Abstract

The invention discloses a clean type pneumatic conveying shield, which comprises a shield body for picking up puffed material from an puffed discharge port and pneumatically conveying it to the next process and having a hollow and sealed inner cavity, located in the middle of the top of the shield body And the outlet pipe communicated with the inner cavity of the shield and at least two inlet pipes respectively located on the top of the shield body around the outlet pipe and communicated with the inner chamber of the shield, the shield body is provided with a connection with each inlet pipe Corresponding and rotatable diverter plates, an upper partition above each diverter plate and a lower partition below each diverter plate. The one-piece shield body design of the present invention greatly reduces the number of connection points on the sealing surface, thereby reducing the occurrence of leakage and contamination, and the shield body equipped with an inspection door can be easily and quickly accessed 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 ...

Embodiment Construction

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

[0052] Such as figure 1 , figure 2 , image 3 with 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 co...
