WATER COOLEID CONVEYOR CHUTE Filed Sept. 14, 1953 William A. Harrison INVENTOR.

BY WWW United States Patent WATER COOLED CONVEYOR CHUTE William A. Harrison, Carlsbad, N. Mex. Application September 14, 1953, Serial No. 379,778 1 Claim. (Cl. 193-38) This invention relates to mining equipment and more particularly to a new and novel conveyor especially adapted for conveying potash ore.

The primary object of this invention resides in the provision of a conveyor for potash ore adapted to be cooled by a water circulating system associated therewith so as to prevent hot potash ore passing therethrough from sticking to it and clogging the passages thereof.

Another object of this invention resides in the provision of a water cooled conveyor for potash ore adapted to permit the ore to pass through it without clogging and thereby require no loss of operation due to the time necessary for scraping the conveyor thereby eliminating the necessity for cleaning the side wall passage and thus saving the cost of labor now required to perform such tasks.

Still further objects and features of the invention reside in the provision of a water cooled conveyor that is strong and durable, simple in construction and manufacture, capable of being readily constructed out of convenient and suitable materials, and which requires only minor attention and maintenance.

These, together with the various ancillary objects and features of the invention which will become apparent as the following description proceeds, are attained by this water cooled conveyor chute, a preferred embodiment of which has been illustrated in the accompanying drawings, by way of example only, wherein:

Figure l is a perspective view of the water cooled conveyor chute comprising the present invention;

Figure 2 is a top plan of the conveyor chute;

Figure 3 is a vertical, sectional view as taken along the plane of line 3-3 in Figure 2 and illustrating the construction of the cooling passages in greatest detail;

Figure 4 is a vertical, sectional view as taken along the plane of line 44 in Figure 2 and illustrating the construction of the inlet and outlet connections for the water cooling system; and

Figure 5 is a sectional detail view as taken along the plane of line 5-5 in Figure 2.

With continuing reference to the accompanying drawings wherein like reference numerals designate similar parts throughout the various views, reference numeral generally designates the elongated metallic water cooled conveyor chute comprising the present invention. This conveyor chute is formed from an elongated channelshaped member 12 provided with a bottom or lower plate 14 and upwardly extending side walls 16 and 18. Anchor holes as at 20 are formed in the bottom or lower plate 14 and are provided for more easily attaching the conveyor chute to a platform or other apparatus as may be desired.

Secured to the side walls 16 and 18 in spaced relation relative to the lower plate 14 is an upper plate 22 which terminates as at 24 inward from one end of the channelshaped member 12 to thereby form a platform 25 at one end of the conveyor chute 10. End walls 26 and 28 are secured to the upper plate 22 and the lower plate 14 and extend between the side walls 16 and 18 to thereby form a closed water cooling chamber 30. It is to be noted that the side walls 16 and 18 extend upwardly above the upper plate 22.

Extending between the upper plate 22 and the lower plate 14 and secured to the end wall 24 and extending almost to but terminating short of the end wall 28 is a partition 32 adapted to form a maze for the fluid as it passes into the water inlet connection 34 and from the water outlet connection 36 disposed at opposite ends of the maze so formed. Connected to the water inlet and outlet connections 34 and 36 are inlet and outlet hoses 38 and 40 which are connected to a cold Water supply system, not shown, so as to circulate the water through the chamber during operation of the conveyor and thereby prevent hot potash from sticking to the walls of the conveyor thereby increasing the efficiency of the ore mill.

From the foregoing it is to be understood that the hot potash ore is carried along the upper plate 22 between the side walls 16 and 18. The cooling fluid prevents the sticking of the ore to the chute as would otherwise occur and thereby it may be more easily processed. Accordingly, since the invention may be readily understood from the foregoing, further description is believed to be unnecessary.

However, since numerous modifications will readily occur to those skilled in the art, after a consideration of the foregoing specification and accompanying drawings, it is not intended to limit the invention to the exact embodiment shown and described, but all suitable modifications and equivalents may be readily resorted to.

What is claimed as new is as follows:

A water cooled conveyor chute comprising an elongated body portion of substantially channel shape in cross-section and having anchor holes adjacent one end thereof, an elongated water circulating chamber formed between the sides of the body portion of the conveyor with the first end of said chamber adjacent said anchor holes terminating inwardly of said anchor holes, an elongated partition extending centrally through the water chamber, said partition having a water passage therethrough at the other end of said chamber, said partition dividing said water chamber into opposed sides, a water inlet conduit secured to said chamber communicating with one side of said chamber, and a water outlet conduit secured to said chamber, communicating with the other side of said chamber, said conduits being disposed at the first end of said chamber opposite the other end of said chamber having the water passage therethrough.
