Description

Filtering Pipe for Diaphragm of Air Operation Diaphragm Pump

The present invention relates to an air-driven diaphragm pump, and more particularly, to a diaphragm protection filtering pipe of an air-driven diaphragm pump for preventing the diaphragm from being damaged due to iron pieces flowing into the diaphragm pump.

Conventional air-driven diaphragm pump refers to a pump that transfers fluid by compressing and relaxing a circular diaphragm mounted inside the pump by air pressure. Chemical, mining, shipping, filter press, and sludge transfer It is applied to various fields.

An example of such an air driven diaphragm pump is illustrated in the accompanying drawings, in which the diaphragm 100 is made of a very flexible material that can be easily operated by the pressure of air.

Thus, the diaphragm 100 made of a very flexible material may be easily damaged by foreign matter introduced during the transport of the fluid.

For example, in the wastewater treatment process, the sedimentation tank or the concentration tank has an open shape outside, and the scraper is rotated by the reducer in the inside, and therefore, due to various constructions or corrosion from parts such as iron railings. Fallen iron pieces are more likely to enter the wastewater sludge, which often flows into the diaphragm pump and damages the diaphragm.

In this way, if the diaphragm is damaged, not only the function of the pump is lost, but also the expensive diaphragm needs to be replaced, resulting in a loss of operation work and an increase in operating costs.

The present invention has been made to solve the problems described above, to provide a diaphragm protection filtering pipe of the air-driven diaphragm pump for preventing the diaphragm from being damaged by foreign matter such as iron pieces flowing into the air-driven diaphragm pump. Has its purpose.

Filtering pipe for diaphragm protection of the air-driven diaphragm pump according to the present invention for achieving the above object, in the air-driven diaphragm pump for transferring the liquid through the pipe, the non-magnetic material having a fastening end for fastening to the pipe Cladding tube; And a magnetization pipe made of a magnetization body and disposed on an inner surface portion of the cladding tube.

Here, the magnetization pipe is characterized in that consisting of a permanent magnet or an electromagnet.

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

Figure 2 is a perspective view showing a filtering pipe according to the present invention, the structure is the same as or similar to the conventional pipe, the cover pipe is formed on both ends of the fastening end (11a) for fastening to the pipe toward the diaphragm pump side (11) and the magnetization pipe 12 enclosed by this cladding pipe 11 are the characteristics comprised internally.

In particular, the cladding tube 11 is made of a nonmagnetic material made of a metal such as austenitic stainless steel, or a non-metallic material, so that it is not magnetized when exposed to a magnetic field.

In addition, the magnetization pipe 12 is made of a magnet commonly referred to as, or a material that is magnetized by the magnetic field to become ferromagnetic.

More specific embodiments of the present invention are shown in FIGS. 3 and 4.

FIG. 3 shows an example in which the magnetization pipe 12 of the filtering pipe 10 is made of one permanent magnet, and FIG. 4 shows that the magnetization pipe 12 ′ is wound around the coil 13 on the outer circumferential surface of the magnetic pipe. The example which consists of an electromagnet which shows ferromagneticity by an electric current supply is shown.

In this case, when the magnetizing pipe 12 'is made of an electromagnet, a device capable of conducting an electric current to the coil 13 wound on the outer circumferential surface of the pipe is provided separately. Such an energizing device can be easily found in a conventional electromagnet facility. As such, detailed description thereof will be omitted.

Meanwhile, as the magnetization pipes 12 and 12 'are made of permanent magnets or electromagnets, there is a need for a means for preventing magnetic foreign substances from adhering to the outer circumferential surface of the magnetization pipes 12 and 12' from the external environment. The cladding pipes 11 and 11 'made of nonmagnetic material play this role.

The use state diagram in which the filtering pipe of the present invention thus constructed is installed and used in the pipe facing the diaphragm pump side is illustrated in FIG. 5.

5 shows the application of the embodiment in which the magnetization pipe 10 is made of one permanent magnet. The same applies to the case of the magnetization pipe 10 'made of electromagnets. Therefore, only the former case will be described.

In addition, here, it demonstrates according to the example applied in the field of removing heavy metal in acid alkaline wastewater by the hydroxide precipitation method in wastewater treatment process.

In other words, the wastewater treatment process by the hydroxide precipitation method is processed in the order of neutralization tank → oxidation tank → coagulation tank → sedimentation tank → concentration tank → filter press → sludge removal on the cake, the air-driven diaphragm pump from the concentration tank to the filter press Used to transport sludge.

In particular, the filtering pipes 10 and 10 'of the present invention are interposed between the conduit connecting the concentrating tank and the pneumatic diaphragm pump, as shown in FIG. 5, the first pipe 20 and the second pipe 30. The iron pieces 40 included in the fluid flowing from the first pipe 20 to the second pipe 30 in a state in which the filtering pipe 10 is fastened by fastening means such as bolts at the fastening end 11a thereof. Filtered out.

That is, the first pipe 20 may include the iron pieces 40 introduced from the surrounding environment as described above, when the introduced iron pieces 40 reach the filtering pipe 10 of the magnetization pipe 12. It is attracted to the magnetic force and attached to the inner wall of the magnetization pipe 12.

Therefore, most of the iron pieces 40 are filtered by the magnetization pipe 12 before the fluid reaches the second pipe 30 directly connected to the diaphragm pump, so that the iron pieces 40 do not flow into the diaphragm pump. To prevent damage.

In the above description, the present invention has been described only in relation to the example applied in the wastewater treatment process. However, the present invention is applicable to all industries in which an air-driven diaphragm pump is used, such as chemical, mining, paint, shipping, chemicals, filter press, and sludge transfer. It will be possible.

As described above, the diaphragm protection filtering pipe of the air-driven diaphragm pump according to the present invention filters the iron pieces flowing in the process in which the fluid is transferred to the diaphragm pump, thereby preventing the damage of the diaphragm constituting the diaphragm pump life of the diaphragm Extension and consequent cost savings are available.
