Abstract

PROBLEM TO BE SOLVED: To filter a liquid filter device using a filter paper by setting a bag-like filter paper inside a wire mesh container and putting a liquid to be filtered therein. However, since the mesh of the metal mesh is formed by knitting thin metal wires alternately up and down, there are uneven portions of various shapes, and a portion where strong force is applied to the filter paper appears. It was easy to get a hole.
SOLUTION: A liquid 2 to be filtered in a container 3 is sucked out by a flow rate control unit 6 including a pump 8 and supplied to a filtration tank 10 for filtration. The filtered liquid is taken out from the pipe 25. The inner basket 21 suspended from the flange 20 in the filtration tank 10 is made of metal or plastic having a smooth surface, and a large number of pores are opened in the side wall. The filter paper 22 is set inside thereof, and an auxiliary agent 23 is used as necessary. When the liquid to be filtered is put, the filter paper 22 is attached to the inner wall of the inner basket 21 having a smooth surface, so that a strong force is not partially applied and is not torn.

Description

  The present invention relates to a liquid filtration device that removes solid impurities with filter paper.

Removal of solid impurities mixed in a liquid is widely performed in various fields. For example, oil used for making fries by cooking is gradually mixed with solid impurities when fried. If the fly is fried without removing it, the fried condition of the fly will deteriorate, so that solid impurities are removed as needed.
One principle for removal is to scrape with a mesh of mesh that is smaller than the size of the solid impurities to be removed. For example, the liquid is removed by passing it through a wire mesh or a cage.
However, there is a limit to the size of the wire mesh or mesh basket, and it cannot be made very small. Therefore, when it is desired to remove even small solid impurities below the limit, filter paper is used.

FIG. 8 is a diagram showing a conventional liquid filtration device. In FIG. 8, 29 is a liquid filtration device, 30 is a liquid, 31 is a container, 32 is a pipe, 33 is a valve, 34 is a wire mesh, 35 is a container, 36 is a wire mesh container, 37 is filter paper, 38 is a pipe, 39 is A valve 40 is a container.
The first container 31 is a container for supplying the liquid 30 contained therein for a predetermined use. For example, the liquid 30 is oil for frying and the container 31 is a fryer. A liquid discharge pipe 32 and a valve 33 are provided below the container 31.

The metal mesh 34 is for roughly removing large-sized solid impurities (eg, weathering).
First, a wire mesh container 36 is set in the central container 35, and a bag-like filter paper 37 is spread on the inside thereof. Note that the wire mesh container 36 in this case is used to support the filter paper 37 in the form of a bag and to allow the filtered liquid to pass through, and the mesh of the wire mesh (for example, a mesh of about 3 mm square). ) Is not used because it tries to scrape solid impurities. The liquid to be filtered is put on the filter paper 37. A liquid discharge pipe 38 and a valve 39 are also provided at the lower portion of the container 35.
The last container 40 is a container for storing the filtered liquid 30.

Filtration is performed as follows.
(1) A wire mesh 34 is placed under the outlet of the pipe 32 with the valve 33, a container 35 in which a filter paper 37 or the like is set is placed thereunder, and the valve 33 is opened. The liquid 30 is put into the container 35 through the pipe 32.
(2) The liquid 30 is filtered by the filter paper 37. The solid impurities remain in the bag-like filter paper 37, and the filtered liquid passes through the eyes of the wire mesh container 36 and goes out of it.
(3) The container 40 is placed under the outlet of the pipe 38 with the valve 39 and the valve 39 is opened. Then, the liquid 30 that has come out of the wire mesh container 36 of the container 35 is put into the container 40.
(4) The liquid 30 that has come out of the container 40 is a liquid in which solid impurities are removed by the filter paper 37 and can be used in the container 31. Therefore, as indicated by the arrow 41, the container 31 is put into use again.

The conventional liquid filtration apparatus described above has a problem that the filter paper is immediately lost. That is, when a bag-like filter paper 37 is set inside the wire mesh container 36 and a liquid to be filtered is put therein, the filter paper 37 is pressed against the wire mesh by the pressure of the liquid. However, as is well known, the mesh of the metal mesh is formed by knitting thin metal wires alternately up and down, and therefore there are uneven portions of various shapes. Due to the uneven portions, the force applied to the filter paper became unbalanced, and it was actually the case that a hole was opened in the filter paper before it was used. Therefore, the consumption of the filter paper was severe. In addition, if the hole was opened, the filtration was not performed normally. Therefore, the filtration had to be repeated. In the past, this situation often occurred.
This invention makes it a subject to solve the above problems.

In order to solve the above-mentioned problem, in the present invention, in a liquid filtration device for supplying a liquid to be filtered to a filtration tank and filtering the liquid, the filtration tank has an inlet for introducing the liquid to be filtered on the upper wall surface. The lower part of the tank is connected to a pipe for discharging the filtered liquid, the inner wall is provided with a lower part of the tank, and the upper part of the tank is detachably joined to the lower part of the tank by a stopper. In the lower part of the tank, the following is accommodated.
(1) A cylindrical side wall portion having a smooth surface with a large number of holes in the wall surface, a horizontal edge portion provided at the upper end of the cylindrical side wall portion for locking to the flange portion, and a through hole in the center An inner basket which is formed of a bottom portion which is opened and is accommodated in the lower portion of the tank.
(2) A flat inner cage lid main body having a hole in the center, a guide pipe planted downward so that the central hole and the interior can pass, and a handle provided on the upper surface of the inner basket lid main body The inner pig that consists of
(3) Pull-up rod main body provided with a spiral flow-down guide portion, a valve body attached to the lower part of the pull-up rod main body, and extending below the valve body and loosely inserted into the hole A pull-up bar comprising a threaded portion into which a nut is fitted, and loosened with the nut so that it can be swung up and down.
In the liquid filtration apparatus having such a configuration, a rectangular filter paper is rolled into a cylindrical shape and set so as to be in contact with the inner wall of the inner basket, and the liquid to be filtered introduced into the tank is put through the central hole. The filtered liquid comes out from the hole in the side wall.

As for the bottom of the inner basket, the periphery may be fixed to the inner wall of the cylindrical side wall as a horizontal bottom shoulder, the center portion may be recessed to form a curved bottom, and a hole may be formed in the center.
The pull-up bar is not essential and can be omitted. When the pull-up bar is omitted, the hole in the bottom of the inner cage and the guide tube portion of the inner cage lid can be omitted accordingly. Further, an odor absorbing material can be installed in the upper part of the tank as required.

  According to the liquid filtration device of the present invention, the filter paper is set in the inner basket formed of a smooth member (metal or plastic) having many pores (about 2 mmφ), so the filter paper is It becomes a shape that can be stuck to a smooth surface. For this reason, a strong force is not partially applied, and a hole is not formed in the filter paper.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a diagram showing a liquid filtration apparatus according to the present invention. In FIG. 1, 1 is a liquid filtration device, 2 is a liquid, 3 is a container, 4 is a filter, 5 is a pipe, 5A is an inlet, 6 is a flow control unit, 6-1 and 6-2 are flow paths, and 7 is a flow path. Valve, 8 is a pump, 9 is a motor, 9-1 is a power supply terminal, 10 is a filtration tank, 11 is an upper part of the tank, 12 is a suspension support bar, 13 is a support plate, 14 is an odor absorber, 15 is a thumbscrew, 16 Is a stopper, 17 is a tank lower part, 18 is a lifting rod, 19 is an inner basket lid, 20 is a collar, 21 is an inner basket, 22 is a filter paper, 23 is an auxiliary, 24 is a nut, 25 is a pipe, 26 Is a valve, 183 is a valve body, and 194 is a guide tube portion.

The liquid 2 in the container 3 is a liquid to be filtered, that is, a liquid in which solid impurities are mixed. The liquid 2 is filtered through the path of the container 3 → the flow rate control unit 6 → the filtration tank 10. The liquid before filtration flows through the pipe 5, and the liquid after filtration flows through the pipe 25. This will be described in detail below.
A filter 4 is attached to the inlet of a pipe 5 for taking out the liquid 2 in the container 3. The filter 4 is for preventing coarse solid impurities from entering the pipe 5. Coarse solid impurities remaining in the container 3 can be easily removed by scooping with a wire mesh or the like. In this liquid filtration device, fine solid impurities that pass through the filter 4 are filtered.

The flow rate control unit 6 is a part that controls the flow rate of the liquid 2 taken out from the container 3. In the illustrated example, the flow path 5-1 in which the valve 7 capable of controlling the opening degree is installed and the flow path 5-2 in which the pump 8 is installed are connected in parallel. The pump 8 is driven by a motor 9, and power to the motor 9 is supplied from a power supply terminal 9-1.
The liquid 2 in the container 3 is sucked out by the suction force of the pump 8, but its flow rate is controlled by controlling the opening degree of the valve 7 (when the opening degree is made small, the entire flow rate increases and the flow rate increases). Increasing the degree reduces the overall flow rate.)

The filtration tank 10 is roughly composed of a tank upper part 11 and a tank lower part 17, both of which are detachably combined with a stopper 16, and the inside is sealed. When cleaning the inside of the filtration tank 10 (for example, replacement of the odor absorbing material 14 and replacement of the filter paper 22), the tank upper portion 11 is removed.
The tank upper part 11 is provided with a structure for removing odors. A suspension support bar 12 is attached to the internal ceiling of the tank upper part 11. A support plate 13 is first inserted into the lower end of the suspension support bar 12, and a butterfly screw 15 is screwed into the support plate 13. The thumbscrew 15 prevents the support plate 13 from falling. The support plate 13 is for supporting the odor absorbing material 14 (eg, bamboo charcoal, activated carbon, etc.) on it.

  FIG. 7 is a view showing an example of the support plate 13 used in the present invention. 131 is a support plate body, 132 is a hole, and 133 is a support rod insertion hole. The support rod insertion hole 133 is a hole for inserting the suspension support rod 12 described above. The holes 132 are pores for allowing the liquid 2 to be filtered to flow, and are provided in the support plate body 131 in large numbers. As indicated by arrows in FIG. 1, the liquid to be filtered enters the upper part through the hole 132 from the lower side of the support plate 13, is removed from the odor by contacting the odor absorbing material 14, and again passes through the hole 132. Come out.

A structure for filtering solid impurities is provided in the tank lower portion 17. First, the outline will be explained. A flange 20 is provided on the inner wall at a position below the inflow port 5 </ b> A shown in FIG. 1, and the inner basket 21 is locked to the flange 20. The inner basket 21 is covered with the inner basket 19. A guide tube portion 194 is provided at the center of the inner basket lid 19, and the pull-up bar 18 is inserted therein, and the tip thereof is screwed to the bottom portion of the inner cage 21.
When performing filtration, the tank upper part 11 is removed, the inner basket lid 19 is removed, and the filter paper 22 is set so as to contact the inner wall of the inner basket 21. Then, an appropriate amount of auxiliary agent 23 (for example, made of cellulose, diatomaceous earth, etc.) is put into the bottom of the inner basket 21, and the inner basket lid 19 and the tank upper portion 11 are returned to their original positions.

2A and 2B are views showing the inner basket 21 used in the present invention. FIG. 2A is a perspective view and FIG. 2B is a cross-sectional view. In FIG. 2, 210 is an edge, 211 is a cylindrical side wall, 212 is a hole, 213 is a curved bottom, 214 is a punched hole, and 215 is a bottom shoulder.
The inner basket 21 has a cylindrical side wall portion 211 and a curved bottom portion 213, and an edge portion 210 extends horizontally at the upper end of the side wall. This edge portion 210 is used for locking to the flange portion 20 of FIG. A hole 214 is formed in the center of the curved bottom portion 213, and the vicinity of the periphery of the curved bottom portion 213 is horizontal to form a bottom shoulder 215. The extraction hole 214 is a hole for removing dust accumulated in the inner basket 21, and the lower end of the pull-up bar 18 of FIG. 1 is loosely inserted. The filter paper 22 of FIG. 1 is stood on the bottom shoulder 215.

A large number of holes 212 are formed in a portion of the side wall of the cylindrical side wall portion 211 above the position of the bottom shoulder 215. This hole is a hole for discharging the liquid that has passed through the filter paper 22 to the outside of the inner basket 21 (about 2 mmφ).
The inner cage 21 is made of metal or plastic. The hole 212 is opened by punching in the case of metal, and is formed by pre-molding in the case of plastic.

  FIG. 3 is a view showing the filter paper 22 used in the present invention. FIG. 3 (1) shows a state before use, and FIG. 3 (2) shows a state during use. In the present invention, a rectangular filter paper 22 having a simple shape can be used. The vertical length of the rectangle is set to the length from the bottom shoulder 215 to the upper end of the inner basket 21. Such a filter paper 22 is rolled into a cylindrical shape as shown in FIG. 3 (2) and stood on the bottom shoulder 215 of the inner basket 21. When the liquid to be filtered is put therein, the filter paper 22 is pushed outward by the liquid and spreads outward, and touches the inner wall of the smooth surface of the inner basket 21.

FIG. 4 is a view showing the pulling bar 18 used in the present invention. In FIG. 4, reference numeral 181 denotes a pull-up rod body, 182 denotes a spiral flow lower guide portion, 183 denotes a valve body, and 184 denotes a screw portion. The pull-up bar 18 includes a pull-up bar main body 181, a valve body 183, and a screw portion 184. The valve body 183 is provided below the pull-up rod body 181, and the screw part 184 is provided below the valve body 183. The pulling rod main body 181 is provided with a spiral flow guide part 182.
FIG. 4 (1) shows an example in which the pulling rod main body 181 is formed with a round bar, and FIG. 4 (2) shows an example in which it is formed with an elongated flat plate.

First, the example of FIG. 4 (1) is demonstrated. In this example, a spiral groove is provided on the peripheral surface of the pull-up bar main body 181 made of a round bar, and this is used as a spiral flow guide part 182. As shown in FIG. 1, the pull-up rod 18 is inserted into the guide tube portion 194, but when liquid is introduced from above the guide tube portion 194, the liquid flowing down around the pull-up rod 18 is The flow is guided by the spiral flow guide portion 182 and flows down while rotating spirally.
The valve body 183 is a valve body for closing the hole 214 of the inner basket 21. The threaded portion 184 is loosely inserted into the extraction hole 214, and the nut 24 shown in FIG. By tightening the nut 24, the valve body 183 firmly closes the hole 214.
Next, an example of FIG. 4 (2) will be described. In this example, the spiral flow lower guide portion 182 is formed by twisting an elongated flat plate. This can be manufactured at a lower cost than that of FIG. The other parts are the same as in the example of FIG.

5A and 5B are views showing the inner basket 19 used in the present invention. FIG. 5A is a perspective view and FIG. 5B is a cross-sectional view. In FIG. 5, reference numeral 191 denotes an inner basket lid body, 192 denotes a central hole, 193 denotes a handle, and 194 denotes a guide tube portion. The inner lid body 191 is on a disc having a central hole 192 in the center, a guide tube portion 194 is planted below the center portion, and a handle 193 is planted above the center portion. Yes. In addition, although the shape of the handle 193 is drawn as a cylindrical thing with an edge part, it is not necessarily limited to this shape. Other shapes may be used as long as the handle for lifting the lid is fulfilled.
As shown in FIG. 1, the inner basket lid 19 is placed on the inner basket 21, and the pulling rod 18 is inserted into the central hole 192. As described above, the lower end of the pull-up bar 18 is taken out from the hole 214 at the bottom of the inner basket 21 and attached to the curved bottom 213 by the nut 24. If it does so, a clearance gap will be made between the inner wall of the induction | guidance | derivation pipe | tube part 194 and the pull-up stick | rod 18, but the liquid which should be filtered will be put there.

FIG. 6 is a view for explaining the operation of the pull-up bar 18. The pull-up bar 18 has mainly two functions.
The first action is that the liquid flows down in a spiral. By flowing down spirally, the flow can be adjusted and flowed quickly, and the auxiliary agent 23 that tends to accumulate at the bottom of the curved bottom portion 213 can be evenly diffused to the periphery. When evenly diffusing, it adheres evenly to the inner wall of the cylindrical filter paper 22 and is convenient for filtration.
The second action is an action of removing dust accumulated on the curved bottom 213 of the inner basket 21. This operation will be described with reference to FIG.

FIG. 6 (1) shows a state before dust is removed, and FIG. 6 (2) shows a state where dust is being removed. The reference numerals correspond to those in FIGS.
In FIG. 6 (1), the new inflow of the liquid to be filtered is stopped, and the filtration is completed. The filtered liquid remaining in the tank lower part 17 is also gradually discharged through the pipe 25 over time. In such a case, the auxiliary 23 that has not adhered to the filter paper 22 or the solid impurities remaining inside due to the filtration accumulates as dust on the curved bottom portion 213.
Therefore, when the nut 24 is twisted in the direction in which the upper end of the pull-up bar 18 is loosened, the tightening force by the nut 24 is lost, the valve body 183 is separated from the hole 214, and the hole 214 is connected. If the twisting is continued further, as shown in FIG. 6B, the position of the nut 24 is further away from the valve body 183, and the pulling rod 18 can be swung up and down. When it is shaken up and down, the accumulated dust goes out from the hole 214 with the liquid.

The liquid filtration device of the present invention is constituted by the above-described parts. It is as follows when the procedure of filtration work is demonstrated collectively (refer FIG. 1 etc.).
(1) Preparation regarding the tank upper part 11: The tank upper part 11 is removed, and the odor absorbing material 14 is attached.
(2) Preparation for tank lower part 17: The inner basket lid 19 is removed, and the filter paper 22 is rolled as shown in FIG. 3 (2) and set inside the inner basket 21. If necessary, the auxiliary agent 23 is put into the inner basket 21 (if the auxiliary agent 23 is used, solid impurities of about 1 micron or more can be removed, and filtration called “microfiltration” can be realized. If no auxiliary is used, solid impurities larger than the mesh size (about 7 microns) of the filter paper 22 can be removed. Finally, the inner basket 19 is set.

(3) Preparation concerning the filtration tank 10 ... The tank upper part 11 is piled up on the tank lower part 17, and it stops with the fastener 16 and unites.
(4) Suctioning out the liquid 2 to be filtered: The motor 9 drives the pump 8 of the flow rate control unit 6 to suck out the liquid 2 in the container 3 and supply it to the filtration tank 10.
(5) Flow of the liquid 2 in the filtration tank 10 ... The liquid 2 flowing in from the inflow port 5A fills the filtration tank 10. The liquid 2 comes into contact with the odor absorbing material 14 and is deodorized, and is guided to the spiral flow guide part 182 of the pull-up bar 18 from the central hole of the inner basket lid 19 and flows down in a spiral shape. The auxiliary 23 put in the curved bottom 213 of the inner basket 21 is wound up in a spiral shape and uniformly diffused, and adheres to the inner surface of the filter paper 22.

(6) Filtration action: The liquid 2 is filtered by the auxiliary 23 and the filter paper 22. The filtered liquid 2 goes out through a hole 212 formed in the inner basket 21. The liquid 2 that has flown out can be continuously reused by continuously returning it to the container 3 through the pipe 25, or the valve 26 attached to the pipe 25 is opened and stored in a container (not shown). You can also keep it.
(7) Garbage treatment after filtration: The upper end of the pull-up rod 18 is twisted to loosen the nut 24, and when the gap between the valve body 183 and the nut 24 is opened, the pull-up rod 18 is shaken in the vertical direction. The dust accumulated in the curved bottom portion 213 is discharged to the outside through the hole 214.

By the way, the filter paper 22 set inside the inner basket 21 as described above is not torn even if it is used a considerable number of times. Although the filter paper 37 of the conventional liquid filtration apparatus demonstrated in FIG. 8 will be torn immediately, there is a marked difference compared with it.
This is because the inner basket 21 having a structure in which a large number of pores are opened on a smooth surface is used as a structure part that makes the filter paper 22 contact and allows the filtered liquid to pass through. That is, since the filter paper 22 is brought into close contact with a smooth surface, even if it receives a pressing force by the liquid, the force is not partially applied or weakly applied. Therefore, it is hardly broken. Therefore, it does not lead to a situation where filtration has to be performed again.

The following components can be omitted as necessary.
(1) Odor-absorbing material 14 ... The odor of the liquid 2 to be filtered is not so bad and it can be omitted if it is not necessary to deodorize.
(2) Pull-up bar 18... When the auxiliary agent 23 is used in combination, the residue occupies the main part of the dust, so the pull-up bar 18 is necessary to remove it. However, the pull-up bar 18 can be omitted when the auxiliary agent 23 is not used together or when the liquid is a kind of liquid that does not collect much dust.
(3) Guide tube portion 194... This is combined with the spiral flow lower guide portion 182 of the pull-up rod 18 to generate a spiral flow. Can also be omitted.
(4) Punching hole 214... This is for discharging dust by shaking the pulling bar 18 up and down, so that it can be omitted when the pulling bar 18 is omitted.
(5) Curved bottom portion 213... The reason why the curved bottom portion 213 is curved is that when the liquid flowing down the spiral rolls up the auxiliary agent 23 and diffuses, the dust gathers near the hole 214 at the bottom center. This is to make it easier. Accordingly, when the pull-up bar 18 is omitted, it is not necessary to bend it and a flat bottom can be obtained.
