Filed May 8, 1953 June 15, 1954 APPARATUS FOR AND CONDITIONING OF PAPE Patented June 15, 1954 2,680,997 APPARATUS FOR CONTINUOUS CHEIWICAL CLEANING AND MILL WET FELTS CONDITIONING OF PAPER Dudley A. Huber, Toccoa, Ga. Application May 8, 1953, Serial No. 353,729
1 Claim. 1
This invention relates to chemical means and system for continuous wet felt cleaning and conditioning.
My co-pending application, Serial No. 176,775, filed July 29, 1950, now abandoned, for a composition for lengthening the life of paper mill wet felts discloses a composition which contains a detergent agent and a bactericide, and where desired, a disbursing agent. This composition greatly prolongs the useful life of felts, more particularly wet felts such as are used in paper mills.
It is accordingly a principal object of the present invention to provide apparatus and a system for continuous chemical cleaning and conditioning of paper mill wet felts using the prod uct disclosed in the aforesaid pending application.
It is another object of the present invention to provide a system for applying my product which has many advantages over the mechanical means now employed for cleaning and conditioning of wet felts, the actual life of the Wet felts in some instances being doubled by application of the present system.
For other objects and a better understanding of the invention, reference may be had to the following detailed description taken in connection with the accompanying drawing, in which the figure is a diagrammatic view showing the process and apparatus embodying the features of the present invention.
Referring now more in detail to the drawing, there is shown a drum l containing my improved product and connected to a proportioning pump 5! by means of flexible tubing I2, substantially as illustrated.
A continuous supply of water is supplied to the pipe 3 at 40 to 60 pounds per square inch, a shut off valve it being provided in pipe it. The pipe it connects with Monel filters l5 and I6 (100 mesh) by means of branch pipe lines ll and 8 respectively. Valve I9 is provided in branch line H while valve is provided in branch line i 8. The filters l5 and i6 connect with the main pipe line 2i by means of branch pipes 272 and 23 respectively, valve 24 being provided in branch pipe line 22 and valve 25 being provided in branch pipe line 23.
A pressure control valve 26 is provided in pipe line 2! (15 to 20 pounds per square inch). The main pipe line 52! connects when the first press shower 2?, the second press shower 28 and the third press felt or pick up felt shower 29, disposed over wet felts 30, 3! and 32, respectively.
- other terminal of pressure trough 33 being connected to one terminal of proportioning pump l i by means of a wire 35. The other terminal of proportioning pump H is connected to power terminal B by means of a wire 36.
A pressure gauge 3! is provided in pipe line 2i intermediate valve 26 and pressure trough 33. A measuring device 33 is provided intermediate the pump H and pipe is. The compound passes from drum it through tubing l2 into proportioning pump H where it passes into pipe l3 by means of tubing 39.
A saving in both steam and electricity has been obtained using the above system and apparatus. Suction presses have been kept in a more satisfactory condition as regards plugging and sliming. The system, it will be noted, uses a spray across the width of the wet felt. The above system and equipment supplies the correct proportion of the compound as a solution to the sprays and at the proper pressure. The pressure trough cuts out the pump II when the Water pressure falls below that necessary to operate the sprays. From one-half to one pound of the compound (Feltex) is fed into the system per hour, depending upon the condition and type of machine.
It should be apparent that there has been provided a chemical means and system for continuous wet felt cleaning and conditioning. The measuring device 38 measures and records the flow of compound to the system.
Tests with the above system and apparatus have shown that savings of $150.00 per day can be made in paper mills.
In operation, the incoming Water, controlled by valve M, passes through pipe I3 where it is mixed with the compound from tubing 39 delivered from the drum l0 by the pump ll, passing through the gauge 38. The solution then courses through filters l5 and I6 and into the main line 2! through the pressure control valve 3'5. The solution is then delivered on the wet felts from the sprays or showers 21, 28 and 29, providing a means and system for continuous Wet felt cleaning and conditioning.
While various changes may be made in the detail construction, it shall be understood that such changes shall be within the spirit and scope of the present invention, as defined by the appended claim.
Having thus set forth and disclosed the nature of my invention, what is claimed is:
Apparatus for continuous chemical cleaning and conditioning of paper mill wet felts comprising a plurality of press showers connected to a continuous source of water, a reservoir of a conditioning compound, pumping means connected with said reservoir for delivering said conditioning compound into the water line connecting with said press showers, filtering means in the system intermediate the introduction of the compound and said press showers, and means for turning off said pumping means when the wa ter pressure falls below that necessary to operate the said press showers, and comprising a pressure trough connected to the said water line and electrical means for controlling the said pumping means, the latter comprising a proportioning pump, tubing connecting the latter with the said reservoir and tubing connecting the said proportioning pump with the said Water line, and the said press showers extending across the width of the wet felts and including a first press shower, a second press shower and a third press felt or pick-up felt shower, the said filtering means comprising a pair of Monel filters connected with the said water line in parallel, valves disposed on each side of the said filters, a shut-01f valve provided in the said water line at the entry side of the said filters, a second valve provided on the other side of the said filters, a pressure control valve, and a pressure gauge extending from the said water line, and a measuring device disposed intermediate the said proportioning pump and the inlet point of the said compound into the said apparatus.
