DETAILED DESCRIPTION
[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] In order to solve the problem that the crushing device generates a lot of heat energy during the crushing process, the crushed material has the risk of melting, thus affecting the crushing effect, please refer to Figure 1-4, the utility model provides an embodiment: a hammer mill with water cooling function, including a grinding chamber 2 and a feed inlet 1, and also including a first water-cooling plate 8 and a second water-cooling plate 801, the first water-cooling plate 8 and the second water-cooling plate 801 are both provided with a plurality of circulating water channels 802, one end of the first water-cooling plate 8 and the second water-cooling plate 801 are respectively provided with a water inlet 803, the side of the first water-cooling plate 8 and the second water-cooling plate 801 are respectively provided with a water outlet 804, the grinding chamber 2 A rotor disk 601 and a hammer head 6 are arranged inside, and the rotor disk 601 is connected to the hammer head 6 by screws. A first fan 301 is arranged on one side of the grinding chamber 2, and a second fan 302 is arranged on the other side of the grinding chamber 2. A discharge port 3 is arranged at one end of the first fan 301, a feed bin 101 is arranged below the feed port 1, and a feed baffle 102 is arranged inside the feed bin 101. A cover opening reducer 4 is arranged on the side of the grinding chamber 2, and a motor 5 is arranged on one side of the cover opening reducer 4.
[0023] A screen 7 is arranged below the rotor disk 601. The screen 7 is an arc-shaped steel plate structure with a plurality of through holes on the surface. The screen 7 is connected to the grinding chamber 2 by screws. Material particles of appropriate size in the grinding chamber 2 fall from the through holes of the screen 7 into the storage chamber below. The second fan 302 discharges the material particles. When the through holes of the screen 7 are blocked, the first fan 301 can be turned on to blow away the blocked material, thereby further improving the efficiency of material crushing.
[0024] The first water-cooling plate 8 and the second water-cooling plate 801 are both arc-shaped structures. A cover plate 203 is provided on the outer convex surface of the second water-cooling plate 801. A limit block 202 is provided at one end of the cover plate 203. The other end of the cover plate 203 is connected to the grinding chamber 2 through a connecting piece 201 in an openable and closable manner. When the internal temperature of the grinding chamber 2 is too high, cold water is injected from the water inlet 803 and then recovered from the water outlet 804. The cold water takes away the heat inside the water-cooling plate, thereby lowering the temperature inside the grinding chamber 2 and further reducing the possibility of the material being melted. At the same time, the water-cooling plate filled with cold water has the ability to absorb noise, further suppressing the noise generated by the collision between the material in the grinding chamber 2 and the hammer head 6.
[0025] The feed baffle 102 is connected to the feed bin 101 through an axis, and the axis is installed on the upper half of the feed baffle 102. The feed baffle 102 is divided into two rectangular steel plates of different sizes by the axis. The limit block 202 presses against the side of the small rectangular steel plate of the feed baffle 102, so that the feed baffle 102 can only be opened to the inside of the grinding chamber 2, thereby forming a one-way door, which further solves the problem of material splashing in the grinding chamber 2.
[0026] The cover plate 203 is connected to the cover opening reducer 4 through a connecting rod 401. The cover opening reducer 4 can automatically open the cover plate 203 by controlling the connecting rod 401. At the same time, the cover opening reducer 4 has the function of quickly reducing the rotation speed of the hammer head 6, thereby improving the safety when replacing the hammer head 6 and the screen 7, and further avoiding the possibility of safety hazards caused by the staff opening the cover plate 203 at a high rotation speed.
[0027] Working principle: the material passes through the feed bin 101 and enters the interior of the grinding chamber 2. The hammer 6 inside the grinding chamber 2 is connected to the rotor disk 601 by screws. When the rotor disk 601 is driven to rotate by the external motor 5, the hammer 6 rotates at the same time. The rotating hammer 6 breaks and grinds the material, and the material particles of appropriate size fall from the through holes of the screen 7 into the storage chamber below. The second fan 302 discharges the material particles. As time goes by, the internal temperature of the grinding chamber 2 rises rapidly. At this time, cold water is injected from the water inlet 803 and then recovered from the water outlet 804. The cold water takes away the heat inside the water cooling plate, thereby reducing the temperature inside the grinding chamber 2. When it is necessary to stop the operation, turn on the cover reducer 4, the cover reducer 4 quickly reduces the rotation speed of the hammer 6, and automatically opens the cover 203.
