[0017] The utility model is further described below in combination with the drawings and embodiments, these drawings are all simplified schematic diagram, just with the schematic way the basic structure of the utility model is explained, therefore it just shows the constitution related to the utility model.

[0018] It needs to be explained, if the embodiment in this embodiment has the directionality indication (such as upper, lower, bottom, top etc.), then the directionality indication is only used to explain the relative position relationship, movement condition etc. between components in a certain specific posture, if the specific posture changes, then the directionality indication also changes accordingly. The term 'first','second' is only for the purpose of description, and can not be understood as indicating or implying the relative importance or implicitly indicating the number of indicated technical features. Therefore, the features limited by 'first','second' can explicitly or implicitly include one or more features. Unless otherwise specified and limited, the terms'set', 'connected', 'connected' should be understood broadly, for example, can be fixedly connected, can be detachably connected, or integrally connected;It can be directly connected, or indirectly connected through an intermediate medium, or the communication between two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0019] As Figures 1-2As shown, an annular gas cover for a dispersion machine comprises a cover shell with a sealed gas cavity 101 built-in, the cover shell is annular and can be arranged around the outer periphery of the cylinder cover of the dispersion machine; wherein the cover shell is provided with a gas hole 102 and a connector 103 in communication with the sealed gas cavity 101, and the sealed gas cavity 101 can be connected to negative pressure gas through the connector 103.

[0020] Specifically, the annular cover shell has a small volume and can be directly placed on the cylinder cover of the dispersion machine. At the same time, the sealed gas cavity connected to the negative pressure gas through the connector 103 can form an annular negative pressure area around the gas hole 102, so that when the volatile gas is volatilized from the edge of the cylinder cover, the volatilized matter can be directly blocked by the negative pressure area formed around the outer periphery of the cover shell and collected into the sealed gas cavity 101, until the volatile gas is transferred to other links for treatment or recycling through the connector 103. Compared with direct air extraction, the negative pressure area formed by the negative pressure gas is more gentle in treating volatile gas and will not exacerbate the volatilization of organic matter.

[0021] At the same time, in the technical solution, the pressure of the negative pressure gas can be accurately regulated by a pressure regulating valve, so that the volatilization speed of the organic matter can be stably maintained within a certain range, reducing the waste of resources.

[0022] As shown above, Figure 2 The cover shell comprises a first shell 1 and a second shell 2 embedded on the first shell 1, and the first shell 1 and the second shell 2 form a sealed gas cavity 101. The cover shell adopts a split structure design, the structure is clear, and the manufacturing cost is low.

[0023] Further, as shown above, Figure 2 In order to facilitate the daily maintenance and cleaning of the first shell 1 and the second shell 2, the inner side of the first shell 1 is provided with a rib 3 for supporting the second shell 2, and the edge of the first shell 1 is provided with a plurality of crimping flanges 4, which can be bent to abut against the second shell 2 to fix the second shell 2 on the first shell 1, facilitating operation.

[0024] As mentioned above, a sealing gasket 5 is arranged between the first shell 1 and the second shell 2 to increase the sealing of the connection between the first shell 1 and the second shell 2.

[0025] In the technical solution, as shown above, Figure 1 The gas holes 102 can be arranged in a circumferential array on the first shell 1 or the second shell 2, which can be selected according to the working environment, and has high flexibility.

[0026] Further, in order to increase the service life of the cover shell, the inner side of the sealed gas cavity 101 is coated with a corrosion-resistant coating, i.e. a corrosion-resistant material is coated on the first shell 1 and the second shell 2, and the corrosion-resistant material adopts existing technology and can effectively resist the corrosion of organic volatile gas.

[0027] Working principle: through the joint 103 access negative pressure gas sealed cylinder, can overflow gas hole 102 in the cylinder cover around the area to form a ring negative pressure area, so that the volatile gas from the cylinder cover edge out volatile, volatile can be directly blocked and collected to the sealed gas cavity 101 in the negative pressure area formed by the shell circumference, until the volatile gas from the joint 103 to other links for processing or recycling. Compared with direct exhaust, the negative pressure area formed by the negative pressure gas is more gentle in processing volatile gas, and will not exacerbate the volatilization of organic matter.

[0028] The above is based on the ideal embodiment of the present application, through the above description, relevant personnel can make various changes and modifications without deviating from the technical idea of the present application. The technical scope of the present application is not limited to the content of the specification, and the technical scope must be determined according to the scope of claims.
