Description

Grain washer

The present invention relates to a grain washer, and more particularly, to a grain washer that effectively removes foreign substances mixed in grains and enhances the washing effect.

Generally, grains, such as sesame seeds, beans, red beans, and rice, are mixed with foreign substances in the process of harvesting and storing them. Examples of such foreign matters include stones, sand, and straw. Therefore, in order to use it for food, it is necessary to remove and wash the foreign substances such as stones, sand, and straw. Grain cleaners have been used for this purpose.

1 schematically shows a grain washer according to the prior art. According to this, there is provided a washing tank 1 in which grains S are put in and washed. The bottom portion of the washing tank 1 is formed to be inclined toward the center so that the upper portion is wider and narrower toward the lower portion. In the washing tank 1, a flow pipe 2 is installed in which grains S and water W are mixed and moved. The upper end portion of the flow tube 2 is bent to face the inside of the washing tank (1). And the upper end portion of the flow tube 2 is configured to be rotatable to transfer the grain (S) and water (W) passed through the flow tube 2 to the outside of the washing tank (1).

In addition, the bottom of the washing tank (1) is provided with a spray nozzle (3) for injecting high pressure water into the flow pipe (2) provided in the washing tank (1). The injection nozzle 3 is connected to a pump 4 for pressurizing and delivering water from a separate water storage tank 5 to the injection nozzle 3.

In the drawings, reference numeral 6 denotes a foreign substance removal valve for removing the separated foreign substance A, and 7 is an emergency drain.

It looks at washing the grain (S) using a grain washer according to the prior art configured as described above. First, after the grain (S) to be washed into the washing tank (1), the high pressure water (W) is injected through the injection nozzle (3). When the high pressure water (W) is injected as described above, the grains (S) introduced into the washing tank (1) are raised to the upper portion of the flow pipe (2) together with the high pressure water (W).

Grain (S) and water (W) entered into the flow tube (2) is dropped into the washing tank (1) through the end of the bent flow tube (2). At this time, water is continuously injected through the injection nozzle 3, and thus grain S injected into the washing tank 1 together with the water W injected through the injection nozzle 3. Subsequently, it is transferred to the upper portion of the flow pipe 2 and falls into the washing tank 1.

If the grain is washed to some extent for the above process, the upper end of the flow pipe 2 is directed toward the outside of the washing tank 1 to discharge the grains S and water W inside the washing tank 1. Done. In this case, the water supply through the injection nozzle 3 is continuously performed, and the high pressure water W injected through the injection nozzle 3 discharges the grains S to the outside of the washing tank 1. It is the driving force.

However, the conventional grain washer as described above has a problem that the washing power is poor and the ability to separate the foreign matter (A) mixed in the grain (S) is inferior.

This is the washing tank (1) because it performs the washing through the process of dropping from the top of the washing tank (1) to the lower through the flow pipe (2) in the state of mixing the grain (S) with high pressure water (W) It is because the water flow formed in it is monotonous. In particular, since the grain (S) and the water (W) from the upper portion of the flow pipe (2) is dropped only to one side of the washing tank 1, the water flow formed in the washing tank (1) becomes more monotonous.

And the weight of the foreign material (A) mixed in the grain (S) is heavier than the grain (S) easily sinks to the lower portion of the washing tank (1), but the weight is similar to the grain (S) or smaller in size Outgoing is difficult to separate because the water flow formed in the washing tank 1 is monotonous.

In addition, the conventional grain washer was not provided with a water tank 5 in the washer itself, there was a hassle to prepare a separate water tank (5).

Therefore, an object of the present invention is to solve the problems of the prior art as described above, to provide a device that can clean the grain more clean and more completely remove the foreign matter mixed in the grain.

In addition, the delivery pipe 24 is provided with a pressure control valve 28 for controlling the pressure of the water injected from the nozzle 40 to be described below in multiple stages. Such a pressure control valve 28 adjusts the pressure of the water sprayed from the nozzle 40 so that the user can wash at the desired water pressure.

On the other hand, the water storage unit 11 has a washing tank 30 is fixed. The washing tank 30 is a place where the washing of the grains (S) is formed in a cylindrical shape. The cylindrical shape of the washing tank 30 as described above is for forming a rotational water flow that rotates along the inner wall of the washing tank 30 in the washing tank 30. The center of the bottom surface of the washing tank 30 is provided with a foreign matter removing unit 32 for removing the foreign matter (A) separated from the grain (S), the configuration is as follows.

That is, the foreign material removal groove 33 is formed in the center of the bottom of the washing tank (30). The foreign material removal groove 33 is covered with a mesh cap 34. The mesh cap 34 has a plurality of meshes through which the grain S to be washed does not pass, and the foreign matter A having a smaller size passes therethrough. Therefore, the mesh cap 34 is preferably to be replaced with a different size of the mesh according to the grain (S) to be washed. In addition, a discharge pipe 35 communicates with the foreign material removal groove 33, and a discharge valve 35V is installed in the discharge pipe 35.

On the inner surface of the washing tank 30, the foreign matter trapping portion 36 is formed, the position of which is about halfway between the nozzle 40 and the discharge duct 60 to be described below. Here, looking at the configuration, the strainer 37 is installed up and down the inner side of the washing tank 30 long. The strainer 37 has a mesh that does not allow the grain S to be washed. And, it is desirable to be able to exchange such a strainer 37 according to the grain (S) to be washed. On the other hand, the back of the strainer (37) is formed with a foreign matter chamber 38 in which the foreign matter (A) passing through the strainer 37 is formed, the foreign matter chamber 38 is in communication with the discharge pipe (39) It is installed. The discharge pipe 39 is provided with a discharge valve 39V.

The washing tank 30 is provided with a plurality of nozzles 40 for spraying the water delivered through the delivery pipe 24 into the washing tank 30. The nozzle 40 is installed side by side up and down on the inner wall surface of the washing tank (30). At this time, the nozzle 40 is installed to form an acute angle with the wall surface of the washing tank 30 in the direction in which the rotational flow is rotated. Such a nozzle 40 may be installed in a plurality of places in the washing tank 30, it may be installed in the inner wall of the washing tank 30 past the discharge duct 60 to be described below, as shown in FIG.

In addition, an integrated distribution pipe 41 for supplying water to the plurality of nozzles 40 is installed at the end of the delivery pipe 24, wherein the integrated distribution pipe 41 is an outer wall of the washing tank 30. Is mounted on.

On the other hand, one nozzle (40 ') of the plurality of nozzles 40 provided as described above extends long toward the center of the washing tank (30). The end of the nozzle 40 'is directed toward the tangential direction of the mesh cap 34. Such a nozzle 40 'is for adding a rotational force to the inner portion of the rotational flow, the rotational force is relatively weak.

And, the upper part of the integrated distribution pipe 41 is connected to the initial supply pipe 43 that can be introduced into the washing tank 30 in a large amount of water in a short time. The supply valve 44 is installed in the initial supply pipe 43 to control the supply of water through the initial supply pipe 43.

In addition, one side of the initial supply pipe 43 is branched to the cleaning valve 46 is provided. The hose 47 is long connected to the cleaning valve 46. The hose 47 is made of a flexible material, the user can freely adjust the direction in which the water is injected.

On the other hand, as shown in Figure 3, a plurality of guide blades 50 are installed on the bottom of the washing tank (30). The guide blade 30 is formed in a substantially arcuate shape toward the debris removing portion 32 from the inner wall surface of the washing tank 30 that the relatively heavy debris is moved by the rotating water flow from the bottom surface of the washing tank 30. It serves as a guide toward the foreign matter removing unit 32. Such a guide blade 50 is installed to be orthogonal to the extension line of the discharge duct 60 to be described below. In addition, the guide blade 50 also serves to block foreign matter (A) from being delivered to the discharge duct (60).

The discharge duct 60 is installed on one side of the lower side of the washing tank 30. The discharge duct 60 is to discharge the grain (S) once washed to the outside of the washing tank (30). Although not shown in the drawings, such discharge duct 60 extends through the housing 10 to the outside of the grain washer. Such discharge duct 60 is advantageous to discharge the grain (S) as short as possible. Since the discharge duct 60 is installed to obliquely pass through the washing tank 30, one end of the discharge duct 60 forms one guide wall 61. The discharge duct 60 is provided with a discharge valve 62.

And, Figure 4 shows another embodiment of the present invention, in which the nozzle 400 is located in three places of the washing tank (30). This is to make the rotational flow generated in the washing tank 30 more powerful. Installing the nozzle 400 in this way is to allow to adjust the strength of the rotational flow properly.

Hereinafter, it will be described to wash the grain using this embodiment having the configuration as described above.

First, water is supplied to the water storage unit 11 through the supply pipe 12. The supply of water through the supply pipe 12 is controlled by the supply valve 13 and also by the float valve 14 installed at the end of the supply pipe 12. The float valve 14 serves to prevent the water storage unit 11 from filling the water above a certain level.

When the operator operates the pump 20 while the water is stored in the water storage unit 11 as described above, the water in the water storage unit 11 is sucked through the suction pipe 23 to pump 20 Is delivered. As such, the water delivered to the pump 20 is pressurized and delivered to the integrated distribution pipe 41 through the delivery pipe 24. At this time, the pressure of the water delivered to the integrated distribution pipe 41 can be adjusted by the pressure control valve (28).

The water delivered to the integrated distribution pipe 41 as described above is delivered to the interior of the washing tank 30 through the nozzles (40, 40 ') or the initial supply pipe 43, generally grains to the washing tank (30) After being introduced into the inside, the water supply is initially introduced into the washing tank 30 in a short time through the initial supply pipe 43. At this time, the supply valve 44 is opened. When a predetermined amount of water is filled in the washing tank 30, water is supplied into the washing tank 30 through the nozzles 40 and 40 ′. In this case, the water is injected through the nozzles 40 and 40 'while maintaining the pressure of the water delivered to the integrated distribution pipe 41 by closing the supply valve 44. In this case, the pressure of the water sprayed through the nozzles 40 and 40 'may be adjusted using the pressure control valve 28.

When water is sprayed at a pressure that matches the characteristics of the grains S to be washed through the nozzles 40 and 40 'as described above, a rotating water flow is formed in the washing tank 30 as shown in FIG. 5. When rotational water flow is generated in the washing tank 30, the grain S is rotated together with the rotational water flow.

Then, the foreign matter (A) is moved to the central side or the wall surface of the washing tank (30). At this time, the foreign matter (A) having a certain weight, such as sand or soil is moved toward the center of the washing tank 30, the foreign matter (A) of light weight floats to the upper part of the wall, to the strainer (37) I get caught. Of course, the foreign matter (A) having a diameter smaller than the mesh of the strain screen 37 by the centrifugal force of the rotational flow through the strain net 37 is transmitted to the foreign matter chamber 38.

The foreign matter (A) moved toward the center of the washing tank 30 is moved to the foreign matter removing unit (32). As such, the smaller diameter of the mesh A of the foreign substance A transferred to the foreign substance removing unit 32 is moved to the foreign substance removing groove 33, and the foreign substance A having a relatively large diameter is It remains on the mesh cap 34.

The foreign material A is transferred to the foreign material removing part 32 or the foreign material trap 36 because of the centrifugal force of the rotational flow formed by the nozzle 40 and the relatively low rotational force of the rotational flow center. to be.

On the other hand, the nozzle 40 'is sprayed with water in the direction of the center of the washing tank 30 (exactly, the tangential direction of the mesh cap 34) having a relatively low rotational force of the water flow to the washing tank together with the foreign matter (A) 30) serves to join the grain (S) moved toward the center of the rotary water flow.

In addition, the guide blade 50 on the bottom of the washing tank 30 is to prevent the relatively heavy foreign material (A) is moved by the rotational water flow to the discharge duct (60). The guide blade 50 is the end portion thereof toward the foreign matter removing unit 32, guides the foreign matter (A) guided by the rotating water flow along the bottom of the washing tank 30 to the foreign matter removing unit (32). Done.

After forming the rotary water flow in the washing tank 30 to wash the grains for a predetermined time, the discharge valve 62 is opened by continuously supplying water through the nozzles 40 and 40 '. Grain (S) is discharged through. On the other hand, the guide wall 61 serves to better guide the grain (S) into the discharge duct (60). After the discharge of the grains S in this way, the supply of water through the nozzles 40 and 40 'may be stopped.

Then, the discharge valve (35V) is opened to discharge the water in the washing tank 30 to the outside through the discharge pipe (35).

On the other hand, when it is necessary to wash the grain (S) several times, the discharge valve (62V) in the discharge pipe (35) in the discharge pipe (35) in the state in which the discharge valve 62 in the discharge duct 60 is closed to discharge The water used for washing is removed through the pipe 35 and the above operation is repeated.

When the water is not injected through the nozzles 40 and 40 'as described above, backflow of the water toward the pump 20 through the nozzles 40 and 40' is prevented by the check valve 25.

When the inside of the washing tank 30 is to be cleaned, the cleaning valve 46 may be opened and cleaned while supplying water to every corner of the washing tank 30 through the hose 47.

The grain washer according to the present invention as described in detail above to form a rotary flow in the washing tank to rotate the grain with the rotary flow, it is to separate the foreign matter from the grain using the rotational force difference and centrifugal force of the rotary flow according to the position. Therefore, compared with the prior art, the ability to separate out the foreign matter relatively excellent grain washing can be expected to be more complete effect.
