Abstract

This utility model belongs to the technical field of quantitative conveying devices, and in particular to a quantitative conveying device for cyclobutane products. It includes a tank for storing raw materials, a pipe for inlet and outlet of the raw materials located at the center of the top of the tank, and a valve on the pipe for controlling the inlet and outlet of the raw materials.

Description

Technical Field

[0001] This utility model belongs to the technical field of quantitative conveying devices, specifically relating to a quantitative conveying device for cyclobutane-based product raw materials. Background Technology

[0002] Cyclobutane-based raw materials (gases under normal pressure) are typically transported by storing them in tanks. Quantitative delivery is achieved by controlling the internal pressure of the tank. Existing tanks are cylindrical, with a base at the bottom for support and a handle at the top for handling. The handle and base are welded to the tank. A pipe with a valve for controlling its opening and closing is located at the center of the top of the tank. However, in existing cylindrical tanks, the circumferential stress is twice the axial stress when subjected to internal pressure. This stress difference results in the cylindrical section bearing a higher load, and the overall stress distribution remains significantly discontinuous, making the cylindrical tank prone to rupture. Furthermore, the existing cylindrical tanks have a high center of gravity, making them prone to tipping over. Because the surface of the existing tanks is curved, they easily roll after tipping, which is detrimental to transportation. Therefore, a quantitative delivery device for cyclobutane-based raw materials needs to be designed to solve the aforementioned problems. Utility Model Content

[0003] To address the above problems, the purpose of this utility model is to provide a quantitative conveying device for cyclobutane products, thereby solving the problems mentioned in the background art.

[0004] This invention provides a quantitative conveying device for cyclobutane products. By setting up a spherical cavity, under the action of internal high pressure, the meridional stress and circumferential stress are equal, and the uniform distribution characteristic avoids the risk of tank rupture caused by local stress concentration.

[0005] The technical problem solved by this utility model is achieved by the following technical solution: A quantitative conveying device for cyclobutane products includes a tank for storing raw materials, a pipe for entering and exiting the raw materials with a central opening at the top of the tank, and a valve installed on the pipe for controlling the entry and exit of the raw materials. The tank is spherical, and the cavity inside the spherical tank for storing raw materials is a spherical cavity.

[0006] Preferably, the outer surface of the tank has six flat cut surfaces, namely a top cut surface, four side cut surfaces and a bottom cut surface, with the valve body and pipe located on the top cut surface.

[0007] Preferably, the four corners of the side and bottom cross-sections of the tank are provided with support legs, the support legs including bottom support legs and side support legs.

[0008] Preferably, two sets of adjacent lateral support legs are provided with protruding posts, and the other two sets of adjacent lateral support legs are provided with insertion holes that mate with the protruding posts.

[0009] Preferably, the end faces of the support legs at the four corners of the cut surface are on the same plane as the cut surface.

[0010] Preferably, the tank body is made of low-temperature resistant stainless steel.

[0011] The beneficial effects of this utility model are: by setting a spherical cavity, the stress in the radial and circumferential directions is equal under high internal pressure, and the distribution is more uniform; by setting a cross-section and supporting legs, the center of gravity of the tank is lowered, making it less prone to tipping and rolling; by setting a protruding post and a socket, the protruding post and the socket are locked and connected during stacking, which is more conducive to transportation.

[0014] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0015] An existing quantitative conveying device for cyclobutane-based raw materials mainly includes a tank 1 for storing the raw materials, a pipe 4 located at the center of the top of the tank 1, a valve 3 on the pipe 4 for controlling the entry and exit of the raw materials through the pipe 4, a handle 9 on the top of the tank 1 for carrying the tank 1, and a base 10 at the bottom of the tank 1 for supporting the tank 1. The handle 9 and the base 10 are connected to the tank 1 by welding. In use, the valve 3 of the tank 1 is opened, and then the conveying pipe is sealed to the pipe 4 of the tank 1. The cyclobutane-based raw material (gas under normal pressure) is conveyed to the tank 1 through the conveying pipe. Internally, when the pressure reaches a certain level, valve 3 is closed, and the connection between the conveying pipe and the pipeline 4 of the tank 1 is slowly disconnected. The above is the working process of an existing quantitative conveying device for cyclobutane products. The problem with the existing quantitative conveying device for cyclobutane products is that the circumferential stress is greater than the axial stress, which may lead to local stress concentration in the tank 1, increasing the risk of rupture. The cylindrical tank 1 is prone to rolling when tilted or subjected to external impact, especially on smooth or uneven ground. Rolling may damage the tank 1, which is not conducive to transportation. Therefore, the existing quantitative conveying device for cyclobutane products cannot convey materials well.

[0016] Based on the above problems, the present invention adopts the following improvement method to solve them.

[0017] like Figure 1 , 2 As shown in Figure 5, a quantitative conveying device for cyclobutane products includes a tank 1 for storing raw materials, a pipe 4 for inlet and outlet of raw materials located at the center of the top of the tank 1, and a valve 3 installed on the pipe 4 for controlling the inlet and outlet of raw materials. The tank 1 is spherical, and the cavity inside the spherical tank 1 for storing raw materials is a spherical cavity 2. The present invention is similar to the existing quantitative conveying devices for cyclobutane products in that both have a tank 1, a pipe 4, and a valve 3. The difference lies in that the tank 1 is spherical and the cavity inside the tank 1 for storing raw materials is a spherical cavity 2. The storage chamber for raw materials is designed as a spherical cavity 2, which allows the sphere to achieve the maximum volume with the minimum surface area. Under the same design pressure, its wall thickness can be reduced compared to a cylindrical container, thus reducing material consumption. Specifically, valve 3 of tank 1 is opened, and then the delivery pipe is sealed to pipe 4 of tank 1. The cyclobutane product raw material (gas under normal pressure) is delivered to the spherical cavity 2 inside tank 1 through the delivery pipe. When the pressure reaches a certain level, valve 3 is closed, and the delivery pipe is slowly disconnected from pipe 4 of tank 1. Under the action of internal high pressure, the meridional stress and circumferential stress are equal, and the uniform distribution characteristic avoids the risk of tank 1 rupture caused by local stress concentration.

[0018] Furthermore, such as Figure 2As shown, the outer surface of the tank 1 is provided with six flat cut surfaces 5. The six cut surfaces 5 are a top cut surface 5, four side cut surfaces 5 and a bottom cut surface 5. The valve body and the pipe 4 are located on the top cut surface 5. By setting the flat cut surfaces 5, the center of gravity of the tank 1 is lowered, making it less likely to tip over and cause damage to the tank 1 when rolling.

[0019] Furthermore, such as Figure 2 As shown, support legs 6 are provided at the four corners of the side cross-section 5 and the bottom cross-section 5 of the tank body 1. The support legs 6 include bottom support legs 6 and side support legs 6. By setting the support legs 6, the tank body 1 has a stronger grip on the smooth ground and will not roll and cause damage to the tank body 1.

[0020] Furthermore, such as Figure 2-4 As shown, two sets of adjacent lateral support legs 6 are provided with protruding posts 7, and two other sets of adjacent lateral support legs 6 are provided with insertion holes 8 that cooperate with the protruding posts 7. By setting the protruding posts 7 and insertion holes 8, the protruding posts 7 and insertion holes 8 are locked and connected during stacking. During transportation, vertical stacking is adopted, which will prevent tipping and damage to the tank body 1 when it rolls, which is more conducive to its transportation. During the idle period, horizontal stacking is adopted, so that the tank bodies 1 are locked and connected to each other, saving space.

[0021] Furthermore, such as Figure 2-4 As shown, the end faces of the support legs 6 at the four corners of the cross section 5 are on the same plane as the cross section 5. By setting the end faces of the support legs 6 and the cross section 5 on the same plane, the center of gravity of the tank 1 is further lowered, and there will be no tipping or rolling.

[0022] Furthermore, such as Figure 2-4 As shown, tank 1 is made of low-temperature resistant stainless steel. By making tank 1 of low-temperature resistant stainless steel, for cyclobutane raw materials (such as butylcyclobutane), stress concentration may occur due to phase change or pressure fluctuation at low temperatures. The crack propagation resistance of low-temperature resistant stainless steel can effectively delay equipment failure.
