Description

Technical Field

[0001] The invention relates to the technical field of energy-saving plate heat exchanger processing, and in particular to an energy-saving plate heat exchanger plate quick assembly device. Background Art

[0002] The energy-saving plate heat exchanger is a highly efficient heat exchange device that separates and alternately flows two fluids through a series of corrugated metal plates, allowing heat to be transferred between the fluids without mixing. The main parts of the energy-saving plate heat exchanger include: the lower fixed frame, the plates of the plate heat exchanger and the upper fixed frame, etc. The plates of the energy-saving plate heat exchanger can be disassembled and assembled for easy use and maintenance.

[0003] At present, in the process of assembling the plates of energy-saving plate heat exchangers, it is usually necessary to clamp and limit the lower fixed frame by a clamp to ensure that no displacement will occur during the subsequent assembly of the plates, resulting in installation misalignment. Then, the sealing ring is installed at the specified position of each plate, and the plates installed with the sealing ring are stacked alternately in the positive and negative directions on the lower fixed frame in sequence. Finally, the upper fixed frame is fastened to the lower fixed frame by bolts, and the plates are fixed between the upper and lower fixed frames. When tightening the bolts, they need to be fastened in a diagonal cross manner to avoid uneven force on the plates. However, in the process of assembly, the installation of the sealing ring, the alternating stacking of the plates in the positive and negative directions, and the tightening of the bolts one by one, etc., the mechanization degree and the continuous operation capacity need to be improved, and when installing the plates, it is necessary to ensure that the positioning holes of the plates are aligned with the guide rods on the lower fixed frame, and the plates are correctly installed in sequence to avoid confusion in the flow channels.

A rubber pad is provided on the side of the arc-shaped clamping part 25 close to the inlet and outlet pipe flanges at the bottom of the lower fixed frame to enhance friction. The four arc-shaped clamping parts 25 clamp and limit the lower fixed frame at the same time to prevent displacement during subsequent assembly of the plates and cause installation misalignment.

[0041] Reference Figures 4 to 5A quadrilateral support member 32 is fixed on the return slide 31, and the quadrilateral support member 32 is connected to the front and rear side walls of the return slide 31 through an L-shaped plate.

The slide rail 35 consists of two horizontal rails staggered up and down and an inclined rail connected between the two horizontal rails.

[0042] Reference Figure 4 , Figure 6 , Figure 7 and Fig.13 The feeding mechanism 6 includes a motor 61, and the motor 61 is installed on the return slide 31. The top wall of the output end of the motor 61 is fixed with a support plate 62 with four square feed grooves arranged in the circumferential direction, and a feeding assembly 63 is arranged on the support plate 62; the feeding assembly 63 includes a second feeding plate 631 corresponding to the square feed grooves one by one, and the inside of the second feeding plate 631 is provided with a square feed groove, and the inner wall of the square feed groove on the second feeding plate 631 is symmetrically slidably connected with a discharge plate 635, and the inner wall of the square feed groove on the second feeding plate 631 is symmetrically fixedly connected with a positioning cylinder 634, and the discharge plate 635 and the positioning cylinder 634 are staggered, and two non-adjacent second feeding plates 631 are symmetrically arranged. There are two adjustment blocks 633, which are composed of an L-shaped positioning pin connected to the feed tray 631 for sliding up and down through a spring and a wedge connected to the side wall of the L-shaped positioning pin through a spring rod; the support tray 62 and the feed tray 631 are both provided with holes matched with the L-shaped positioning pin, the wedge of the adjustment block 633 is matched with the slide rail 35, the feed tray 631 with the adjustment block 633 is rotatably connected to the top wall of the support tray 62, the feed tray 631 without the adjustment block 633 is fixedly connected to the top wall of the support tray 62, the feed tray 631 with the adjustment block 633 is evenly distributed with racks 632 in a semicircular shape on the circumferential side wall, and the racks 632 and the rack 1 34 are matched.

[0043] Reference Figure 3 , Figure 4 , Figure 7 and Figure 8The mounting mechanism 7 includes a balancing member 71, and a balancing member 71 is arranged on the horizontal plate of the quadrilateral support member 32. The balancing member 71 is composed of a round rod symmetrically distributed on the left and right sides and connected to the horizontal plate of the quadrilateral support member 32 by a spring and a horizontal plate fixedly connected with two round rods. A positioning column 72 is symmetrically fixed on the left bottom wall of the horizontal plate of the balancing member 71. The positioning column 72 is composed of a round rod and a sleeve under the round rod. The positioning column 72 is adapted to the positioning cylinder 634. A plurality of nail buckles with a snap-on sealing ring are fixed on the left bottom wall of the horizontal plate of the balancing member 71. Matching pressing pins 73; a mounting assembly 74 is provided on the right bottom wall of the horizontal plate of the balancing piece 71, and the mounting assembly 74 includes a balancing piece 2 741, which is composed of a horizontal plate and a round rod connected to the horizontal plate of the balancing piece 71 by a spring for sliding up and down, and a positioning column 2 742 is fixed symmetrically on the bottom wall of the balancing piece 2 741, and the positioning column 2 742 is matched with the positioning cylinder 634, and a spring rod fixedly connected to the right bottom wall of the horizontal plate of the balancing piece 71 is fixed in the middle of the horizontal plate of the balancing piece 2 741, and a U-shaped pressing piece 743 is fixed on the bottom wall of the spring rod.

[0044] The plate to be assembled is placed on the feeding assembly 63, and the motor 61 drives the supporting plate 62 to rotate counterclockwise, and the feeding assembly 63 drives the plate to be assembled to change its position, and the feeding assembly 63 assembles the snap-on sealing ring under the positioning column 72, and the feeding assembly 63 unloads the plate with the sealing ring installed under the installation assembly 74, and the plates are stacked one by one on the lower fixed frame for continuous assembly operations.

[0045] Place the snap-on sealing ring on the left plate, the bottom output end of the hydraulic rod 8 drives the balance member 71 to move downward, the spring is compressed, and the positioning column 72 moves downward into the corresponding positioning cylinder 634 for positioning, and the pressing pin 73 is pressed down onto the snap-on sealing ring. The snaps at the bottom of the snap-on sealing ring are forced into the corresponding holes of the plate, so that the snap-on sealing ring and the plate are quickly assembled and connected.

[0046] When the balancing member 71 is pressed down, the mounting assembly 74 is driven downward, and the two discharge plates 635 are driven by the electric slider to slide into the interior of the feeding tray 631, so that the square feeding trough of the feeding tray 631 changes from a closed state to an open state, and the positioning column 742 enters the corresponding positioning cylinder 634 for positioning, and continues to move downward until the sleeve of the positioning column 742 is engaged with the guide rod on the lower fixed frame for positioning. By moving the balancing member 741 and compressing the spring to adapt to the position change of the positioning column 742, the U-shaped pressing member 743 moves downward to assist in pushing the plate to move downward, and the plate is then separated from the feeding tray 631 and assembled on the lower fixed frame. In the process of the plate moving downward, the left and right sides are positioned by the positioning column 742 and the guide rod on the lower fixed frame, and the front and rear sides are limited by the U-shaped pressing member 743, so as to ensure that each plate can be aligned and assembled with the lower fixed frame.

[0047] Below the pressing pin 73 is the sealing ring installation position, and below the installation assembly 74 is the material discharge installation position. The L-shaped positioning pins on the two adjustment blocks 633 on the same feed tray 631 are connected to the return-shaped piece (not shown in the figure) inside the feed tray 631 by sliding up and down. At the sealing ring installation position and the material discharge installation position, the wedge block on the adjustment block 633 close to the slide rail 35 is in the horizontal track at the lower position of the slide rail 35. Under the connecting action of the return-shaped piece, the L-shaped positioning pins on the two adjustment blocks 633 are engaged with the holes on the support plate 62 to ensure the position stability of the support plate 62.

[0048] When the snap-on sealing ring is installed in the sealing ring installation position, the feed tray 631 carrying the plate with the sealing ring installed is displaced along with the support tray 62 rotating counterclockwise, and the wedge block of the adjustment block 633 on the feed tray 631 slides on the slide rail 35. When the plate in the feed tray 631 is unloaded, the feed tray 631 continues to rotate with the support tray 62, and the wedge block of the adjustment block 633 slides from the inclined track in the slide rail 35 into the upper horizontal track, driving the L-shaped positioning pin of the adjustment block 633 to move upward, and the L-shaped positioning pin of the adjustment block 633 changes from a state of passing through the holes of the feed tray 631 and the support tray 62 to a state of being separated from the holes of the support tray 62.

[0049] When the L-shaped positioning pin of the adjusting block 633 is disengaged from the hole of the supporting plate 62, the wedge block of the adjusting block 633 leaves the slide rail 35 as the feeding plate 631 rotates, and the spring rod connected to the wedge block of the adjusting block 633 is adaptively extended and retracted. At the same time, the next plate is placed on the feeding plate 631, and the rack 632 is meshed with the rack 1 34. The feeding plate 631 changes from a state relatively fixed with the supporting plate 62 to a state rotating on the supporting plate 62, so that the plate placed on the feeding plate 631 rotates one hundred and eighty degrees, and the front and rear plates are staggered left and right.

[0050] After the feed tray 2 631 rotates 180 degrees, the rack 2 632 and the rack 1 34 are no longer engaged. At this time, another adjustment block 633 on the feed tray 2 631 moves to the slide rail 35, and the wedge block of the adjustment block 633 slides in the lower horizontal track of the slide rail 35 and drives the L-shaped positioning pin of the adjustment block 633 to move downward. The L-shaped positioning pin of the adjustment block 633 is reset from the state of being detached from the hole of the support plate 62 to the state of passing through the hole of the feed tray 2 631 and the support plate 62. The feed tray 2 631 is reset from the state of rotating on the support plate 62 to the state of being relatively fixed with the support plate 62.

[0051] By driving the installation mechanism 7 downward through the hydraulic rod 8, the sealing ring can be installed and the plate with the sealing ring installed can be unloaded at the same time, thereby improving the processing efficiency. The fixed feed tray 631 and the rotating feed tray 631 cooperate to facilitate the mechanized positive and negative alternating sorting of the plates, thereby avoiding the low efficiency of manual installation and the occurrence of installation errors.

[0052] Reference Figures 9 to 12 The screw tightening mechanism 9 includes a movable seat 91. The left side wall of the L-shaped seat 5 is connected to the movable seat 91 by sliding up and down through an electric slider. The left side wall of the movable seat 91 is symmetrically slidably connected to the limit member 2 93 and the limit member 1 92 in a front-to-back manner. The limit member 1 92 and the limit member 2 93 are both composed of an L-shaped clamping frame and an inverted L-shaped alignment member fixed to the top wall of the L-shaped clamping frame. The inverted L-shaped alignment member of the limit member 1 92 and the inverted L-shaped alignment member of the limit member 2 93 are engaged and connected. The bottom walls of the L-shaped clamping frames of the limit members 1 92 and the limit members 2 93 are both symmetrically fixed with screw stabilizers 94; the screw stabilizers 94 are composed of The L-shaped part and the L-shaped part side wall are composed of an open circular ring part, a tightening part 95 is arranged on the inverted L-shaped alignment part of the limit part 92, and the tightening part 95 is composed of a cylinder rotatably connected to the bottom wall of the inverted L-shaped alignment part of the limit part 92 and a mounting plate sliding left and right in the middle of the cylinder, friction strips are symmetrically installed on the front and back sides of the mounting plate, the thickness of the friction strips gradually increases from left to right, and a plurality of convex teeth are evenly installed on the friction strips, and an electric push rod 96 is hinged on the right side wall of the mounting plate of the tightening part 95, and the right end of the electric push rod 96 is connected to the top wall of the movable seat 91 by a hinged electric slider for sliding back and forth.

[0053] Reference Figure 1 When all the plates are stacked and assembled on the lower fixed frame in sequence, the support mechanism 3 is driven to move to the left by the electric slider, and the traction rod 4 pulls the L-shaped seat 5 to slide to the left. The support mechanism 3 drives the feeding mechanism 6 and the installation mechanism 7 to avoid the screw tightening mechanism 9. When the feeding mechanism 6 and the installation mechanism 7 are being processed, the upper fixed frame is loaded.

[0054] The L-shaped clamping frames of limit member 1 92 and limit member 2 93 are driven by the electric slider to slide close to each other, clamp and limit the upper fixed frame from the front and rear sides, and the inverted L-shaped alignment members of limit member 1 92 and limit member 2 93 are snap-connected to enhance stability, and the bolts are inserted into the corresponding holes in the upper fixed frame and the circular ring member with an opening of the screw stabilizer 94. The circular ring of the screw stabilizer 94 is made of metal and has a certain deformation ability to maintain the stability of the bolt during movement and facilitate separation from the bolt.

[0055] The screw tightening mechanism 9 moves to the processing position above the lower fixed frame, the moving seat 91 slides downward to drive the upper fixed frame and the bolt to move downward, the upper fixed frame presses down to press the plate and the upper fixed frame, and the bolt moves downward through the lower fixed frame and enters the nut.

[0056] The electric slider connected to the electric push rod 2 96 moves back and forth to drive the tightening piece 95 to tilt. When the mounting plate of the tightening piece 95 rotates to be close to the side walls of the bolts at the two diagonal positions, the electric push rod 2 96 drives the mounting plate of the tightening piece 95 to slide on the cylinder of the tightening piece 95. When the mounting plate of the tightening piece 95 pushes the bolt to rotate, the friction force with the bolt gradually increases, and the bottom end of the rotating bolt gradually turns into the inside of the nut. The bolts are tightened twice in groups of two, so as to achieve gradual tightening, avoid uneven force on the plate, and improve assembly efficiency through mechanized tightening of bolts.

[0057] The specific operating steps of the energy-saving plate heat exchanger plate quick assembly device are as follows: place the nut in the matching hole opened on the top wall of the round seat of the base 1, place the lower fixed frame at the corresponding position of the matching hole opened on the top wall of the round seat of the base 1, and the inlet and outlet pipe flanges at the bottom of the lower fixed frame pass through the matching holes into the interior of the round seat of the base 1. The electric push rod 23 drives the four arc-shaped clamping parts 25 to clamp and limit the lower fixed frame at the same time.

[0058] The plate to be assembled is placed on the feeding assembly 63, and the hydraulic rod 8 drives the pressing pin 73 to press down on the snap-on sealing ring. The snaps at the bottom of the snap-on sealing ring are forced into the corresponding holes of the plate, so that the snap-on sealing ring and the plate are quickly assembled and connected. The U-shaped pressing piece 743 moves downward to assist in pushing the plate down and assembling it on the lower fixed frame. The fixed feeding tray 2 631 and the rotating feeding tray 2 631 cooperate to realize the alternating positive and negative sorting of the plates to form a flow channel.

[0059] When all the plates are stacked and assembled on the lower fixed frame in sequence, the movable seat 91 slides downward to drive the upper fixed frame and the bolts to move downward, and the upper fixed frame presses down to press the plates and the upper fixed frame tightly, and the electric push rod 2 96 drives the tightening part 95 to tilt and fit the bolts at two diagonal positions. The bottom end of the bolt rotates gradually into the nut to achieve gradual tightening, completing the overall assembly.
