Description

Technical Field

[0001] The utility model relates to the technical field of heating structures, and particularly relates to a heating mechanism for an extruder. Background Technique

[0002] When puffed vegetables and fruits, first place the vegetables and fruits in the puffing tank, and then generate high-temperature steam through a steam generator to heat the vegetables and fruits in the puffing tank. Subsequently, use a high-pressure pump to pressurize the puffing tank. After maintaining high pressure for a period of time, quickly open the pressure relief valve to evacuate the air, so that the air pressure in the drying and puffing tank drops instantaneously, and the internal moisture of the material evaporates instantaneously, causing the internal tissue structure of the fruits and vegetables to expand rapidly, forming a honeycomb structure. Subsequently, after the material enters the vacuum drying stage, after a period of vacuum drying, when the moisture content drops to the required safe moisture content, stop heating. The refrigerating machine supplies cooling water to the interlayer until the temperature in the puffing tank reaches room temperature and then returns to the normal pressure state, thus completing the puffing of fruits and vegetables; and after use, the equipment needs to be maintained to ensure the normal operation of the machine. When maintaining the steam generator used for heating the puffing tank, it is necessary to remove and install the burner on one side. When installing the burner, it is necessary to align the flange on the burner with the flange on the steam generator, and then fix the positions of the two flanges through bolts. When the burner or the steam generator shakes when the bolts are tightened, the hole positions on the two flanges will deviate, resulting in the need for repeated alignment.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] The utility model provides Figures 1-4 The heating mechanism for the puffing machine shown in the figure comprises an puffing tank 1, a steam generator 2 is arranged on one side of the puffing tank 1, a burner 3 is arranged on the front side of the steam generator 2, a first connecting flange 4 is sleeved on the back side of the burner 3, a second connecting flange 5 is arranged on the front side of the steam generator 2, a limiting component 6 is arranged at the connection between the first connecting flange 4 and the second connecting flange 5, the limiting component 6 comprises limiting grooves 601 symmetrically arranged on both sides of the first connecting flange 4, limiting blocks 602 are inserted and connected inside the limiting grooves 601, a baffle 603 for limiting the movement of the first connecting flange 4 is arranged on the front side of the first connecting flange 4, a moving component 7 for moving the position of the limiting block 602 is arranged on one side of the limiting block 602, and the baffle 603 is fixedly connected to the front side of the limiting block 602.

[0020] It should be noted that a vacuum tank, an air compressor and a steam generator 2 are arranged at the air inlet end of the expanding tank 1, and a water pump is arranged at the water inlet end thereof, which is consistent with the working principle of a vacuum pressure difference drying and expanding device disclosed in patent announcement number CN214148567U when in use. The steam generator 2 and the burner 3 are fuel oil and gas steam generators of model DN-100KG; the limit block 602 is matched with the limit groove 601, and the baffle 603 is arranged with a cross section larger than the cross section of the limit groove 601. When in use, the limit block 602 is inserted into the interior of the limit groove 601, and is blocked by the baffle 603, so that the first connecting flange 4 with the limit groove 601 cannot pass through the baffle 603, thereby fixing the position of the first connecting flange 4 by the baffle 603.

[0021] Further, when the burner 3 needs to be installed, first insert the end of the burner 3 into the interior of the steam generator 2, so that the first connection flange 4 and the second connection flange 5 are fitted together. Then, drive the limit block 602 and the baffle 603 to move towards one side of the first connection flange 4 through the moving assembly 7, and fix both sides of the first connection flange 4 with the baffle 603 and the limit block 602, so that the first connection flange 4 cannot move in front of the second connection flange 5, thus avoiding the separation of the two flanges.

[0022] Specifically, the moving assembly includes fixing frames 701 symmetrically and fixedly connected to both sides of the second connection flange 5. A moving plate 702 for driving the limit block 602 and the baffle 603 to move is inserted into the interior of the fixing frames 701. A pushing member is arranged on one side of the fixing frames 701, and a driving member is arranged on the front of the fixing frames 701. The limit block 602 is fixedly connected to one side of the fixing frames 701, and the baffle 603 is fixedly connected to one side of the fixing frames 701. A through hole 707 is opened on the inner wall of one side of the fixing frames 701, and both the limit block 602 and the baffle 603 are inserted into the interior of the through hole 707.

[0023] It should be noted that the set limit block 602 and the baffle 603 are fixedly connected, and their cross-sections are T-shaped. The opened through hole 707 is a hole adapted to the limit block 602 and the baffle 603, and its cross-section is T-shaped, which is used to insert the limit block 602 and the baffle 603 into the interior of the fixing frames 701 through the through hole 707 during use. The set moving plate 702 is adapted to the cavity inside the fixing frames 701. The cross-section of the set moving plate 702 is square, and the cross-section of the cavity in the middle of the fixing frames 701 is square, which is used to slide the moving plate 702 inside the fixing frames 701 during use. When the moving plate 702 needs to be moved, drive the moving plate 702 to slide inside the fixing frames 701 through the pushing member and the driving member. The cross-section of the opened through hole 707 is smaller than the cross-section of the moving plate 702, which avoids the moving plate 702 moving out of the fixing frames 701 through the through hole 707 during use.

[0024] Specifically, the pushing member includes a spring 703 arranged on the other side of the moving plate 702. The spring 703 is inserted into the interior of the fixing frames 701. The driving member includes a sliding block 704 fixedly connected to the front of the moving plate 702. A driving block 706 is fixedly connected to the front of the sliding block 704. A sliding groove 705 is opened on the inner wall of the front of the fixing frames 701, and the sliding block 704 is inserted into the interior of the sliding groove 705.

[0025] It should be noted that the provided sliding groove 705 is adapted to the provided sliding block 704, and the cross-section of the provided sliding groove 705 is smaller than the cross-section of the moving plate 702, thereby preventing the moving plate 702 from moving out of the fixed frame 701 through the sliding groove 705; the provided sliding block 704 is used to connect the moving plate 702 inside the fixed frame 701 and the driving block 706 outside the fixed frame 701. When it is necessary to move the position of the moving plate 702, the driving block 706 located outside the fixed frame 701 drives the moving plate 702 to move; the provided spring 703 is used to push the moving plate 702 toward the side of the limiting block 602.

[0026] Furthermore, when it is necessary to move the limiting block 602 and the baffle 603 into the fixed frame 701, the driving block 706 located outside the fixed frame 701 drives the moving plate 702 to move. The moving plate 702 moves toward the side of the spring 703, and the spring 703 is compressed and deformed. When it is necessary to move the limiting block 602 and the baffle 603 out of the fixed frame 701, release the movement of the driving block 706. The spring 703 returns to its original shape and pushes the moving plate 702 toward the side away from the spring 703, and the limiting block 602 and the baffle 603 pass through the perforation 707 and out of the fixed frame 701.

[0027] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
