperature resistant filter mud 16 can enhance the thermal conductivity and corrosion resistance of the inner furnace 5, so that the inner furnace 5 can maintain structural stability under high temperature conditions.

[0024] refer to Figure 1 , Figure 2 and Figure 3 Both the shell 1 and the inner frame 2 are made of stainless steel, and the shell 1 and the inner frame 2 have the characteristics of high strength, low density and excellent corrosion resistance.

[0025] refer to Figure 2 The inner diameter of the through groove at the top of the shell 1 is larger than the inner diameter of the inner furnace 5, which can prevent the internal solution from being blocked when it is poured out, and allow the solution to be poured out smoothly.

[0026] Brief description of the usage process: By pouring the material into the inner furnace 5 and starting the burner 8 to heat the inner furnace 5, the heat will be initially intercepted by the refractory diatomaceous earth layer 7 when the fuel is heated in the furnace 3 and the inner furnace 5. The refractory diatomaceous earth layer 7 will reduce the outward transfer of internal heat, while the first rock wool layer 6 between the shell 1 and the inner frame 2 will form a second layer of protection, reducing the transfer of external factors inward and internal heat outward.

[0027] Example 2: refer to Figure 1 , Figure 3 and Figure 4 An energy-saving gas-fired clamp boiler has an inspection port 9 on the front of the shell 1. A baffle 11 is placed on the front of the shell 1. A fixed frame 10 and a limiting seat 12 are respectively bolted to the front of the shell 1 and the front of the baffle 11. A connecting block 13 is provided inside the limiting seat 12. A limiting spring 14 is bolted between one side of the connecting block 13 and the limiting seat 12 through a spring fixing plate. A limiting rod 15 is welded to the other side of the connecting block 13. By grasping the two fixing rods 4 on the fixed frame 10 and pulling them inward simultaneously, the fixing rods 4 will drive the connecting block 13 to move inward into the limiting seat 12. When the connecting block 13 moves, it will not only cause the limiting rod 15 to separate from the limiting hole on the side of the fixed frame 10, but also compress the limiting spring 14 to cause it to contract and deform. When the fixing rods 4 are pulled to the bottom, the fixed frame 10 is pulled outward. Then, personnel can put their hands in through the inspection port 9 for easy internal maintenance. The operation is simple and labor-saving, improving the work efficiency of personnel and offering high flexibility and practicality.

[0028] refer to Figure 4 A second rock wool layer 17 is bonded to the back of the baffle 11. The second rock wool layer 17 can further improve the internal insulation effect.

[0029] refer to Figure 1 and Figure 4A fixing rod 4 is welded to the front of the connecting block 13, and a sliding groove 18 is provided on the front of the limiting seat 12. The other end of the fixing rod 4 extends to the outside of the sliding groove 18. With the setting of the fixing rod 4 and the sliding groove 18, it is easy for personnel to pull the connecting block 13 outward by hand.

[0030] refer to Figure 4 The limiting spring 14 is made of carbon spring steel and has excellent mechanical properties, good spring damping resistance, low temperature resistance and corrosion resistance.

[0031] Brief description of the usage process: By grasping the two fixing rods 4 on the fixing frame 10 and pulling them inward simultaneously, the fixing rods 4 will drive the connecting block 13 to move into the limiting seat 12 when pulled. When the connecting block 13 moves, it will not only cause the limiting rod 15 to separate from the limiting hole on the side of the fixing frame 10, but also compress the limiting spring 14 to cause it to contract and deform. When the fixing rods 4 are pulled to the bottom, the fixing frame 10 will be pulled outward, and then personnel can put their hands in through the inspection port 9.

[0032] It should be noted that parts have a lifespan and can be replaced during regular maintenance when they no longer meet performance requirements. Deterioration in performance due to prolonged use of parts is not a design defect of this application.
