Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to a pressure vessel, particularly a pressure vessel tank assembly. Background Technology

[0002] Pressure vessels are closed devices used to store or process media such as gases and liquids, and operate under certain pressures. They are widely used in industries such as petrochemicals, energy, and pharmaceuticals.

[0003] Existing pressure vessels, such as a novel pressure tank disclosed in the Chinese Patent Database (application number: 201611005021.8), include a tank body with an inlet and an outlet. A reciprocating circulating water pipe is provided between the inlet and outlet and is fitted to the inner wall of the tank body. The tank body is placed horizontally. A pressure gauge and a lifting ring are provided at the upper end of the tank body, with the lifting ring fixed to the upper end of the tank body near both ends. There are two support bases, each supporting the lower end of the tank body. Each support base includes a main support base and a secondary support base. The upper end of the main support base has a groove that fits the shape of the tank body, and the tank body is supported in the groove. The secondary support bases are fixed to both sides of the main support base. Each main support base has four secondary support bases. Rubber pads are fitted to the inner wall of the groove. There are three temperature alarms, which are respectively located at the top, bottom, and side of the tank body.

[0004] In the aforementioned pressure tank, the tank body is horizontally positioned, and lifting rings are fixed at both ends of the top wall of the tank. During use, the pressure tank is suspended and transported by hooking the two lifting rings with two hooks. However, this method requires adjusting the height of the two hooks to make them level in order to ensure that the pressure tank is transported horizontally. The adjustment of the hook height is basically done slowly by visual inspection, making the whole operation quite cumbersome. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a pressure vessel tank assembly that facilitates suspended transport.

[0006] The objective of this utility model can be achieved through the following technical solution: a pressure vessel tank assembly, comprising a horizontally arranged and elongated tank, characterized in that the top wall of the tank is flat, a support frame is horizontally arranged above the tank, the support frame includes a plate and four straight rods formed on the outer side wall of the plate, the ends of the straight rods away from the plate are connecting ends, the four connecting ends extend to the four corners of the aforementioned plane, and the connecting ends are fixed to the aforementioned tank through connectors; a lifting ring is fixed on the top wall of the plate.

[0007] With the cooperation of the straight rod and connecting parts, the force on the lifting ring during suspension is distributed to the four corners of the top wall of the tank, which greatly reduces the force on a single position of the tank, thereby greatly avoiding deformation and detachment of the tank during suspension transportation and effectively improving the safety of suspension transportation.

[0008] This application only requires the installation of a single lifting ring to achieve safe suspension and transportation of pressure vessels. This effectively eliminates the need for suspension and transportation operations in actual use, making it more convenient to use.

[0009] In the aforementioned pressure vessel tank assembly, the connecting component includes positioning rods, with each of the four corners of the plane vertically fixed to a positioning rod. The connecting end has clearance holes for the positioning rods to pass through. An annular limiting seat is formed on the outer wall of the positioning rod, and a locking component is fixed to the positioning rod to press the connecting end against the corresponding limiting seat. This design offers advantages such as convenient and stable connection.

[0010] In the aforementioned pressure vessel tank assembly, the locking component includes a nut screwed onto the positioning rod, and the connecting end is clamped between the corresponding nut and the corresponding limit seat. In this way, rotating the nut allows the support frame to be disassembled and assembled, facilitating assembly and maintenance.

[0011] As an alternative, in the aforementioned pressure vessel tank assembly, a circular hole is horizontally passed through the positioning rod, and the locking component includes a pin embedded in the circular hole, with both ends of the pin extending out of the circular hole, and the connecting end clamped between the corresponding pin and the corresponding limit seat.

[0012] In the aforementioned pressure vessel tank assembly, the lower end of the positioning rod is welded and fixed to the tank body.

[0013] In the aforementioned pressure vessel tank assembly, four protrusions are formed on the flat surface. Positioning holes matching the protrusions are provided on the bottom wall of the positioning rod, and each protrusion is locked into its corresponding positioning hole. The protrusions and positioning holes cooperate to pre-position the positioning rod, ensuring a stable and smooth welding process.

[0014] In the aforementioned pressure vessel tank assembly, the positioning hole has a conical surface (I) on its wall, with the diameter of the first conical surface gradually increasing from top to bottom. A second conical surface (II) matching the first conical surface is formed on the sidewall of the protrusion, and the second conical surface (II) is tightly fitted onto the corresponding first conical surface (I). The first and second conical surfaces cooperate to correct the position of the positioning rod and improve the installation accuracy of the support frame.

[0015] In the aforementioned pressure vessel tank assembly, the support frame is an integral structure.

[0016] In the aforementioned pressure vessel tank assembly, a rubber pad is horizontally positioned between the plate and the flat surface, and the rubber pad is fixed to the tank. The top and bottom surfaces of the rubber pad are respectively attached to the plate and the flat surface. The rubber pad is used to buffer the vibrations generated between the plate and the tank during suspension and to delay the loosening of the nuts.

[0017] Compared with existing technologies, this pressure vessel tank assembly has the following advantages:

[0018] 1. With the cooperation of the straight rod and connecting parts, the force on the lifting ring during suspension is distributed to the four corners of the top wall of the tank, which greatly reduces the force on a single position of the tank, thereby greatly avoiding deformation and detachment of the tank during suspension and transportation, and effectively improving the safety of suspension transportation.

[0019] 2. Conical surface one and conical surface two are used to correct the position of the positioning rod and improve the installation accuracy of the support frame.

[0020] 3. This application only requires the installation of one lifting ring to achieve safe suspension and transportation of pressure vessels. This effectively eliminates the operation steps required for suspension and transportation in actual use, making it more convenient to use. Attached Figure Description

[0025] 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.

[0026] Example 1: As Figure 1 As shown, the pressure vessel tank assembly includes a horizontally arranged and elongated tank 1. In the actual product, the cross-section of the outer wall of the tank 1 is hexagonal, and the top wall of the tank 1 is a plane 1a.

[0027] Specifically

[0028] A support frame 2 is horizontally mounted above the tank body 1. The support frame 2 is an integral structure, comprising a plate 2a and four straight rods 2b formed on the outer wall of the plate 2a. Both the straight rods 2b and the plate 2a are horizontally positioned. The ends of the straight rods 2b furthest from the plate 2a are connecting ends 2b1, and the four connecting ends 2b1 extend to the four corners of the aforementioned plane 1a, respectively. The connecting ends 2b1 are fixed to the tank body 1 via connectors. A lifting ring 3 is fixed to the top wall of the plate 2a.

[0029] With the cooperation of the straight rod 2b and the connecting parts, the force on the lifting ring 3 during suspension is distributed to the four corners of the top wall of the tank 1, which greatly reduces the force on a single position of the tank 1, thereby greatly avoiding deformation and falling off of the tank 1 during suspension transportation and effectively improving the safety of suspension transportation.

[0030] To further explain, the plate 2a is elongated and its length extends along the axial direction of the tank 1. Four straight rods 2b are distributed at the four corners of the plate 2a, and preferably each straight rod 2b has the same length.

[0031] In this embodiment,

[0032] like Figures 1 to 3 As shown, the connector includes positioning rods 4, and the positioning rods 4 are vertically fixed at all four corners of plane 1a. The connecting end 2b1 has clearance holes for the positioning rods 4 to pass through. An annular limiting seat 4a is formed on the outer wall of the positioning rod 4. The limiting seat 4a and the positioning rod 4 are coaxially arranged, and a locking element is fixed on the positioning rod 4 to press the connecting end 2b1 against the corresponding limiting seat 4a. This design offers advantages such as convenient and stable connection.

[0033] in,

[0034] like Figure 2 and Figure 3 As shown, the positioning rod 4 is installed as follows: the lower end of the positioning rod 4 presses against the tank body 1, and the positioning rod 4 is welded and fixed to the tank body 1. Further, four protrusions 1b are formed on the plane 1a, and positioning holes matching the protrusions 1b are opened on the bottom wall of the positioning rod 4, with each protrusion 1b being locked in its corresponding positioning hole. The protrusions 1b cooperate with the positioning holes to pre-position the positioning rod 4, ensuring a stable and smooth welding process. Furthermore, the wall of the positioning hole has a conical surface 4b, the diameter of which gradually increases from top to bottom. A second conical surface matching the first conical surface 4b is formed on the side wall of the protrusion 1b, and the second conical surface is tightly attached to the corresponding first conical surface 4b. The first and second conical surfaces cooperate to correct the position of the positioning rod 4 and improve the installation accuracy of the support frame 2.

[0035] The locking component includes a nut 5 screwed onto the positioning rod 4, and the connecting end 2b1 is clamped between the corresponding nut 5 and the corresponding limit seat 4a. By rotating the nut 5, the support frame 2 can be disassembled and assembled for easy assembly and maintenance.

[0036] In the actual product, a rubber pad 6 is horizontally provided between the plate 2a and the plane 1a, and the rubber pad 6 is fixed to the tank 1, with the top and bottom surfaces of the rubber pad 6 attached to the plate 2a and the plane 1a respectively. The rubber pad 6 is used to buffer the vibration generated between the plate 2a and the tank 1 during suspension and to delay the loosening of the nut 5.

[0037] Example 2: The structure and principle of Example 2 are basically the same as those of Example 1. The difference is that a circular hole is horizontally penetrating the positioning rod 4. The locking component includes a pin embedded in the circular hole. Both ends of the pin extend out of the circular hole, and the connecting end 2b1 is clamped between the corresponding pin and the corresponding limiting seat 4a.

[0038] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
