な手段を実施している。When crude oil or heavy oil is stored in a crude oil tank or heavy oil tank for a long period of time, sludge builds up on the bottom of the tank.In order to reduce the buildup of sludge, large tanks are equipped with a side-filling mixer on the side wall. ~
However, in the case of large tanks, sludge deposition is still unavoidable, so the following measures are taken.

るのであるが人件費が嵩む等の問題がある。That is, in the hot water dissolution method, hot water is first created by steam heating, and the sludge is dissolved by pumping it into a tank and circulating it, but this not only increases costs but also takes time to dissolve. Next, in the light oil dissolving method, light oil is poured into a tank and the sludge is dissolved, but similarly it takes time to dissolve it.Furthermore, in the sludge scraping method, after the tank is emptied, a worker must enter the tank. The sludge is then manually removed from the tank, but there are problems such as increased labor costs.

ポンプとを具えたことを特徴とする。The present invention was proposed in view of the above circumstances, and aims to provide a sedimentary sludge dispersion device that reduces the cost of tank cleaning and also shortens the construction period. a self-propelled frame car that travels on the bottom surface of the tank by remote control; a stirring means attached to the self-propelled frame car that stirs the sludge deposited on the tank bottom surface;
The present invention is characterized by comprising a pump attached to the self-propelled frame car that sucks together the sludge stirred by the stirring means with the stored liquid and discharges it upward.

, 7, 7, and 8 are left and right proximity sensors provided vertically protruding from the front and rear ends of the self-propelled frame car l, respectively, and 8 is a hydraulic motor provided on the self-propelled frame car l that expands downward. A vertical force having a conical part whose diameter at the lowest part is approximately equal to the outer diameter of the rotating brush described later, and which is rotated by a brush hydraulic motor lO to stir the sludge deposited at the bottom of the tank. A brush 11 is an axial flow pump that is installed in the cylindrical portion of the casing 8 and sucks in the sludge stirred by the rotating brush 9 and discharges it upward; 12 is a pump hydraulic motor that drives the axial flow pump 11; 13 14 is a cloth discharge pipe of appropriate length that is fitted into the upper end of the casing 8 and extends upward, and 14 is a hydraulic motor 4 for traveling provided on the self-propelled frame car l.
.. Hydraulic motor for brushes 10. Pressure oil to the pump hydraulic motor 12 and operating pressure oil are supplied to the self-propelled frame vehicle 1 via a hose 15.
Rotary join) 1
Due to the turning action of the hydraulic motor 4, the hose 15 supplies the pressure i to each of the hydraulic motors 4, 10, 42, etc. without being twisted despite the complicated running of the self-propelled frame car l.

Because the running frame l receives a downward thrust due to the reaction of the discharge flow caused by If the vehicle travels without slipping, the desired direction change can be performed by controlling the pressure oil to the left and right travel hydraulic motors 4.

The discharged sludge is dispersed into the stored crude oil.

定の張力で巻取ることが必要である。The cloth discharge pipe 13 is useful for raising the sludge to a desired height and dispersing it from a high position into the tank in cases where the sludge has a high specific gravity and will soon settle even after being diffused. When the vehicle 1 approaches the side wall of the tank while moving slowly along the bottom of the tank, the proximity sensor 7 touches the side wall, and as a result, the hydraulic motor 4 for traveling is reversed by the action of a control device (not shown), and the self-propelled frame is rotated. Car 1 automatically moves backward. The guard frame 3 protects the self-propelled frame car 1 when the self-propelled frame car 1 collides with the side wall of the tank. To prevent this, rotary joint 1
In both cases, it is necessary to wind up the hose 15 with a constant tension using a tension device (not shown).

It is possible to spread the deposited sludge into the crude oil by running it over the entire bottom surface.
