Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to high viscosity fluid conveyance vehicles, and more particularly to non-sagging materials in the automobile industry, such as vinyl chloride plastisol body sealers, undercoat paints used in the underfloor skin of car bodies, and in the construction industry. This invention relates to a transport vehicle equipped with containers such as tanks suitable for transporting high-viscosity fluids such as organic paint materials for interior and exterior use.

In general, low-viscosity fluids are easy to discharge using gravity, natural flow, or forced transport at high speed using pumps.2, loading and unloading can be streamlined, and large-capacity containers, Large-capacity transportation means such as tanks and containers are becoming widespread.

However, as seen in the above-mentioned high-viscosity materials, high-viscosity fluids have relatively low viscosity when flowing or stirring due to the properties given in the product design.

In a static state, the viscosity recovers almost instantaneously.

Depending on the type of product used, the viscosity reaches tens of thousands to hundreds of thousands of centipoise, which is several times higher than the dynamic state, and shows almost no fluidity, which is the so-called non-sagging property.

Many have non-leveling properties,
Filling and conveying of highly viscous 1 degree materials with highly thixotropic properties, i.e. thixotropy.

Traditionally, lorries and 8-container systems were not suitable for discharging, and the waste was transported in small-capacity containers such as conventional drums, bales, and 5-gallon square cans.
At present, pumps such as dedicated air pumps are used to discharge, transfer, discharge, and apply, which can be streamlined by transporting large containers.

This is a great way to save labor.

To explain more specifically, even if it is injected into a large container or tank (lorry) using a pressure pump, or it is poured from a material manufacturing tank or storage tank by gravity flow or by a gear pump, etc., with stirring,
When discharging high viscosity materials that have recovered to static viscosity, even if the end of the tank or the bottom of the container or the end bottom is fully opened, the discharge speed will be unsatisfactory as long as it depends on gravity. Disadvantageously, a large amount of non-sagging material remains on the inner wall of the container;
Particularly in tank trucks, it is physically impossible to discharge these residual materials from the deep part of the container unless it is done manually by scraping them out, and there are also quality problems such as the entrapment of bubbles, which is completely impractical. has been considered a thing.

The present invention was developed in order to overcome the difficulties encountered when transporting the above-mentioned high-viscosity fluids using a lorry system. A piston plate whose surface is slidable is provided, and the piston plate can be pressed and moved by a double-acting hydraulic cylinder.

The inside of the container divided into two parts by the piston plate is a loading chamber for high viscosity fluid on the side in the suppression direction from the starting point of the piston plate, and the opposite side is a preliminary chamber, and the loading chamber is filled with high viscosity fluid from above. A high viscosity fluid conveying vehicle is provided with an inlet and an outlet so that the fluid can be introduced and discharged as the piston plate moves, while the terminal end of the loading chamber is open and the lid body is used to freely open and close the loading chamber. The purpose is to provide.

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a side view of a transport vehicle in which a high-viscosity fluid storage container l is placed on a loading platform, and FIG. 2 is a plan view of only the storage container l shown in FIG. 1.

The storage container 1 consists of a double tank, and is placed on the loading platform with a slight downward inclination toward the rear. Inside, a sliding piston plate 2 is disposed via gaskets 2a and 2b attached to the inner wall around the periphery, and a pair of parallel double-acting hydraulic cylinders 8.3 mounted on the front part of the container 1 is used to maintain balance. It is possible to reciprocate in the x and y directions of the arrows in response to the suppressed drive. On the other hand, the rear end of the container 1 is open, and the opening can be sealed or opened by rotating the rear lid 4, whose upper end is pivotally attached, up and down with an opening/closing cylinder 5.

The piston plate 2 is now shown in its starting position,
Inside the container, a loading chamber A for a high viscosity fluid is formed behind the piston plate 2 in the pressing direction (X direction), while a reserve chamber B is formed on the opposite side.

A pair of guide rails 6.6 extending in the directions of arrows X and Y are provided on both sides of the inner wall of the loading chamber A, and are designed to guide the piston plate 2 so that the reciprocating movement thereof is performed appropriately. . Further, an introduction lower is provided so that high viscosity fluid can be introduced from the upper part of the cargo compartment. The introduction lower also serves as an inspection window for monitoring the state 1 of high-viscosity fluid when it is discharged, for example, the balance between the level of the fluid and the discharge speed. It is located at the top. On the other hand, a discharge port 8 for discharging high viscosity fluid from the cargo compartment A is provided below a rear lid 4 which is pivotally connected to the end of the cargo compartment A so as to be openable and closable in the drawing. Of course, the outlet 8
is K instead of being provided on the rear cover.

It can also be provided near the end of the container. In addition, 9 is the rear lid 4
This is a locking device. ' On the other hand, the preliminary chamber B has a self-air supply and discharge port l at the top.
O is provided so that when the piston plate 2 is reciprocated, no negative pressure or pressurization that impedes its movement occurs, and
Opening lids 11, 11 are provided at the lower portions of both sides, so that the preliminary chamber B can be inspected or cleaned. Note that lla is a guide cover.

When transporting a high viscosity fluid, the introduction lower is opened in the state shown in Figure 2, and the high viscosity fluid is introduced from the introduction lower. Loading chamber A is filled with an appropriate amount (usually up to 70 to 80%) of high viscosity fluid, the introduction lower is closed, and the cargo is transported to a desired location.

Therefore, the discharge port 8 is connected to a storage tank, and the lever 12 is operated to operate the pair of double-acting hydraulic cylinders 3, 3 via the hydraulic switching valve 13, and the piston plate 2 is moved in the direction of the arrow X. Press and move. As a result, the dynamic viscosity of the high-viscosity fluid in the inner wall sliding portion decreases due to shear stress caused by the movement, and the fluid sequentially falls from the discharge port 8 into a storage tank (not shown).

Thereafter, it may be operated by the lower lever 12'.

Note that 14 is a scaffold. In addition, when the piston plate 2 moves, the gaskets 2a and 2b on its periphery slide on the inner wall of the storage container l, so that the high viscosity fluid adhering to the inner wall is scraped away.
100% will be completely discharged.

The piston plate 2 is preferably moved forward so that an excessive load is not applied to the inner wall of the tank, and so that the high viscosity fluid is given a shear rate higher than its yield value at the sliding portion of the wall surface. Such control can be adjusted using the lever 12 while being monitored through the inspection window of the introduction lower, or it can be automatically controlled by a conventional method using a separate predetermined detection device.

The cargo compartment A is opened by switching the hydraulic switching valve 13 with the lever 12'' and operating the opening/closing cylinder 5.
can be opened to an opening angle of approximately 65°.

Therefore, inspection and cleaning of the interior of the cargo compartment A is easy. On the other hand, the preliminary chamber A can be easily inspected and cleaned by opening the opening lid 11.

Note that although the drawing shows a transport vehicle on which one storage container is placed, a plurality of storage containers having the same function can also be placed thereon.

According to the carrier according to the present invention, even if the static viscosity is several hundred thousand centipoise, the thixotropic index (viscosity at 2 rpm measured using a B-type viscometer/viscosity at 20 rpm) It is possible to sufficiently extrude and discharge high viscosity fluid with a ratio of several times or more. Therefore, it becomes possible to transport a large amount of high viscosity fluid. Further, air is not mixed in when discharging from the container as in the conventional case, which is advantageous from a quality standpoint.
