[0001] This utility model belongs to the field of plate sandblasting technology, specifically a heat exchanger plate sandblasting device. Background Technology

[0002] A heat exchanger sealing plate sandblasting device is a piece of equipment used to sandblast the sealing plates of a heat exchanger. This device is mainly used to improve the surface roughness of the sealing plate and enhance its sealing effect. However, when existing heat exchanger sealing plate sandblasting devices are used to sandblast the heat exchanger sealing plates, the sand tends to scatter in all directions, making it inconvenient to collect and recycle it. Furthermore, the sandblasting height cannot be freely adjusted, resulting in incomplete sandblasting. Therefore, a heat exchanger sealing plate sandblasting device that facilitates sand collection and sandblasting height adjustment is needed. Summary of the Invention

[0003] To overcome the above-mentioned defects, this utility model provides a heat exchanger sealing plate sandblasting device, which solves the problems that when sandblasting heat exchanger sealing plates, the sprayed sand is easy to scatter everywhere, making it inconvenient to collect and recycle, and the sandblasting height cannot be freely adjusted, resulting in incomplete sandblasting.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a heat exchanger sealing plate sandblasting device, comprising a shell, a collecting plate fixedly connected to the inner wall of the shell, an arc-shaped plate installed on one side of the collecting plate, a first motor provided above the arc-shaped plate, one side of the first motor fixedly connected to the inner wall of the shell, an auger installed on one side of the first motor, one end of the auger being interlocked with the shell, an outlet being provided below the auger corresponding to the shell, a storage tank being installed on one side of the outlet, the storage tank being fixedly connected to the outer side of the shell, a sand inlet pipe being installed on the storage tank, the outer side of the sand inlet pipe being interlocked with the collecting plate, a sandblasting strip fixedly connected to the top of the sand inlet pipe, and a nozzle being installed on one side of the sandblasting strip.

[0005] As a further embodiment of this utility model: a threaded rod is threadedly connected to one side of the sandblasting strip, a first bearing is installed at the bottom end of the threaded rod, a fixing plate is fixedly connected to the bottom side of the first bearing, a second motor is installed at the top end of the threaded rod, and the second motor is fixedly connected to the inner wall of the outer casing.

[0006] As a further embodiment of this utility model: a third motor is fixedly connected to the inner wall of the outer shell, and a first bracket is installed on the bottom side of the third motor.

[0007] As a further embodiment of this utility model: a spring is fixedly connected to the first bracket, a clamp is installed at one end of the spring, a telescopic rod is fixedly connected to one side of the clamp, and one end of the telescopic rod is fixedly connected to the first bracket.

[0008] As a further embodiment of this utility model: a second bracket is fixedly connected to the inner wall of the outer shell, a second bearing is installed on the second bracket, and two limiting plates are fixedly connected to the second bearing.

[0009] As a further embodiment of this utility model: four anti-slip pads are installed on the bottom of the outer shell, and the four anti-slip pads are respectively arranged at the four corners of the bottom of the outer shell.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This heat exchanger sealing plate sandblasting device, consisting of a collection plate, an arc-shaped plate, a first motor, an auger, a discharge port, a storage tank, a sand inlet pipe, sandblasting strips, and nozzles, allows for sandblasting of the heat exchanger sealing plates. When sandblasting, the operator activates the sandblasting strips, drawing sand from the storage tank, through the sand inlet pipe, and then spraying it out from the nozzles. Excess sand falls onto the collection plate and collects on the arc-shaped plate. The operator then activates the first motor to rotate the auger, which evenly pushes the sand on the arc-shaped plate towards the discharge port, ultimately discharging it into the storage tank. This sandblasting process facilitates the collection and recycling of excess sand, effectively preventing resource waste and improving sand utilization.

[0012] This heat exchanger sealing plate sandblasting device, by setting up sandblasting strips, threaded rods, fixed plates, a first bearing, and a second motor, allows the operator to start the second motor to drive the threaded rod to rotate when sandblasting the heat exchanger sealing plate. The threaded rod then drives the first bearing to rotate, and the threaded rod pushes the sandblasting strips up and down, thereby adjusting the sandblasting height. This facilitates comprehensive sandblasting of the heat exchanger sealing plate and prevents dead corners from being missed due to a fixed sandblasting height. Attached Figure Description

[0018] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0019] like Figure 1-4 As shown, this utility model provides a technical solution: a heat exchanger sealing plate sandblasting device, including a shell 1, a third motor 14 fixedly connected to the inner wall of the shell 1, a first bracket 15 installed on the bottom side of the third motor 14, and a collecting plate 2 fixedly connected to the inner wall of the shell 1. Because of the collecting plate 2, excess sand generated during sandblasting falls onto the collecting plate 2. Due to the inclined surface of the collecting plate 2, the sand collects at the bottom of the collecting plate 2, which facilitates the centralized treatment of excess sand. An arc plate 3 is installed on one side of the collecting plate 2.

[0020] A spring 16 is fixedly connected to the first bracket 15. A clamping plate 17 is installed at one end of the spring 16. A telescopic rod 18 is fixedly connected to one side of the clamping plate 17. One end of the telescopic rod 18 is fixedly connected to the first bracket 15. Because of the spring 16, when the heat exchanger sealing plate is fixed by the clamping plate 17, the clamping plate 17 squeezes the spring 16 to deform the spring 16. The spring 16 returns to its original position and pushes the clamping plate 17 to further fix the heat exchanger sealing plate, which improves the stability of fixing the heat exchanger sealing plate. A first motor 4 is provided above the arc plate 3. One side of the first motor 4 is fixedly connected to the inner wall of the outer shell 1. An auger 5 is installed on one side of the first motor 4. One end of the auger 5 is interlocked with the outer shell 1. An outlet 6 is opened below the auger 5 corresponding to the outer shell 1. A storage tank 7 is installed on one side of the outlet 6. The storage tank 7 is fixedly connected to the outer side of the outer shell 1.

[0021] A second bracket 19 is fixedly connected to the inner wall of the outer shell 1. A second bearing 20 is installed on the second bracket 19. Two limiting plates 21 are fixedly connected to the second bearing 20. Because of the second bearing 20, the limiting plates 21 are fixed while ensuring that the limiting plates 21 can rotate freely, which improves the stability of the rotation of the limiting plates 21. A sand inlet pipe 8 is installed on the storage tank 7. The outer side of the sand inlet pipe 8 is interlocked with the collection plate 2. A sandblasting strip 9 is fixedly connected to the top of the sand inlet pipe 8. A nozzle 10 is installed on one side of the sandblasting strip 9.

[0022] A threaded rod 11 is threadedly connected to one side of the sandblasting strip 9. A first bearing 23 is installed at the bottom of the threaded rod 11, and a fixing plate 12 is fixedly connected to the bottom side of the first bearing 23. A second motor 13 is installed at the top of the threaded rod 11 and is fixedly connected to the inner wall of the outer casing 1. Because of the first bearing 23, the threaded rod 11 is limited while ensuring its rotation, thus improving the stability of the rotation. Four anti-slip pads 22 are installed at the bottom of the outer casing 1, and are respectively arranged at the four corners of the bottom of the outer casing 1. Because of the anti-slip pads 22, the friction between the device and the ground is increased, preventing the device from sliding due to accidents and improving the stability of the device.

[0023] The working principle of this utility model is as follows: When the heat exchanger sealing plate is sandblasted, the operator inserts the heat exchanger sealing plate into the two limiting plates 21, and then into the clamping plate 17 to fix the sealing plate. The operator starts the second motor 13 to drive the threaded rod 11 to rotate. The threaded rod 11 drives the first bearing 23 to rotate. The threaded rod 11 pushes the sandblasting strip 9 up and down, thereby adjusting the sandblasting height. The operator starts the sandblasting strip 9 to suck sand from the storage tank 7, which enters the sandblasting strip 9 through the sand inlet pipe 8, and is then sprayed out from the nozzle 10 to sandblast the heat exchanger sealing plate. Excess sand falls onto the collecting plate 2 and then collects on the arc plate 3. The operator starts the first motor 4 to drive the auger 5 to rotate. The auger 5 pushes the sand on the arc plate 3 evenly toward the discharge port 6, and then discharges it into the storage tank 7.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
