Description

Technical Field

[0001] This utility model relates to the field of chemical storage technology, and in particular to a chemical storage tank with anti-static function. Background Technology

[0002] In the current chemical industry, storage containers made of plastic or composite materials are widely used for the storage and transportation of liquid chemicals. However, due to the insulating properties of these materials, static electricity can easily accumulate during use due to liquid flow, friction, and handling. When static electricity cannot be discharged effectively and promptly, it can easily cause safety accidents such as electric arcs and fires in high-risk environments, posing a serious safety hazard, especially when storing flammable, explosive, or highly volatile chemicals.

[0003] To address these issues, some products have attempted to incorporate conductive particles into the barrel material or install grounding leads. However, due to the simple structure of the grounding device or the lack of a continuous conductive path between the lid and the barrel, the electrostatic discharge path is interrupted. Especially when the lid is closed, potential islands are formed between the barrel and the lid, hindering overall electrostatic discharge. Furthermore, most traditional grounding structures are rigidly fixed, unable to adapt to the stable grounding requirements of different ground environments, resulting in poor performance and safety blind spots.

[0004] Therefore, we propose a chemical storage tank with anti-static function to solve the existing problems. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a chemical storage tank with anti-static function.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a chemical storage tank with anti-static function, comprising a tank body, a tank lid, and a conductive sealing ring. Lower conductive strips are fixedly arranged at equal intervals on the inner wall of the tank body. A support base is fixedly arranged on the lower surface of the tank body. A grounding rod is slidably arranged inside the support base. The grounding rod is electrically connected to the lower conductive strips. A support spring is fixedly arranged on the grounding rod. The support spring applies a pushing force to the grounding rod to make it protrude from the lower surface of the support base.

[0007] A ring plate is rotatably mounted on the barrel lid, and an upper conductive strip is embedded in the ring plate. The barrel lid is threaded onto the outer wall of the top opening of the barrel body. A conductive sealing ring is fixedly mounted on the lower surface of the ring plate and presses against the top opening of the barrel body. When the barrel lid is closed, it forms a complete conductive closed loop with the barrel body through the conductive sealing ring.

[0008] Preferably, a spring wire is fixedly provided at the bottom end of the lower conductive strip, and the bottom end of the spring wire is fixedly provided on the grounding rod.

[0009] Preferably, the support spring is located in the inner cavity of the support base, one end of the support spring abuts against the top of the inner wall of the cavity, the other end of the support spring abuts against the grounding rod, and the original length of the support spring is greater than the height of the support base.

[0010] Preferably, the outer wall of the bucket lid is fixedly provided with a lever structure at equal intervals.

[0011] Preferably, the two ends of the upper conductive strip are in contact with the upper surface of the conductive sealing ring, and the top end of the lower conductive strip is in contact with the lower surface of the conductive sealing ring.

[0012] Preferably, there are four support seats in total, and the four support seats are arranged in a ring array on the lower surface of the barrel.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This utility model relates to a chemical storage tank with anti-static function. During use, chemical liquids are stored in the tank, and then the lid is screwed on. The engagement of the threads completes the sealing of the tank. The conductive sealing ring is a rubber ring with carbon black and graphite added, which has a conductive effect. The sealing ring is embedded between the tank opening and the lid. When the lid is tightened, the conductive sealing ring contacts the two contacts of the upper conductive strip inside the lid and the top contact of the lower conductive strip. At this time, the conductive sealing ring is in contact with the conductive parts of the tank body and the lid. From an electrical point of view, this is equivalent to establishing a low-resistance conductive path between the tank body and the lid, making the entire tank structure an electrical continuum.

[0015] During the process of placing the barrel on the ground, the grounding rod retracts into the support base under the action of gravity. At this time, the grounding rod compresses the support spring to deform it. Under the elastic force of the support spring, the grounding rod makes stable contact with the ground, avoiding the phenomenon of unstable contact between the grounding rod and the ground due to uneven ground. Through the above, a complete grounding discharge path is formed, preventing a certain area from becoming a potential island and reducing the risk of discharge, arcing, and sparking.

[0016] This utility model achieves a closed-loop conductivity between the bucket body and the bucket lid by embedding a conductive sealing ring at the joint surface between the bucket lid and the bucket body, and making contact with the upper conductive strip and the lower conductive strip respectively, thereby avoiding electrostatic disconnection problems and improving overall conductivity.

[0017] The lower conductive strip is connected to the grounding rod via a spring wire, and the conductive path is connected layer by layer, forming a continuous closed loop from the lid to the bottom of the bucket, realizing efficient electrostatic discharge. Through the elastic control grounding rod structure, even if the ground is uneven, the grounding rod can maintain stable contact with the ground, forming a continuous and reliable discharge path, avoiding the risk of discharge caused by poor grounding contact.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] like Figures 1-4 As shown, the present invention proposes a chemical storage tank with anti-static function, comprising a tank body 2, a tank lid 3, and a conductive sealing ring 7, wherein:

[0027] The barrel body 2 is a hollow cylindrical structure, and lower conductive strips 6 are fixedly arranged at equal intervals along the height of the barrel on its inner wall. The lower conductive strips 6 are made of carbon fiber strips or graphite conductive sheets and are used to provide a vertical conductive path.

[0028] A support base 1 is fixedly installed on the lower surface of the barrel 2. Preferably, four support bases are arranged in a circular array and evenly distributed in the bottom edge area of ​​the barrel. Each support base 1 has a vertical sliding cavity inside. A grounding rod 10 is slidably installed in the sliding cavity. The grounding rod 10 can be made of copper rod or conductive alloy rod. Its lower end can extend out of the support base 1 to contact the ground.

[0029] To ensure continuous contact between the grounding rod 10 and the ground, a support spring 9 is provided in the sliding cavity of the support base 1. One end of the support spring 9 abuts against the top of the sliding cavity, and the other end abuts against the grounding rod 10. The original length of the support spring 9 is greater than the height of the support base 1. When in a compressed state, it pushes the grounding rod 10 downward, thereby ensuring that its lower end stably protrudes from the outer shell of the support base 1 and remains in contact with the ground, so as to achieve effective grounding even in uneven ground environments.

[0030] To achieve a conductive connection between the barrel 2 and the grounding rod 10, a spring wire 8 is fixedly connected to the bottom end of each lower conductive strip 6. The other end of the spring wire 8 is fixedly connected to the middle of the grounding rod 10, and stable conductivity is achieved through elastic pressing.

[0031] Example 2

[0032] like Figures 1-4 As shown, the present invention proposes a chemical storage tank with anti-static function. Compared with Embodiment 1, this embodiment further includes: the tank cover 3 is a screw-on structure with a thread on the inner side of its lower end, which is screwed on to fit the threaded part on the outer wall of the top of the tank body 2. A paddle structure may be provided on the upper surface or side of the tank cover 3 to assist in tightening or loosening the operation.

[0033] A ring plate 4 is rotatably mounted on the lid 3. The lower surface of the ring plate 4 is uniformly inlaid with an upper conductive strip 5, which corresponds to the lower conductive strip 6 of the barrel body 2. The material can also be carbon fiber or graphite conductive sheet.

[0034] Specifically, the conductive sealing ring 7 is embedded in the lower surface of the ring plate 4 and fixedly set on the sealing contact surface at the joint position of the lid 3 and the body 2. It is preferably a conductive rubber ring containing carbon black or graphite powder. When the lid 3 is tightened, the conductive sealing ring 7 forms a three-point contact with the two contacts of the upper conductive strip 5 and the top contact of the lower conductive strip 6, so that a continuous low-resistance conductive closed loop path is established between the body 2 and the lid 3.

[0035] When in use, after the chemical liquid is injected into the inside of the barrel 2, the barrel cover 3 is tightened by the threaded structure. During the tightening process, the conductive sealing ring 7 is pressed against the opening at the top of the barrel 2. With its elasticity and conductivity, it makes full contact with the upper and lower conductive strips to complete the closure of the conductive path.

[0036] When the barrel 2 is placed on the ground, the grounding rod 10 compresses the support spring 9 and retracts upward under its own weight, so that the bottom end of the grounding rod 10 is in close contact with the ground to form a ground; at the same time, the static electricity inside the barrel 2 can be discharged through the lower conductive strip 6 → spring wire 8 → grounding rod 10 → ground, realizing a complete anti-static discharge path.

[0037] In summary, the structural design achieves electrostatic discharge and conduction functions without the need for electronic components, making it suitable for explosion-proof environments such as flammable and explosive materials. It features a simple structure, low manufacturing cost, and strong applicability.

[0038] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
