Description

Technical Field

[0001] The utility model relates to the technical field of pharmaceutical and chemical equipment, in particular to an isolation cover for oven shoveling. Background Art

[0002] In the production process of chemical products or medicines, operators are often required to manually remove materials when discharging from the oven.

[0003] In actual production, operators need to open the oven cover and use a material rake to shovel the material. During the shoveling process, dust and odor will inevitably be generated. When the dust is too large, it is not only detrimental to the physical and mental health of the operator, but also blocks the operator's vision and affects the shoveling operation. In addition, the odor of the material also affects the physical and mental health of the operator. At the same time, due to the open cover operation, it is easy to introduce foreign matter from the external environment into the material, resulting in cross contamination, which brings risks to product quality and production safety.

[0004] In the prior art, the common protection method is to have the operator wear goggles or masks, or use a simple isolation plate to block the material while scraping. However, goggles or masks cannot completely prevent the escape of material dust and odor, and the protection effect on the operator is poor, and it cannot prevent foreign matter from mixing into the product. Similarly, baffles and isolation plates cannot effectively prevent cross contamination, which will affect production efficiency and safety.

[0005] Therefore, there is an urgent need in the art for an isolation cover for oven unloading, which can be used for unloading operations during the solid material unloading process to protect operators from material dust and odor, while effectively isolating the product system from the external environment to avoid cross contamination, thereby improving production efficiency and product quality.

[0027] Embodiment 1

[0028] like Figure 1-4 As shown, this embodiment shows an isolation cover for oven stripping, including an isolation cover body, a docking port is provided on one side of the isolation cover body, the docking port is used to dock with the discharge port of the oven, and a sealing strip 7 is provided on the side where the docking port contacts the discharge port of the oven. The sealing strip 7 can improve the airtightness of the closed space formed by the isolation cover of this embodiment and the discharge port of the oven. The bottom of the isolation cover body is a stepped bottom surface, and the bottom layer of the stepped bottom surface is provided with a discharge port. In this embodiment, the stepped bottom surface is provided with two steps. A material rake accommodating cylinder 4 and an operating port are provided on the side of the isolation cover body opposite to the docking port, and an operating glove 5 is fixedly installed on the operating port. An inert gas inlet and outlet structure is also provided on one side of the isolation cover body, and a tool barrel 3 is provided on the side of the isolation cover body opposite to the inert gas inlet and outlet structure. The tool barrel 3 is a hollow cylinder, and the interior of the tool barrel 3 is connected to the interior of the isolation cover body. The tool barrel 3 is used to temporarily store the tools required for the stripping operation. Hanging rings 6 are provided on both sides of the top of the isolation cover body. The hanging ring 6 is convenient for fixing and installing the isolation cover body to meet the needs of scraping materials in different structures or different scenarios.

[0029] There are two operation ports, each of which is detachably mounted with an operation glove 5, which extends to the interior of the isolation cover body. The material of the operation glove 5 is one of nitrile rubber, terpolymer, polyvinyl chloride PVC, butyl rubber, polyvinyl alcohol PVA or natural rubber. The material of the operation glove 5 can be selected according to the working conditions, and has good acid and corrosion resistance and is degradable, which improves the environmental protection of the utility model.

[0030] The material rake accommodating tube 4 is a hollow cylinder, the interior of which is communicated with the interior of the isolation cover body, and is disposed between the two operating ports. The material rake accommodating tube 4 is used to accommodate the rake rod of the material rake. When the operator is scraping the material, the material rake is controlled to move forward and backward relative to the operator, and the material rake accommodating tube 4 allows the rake rod to have enough movable space when the material rake moves.

[0031] The inert gas inlet and outlet structure includes an inert gas inlet 1 and an inert gas outlet 2, and the inert gas inlet 1 and the inert gas outlet 2 are arranged on the same side of the isolation cover body. The inert gas inlet 1 and the inert gas outlet 2 are both quick connectors for inert gas, and the specification of the quick connector for inert gas is DN25. The material of the quick connector for inert gas is stainless steel. In this embodiment, the inert gas is nitrogen.

[0032] The materials of the isolation cover body, the tool tube 3 and the material rake accommodating tube 4 are all low-density polyethylene, and the isolation cover body, the tool tube 3 and the material rake accommodating tube 4 are integrally formed by hot-melt welding. The overall quality is low, and it is easy to make and use.

[0033] Specific implementation method: Connect the inert gas inlet 1 to the inert gas source. In this embodiment, nitrogen is selected as the inertization gas. Connect the docking port of the oven stripping isolation cover provided in this embodiment to the discharge port of the oven, press the sealing strip 7, and place the material receiving device below the discharge port opened at the bottom layer of the stepped bottom surface to form a relatively closed environment and wait for material collection. The tools used in stripping are placed in the tool barrel 3 for the operator to use. The operator puts his hand into the operating glove 5 and moves the material rake so that the material rake moves back and forth relative to the operator to turn the material over. The material falls into the material receiving device and the stripping is completed.

[0034] In summary, the use of the oven feeding isolation cover shown in this embodiment can not only prevent the escape of material dust and odor from causing physical harm to the feeding personnel, but also prevent foreign matter from the external system from entering the material product and causing cross contamination, thereby effectively ensuring production safety and product quality.

[0035] In summary, the above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope 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 protection scope of the present invention.
