Description

Technical Field

[0001] The present application relates to the technical field of heating devices, and in particular to a fire-blocking assembly and a heating device. Background Art

[0002] High-temperature furnaces are typically equipped with sensors to monitor parameters such as the furnace temperature. These sensors are susceptible to damage in high-temperature environments and require regular replacement. The furnace body features a furnace opening corresponding to the sensor, and a removable flame shield is installed at the opening to facilitate replacement.

[0003] The external movable fire damper disclosed in the Chinese patent with publication number CN208967878U includes a fire damper assembly and an oven main body assembly. The fire damper assembly includes a fire damper, a rivet nut and a fire dividing plate. The fire dividing plate is installed on the inner side wall of the top of the fire damper. An M rivet nut is provided at one end of the fire damper, and a fire damper handle is inserted into the M rivet nut, so that the fire damper handle drives the fire damper to move; the fire damper is installed on two fire damper sliding rails, and the two fire damper sliding rails are connected to the furnace body by fixing bolts, so that the fire damper sliding rails can be fixed in the furnace body.

[0004] When the furnace mouth operating space is limited, it is often necessary to dismantle the fire baffle as a whole to avoid interference. Figure 9 As shown, a conventional fire baffle 5 has bolt holes 51 at its four corners. These holes are aligned with pre-installed studs on the furnace body, fully inserted into the bolt holes 51, and then tightened with nuts to seal the furnace opening. However, due to the high temperature of the furnace body and limited operating space, installation of the fire baffle 5 requires repeated alignment of the holes, making the process difficult and labor-intensive. Utility Model Content

[0005] In view of this, the present application provides a fire stop assembly and a heating device to solve the problem that the fire stop plate needs to be repeatedly aligned with the hole position during installation, which makes the operation difficult.

[0006] In a first aspect, an embodiment of the present application provides a firestop assembly, comprising:

[0007] A support plate is fixed to the furnace body and located at the lower edge of the furnace opening, wherein the side of the support plate away from the furnace body is higher than the side close to the furnace body to form a stopper;

[0008] The baffle is suitable for blocking the furnace opening. The baffle has a clamping portion that is clamped with the stopper portion, and an open notch formed by a local corner cutout of the baffle. The open notch matches the position of the screw on the furnace body.

[0009] When the baffle is in the installed state, the open slot surrounds a local area of ​​the screw rod, and the screw rod is connected to the nut to limit the baffle from falling out toward the side away from the furnace body.

[0010] In some embodiments, the open notch is formed at a top corner of the baffle away from the clamping portion.

[0011] In some embodiments, the baffle is recessed relative to the surface of the baffle in an area surrounding the open slot to form a step portion, which is used to accommodate the nut.

[0012] In some embodiments, the number of the open slots is two, the two open slots are respectively located at two vertex corners of the baffle, and the opening directions of the two open slots are opposite.

[0013] In some embodiments, the support plate is configured as an elongated strip, and an extension direction of the support plate is flush with a lower edge of the furnace opening.

[0014] In some embodiments, the support plate is fixedly connected to the furnace body via a support plate fixing member.

[0015] In some embodiments, the support plate is further connected to a fastening member, which passes through the stop portion and abuts against the clamping portion.

[0016] In some embodiments, the clamping portion corresponds to the position of the abutting member and is provided with a clamping groove along the insertion direction;

[0017] The edge of the clamping groove is located at the clamping portion and is partially enlarged to form a guide portion.

[0018] In some embodiments, the retaining member and the support plate are connected via a spring, so that when the clamping portion is installed into the stop portion, the retaining member is elastically pressed.

[0019] In a second aspect, the present application further provides a heating device, comprising:

[0020] A furnace body, wherein the furnace body is provided with a furnace opening;

[0021] As for the firestop assembly mentioned above, the firestop assembly can be detachably mounted on the furnace body to block or open the furnace opening.

[0022] Through the above technical solution, the firestop assembly provided by this application has the following beneficial effects:

[0023] 1. The fire baffle assembly provided in the embodiments of the present application is used to block the furnace opening opened on the furnace body. By fixing a support plate at the lower edge of the furnace body at the furnace opening, the support plate can support the lower edge of the baffle, making it convenient to quickly install the baffle on the support plate without repeatedly aligning the hole position, thereby reducing the difficulty of the operation. At the same time, by making the side of the support plate away from the furnace body higher than the side close to the furnace body to form a stop portion, the clamping portion formed at the lower edge of the baffle is engaged with the stop portion, thereby limiting the lower edge of the baffle. An open notch is formed in the local corner of the baffle, so that the open notch can be quickly assembled with the screw on the furnace body. Compared with the form of a bolt hole, the open notch has a larger open area, so the open notch can be quickly aligned with the screw, without repeatedly aligning the hole position, thereby reducing the difficulty of the operation.

[0024] 2. By locating the two open slots at the two top corners of the baffle, and with the opening directions of the two open slots in opposite directions, multi-point positioning of the baffle can be achieved. By cooperating with the support plate, the baffle can be firmly fixed on the furnace body to avoid deflection or dislocation.

[0025] 3. By making the extension direction of the support plate flush with the lower edge of the furnace mouth, it can be ensured that after the baffle is assembled with the support plate, the baffle can be automatically aligned with the lower edge of the furnace mouth without repeatedly adjusting the position, so that the support plate plays a role of pre-positioning.

[0026] 4. The retaining member can be pressed against the clamping portion, thereby ensuring the fit between the baffle and the furnace body and ensuring a tight installation of the baffle. The retaining member and the support plate are connected via a spring, so that when the clamping portion is installed into the stop portion, the retaining member elastically presses against it. This eliminates the need for repeated disassembly of the retaining member. When installing the baffle, the retaining member is compressed and retracted into the support plate, and the elastic force of the spring holds the baffle in place, making operation more convenient and eliminating the need for repeated disassembly and assembly of the retaining member.

[0027] 5. By providing a clamping groove on the clamping part, it is possible to ensure that the clamping member and the clamping groove are clamped tightly, ensuring the accurate installation position of the baffle. In addition, by providing a guide part on the clamping groove, the guide part and the clamping member cooperate to play a guiding role, which can reduce the difficulty of assembly and improve assembly efficiency.

[0050] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0051] The following combination Figures 1 to 8 , describing the embodiments of the present application.

[0052] According to an embodiment of the present application, on the one hand, a firestop assembly is provided, comprising:

[0053] The support plate 3 is fixed to the furnace body 1 and is located at the lower edge of the furnace opening 11. The side of the support plate 3 away from the furnace body 1 is higher than the side close to the furnace body 1 to form a stopper 33.

[0054] The baffle 2 is adapted to seal the furnace opening 11. The baffle 2 has a clamping portion 21 that is clamped with the stopper 33, and an open notch 22 formed by a local notch of the baffle 2. The open notch 22 matches the position of the screw 4 on the furnace body 1.

[0055] When the baffle 2 is in the installed state, the open slot 22 surrounds a local area of ​​the screw 4 , and the screw 4 is connected to the nut 41 to limit the baffle 2 from falling out toward the side away from the furnace body 1 .

[0056] The fire-blocking assembly provided in the embodiment of the present application is used to block the furnace opening 11 opened on the furnace body 1. By fixing a support plate 3 on the lower edge of the furnace body 1 located at the furnace opening 11, the support plate 3 can support the lower edge of the baffle 2, making it convenient to quickly install the baffle 2 on the support plate 3 without repeatedly aligning the hole position, thereby reducing the difficulty of the operation.

[0057] At the same time, by making the side of the support plate 3 away from the furnace body 1 higher than the side close to the furnace body 1 to form a stop portion 33, the clamping portion 21 formed on the lower edge of the baffle 2 is clamped with the stop portion 33, thereby limiting the lower edge of the baffle 2.

[0058] An open slot 22 is formed at a local corner of the baffle 2, so that the open slot 22 can be quickly assembled with the screw 4 on the furnace body 1. Compared with the bolt hole, the open slot 22 has a larger open area, so the open slot 22 and the screw 4 can be quickly aligned without repeatedly aligning the hole position, reducing the difficulty of the operation.

[0059] After the open notch 22 is aligned with the screw 4 , the baffle 2 can be limited by tightening the nut 41 onto the screw 4 , thereby achieving assembly of the baffle 2 and the furnace body 1 .

[0060] During the specific installation process, by slightly tilting the baffle 2, the lower edge of the baffle 2 is inserted into the stop portion 33, and the upper edge of the baffle 2 is straightened. By sliding the baffle 2 left and right, the open slot 22 can be quickly and accurately aligned with the screw 4 on the furnace body 1, so that the baffle 2 and the furnace body 1 are fitted together, ensuring that the baffle 2 accurately covers the furnace mouth 11, and then the nut 41 is tightened on the screw 4 to complete the assembly.

[0061] The invention solves the problem of difficult installation of traditional fire baffles, reduces the difficulty of operation, saves installation and maintenance time, and improves production efficiency. It enables workers to quickly complete the disassembly and assembly of the baffle 2 in a high temperature environment and under limited operating space.

[0062] The baffle 2 is also provided with an observation hole 24 for observing the working conditions of the components inside the furnace body 1. The observation hole 24 is sealed by a high temperature resistant transparent material.

[0063] In some embodiments, combined Figure 2 As shown, the open notch 22 is formed at a top corner of the baffle 2 away from the clamping portion 21 .

[0064] In some embodiments, combined Figure 2 As shown, there are two open slots 22 , which are respectively located at two vertex corners of the baffle 2 , and the opening directions of the two open slots 22 are opposite.

[0065] By locating the two open slots 22 at the two top corners of the baffle 2, and with the opening directions of the two open slots 22 being opposite, multi-point positioning of the baffle 2 can be achieved. By cooperating with the support plate 3, the baffle 2 can be firmly fixed on the furnace body 1 to avoid deflection or dislocation.

[0066] In some embodiments, combined Figure 2 As shown, the baffle 2 has a step portion 23 formed in a region surrounding the open slot 22 , which is recessed relative to the surface of the baffle 2 . The step portion 23 is used to accommodate the nut 41 .

[0067] By providing the step portion 23 , the nut 41 can be located in the step portion 23 after being tightened onto the screw rod 4 , thereby preventing the nut 41 from protruding too much and preventing the nut 41 from loosening due to accidental contact.

[0068] In some embodiments, combined Figure 2 、 Figure 4 As shown, the support plate 3 is constructed in a long strip shape, and the extension direction of the support plate 3 is flush with the lower edge of the furnace opening 11 .

[0069] By making the extension direction of the support plate 3 flush with the lower edge of the furnace mouth 11, it can be ensured that after the baffle 2 is assembled with the support plate 3, the baffle 2 can be automatically aligned with the lower edge of the furnace mouth 11 without the need for repeated position adjustment, so that the support plate 3 plays a role of pre-positioning.

[0070] In some embodiments, combined Figure 1 、 Figure 5 As shown, the support plate 3 is fixedly connected to the furnace body 1 via a support plate fixing member 31 .

[0071] The support plate fixing member 31 can be specifically a bolt. By fixing the support plate 3 to the furnace body 1 via the support plate fixing member 31, the support plate 3 does not need to be removed each time the baffle 2 is removed, and the support plate 3 is always kept in a fixed state.

[0072] In some embodiments, combined Figure 1 、 Figure 4 、 Figure 6 As shown, the support plate 3 is further connected to a fastening member 32 , which passes through the stopper 33 and abuts against the clamping portion 21 .

[0073] The pressing member 32 can press against the clamping portion 21 , thereby ensuring the fit between the baffle 2 and the furnace body 1 and ensuring that the baffle 2 is tightly installed.

[0074] The retaining member 32 may be a screw structure, and after the baffle 2 and the support plate 3 are assembled, the retaining member 32 is then independently installed.

[0075] As a variation, in some embodiments, the retaining member 32 is connected to the support plate 3 via a spring, so that when the clamping portion 21 is installed into the stop portion 33, the retaining member 32 elastically presses against it. This eliminates the need for repeated disassembly of the retaining member 32. When the baffle 2 is installed, the retaining member 32 is compressed and retracted into the support plate 3, and the elastic force of the spring presses against the baffle 2, making operation more convenient and eliminating the need for repeated disassembly and assembly of the retaining member 32.

[0076] In some embodiments, combined Figure 7 As shown, the clamping portion 21 corresponds to the position of the abutting member 32 and is provided with a clamping groove 211 along the insertion direction;

[0077] The edge of the clamping groove 211 located at the clamping portion 21 is partially enlarged to form a guide portion 212 .

[0078] By providing the clamping groove 211 on the clamping portion 21 , it is possible to ensure that the retaining member 32 is clamped to the clamping groove 211 , thereby ensuring that the baffle 2 is accurately installed.

[0079] Furthermore, by providing the guide portion 212 on the engaging groove 211 , the guide portion 212 cooperates with the abutting member 32 to play a guiding role, thereby reducing the difficulty of assembly and improving the assembly efficiency.

[0080] According to an embodiment of the present application, on the other hand, a heating device is provided, including:

[0081] The furnace body 1 is provided with a furnace opening 11;

[0082] As for the firestop assembly mentioned above, the firestop assembly can be detachably mounted on the furnace body 1 to block or open the furnace opening 11 .

[0083] The heating equipment provided in the embodiment of the present application provides a fire damper assembly to shield the furnace opening 11 opened on the furnace body 1. By fixing a support plate 3 at the lower edge of the furnace body 1 at the furnace opening 11, the support plate 3 can support the lower edge of the baffle 2, making it convenient to quickly install the baffle 2 on the support plate 3 without repeatedly aligning the hole positions, thereby reducing the difficulty of operation. By making the side of the support plate 3 away from the furnace body 1 higher than the side close to the furnace body 1 to form a stopper 33, the clamping portion 21 formed on the lower edge of the baffle 2 is clamped with the stopper 33, thereby limiting the lower edge of the baffle 2. This solves the problem of difficult installation of traditional fire dampers, reduces the difficulty of operation, saves installation and maintenance time, and improves production efficiency. It enables staff to quickly complete the disassembly and assembly of the baffle 2 in a high temperature environment and limited operating space.
