[0006] Although this adverse wedging effect occurs infrequently and when it does occur, even temporarily, it is likely to be different for different types of material being processed, but its impact on accuracy and feeding performance is unacceptable degree
Because, the tendency of equipment to stop due to this wedging - temporarily or for a long time - will be greater at high speeds of equipment, slow down the equipment in order to reduce the possibility of material wedging, although it may reduce the risk of wedging. possibility, but this is also unacceptable

[0034] Such as image 3 As shown, it is a schematic diagram of the relationship between the drive disc 24 and the inner wall 16 of the housing 10, the distance between the peripheral edge of the drive disc 24 and the inner wall 16 of the housing 10 is along the direction of rotation of the drive rotor 18, from The inlet 12 of the housing 10 increases gradually to the outlet 14 of the housing 10, which in the illustrated and described embodiment of the invention is clockwise as indicated by the arrows. The drive platter 24 and the inner wall 16 of the housing 10 can be shaped in different ways to provide the required space between the two components. For the illustrated and described embodiment of the invention, the drive platter 24 is circular and extends away from the hub 20 perpendicular to the axis of rotation 22 of the hub 20 and the inner wall 16 of the housing 10 is helical. The helical inner wall 16 of the housing 10 can be defined by the Archimedes screw equation:

[0047] In the second embodiment of the present invention, as Figure 6 and 7 As shown, a low friction brush seal 50 is disposed on the periphery of the drive platter 24 . The brush seal 50 can be fabricated from a variety of different materials including, for example, pipe cleaners and rope. The brush seal 50 can also be manufactured by combining a base made of a metal such as carbon steel, stainless steel or aluminum with a non-metallic brush made of natural or synthetic rubber.

[0048] It is not necessary for the brush seal 50 to form a complete seal between the periphery of the drive platter 24 and the inner wall 16 of the housing 10 . Although a small amount of contact may occur between the brush seal 50 and the inner wall 16 of the housing 10, the brush seal 50 causes little or no contact between the drive platter 24 and the housing 10 as the drive platter 24 rotates. The friction between the inner walls 16. Low friction seals are important to avoid excessive loads o...

[0057] In the third embodiment of the present invention, as Figure 8 9, a third form of material scraper 56 is provided. Such as Figure 8 As shown, the material scraper 56 can have a continuous scraping surface 40, such as Figure 5 Material scraper 36 in. Alternatively, as shown in FIG. 9, the material scraper 56 may have multiple scraping tips 26a, 26b, and 26c, such as Figure 4 The material scraper 26 shown in.

[0058] The function of the material scraper 56 is to scrape the material being processed by the bulk material pump off the drive platter 24 and hub 20 as the material exits the bulk material pump. For many materials, this scraping is unnecessary. The material scraper 56 is particularly suitable for those applications where no or only minimal scraping is required. Specifically, compared to Figure 4 The material scraper 24 and Figure 5 The material scraper 36 of the material scraper, the main structure forming the material scraper 56 has been removed (as...

Abstract

A bulk materials pump feeder having a housing and a rotating drive rotor for transferring material from an inlet to an outlet of the housing. The drive rotor has a hub. Drive disks extend away from the hub toward a housing inner wall and have a compliant edge configured to deflect or compress when presented with pinched material rather than jamming.

Description

[0001] This application is incorporated by reference to U.S. Patent No. 7,044,288, filed May 16, 2006, by inventors Timothy R. Baer and James T. Foley, entitled "Bulky Material Pump with Disc Plugging Reduction" and by inventor Timothy R. Baer and James T. Foley. U.S. Patent No. 6,832,887, filed December 21, 2004, to R. Baer and James T. Foley, entitled "Bulky Material Pump," and filed October 12, 2005, entitled "Disc Blockage-reduced bulk material pump, flexible disc" US Patent Application No. 60 / 726,340, and all other references cited herein. technical field [0002] The present invention relates generally to material handling equipment and, in particular, to a pump for material handling equipment that feeds bulk material. Background technique [0003] In some material handling equipment, such as those described in U.S. Patent No. 5,051,041 and U.S. Patent No. 5,355,993, a pump moves bulk material through a housing from an inlet to an outlet by rotating a drive rotor havin...
