The present invention relates to a grease feeder of a bishopcon cylinder box wet damping dust in blast furnace gas, and more particularly, it is impossible to estimate the filling amount of grease during grease feeding. The present invention relates to a grease feeder of a bishopcon cylinder box improved to prevent leakage of dust collection.

In general, a large amount of dust and water is contained in the blast furnace gas generated in the blast furnace (blast furnace) of the steel mill, Bischoff (BISCHOFF CONE) is used as a facility for wet vibration dampening.

Conventionally, the dust removal equipment is blast furnace gas generated in the blast furnace as shown in FIG. 1 is introduced into the bishop (1) and is stagnated by the scrubber (S) while stagnating therein, the charged gas outlet (H) After being moved to the lower side of the bishop (1) through the outlet 4 was designed to be supplied to the power plant.

At this time, the outlet (H) is a conical bishop cone (2) is installed and configured to selectively open and close the bar, the rod (3) is connected to the lower end of the bishop cone (2) and the rod (3) It is connected to the hydraulic cylinder (8) for raising and lowering operation, and installed the cylinder box (5) to prevent the smooth operation of the rod (3) and the leakage of gas in the bishop (1) and causes the rod (3) to Exposed to penetrate the cylinder box (5) and then filled with lubricating oil such as grease, the rod (3) is raised and lowered as the bishop cone (2) to open and close the outlet (H) by dust removal of the gas discharged from the blast furnace Only clean gas was allowed to flow into the power plant.

However, since the grease filled in the cylinder box 5 is exhausted by the operation of the rod 3, periodic filling was required, which means that the cylinder box 5 having a volume of about 200 liters at every regular repair by the operator. It has been replenished by filling the grease through the feed pump 7 inside.

However, despite the need to charge while checking the amount of grease, to confirm the charge, two workers dismantle the large manhole (9) for several hours, and then observe and observe the cumbersome work relationship roll charge that must be tightened again. Predictive charging is performed without confirmation, so accurate charging is difficult and constant overcharging occurs. Grease leaks between the cover 6, which seals the cylinder box 5, overflows to the outside, and flows into the chic or pond. It turned into oil and introduced into the drainage during the substitution work, causing serious environmental pollution.

In addition, if the amount of grease is insufficient due to the leakage caused by the overcharging of the grease as described above, the dust containing gas and a large amount of dust leaks through the lower part of the cylinder box (5), not only equipment pollution but also There was also the risk of a safety accident causing harm.

The present invention has been made in view of the above-mentioned problems of the prior art, and has been created to solve this problem. The hydraulic circuit is configured in the cylinder box and automatically drives the feed pump according to the hydraulic fluctuation therein. By setting the lower limit to prevent overcharging of the grease, Bishop does not need to be fixed for several hours to feed the grease, but also prevents environmental pollution and eliminates the risk of safety accidents such as gas poisoning. The object is to provide a grease feeder for a cone cylinder box.

The above object of the present invention, the cylinder box 100 is fixed to the bishop (1), which is a wet vibration damping equipment, the upper end has a large diameter in the form of a flange and the disk-shaped guide groove 130 is empty; A pressure detector 200 installed and connected to a lower outer circumferential surface of the cylinder box 100 and filled with nitrogen gas therein; A pressure transmitter 220 for detecting a nitrogen gas pressure change charged in the pressure detector 200, comparing the detected pressure value with a set value, and outputting a low signal or a high signal; At the time of outputting the high signal of the pressure transmitter 220, the driving signal is stopped by receiving the stop signal of the pump stop circuit according to the high signal, and at the time of outputting the low signal of the pressure transmitter 220, the pump start circuit according to the low signal. A feed pump 170 which is started to receive a start signal of the feeder to be supplied and charged with grease into the cylinder box 100; A ring plate 120 which is built in the cylinder box 100 and opens and closes the guide groove 130 while being lowered according to the amount of grease filled in the cylinder box 100; A spring 122 interposed between the upper end surface of the ring plate 120 and the upper inner wall surface of the cylinder box 100 to apply a pressure to the ring plate 120; An overflow pipe 160 communicating with one side of an outer circumferential surface of the guide groove 130 to discharge grease overflowed into the guide groove 130; And a collection container (150) provided at an end side of the overflow tube (160) to collect grease discharged by the overflow tube (160). By providing a paper feeder.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

2 is a cross-sectional view showing main parts of a paper feeding device according to the present invention, FIG. 3 is a perspective view of a partially cut away portion of the paper feeding device of the present invention, and FIG. 4 is a control circuit diagram of a pressure detector for controlling the paper feeding device of the present invention.                     

As shown in Figure 2 and 3, the cylinder box 100 is fixed to the bishop (1) as before, the pressure detection pipe 210 through which it is possible to communicate through the lower outer peripheral surface of the cylinder box 100 is disposed The pressure detector 200 is installed at an end of the pressure detection pipe 210.

The pressure detector 200 is provided with a pressure transmitter 220 at the top, the pressure transmitter 220 detects the pressure fluctuation of the nitrogen gas charged in the upper portion of the pressure detector 200 and the detected pressure value is a set value It determines whether it is larger or smaller and outputs the low signal S1 or the high signal S2 as shown in FIGS. 4A and 4B.

When the high signal S2 is generated, the pump stop circuit sends a stop signal to stop the drive of the feed pump 170. When the low signal S1 occurs, the pump start circuit sends a start signal to supply the feed pump ( It is controlled to start the drive of 170.

At this time, the generation set pressure of the low signal S1 is, for example, when the nitrogen pressure by the grease charged in the cylinder box 100 is 2 kg / cm 2 or less, and the generation set pressure of the high signal S2 is 5 kg / cm 2 or more. Can be set to the case. Here, the set pressure may vary depending on the capacity of the cylinder box 100 and is merely an example.

In addition, a feed pipe 172 connected to the feed pump 170 is installed at one side of the central portion of the cylinder box 100 as in the conventional manner, and the flange of the upper end of the cylinder box 100 at a predetermined length downward from the upper end thereof. The diameter of the shape is enlarged and the disc-shaped guide groove 130 is empty inside.                     

In addition, a ring plate 120 is inserted into the cylinder box 100 which is a kind of piston that is larger than the width of the guide groove 130 and substantially matches the inner diameter.

One end of the spring 122 is fixed to the top surface of the ring plate 120, and the other end of the spring 122 is fixed to the top inner wall surface of the cylinder box 100.

Therefore, the ring plate 120 is to be raised by the pressure of the grease received from the lower end surface side, while being pressed by the spring 122, while maintaining the guide groove 130 while maintaining parallel at the appropriate time It will open and close.

In this case, in order to prevent a large number of falling of the ring plate 120, it is more preferable to form a locking step 124 on the inner circumferential surface of the adjacent lower cylinder box 100 in which the guide groove 130 is formed.

This, it is reasonable to lay in order to prevent the ring plate 120 is interlocked while the operation rod 110 is raised and lowered so as to faithfully perform the original function of the ring plate 120.

In addition, a sealing member 102 is installed at the lead-out portion of the operation rod 110, which is the upper surface of the cylinder box 100, to close it tightly.

On the other hand, one side of the outer circumferential surface of the guide groove 130, the overflow pipe 160 is connected to the communication pipe, a part of the check valve 140 is installed, the extended end is provided with a collection container 150.

Although not shown, the collection container 150 is more preferably installed so as to recycle the overflow grease by communicating pipe back to the feed pump 170 side.                     

The operating relationship of the present invention made of such a configuration is as follows.

First, when the grease filled in the cylinder box 100 is sufficient and there is no change of nitrogen pressure on the pressure detector 200 through the grease, as shown in FIG. The pressure pushed by the grease and the spring 122 are in balance, that is, the ring plate 120 is closed to maintain the guide groove 130 so that the grease cannot be discharged to the overflow pipe 160.

In this state, if grease is consumed according to the operation of the operation rod 110 and the amount of grease is insufficient, the pressure of the spring 122 is strong, so that the ring plate 120 is guide groove as shown in FIG. It is lowered to a position lower than 130.

Therefore, the pressure of grease that is in equilibrium with the nitrogen pressure in the pressure detector 200 is broken, and the grease that has flowed into the pressure detector 200 is pushed by the nitrogen pressure and rides on the pressure detection pipe 210 through the cylinder. When the nitrogen pressure falls to the inside of the box 100, and the nitrogen pressure drops at the set value, for example, 2 kg / cm 2 or less, the pressure transmitter 220 generates a low signal S1 to supply the feed pump 170. Will be driven.

The grease is charged into the cylinder box 100 by the feed pipe 172 by driving the feed pump 170.

When the pressure of the grease increases by overcharging during charging, as shown in (c) of FIG. 5, the pressure of the spring 122 is overcome and the ring plate 120 is pushed up to open the guide groove 122. At the same time, since the amount of grease is increased in the pressure detector 200, high pressure is applied.

The grease overflowed through the guide groove 130 is collected to the collection vessel 150 through the overflow tube 160. Since the check tube 140 is installed in the overflow tube 160, the collection vessel ( The backflow of the grease on 150) is prevented.

In addition, when nitrogen pressure is detected at a high pressure, for example, 5 kg / cm 2 or more, the pressure detector 200 outputs a grease by stopping the start of the feed pump 170 while outputting a high signal S2 by the pressure transmitter 220. Will stop.

While repeating the above process continuously, the inside of the cylinder box 100 always maintains a certain amount of grease charged state, thereby enabling a smooth operation without leakage of grease.

As described in detail above, the present invention is collected in a separate container through the overflow tube even if the grease is overcharged, so that it does not mix with the dust collection inside the bishop to prevent environmental pollution, and when the grease is not charged automatically detects it quickly Recharging provides a very useful effect of eliminating the risk of safety accidents caused by gas leakage.
