Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pulverizing means of a pulverizer for pulverizing foods, organic substances, minerals, etc. into fine particles (for example, on the order of microns). This invention relates to a crushing means of a fine crusher which is made into a cassette and is separable from the drive means of the fine crusher.

[Prior Art] Conventionally, the crushing means in this type of pulverizer has been configured to include a rotary mortar and a fixed mortar that face each other. The fixed mortars located on the upper part of the rotary shaft are respectively fixed to the cover side that covers the open end surface of the housing of the pulverizer. Therefore, in this prior art, when cleaning the inside of the pulverizer, etc., when opening and closing the lid, a slight crease tends to form between the upper and lower dials, and for this reason, pulverization is preferable. In order to do this, it is necessary to repeat 1 to 2 each time and make fine adjustments between the two discs.This adjustment work is troublesome, and it is extremely difficult to maintain the sliding surface at a constant level of accuracy for a long period of time. There was a certain drawback. In addition, if the grinding effect becomes weak due to wear of the rotary and fixed mortars, remove the lid that covers the open end of the housing, replace the two dies on the north side, and then carefully clean the mating surfaces of the two dies on the upper and lower sides. The desired fine pulverization cannot be achieved without readjusting the parts, resulting in extremely low work efficiency, and also the trouble of replacing and adjusting them.

[Problems to be Solved by the Invention] The present invention has been made in view of the following two conventional circumstances, and therefore, its object is to provide a rotary mill comprising a fixed mill and a rotary mill equipped with a grinding surface. To provide a pulverizing means of a fine pulverizer, which enables extremely efficient pulverizing work by using an easily replaceable cassette as the pulverizing means and by making it possible to easily and quickly remove the worn pulverizing means. 3. Another object of the present invention is that it is possible to set the clearance between the rotary mill and the fixed F to a desired value by setting a cellar in advance outside the pulverizer, thereby controlling the properties of the material to be pulverized. The purpose is to provide a means for easily pulverizing the pulverizer by setting the optimum clearance between the two according to the pulverizer.

Another object of the present invention is to provide a pulverizing means for a fine pulverizer that can be easily assembled, disassembled, and disassembled for cleaning.

[Means for Solving the Problems] The pulverizing means of the pulverizer according to the present invention includes a rotor whose end face is formed as a grinding surface, and which is rotated by the drive means of the pulverizer, and which is disposed opposite to the rotor.

Further, inside the housing 53 of the pulverizer 51, there is provided a shaft cylinder 68 in which bearings 71, 72 for the rotary shaft 54 are housed in the upper and closed portions of the housing 53, and the rotary shaft 54 is recessed. A cup link 69 connected to the rotating shaft 54 and a clutch 70 fixed to the cup link 70 and having key grooves 74 and 74 on the upper surface thereof are disposed above the shaft cylinder 68. The keys 10.10 (see FIG. 3) provided at the bottom of the rotor 3 are engaged in the key grooves 74.74 of the lever (see FIG. 10), and the crushing means (cassette) is connected to the clutch 70''. 1 is placed, the rotation of the rotating shaft 54 is transmitted to the rotor 3. Also, this housing 5
A frame body 7 is provided on the inside edge of the frame 7, which presses against the notches 34, 34 of the housing 3o of the crushing means 1 placed on the crutch 7o and prevents the crushing means 1 from escaping to one side.
3 are rotatably pivoted (Figures 11 and 12).

Furthermore, a wooden gutter 75 (see Fig. 6) is provided on the outside of the crank punch 70 for discharging the water discharged from the water drain hole 3B provided in the rotor 3 to the outside. .

A charging port 1TJ63A is formed approximately at the center of the lid 63, and a charging port r+67A of the hopper 67 is located directly in front of the charging port n63A. The hopper 67 can be freely raised and lowered together with the lid 63 by the jack 92. Furthermore, this lid body 63 is provided with fine adjustment means 8 (2) that can finely adjust the clearance between the rotor 3 and the fixed port from the outside.
(See Figure 11). The fine adjustment means 80
The tip of the cassette is in contact with the frame 73 that is engaged with the notches 34 and 34 of the housing sink 30, which constitutes the crushing means (cassette) (2). This fine adjustment means 80 is a conversion 81
A screw punch 82 for fine adjustment is screwed into a female threaded portion 83 fixed to the lid 63, and a contact portion 84 that comes into contact with the frame 73 is provided at the tip of the screw punch 82. The female threaded portion 83 has a set screw 85 that locks the adjusting screw 82 in a desired set state.

Therefore, by turning the converter 81 and pressing the frame 73 that is in contact with the contact portion 84, it is possible to push the housing sink 30 down toward the rotor 3 side.

Reference numeral 89 denotes a fork attached to the tip of the base plate 88 fixed to the lid 63, and four parts of the fork 89 include:
A screw punch 90 for fixing the lid body 63 rotatably attached to the upper edge of the cover 61 is inserted by half a turn, and a knob 93 screwed into this screw punch 90 is tightened to remove the lid body 63.
or is fixed to and covered by the cover 61. In this state, the rubber gasket 37 attached to the link 20 of the crushing means 1 comes into contact with the lower end surface of the lid 63 and is pressed. For this reason, the keyway 74 of the clutch 70.
The engagement between 74 and the key 10.10 of the rotor 3 becomes more reliable.

Now, before actually setting the crushing means 1 in the pulverizer 51, the fixed mill 4 is pushed down toward the rotor 3 by the pusher d29B constituting the pushing means 26, and the rotor 3 and the fixed mill are separated. Adjust the clearance in advance. Grinding means (cassette) 1 set in the current state
is set in the required part of the pulverizer 51, and when the material to be pulverized (not shown) is inputted from the hopper input port 67A of the pulverizer 51, it is transferred to the housing sink 5 through the input port [i3A of the lid 63].
The material to be crushed is dropped onto the rotor 3 which is rotating within the rotor 3. Then, the object to be crushed moves on the diamond electrodeposited layer, which is the grinding surface 3A formed on the upper surface of the rotor 3, due to centrifugal force, and is finally finely crushed between it and the fixed mill 4. It scatters outward, hits the inner wall surface of the cover 61, and is discharged from the discharge port 60. At this time, the waste water is discharged from the drain hole 76 to the outside through the drain gutter 75. While repeating such operations, if the dressing of the fixed mortar 4 progresses, loosen the IL screw 85, rotate the fine adjustment means 80 by rotation 81, and press the frame 73 downward. For example, since the housing 30 of the crushing means 1 is pushed down while resisting the compression coil spring 28, the clearance between the rotor 3 and the fixed die 4 can be easily corrected for enlargement.

If the limit of clearance correction is reached, the crushing means can be replaced as follows.

That is, loosen the nof 93 provided on the tip side of the lid body 63 and screw it down to 9.
0 from the fork 89, and raise the lid 63 and hopper 67 to the upper position A using the lid lifting jack 92. After this operation, the entire lid 63 is horizontally rotated to form an open end surface above the house sink 53 of the pulverizer 51, and the frame 73 is further pushed upward to form the pulverizing means (cassette). Since it can be removed more easily than the clutch 70, it can be replaced with a new crushing means. Then, when the new crushing means 1 is installed and set in the clutch 70, reversely,
The lid body 63 can be rotated and closed to perform the crushing operation.

As a modification of the ground surface of the rotor constituting the present invention, as shown in FIG. 13, spiral grooves IG:IC may be provided on the ground surface 103A, or radial grooves may be provided. Of course.

[Effects of the Invention] The present invention is constructed and operates as described below, and has the following advantages.

(1) Due to the increased clearance between the rotor equipped with a grinding surface and the fixed mill, even when the limit is reached, the crushing method can be easily and
Since it can be replaced quickly, it is possible to increase the work efficiency of fine pulverization. (2) Since the rotor is fixed perpendicular to the axial direction of the short shirts 1 to 1, there is no possibility of surface runout of the rotor. This makes it possible to keep the particle size of the pulverized material constant even when the pulverization process lasts for a long time.

(3) Since the crushing means can be easily assembled and disassembled, it can be disassembled and cleaned as needed.
