[0026] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] refer to Figure 1-4 , shows an isolation cover for discharging a filter press of the utility model, comprising a cover body, wherein the cover body is provided with:

[0028] A material inlet, which matches the outlet of the filter press;

[0029] A material discharge port, which is located on a side of the cover body adjacent to or opposite to the material access port, and a conveying pipe is installed at the material discharge port;

[0030] An operation port, which is located on a side of the cover body adjacent to or opposite to the material access port and is located on a different side from the discharge port, and a glove is installed on the operation port;

[0031] A tool port is located on the same side of, adjacent to or opposite to the material access port of the cover body, and a delivery tube is installed on the tool port.

[0032] In the utility model, after the material is filtered and dried, the material access port of the isolation cover is sealed and connected with the discharge port of the filter press to connect the isolation cover and the filter press for easy discharge in the isolation cover; the operator is outside the isolation cover, wearing gloves arranged at the operation port to perform the discharge operation; before the operation, the operating tool is first placed in the delivery tube, and during the operation, the operating tool is taken out of the delivery tube from the tool port, and the solid material is delivered from the discharge port of the filter press to the discharge port of the isolation cover by the operating tool, and the material is delivered to the collection device through the delivery pipe; the entire operation process is carried out in the isolation cover, the solid material is only dissipated in the isolation cover, and the odor is hardly diffused outside the isolation cover, which can avoid pollution to the working environment, effectively protect the health and safety of the operators, and can also effectively prevent foreign matter from the external environment from being introduced into the product. The utility model is detachably connected to the isolation cover, which is convenient for use and storage. It is preferably made of a transparent material (such as acrylic, etc.) to facilitate the operator to observe at all times during operation. If it is not desired to be restricted by this, for example, a non-transparent material can also be used. It is preferred to install a camera in the isolation cover, and the camera transmits the image information in the isolation cover to a position installed on the outer wall of the isolation cover and convenient for the operator to observe. Since it can be achieved through the existing technology, it will not be repeated here. It should be noted that the operating port and the discharge port of the isolation cover are not arranged on the same side to facilitate the operator to observe the discharge during operation and facilitate operation. The discharge port and the material access port are not arranged on the same side to facilitate the discharge operation of the operator; in addition, the utility model can use gloves made of nitrile rubber, for example. It should also be noted that the delivery tube adopts, for example, a self-sealing structure to prevent solid materials or odors from overflowing during the discharging process. After the material access port of the isolation cover is docked and installed with the discharge port of the filter press, the filter press is still in a closed state and the solid material is still in the filter press. At this time, the discharging tool is placed in the delivery tube, and then the delivery tube is sealed. After that, the discharge port of the filter press is opened to perform the discharging operation normally. The delivery tube can, for example, be a material with a certain flexible structure (such as polyethylene material, etc.), and the self-sealing structure can, for example, be a self-sealing strip arranged at the end of the delivery tube, which can be achieved through existing technology and will not be repeated here.

[0033] In a specific embodiment, a sealing ring is provided between the material inlet and the discharge port of the filter press. It is understandable that the addition of the sealing ring can effectively enhance the sealing between the filter press and the isolation cover, effectively prevent the solid material from overflowing, the odor from spreading, and effectively prevent foreign matter from the external environment from being introduced into the solid material.

[0034] In a specific embodiment, the material inlet is detachably mounted on the discharge port of the filter press. In this specific embodiment, the detachable connection method includes but is not limited to a chuck interface connection, a flange connection, a threaded connection, a fastener connection, and the like.

[0035] In a specific embodiment, the number of the operation ports is four, and two of the operation ports are respectively provided on two opposite sides of the cover body. Understandably, the operator preferably operates with both hands at the same time, and therefore, at least two operation ports are required on the same side, which is convenient for an operator to operate with both hands. Multiple operation ports can also be provided on the same side, so that multiple people can work together on the same side. Multiple operation ports can also be provided on different sides, preferably on two opposite sides, so that multiple operators can work together on different sides.

[0036] In a specific embodiment, the cover body is provided with a nitrogen access port for connecting a nitrogen pipeline. Preferably, the nitrogen access port is connected to the nitrogen pipeline via a quick-release connector. It is understandable that the nitrogen access port is provided to facilitate the provision of a nitrogen atmosphere into the isolation cover, and a quick-release connector is used for easy disassembly; the nitrogen pipeline can be provided directly by the factory service end, or it can be an external nitrogen bottle, etc.

[0037] In a specific embodiment, the cover body is provided with a vent, which is used to connect an exhaust pipeline. Preferably, the vent is connected to the exhaust pipeline via a quick-release connector. Understandably, the vent is used to balance the air pressure in the isolation cover, and a quick-release connector is used for easy disassembly.

[0038] In a specific embodiment, the material of the quick-release connector is selected from one of stainless steel, Hastelloy, titanium or polytetrafluoroethylene.

[0039] In a specific embodiment, the cover body has a hanging ear. It is understandable that the purpose of providing the hanging ear or a similar structure on the cover body is to fix the isolation cover and reduce the force at the material access port. For example, the isolation cover can be fixed to a support frame or other device through the hanging ear. This can be achieved through existing technology and will not be described in detail.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
