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

[0028] like Figure 1-3 As shown, a pipeline descaling device of the utility model comprises a shell 1, a plurality of alloy chips 2 and a plurality of support members 3, wherein both ends of the shell 1 are provided with openings, and a cavity 100 connected to the opening is provided inside; the plurality of alloy chips 2 are all detachable and arranged at intervals in the cavity 100, and are all abutted against the inner wall of the cavity 100, and the plurality of alloy chips 2 are in the same straight line; the plurality of support members 3 are respectively abutted between two adjacent alloy chips 2 to enhance the strength of the alloy chips 2.

[0029] It should be noted that in order to prevent the chip from being impacted by the fluid during the operation of the equipment, avoid affecting the descaling effect and forming a safety hazard, a support member 3 is arranged between the alloy chips 2 in the device. The height of the support member 3 is consistent with the distance between the two alloy chips 2, which is used to enhance the strength of the alloy chip 2. When the fluid passes through, especially when the fluid pressure is high, the alloy chip 2 may be deformed or displaced due to the pressure. The support member 3 can effectively prevent the alloy chip 2 from deformation or displacement, maintain the stability and position of the alloy chip, and effectively ensure the normal use of the device, thereby improving the service life and stability of the device.

[0030] The shell 1 in this embodiment is cylindrical in shape, and a plurality of alloy chips 2 are arranged at equal intervals along the axial direction of the shell 1 , and the plurality of alloy chips 2 and the axis of the shell 1 are on the same straight line.

[0031] It should be noted that multiple alloy chips 2 are arranged at equal intervals along the axial direction of the shell 1, ensuring that the fluid can evenly contact each alloy chip 2 when passing through, thereby improving the descaling efficiency. All alloy chips 2 are in the same straight line with the axis of the shell 1, making the contact between the alloy chip 2 and the inner wall of the cavity 100 more uniform, further enhancing the descaling effect.

[0032] It is understandable that the shape of the shell 1 can also be a square shell, and the shape of the alloy core 2 matches the shape of the shell 1 .

[0033] The support member 3 in this embodiment is in the shape of a circular ring. There are at least three support members 3 arranged between each two adjacent alloy chips 2. At least three support members 3 are arranged tangent to each other, and at least three support members 3 are tangent to the inner wall of the shell 1.

[0034] Specifically, the support member 3 in this embodiment is a stainless steel ring, and the thickness of the support member 3 is 2 mm.

[0035] It should be noted that, in the present embodiment, the number of support members 3 is preferably 3, the three support members 3 are arranged tangent to each other, and the three support members 3 are all tangent to the inner wall of the shell 1. This arrangement can provide a larger area of ​​support effect, and there will be a certain space area at the tangent connection between the three support members 3, and the space area is used for the fixing member 4 to pass through and install several fasteners 5. Therefore, during installation, there is no need to install the support members 3 between the two alloy chips 2 in turn. During installation, only the corresponding three support members 3 need to be placed between the two alloy chips 2, and the three support members 3 need to be fit together, and then locked by the fasteners 5, thereby improving the installation efficiency.

[0036] The shell 1 in this embodiment includes two cylinders 11 and a sealing member 12, wherein the two cylinders 11 are arranged opposite to each other, and a first flange portion 110 is provided on the opposite side of the two cylinders 11; the sealing member 12 abuts between the two first flange portions 110 to seal the connection between the two cylinders 11, and the two cylinders 11 are fixedly connected by the first flange portion 110.

[0037] It should be noted that the shell 1 is divided into two cylinders 11. When the alloy chip assembly 2 needs to be disassembled and assembled, the two cylinders 11 can be disassembled and separated, and the alloy chip assembly 2 can be removed or installed from the outer shell 21, which is convenient for disassembly and assembly of the shell 1. When the two cylinders 11 are connected by the first flange part 110, the seal 12 is compressed, thereby forming a tight sealing interface between the two cylinders 11. The sealing interface can effectively prevent fluid leakage from the connection. The seal 12 is a graphite gasket.

[0038] The cylinder 11 in this embodiment includes a reduced diameter portion 111 and a solid diameter section 112, wherein the solid diameter section 112 is fixed between the first flange portion 110 and the reduced diameter portion 111, the inner diameter of the solid diameter section 112 remains unchanged, and the inner diameter of the reduced diameter portion 111 gradually decreases toward the side away from the solid diameter section 112, and the opposite sides of the two farthest alloy chips 2 are respectively abutted against the connection between the corresponding reduced diameter portion 111 and the solid diameter section 112.

[0039] It should be noted that, since the interior of the device is not a through-diameter, the fluid flowing through the through-hole 200 of the alloy chip 2 will cause a certain flow loss. If the device is made according to the diameter of the pipeline, it will cause interception, which greatly affects the process flow and cannot meet the normal production requirements. Furthermore, the device can expand the inner diameter of the shell 1 by setting the reduced diameter portion 111 and the solid diameter section 112, thereby increasing the area of ​​the alloy chip 2 and increasing the number of through-holes 200 flowing through the alloy chip 2, thereby ensuring the original process flow. At the same time, since the connection between the reduced diameter portion 111 and the solid diameter section 112 is inclined, after the alloy chip 2 is installed in the shell 1, the two farthest alloy chips 2 are opposite to each other and respectively abut against the connection between the corresponding reduced diameter portion 111 and the solid diameter section 112, thereby limiting the installation position of the entire alloy chip 2 structure, further improving the installation efficiency.

[0040] The present embodiment also includes a fixing part 4 and a plurality of fasteners 5, wherein the fixing part 4 is arranged in the shell 1, and the fixing part 4 is on the same straight line as the axis of the shell 1, and a plurality of alloy chips 2 are sleeved on the outside of the fixing part 4 and are arranged at equal intervals along the axial direction of the fixing part 4; a plurality of fasteners 5 are threadedly connected to the fixing part 4, and are arranged on both sides of each alloy chip 2 and abut against its surface, so that the plurality of alloy chips 2 are fixed on the fasteners 5, and the plurality of alloy chips 2 are formed into a structural whole, which is convenient for direct installation into the shell 1.

[0041] In this embodiment, the number of alloy chips 2 arranged in the two cylinders 11 is the same, and the multiple alloy chips 2 on both sides are symmetrically arranged with respect to the vertical center plane of the seal 12, ensuring uniform descaling of the fluid when flowing through the alloy chips 2, thereby improving the stability of the descaling mechanism.

[0042] In this embodiment, the two cylinders 11 are both provided with a second flange 6 on the opposite side. The second flange 6 has the same inner diameter as the external pipe. The cylinder 11 is fixedly connected to the external pipe through the second flange 6, which is convenient for installation with the external pipe.

[0043] The alloy core 2 in this embodiment is provided with a plurality of through holes 200 for fluid to pass through, and the plurality of through holes 200 are evenly distributed in a ring-shaped array around the axis of the alloy core 2 .

[0044] It should be noted that the diameter of the through hole 200 is 5-25 mm, which can ensure that the fluid can evenly pass through the alloy chip 2, reduce fluid resistance, and maintain the descaling effect.

[0045] Specifically, the alloy chip 2 in this embodiment is a special one composed of multiple metals, and its main components are Cu, Zn, Sn, etc. When the fluid passes through the through hole 200 of the alloy chip 2, this special alloy material contacts the medium, thereby generating a large number of tiny galvanic cells. Under the action of these tiny galvanic cells, the solubility of calcium carbonate can be increased, and the formation and growth of calcium carbonate nuclei can be inhibited; and under the adsorption of the tiny galvanic cells, the carbonate crystals are distorted, and the existence of such crystals in the form of calcite is inhibited. After the fluid passes through this device, the carbonate precipitated in the fluid has a loose, non-sticky metastable crystal structure; it can prevent the formation of new scale, and because the fluid will collide, rub, and scour when passing through this device, the solid phase particles in the solution are in a suspended and dispersed state within a certain time and distance, so that the old scale attached to the pipe wall in the form of crystals gradually melts and falls off.

[0046] Working principle:

[0047] A plurality of alloy chips 2 are sequentially sleeved on the outside of the fixing member 4 and temporarily fastened in the corresponding position by the fastener 5, and then the three support members 3 are placed between the two alloy chips 2, and the three support members 3 are made to fit each other, and then finally locked by the fastener 5 to form a complete whole, and then the whole structure is placed in the shell 1, and the two farthest alloy chips 2 have their opposite sides respectively abut against the connection between the corresponding reduced diameter portion 111 and the solid diameter section 112 to limit their position, and then the two cylinders 11 are fixed by the first flange portion 110, and the strength of the alloy chip 2 is enhanced by the set support member 3 to prevent deformation.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
