Abstract

PURPOSE:To prevent a bad smell and to make it possible to efficiently perform drying, by forming a wavy uneven surface of piled-up excretion. CONSTITUTION:The floor 2 of a charging part has a gradient in the direction opposite to the advance direction of excretion and the peripheral partition wall thereof is provided with a large number of slits 5 so as to be capable of transmitting only separated moisture. In the range provided with the slits 5, a transmitted water recovery groove 6 coming to a supernatant solution flow passage is provided and constitutes a part of the flow passage provided so as to be guided to a purification tank 8 through a manhole 7. Lime treated excretion containing a large amount of moisture is thrown in the deepest part of a pile-up drying part. Only moisture is flowed into the recovery groove 6 from the slit of the partition wall 3 and guided to the purification tank 8 through the manhole. The piled-up excretion on the floor 2 is gradually dried by a fan.

Description

DETAILED DESCRIPTION OF THE INVENTION Object of the Invention (Apart from Industrial Use) This invention relates to a method and apparatus for drying livestock manure.

(Prior Art) Livestock barns, especially pigpens, produce excreta such as calamus urine from large salmon, and the treatment of this waste, along with the prevention of odor, has become a major problem in livestock farming.

In order to use it as fertilizer, it is necessary to make it harmless, dry it, and make it into a form that is convenient for transport.

For this reason, many drying methods such as fermentation drying and fire drying are
I'm being lied to. In recent years, lime treatment by mixing quicklime has become popular due to its ease of treatment, and it is expected that this method will be used to add water to treated manure and to efficiently dry it.

(Problem to be Solved by the Invention) For efficient drying, it is necessary to bring the treated excrement into contact with air as low in humidity as possible over as wide an area as possible, and this must be done as efficiently as possible. It is necessary to dry the product in a drying device with a small area.

In addition, the apple drying equipment is suitable for continuous operation, and the operation is preferably automated.

Furthermore, it is said that lime-treated excrement makes it easier to separate water, but it is desirable that this separated water is also evaporated.

The present invention aims to provide a method and device for treating excrement that satisfies all of the above requirements.

1111 features of the invention (Means and effects for solving the problems) In this invention, in order to achieve a greenhouse effect, the treated excrement is first dried in the direction of movement of the excrement in a drying device constructed as a house with transparent walls. It is carried onto a floor surface that slopes in the opposite direction. This first removes the moisture seeping out from the wing.

Next, a stirring and conveying machine that moves while rotating,
Il while being stirred! It is transported towards the next exit, and this...
Then, the heated, low-humidity air near the ceiling of the house is blown by a fan and gradually dries.

This stirring conveyor reciprocates from the loading section to the exit and vice versa, but if the conveying action is performed intermittently during this time, the portions that have been subjected to the conveying action will be removed from the portions that were not. The surface of the feces forms a wavy, uneven surface. By forming this uneven surface, the contact surface between the true surface and the drying air flow is expanded, and drying can be promoted.

On the other hand, the water separated in the gradient bed is collected, subjected to purification treatment, and then evaporated into the atmosphere by means of an air tank or another V) transpiration system.

However, if there is extra drying capacity in the house, the feces may be evaporated in the house for drying. It's okay.

(Practice) Fig. 1 is a 1000-sided view of the drying device V)I of the present invention in the practical direction, Fig. 2 shows its AA cross section, and Fig. 3 shows its B-BWr cross section.

Drying device Fi Sunlight *'t for glass, vinyl, etc. Transparent wall f + v Concrete floor installed in house 1 2,
The urine Q is processed by the partition wall 3 formed in a U-shape on top of it.
Form a compost drying section.

The open part of the U-shaped partition wall is a dry matter removal part, and the processed excrement 4 is carried into the inner part thereof.

The floor 2 of this input section has a slope in the opposite direction to the advancing direction of the blades, as shown in a partially enlarged cross section in Fig. 4, and there are many partition walls 3 around it so that only the separated moisture can pass through. A slit 5 is provided. Then, in the area where the slit 5 is provided on the outside of the lIM wall 3, a permeation water collection $6 is provided, which serves as a urinary tract for the supernatant liquid that permeates through the slit 5, and the water is collected via the manhole 7 to the purification 1a8. This will be part of the outline provided to help you.

The agitation conveyance machine, in which the agitation conveyance machine 9 is installed across the dry deposition depth, has agitation blades 10 radially over its entire length, and is rotated by a motor (not shown), and rotates on the rail portion 11 on the outside of the partition wall 3. Round trip luck along bulkhead 3! kl
It is installed on I5T females.

My father has installed a fan 12 on the ceiling of House 1.

The lime-treated color Q that retains the moisture of the manure is collected in the compost drying section V)
However, since the water is easily separated by the lime treatment, only the water flows into the recovery fl#6 through the slit in the space e3, passes through the manhole, and is drained into the purification tank 8. After being purified, it is released into the river. On the other hand, the excrement remaining on the floor 2 is gradually dried by evaporating moisture by blowing warm, low-humidity dry air near the ceiling of the house with a fan.

As shown in FIG. 5, the agitation conveyor 9 rotates counterclockwise to convey and agitate the excrement in the advancing direction using the blades 10, thereby drying it by exposing the undried portion to the surface. promote

Historically, as shown in Fig. 5, while moving the agitating conveyor 9 in the direction of the double arrow, the blades 10 are driven to rotate at di1 minute, and during the 6th section, the blades 10 are rotated without being driven at the f section. let In this way, the 6 parts of the feces will be collected in the f part,
As a whole, the deposits have a wavy and uneven surface.

Such a shape has a larger surface area than a pile with a dry surface (for example, if the cross section of this wave is an equilateral triangle, the surface area will be 2@ compared to a dry case), which promotes drying accordingly. You can.

For the switching of the Od section and the F section, a control method using a timer of the drive motor or control based on position IT detection as the vehicle advances is used.

FIG. 6 is a partial sectional view of another embodiment in which Q# permeable water is dispersed from the slit 5 of the partition wall 3 within the same house. S water permeates through collection groove 6 or manhole 7!
! It will be collected on 13th.

This permeated water is supplied to the fog generator 15 by the submersible pump 114, and is dispersed into the house as @1 fog. This tighter installation has the problem of increasing humidity in the house and slowing down the drying of the bulk, but
There is no need to separately create 8 installations, and there is an advantage that the installation is simple. By intermittent driving of the agitation conveyor υ, the surface area is expanded and the contact surface with the drying air stream is increased, which speeds up the drying process, but at the same time, the natural moisture is separated as permeation water at the initial stage when it is introduced into the greenhouse. This reduces the rate of water expulsion of the wings and speeds up drying. Therefore, there is a remarkable effect of making the drying device small and highly efficient.
