[0002]

2. Description of the Related Art Organic waste such as kitchen garbage causes off-flavors and dripping due to decay, which significantly impairs the hygiene of living spaces and working spaces. JP-A-03-89954, JP-A-Heisei 0-89
JP-A-4-305284 and JP-A-10-180236
The garbage disposal system using the disposer disclosed in Japanese Unexamined Patent Publication (KOKAI) can improve the hygiene of the work space of kitchens and offices because it can treat organic waste from the place where it is generated in home kitchens and offices every time it is generated. Is an extremely effective system.

[0003]

However, in order to use these systems effectively, it is necessary to design piping so that the garbage processed by a disposer or the like as garbage crushing means can be completely drained. No effective design guideline and piping flow means have been proposed. In particular, in a multi-family house or the like, in order to reduce building energy for building and consumption materials, the consolidation is progressing, and the size of the congregation tends to be large and high-rise. The consolidation of houses has a problem in that the number of kitchen crushers such as disposers connected to the same pipe is increased, and the risk of pipe blockage is increased.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems. The present invention has been made to solve the above-mentioned problems. The purpose is to provide.

[0005]

Means for Solving the Problems In order to solve the above problems,
In the garbage disposal system according to the present invention, the transfer medium is supplied directly to the pipe section for transferring the crushed garbage and / or via the garbage crushing means section to prevent the accumulation of the crushed garbage in the pipe. Water, medium water, rainwater, etc. can be used as the transfer medium to be supplied. To save water, use a gas-liquid two-phase flow in which gas is mixed with water in the supply fluid, or alternately flow water and gas. Is also effective. Furthermore, since the fluidity in the piping of the crushed garbage is significantly reduced due to the contamination of the piping by the oil-containing drainage discharged from the kitchen for business use and the kitchen sink of the house, the heating and supply of water, which also serves as the cleaning of the contamination in the piping, Addition of a chemical containing a cleaning chemical such as an alkali or an enzyme is also effective.

[0006] The supply condition of the transfer medium is different depending on the installation condition of the pulverizing equipment such as the disposer which is the garbage transfer means. In a multi-family house, the length of the pipe connected to the crushing equipment, the gradient, and other conditions differ depending on the story and the dwelling unit plan. If there is only one kind of transfer medium supply condition (supply program) to the pulverizing equipment, dwelling units with the risk of pipe blockage due to insufficient supply of medium, and dwelling units with excessive supply of transfer medium and energy consumption are born. I will. Therefore, in order to avoid these problems, garbage information such as the amount of garbage put into the garbage crushing means and the garbage composition, and the pipe diameter, gradient, pipe length, joint shape, etc. In accordance with the design information, a garbage processing system in which a control unit capable of controlling the transfer medium supply condition is added to the transfer medium supply unit is installed, and the transfer medium supply unit is finely controlled in accordance with the individual conditions of the kitchen crushing unit, Achieve optimal transfer media supply. In addition, the relationship between the required minimum supply amount of the transfer medium when the crushed garbage is transferred by a pipe, the garbage information such as the amount of the crushed garbage, and the pipe design conditions such as the pipe length was found. These are the first, second and fifth inventions of the present application.

[0007] Wastewater from cooking work and the like also flows into the pipe to which the garbage crushing means is connected. For this reason, there may be a case where solid matter depending on drainage other than cooking work remains in the pipe. In addition, when the garbage crushing means is installed at a high position, the pipes are composed of three types of pipes: horizontal branch pipe-vertical pipe-horizontal pipe, but in the vertical pipe section, drainage flows along the pipe wall, Since the solids fall, the solids reach the horizontal pipe first and hinder the fluidity in the pipe. For the washing of these solids, a transfer medium pre-supply unit for starting the supply of the transfer medium was provided before starting the crushing operation by the garbage crushing means, thereby ensuring the transferability of the crushed garbage in the pipe. This is the third invention of the present application.

Further, in the transfer of the garbage to the pipes in the horizontal branch pipe and the horizontal pipe portion, after the step of crushing, mixing with the transfer medium and flowing, the crushing of garbage crushing means for flushing the mixture from behind is performed. It is necessary to supply the transfer medium after the operation is completed, and the supply conditions can be optimized according to the garbage information such as the amount of garbage input into the garbage crushing unit and the garbage composition and the design information of the piping connected to the garbage crushing unit. It was taken. This is the fourth invention of the present application.

By providing an automatic water supply mechanism comprising a water supply valve capable of controlling the opening and closing of the supply of the transfer medium and its control means, the pipe transferability of the crushed garbage can be secured with a simple structure.
The variable amount of water is also controlled as an average amount of water supply by controlling the intermittent opening and closing intervals of the water supply valve and performing intermittent water supply. In intermittent water supply, the flow in the pipes microscopically undulates and can generate a larger transfer energy than in the average flow. This is the sixth and seventh inventions of the present application.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Organic waste such as kitchen garbage is crushed by kitchen garbage crushing means such as a disposer, and is transferred by pipes with water. At the factory, the waste is transferred to the waste disposal unit installed at the factory, and purified at the waste disposal facility. Alternatively, the sewage treatment plant collectively purifies wastewater together with domestic wastewater. Organic waste is treated at the place where it is generated, and at home by kitchen crushing means such as a disposer installed in the kitchen, so that it can be disposed of whenever waste is generated, and organic waste such as kitchen trash within the house. It is no longer necessary to store the garbage until the day of garbage collection by the government, etc., and the hygiene of the living space and working space is improved. In addition, when storing garbage in a house, etc., organic waste can be separated in advance, so not only storage of other dry waste becomes sanitary, but also storage place It is no longer necessary to have a closed structure,
Storage becomes easy. In addition, in the process of collecting dried waste other than organic waste into garbage, collecting it, separating it with a machine, etc., and recycling it, this system that provides preliminary separation of organic waste Greatly improves workability.

In order to bring out the environmental effect of the disposer system, it is necessary to surely transfer the garbage crushed by the garbage crushing means such as a disposer to a subsequent step. SUMMARY OF THE INVENTION The present invention provides a pipe transfer system which is a key for putting a disposer system into practical use and which can reliably transport crushed garbage.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In order to make it easier to understand the contents of the present invention, embodiments of the present invention will be described below with reference to the drawings.

First, the flow state of the garbage crushed by the disposer in the pipe was analyzed. FIG. 1 shows a schematic diagram of the flow of the crushed garbage in the pipe when the garbage is crushed and water is supplied for 20 seconds after the crushing is completed. In the figure, part A is a slurry part in which crushed garbage and transfer water are mixed at the time of crushing of garbage, and part B corresponds to post-water supply after crushing is completed. When the supply time of the portion B is short, the energy for pushing the slurry from behind is small, and the slurry does not flow. Also, if the amount of water supplied at the time of crushing is smaller than the amount of crushed garbage, the viscosity of the slurry increases,
It was found that the fluidity was significantly reduced.

In the vertical pipe section, the drainage in the slurry flows along the pipe wall, and the solids fall, so that solid-liquid separation occurs. Solid-liquid separation becomes more pronounced as the length of the vertical pipe increases, and becomes even more severe when a special joint is used for the pipe. It was also clarified that since the falling solid portion had no moisture between the solids, it could not be washed away if the kinetic energy of the water arriving late was small.

The water supply program was determined based on the analysis of the flow state of the crushed garbage in the pipe. FIG. 2 and FIG. In FIG. 2, a pre-flow time for avoiding washing of solids remaining in the pipe and / or solid-liquid separation in the vertical pipe is secured in the pre-water supply section prior to the disposer operation. The time and flow rate of the pre-water supply section are variably controlled in accordance with the length of the vertical pipe, the piping conditions of the connection joint, and the amount of crushed garbage. The water supply section synchronized with the kitchen crushing section was to supply a large amount of water at the beginning to keep the slurry concentration sufficiently low, and to increase the water supply amount again in the second half to prevent the trap inside the trap connected to the latter stage of the disposer. . For the post-water supply, water for washing the horizontal branch pipes and others by intermittent water supply and water for flushing the slurry from the rear were appropriately supplied. In this program water supply, the flow rate and water supply time in each step can be arbitrarily set according to the information on the amount of garbage introduced into the disposer and the information on the piping connected to the disposer.

FIG. 3 shows a program in which the number of steps is reduced and the mechanism is simplified. The operation of the disposer was continued after the garbage was crushed, and the stop of the disposer and the stop of water supply were synchronized. In that case, the amount of water required for the post-water supply is also supplied during the disposer operation. In addition, sponge bo
Flow of particles and solids such as beads, such as plastic beads, can be used not only to clean the crushed garbage that has accumulated inside the pipes, but also to recover the contamination of the inner wall of the pipes caused by long-term use of the pipes. It is effective.

Table 1 shows the relationship between the total amount of water supply and the pipe fluidity. In this water supply, the water supply program in FIG. 3 is further simplified, and water supply is performed in one step in synchronization with the operation of the disposer. The Q / (LH × W) value is shown in the table as an index of the water supply amount together with the pipe fluidity. Q / (LH × W)
Is 1.5 or more, preferably 2.0 or more.
