Description

Apparatus for casting an activated charcoal with high water content rate

The present invention relates to a device for inputting activated carbon for water treatment, and more specifically, high moisture content activated carbon which enables continuous dissolution and supply of activated carbon having a high moisture content (water content of 30% or less) without generation of agglomeration and cavitation It relates to an input device.

In general, the treatment of activated carbon is volatile organic compounds such as taste, odor-causing substances synthetic detergents, phenols, trihalomethane and its precursors, trichloroethylene, etc. which are not removed by normal water treatment such as flocculation, precipitation and filtration. This is to remove trace harmful substances such as chemical substances, other organic matters, etc. temporarily introduced due to accidents in the upstream water source.

In addition, the activated carbon is processed by a separate activated carbon input device, and is supplied in powder or wet form. However, in the case of powdered activated carbon, the powder is blown when added, and water is supplied to prevent dispersion of the powder. Additional equipment of the device is required, and wet type activated carbon having a moisture content hardens or aggregates during storage in a hopper, and also causes a problem that a smooth supply is impossible due to the occurrence of a hole phenomenon.

Therefore, the development or improvement of activated carbon input device to enable the smooth supply of activated carbon without problems caused by the supply of the powder and wet activated carbon will be referred to as a priority. Although many have been developed, these structures also cause various structural problems as pointed out below.

First, the activated carbon input device of Utility Model Registration No. 171842, which is assigned to a domestic storekeeper, is configured to automatically input wet and activated lime and activated carbon having a water content of 50% to purify the dust by slaked lime and activated carbon. Although it is a structure for preventing occurrence, there are structural problems as follows.

First of all, the pre-registration devises that the stirring rod of the stirrer installed in the storage hopper is horizontally installed only near the inner wall of the hopper with respect to the rotation axis, so that it is impossible to prevent the cavitation of the inside of the hopper, for example, the stirring rod does not reach. This is not going well.

Secondly, the pre-registration proposal is that there is a problem that the wet activated carbon is agglomerated at the lower end of the hopper because the stirring rod is not connected to the bottom of the storage hopper.

And thirdly, the lower part of the storage hopper installs a grinder for pulverizing aggregated lime or activated carbon to the lower part of the storage hopper, which can be installed with a plurality of grinding blades and can be rotated together with the lower feed screw. There is a structural complexity that must be done.

In addition, the fourth preliminary registration plan is to install only the transfer screw inside the transfer cylinder to transfer the wet slaked lime or activated carbon that was crushed and dropped from the grinder to one side. There is a problem that supply of a quantity of activated carbon becomes impossible by generating a bridge phenomenon.

Therefore, the above-mentioned pre-registration proposal is not only difficult to supply quantitatively due to wet hydrated lime, which has a high water content, cavitation and coalescence of activated carbon, and sticking to the wall of the transfer cylinder, but also can not be injected quickly. There is a problem that the driving efficiency is reduced by that much.

On the other hand, the solid treatment agent for water treatment of Korean Utility Model Registration No. 259021 granted to Incheon Waterworks Headquarters and Hanhim Technology Co., Ltd. is a solid powder or powder for water treatment in a hopper equipped with a vibrator and a dust removal dust collector. Activated carbon and slaked lime), and through the screw conveyor installed under the storage hopper to quantitatively supply the solid chemicals into the dissolution tank and to supply the purified water through the purified water supply pipe to the injection pipe installed in the dissolution tank, One design is that the dust collector is installed in the hopper, and the discharge wing structure installed in the hopper is suitable for the quantitative input of solid particles or powdered solid powder chemicals, and not for the injection of wet chemicals having high moisture content. Even if it applies to wet chemicals In this case, there is a structural limitation that it is impossible to prevent cavitation or agglomeration of wet chemicals in the hopper and sticking to the inner wall of the cylinder in which the screw conveyor is installed. For example, an injector designed to be applicable to the input of a dry drug is not very suitable for the input of a wet drug and causes many problems in efficiency of operation and operation of the machine.

Therefore, the present invention was devised to solve such problems in the related art, and an object of the present invention is to prevent cavitation or agglomeration in the hopper due to the input of activated carbon having a high moisture content, so that activated carbon is always smoothly injected. In addition, it is to provide a high moisture content activated carbon input device that maximizes the activated carbon storage efficiency by maximizing the amount of activated carbon stored in the screw feeder at all times.

As shown in FIG. 4, the hopper activated carbon input monitoring window 70 is installed between the rotary valve 50 and the screw feeder 60 to operate the rotary valve 50 and the activated carbon introduced from the hopper 10. In order to monitor the state of, this is made of a structure in which the transparent acrylic tube 71 is fixed by the stainless band 72, but is not necessarily limited to this in design.

On the other hand, according to the present invention, as the screw feeder 60 is further provided with a screw feeder activated carbon input monitoring window 80 as shown in Figure 5 to check the activated carbon introduced into the dissolution tank 90 from the screw feeder 60 and the screw ( It is preferable to facilitate the cleaning of the activated carbon attached to 64.

6 is a view schematically showing the structure of the control panel 100 according to the present invention, which is a weight reduction for controlling the continuous input of activated carbon and the amount of activated carbon in accordance with the amount of activated carbon reduced in the raw water flow rate and the hopper 10 The controller 101, the rotation speed controller 102 for controlling the rotation speed of the control motor, and the operating time of the rotary valve 50 to control the amount of activated carbon to be introduced into the screw feeder hopper 61 In addition to the rotary valve operation time setting regulator 103, various switches required for operation of the input device are provided.

In Fig. 1 and Fig. 2, reference numeral 30 denotes a load cell for measuring the reduced amount of activated carbon stored in the hopper 10.

When explaining the high moisture content activated carbon input state using the input device of the present invention configured as described above, first the input port 11 is stored in the activated carbon having a high moisture content in the hopper (10). When operating the corresponding switches of the control panel 100 in this state, the activated carbon pulverized evenly by the grinder 20 in the hopper 10, the operation of the rotary valve 50, the screw 64 of the screw feeder 60 The wet activated carbon is introduced into the dissolution tank 90 in an appropriate amount, and dissolved in the dissolution tank 90 by the admixture 92 rotated by the motor 91. At this time, when the activated carbon is added, the hopper 10 The empty gate 40 connected to the bottom of the position is of course adjusted to the open state by the handle operation.

Meanwhile, in the present invention, the activated carbon in the hopper 10 that is crushed by the operation of the grinder 20 has one end fixed by the bearing 24 of the support 23 by the driving of the motor 22 connected to the reducer 21. By simultaneously rotating the support rod 26, the main grinding rod 27, and the auxiliary grinding rod 28 along the rotating shaft 25, the moist activated carbon stored in the hopper 10 is crushed as a whole.

For example, the inner circumference of the hopper 10 is crushed by the main grinding rods 27 horizontally installed to its proximal position, and the inner central portion in which the rotating shaft 25 is installed is connected to the main grinding rods 27 respectively. (28), and the space therebetween is crushed by the support rods 26 installed in a spiral, so that the wet activated carbon stored in the hopper 10 is crushed evenly without being biased, thereby causing cavitation or agglomeration. It is possible to prevent the occurrence of the hopper 10 to be smoothly transported.

In addition, the activated carbon having a high moisture content supplied from the hopper 10 to the rotary valve 50 passes through the lower end of the hopper 10 and the inside of the empty gate 40, but is supplemented with an auxiliary grinding rod of the rotating shaft 25 installed therein. As the continuous grinding is made by 28, the activated carbon transferred to the lower end of the hopper 10 is also agglomerated or prevented from occurring.

The activated carbon pulverized and supplied from the hopper 10 passes through the empty gate 40 and passes through the rotary valve 50 again into the screw feeder hopper 61 of the screw feeder 60 installed at the bottom thereof in a state where aggregation is prevented. The activated carbon supplied into the screw feeder hopper 61 is quantitatively introduced into the dissolution tank 90 located below through the screw 64 rotated by the rotation speed control motor 62, wherein the screw The wet activated carbon introduced into the dissolution tank 90 through the 64 is prevented from solidifying by the heater 63 so as not to stick to the screw 64, and the activated carbon stored in the screw feeder hopper 61 is transferred to the outside thereof. The bridge phenomenon is prevented by vibrating operation of the installed vibrator 65, so that smooth injection into the dissolution tank 90 is possible.

On the other hand, the operating state of the activated carbon supplied from the hopper 10 to the screw feeder 60 can be confirmed by the operator through the hopper activated carbon monitoring window 70, and also through the screw feeder activated carbon input monitoring window 80 Since the activated state of the activated carbon introduced into the dissolution tank 90 from the feeder 60 can be checked and appropriately controlled, the activated state of the activated carbon can be properly adjusted, and in particular, the wet activated carbon in the screw 64 of the screw feeder holder 61 In the case of sticking, cleaning through the check cover 81 becomes possible, and maintenance is very convenient.

Therefore, the present invention is the molten bath 90 through the empty gate 40, rotary valve 50 and screw feeder 60 while the wet activated carbon is continuously dissolved by the grinder 20 in the hopper 10 through the above process. It is to be continuously supplied in quantitatively by) so that the continuous dissolution of activated carbon in the dissolution tank 90 is possible.

On the other hand, when the activated carbon stored in the hopper 10 is reduced, a certain amount of activated carbon is always filled and controlled by the detection of the load cell 30 connected to the weight sensing controller 101 of the control panel 100.

In addition, the rotation speed control motor 62 of which the rotation speed is controlled by the rotation speed controller 102 and the rotary valve operation time setting controller 103 of the rotary valve 50 and the screw feeder 60 whose operation time is adjusted Due to the interlocking operation of the paddle level switch 66, a predetermined amount of activated carbon can always be introduced into the screw feeder hopper 61.

For example, when a certain amount of activated carbon is filled into the screw feeder hopper 61 by the paddle level switch 66, the supply of activated carbon is stopped from the hopper 10, and when it is insufficient, the grinder 20 is removed from the hopper 10. ) And the rotary valve 50 is interlocked to control the supply of activated carbon smoothly.

In the maintenance of the screw feeder 60, the lower movement of the activated carbon stored in the hopper 10 is stopped by closing the empty gate 40 in the open state.

According to the present invention as described above, even if the activated carbon having a high moisture content according to the water treatment is introduced into the dissolution tank, the pulverization or aggregation of activated carbon is prevented by the even grinding operation of the grinder with the auxiliary grinding rod in the hopper, and also the rotary valve By interlocking operation, smooth dissolution supply is always possible without agglomeration of activated carbon, and a certain amount of activated carbon can always be introduced into the screw feeder hopper by the reliable detection operation of the paddle type level switch, and the bridge phenomenon of activated carbon by vibrator It is prevented to have the advantage that can increase the operating efficiency according to the activated carbon input as much.

Although the present invention has been described with reference to the accompanying drawings, many modifications and changes may be made without departing from the scope of the following claims.
