DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] like Figures 1 to 8 As shown, an embodiment of the present invention provides a plate heat exchanger skid, including a bracket 1, a bracket 2, and a bracket 3, wherein the bracket 2 2 is hinged to the upper part of the bracket 1, and the bracket 3 3 is hinged to the upper part of the bracket 2 2;

[0029] A protective shell 4 is fixedly installed at the bottom of the bracket three 3, and a handle 5 is rotatably installed on one side of the protective shell 4, a connecting rod 6 is fixedly installed on one end of the handle 5, one end of the connecting rod 6 extends to the interior of the protective shell 4 and is fixedly installed with a threaded rod 7, the outer surface of the threaded rod 7 is threadedly sleeved with a threaded block 19 and a threaded block 2 10, the outer surface of the threaded rod 17 is movably sleeved with a baffle 8, the baffle 8 is fixedly connected to the inner side of the protective shell 4, the tops of the threaded block 19 and the threaded block 2 10 extend to the top of the protective shell 4, and a mounting plate 11 and a mounting plate 2 12 are fixedly installed above the threaded block 19 and the threaded block 2 10 respectively, and a top pipe 13 is movably installed between the mounting plate 11 and the mounting plate 2 12.

[0030] When the staff uses it, they first place the top pipe 13 between the mounting plate 11 and the mounting plate 2 12, and then turn the handle 5. When the handle 5 is turned, it will drive the connecting rod 6 to rotate. When the connecting rod 6 is turned, it will drive the threaded rod 1 7 to rotate. When the threaded rod 1 7 is rotated, since the connection between the threaded block 1 9 and the threaded block 2 10 and the threaded rod 1 7 is provided with threads, the rotation of the threaded rod 1 7 will drive the threaded block 1 9 and the threaded block 2 10 to approach each other. When the threaded block 1 9 and the threaded block 2 10 are close to each other, they will drive the mounting plate 11 and the mounting plate 2 12 to approach each other, thereby fixing the top pipe 13.

[0031] By placing the top pipe 13 in the middle position of the mounting plate 11 and the mounting plate 2 12, the connecting rod 6 and the threaded rod 1 7 are driven to rotate by turning the handle 5. During the rotation of the threaded rod 1 7, the threaded block 1 9 and the threaded block 2 10 are driven to approach each other, and the mounting plate 1 11 and the mounting plate 2 12 are also driven to approach each other, thereby clamping the top pipe 13. Compared with the traditional device, the device is easy to carry by installing the top pipe 13, can reduce the inconvenience of moving the device, makes the transportation of the device less difficult, and improves the working efficiency of the device.

[0032] Among them, a fixing block 20 is fixedly installed on one side of the bracket two 2, a shell 14 is fixedly installed on the bottom of the bracket three 3, a fixing plate 15 is fixedly installed on one side inside the shell 14, a spring 16 is fixedly installed on the bottom of the fixing plate 15, a fixing plate 18 is fixedly installed on the bottom of the spring 16, a latch 19 is fixedly installed on the bottom of the fixing plate 18, the bottom of the latch 19 passes through one side of the shell 14 and through the upper and lower sides of the fixing block 20, a moving rod 17 is fixedly installed above the fixing plate 18, and the top of the moving rod 17 successively passes through the upper and lower sides of the fixing plate 15, one side of the shell 14 and the upper and lower sides of the bracket three 3.

[0033] When the staff needs to retract bracket 1, bracket 2 2 and bracket 3 3, the staff first moves the moving rod 17 upwards. When the moving rod 17 moves upward, it will drive the fixed plate 18 to move upward. When the fixed plate 18 moves upward, the spring 16 will be compressed by the fixed plate 18 upward. As the spring 16 is compressed, the upward movement of the fixed plate 18 will drive the latch 19 to move upward. When the latch 19 moves upward, the bottom of the latch 19 will gradually move out of the interior of the fixed block 20. When the bottom end of the latch 19 is completely moved out of the interior of the fixed block 20, the bracket 2 2 can be rotated around the connection between the bracket 2 2 and the bracket 1 1 to retract it.

[0034] By moving the moving rod 17 upward, the fixing plate 18 is driven to move upward, thereby driving the latch 19 to move upward, so that the bottom of the latch 19 is completely moved out of the interior of the fixing block 20. When one end of the latch 19 is completely moved out of the interior of the fixing block 20, the bracket 1 1, the bracket 2 2 and the bracket 3 3 can be retracted. Compared with the traditional device, the device can reduce the occupied space of the device by retracting the bracket 1 1, the bracket 2 2 and the bracket 3 3, and it is also convenient for carrying the device.

[0035] Among them, a heat exchanger 21 is fixedly installed on the top of the bracket 1, a connecting box 27 is fixedly installed on the bottom of the top pipe 13, a plate exchange secondary side water outlet 24 and a plate exchange primary side water inlet 25 are opened on one side of the heat exchanger 21, and the number of connecting boxes 27 is two, both of which are fixedly arranged at the bottom of the top pipe 13, one end of the connecting box 27 is fixedly connected to a connecting pipe 29, one end of the plate exchange secondary side water outlet 24 is connected to a connecting pipe 3 30, the connecting pipe 3 30 and one end of the connecting pipe 2 29 are movably connected, and a sleeve is movably installed on the outer side of the connecting pipe 3 30 A sleeve 31 is hinged at one end of the sleeve 31 with a sleeve 2 32, a knob 33 is rotatably mounted on one side of the sleeve 31, a threaded rod 2 34 is movably mounted on one side of the knob 33, one end of the threaded rod 2 34 successively passes through the left and right sides of the knob 33, the sleeve 1 31 and the sleeve 2 32, the threaded rod 2 34 is threadedly sleeved with the knob 33, a limit plate 35 is fixedly mounted on the other end of the threaded rod 2 34, a sliding rod 36 is fixedly mounted on one side of the sleeve 1 31, the sliding rod 36 is movably sleeved with the limit plate 35, and the sleeve 1 31 and the sleeve 2 32 are movably connected with the connecting pipe 29.

[0036] When the staff uses it, the staff first turns the knob 33. When the knob 33 is turned, since the connection between the knob 33 and the threaded rod 34 is provided with the same thread as the threaded rod 34, the rotation of the knob 33 will drive the threaded rod 34 to move backward. When the threaded rod 34 moves backward, the limit plate 35 will slide backward on the upper side of the slide rod 36. As the threaded rod 34 moves backward, one end of the threaded rod 34 will gradually move out of the interior of the sleeve 32. When one end of the threaded rod 34 is completely moved out of the interior of the sleeve 32, the knob 33 can be stopped, so that the sleeve 32 and the sleeve 1 31 are removed from the outer surface of the connecting pipe 30.

[0037] By turning the knob 33, the threaded rod 2 34 is driven to move backward. When the threaded rod 2 34 moves backward, it will drive the limit plate 35 to move backward on the upper side of the slide rod 36. When one end of the threaded rod 2 34 is completely moved out of the interior of the sleeve 2 32, the sleeve 1 31 and the sleeve 2 32 can be removed from the outer surfaces of the connecting tube 3 30 and the connecting tube 2 29. Compared with the traditional device, the device can improve the convenience when disassembling the connecting tube 2 29 and the connecting tube 3 30 by fixing the connection between the connecting tube 2 29 and the connecting tube 3 30, thereby improving the working efficiency of the device.

[0038] There are two baffles 8 , which are respectively arranged on one side of the thread block 1 9 and the thread block 2 10 and are movably connected to the thread block 1 9 and the thread block 2 10 .

[0039] The design of the baffle 8 can prevent the threaded block 1 9 and the threaded block 2 10 from being separated from the top of the threaded rod 1 7 when moving.

[0040] Among them, a connection box 26 is fixedly installed at the bottom of the top pipe 13, and the number of the connection boxes 26 is two, and both are arranged at the bottom of the top pipe 13.

[0041] Through the design of the connection box 26, it is convenient for the water inside the top pipe 13 to enter the interior of the connection box 26, thereby facilitating the connection with the connection pipe 28.

[0042] Among them, one end of the connecting box 26 is fixedly connected to a connecting pipe 28, and one end of the connecting pipe 28 is fixedly connected to the secondary side water inlet 22 of the plate heat exchanger above the heat exchanger 21.

[0043] The design of the connecting pipe 28 facilitates the water inside the connecting box 26 to enter the interior of the heat exchanger 21 .

[0044] Among them, a plate heat exchanger primary side water outlet 23 is opened on one side of the heat exchanger 21, and the plate heat exchanger primary side water outlet 23 is fixedly connected to another connection box 26 through a connecting pipe 28.

[0045] The design of the water outlet 23 on the primary side of the plate heat exchanger facilitates the water inside the heat exchanger 21 to flow out to the inside of another connecting box 26 .

[0046] There are four top pipes 13 , and the four top pipes 13 are evenly and movably arranged above the bracket three 3 .

[0047] The design of the four top pipes 13 increases the water storage capacity, thereby facilitating the improvement of the working efficiency of the device.

[0048] Working principle and usage process:

[0049] When the staff uses it, they first place the top pipe 13 between the mounting plate 11 and the mounting plate 2 12, and then turn the handle 5. When the handle 5 is turned, it will drive the connecting rod 6 to rotate. When the connecting rod 6 is turned, it will drive the threaded rod 1 7 to rotate. When the threaded rod 1 7 is rotated, since the connection between the threaded block 1 9 and the threaded block 2 10 and the threaded rod 1 7 is provided with threads, the rotation of the threaded rod 1 7 will drive the threaded block 1 9 and the threaded block 2 10 to approach each other. When the threaded block 1 9 and the threaded block 2 10 are close to each other, they will drive the mounting plate 11 and the mounting plate 2 12 to approach each other, thereby fixing the top pipe 13.

[0050] When the staff needs to retract bracket 1, bracket 2 2 and bracket 3 3, the staff first moves the moving rod 17 upwards. When the moving rod 17 moves upward, it will drive the fixed plate 18 to move upward. When the fixed plate 18 moves upward, the spring 16 will be compressed by the fixed plate 18 upward. As the spring 16 is compressed, the upward movement of the fixed plate 18 will drive the latch 19 to move upward. When the latch 19 moves upward, the bottom of the latch 19 will gradually move out of the interior of the fixed block 20. When the bottom end of the latch 19 is completely moved out of the interior of the fixed block 20, the bracket 2 2 can be rotated around the connection between the bracket 2 2 and the bracket 1 1 to retract it.

[0051] When the staff uses it, the staff first turns the knob 33. When the knob 33 is turned, since the connection between the knob 33 and the threaded rod 34 is provided with the same thread as the threaded rod 34, the rotation of the knob 33 will drive the threaded rod 34 to move backward. When the threaded rod 34 moves backward, the limit plate 35 will slide backward on the upper side of the slide rod 36. As the threaded rod 34 moves backward, one end of the threaded rod 34 will gradually move out of the interior of the sleeve 32. When one end of the threaded rod 34 is completely moved out of the interior of the sleeve 32, the knob 33 can be stopped, so that the sleeve 32 and the sleeve 1 31 are removed from the outer surface of the connecting pipe 30.
