(Field of Industrial Application) The present invention relates to a filtration device that filters an undiluted solution by passing it through a main body with a built-in filter element. Used to remove certain solids. (Prior Art) As a conventional filtering device of this type, there is one shown in FIG. This one has an inlet pipe d that introduces a stock solution c into a main body b that has a filter element a.
The outlet pipe f for discharging the liquid and the filtrate e is connected in a straight shape. (Problem to be solved by the invention) When the inlet pipe d is connected to the main body b in a straight state, the flow of the stock solution c flowing into the main body b from the inlet pipe d is shown by the streamline g in the figure. As a result, a diameter reduction phenomenon occurs in which the diameter of the inlet area to the main body b becomes smaller than the inner diameter of the inlet pipe d, accompanied by separation from the pipe wall and vortex flow.
This results in a large pressure loss and extremely reduces the effective filtration area of the filter element a. Furthermore, since the stock solution c reaches the filter element a at a high speed, the filter element a becomes excessively clogged, leading to an early decrease in filtration efficiency. In addition, the flow of the filtrate e from the main body b to the outlet pipe f connected in a straight state to the main body b is as shown by the streamline h in the figure, and the flow of the filtrate e from the main body b to the outlet pipe f is as shown by the streamline h in the figure. Although the area diameter is slightly larger than the inner diameter of the outlet pipe f, a diameter reduction phenomenon occurs immediately after entering the outlet pipe f, resulting in a pressure loss. Due to the outflow of the filtrate e having a large outflow area diameter, the undiluted solution flowing in from the inlet pipe d is drawn through the large diameter range, and the permeability of the undiluted solution through the filter element a is slightly expanded, but the extent of this is small. As a result of the above, the conventional apparatus has a large pressure loss and a small effective filtration area of the filter element, which tends to cause an early decrease in filtration efficiency due to excessive clogging of the filter element. (Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides at least one of the inlet and outlet of the main body in which the filter element is built into the main body, and the inner diameter of the main body is increased. It is characterized by being formed into a shape. (Function) The inlet or outlet formed in the shape of a rattle can cause eddy currents to be generated when liquid flows into the wide main body from a narrow pipe, or when filtrate flows out from the wide main body to a narrow pipe. It is possible to suppress the occurrence of peeling and contraction, and the pressure loss can be reduced accordingly. The inlet or outlet formed in the shape of a rattle enlarges the inlet area diameter of the raw liquid flowing into the wide body from the narrow conduit than the inlet diameter, and the inlet area diameter of the filtrate flowing from the wide body to the narrow conduit. The diameter of the outflow area can be further expanded than when the outlet is straight. Furthermore, the rate at which the stock solution reaches the filter element can be reduced by increasing the diameter of the inlet region, and excessive clogging of the filter element can be prevented accordingly. Further, according to the present invention, by making the inlet and the outlet protrude toward the main body and forming the protruding portions into a truss-like shape, the truss-shaped portions can be excluded from the constituent members of the pressure vessel, so that the wall thickness can be reduced. It is easy to mold and can reduce manufacturing costs. (Embodiment) To explain the first embodiment of the present invention shown in FIGS. An inlet pipe 5 for introducing the stock solution 4 into the chamber is connected, and an outlet pipe 6 for discharging the filtrate 7 into the other chamber.
is connected. An inlet 5a for the stock solution 4 through the main body 1 and the inlet pipe 5, and an outlet 6a for the filtrate 7 through the outlet pipe 6 of the main body 1
Both protrude into the main body 1 and are formed in a flap shape. This rattling shaped inlet 5a and outlet 6a are
Since it protrudes into the main body 1 and receives fluid pressure without much difference from both its inner and outer circumferences, the inside of the main body 1 becomes high pressure, but it does not need to have the same pressure resistance as the main body 1 and can be made thinner than the main body 1. It is easy to form into a round shape. Since the inlet 5a has a flat shape, the flow of the stock solution 4 flowing into the main body 1 from the inlet pipe 5 is as follows.
This flow line is as shown in the streamline 8 shown in the figure, and it flows into the main body 1 without disturbance, and it is wider than the inner diameter of the inlet pipe 5, and the diameter of the inlet region gradually increases as it approaches the filter element 3. As a result, compared to the conventional example having a streamline g, the pressure loss is small, and the effective filtration area of the filter element 3 can be significantly increased, which also alleviates the pressure loss. . Furthermore, the speed at which the stock solution 4 reaches the filter element 3 is reduced, and the problem of excessive clogging of the filter element 3 is eliminated. Furthermore, since the outlet 6a is shaped like a trumpet, the flow of the filtrate 7 flowing from the inside of the main body 1 into the outlet pipe 6 is as follows.
As shown in the streamline 9 shown in FIG. 2, it flows from the main body 1 to the outlet pipe 6 without any turbulence, and the peeling and diameter reduction phenomenon in the outlet pipe 6 as in the conventional example with streamline h is prevented. It doesn't happen. Also, compared to the case of streamline h, the filtrate 4 in the main body 1 is transferred from the main body 1 to the outlet pipe 6.
The diameter of the outflow area to the undiluted solution 4 is also large, and the flow of the stock solution 4 in the large diameter range is sucked as it is and passed through the filter element 3. Even if the diameter of the flow velocity is small, since it is sucked while expanding and passes through the filter element 3, the diameter of the inlet area of the stock solution 4 is expanded and the velocity is thereby reduced, and the effective filtration area of the filter element 3 is increased. be able to. The second embodiment of the present invention shown in FIGS. 3 and 4 is as follows:
A sub-chamber 11 having a larger diameter than the inlet pipe 5 is formed at the connection between the main body 1 and the inlet pipe 5, and the trumpet-shaped inlet 5a of the first embodiment is protruded from the sub-chamber 11. This is different from the first embodiment. In this case, the stock solution 4 entering the subchamber 11 from the inlet 5a
is subjected to the effect of expanding the diameter of the inflow region due to the tupular shape of the inlet 5a, and once it further expands to the full cross-section of the subchamber 11, it flows into the main body 1.
The diameter of the inflow region of the stock solution 4 into the main body 1 further increases and stabilizes, and the effective filtration area increases compared to the first embodiment, and the speed at which the stock solution 4 reaches the filter element 3 further decreases, resulting in a filter element. 3 makes it difficult to cause excessive clogging. In addition, as the effective filtration area of the filter element 3 increases, the filtration resistance becomes smaller, and the diameter of the inflow region of the stock solution 4 by the subchamber 11 increases, the distance between the inlet 5a and the filter element 3 increases, the flow velocity decreases, and the rupture occurs. The eddy flow prevention by the shaped inlet 5a allows the raw liquid 4 to flow smoothly into the main body 1, resulting in an even smaller overall pressure loss. A third embodiment of the invention, shown in FIG.
Only the outlet 6a is shaped like a protruding protrusion into the main body 1, and the outlet 6a is a straight outlet pipe 6 in the main body 1.

[Table] From the above, it is clear that the pressure loss is reduced by having the inlet 5a and the outlet 6a in a tangled shape. (Effects of the invention) According to the invention, at least one of the inlet of the stock solution and the outlet of the filtrate of the main body is made into a flat shape.
It has the characteristics that it does not generate eddy current when the stock solution flows into the main body, does not cause the filtrate to peel off from the inner surface of the outlet pipe when it flows out from the main body, and has the characteristics of The flow diameter is expanded and filtration resistance is reduced, reducing pressure loss and contributing to energy savings. In addition, the effective filtration area of the filter element is increased by an increase in the flow diameter when the stock solution passes through the filter element. Furthermore, the rate at which the undiluted solution reaches the filter element is reduced, and it is possible to prevent a decrease in the filtration function due to excessive clogging of the filter element. Furthermore, according to the present invention, by making the flap-shaped inlet/outlet protrude toward the inside of the main body, this flap-shaped part can be excluded from the constituent members of the pressure vessel, which facilitates molding and reduces manufacturing costs. can be reduced.
