Description

Technical Field

[0001] This utility model belongs to the field of power plant chemical water treatment technology, and specifically refers to a chemical water treatment mixing tank. Background Technology

[0002] Chemical water treatment is a crucial production process in power plants. Chemical water serves as the working and cooling medium for hot systems. It has strict quality requirements; substandard chemical water will prevent the safe and economical operation of power plant equipment. For example, when chemical water is used in high-pressure boilers, it must have low hardness, extremely low dissolved oxygen, and minimal solid and organic matter content. The preparation of chemical water typically involves adding chemical agents to purify it or adjust its composition to meet the required quality standards.

[0003] For example, the China Patent Network discloses a chemical reaction vessel for pharmaceutical production [Application No.: 201811490036.7], which includes a reaction vessel body, a support frame fixedly connected to the outside of the reaction vessel body, a horizontal bar fixedly connected to the lower end of the support frame, extension blocks fixedly connected to both sides of the lower end of the support frame, and a screw vertically inserted into the center of the extension block.

[0004] The above-mentioned connection structure between the support frame and the main body of the reaction vessel has the following defects: As can be seen from the attached drawings of the specification, the upper end of the support frame has an annular connecting part, which is fitted onto the outer circumferential surface of the main body of the reaction vessel. The connecting part and the main body of the reaction vessel are generally welded. Due to the long length of the welded position, the connection between the support frame and the main body of the reaction vessel is relatively complicated. In addition, after long-term use, the welded position is prone to corrosion, which can lead to loosening and affect the stability of the connection between the support frame and the main body of the reaction vessel. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned problems in the existing technology by proposing a chemical water treatment mixing tank. The technical problem to be solved by this utility model is: how to solve the problems of inconvenient connection between the support frame and the tank body and poor connection stability.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A chemical water treatment mixing tank includes a support frame and a tank body. The support frame has a rectangular frame at its upper end, the tank body is located within the frame, and four mounting components are equidistantly spaced along the circumferential surface of the tank body. The frame includes four profiles, each with a mounting seat fixed to it. The four mounting components correspond one-to-one with the four mounting seats. Each mounting component has a positioning hole and several first-connection holes, all one-connection holes spaced around the positioning hole. Each mounting seat has a positioning pin and several second-connection holes, all two-connection holes spaced around the positioning pin. The mounting seat abuts against the mounting component, and the positioning pin passes through the positioning hole. Each first-connection hole and its corresponding second-connection hole are coaxially aligned, and each first-connection hole and its corresponding second-connection hole are threaded with a bolt.

[0008] When assembling the tank body and support frame, the tank body is installed by hoisting from top to bottom. First, the positioning pins on the four mounting seats are inserted into the corresponding positioning holes to achieve pre-positioning, so that each connection hole one and the corresponding connection hole two are coaxial. Then, the bolts are tightened in the connection holes one and two. After multiple bolts are spaced circumferentially, the mounting seats and mounting components are fixedly connected. The tank body is fixedly connected to the four mounting seats through the four mounting components. That is, there are four fixed points between the tank body and the frame. The connection structure is stable and firm and not easy to loosen. The connection method of the tank body and support frame in this structure replaces the traditional ultra-long welding method, which significantly reduces the assembly difficulty and improves the convenience of assembly.

[0009] In the aforementioned chemical water treatment mixing tank, the mounting component includes an arc-shaped plate that fits against the outer circumferential surface of the tank body. The arc-shaped plate is welded to the tank body. The arc-shaped plate has a mounting bracket, which is integrally formed with the arc-shaped plate. The mounting bracket has a top plate. A first connecting hole and a positioning hole are both located on the top plate. A mounting cavity is located below the top plate. The mounting base has a connecting block. The upper surface of the connecting block abuts against the lower surface of the top plate. A second connecting hole and a positioning pin are both located on the connecting block. In this structure, the arc-shaped plate is fitted to the tank body before welding. The weld length between the arc-shaped plate and the tank body is relatively short. The mounting bracket is integrally formed with the arc-shaped plate; that is, the mounting bracket is positioned after the arc-shaped plate is welded to the tank body. The upper surface of the connecting block abuts against the lower surface of the top plate. Bolts lock the connecting block and the top plate together, ensuring that the connecting block and the top plate are securely fixed and not easily loosened.

[0010] In the aforementioned chemical water treatment mixing tank, the mounting base includes a base plate and a fixing strip fixed to the upper surface of the base plate. A support column is mounted on the fixing strip. The connecting block is circular, and its center is fixedly connected to the upper end of the support column. A positioning pin is located at the center of the upper surface of the connecting block, and the second connecting hole is near the outer edge of the connecting block. This mounting base has a compact structure. Because the connecting block and the fixing strip are connected by the support column, the area below the outer edge of the connecting block is left unsecured. Bolts are tightened sequentially from top to bottom into the first and second connecting holes. This allows for the selection of longer bolts that can pass through the second connecting hole to the lower position of the connecting block, thereby improving the stability of the bolt thread connection and preventing loosening.

[0011] In the aforementioned chemical water treatment mixing tank, the outer edge of the upper end of the locating pin has a chamfer. The chamfer facilitates accurate insertion of the locating pin into the locating hole.

[0012] In the aforementioned chemical water treatment mixing tank, inclined reinforcing rods are provided at the four corners of the inner side of the frame. One end of each reinforcing rod is fixedly connected to one of the profiles, and the other end is fixedly connected to another profile. This structure improves the connection strength and stability between adjacent profiles, making them less prone to loosening.

[0013] Compared with the prior art, the chemical water treatment mixing tank of this utility model has the following advantages: When assembling the tank body and the support frame, the tank body is installed by hoisting from top to bottom. First, the positioning pins on the four mounting seats are inserted into the corresponding positioning holes to achieve pre-positioning, so that each connection hole one and the corresponding connection hole two are coaxially set. Then, the bolts are tightened in the connection hole one and the connection hole two. After multiple bolts are spaced around the circumference, the mounting seats and the mounting parts are fixedly connected. The tank body is fixedly connected to the four mounting seats through the four mounting parts, that is, there are four fixed points between the tank body and the frame. The connection structure is stable and firm and not easy to loosen. The connection method of the tank body and the support frame of this structure replaces the traditional ultra-long welding method, which significantly reduces the assembly difficulty and improves the assembly convenience.

[0019] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0020] like Figures 1-4 As shown, this chemical water treatment mixing tank includes a support frame 1 and a tank body 2. The upper end of the support frame 1 has a rectangular frame 3. The tank body 2 is located inside the frame 3. Four mounting parts 4 are equidistantly arranged on the outer circumferential surface of the tank body 2. The frame 3 includes four profiles 30, and each profile 30 is fixed with a mounting seat 5. The four mounting parts 4 correspond one-to-one with the four mounting seats 5. The mounting parts 4 are provided with positioning holes 40 and several connecting holes 41. All connecting holes 41 are spaced around the positioning holes 40. The mounting seats 5 are provided with positioning pins 51 and several connecting holes 52. All connecting holes 52 are spaced around the positioning pins 51. The mounting seats 5 abut against the mounting parts 4 and the positioning pins 51 pass through the positioning holes 40. Each connecting hole 41 and the corresponding connecting hole 52 are coaxially arranged, and each connecting hole 41 and the corresponding connecting hole 52 are threaded with bolts 6. When assembling the tank body 2 and the support frame 1, the tank body 2 is installed by hoisting from top to bottom. First, the positioning pins 51 on the four mounting seats 5 are inserted into the corresponding positioning holes 40 to achieve pre-positioning, so that each connecting hole 1 41 and the corresponding connecting hole 2 52 are coaxially set. Then, the bolts 6 are tightened in the connecting holes 1 41 and 2 52. After multiple bolts 6 are set at intervals along the circumference, the mounting seats 5 and the mounting parts 4 are fixedly connected. The tank body 2 is fixedly connected to the four mounting seats 5 through the four mounting parts 4. That is, there are four fixed points between the tank body 2 and the frame 3, and the connection structure is stable and firm and not easy to loosen. The connection method of the tank body 2 and the support frame 1 in this structure replaces the traditional ultra-long welding method, which significantly reduces the assembly difficulty and improves the convenience of assembly.

[0021] like Figure 2 , Figure 3 and Figure 4As shown, the mounting component 4 includes an arc-shaped plate 42 that fits against the outer peripheral surface of the tank body 2. The arc-shaped plate 42 is welded to the tank body 2. The arc-shaped plate 42 has a mounting bracket 43, which is integrally formed with the arc-shaped plate 42. The mounting bracket 43 has a top plate 430. A first connecting hole 41 and a positioning hole 40 are both opened on the top plate 430. The bottom of the top plate 430 has a mounting cavity 7. The mounting base 5 has a connecting block 53. The upper surface of the connecting block 53 abuts against the lower surface of the top plate 430. A second connecting hole 52 and a positioning pin 51 are both provided on the connecting block 53. In this structure, the arc plate 42 is attached to the tank body 2 and then welded. The welding length between the arc plate 42 and the tank body 2 is relatively short. The mounting bracket 43 is integrally formed with the arc plate 42. That is, the mounting bracket 43 is positioned after the arc plate 42 is welded onto the tank body 2. The upper surface of the connecting block 53 abuts against the lower surface of the top plate 430. The bolt 6 locks the connecting block 53 and the top plate 430, ensuring that the connecting block 53 and the top plate 430 are firmly fixed and not easy to loosen.

[0022] like Figure 2 , Figure 3 and Figure 4 As shown, the mounting base 5 includes a base plate 54 and a fixing strip 55 fixed to the upper surface of the base plate 54. A support column 56 is provided on the fixing strip 55. The connecting block 53 is circular, and its center is fixedly connected to the upper end of the support column 56. A positioning pin 51 is located at the center of the upper surface of the connecting block 53. The second connecting hole 52 is located near the outer edge of the connecting block 53. This mounting base 5 has a compact structure. Because the connecting block 53 and the fixing strip 55 are connected by the support column 56, the area below the outer edge of the connecting block 53 is left unused. Bolts 6 are screwed into the first connecting hole 41 and the second connecting hole 52 from top to bottom. This allows for the selection of a longer bolt 6 to pass through the second connecting hole 52 and extend to the lower position of the connecting block 53, thereby improving the stability of the bolt thread connection and preventing loosening.

[0023] like Figure 2 and Figure 4 As shown, the outer edge of the upper end of the positioning pin 51 has a chamfer 510. The chamfer 510 facilitates the accurate insertion of the positioning pin 51 into the positioning hole. Inclined reinforcing rods 8 are provided at each of the four corners of the inner side of the frame 3. One end of the reinforcing rod 8 is fixedly connected to one of the profiles 30, and the other end is fixedly connected to another profile 30. This structure improves the connection strength and stability between adjacent profiles 30, making them less prone to loosening.
