Description

Technical Field

[0001] The invention relates to the technical field of gypsum board production equipment, and in particular to a gypsum drying and dispersing device capable of reducing material blockage. Background Art

[0002] In the production process of gypsum board, calcining clinker is a key process. The calcination quality of clinker will directly affect the quality of the finished gypsum board. Calcination is divided into pre-calcination and calcination. In order to ensure the quality of calcination, it is necessary to crush and dry the gypsum material during pre-calcination in the calcination line to remove the free water and part of the internal water of the gypsum material, and then transport the crushed and dried gypsum powder to the boiling furnace for calcination.

[0003] In the prior art, the pre-calcination equipment mainly consists of a disperser and a hot air blower. The disperser beats the gypsum material into powder, and then introduces hot air to dry and dehydrate the powdered gypsum powder. However, due to its own high humidity, the gypsum material sticks to the wall and hangs on the wall when dispersed. Such long-term accumulation will cause the space inside the disperser to become smaller and smaller, resulting in tripping and stopping, so that the pre-calcined powder inside is over-calcined or low-temperature calcined due to accumulation, thereby reducing the quality of the powder. Summary of the invention

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] The present invention provides a gypsum drying and dispersing device for reducing material blockage, comprising a body 1 with a funnel-shaped material inlet 11 on the top, a cavity inside, and a cylindrical material outlet 12 at the bottom;

[0032] A crushing device 2 is provided in the internal cavity of the machine body 1 and is used to crush the gypsum material into particles of a certain size;

[0033] A driving device 3 is provided outside the machine body 1, connected to the crushing device 2, and provides power for the crushing device 2;

[0034] A vibration device 4 connected to the components of the pulverizing device 2 and the side wall of the discharge port 12 to prevent the gypsum material from adhering to the inside of the machine body 1 and the inner wall of the discharge port 12;

[0035] The drying device 5 is located below the machine body 1 and is connected to the discharge port 12 and is used for drying and dehydrating the crushed gypsum material.

[0036] In the present invention, the block-shaped uncalcined gypsum material enters the inner cavity of the machine body 1 from the feed port 11 of the machine body 1, the driving device 3 drives the crushing device 2 to operate, breaks up the gypsum material, and discharges it from the discharge port 12 of the machine body 1, and falls into the drying device, the drying device dries the powdered gypsum material and discharges it into the subsequent process, wherein the vibration device 4 outputs vibration at the relevant components of the crushing device 2 and the discharge port 12 of the machine body 1, thereby shaking off the gypsum material adhering to the crushing device 2 and the inner wall of the discharge port 12, and at the same time preventing the gypsum material from hanging on the inner wall of the crushing device 2 and the discharge port 12, so as to prevent the accumulation of materials from affecting the operation of the machine body 1.

[0037] Furthermore, the pulverizing device 2 includes a rotor 21, a hammer head 22, an impact plate 23 and an isolation plate 24;

[0038] The rotor 21 is rotatably connected to the internal cavity of the body 1, and the side shaft extends to the outside of the body 1 and is connected to the driving device 3. The hammer head 22 is provided with a plurality of hammers fixedly connected to the outside of the rotating surface of the rotor 21 and distributed in a circular array around the rotation center of the rotor 21. The impact plate 23 is provided below the feed port 11 and is located on one side of the rotor 21 and fixed on the inner wall of the body 1. The isolation plate 24 is provided with sieve holes connecting the upper and lower surfaces on its surface and is provided above the discharge port 12.

[0039] Among them, below the feed inlet 11 is one side of the rotor 21, and the tangential rotation direction of the rotor 21 in the vertical direction of the side is vertically downward.

[0040] In the present invention, the gypsum material is poured into the internal cavity of the machine body 1 from the feed port 11 and falls downward due to its own gravity. The rotor 21 in the internal cavity of the machine body 1 rotates under the drive of the No. 1 motor 31 and drives the hammer head 22 fixed on its surface to make uniform circular motion around its rotation center. The hammer head 22 hits the gypsum material and throws it onto the counterattack plate 23 on one side, so that the gypsum material is broken into powder. The powdered gypsum material moves to the surface of the isolation plate 24 driven by the hammer head 22 and its own gravity, and passes through the sieve holes on the surface of the isolation plate 24. It falls into the discharge port 12, and then falls out of the machine body 1 to enter the next process, wherein the hammer heads 22 are arranged in a circular array around the rotation center of the rotor 21, so that the overall mass distribution of the rotor 21 can be uniform and the rotation is more stable. On the other hand, the rotation direction of the rotor 21 below the feed port 11 is the same as the falling direction of the gypsum material, so that the hammer heads 22 can better hit the falling gypsum material onto the impact plate 23, and prevent the gypsum material from falling into the gap between the other side of the rotor 21 relative to the impact plate 23 and the inner cavity of the machine body 1, causing jamming or directly falling out from the discharge port 12 below.

[0041] Furthermore, both sides of the rotor 21 extend outward to form a connecting side plate 211, and the hammer head 22 is roller-shaped, with both ends rotatably connected to the side plates 211 at both ends. The surface of the hammer head 22 is provided with densely distributed round head-shaped protrusions 221, and the outer movement trajectory of the hammer head 22 is 1-2 cm away from the inner surface of the isolation plate 24.

[0042] When the gypsum material is shattered by being hit by the rotating hammer 22 onto the impact plate 23, if there are still large pieces of gypsum material that fall onto the surface of the isolation plate 24 and cannot pass through the sieve holes, the rotating hammer 22 will roll over the surface of the gypsum material when passing over the upper surface of the isolation plate 24. The hammer 22 rolls around the connection between itself and the side plate 211, and the round-headed protrusions 221 on its surface squeeze the gypsum material together with the upper surface of the isolation plate 24 to further crush it, thereby achieving a better effect of breaking up the gypsum material. The large pieces of gypsum material that cannot be crushed will be moved to the top of the rotor 21 again under the drive of the hammer 22, and will be thrown onto the surface of the impact plate 23 again. The 1-2 cm gap between the hammer 22 and the isolation plate 24 can avoid frictional heat generation between the hammer 22 and the surface of the isolation plate 24, and at the same time provide a margin space for the vibration of the isolation plate 24.

[0043] Furthermore, the driving device 3 includes a No. 1 motor 31 fixed to the outside of the body 1, a No. 1 pulley 32 fixedly connected to the output shaft of the No. 1 motor 31, and a No. 2 pulley 33 fixedly connected to the middle rotating shaft of the rotor 21 and located at one end outside the body 1, and a belt transmission is provided between the No. 1 pulley 32 and the No. 2 pulley 33.

[0044] In the present invention, the first motor 31 drives the first pulley 32 to rotate, and then the first pulley 32 transmits the motion to the second pulley 33 through the belt transmission, and the second pulley 33 drives the rotor 21 to rotate together, thereby achieving the dispersion of the gypsum material inside the machine body 1.

[0045] Furthermore, the vibration device 4 includes a vibrator 41 fixed to both sides of the discharge port 12, a No. 1 spring 42 arranged between the bottom edge of the isolation plate 24 and the bottom inner wall of the body 1, a rubber interlayer 44 arranged between the end of the isolation plate 24 and the bottom end of the counter-attack plate 23, and a No. 2 spring 43 arranged between the back of the counter-attack plate 23 and the inner wall of the body 1;

[0046] The top of the discharge port 12 is fixed to the lower surface of the isolation plate 24, the side of the discharge port 12 is not connected to the machine body, and the sieve holes on the surface of the isolation plate 24 are located inside the discharge port 12;

[0047] On the other hand, the top edge of the impact plate 23 is rotatably connected to the inner wall of the machine body 1, and there is a movable gap between the outer surface of the impact plate 23 and the inner wall of the machine body 1, and the second spring 43 is arranged between the movable gaps.

[0048] In the present invention, the back of the counter-attack plate 23 is connected to the inner wall of the machine body 1 by a No. 2 spring 43, and its upper edge is rotatably connected to the inner wall of the machine body 1, so that the counter-attack plate 23 can rebound and swing to a certain extent around the rotation connection of its upper edge, and the top of the discharge port 12 is fixed to the lower surface of the isolation plate 24, which is convenient for the vibration to be transmitted between the discharge port 12 and the isolation plate 24. At the same time, the side of the discharge port 12 does not contact the machine body 1, and the lower surface of the isolation plate 24 and the inner wall of the machine body 1 are supported by the No. 1 spring 42, which can avoid reducing and weakening the vibration transmitted to the outer shell of the machine body 1, and avoid excessive external vibration amplitude when the machine body 1 is running. On the one hand, the isolation plate 24 and the impact plate 23 are connected by a rubber interlayer 44, which can prevent the isolation plate 24 and the impact plate 23 from colliding with each other during vibration, and at the same time isolate the cavity inside the body 1 to prevent the gypsum material from entering the gap between the isolation plate 24 and the impact plate 23, and transmit the vibration of the isolation plate 24 itself to the impact plate 23. Therefore, when the vibrator 41 is started, it can drive the discharge port 12, the isolation plate 24 and the impact plate 23 to vibrate together to prevent the gypsum material from adhering to the surfaces of the three and forming a blockage, and at the same time improve the screening speed of the powdered gypsum material on the surface of the isolation plate 24 to avoid the blockage of the sieve holes.

[0049] Furthermore, the connection between the upper and lower ends of the discharge port 12 and the machine body 1 and the drying device is made of soft rubber material. A vibration seat 46 is provided on one side of the discharge port 12. The vibration seat 46 and the machine body 1 are fixedly connected by a No. 3 spring 47. One side of the vibration seat 46 is connected to the discharge port 12 by a connecting rod. The No. 2 vibrator 4142 is installed on the surface of the vibration seat 46.

[0050] In the present invention, the No. 2 vibrator 4142 is installed on the vibration seat 46 on the side of the discharge port 12. The No. 3 spring 47 between the vibration seat 46 and the body 1 can absorb and buffer the vibration emitted by the No. 2 vibrator 4142 and the vibration seat 46 to protect the body 1. At the same time, the No. 2 vibrator 4142 and the discharge port 12 are connected by a connecting rod, so that the vibration of the No. 2 vibrator 4142 can be transmitted to the discharge port 12, thereby shaking off the gypsum powder hanging on the inner wall of the discharge port 12, and at the same time hindering the adhesion of the gypsum powder to avoid clogging of the discharge port 12, thereby affecting the subsequent process. On the other hand, the connection between the upper and lower ends of the discharge port 12 and the body 1 and the drying device is made of soft rubber material. The rubber material is elastic and can maintain the sealing of the upper and lower ends of the discharge port 12, avoiding the leakage of gypsum powder while absorbing the vibration movement of the discharge port 12 itself.

[0051] Furthermore, the drying device 5 includes a drying pipeline 51, a hot air blower 52, a transport auger 53 and a second motor 54;

[0052] The upper side of one end of the drying pipe 51 is connected to the discharge port 12, the hot air blower 52 is fixed to the end of the drying pipe 51 below the discharge port 12, and the air outlet is connected to the end of the drying pipe 51, the transport auger 53 is located inside the drying pipe 51, and the length is equivalent to that of the drying pipe 51, the end of the transport auger 53 away from the discharge port 12 is fixedly connected to the No. 2 motor 54, and the lower side of the end of the drying pipe 51 near the No. 2 motor 54 is provided with a drying outlet 55.

[0053] In the present invention, the powdered gypsum material falls from the discharge port 12 to one end of the drying pipe 51, and the hot air blower 52 introduces dry hot air into the end of the drying pipe 51 to dry the powdered gypsum material, so that the gypsum material completes preliminary drying and dehydration, and at the same time blows the gypsum material to the other end of the drying pipe 51, and discharges the gypsum material from the drying outlet 55 to enter the next process. At the same time, in order to more effectively discharge the gypsum material from the drying outlet 55 without blocking the drying pipe 51, a transport auger 53 is also provided in the drying pipe 51, which is driven by the second motor 54 at the end, and its transport direction is From the gypsum material inlet end below the discharge port 12 to the drying outlet 55 end, the auxiliary gypsum material is discharged from the drying outlet 55. On the other hand, the transport auger 53 hinders the movement of the gypsum material in the drying pipe 51, preventing the gypsum material powder from passing through the drying pipe 51 too quickly to reach the drying outlet 55 under the action of the airflow of the hot air blower 52, so that the gypsum material can be fully heated in the drying pipe 51 and initially dehydrated. At the same time, controlling the rotation speed of the second motor 54 can also control the rotation speed of the auger blades of the transport auger 53, thereby controlling the discharge speed at the drying outlet 55.

[0054] Furthermore, the blade surface of the transport auger 53 is a metal mesh.

[0055] In the present invention, the meshed blades of the transport auger 53 have little obstruction to the air flow blown out by the hot air blower 52 in the drying duct 51, so that the hot air flow is normally blown into the drying duct 51 from the air outlet of the hot air blower 52 and blown out from the drying outlet 55 to form an induced air flow. On the other hand, the meshed blades can also play a role in breaking up and splitting the gypsum material when transporting it, thereby preventing the broken gypsum material from agglomerating into blocks again in the drying duct 51.
