Description

Technical Field

[0001] The utility model belongs to a spiral plate heat exchanger, in particular to a spiral plate heat exchanger. Background Art

[0002] Heat exchanger is a device that transfers part of the heat of hot fluid to cold fluid, also known as heat exchanger. Heat exchanger plays an important role in chemical, petroleum, power, food and many other industrial production. In chemical production, heat exchanger can be used as heater, cooler, condenser, evaporator and reboiler, etc., and is widely used. Spiral heat exchanger is a heat exchanger that is made of two parallel metal plates rolled into two spiral channels, and the hot and cold fluids exchange heat through the spiral plate wall.

[0003] The Chinese patent with publication number CN216385216U discloses a spiral plate heat exchanger, which includes a front moving mechanism and a rear moving mechanism, wherein the rear moving mechanism includes a rear moving plate, two rear brackets and two rear wheels, wherein the rear moving plate is fixed to the bottom ends of two legs located at the front side of the heat exchanger body, the two rear brackets are respectively mounted on both sides of the bottom of the rear moving plate, and the two rear wheels are rotatably connected to the two rear brackets through two rear rotating shafts, wherein the front moving mechanism includes a front moving plate, two front brackets, two front wheels, two transmission worm gears, two transmission rods, two locking worm gears, two locking worms, two connecting rods, a connecting block, a plurality of limit rods, a locking screw, a locking threaded tube and a locking handle, wherein the front moving plate is fixed to the bottom ends of two legs located at the rear side of the heat exchanger body.

[0004] However, the above patent has the following shortcomings:

[0005] 1. When the device needs to be fixed, the front wheel of the device can be locked through the locking structure by rotating the threaded rod. However, the above patent can only lock the front wheel, and the device is supported by two front wheels and two rear wheels. Therefore, the contact area between the device and the supporting surface is small, which makes it impossible to stably place the device.

[0006] 2. When the device is installed with a matching device, the interface direction of the device needs to be the same as the interface direction of the device. The above device lacks a structure that allows the device to be turned on the spot, so it is not convenient to quickly change the direction of the device in a narrow space. Utility Model Content

[0007] The utility model provides a spiral plate heat exchanger, aiming to solve the problem of the spiral plate heat exchanger mentioned in the above background technology.

[0008] The utility model is implemented as follows: a spiral plate heat exchanger comprises a heat exchanger body, a connecting plate is fixedly connected to the bottom of the heat exchanger body, four connecting rods are fixedly connected to the outer periphery of the bottom of the connecting plate, and the bottoms of the four connecting rods are all provided with moving wheels, a shell is fixedly connected to the center of the bottom of the connecting plate, and a supporting mechanism for supporting the device is provided at the bottom of the shell;

[0009] The support mechanism includes a height adjustment component for controlling the height of the connection plate, and an angle adjustment component for controlling the placement angle of the connection plate;

[0010] The height adjustment component includes a support frame, the support frame is arranged at the bottom of the shell, an electric push rod is arranged between the support frame and the shell, the bottom of the electric push rod is fixedly connected to the support frame, the output end of the electric push rod is fixedly connected to a rotating disk, the rotating disk is rotatably connected to the shell, and four support rods are fixedly connected to the bottom of the support frame;

[0011] The angle adjustment component includes an annular plate and a mounting plate, wherein the annular plate is arranged on the outer periphery of the housing, a plurality of fixing rods are fixedly connected between the annular plate and the support frame, and a fixed gear ring is fixedly connected to the bottom of the annular plate;

[0012] The mounting plate is arranged inside the shell, and the mounting plate is L-shaped. The bottom of the mounting plate is fixedly connected to the inner wall of the shell, and the side wall of the mounting plate is fixedly connected to a stepper motor. The output shaft of the stepper motor is fixedly connected to a driving bevel gear, and driven bevel gears are meshed on both sides of the driving bevel gear. The side walls of the two driven bevel gears are fixedly connected to rotating shafts, and the two rotating shafts are arranged through the shell. The two rotating shafts are rotatably connected to the shell, and the ends of the two rotating shafts are fixedly connected to driving gears, and the two driving gears are matched with fixed gear rings.

[0013] By starting the electric push rod, the shell and the connecting plate can be driven to move upward, and at the same time, the connecting rod and the moving wheel connected to the connecting plate will also move upward synchronously. At this time, the four moving wheels do not contact the ground, and the four support rods at the bottom of the support frame are in contact with the ground. The device is supported by the four support rods and is stably fixed on the placement surface.

[0014] When the shell moves upward, the driving gears on both sides of the shell will be meshed with the fixed gear ring on its top. At this time, the active bevel gear can be driven to rotate by starting the stepper motor, and the active bevel gear will simultaneously drive the two driven bevel gears to rotate. At this time, the two driven bevel gears will respectively drive the two driving gears to rotate in the opposite direction. Because the driving gear is meshed with the fixed gear ring, the torque generated by the rotation of the driving gear will drive the shell and the connecting plate to rotate, so that the angle of the heat exchanger body can be adjusted, and then the direction of the heat exchanger can be changed in a smaller space, so as to facilitate the connection between the heat exchanger and the equipment.

[0015] The diameter of the two driving gears is much smaller than the diameter of the fixed gear ring, so the rotational torque output by the device can be increased.

[0016] Preferably, both sides of the electric push rod are provided with stabilizing cylinders, the bottoms of the two stabilizing cylinders are fixedly connected to the support frame, the ends of the two stabilizing cylinders are slidably provided with stabilizing rods, and the tops of the two stabilizing rods are fixedly connected to the rotating disk;

[0017] The stabilizing rod can only slide along the axial direction of the stabilizing cylinder, so the two stabilizing rods can prevent the shell and the support frame from deflecting on the longitudinal axis, thereby improving the stability of the device when supporting.

[0018] Preferably, a fixing ring is provided on the outer periphery of the shell, the top of the fixing ring is fixedly connected to the connecting plate, the outer periphery of the fixing ring is threadedly connected to a protective shell, and the outer periphery of the protective shell is fixedly connected to a plurality of handles;

[0019] By providing a protective shell, the fixed gear ring and the driving gear can be shielded, thereby reducing the entry of dust between the fixed gear ring and the driving gear, thereby increasing the service life of the device. When lubricating oil is needed between the fixed gear ring and the driving gear, the protective shell can be removed by rotating the handle.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: a spiral plate heat exchanger of the present invention:

[0021] By setting a height adjustment component, when the device needs to be placed stably, the position of the support frame can be adjusted, so that the device is changed from being supported by moving wheels to being supported by support rods. Compared with the method of placing the device by moving wheels, supporting the device by support rods can make the installation method more stable. At the same time, in conjunction with the angle adjustment component, the direction of the device can be adjusted when the device is supported by the support rods, thereby facilitating the connection between the device and the equipment in a narrow space, thereby facilitating the use of the device.
