Description

Mechanical seal with heating jacket for gum base stirring kettle

Technical Field

The utility model relates to a mechanical seal technical field, concretely relates to area adds mechanical seal for gum base stirred tank of heat jacket.

Background

The mechanical seal is a device which is used for preventing fluid leakage and is formed by keeping fit and relative sliding of at least one end surface perpendicular to the axis of the rotating shaft under the action of fluid force and the elasticity of the compensating mechanism and under the matching of auxiliary seal. For example, in equipment such as a centrifugal pump, a centrifugal machine, a reaction kettle, a compressor and the like, a circumferential gap exists between a rotating shaft and the equipment as the rotating shaft penetrates through the inside and the outside of the equipment; when the rotating shaft rotates relative to the equipment, the medium inside the equipment can leak outwards through the circumferential gap; if the pressure inside the apparatus is lower than atmospheric pressure, air will flow into the apparatus and a sealing means against leakage is necessary.

The base stirring kettle is sealed by using a filler, so that the leakage amount is large, the environment is polluted, and the production is influenced. Gum base can solidify when low temperature, makes mechanical seal's quiet ring block, loses the compensation performance to lead to leaking, in order to solve above-mentioned problem, the utility model discloses a take heating to press from both sides mechanical seal for gum base stirred tank of cover.

Disclosure of Invention

To the not enough that exists on the prior art, the utility model aims to provide a take mechanical seal for gum base stirred tank that heating jacket uses this device under the prerequisite that does not change equipment, makes equipment reach zero leakage, promotes user's use and experiences, environmental protection, reduce cost.

In order to achieve the above purpose, the present invention is realized by the following technical solution: the utility model provides a take gum base stirred tank of heating jacket to use mechanical seal, includes the pivot, embraces the cover tightly, rotating ring seat, rotating ring, quiet ring, spring, flange and heating jacket, and the flange passes through the bolt fastening on the pump cover, and the pin that quiet ring passes through the throw-out collar is fixed on the flange, and the rotating ring seat is fixed in the pivot through embracing tightly the cover, and the rotating ring passes through the pin to be fixed on the rotating ring seat, and the spring promotes the laminating of quiet ring on the rotating ring, and the flange outside is provided with the heating jacket, and the heating jacket cup joints with the pivot.

Preferably, the first O-shaped ring is arranged at the matching part of the movable ring seat, the movable ring and the rotating shaft.

Preferably, two second O-rings are arranged at the matching part of the flange and the static ring.

Preferably, the spring is arranged at the atmosphere end and is not in contact with the gum base, so that the influence of the gum base on the spring is reduced.

The utility model has the advantages that: the utility model has the advantages of reasonable design, under the prerequisite that does not change equipment, set up a heating jacket, through applying hot-air, around the heat seal, make gum base keep mobility, let the compensation that quiet ring can be normal, use this device, make equipment reach zero leakage, promote user's use and experience, environmental protection, reduce cost.

Drawings

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments;

fig. 1 is a schematic structural diagram of the present invention.

Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

Referring to fig. 1, the following technical solutions are adopted in the present embodiment: the utility model provides a take gum base mechanical seal for stirred tank of heating jacket, including pivot 1, hold tightly cover 2, rotating ring seat 3, rotating ring 5, quiet ring 6, spring 7, flange 9 and heating jacket 10, flange 9 passes through the bolt fastening on the pump cover, quiet ring 6 is fixed on flange 9 through the pin of throw-out collar, rotating ring seat 3 is fixed on pivot 1 through holding tightly cover 2, rotating ring 5 is fixed on rotating ring seat 3 through the pin, spring 7 promotes the laminating of quiet ring 6 on rotating ring 5, the flange 9 outside is provided with heating jacket 10, heating jacket 10 cup joints with pivot 1.

It is worth noting that the first O-ring 4 is arranged at the matching position of the movable ring seat 3, the movable ring 5 and the rotating shaft 1.

It is noted that two second O-rings 8 are arranged at the matching position of the flange 9 and the static ring 6.

In addition, the spring 7 is arranged at the atmosphere end and is not in contact with the gum base, so that the influence of the gum base on the spring is reduced.

The mechanical sealing principle of the present embodiment: the flange passes through the bolt fastening and covers at the pump, and the quiet ring is fixed on the flange through the pin of push ring, makes it can not rotate, and the rotating ring seat is fixed in the pivot through holding the cover tightly, and the rotating ring passes through the pin to be fixed on the rotating ring seat, follows the rotating ring seat and rotates with the pivot together, and the spring promotes the quiet ring laminating on the rotating ring. The device is provided with a heating jacket, hot air is applied to heat the periphery of the seal, so that the gum base keeps fluidity, and the static ring can normally compensate; the mechanical sealing spring is arranged at the atmosphere end and is not in contact with the rubber base, so that the influence of the rubber base on the spring is reduced.

The basic principles and the main features of the invention and the advantages of the invention have been shown and described above.
