Description

[Detailed explanation of the invention] This invention turns high viscosity heavy oil used as fuel for diesel engines and boilers into homogeneous fuel oil by atomizing and dispersing the sludge contained therein. This generally relates to a homogenizer that crushes and disperses coarse particles in a fluid containing coarse particles to transform it into a homogeneous fluid.

Although sludge that exists as coarse particles in heavy oil is combustible, it cannot be easily atomized and combusted using a fuel injection nozzle installed in a typical diesel engine.

Therefore, when using heavy oil as fuel oil, conventionally, the sludge contained in the heavy oil has been removed using a centrifuge or the like.

However, in order to dispose of the removed sludge, it is mainly incinerated, and there is a problem in that a large amount of money is required for the equipment for this process and the tanks for temporary storage and firing.

Recently, in order to solve this problem, sludge that exists as coarse particles has been crushed to become fine particles and dispersed.
A device (fuel oil homogenizer) has been developed that converts heavy oil containing sludge into homogeneous heavy oil without removing the sludge using a centrifuge or the like.

As an example of this device, the buttons shown in FIG. 1 and FIG. 2 are known.

This device rotates a plurality of rolls 2 arranged radially from the axial center of the tire 1 inside a cylindrical tire 1 in the direction indicated by an arrow 42, and preheats the inside of the tire 1. The poor quality heavy oil 3 is sent to the inner circumferential surface of the tire 1 and falls in the form of a thin oil film along the inner circumferential surface of the tire 1.
a and the outer circumferential surface 2a of the roll 2, crushing coarse particles in the poor quality heavy oil into fine particles, and compressing the tire 1.
The heavy oil that has been homogenized by being dispersed and mixed inward is taken out from a discharge port located at the bottom of the device.

However, in such a device, the only surface to be treated for atomizing coarse particles such as sludge is the inner circumferential surface 1a of the tire 1, and moreover, the heavy oil flowing along the inner circumferential surface must be made into a thin film. Therefore, there was a problem in that the processing capacity was small compared to the size of the device.

Further, since the amount of heat generated by the compression operation between the inner circumferential surface 1a of the tire 1 and the outer circumferential surface 2a of the roll 2 is small, it is only possible to raise the temperature of the heavy oil by the homogenization process using this device.

Therefore, in order to send the heavy oil processed by this device to a diesel engine or boiler, it was necessary to provide an additional heating device.

This idea was made in consideration of the above circumstances, and includes a plurality of rotating crushing plates fixed at appropriate intervals to a rotating shaft passing through the casing and rotating together with the rotating shaft, and a gap between each rotating crushing plate. By sliding relative to a plurality of fixed crushing plates which are arranged in a sandwich and whose outer periphery is fixed to the casing, the heavy oil sent from the oil feed hole penetrating the rotating shaft to the gap between the rotating crushing plates is homogenized. By increasing the temperature and increasing the processing capacity, it is possible to supply homogenized heavy oil to diesel engines and boilers without heating it, or to crush coarse particles in fluids that generally contain coarse particles. The object of the present invention is to provide a homogenizer capable of dispersing and homogenizing the fluid.

A discharge port 20 is formed in the lower part of the outer case 10a.

The discharge port 20 stores homogenized fluid through a filter 21 and communicates with a service tank 22 .

The fluid such as heavy oil sent into the service tank 22 is sent to the engine 24 etc. via the filter 23.

The inner case 10b includes a cylindrical portion 26 that surrounds the outer periphery of the rotating shaft 11 and has one end (the right end in FIG. 3) fixed to the outer case 10a via a fastener 25 such as a bolt, and this cylindrical portion. The rotating shaft 1 is connected to the rotating shaft 1 through a seal member 27 such as an oil seal, which is formed integrally with the cylindrical portion 26 on the other end side of the 26.
1 and a sealing wall portion 28 through which the tube 1 is inserted in a watertight manner.

The fixed crushing plate 13 is fixed to the inner case 10b by one or more notch grooves provided on the outer circumferential edge of the fixed crushing plate 13 and by grooves formed on the inner circumferential surface of the cylindrical portion 26 in the axial direction of the rotating shaft 11. The fixed crushing plate 13 is made movable only in the axial direction by fitting with one or more protrusions 29 formed along the button.

The circumferential wall of the cylindrical portion 26 includes the inside of the cylindrical portion 26 and the peripheral wall of the cylindrical portion 26.
A passage hole 30 that communicates with the outside (the space surrounded by the outer surface of the cylindrical portion 26 and the inner surface of the outer case 10a) is formed facing the gap between the fixed crushing plates 13 adjacent to each other.

The rotary crushing plate 12 is fixed to the rotary shaft 11 by one or more notch grooves provided on the inner circumferential edge of the rotary crushing plate 12 and along the axial direction of the rotary shaft 11 on the outer circumference of the rotary shaft 11. The rotary crushing plate 12 is made movable only in the axial direction by fitting with one or more formed protrusions 31.

The oil supply hole 14 is arranged on the outer periphery of the rotating shaft 11 facing the gap between the inlet 14a arranged at the shaft end of the rotating shaft 11 protruding to the outside of the casing 10 and the rotating crushing plates 12 adjacent to each other. It communicates with a plurality of outflow ports 14b.

The rotation of the rotating shaft 11 is BOOM! This is done by an electric motor 35 or the like via J32, 33A, a belt 34, or the like.

is connected.

In the jacketed oil pipe 40, a pipe for flowing steam is placed along the outside of the pipe for sending heavy oil, and the heavy oil is heated by the steam, so that the heavy oil is cooled in the middle of the pipe and the flow is not obstructed.

The operation of this device will be explained below.

The heavy oil containing coarse particles in the settling tank 37 is sent to the oil feed hole 14 of the rotating shaft 11 through a jacketed oil feed pipe 40.

Then, the heavy oil sent to the oil feed hole 14 flows through each outlet 1 opened in the gap between the respective rotary crushing plates 12.
4b to the gap between the two crushing plates 12 and 13, and the coarse particles are crushed and dispersed by the relative sliding of the two crushing plates 12 and 13, becoming homogenized, and raised by the frictional heat of both the crushing plates 12 and 13. The passage hole 30 of the inner case 10b is heated.
The water passes through the exhaust port 20, filter 21, service tank 22, and is sent to the engine 24, etc.

When passing through the filter 21, the uncrushed coarse particles captured by the filter 21 are returned to the IJ song gun 37 through the return pipe 41, and sent into the device again to be circulated and crushed.

Even if the heavy oil sent to the oil feed hole 14 contains water, the water is crushed and dispersed by the relative sliding of the two crushing plates 12 and 13 together with the coarse sludge particles, forming a homogeneous emulsion. and converted into combustible heavy oil.

In addition, the amount of heat transferred to the heavy oil during processing due to the frictional heat of both friction plates 12.13 is determined by the flow rate of heavy oil, the both crushing plates 12.1
It can be adjusted by changing the size of the gap between the three.

Further, in the above-mentioned embodiment, the fixed crushing plate 13 is supported by the inner case 10b formed in a cylindrical shape. The fixed crushing plate 13 may be supported by a plurality of rods that extend and surround the outer periphery of the rotating shaft 11.
Any type of material may be used as long as it forms a space communicating with the discharge port 20 between the outer periphery of the outer case 3 and the inner surface of the outer case 10a.

As explained above, in this invention, a plurality of rotary crushing plates are fixed at appropriate intervals to a rotating shaft passing through the casing and rotate together with the rotating shaft, and a plurality of rotating crushing plates are inserted in the gaps between the respective rotating crushing plates. Heavy oil is sent from the oil feed hole penetrating the rotating shaft to each gap between the rotating continuous breaking plates by relative sliding with a plurality of fixed breaking plates arranged in parallel and having their outer peripheries fixed to the casing. Since it homogenizes heavy oil by crushing and dispersing coarse particles, continuous processing is possible, and by increasing the number of both crushing plates, the processing surface for homogenizing heavy oil can be easily processed. It is possible to increase the processing capacity without significantly changing the size of the device itself.

Furthermore, since the temperature of the heavy oil being processed can be raised by the frictional heat between the two crushing plates, a separate heating device is provided as in the past when supplying the homogenized heavy oil to the combustion chamber of an engine, etc. Excellent effects such as eliminating the need for this will occur.
