JPH0751206B2 - High viscosity fluid supply device - Google Patents

Description

Description: [Industrial field of application] The present invention relates to an improvement of a supply device for a stock solution of a horizontal vacuum filter used for concentrating and dewatering sludge and the like, and in particular, the present invention relates to a badge type device, This is to propose a device that exhibits excellent effects when used to supply a highly viscous fluid.

[Conventional technology]

Conventionally, as a device for supplying a highly viscous fluid such as sludge to a dehydrator, there is, for example, Japanese Utility Model Publication No. 62-35878. This is a belt press as a dehydrator, but in order to supply sludge evenly over a wide cloth, spread it in the width direction as much as possible with a diffuser and then feed it using a guide plate. There is.

[Problems to be solved by the invention]

In the case of JP-B-62-35878 mentioned above, since it is a belt press and the cloth is running, it is sufficient to diffuse the fluid to be supplied in a unitary direction in the width direction. In such a system, the supplied mud deposits on the supply unit. Therefore, averaging this requires special averaging equipment.

[Means for Solving Problems] The present invention solves the above-mentioned conventional problems, and its gist is to provide a mud-like material on the upper part of an endlessly stretched cloth. In an intermittent horizontal vacuum filter in which a box for receiving is provided and a diffuser for supplying mud is provided on the box, a diffuser impeller and a scraping impeller are internally provided in the diffuser and provided in the diffuser. The pinion sprocket is meshed with a chain rack stretched between the front and rear of the box, and is reciprocally mounted on a rail provided along the box.

[Action]

In the device according to the present invention, the muddy material diffused in the diffuser falls along the chute into the receiving box,
At this time, the mud can be uniformly supplied into the receiving box by moving the diffuser from one side to the other side on the receiving box. The present invention will be described below with reference to the drawings.

〔Example〕

In the figure, reference numeral 1 is a cloth, 2 is a vacuum suction box provided on the lower surface of the cloth, 3 is a receiving box for the mud-like object provided on the cloth above the vacuum suction box 2, and 4 is a side of the receiving box 3. It is a diffuser for supplying mud on the cloth, and is reciprocally provided along the receiving box 3 in the tension direction of the cloth 1.

The structure of the diffuser 4 will be described in detail in FIG. 2. Reference numeral 5 is a diffusion impeller, 6 is a scraping impeller, 7 is a motor for driving these, 8 is a drive chain, 9 is a partition plate,
Reference numeral 10 is a mud matter supply port, and 11 is a chute for supplying the mud matter. The diffuser 4 configured in this way has the rolling wheels 12 provided on the left and right side portions thereof so as to reciprocate on the rails 13 along the receiving box 3. Reference numeral 14 is a pinion sprocket driven by a motor 15, and 16 is a chain rack with which the pinion sprocket meshes.

With the mud-like material supply device configured as described above, when the mud-like material is supplied to the diffuser 4 (shown by the arrow (a)), the diffuser 4 is reciprocated along the receiving box 3. The muddy material supplied to the diffuser 4 uniformly drops from the chute 11 onto the cloth 1 in the receiving box 3 and the liquid can be sucked and separated by the vacuum suction box 2 below the cloth 1. .

That is, even if the mud-like material supplied to the diffuser 4 is a highly viscous material, first, the diffusion impeller 5 (using a spiral blade or the like) mechanically diffuses left and right (front-back direction of the drawing). Then, it is sent to the upper side, where it is scraped out by the scraping impeller 6 onto the chute 11 and falls, and the mud matter that has fallen is uniformly diffused left and right by the diffusion impeller 5. Therefore, the cloth is supplied uniformly over the entire cloth. At the same time, the diffuser 4 reciprocates along the receiving box 3, so that the mud can be uniformly supplied (uniform thickness) into the receiving box.

As described above, after the liquid content of the muddy material supplied into the receiving box is separated by the operation of the vacuum suction box 2, the receiving box portion is lifted by the hydraulic device, though not shown. By running the cloth 3, the cake S is taken out of the machine. (See FIG. 1) In this way, after the cake is separated, the washed cloth 1 is located in the receiving box, and the receiving box 3 is lowered to perform the next work.

〔The invention's effect〕

As described above, according to the present invention, the supplied mud is mechanically diffused in the width direction of the cloth, so that even a mud having a high viscosity can be surely diffused, and the mud can be spread on the cloth. Since this uniformly dispersed mud is supplied while the diffuser moves, it is possible to evenly supply the mud across one surface of the cloth. It is possible to completely solve problems such as the accumulation of highly viscous mud matter in one place, which has been a problem in filters.
