Description

Technical Field

[0001] The invention relates to the technical field of heat exchangers, in particular to a fin-type heat exchanger. Background Art

[0002] Finned heat exchanger is a common heat exchange equipment, usually used in places where heat dissipation or heating is required. It transfers heat by flowing the fluid through a tube with many fins. The setting of the fins usually increases the surface area in contact with the fluid, thereby effectively improving the heat exchange efficiency. At present, finned heat exchangers are widely used in air-conditioning systems, cooling systems, heat recovery systems in chemical processes and other systems.

[0003] Existing fin-type heat exchangers are usually composed of a bracket and a base tube. The base tubes are arranged in multiple groups, and the multiple groups of base tubes are interconnected. Fins are arranged on the base tubes. In order to reduce the volume occupied by the fin-type heat exchanger, the bracket and the base tube are usually fixedly connected by welding or other non-detachable methods. The hot fluid used in the fin-type heat exchangers currently in use is mostly water. The salt substances and dirt contained in the water are easily precipitated on the inner wall of the base tube during the heat exchange process, resulting in scaling of the inner wall of the base tube. When scaling is formed on the base tube, the heat exchange effect of the base tube will be greatly reduced, thereby increasing energy consumption and material consumption. At this time, the base tube needs to be cleaned. Since most existing heat exchangers are integral structures, the difficulty of cleaning is increased. At the same time, the mechanical cleaning method has more cleaning dead corners. When using the chemical cleaning method, chemical agents need to be used to react with scaling, which usually takes a long time and affects the normal use of the heat exchanger.

[0040] The connection method between the adapter tube 4 and the base pipe 2 is as follows: the two ends of the connecting tube 3 are respectively inserted into the two groups of base pipes 2 adjacent to each other at an oblique position. At this time, the adapter sleeve 41 is rotated to make the adapter sleeve 41 and the corresponding base pipe 2 cooperate through a threaded connection.

[0041] Combined with Figure 7 , Attachment Figure 8 , Attachment Fig. 9 , Attachment Fig.11 and attached Fig.12 As shown, the cleaning unit 6 includes a bearing block 61 and a supporting block 62 arranged in the filter tube 5, a bearing bracket 63 is rotatably provided on the bearing block 61, a supporting bracket 64 is rotatably provided on the supporting block 62, a driving paddle 66 is provided on the bearing bracket 63, and a plurality of driving paddles 66 are equidistantly arranged in a circumferential direction of the bearing bracket 63, a transmission rod 65 is provided between the bearing bracket 63 and the supporting bracket 64, a dirt removal unit 8 and a vibration unit 9 are connected to one side of the transmission rod 65, and a collecting unit 7 is connected to the other side of the transmission rod 65, the dirt removal unit 8 includes a cleaning plate 81 and cleaning bristles 82, the cleaning bristles 82 are arranged in cooperation with the filter tube 5, a plurality of cleaning bristles 82 are arranged, and the plurality of cleaning bristles 82 are evenly distributed on the cleaning plate 81.

[0042] Working principle of the cleaning unit 6: when water flows through the filter tube 5, the water flow cooperates with the driving blade 66 to drive the load-bearing bracket 63 to rotate along the load-bearing block 61, and the load-bearing bracket 63 drives the supporting bracket 64 to rotate along the supporting block 62 through the transmission rod 65 connected thereto. The setting of the supporting bracket 64 and the supporting block 62 improves the stability of the rotation of the transmission rod 65. The transmission rod 65 drives the dirt removal unit 8, the vibration unit 9 and the collecting unit 7 connected thereto to rotate. The dirt removal unit 8 removes dirt from the filter tube 5 through the rotating cleaning bristles 82, and the collecting unit 7 collects the salt substances and impurities cleaned out by the dirt removal unit 8.

[0043] Combined with Fig.11 and attached Fig.12As shown, the collecting unit 7 includes a collecting pipe 71, a water hole 72, a collecting trough 73 and a drain plate 74. The cross-section of the collecting pipe 71 is a semicircular structure. The collecting pipe 71 is connected to the end of the transmission rod 65. The water holes 72 are arranged in multiple groups, and multiple groups of water holes 72 are arranged on the collecting pipe 71. The collecting pipe 71 is connected to a collecting trough 73 at one end away from the water flow direction, and a drain plate 74 is provided at one end of the collecting trough 73.

[0044] The working principle of the collection unit 7 for collecting salt substances and impurities: the rotating collection tube 71 collects the salt substances and dirt brushed off by the cleaning bristles 82, and the water hole 72 reduces the resistance of the collection tube 71 to rotation. Due to the guidance of the water flow, the salt substances and dirt collected in the collection tube 71 will enter the collection tank 73 along the collection tube 71, and the drain plate 74 reduces the resistance of water passing through.

[0045] Combined with Fig.10 , Attachment Fig.11 and attached Fig.12 As shown, the vibration unit 9 includes a support cavity 91 arranged on the transmission rod 65, an extension column 93 is slidably provided in the support cavity 91, and a ball sleeve 94 is provided at one end of the extension column 93 extending out of the support cavity 91, and a vibration ball head 95 is rotatably provided in the ball sleeve 94, a vibration spring 92 is provided in the support cavity 91, and one end of the vibration spring 92 is connected to the extension column 93, a vibration plate 52 cooperating with the vibration unit 9 is provided in the filter tube 5, and a vibration groove 53 is provided on the vibration plate 52, and the vibration groove 53 cooperates with the vibration ball head 95, and a plurality of groups of vibration grooves 53 are equidistantly arranged along the circumferential direction of the vibration plate 52.

[0046] The working principle of the vibration unit 9 is as follows: the rotating transmission rod 65 drives the extension column 93 to rotate, and the extension column 93 drives the vibration ball head 95 to rotate through the ball sleeve 94. The elastic force generated by the deformation of the vibration spring 92 acts on the extension column 93, so that the vibration ball head 95 maintains contact with the vibration plate 52. Since multiple groups of vibration grooves 53 are equidistantly arranged on the vibration plate 52, when the vibration ball head 95 rolls through the vibration grooves 53, a slight vibration is generated, and the vibration is transmitted to the filter tube 5 through the vibration plate 52, causing the filter tube 5 to generate a slight vibration, thereby avoiding the deposition of salt substances and dirt.

[0047] Combined with Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 4 and attached Figure 5As shown, the limiting unit 10 includes a rotating column 101 rotatably arranged on a clamping plate 13, a linkage plate 102 is arranged on the rotating column 101, and the linkage plate 102 is an elliptical structure. A linkage arm 103 is rotatably arranged on the linkage plate 102, and a linkage rod 104 is rotatably arranged on the linkage arm 103. A bearing frame 105 rotatably connected to the linkage rod 104 is fixedly arranged on the supporting bracket 1, and a locking ratchet 106 is arranged on the outer side of the linkage plate 102, and an operating hole 107 is arranged on the locking ratchet 106. The operating hole 107 is a regular hexagonal countersunk structure. The locking mechanism for limiting the locking ratchet 106 includes a locking block 15 arranged on the clamping plate 13, a locking cavity 151 is arranged in the locking block 15, a sliding rod 152 is slidably arranged on the locking block 15, an operating plate 153 is arranged at the upper end of the sliding rod 152, a traction ring 154 is arranged on the operating plate 153, a locking pawl 157 cooperating with the locking ratchet 106 is arranged at the lower end of the sliding rod 152, the sliding rod 152 is located in the locking cavity 151 and is provided with a matching plate 156, a supporting spring 155 is arranged on the matching plate 156, and the supporting spring 155 is sleeved on the sliding rod 152.

[0048] The working principle of the limiting unit 10 is as follows: the locking ratchet 106 is rotated through the operating hole 107, and the locking ratchet 106 drives the linkage plate 102 connected thereto to rotate. The linkage plate 102 rotates and drives the linkage arm 103 connected thereto to rotate, and the linkage rod 104 moves synchronously. Since the linkage rod 104 is connected to the bearing frame 105 in rotation, and the bearing frame 105 is fixedly connected to the supporting bracket 1, the clamping plate 13 moves along the bearing bracket 63;

[0049] When the locking ratchet 106 rotates, the ratchet pushes the locking pawl 157 upward, and the locking pawl 157 drives the sliding rod 152 connected thereto to move synchronously. The sliding rod 152 squeezes the supporting spring 155 through the matching plate 156, and the supporting spring 155 contracts under the force. The supporting spring 155 acts in the opposite direction on the matching plate 156 through the force generated by the deformation, thereby driving the locking pawl 157 to maintain contact with the fastening ratchet through the sliding rod 152. When the locking ratchet 106 ratchet teeth push the locking pawl 157 to rise to the highest point, the locking ratchet 106 continues to rotate, and the ratchet teeth of the locking ratchet 106 lose the support for the locking pawl 157. At this time, the supporting spring 155 drives the sliding rod 152 to move downward through the matching plate 156, and the locking pawl 157 is stuck on the locking ratchet 106, preventing the locking ratchet 106 from reversing, thereby preventing the clamping plate 13 from displacement.

[0050] Combined with Figure 1 , Attachment Figure 4 , Attachment Figure 5 and attached Figure 6As shown, the clamping plate 13 is provided with a cover plate 16 that cooperates with the locking ratchet 106, and a positioning rod 14 is provided on the outer side of the clamping plate 13. The positioning rod 14 is symmetrically arranged in two groups. The cover plate 16 is provided with a positioning groove 161 that slides with the positioning rod 14, and the cover plate 16 is provided with a matching hole 162 corresponding to the operating hole 107.

[0051] When the present invention is implemented, the installation steps of the present invention are as follows:

[0052] Before installing the base pipe 2, the connecting block 22 is connected to the threaded sleeve 51 through threaded cooperation to complete the installation of the filter tube 5 and the base pipe 2. After the installation of multiple groups of base pipes 2 and filter tubes 5 is completed, the base pipe 2 is placed between the fixing plate 11 and the clamping plate 13, the limit block 21 cooperates with the limit through hole 111, and the locking ratchet 106 is rotated clockwise through the operating hole 107, and the locking ratchet 106 drives the linkage plate 102, the linkage arm 103 and the linkage rod 104 to move synchronously in turn. The clamping plate 13 moves toward the fixed plate 11, the support plate 123 drives the sliding block 122 to slide along the sliding groove 121, and the limit plates 23 at both ends of the base tube 2 respectively abut against the fixed plate 11 and the clamping plate 13, stop rotating the locking ratchet 106, and the locking pawl 157 fixes the locking ratchet 106 to realize the installation of the base tube 2 and the supporting bracket 1, and connect the connecting pipe 3 and the transfer pipe 4 to the two ends of the base tube 2 respectively, so as to realize the installation of a fin 24 type heat exchanger of the present invention.

[0053] During maintenance or replacement: when the base pipe 2 needs to be replaced, the connecting pipe 3 and the transfer pipe 4 are separated from the base pipe 2, and the traction ring 154 is pulled upward. The traction ring 154 drives the locking pawl 157 to disengage the locking ratchet 106 through the sliding rod 152. At this time, the locking ratchet 106 is in an unlocked state, and the locking ratchet 106 is rotated counterclockwise through the operating hole 107. The locking ratchet 106 drives the linkage plate 102, the linkage arm 103 and the linkage rod 104 to move synchronously in turn, and the clamping plate 13 moves away from the fixed plate 11. The support plate 123 drives the sliding block 122 to slide along the sliding groove 121. The limit plates 23 at both ends of the base pipe 2 are separated from the fixed plate 11 and the clamping plate 13 respectively. At this time, the base pipe 2 can be removed from the supporting bracket 1 for maintenance or replacement;

[0054] In daily use: water flows into the base tube 2 and is filtered through the filter tube 5, which filters the salt substances and dirt in the water flow. The water flows through the cleaning unit 6 to drive the cleaning unit 6 to rotate. The rotating cleaning unit 6 cleans the filter tube 5 through the cooperation of the collection unit 7, the decontamination unit 8 and the vibration unit 9, and collects the cleaned salt substances and dirt.
