Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to a temperature monitoring device for a steam curing kiln. Background Technology

[0002] An autoclaved aerated concrete (AAC) kiln is a type of equipment used to produce aerated concrete products.

[0003] Precast concrete components are subjected to high-temperature, high-pressure steam in an autoclave to accelerate their hardening process and improve the strength and durability of the final product. Autoclaves are widely used in the manufacturing of building materials, especially in the production of lightweight building materials such as aerated concrete blocks and panels.

[0004] Existing steam curing kilns typically use electric heating to heat their interiors. Since electric heating is relatively constant, the temperature inside the kiln can be indirectly controlled by adjusting the temperature of the electric heating elements to perform the steam curing operation.

[0005] However, slight temperature fluctuations may still occur during prolonged operation. Existing steam curing kilns have not addressed this temperature issue, ultimately resulting in poor stability during steam curing operations. Utility Model Content

[0006] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a temperature monitoring device for steam curing kilns that is easy to install and remove and has high stability.

[0007] The objective of this utility model can be achieved through the following technical solutions:

[0008] A temperature monitoring device for a steam curing kiln, the steam curing kiln comprising a kiln body with an internal cavity, characterized in that the monitoring device is installed in the kiln body and includes a connecting pipe, a locking nut, a pressure plate, and a temperature probe. The connecting pipe is tubular and passes through the kiln body, with its two ends extending outwards from the inner and outer sides of the kiln body, respectively. The pressure plate and the locking nut are both fitted onto the connecting pipe to form positioning units, with a positioning unit at each end of the connecting pipe. The locking nut is threadedly connected to the connecting pipe. Under the action of the locking nut, the pressure plate in one positioning unit abuts against the inner side of the kiln body, and the pressure plate in the other positioning unit abuts against the outer side of the kiln body. The pressure plate and the kiln body have a connection structure that allows them to be tightly connected. The temperature probe is fixedly connected inside the connecting pipe.

[0009] In the above-mentioned steam curing kiln temperature monitoring device, the inner side of the pressing plate is a contact surface one for contacting the side surface of the kiln body, and the outer side of the pressing plate is a contact surface two for contacting the locking nut surface. The above-mentioned connection structure is located on the inner side of the pressing plate.

[0010] In the above-mentioned steam curing kiln temperature monitoring device, the inner side of the pressing plate is a contact surface one for contacting the side surface of the kiln body, and the outer side of the pressing plate is a contact surface two for contacting the locking nut surface. The above-mentioned connection structure is located on the outer side of the pressing plate.

[0011] In the above-mentioned steam curing kiln temperature monitoring device, the connecting structure includes a plate-shaped positioning plate, the inner end of which is flush with the pressing plate, and the outer end of which protrudes from the side of the pressing plate.

[0012] In the aforementioned steam curing kiln temperature monitoring device, the positioning plate has a smooth bend transition from the inner end to the outer end.

[0013] In the above-mentioned steam curing kiln temperature monitoring device, there are several positioning plates, which are evenly distributed circumferentially on the inner side of the pressing plate.

[0014] In the above-mentioned steam curing kiln temperature monitoring device, the angle between the outer end of the positioning plate and the side plane of the pressing plate is 30-60 degrees.

[0015] In the above-mentioned steam curing kiln temperature monitoring device, one side of the outer end of the positioning plate is flush with the side of the pressing plate, and the other side of the outer end of the positioning plate protrudes from the other side of the pressing plate.

[0016] In the above-mentioned steam curing kiln temperature monitoring device, the thickness of the pressing plate is 1 / 5 to 1 / 3 of the thickness of the locking nut.

[0017] In the above-mentioned temperature monitoring device for steam curing kiln, the outer end of the temperature probe is the sensing end, and the size of the sensing end is larger than the inner diameter of the connecting pipe. The sensing end abuts against the end of the connecting pipe.

[0018] Compared with existing technologies, the temperature monitoring device for this steam curing kiln serves two functions due to the connecting pipe:

[0019] Firstly, after the connecting tube is connected to the temperature probe, the temperature probe can be stably fixed inside the connecting tube.

[0020] Secondly, the connecting pipe can be stably connected to the kiln body by pressing the plate and tightening the nut.

[0021] It can be seen that, with the help of the connecting pipe, the temperature probe can be stably connected to the kiln body.

[0022] Meanwhile, the locking nut is easy to disassemble, ultimately allowing the connecting pipe to be stably removed from the kiln body. Since the temperature probe is connected inside the connecting pipe, it is also stably connected to the kiln body. It can be seen that this device enables the temperature probe to be stably and easily attached and detached from the kiln body.

[0023] Meanwhile, since the pressing plates and locking nuts are both tightly attached to the kiln body, the entire device has a relatively compact structure and high practical value. Attached Figure Description

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0030] like Figure 1 and Figure 2 As shown, the steam curing kiln includes a kiln body 1 with an internal cavity.

[0031] The temperature monitoring device for this steam curing kiln is installed at the kiln body 1 and includes a connecting pipe 2, a locking nut 3, a pressure plate 4, and a temperature probe 5. The connecting pipe 2 is tubular and passes through the kiln body 1. The two ends of the connecting pipe 2 extend outward from the inner and outer sides of the kiln body 1, respectively. The pressure plate 4 and the locking nut 3 are both fitted onto the connecting pipe 2 to form positioning units. Each end of the connecting pipe 2 has a positioning unit. The locking nut 3 is threadedly connected to the connecting pipe 2. Under the action of the locking nut 3, the pressure plate 4 in one positioning unit abuts against the inner side of the kiln body 1, and the pressure plate 4 in the other positioning unit abuts against the outer side of the kiln body 1. The pressure plate 4 and the kiln body 1 have a connection structure that allows them to be tightly connected. The temperature probe is fixed inside the connecting pipe 2.

[0032] The connecting pipe 2 is installed on the kiln body 1, and the two ends of the connecting pipe 2 extend out of the inner and outer sides of the kiln body 1, respectively.

[0033] One of the positioning units is located inside the kiln body 1, and the other positioning unit is located outside the kiln body 1.

[0034] One of the positioning units' pressure plates 4 is pressed tightly between the inner side of the kiln body 1 and the locking nut 3, while the other positioning unit's pressure plate 4 is pressed tightly between the outer side of the kiln body 1 and the locking nut 3.

[0035] Since there is a connection structure between the pressing plate 4 and the kiln body 1, the connection structure can not only improve the connection stability between the pressing plate 4 and the kiln body 1, but also stabilize and eliminate the gap between the connecting pipe 2 and the kiln body 1.

[0036] Of course, the temperature probe 5 is fixed inside the connecting pipe 2, so the temperature probe 5 can stably monitor the actual temperature inside the steam curing kiln.

[0037] The inner side of the pressure plate 4 is a contact surface 4a for contacting the side surface of the kiln body 1, and the outer side of the pressure plate 4 is a contact surface 4b for contacting the surface of the locking nut 3. The connection structure is located on the inner side of the pressure plate 4. Alternatively, depending on the actual situation, it is also feasible to have the inner side of the pressure plate 4 as the contact surface 4a for contacting the side surface of the kiln body 1, and the outer side of the pressure plate 4 as the contact surface 4b for contacting the surface of the locking nut 3, with the connection structure located on the outer side of the pressure plate 4.

[0038] There is a gap between the connecting pipe 2 and the kiln body 1. However, the two sides of the pressing plate 4 are contact surface 4a and contact surface 4b, respectively. Therefore, the pressing plate 4 can stably connect to the kiln body 1 while also stably eliminating the gap between the connecting pipe 2 and the kiln body 1.

[0039] Regardless of whether the connection structure is located inside or outside the pressing plate 4, it can ensure that the connecting pipe 2 is stably connected to the kiln body 1.

[0040] The connection structure includes a sheet-shaped positioning piece 4c, the inner end of which is flush with the pressure plate 4, and the outer end of which protrudes from the side of the pressure plate 4.

[0041] The positioning piece 4c has a smooth bend transition from the inner end to the outer end.

[0042] When the product is semi-finished, the two sides of the positioning piece 4c are flush with the inner and outer sides of the pressing piece 4, respectively.

[0043] The inner end of the positioning piece 4c is bent to form an arc-shaped and smooth transition section. Since the outer end of the positioning piece 4c has been flipped, the outer end of the positioning piece 4c can stably protrude from the pressure plate 4.

[0044] The number of positioning pieces 4c is several, and the positioning pieces 4c are evenly distributed circumferentially on the inner side of the pressing plate 4.

[0045] Multiple circumferentially distributed positioning plates 4c can effectively improve the connection stability between the positioning plates 4c and the kiln body 1.

[0046] The angle between the outer end of the positioning piece 4c and the side plane of the pressure plate 4 is 30 degrees. Depending on the actual situation, it is also feasible for the angle between the outer end of the positioning piece 4c and the side plane of the pressure plate 4 to be 60 degrees.

[0047] This angle allows the outer end of the positioning piece 4c to protrude stably from the pressure piece 4.

[0048] One side of the outer end of the positioning piece 4c is flush with the side of the pressure plate 4, and the other side of the outer end of the positioning piece 4c protrudes from the other side of the pressure plate 4.

[0049] The outer end of the positioning piece 4c protrudes from the pressure piece 4, with one side facing the side wall of the kiln body 1, ensuring that the pressure piece 4 is properly embedded in the kiln body 1, thereby ensuring the connection stability between the connecting pipe 2 and the kiln body 1.

[0050] The thickness of the pressure plate 4 is 1 / 5 of the thickness of the locking nut 3. Depending on the actual situation, it is also feasible for the thickness of the pressure plate 4 to be 1 / 3 of the thickness of the locking nut 3.

[0051] The outer end of the temperature probe 5 is the sensing end 5aa, and the size of the sensing end 5a is larger than the inner diameter of the connecting pipe 2. The sensing end 5a abuts against the end of the connecting pipe 2.

[0052] This structure allows the sensing end 5a to be stably located at the end of the connecting tube 2.

[0053] The temperature monitoring device for this steam curing kiln serves two functions due to the connecting pipe:

[0054] Firstly, after the connecting tube is connected to the temperature probe, the temperature probe can be stably fixed inside the connecting tube.

[0055] Secondly, the connecting pipe can be stably connected to the kiln body by pressing the plate and tightening the nut.

[0056] It can be seen that, with the help of the connecting pipe, the temperature probe can be stably connected to the kiln body.

[0057] Meanwhile, the locking nut is easy to disassemble, ultimately allowing the connecting pipe to be stably removed from the kiln body. Since the temperature probe is connected inside the connecting pipe, it is also stably connected to the kiln body. It can be seen that this device enables the temperature probe to be stably and easily attached and detached from the kiln body.

[0058] Meanwhile, since the pressing plates and locking nuts are both tightly attached to the kiln body, the entire device has a relatively compact structure and high practical value.

[0059] The technical features of the above-described embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0060] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Any appropriate changes and variations made to the above embodiments within the scope of the essential spirit of the present utility model shall fall within the scope of protection claimed by the present utility model.
