Description

Technical Field

[0001] This application relates to the field of head installation technology, specifically the installation structure of heat exchanger casting heads. Background Technology

[0002] Heat exchangers are widely used heat exchange equipment in the industrial field. The end caps, also known as end caps, are an important component of heat exchangers. The installation quality and structural design of the end caps directly affect the performance and service life of the heat exchanger.

[0003] Currently, heat exchanger heads on the market are typically installed using welding and bolt connections. Welding requires professional personnel, and the welding quality is highly dependent on the operator's skill level. Furthermore, the welding process can cause thermal deformation, affecting the overall performance of the heat exchanger. While bolt connections facilitate disassembly, bolts are prone to being lost during disassembly, leading to instability in subsequent head installations. Over long-term use, bolts are also prone to loosening, resulting in decreased sealing performance. Therefore, a new installation structure for cast heat exchanger heads has been proposed to address these issues. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides an installation structure for heat exchanger casting heads, which has advantages such as ease of installation and solves the problem of inconvenient installation.

[0005] To achieve the above objectives, this application provides the following technical solution: an installation structure for a heat exchanger casting head, comprising a heat exchanger shell and two head bodies, with a sealing ring fixed on one side of each of the two head bodies, two reinforcing ribs fixed at both the front and rear ends of each of the two head bodies, and two connecting blocks fixed at both the upper and lower ends of the heat exchanger shell, with installation components for installing the head bodies on the left and right sides of the heat exchanger shell provided inside the upper and lower sets of connecting blocks;

[0006] The installation assembly includes two sets of snap-fit ​​blocks, convex rods, screws, connecting plates fixedly installed at opposite ends of the two sets of snap-fit ​​blocks, two lifting plates fixedly installed at opposite ends of the two connecting plates, operating blocks fixedly installed at opposite ends of the left and right sets of screws, rotating blocks fixedly installed at opposite ends of the left and right sets of convex rods, and resistance structures fixedly installed at opposite ends of the upper and lower sets of snap-fit ​​blocks.

[0007] By adopting the above technical solution, the ease of installation of the head body can be effectively improved, and the phenomenon of unstable subsequent installation of the head body due to the loss of bolts can be reduced.

[0008] Furthermore, each of the two connecting blocks has two through holes on its opposite side for the card block to pass through its interior, and each of the two end caps has two card slots at its upper and lower ends for the card block to be inserted into its interior.

[0009] Using the above technical solution, the snap-fit ​​block can move in or out of the through hole, allowing it to move into the snap-fit ​​groove of the head body, thus snapping the head body onto both sides of the heat exchanger shell. Conversely, if the snap-fit ​​block moves out of the snap-fit ​​groove of the head body and into the connecting block, the head body can be removed from both sides of the heat exchanger shell.

[0010] Furthermore, each of the two lifting plates, front and rear, has a lifting groove on one side facing each other for the convex rod to slide inside it, and each of the two sets of screws, left and right, has a rotating hole on one side facing each other for the rotating block to be located inside it.

[0011] Using the above technical solution, the convex rod moves up and down within the lifting groove to push the lifting plate upward or pull it downward; the convex rod and the screw can be connected together through a rotating block, so that the screw does not drive the convex rod to rotate when it rotates, so that the screw can drive the convex rod to move left and right.

[0012] Furthermore, each of the two sets of connecting blocks has a threaded hole at one of its opposite ends for the screw to pass through, and the screw is threaded to the inside of the threaded hole.

[0013] Using the above technical solution, the screw can move in or out of the connecting block through the threaded hole, so that the screw can drive the convex rod to move left and right within the connecting block.

[0014] Furthermore, the resistance structure includes pads at opposite ends of the left and right sets of operating blocks, two resistance plates fixed to opposite ends of the upper and lower connecting plates, and two sleeve rods fixed to opposite walls of the inner cavities of the upper and lower connecting blocks, with resistance springs sleeved on the outer surfaces of the sleeve rods.

[0015] By adopting the above technical solution, the snap-fit ​​block can act as a resistance, so that the snap-fit ​​block can also be firmly snapped into the snap-fit ​​groove of the head body through the resistance spring. This can effectively reduce the phenomenon of unstable installation of the head body caused by loosening of the screw, and the gasket can further reduce the phenomenon of loosening of the screw.

[0016] Furthermore, each of the upper and lower sets of resistance plates has two elongated slots on the opposite side for the sleeve rod to extend into its interior.

[0017] By adopting the above technical solution, the sleeve rod can extend into the interior of the resistance plate through the long slot hole, so that the resistance plate can compress the resistance spring sleeved on the outer surface of the sleeve rod, and the resistance spring can exert resistance on the connecting plate through the resistance plate.

[0018] Furthermore, the two lifting plates on the same side are located between the two resistance plates on the same side.

[0019] By adopting the above technical solution, the lifting plate and the resistance plate do not interfere with each other.

[0020] Furthermore, two sealing grooves are provided at both the left and right ends of the heat exchanger shell, and the sealing ring is inserted into the inside of the sealing groove.

[0021] The above technical solution is adopted to enhance the sealing performance at the connection between the two head bodies and the heat exchanger shell.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] The installation structure of this heat exchanger casting head, with its installation components, effectively improves the ease of installation and reduces the risk of instability caused by missing bolts. Furthermore, if the bolts become loose, the locking block, via a resistance spring, securely engages with the locking groove of the head, minimizing instability caused by loose bolts. Gaskets further reduce the likelihood of bolt loosening. Attached Figure Description

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] Please see Figure 1 The installation structure of the heat exchanger casting head in this embodiment includes a heat exchanger shell 1 and two head bodies 2. A sealing ring 3 is fixed on one side of each of the two head bodies 2. Two reinforcing ribs 4 are fixed at both the front and rear ends of each of the two head bodies 2. The strength of the head bodies 2 can be improved by installing reinforcing ribs 4 at both the front and rear ends of the head bodies 2. Two connecting blocks 5 are fixed at both the upper and lower ends of the heat exchanger shell 1. The interior of the upper and lower connecting blocks 5 is provided with installation components for the head bodies 2 to be installed on the left and right sides of the heat exchanger shell 1.

[0031] In addition, two sealing grooves 6 are provided at both the left and right ends of the heat exchanger shell 1. The sealing ring 3 is inserted into the inside of the sealing groove 6. When the two end cap bodies 2 abut against the left and right walls of the heat exchanger shell 1, the sealing ring 3 can be inserted into the sealing grooves 6 at both ends of the heat exchanger shell 1, so as to enhance the sealing performance at the connection between the two end cap bodies 2 and the heat exchanger shell 1.

[0032] Please see Figures 1 to 4 The installation components in this embodiment include two sets of snap-fit ​​blocks 51, convex rods 54, screws 55, connecting plates 52 fixedly installed at opposite ends of the two sets of snap-fit ​​blocks 51, two lifting plates 53 fixedly installed at opposite ends of the two connecting plates 52, operating blocks 56 fixedly installed at opposite ends of the left and right sets of screws 55, rotating blocks 57 fixedly installed at opposite ends of the left and right sets of convex rods 54, and resistance structures fixedly installed at opposite ends of the upper and lower sets of snap-fit ​​blocks 51.

[0033] The upper and lower connecting blocks 5 each have two through holes on opposite sides for the snap-fit ​​blocks 51 to pass through. The upper and lower ends of the two end cap bodies 2 each have two snap-fit ​​slots for the snap-fit ​​blocks 51 to be inserted into. This allows the snap-fit ​​blocks 51 to move in or out of the through holes, so that the snap-fit ​​blocks 51 can move into the snap-fit ​​slots of the end cap bodies 2, and the end cap bodies 2 can be snapped and fixed to both sides of the heat exchanger shell 1. Conversely, if the snap-fit ​​blocks 51 move out of the snap-fit ​​slots of the end cap bodies 2 and move into the connecting blocks 5 through the through holes, the end cap bodies 2 can be removed from both sides of the heat exchanger shell 1.

[0034] In addition, each of the two lifting plates 53 has a lifting groove on one side facing each other, which is used for the sliding of the convex rod 54. The top groove is inclined. The convex rod 54 can push the lifting plate 53 upward or pull it downward by moving up and down in the lifting groove. Each of the two sets of screws 55 has a rotating hole at one end facing each other, which is used for the rotating block 57 to be located inside. The rotating block 57 can rotate in the screw 55 through the rotating hole, so that the convex rod 54 and the screw 55 can be connected together through the rotating block 57. The rotating hole and the rotating block 57 are both T-shaped, so that the screw 55 will not drive the convex rod 54 to rotate when it rotates, so that the screw 55 can drive the convex rod 54 to move left and right.

[0035] Furthermore, each of the two sets of connecting blocks 5 has a threaded hole at one of its opposite ends for the screw 55 to pass through. The screw 55 can move in or out of the connecting block 5 through the threaded hole so that the screw 55 can drive the convex rod 54 to move left and right in the connecting block 5. The screw 55 is threaded into the threaded hole so that it can be fixed to the connecting block 5 through the threaded connection with the threaded hole.

[0036] Please see Figures 2 to 3 In this embodiment, the resistance structure includes two sets of operating blocks 56 with opposite ends of the pads 58, and the pads 58 are in the shape of rings. The pads 58 are sleeved on the outer surface of the screw 55. The resistance structure also includes two resistance plates 59 fixed to the opposite ends of the upper and lower connecting plates 52. The resistance structure also includes two sleeve rods 510 fixed to the opposite wall of the inner cavity of the upper and lower connecting blocks 5. The outer surface of the sleeve rods 510 is sleeved with a resistance spring 511.

[0037] Secondly, each of the upper and lower sets of resistance plates 59 has two elongated slots on the opposite side for the sleeve rod 510 to extend into its interior, so that the sleeve rod 510 can extend into the interior of the resistance plate 59 through the elongated slots, so that the resistance plate 59 can compress the resistance spring 511 sleeved on the outer surface of the sleeve rod 510.

[0038] In addition, the two lifting plates 53 on the same side are located between the two resistance plates 59 on the same side, so that the two lifting plates 53 on the same side do not interfere with each other.

[0039] The working principle of the above embodiments is as follows:

[0040] In use, the two end caps 2 are positioned so that their opposite sides abut against the left and right sides of the heat exchanger shell 1. Simultaneously, the two sealing rings 3 are inserted into the sealing grooves 6 at the left and right ends of the heat exchanger shell 1. Rotating the left and right operating blocks 56 causes the left and right operating blocks 56 to drive the left and right screws 55 to rotate, gradually moving the left and right screws 55 into the left and right connecting blocks 5. This allows the left and right screws 55 to drive the left and right convex rods 54 to move relative to each other within the left and right connecting blocks 5 via the rotating block 57, causing the two convex rods 54 to move from the lifting plate 53 into the lifting groove. By moving the upper two sets of lifting plates 53 to the bottom, the upper two sets of locking blocks 51 can be pushed downwards through the connecting plate 52, so that the upper two sets of locking blocks 51 can be moved out of the connecting block 5 and inserted into the locking grooves at the top of the two end cap bodies 2. Repeat the above steps, and the lower two sets of locking blocks 51 move out of the connecting block 5 and into the locking grooves at the bottom of the end cap body 2, thereby completing the installation of the end cap body 2. This can effectively improve the convenience of the installation of the end cap body 2 and reduce the phenomenon of unstable subsequent installation of the end cap body 2 due to the loss of bolts.

[0041] Simultaneously, as the upper and lower sets of lifting plates 53 drive the upper and lower sets of connecting plates 52 to move relative to each other, the upper and lower sets of connecting plates 52 can drive the upper and lower sets of resistance plates 59 to move relative to each other, so that the sleeve rod 510 can gradually move out of the long slot of the resistance plate 59, so that the resistance plate 59 no longer squeezes the resistance spring 511, and the resistance spring 511 can exert resistance on the connecting plate 52 through the resistance plate 59, and the connecting plate 52 can exert resistance on the snap-fit ​​block 51. When the screw 55 becomes loose, the resistance spring 511 can exert resistance on the connecting plate 52 through the resistance plate 59, so that the connecting plate 52 can exert resistance on the snap-fit ​​block 51. When the screw 55 becomes loose, the snap-fit ​​block 51 can also be firmly snapped into the snap-fit ​​groove of the end cap body 2 through the resistance spring 511, thereby effectively reducing the phenomenon of unstable installation of the end cap body 2 caused by the loosening of the screw 55, and the gasket 58 can further reduce the loosening of the screw 55.
