Description

Technical Field

[0001] The utility model relates to the technical field of hoppers, in particular to a leak-proof hopper. Background Art

[0002] A leakproof hopper usually refers to a device used to prevent material leakage during industrial production. This type of hopper is usually designed to have a sealing performance to prevent dust, liquid or granular materials from leaking out of the hopper, keeping the working environment clean and avoiding pollution to the environment or health hazards to workers.

[0003] Leak-proof hoppers may use different designs and materials to suit different industrial application scenarios. For example, for liquid materials, a sealed hopper made of corrosion-resistant materials may be used; for dust or granular materials, specially designed valves or sealing devices may be used to ensure that the hopper remains sealed during operation.

[0004] In some industries, such as chemical, food processing and pharmaceutical, leakproof hoppers are very important equipment, because these industries have very high requirements on the cleanliness and safety of the environment and workplace.

[0005] When the leak-proof hopper currently used is connected to a kettle for use, since the kettle has the function of stirring, most of the leak-proof hoppers are directly covered with a lid on the top to prevent splashing. However, this structure is too simple. When there is air pressure inside the funnel, the lid is easily impacted to open and fall off. For this reason, we have designed a leak-proof hopper to solve the above problem. Summary of the invention

[0006] The utility model aims to solve the shortcomings in the prior art and proposes a leak-proof hopper.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A leakproof hopper, comprising a hopper body mounted on a kettle cover, and further comprising:

[0009] A sealing cover is movably mounted on the top of the material body, and a sealing ring is provided inside the cover to fit the top of the hopper body;

[0010] A mounting piece, fixedly connected to the bottom of the hopper body and fixedly connected to the kettle cover;

[0011] A connecting chain, one end of which is fixedly connected to the upper outer side of the hopper body, and the other end of which is movably connected to the sealing cover with a counterweight structure;

[0012] The counterweight structure includes a connecting pin, a first limit block, a counterweight block and a sealing gasket. The sealing cover is provided with a through hole for sliding installation of the connecting pin. The sealing gasket is installed on the connecting pin above the sealing cover to form a seal on the through hole of the sealing cover after installation.

[0013] Preferably, the connecting pin is movably installed in the through hole in the middle of the sealing cover, the top of the connecting pin is fixedly connected to the first limit block, and the connecting pin extends to the bottom of the sealing cover and is fixedly connected to the counterweight block;

[0014] The sealing gasket is installed on the connecting pin between the sealing cover and the first limiting block, and the sealing gasket is a bowl-shaped structure with an opening downward.

[0015] Preferably, the sealing gasket is made of rubber material, and the middle part of the sealing gasket is sleeved on the connecting pin.

[0016] Preferably, a fixing pin inclined downward is connected to the outer side surface of the hopper body, and a second limiting block is connected to the bottom end of the fixing pin;

[0017] One end of the connecting chain is movably mounted on a fixing pin between the second limiting block and the hopper body, and the other end of the connecting chain is movably mounted on a connecting pin between the first limiting block and the sealing pad.

[0018] Preferably, sealing rubber rings are connected to both sides of the interior of the sealing ring, and the two sealing rubber rings are arranged to abut against the side surfaces of the hopper body after the sealing cover and the hopper body are installed.

[0019] Compared with the prior art, the beneficial effects of the utility model are:

[0020] 1. The sealing cover is connected to the hopper body by a connecting chain. When in use, the connecting chain can play a role of traction and limitation on the sealing cover, which can effectively prevent the sealing cover from falling due to impact.

[0021] 2. A counterweight is installed on the sealing cover, which can strengthen the pressure of the sealing cover on the top of the hopper body when the sealing cover is covered on the hopper body, and can produce a certain resistance to the air pressure impact of each part of the hopper body, reduce the opening of the sealing cover, and enhance the stability between the sealing cover and the hopper body.
