A dewatering cake distribution stacking device.

In general, the sludge generated while treating wastewater including sewage is dehydrated more than 80% of the water content using mechanical or physical methods, and is supplied as raw materials for construction materials such as cement or landfilled.

In order to reclaim the sludge as a raw material of the building material or to be reclaimed, the dewatered sludge is transported through an arm roll box or the like.

Manual / automatic loading is used to transfer the dehydrated cake to the place of use, and the automatic method loads the dehydrated cake into the arm roll box using a transfer member.

However, in the conventional dewatering cake distribution stacking device, the dewatering cake is not uniformly loaded on all parts of the arm roll box, and after the predetermined amount of dewatering cake is loaded, the operator enters the arm roll box and flattens using the equipment.

That is, the conventional dewatering cake distribution stacking device simply discharges the dewatering cake to the arm roll box and loads the dewatering cake so that the flattening of the dewatering cake must be performed. Accordingly, the labor cost increases and the manpower is not efficiently utilized. In addition, since the work takes time due to the flattening, there is a problem in that the loading time of the dehydrated cake is long and the loading amount of the dehydrated cake per unit time is small.

On the other hand, the flattening of the dehydrated cake is cumbersome and inconvenient, and in some cases, the transport vehicle is discharged immediately after loading the dehydrated cake without the flattening process of the dehydrated cake. In this case, the dehydrated cake loaded in the arm roll box overflows to the road. There is a problem of polluting roads and the like.

The present invention is to solve the problems as described above, when the dewatering cake generated in the water treatment plant, sewage treatment plant, etc. to be loaded in the arm roll box for recycling or landfill, etc. The objective is to provide a dewatering cake distribution stacker that saves time and uses manpower efficiently.

Dehydration cake distribution stacking apparatus according to the present invention for achieving the object as described above, the frame is constructed so that the dehydration cake using transport arm roll box at the bottom; A dewatered cake conveying tube mounted in the frame as a hollow inner tube and having a plurality of outlets formed at predetermined intervals along an inlet and a longitudinal direction into which the dehydrated cake is introduced; A transfer member mounted inside the dewatered cake transfer pipe and transferring a dewatered cake introduced into the dewatered cake transfer pipe; And a valve for opening and closing the outlet of the dewatering cake transport pipe, wherein the valve is selectively opened to discharge a uniform amount of the dewatering cake through a plurality of outlets of the dewatering cake transport pipe to release the dewatering cake inside the arm roll box. It is characterized in that the loading so as to flatten.

According to the dewatering cake distribution stacking device according to the present invention, the dewatering cake conveying pipe for loading the dewatering cake into the arm roll box is automatically and manually opened and closed according to the loading amount of the dewatering cake so that the dewatering cake is simply loaded in the arm roll box. Rather, the dewatering cake is loaded on all parts of the arm roll box in a uniform amount so that the operator does not perform a flattening operation so that the dewatering cake does not overflow in the arm roll box, thus reducing labor costs and increasing work efficiency and reducing loading time. This can increase the load per unit time.

-Manual method.

The operator opens only one outlet, for example, the first outlet 22-1, and closes the remaining outlets 22-2, 22-3, and 22-4 of the plurality of outlets.

Therefore, the dewatering cake S inside the dewatering cake transport pipe 20 is discharged only through the first outlet 22-1 and loaded in the box 1.

When the operator visually checks the inside of the box 1 and the appropriate amount of dewatering cake S is loaded below the first outlet 22-1, the worker first passes through the first outlet 40-1. -1) is closed and only the second outlet 22-2 is opened through the second valve 50-2 so that the dewatering cake S is discharged only through the second outlet 22-2.

In this way, the operator can load the dewatering cake S in the box 1 without any additional flat work by opening and closing the outlet while visually checking the amount of the dewatering cake S loaded in the box 1.

In the manual method, when the sensor and the alarm is applied, the operator can open and close the outlet through the alarm without checking the loading amount of the dehydration cake (S).

-Automatic method.

The first to fourth sensors 50-1, 50-2, 50-3, and 50-4 respectively detect the loading amount of the dewatered cake S. At this time, all of the first to fourth outlets 22-1, 22-2, 22-3, and 22-4 may be opened or only closest to the inlet 21.

The controller compares the load values detected by the first to fourth sensors 50-1, 50-2, 50-3, and 50-4 with the preset reference values and if the current load value is greater than or equal to the reference value, Control opening and closing of the valve to close.

(S40) Loading finished.

The first to fourth load cells L1, L2, L3, and L4 respectively detect the weight of the box 1 and transmit a detection value to the controller, and the controllers transmit the first to fourth load cells L1, L2, L3, The average of the values detected in L4) is calculated, and the loading is terminated if this calculated value is equal to the previously stored load. The end of the stacking is performed by closing the first to fourth discharge ports 22-1, 22-2, 22-3, and 22-4 and stopping the transfer member 30.

Until now, a number of outlets were opened and closed by respective valves to explain the uniform loading of dewatering cakes into the box. It is also possible to uniformly load the dehydrated cake by adjusting. This is because the larger cross-sectional area is because the resistance of the dehydrated cake is different because the resistance is smaller than that of the small cross-sectional area.

As described above, by controlling the opening and closing of the outlet, the dewatering cake can be flatly loaded without a separate flat work, and a flat scraper 70 (FIGS. 8A and 8B) can be applied to increase the flatness. .

As shown in FIGS. 8A and 8B, the scraper 70 has a flat plate shape and is lifted to the frame 10 so that the scraper 70 does not interfere when the box 1 is moved and is disposed inside the box 1 when the dewatering cake S is flat. It is installed to be able to move up and down, and is installed to enable linear reciprocating movement inside the box 1 through a straight line means.

The lifting means may be a hydraulic cylinder (71) or the like.

The linear means may be, for example, a pair of rails 72 mounted on the frame 10, a carrier 73 moving along the rails 72, and a motor driving the carriers 73 in both directions.

The elevating means is provided in the carrier 73 of the linear means.

Lifting and linear reciprocating movement of the lifting means and the linear means is controlled by a sensor.

That is, when the box 1 is mounted under the dewatering cake transport pipe 20, the scraper 70 is raised without interference, and when the loading of the dewatering cake S is completed, the box 1 is fixed to a predetermined height by automatic / manual. Descend. Subsequently, the dewatering cake S is flattened by linear reciprocation (one or more times) inside the box 1.

When the flattening of the dewatering cake is completed, the box 1 is raised to the initial position again to withdraw the box 1.
