Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, specifically a heat exchanger. Background Technology

[0002] A heat exchanger is a device whose main function is to transfer heat from a hot fluid to a cold fluid, ensuring that the process requires a specific temperature for the medium. Heat exchangers play an important role in industrial applications, as they can improve energy efficiency and reduce energy waste.

[0003] Chinese patent CN214842580U discloses a heat exchanger suitable for use in heat exchangers. The patent includes a housing with a combustion chamber installed in the upper part of the housing. Multiple vortex coils are installed inside the housing; a water outlet pipe is fixedly connected to the top vortex coil, and a water inlet pipe is fixedly connected to the bottom vortex coil. A condensate collection tank is fixedly installed at the bottom of the housing, and an exhaust pipe is installed on one side of the condensate collection tank. This invention increases the heat exchange contact area and time by connecting multiple vortex coils end-to-end in a layered configuration, resulting in better heating of the water. The fixing strips and limiting posts increase the contact area between the vortex coils and the high-temperature flue gas, enabling rapid heat conduction and improving heating efficiency. Furthermore, both the combustion chamber and the vortex coils are made of copper, which provides better thermal conductivity, allowing the water to heat up faster. The insulation layer reduces heat loss from the high-temperature flue gas, improving energy utilization and reducing energy consumption.

[0004] The aforementioned heat exchanger has the effect of improving energy utilization. However, in the process of heat exchange, the water in the tank cannot be fully utilized because the water flows in a single direction and very quickly. At the same time, scale easily adheres to the surface of the coil, which greatly affects the working efficiency of the heat exchanger. Therefore, a heat exchanger is needed. Utility Model Content

[0005] The purpose of this utility model is to provide a heat exchanger to solve the problems of low water resource utilization caused by the unidirectional and rapid flow of water during the heat exchange process, and the impact of scale on the surface of the coils on the working efficiency of the heat exchanger.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a heat exchanger, comprising a water tank, an inlet pipe, and an outlet pipe, wherein the inlet pipe and the outlet pipe are fixedly installed side by side on the water tank, and a coil is fixedly installed between the inlet pipe and the outlet pipe; a mixing mechanism is provided on the water tank; the mixing mechanism comprises a lower flange ring and an upper flange ring, wherein the lower flange ring is fixedly installed on the upper part of the water tank, a drive motor is fixedly installed on the upper flange ring, a rotating shaft is fixedly installed at the output end of the drive motor, a plurality of connecting rods are fixedly installed on the outside of the rotating shaft, and a shaped tube is fixedly installed on the outside of each of the plurality of connecting rods; a limiting seat is fixedly installed at the bottom of the inner wall of the water tank.

[0007] Preferably, the lower flange ring and the upper flange ring are assembled by a number of bolt groups, and the connecting rods are all installed outside the rotating shaft in a staggered manner.

[0008] Preferably, the irregular tube is composed of two trapezoidal tubes of different sizes, with the opening of the smaller trapezoidal tube facing the coil, and the rotating shaft is embedded and rotatably installed inside the limiting seat.

[0009] Preferably, a sweeping mechanism is provided on the rotating shaft. The sweeping mechanism includes a connecting seat and a connecting plate. The connecting seat is fixedly installed on the rotating shaft, and two fastening bolts are threaded in parallel between the connecting seat and the connecting plate. Two uprights are fixedly installed in parallel on the lower side of the connecting plate. A steel brush group is fixedly installed on one side of each of the two uprights, and a reinforcing plate is fixedly installed on the other side of each of the two uprights.

[0010] Preferably, both the connecting seat and the connecting plate have grooves on one side, and the grooves on the connecting seat and the connecting plate are compatible. The reinforcing plate is vertically installed on the two uprights.

[0011] Preferably, the two uprights are at the same distance from the coil, and the steel brush assembly is installed on the upright near the coil. The inlet pipe and outlet pipe are installed on the lower side of the water tank.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1) This is used in heat exchangers. The lower and upper flange rings fix the drive motor to the water tank, ensuring that the drive motor can be quickly installed and removed during use. By controlling the drive motor to drive the shaft to rotate, the shaped tube rotates synchronously around the shaft and water flows in from the wide end of the shaped tube and out from the narrow end. The shaped tube compresses the water in the water tank and sprays it at high speed onto the surface of the coil, thereby accelerating the exchange of water temperature with the coil and rapidly reducing the temperature at the coil, achieving a relatively precise and rapid cooling effect.

[0014] 2) This is used in heat exchangers. When the drive motor rotates the shaft, the upright will rotate around the shaft. The steel brush group on it will remove the scale on the surface of the coil and increase the water flow rate. Since the inlet and outlet pipes are located at the bottom of the water tank, the upright will not be obstructed by the coil when it moves. At the same time, the vertically installed reinforcing plate on the upright can increase the stability of the upright. The dirt on the coil is cleaned, which can greatly improve the cooling effect of the heat exchanger. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1.

[0023] Combination Figures 1-5A heat exchanger includes a water tank 1, an inlet pipe 2, and an outlet pipe 3. The inlet pipe is fixedly installed on the lower side of the water tank 1, and the outlet pipe is fixedly installed on the upper side of the water tank 1. The inlet pipe 2 and the outlet pipe 3 are fixedly installed side by side on the water tank 1, and a coil 4 is fixedly installed between the inlet pipe 2 and the outlet pipe 3. A mixing mechanism 5 is provided on the water tank 1. The mixing mechanism 5 includes a lower flange ring 501 and an upper flange ring 502. The lower flange ring 501 is fixedly installed on the upper part of the water tank 1, and a drive motor 503 is fixedly installed on the upper flange ring 502. A rotating shaft 504 is fixedly installed at the output end of the drive motor 503. Several connecting rods 505 are fixedly installed on the outside of the rotating shaft 504, and a special-shaped tube 506 is fixedly installed on the outside of each of the several connecting rods 505. A limiting seat 507 is fixedly installed at the bottom of the inner wall of the water tank 1.

[0024] See Figure 3 Furthermore, it is found that the lower flange ring 501 and the upper flange ring 502 are assembled by several bolt groups, and several connecting rods 505 are installed outside the rotating shaft 504 in a staggered manner. The special-shaped tube 506 is composed of two trapezoidal tubes of different sizes, and the opening of the smaller trapezoidal tube faces the coil 4. The rotating shaft 504 is embedded and rotatably installed inside the limiting seat 507.

[0025] Specifically, the drive motor 503 is fixed to the water tank 1 by the lower flange ring 501 and the upper flange ring 502, ensuring that the drive motor 503 can be quickly installed and removed during use. By controlling the drive motor 503 to drive the rotating shaft 504 to rotate, the shaped tube 506 rotates around the shaft synchronously and water flows in from the wide end of the shaped tube 506 and flows out from the narrow end, thereby increasing the speed of the water flow and mixing the water in the water tank 1. Since the narrow end of the shaped tube 506 faces the coil 2, the water flow can be sprayed onto the coil 2 to achieve relatively precise cooling of the coil 2.

[0026] Example 2.

[0027] Combination Figure 1 and Figure 4 A cleaning mechanism 6 is provided on the rotating shaft 504. The cleaning mechanism 6 includes a connecting seat 601 and a connecting plate 602. The connecting seat 601 is fixedly installed on the rotating shaft 504, and two fastening bolts 603 are threaded in parallel between the connecting seat 601 and the connecting plate 602. Two uprights 604 are fixedly installed in parallel on the lower side of the connecting plate 602. A steel brush group 605 is fixedly installed on one side of each of the two uprights 604, and a reinforcing plate 606 is fixedly installed on the other side of each of the two uprights 604.

[0028] See Figure 4Furthermore, based on Embodiment 1, grooves are provided on one side of both the connecting seat 601 and the connecting plate 602, and the grooves on the connecting seat 601 and the connecting plate 602 are compatible. The reinforcing plate 606 is vertically installed on the two uprights 604, and the two uprights 604 are at the same distance from the coil 4. The steel brush group 605 is installed on the uprights 604 near the coil 4. The liquid inlet pipe 2 and the liquid outlet pipe 3 are installed on the lower side of the water tank 1.

[0029] Specifically, the connecting seat 601 is connected to the connecting plate 602 by fastening bolts 603. When the drive motor 503 is controlled to rotate the shaft 504, the connecting plate 602 will rotate synchronously with the shaft 504, thereby causing the upright 604 to rotate around the axis. The steel brush assembly 605 on the upright 604 will continuously remove dirt from the coil 4. The steel brush assembly 605 consists of several spaced steel brushes made of stainless steel wire bundles with moderate hardness. After installation, the steel brushes on the two uprights 604... Group 605 is located on the inner and outer sides of coil 4. Some steel brushes are in contact with the inner and outer sides of coil 4 and clean the inner and outer sides of coil 4 when it rotates. Some steel brushes are inserted between the upper and lower gaps of coil 4 to clean the upper and lower sides of coil 4. Thanks to the fact that inlet pipe 2 and outlet pipe 3 are both located on the lower side of water tank, coil 4 will not obstruct upright 604 when upright 604 rotates. A reinforcing plate 606 is vertically installed on one side of upright 604 to increase the stability of upright 604.

[0030] In actual operation, the drive motor 503 is fixed to the water tank 1 by the lower flange ring 501 and the upper flange ring 502, so that the drive motor 503 can be quickly installed and removed during use. By controlling the drive motor 503 to drive the rotating shaft 504 to rotate, the special-shaped tube 506 rotates around the shaft synchronously and water flows in from the wide end of the special-shaped tube 506 and flows out from the narrow end, thereby increasing the speed of the water flow and mixing the water in the water tank 1. Since the narrow end of the special-shaped tube 506 faces the coil 2, the water flow can be sprayed onto the coil 2 to achieve relatively precise cooling of the coil 2.

[0031] The connecting seat 601 is connected to the connecting plate 602 by fastening bolts 603. When the drive motor 503 is controlled to rotate the shaft 504, the connecting plate 602 will rotate synchronously with the shaft 504, thereby causing the upright 604 to rotate around the axis. The steel brush group 605 on the upright 604 will continuously remove dirt from the coil 4. The steel brush group 605 is composed of several spaced steel brushes. The steel brushes are stainless steel wire bundles with moderate hardness. After installation, the steel brush groups 605 on the two uprights 604 will... 05 are located on the inner and outer sides of the coil 4. Some steel brushes are in contact with the inner and outer sides of the coil 4 and clean the inner and outer sides of the coil 4 when it rotates. Some steel brushes are inserted between the upper and lower gaps of the coil 4 and clean the upper and lower sides of the coil 4. Thanks to the fact that the inlet pipe 2 and the outlet pipe 3 are both located on the lower side of the water tank, the coil 4 will not obstruct the upright 604 when it rotates. A reinforcing plate 606 is vertically installed on one side of the upright 604 to increase the stability of the upright 604.
