Description

[Technical field]

[0001] The present invention relates to a crushing device, and more particularly to a crushing device for crushing solid matter contained in a liquid to prevent clogging. [Background technology]

[0002] In the cultivation of agricultural crops and flowers, fertilizer is sprayed together with water onto fields, greenhouses, etc. At this time, for reasons such as spraying efficiency, the fertilizer is mixed with water to be fluidized and then sprayed from a sprinkler. Here, the fertilizer is dissolved in water beforehand, or crushed into pieces smaller than the holes in the sprinkler nozzle (shower head). If this is not done, clogging will occur on the sprinkler side, which will not only reduce the efficiency of watering and fertilization, but may also cause the sprinkler to break down.

[0003] Therefore, after dissolving the fertilizer in water, it is necessary to crush it to a level that does not cause problems when watering.For example, a liquid fertilizer raw material manufacturing device has been proposed that includes a cylindrical body, an inverted truncated cone-shaped lower part that continues to the cylindrical body, a bottom screen that forms the bottom surface of the inverted truncated cone-shaped lower part, and a horizontal rotary cutter that is provided directly above the screen (see Patent Document 1).

[0004] The device referred to in Patent Document 1 has improved the crushing efficiency. However, since the device is used to crush food waste with the assumption of producing fertilizer, the crushing degree is coarse. Therefore, when considering watering and liquid fertilizer application during cultivation of agricultural crops and flowers, the device in Patent Document 1 cannot fully cope with the above.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] When organic fertilizer is mixed and dissolved in water to prepare liquid fertilizer, the water-soluble components dissolve quickly, but the solid components of the organic fertilizer, such as rotten tree branches and leaves, and food waste, do not dissolve and remain in the liquid. Even in the case of chemical fertilizer, the components of the chemical fertilizer may remain undissolved depending on the water temperature. Recently, when cultivating crops and flowers, liquid fertilizer is used for fertilization in addition to watering. In this case, a sprinkler for watering is also used for fertilizing the liquid fertilizer. In this case, if the undissolved solid components of the organic fertilizer and chemical fertilizer are directly circulated through an irrigation hose, clogging will occur at the sprinkler nozzle (shower head). Of course, it is possible to place a mesh or filter in the flow path to filter out the undissolved solid components.

[0021] However, when liquid fertilizer passes through the mesh and filter, pressure is required to deliver the liquid. Therefore, a separate pump for pressure delivery, a tank for storage, and other equipment, as well as piping that can withstand the pressure, are required. In the crushing device of the embodiment, the prepared liquid fertilizer is crushed to a size that will not cause clogging before being circulated through the irrigation hose, thereby avoiding clogging in the sprinkler and eliminating the need to install new equipment such as pumps and piping. The crushing device of the embodiment also reduces the installation burden on existing sprinkler equipment, making it easier to introduce.

[0022] The overall configuration of the pulverizing device 1 of the embodiment will be described with reference to the side view of Fig. 1 and the exploded perspective view of Fig. 2. The pulverizing device 1 is a device that treats the liquid to be treated, which is the liquid fertilizer in which the above-mentioned organic fertilizer is dissolved and the liquid fertilizer in which the chemical fertilizer is dissolved, and pulverizes the solids contained in the liquid to a size that does not cause clogging. Before passing through the pulverizing device 1, the liquid to be treated contains solids of the organic fertilizer and the chemical fertilizer that could not be dissolved.

[0023] The apparatus comprises an inner container section 10 into which the liquid to be treated is poured, and an outer container section 50 which houses the inner container section 10, an outer frame section 16 is disposed above the outer container section 50, and a grinding section 30 is provided below the inner container section 10 (see Figure 2).

[0024] The inner container part 10 has an injection opening 11 through which the liquid to be treated is injected. In this embodiment, a cylindrical fitting part 17 is connected to the injection opening 11 of the inner container part 10. An upper flange part 18 is provided around the periphery (outer surface) of this fitting part 17, and a flange gear part 19 is formed on the circumferential part of the upper flange part 18. That is, the inner container part 10 in this embodiment is rotatable inside the outer container part 50.

[0025] In the crushing device 1, the liquid to be treated is poured into the inner container 10 through the pouring opening 11. The inner container 10 has a cylindrical shape having a bottom 12 and a side surface 13, and the liquid to be treated is stored in a storage portion 10i (see Figs. 4 and 6) surrounded by the side surface 13 of the inner container 10. The bottom 12 of the inner container 10 is provided with a bottom flange portion 46.

[0026] The outer container part 50 covers the bottom part 12 and the side part 13 of the inner container part 10 and houses the crushing part 30. In the crushing device 1 of this embodiment, a drain pipe 56 is connected to the outer container bottom part 52 below the outer container body part 53 of the outer container part 50, and the liquid to be treated that has been crushed is discharged from the drain pipe 56 to the outside of the crushing device 1. In addition, a vibration part 60 is provided on the outer container bottom part 52 of the outer container body part 53. A motor 55 and a pinion 59 are provided near the outer container opening part 51 of the outer container body part 53. The vibration part 60 and the motor 55 will be described later.

[0027] As can be seen from the exploded perspective view of FIG. 3, the crushing section 30 is composed of a combination of multiple ring members. The crushing section 30 is made up of three ring members, namely, an upper ring member 33, a middle ring member 32, and a bottom ring member 31, stacked from the top. These three ring members are stacked and rotated to crush solids by a grinding action that mimics that of a mortar. In the illustrated embodiment, the crushing section 30 is further combined with an induction ring member 20. An inclined surface portion 21 is formed on the induction ring member 20, and the liquid to be treated is guided through the inclined surface portion 21 to the central opening portion of the three ring members, namely, the upper ring member 33, the middle ring member 32, and the bottom ring member 31.

[0028] The bottom ring member 31 is connected to the outer container bottom 52 of the outer container part 50. The upper ring member 33 is disposed above the bottom ring member 31 and is connected to the bottom 12 of the inner container part 10. The middle ring member 32 is disposed between the upper ring member 33 and the bottom ring member 31 and slides relative to the upper ring member 33 and the bottom ring member 31. Thus, the bottom ring member 31 is a fixed ring member fixed to the outer container part 50 of the crushing device 1, and the upper ring member 33 is a rotating ring member connected to the bottom 12 of the inner container part 10 via the guide ring member 20. Furthermore, the middle ring member 32 is rotatable following the rotation of the upper ring member 33.

[0029] In addition, the middle ring member 32 in the illustrated embodiment has a roller bearing configuration (see FIG. 3). Specifically, a plurality of cylindrical (alternatively spherical (steel ball) or truncated cone) rolling elements 25 (rollers for bearings, bearing rollers) are provided, and the rolling elements 25 are accommodated in accommodation holes 26 formed radially in the middle ring member 32. As shown in the figure, a groove 38 for the rolling elements 25 to roll is formed in the upper surface of the bottom ring member 31, and the movement range of the rolling elements 25 is restricted by the groove 38 so that the middle ring member 32 does not shift from the bottom ring member 31.

[0030] When the inner container part 10 rotates, the upper ring member 33 connected to the induction ring member 20 also rotates. Here, by interposing the middle ring member 32 between the upper ring member 33 and the bottom ring member 31, the sliding resistance when the upper ring member 33 rotates relative to the bottom ring member 31 is reduced. As a result, the driving force required to rotate the inner container part 10 (upper ring member 33) is reduced, making it possible to rotate the upper ring member 33.

[0031] The crushing mechanism in the crushing section 30 will be described with reference to the partially enlarged cross-sectional views of Figs. 4 and 5. Fig. 4 shows the bottom 12 of the inner container 10 in the crushing device 1 of the embodiment, and the crushing section 30 provided on the bottom 12. In the figure, a protrusion 22 protruding toward the storage section 10i is provided on the inner surface of the side surface 13 near the bottom 12 of the inner container 10, and the guide ring member 20 is placed on the protrusion 22 and combined with the inner container 10. Then, the upper ring member 33 is connected to the guide ring member 20. When connecting the upper ring member 33 and the guide ring member 20, a suitable structure such as a meshing of a recess and a protrusion is adopted (not shown). In this way, the rotation of the inner container 10 is reliably reflected in the rotation of the upper ring member 33. In the figure, the rolling body 25 of the middle ring member 32 is not shown.

[0032] When the liquid to be treated is injected into the inner container 10 and stored in the storage section 10i, the solid content contained in the liquid to be treated falls through the inclined surface 21 of the guide ring member 20 to the inside (left side of the drawing) of the upper ring member 33, the middle ring member 32, and the bottom ring member 31 of the annular crushing section 30. In this state, the upper ring member 33 starts to rotate. In the crushing device 1 of the embodiment, the pinion 59 rotates as the motor 55 installed near the outer container opening 51 of the outer container body 53 is driven, and the pinion 59 and the flange gear section 19 also rotate in mesh (see Figs. 1 and 2). The flange gear section 19 is provided in the fitting section 17, and the fitting section 17 is connected to the inner container 10. The rotational drive of the motor 55 is transmitted to the pinion 59 and the flange gear section 19, and the inner container 10 rotates. As a result, the upper ring member 33 rotates when the motor 55 is driven, and at the same time, the middle ring member 32 also rotates in accordance with the rotation of the upper ring member 33 .

[0033] In the drawing, a bottom flange portion 46 is provided on the outer periphery of the lower end of the side portion 13, which is the bottom portion 12 of the inner container portion 10. The bottom flange portion 46 is provided with a filtration portion 45. The state of filtration will be described in detail with reference to FIG.

[0034] 5 is a partially enlarged cross-sectional view of three ring members, the upper ring member 33, the middle ring member 32, and the bottom ring member 31, which are the main parts of the crushing section 30 (see FIG. 3). As can be seen from FIG. 5 and FIG. 4, the side of the storage section 10i injected into the inner container section 10 becomes the inlet section 48 of the crushing section 30, and the opposite side across the crushing section 30 becomes the outlet section 49 of the crushing section 30. The liquid to be treated, which contains solids, flows into the crushing section 30 from the inlet section 48 and flows out from the outlet section 49.

[0035] At this time, the rotation of the inner container 10 accompanying the rotation drive of the motor 55 rotates the upper ring member 33, causing the middle ring member 32 to slide against the upper ring member 33 and the bottom ring member 31. Then, solids contained in the liquid to be treated penetrate into the gap 41 (upper gap) between the upper ring member 33 and the middle ring member 32 and the gap 42 (lower gap) between the bottom ring member 31 and the middle ring member 32. Then, the solids contained in the liquid to be treated that penetrate through the gap 41 and the gap 42 are crushed by the pressure of the upper ring member 33, the middle ring member 32, and the bottom ring member 31.

[0036] Moreover, on the inlet section 48 side of the crushing section 30, the middle ring member 32 has a middle ring inclined section 36 that becomes thinner toward the inside of the ring (the inlet section 48 side shown in the figure). The middle ring inclined section 36 has a horizontally tapered cross section likewise on the top and bottom, so that solids contained in the treated liquid can easily penetrate from the inlet section 48 side into the gap 41 (upper gap) and the gap 42 (lower gap).

[0037] Therefore, the distance between the upper ring member 33 and the middle ring member 32 at the middle ring inclined portion 36 of the middle ring member 32 and the inlet distance 4i between the bottom ring member 31 and the middle ring member 32 are longer than the gap 41 (upper gap) and the gap 42 (lower gap). The internal distance 4o between the gap 41 (upper gap) and the gap 42 (lower gap) at the center of the crushing section 30 is narrower than the inlet distance 4i of the middle ring inclined portion 36. The sliding of the upper ring member 33, the middle ring member 32, and the bottom ring member 31 in the crushing section 30 causes an action similar to that of a mill, and the solid content is ground (crushed) by the ring members rubbing against each other. Finally, the solid content contained in the treated liquid is ground by passing through the gap 41 (upper gap) and the gap 42 (lower gap) and is discharged from the outlet portion 49 side of the crushing section 30.

[0038] According to the crushing section 30 of the crushing device 1 of the embodiment, the solid content contained in the liquid to be treated is crushed to a particle size of 0.2 mm or less as it passes from the inlet 48 side of the crushing section 30 through the gap 41 (upper gap) and the gap 42 (lower gap) to reach the outlet 49 side. Specifically, the inlet clearance 4i is designed to be 1 mm, and the inner clearance 4o is designed to be 0.1 mm. The upper ring member 33, the middle ring member 32, and the bottom ring member 31 are made of a material such as stainless steel, taking into consideration the corrosion resistance of the liquid fertilizer. In addition, the cross-sectional area of ​​the 2 The solid content is 0.1 mm 2 To crush the material to a cross-sectional area of ​​25.46 N / m 2 A load of 0.549 or more is required, and the upper ring member 33, the middle ring member 32 and the bottom ring member 31 are finished to a surface roughness such that the mutual friction coefficient is 0.549 or more.

[0039] The partially enlarged cross-sectional view of Fig. 6 shows the vicinity of the bottom flange 46 of the bottom 12 of the inner container 10. The solids contained in the liquid to be treated are pulverized through the pulverizing section 30 of the pulverizing device 1. However, there may be cases where the pulverization is uneven or incomplete. Therefore, a section is provided to prevent the outflow of solids with large particle sizes. As shown in Fig. 6 and Fig. 4 above, the bottom flange 46 is provided with a filtration section 45. The filtration section 45 is provided with a filter such as a resin or metal mesh or nonwoven fabric, and the unevenly or incompletely pulverized solids are filtered (captured) to prevent the outflow of the solids.

[0040] As shown in Fig. 6, the liquid to be treated discharged from the outlet 49 of the crushing section 30 flows out of the inner container section 10 through the bottom 12 of the inner container section 10 and flows into the outer container bottom 52 below the outer container body 53 of the outer container section 50. The liquid to be treated that has accumulated in the outer container bottom 52 overflows from the filtration section 45 of the bottom flange section 46. At this time, solids that have been unevenly or incompletely crushed can be filtered in the filtration section 45. The liquid to be treated after filtration is then discharged outside the crushing device 1 from a drain pipe 56 installed below the outer container body 53 of the outer container section 50.

[0041] The dashed arrows in Fig. 6 indicate the route through which the liquid to be treated passes. The surface of the filtration section 45 that filters the liquid to be treated faces downward, preventing leakage of solids, and the filtered liquid to be treated is discharged from the drain pipe 56.

[0042] 1 and 2, the crushing device 1 of the embodiment is provided with a vibration unit 60 at the outer container bottom 52 of the outer container part 50, i.e., directly below the crushing part 30. The vibration unit 60 may be, for example, a vibration motor having a mechanism of a motor and a cam (eccentric weight), or an ultrasonic vibrator. In the case of a vibration motor, the vibration motor vibrates the liquid to be treated that has flowed into the crushing part 30 located directly above the outer container bottom 52, thereby suppressing precipitation of solids contained in the liquid to be treated. In the case of an ultrasonic vibrator, the shock waves directly crush the solid particles, thereby assisting crushing in the crushing part 30.

[0043] The schematic cross-sectional view of Fig. 7 discloses another embodiment of the crushing section 30 of the crushing device 1 of the embodiment. In the drawing, the middle ring member 32 is omitted in the crushing section 30, and the upper ring member 33 directly abuts and slides against the bottom ring member 31. In the example of Fig. 7, when the upper ring member 33 rotates and slides against the bottom ring member 31, solids contained in the treated liquid penetrate into the gap 40 between the upper ring member 33 and the bottom ring member 31 and are crushed by the pressure between the upper ring member 33 and the bottom ring member 31.

[0044] In addition, as shown in the figure, the upper ring member 33 has an upper ring inclined portion 34 that becomes thinner toward the inside of the ring, and the bottom ring member 31 has a bottom ring inclined portion 35 that becomes thinner toward the inside of the ring. Thus, the inlet separation amount 4i on the inlet portion 48 side is wider than the internal separation amount 4o on the outlet portion 49 side. Of course, the structure in which the upper ring inclined portion 34 and the bottom ring inclined portion 35 are made thin can also be applied to the crushing portion 30 disclosed in Figures 3 to 5.

[0045] As explained above, the solids that cause clogging are crushed by the pressure of the upper ring member 33, the middle ring member 32, and the bottom ring member 31 (see Figs. 3, 4, and 5). Alternatively, they are crushed by the pressure of the upper ring member 33 and the bottom ring member 31 (see Fig. 7). Here, in order to efficiently crush and pulverize the solids, it is sufficient to press them toward the bottom ring member 31 to an extent that does not interfere with the rotation between the ring members. When a load is applied from above to each ring member, the gap between the ring members is less likely to widen, and the solids are more likely to be crushed at all times.

[0046] Therefore, a weight member is provided on the upper ring member 33. In the embodiment disclosed in the partially enlarged cross-sectional view of FIG. 8, the weight is increased by increasing the thickness of the upper ring member 33s, and the upper ring member 33s itself becomes a weight member. The upper ring member 33s itself acts as a weight and can press the middle ring member 32 and the bottom ring member 31. In the embodiment disclosed in the partially enlarged cross-sectional view of FIG. 9, a weight member 37 (weight ring member) is provided directly above the upper ring member 33. The weight member 37 is an annular member made of the same material as the upper ring member 33, etc. The load of the weight member 37 is applied to the upper ring member 33, the middle ring member 32, and the bottom ring member 31. It is possible to increase the thickness of the upper ring member or provide a separate weight member (weight ring member) for a form in which the middle ring member 32 is omitted as in the cross-sectional schematic view of FIG. 7 (not shown).

[0047] In addition, as shown in the partially enlarged cross-sectional view of the crushing portion in Fig. 10, crushing grooves are formed in various places of the ring members. In the embodiment disclosed in Fig. 10, an upper ring crushing groove 47 is formed in the upper ring member 33. In the middle ring member 32, a middle ring upper crushing groove 43 is formed in the middle ring member 32 on the side facing the upper ring member 33, and a middle ring lower crushing groove 44 is formed in the middle ring member 32 on the side facing the lower ring member 31. Each crushing groove (upper ring crushing groove 47, middle ring upper crushing groove 43, middle ring lower crushing groove 44) is a gently tapered groove whose depth becomes shallower from the inlet portion 48 side to the outlet portion 49 side.

[0048] The crushing grooves (upper ring crushing groove 47, middle ring upper crushing groove 43, middle ring lower crushing groove 44) play the role of the grooves of a so-called millstone in the ring member. The solid content flowing in from the inlet 48 side is likely to enter the deep side of the crushing grooves (upper ring crushing groove 47, middle ring upper crushing groove 43, middle ring lower crushing groove 44). Therefore, the solid content is gradually crushed while proceeding to the outlet 49 side in the crushing grooves (upper ring crushing groove 47, middle ring upper crushing groove 43, middle ring lower crushing groove 44 shown in the figure) with the rotation of the upper ring member 33, the middle ring member 32, and the bottom ring member 31. The crushing grooves shown in the figure may be configured in combination with the above-mentioned weight member. In addition, in the example of FIG. 7, crushing grooves may be formed in either or both of the upper ring member 33 and the bottom ring member 31.

[0049] As explained above, in the embodiment of the pulverizing device, the solids contained in the liquid to be treated are crushed and pulverized by the friction of the upper ring member, the middle ring member, and the bottom ring member in the pulverizing section. Therefore, clogging of the sprinkler nozzle (shower head) of the sprinkler is suppressed. Furthermore, the vibration section assists the pulverization in the pulverizing section. In addition, even if there are residual crushed parts in the pulverizing section, the passage of solids that are not uniformly or incompletely crushed is suppressed through the filtration section. Furthermore, by providing the weight member, the load applied to each ring member is increased, making the solids more likely to be crushed. In addition, by forming a crushing groove section in each ring section, the function of a millstone is added, making it easier to grind the solids. [Explanation of symbols]
