Description

TECHNICAL FIELD

[0001] The utility model relates to heat exchanger technical field more specifically, it relates to a kind of heat exchanger with multi-pipeline flow guide structure. BACKGROUND

[0002] Heat exchanger is the equipment that the part heat of hot fluid is transferred to cold fluid, also called heat exchanger. Heat exchanger is important in chemical industry, petroleum, power, food and other many industrial production, and it can be used as heater, cooler, condenser, evaporator and reboiler etc. in chemical production, and is widely used.

[0003] But the heat exchange time and liquid flow of the existing heat exchanger are usually adjusted by the power of external water pump, but in order to ensure the service life of water pump and heat exchanger, the working efficiency of water pump needs to be kept in a certain range. If the heat exchanger itself has the function of adjusting the heat exchange time and liquid flow, it can cooperate with the water pump to expand the adjustable heat exchange time and liquid flow range.

[0004] Therefore, it is necessary to provide a heat exchanger with multi-pipeline flow guide structure to solve the above problems. INVENTION CONTENTS

[0005] Based on the above problems existing in the prior art, the purpose of the embodiments of the present application is to provide a heat exchanger with multi-pipeline flow guide structure, to achieve the effect of having adjusting function.

[0006] The technical scheme adopted by the present application to solve its technical problems is: a heat exchanger with multi-pipeline flow guide structure, comprising a heat exchange cylinder, the two ends of the heat exchange cylinder are respectively fixed with a liquid inlet cylinder and a liquid outlet cylinder, a plurality of heat exchange pipes are arranged in the heat exchange cylinder, the two ends of the heat exchange pipe are respectively communicated with the liquid inlet cylinder and the liquid outlet cylinder, the two sides of the liquid inlet cylinder are respectively provided with a liquid inlet pipe and a first liquid outlet pipe, one side of the liquid outlet cylinder is provided with a second liquid outlet pipe, a rotating shaft is rotatably arranged between the two ends of the liquid inlet cylinder close to and away from the heat exchange cylinder, a partition plate is fixed on the rotating shaft, and the liquid inlet cylinder is divided into two parts by the partition plate.

[0007] Further, the side walls of the two ends of the heat exchange cylinder are respectively provided with a heat exchange water inlet and a heat exchange water outlet.

[0008] Further, a drive is fixed at one end of the liquid inlet cylinder away from the heat exchange cylinder, and the output shaft of the drive is fixed with the rotating shaft.

[0009] Further, a support frame is fixed on the rotating shaft, the support frame is adapted to the inside of the liquid inlet cylinder, and the partition plate is fixed in the inside of the support frame.

[0010] The utility model has the advantages that:

[0011] 1. When the partition separates the inlet pipe and the first outlet pipe, the first outlet pipe is opened and the second outlet pipe is closed. The liquid in the inlet pipe will flow through the heat exchange tube in sequence through one side of the partition, the outlet cylinder, the other side of the partition and the first outlet pipe. At this time, the flow rate of the heat exchanger is small, but the heat exchange time of the two liquids is long, which achieves the effect of increasing the heat exchange time. It is suitable for situations where the temperature difference that needs to be changed is large.

[0012] 2. When the edge of the partition is aligned with the inlet pipe, the first outlet pipe is closed and the second outlet pipe is opened. The liquid in the inlet pipe will flow into the outlet cylinder through the heat exchange tube and then out through the second outlet pipe. At this time, the flow rate of the heat exchanger is relatively large, but the heat exchange time between the two liquids is relatively short. This is suitable for situations where the temperature difference to be changed is small. On the one hand, it adapts to the high flow rate of the liquid during heat exchange and improves the efficiency of heat exchange; on the other hand, it avoids damage to the heat exchanger due to excessive flow rate.

[0020] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0022] In the utility model, in the case that no opposite statement is made, the orientation such as "up, down" is usually for the direction shown in the drawing, or for the vertical, perpendicular or gravity direction; similarly, for the convenience of understanding and description, "left, right" is usually for the left and right shown in the drawing; "inner, outer" refers to the inner and outer relative to the contour of each component itself, but the above orientation words are not used to limit the utility model.

[0023] As shown in Figures 1-2 The utility model provides a heat exchanger with multi -pipeline flow guide structure, including heat exchange cylinder 1, the side wall of both ends of heat exchange cylinder 1 is provided with heat exchange water inlet 11 and heat exchange water outlet 12 respectively, and the both ends of heat exchange cylinder 1 are fixed with liquid inlet cylinder 2 and liquid outlet cylinder 3 respectively, a plurality of heat exchange pipes 13 are provided in heat exchange cylinder 1, and the both ends of heat exchange pipe 13 are communicated with liquid inlet cylinder 2 and liquid outlet cylinder 3 respectively.

[0024] The both sides of liquid inlet cylinder 2 are provided with liquid inlet pipe 21 and first liquid outlet pipe 22 respectively, and one side of liquid outlet cylinder 3 is provided with second liquid outlet pipe 31.

[0025] Rotary shaft 23 is rotationally arranged between the both ends of liquid inlet cylinder 2 close to and away from heat exchange cylinder 1, rotary shaft 23 is fixed with support frame 24, support frame 24 is adapted with the inside of liquid inlet cylinder 2, and baffle 25 is fixed in support frame 24, and baffle 25 divides liquid inlet cylinder 2 into two parts.

[0026] One end of liquid inlet cylinder 2 away from heat exchange cylinder 1 is fixed with driver 26, and in the embodiment, driver 26 is motor, and the output shaft of driver 26 is fixed with rotary shaft 23.

[0027] Heat exchange pipe 13 is used for the flow of liquid between liquid inlet cylinder 2 and liquid outlet cylinder 3, and heat exchange water inlet 11 and heat exchange water outlet 12 are used for the flow of the second liquid through heat exchange cylinder 1. By being provided with a plurality of heat exchange pipes 13, the contact area of the two liquids is increased, so as to quickly exchange heat.

[0028] Driver 26 is used to drive rotary shaft 23 to rotate, so as to cooperate with support frame 24 and drive baffle 25 to rotate.

[0029] When baffle 25 separates liquid inlet pipe 21 and first liquid outlet pipe 22, first liquid outlet pipe 22 is opened, and second liquid outlet pipe 31 is closed, the liquid in liquid inlet pipe 21 will first flow into the chamber on the side of baffle 25 close to liquid inlet pipe 21, then flow into liquid outlet cylinder 3 through the heat exchange pipe 13 on the side of baffle 25 close to liquid inlet pipe 21, then flow into first liquid outlet pipe 22 through the heat exchange pipe 13 on the side of baffle 25 close to first liquid outlet pipe 22, and finally flow out through first liquid outlet pipe 22, at this time, the flow of the heat exchanger is small, but the heat exchange time of the two liquids is long, which achieves the effect of increasing the heat exchange time, and is suitable for the case that the temperature difference to be changed is large.

[0030] When the edge of the partition plate 25 is aligned with the inlet pipe 21, the first outlet pipe 22 is closed, and the second outlet pipe 31 is opened, the liquid in the inlet pipe 21 can flow into the chambers on both sides of the partition plate 25 at the same time, flow into the outlet cylinder 3 through the heat exchange pipe 13, and finally flow out through the second outlet pipe 31. At this time, the flow capacity of the heat exchanger is relatively large, but the heat exchange time of the two liquids is relatively short, which is suitable for the case that the required temperature difference is small. On the one hand, the high flow of the liquid is adapted to the heat exchange, and the heat exchange efficiency is improved. On the other hand, the damage of the heat exchanger caused by the excessive flow is avoided.

[0031] In summary, the user can select the heat exchange mode with a longer heat exchange time or a larger liquid flow according to the needs.

[0032] At the same time, through the above two states, the heat exchanger itself has the control flow effect, can heat exchange the two liquids in turn, and makes the two liquids flow out from the first outlet pipe 22 and the second outlet pipe 31 respectively.
