A connecting seat is provided at the bottom of the lower cylinder and is fixedly connected to the lower cylinder. The connecting seat is provided with a support foot to keep the cylinder body upright. The outer surface of the cylinder body is also provided with a heat insulation layer. This cylinder has a reasonable structure, can prevent frost and ice formation on the cylinder body, and is convenient to use.

[0004] While the above-mentioned device facilitates the replacement of support legs and reduces the cost of using the cylinder, the cylinder is quite heavy when filled with ammonia. When moving the cylinder, workers usually have to pull it with great effort, which can easily cause friction between the support legs and the ground, exacerbating the damage to the support legs. Furthermore, the cylinder is difficult to move, thus causing inconvenience to the use of the device.

[0005] Therefore, it is necessary to propose a storage tank for ultrapure ammonia to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a storage tank for ultrapure ammonia gas, in order to solve the problems mentioned in the background art, which are that the cylinder is heavy when filled with ammonia gas, and when moving the cylinder, the workers usually have to pull the cylinder with great effort, which can easily cause friction between the support feet and the ground, aggravating the damage to the support feet, and the cylinder is difficult to move, thus bringing inconvenience to the use of the device.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a storage tank for ultrapure ammonia, comprising a storage tank body, a valve threadedly connected to the top of the storage tank body, and a connecting block welded to the bottom of the storage tank body, wherein a support platform is inserted into the outside of the connecting block;

[0008] Auxiliary components are provided on both sides of the support platform. The auxiliary components include extension blocks, mounting frames, telescopic blocks, and casters.

[0009] The extension block is slidably connected to the outside of the support platform and the side of the extension block is fixedly connected to the side of the mounting frame. The top of the mounting frame is slidably connected to the outside of the extension block. The bottom of the extension block is fixedly connected to the top of the caster wheel. Adjustment holes are provided inside both the extension block and the mounting frame. A second bolt is threaded into the adjustment hole. A fixing hole is provided inside the extension block. A third bolt is threaded into the fixing hole.

[0010] Preferably, the bottom of the mounting bracket is on the same horizontal plane as the bottom of the support platform.

[0011] Preferably, multiple fixing holes are provided along the length direction of the extension block, and the outer side of the third bolt is threadedly connected to the inner side of the support platform.

[0012] Preferably, the side of the support platform is internally threaded with a first bolt, and the outside of the first bolt is inserted into the inside of the connecting block.

[0013] Preferably, the exterior of the storage tank body is covered with a polyurethane insulation layer.

[0014] Preferably, a handle is fixedly connected to the top of the storage tank body, and the handle is located outside the valve.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. By setting auxiliary components, when it is necessary to move the storage tank body, the telescopic block can be pulled down. The telescopic block will drive the caster to move downward, so that the adjustment hole of the telescopic block corresponds to the adjustment hole of the mounting bracket. Then, the second bolt is used to connect the two adjustment holes with threads to fix the telescopic block and the mounting bracket. At this time, the caster will protrude from the outside of the mounting bracket, and the caster can be used to move the storage tank body easily. This avoids the problem of pulling the storage tank body with great effort, which can easily cause the support platform to wear and be damaged. It is also more labor-saving and brings convenience to the use of the device.

[0017] 2. When the storage tank body needs to be placed, the second bolt can be removed, allowing the casters to move the telescopic block upwards under the weight of the storage tank body. At this time, the bottom of the mounting bracket and the bottom of the support platform are on the same horizontal plane. Then, according to the size of the placement site, select appropriate fixing holes and adjust the length of the telescopic block. Rotate the third bolt in the opposite direction to separate the third bolt from the support platform. Then, pull out the telescopic block, which will move the mounting bracket. Then, use the third bolt to fix the telescopic block, thereby increasing the contact area between the support platform and the ground and improving the stability of the storage tank body.
