Abstract

The invention discloses a cleaning type pneumatic conveying protective cover which comprises a protective cover body, an outlet pipeline and at least two inlet pipelines. The protective cover body isused for picking bulked materials from a bulking discharge port and pneumatically conveying the bulked materials to a next process and is provided with a hollow closed inner cavity, the outlet pipeline is positioned in the middle of the top of the protective cover body and communicates with the inner cavity of the protective cover, and the at least two inlet pipelines are respectively positioned on the top of the protective cover body, are arranged around the outlet pipeline and communicate with the inner cavity of the protective cover. Rotary splitter plates in one-to-one correspondence withthe inlet pipes, upper partition plates located above the splitter plates correspondingly and lower partition plates located below the splitter plates correspondingly are arranged in the protective cover body. Due to the integrated protective cover body design, the number of connecting points on a sealing surface is greatly reduced, leakage and pollution are reduced, and the protective cover bodyprovided with an overhaul door facilitates convenient and rapid entering for cleaning, template replacement and other maintenance.

Description

technical field

[0001] The invention relates to a pneumatic conveying shield, in particular to a clean pneumatic conveying shield and an extruder mold replacement system and replacement method. Background technique

[0002] The extruder pneumatic conveying shield is a device that picks up the extruded products in the extruder and transfers them to the pneumatic conveying system, in which the pneumatic conveying system can transfer the products to the next process through air, pipelines and separation equipment. Previous pneumatic conveying enclosures have drawn untreated air in situ at the installation location into the ducts, usually from the ground. Design trends in recent years have introduced positive pressure air into a closed-loop piping system and recycled system hot air to avoid microbial contamination of the product.

[0003] The existing technology has developed a further design to allow easier access to the inside of the hood for cleaning and maintenance, and at ...

Examples

Embodiment Construction

[0051] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0052] like figure 1 , figure 2 , image 3 and Figure 4 As shown, a clean pneumatic conveying shield of the present invention includes a shield body 1, an outlet pipe 2, an inlet pipe 3, a splitter plate 4, an upper partition 5, a lower partition 6, a discharge port 7, and a discharge door 8. Arc partition 9, top hinged access door 10, bottom hinged access door 11, hinged formwork access door 12, rotary actuator 13, spring return sampling door 14, clamp seal assembly 15 and adjustable Seal assembly 16.

[0053] The shield body 1 is an integral structure. The shield body 1 is used to pick up the puffed material from the puffed discharge port and convey it to the next process by pneumatic force. The shield body has a hollow and sealed inner cavity. One side of the shield body 1 It is connected to the extruder, and the other side is connec...
