Description

Technical Field

[0001] The present invention relates to the technical field of grinding devices, and more particularly to a slag powder grinding device which is convenient for discharging. Background Art

[0002] Slag is a by-product of the blast furnace iron-making process, and slag powder is made from slag through processing and refining. The main purpose of slag powder is to be mixed with cement, which can greatly improve the various performances of cement concrete. It has been widely used in the existing technology. The production of slag powder requires grinding equipment to grind it into powder. The existing grinding equipment mainly uses grinding mills for grinding. Among them, vertical grinding mills are widely used because they occupy less space and have high grinding efficiency.

[0003] Although the existing vertical grinding mill can complete the grinding work of slag well, in the actual operation process, in order to facilitate the discharge of the ground slag powder from the upper end of the vertical grinding mill, the feed pipe is mostly set at an angle.

At the same time, due to the more concentrated discharge, the slag is easy to accumulate in the middle of the upper surface of the rotating seat, resulting in low processing efficiency.

[0034] The subject matter described herein will now be discussed with reference to example implementations. It should be understood that the discussion of these implementations is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the present specification. Various examples may omit, replace, or add various processes or components as needed. In addition, the features described in some examples may also be combined in other examples.

[0035] like Figure 3 , Figure 6 , Figure 7 As shown, this embodiment discloses a slag powder grinding device that is convenient for discharging, comprising: a shell 100; a feed pipe 101 is fixedly connected to the shell 100;

[0036] The grinding mechanism 200 is arranged on the housing 100: the grinding mechanism 200 comprises a rotating seat 201 rotatably arranged on the housing 100, a pair of grinding wheels 203 are rotatably arranged on the housing 100, and each grinding wheel 203 is in rolling cooperation with the rotating seat 201;

[0037] The crushing mechanism 300 is arranged in the shell 100. The crushing mechanism 300 includes a receiving tube 301 arranged between the rolling wheel 203 and the feed pipe 101, and the feed port of the receiving tube 301 is arranged opposite to the lower tube port of the feed pipe 101. The upper surface of the rotating seat 201 is fixedly connected with a reciprocating screw rod 302, and the upper end of the reciprocating screw rod 302 is fixedly connected with a central axis 303. The central axis 303 is rotatably connected to the receiving tube 301, and the central axis 303 extends on the shaft body in the receiving tube 301 and is fixedly connected with a plurality of crushing cones 304. The reciprocating screw rod 302 is threadedly connected with an annular block 305, and a pair of pull rods 306 are hinged on the annular block 305. A pair of sealing doors 307 are hinged at the bottom of the receiving tube 301, and each pull rod 306 is hinged to the lower surface of the corresponding sealing door 307.

[0038] The working principle and beneficial effects of the above technical solution are:

[0039] First, the slag to be ground is fed into the receiving tube 301 through the feed pipe 101. Under the action of gravity, the slag slides into the receiving tube 301 through the feed pipe 101. The rotating rotating seat 201 drives the reciprocating screw 302 and the center shaft 303 to rotate synchronously. The center shaft 303 drives multiple crushing cones 304 to rotate synchronously, and the slag in the receiving tube 301 is preliminarily crushed. At the same time, the stirring action of the crushing cone 304 makes the slag spread more evenly in the receiving tube 301.

[0040] At the same time, the reciprocating screw rod 302 rotates to drive the annular block 305 to move, and the annular block 305 drives the pull rod 1 306 to move. At the same time, the annular block 305 is restricted by the pull rod 1 306 in its moving trajectory and can only move back and forth in the vertical direction. When the annular block 305 moves downward, it pulls the two pull rods 1 306, so that the angle between the two pull rods 1 306 gradually becomes smaller, and then pulls the two sealing doors 307, so that the two sealing doors 307 rotate, and the bottom of the receiving tube 301 is no longer blocked, and the slag in the receiving tube 301 passes through the sealing doors 307. The two opened channels are poured out to both sides more evenly, and the rotating crushing cone 304 can continuously stir the slag in the receiving tube 301 to prevent it from accumulating in the receiving tube 301 so that it can be discharged smoothly. When the annular block 305 moves upward, the sealing door 307 seals the bottom of the receiving tube 301 again, and this cycle is repeated, using the receiving tube 301 as a transfer station to perform preliminary crushing of the slag while intermittently discharging the slag onto the rotating seat 201, and grinding it by the rotating rotating seat 201 and the rolling wheel 203.

[0041] like Figure 6 , Figure 7As shown, in a specific embodiment: a pushing mechanism 400 is arranged on the rotating seat 201, and the pushing mechanism 400 includes a protective tube 401 fixedly connected to the rotating seat 201, the protective tube 401 is slidably connected to the annular block 305, a pair of pull rods 402 are hinged on the annular block 305, and a pair of sliders 403 are slidably arranged on the upper surface of the rotating seat 201, each pull rod 402 is hinged to the corresponding slider 403, and the opposite sides of the two sliders 403 are fixedly connected with push plates 404.

[0042] The working principle and beneficial effects of the above technical solution are as follows: when the annular block 305 moves downward, it drives the two pull rods 402 to move, so that the angle between the two pull rods 402 gradually increases, and the pull rod 402 drives the corresponding slider 403 to move, so that the slider 403 and the rotating seat 201 slide relative to each other, and the two sliders 403 move away from each other, driving the two push plates 404 to move, pushing the slag on the moving path of the push plates 404 to the edge of the rotating seat 201, so that it can be smoothly crushed by the crushing wheel 203.

[0043] like Figure 7 As shown, in a specific embodiment: the feed port of the receiving cylinder 301 gradually narrows from top to bottom, and the cross-section of the cylinder body is an isosceles trapezoid, the cross-section of the protective cylinder 401 is an isosceles triangle, each push plate 404 is configured as an arc plate, and the side of the push plate 404 close to the protective cylinder 401 is treated with a curved transition.

[0044] The working principle and beneficial effects of the above technical solution are as follows: by setting the feed port of the receiving tube 301 to a shape that gradually narrows from top to bottom, the slag fed in through the feed pipe 101 can be better received; and by setting the cross-section of the tube body of the receiving tube 301 to an isosceles trapezoid, the space between the two rolling wheels 203 can be more fully utilized to accommodate more slag; and by setting the cross-section of the tube body of the protective tube 401 to an isosceles triangle, a slope is formed by the tube body of the protective tube 401, and the slag falling on the slope rolls toward the edge of the rotating seat 201 under the action of gravity, avoiding To prevent it from accumulating in the middle of the upper surface of the rotating seat 201, thereby accelerating the grinding efficiency, when the two push plates 404 move away from each other, the slag or slag powder close to the protective tube 401 can be smoothly pushed outward because the side away from the protective tube 401 has no curved surface transition treatment. When the two push plates 404 move toward each other, the side close to the protective tube 401 has a curved surface transition treatment. When there is slag between the push plates 404 and the protective tube 401, the slag will be squeezed and squeezed upward along the curved surface of the push plates 404, which can effectively prevent the slag from affecting the normal use of the push plates 404.

[0045] like Figure 8As shown, in a specific embodiment: a plurality of crushing cones 309 are fixedly connected in the receiving tube 301, the plurality of crushing cones 309 are layered from top to bottom, and the plurality of crushing cones 309 in each layer are equidistantly arranged, and the distance between two adjacent crushing cones 309 in a single layer decreases from the upper layer to the lower layer.

[0046] The working principle and beneficial effects of the above technical solution are as follows: the multiple crushing cones 309 in the receiving tube 301 cooperate with the crushing cone 1 304 to further improve the crushing effect. At the same time, since the multiple crushing cones 309 are arranged in layers, the falling speed of the slag can be slowed down, so that the slag can be more fully in contact with the crushing cone 1 304 and the crushing cone 2 309 during the process of entering the receiving tube 301. Moreover, since the distance between the crushing cones 309 located in the upper layer is larger than that between the crushing cones 309 located in the lower layer, it can play a role of layer-by-layer screening. Only the slag that is crushed within the set range can fall onto the rotating seat 201 and be ground into slag powder, thereby preventing the larger slag from falling onto the rotating seat 201 and affecting the smooth progress of the grinding work.

[0047] like Figure 5 As shown, in a specific embodiment: a pair of symmetrically arranged connecting rods 308 are fixedly connected to the inner wall of the shell 100 , and each connecting rod 308 is fixedly connected to the receiving tube 301 .

[0048] The working principle and beneficial effects of the above technical solution are as follows: the connecting rod 308 is used to fix the receiving tube 301 to improve its stability.

[0049] like Figure 2 , Figure 5 As shown, in a specific embodiment: a base 102 is fixedly connected to the lower side of the shell 100, a reduction motor 103 is fixedly connected to the base 102, an output shaft of the reduction motor 103 is fixedly connected to the middle of the lower surface of the rotating seat 201, and a driving motor 104 for driving the reduction motor 103 to rotate is provided on one side of the base 102.

[0050] The working principle and beneficial effects of the above technical solution are as follows: the drive motor 104 is started, the output shaft of the drive motor 104 rotates, driving the reduction motor 103 to operate, and further driving the rotating seat 201 to rotate.

[0051] like Figure 3As shown, in a specific embodiment: both sides of the base 102 are rotatably connected with mounting plates 105, each mounting plate 105 is rotatably connected with a rotating shaft 106, the rotating shaft 106 is fixedly connected to the rolling wheel 203, the mounting plate 105 is fixedly connected with a driving motor 2 107, the output shaft of each driving motor 2 107 is fixedly connected to the corresponding rotating shaft 106, a pair of mounting frames 108 are fixedly connected to the base 102, each mounting frame 108 is hinged with an electric telescopic rod 109, and the moving end of the electric telescopic rod 109 is hinged to the corresponding mounting frame 108.

[0052] The working principle and beneficial effects of the above technical solution are as follows: start the two electric telescopic rods 109, the mobile ends of the electric telescopic rods 109 move, driving the two mounting plates 105 to rotate, thereby delivering the corresponding rolling wheels 203 into the shell 100, or removing them from the shell 100, so as to facilitate their inspection or cleaning. During operation, start the drive motor 107, the output shaft of the drive motor 107 rotates, driving the rotating shaft 106 to rotate, and then driving the rolling wheels 203 to rotate synchronously.

[0053] like Figure 5 As shown, in a specific embodiment: an air ring 204 is installed on the base 102 and is arranged concentrically with the rotating base 201 , and an air inlet pipe 205 is fixedly connected to the base 102 and is in communication with the air ring 204 .

[0054] The working principle and beneficial effects of the above technical solution are as follows: the air inlet pipe 205 guides the hot air into the air ring 204, the air outlet of the air ring 204 is set upward, and the hot air is stored and sprayed out in a ring shape, thereby blowing up the ground slag powder.

[0055] like Figure 3 As shown, in a specific embodiment: a filter cover 206 is fixedly connected inside the shell 100, and a discharge pipe 207 is fixedly connected to the outside of the shell 100 and communicated with the discharge pipe.

[0056] The working principle and beneficial effects of the above technical solution are as follows: the air outlet of the air ring 204 blows hot air upward to blow up the ground slag powder, and the slag powder that meets the particle size standard passes through the filter cover 206 and is then discharged through the discharge pipe 207, which is convenient for discharging and allows it to quickly enter the next process. The slag powder with a larger particle size is intercepted and falls downward to the rotating seat 201 under the action of gravity for secondary grinding.

[0057] like Fig. 9 As shown, in a specific embodiment: an inspection door 208 is rotatably connected to the housing 100 , and an observation window 202 is installed on the inspection door 208 .

[0058] The working principle and beneficial effects of the above technical solution are as follows: the design of the inspection door 208 facilitates the staff to clean the slag powder remaining inside, and the setting of the observation window 202 facilitates the observation of whether the device is operating normally and whether there is any slag or slag powder remaining.

[0059] Working principle: First, the slag to be ground is fed in through the feed pipe 101. Under the action of gravity, the slag slides into the receiving tube 301 through the feed pipe 101. The driving motor 104 drives the reduction motor 103 to operate, thereby driving the rotating seat 201 to rotate. The rotating seat 201 drives the reciprocating screw 302 and the center shaft 303 to rotate synchronously. The center shaft 303 drives multiple crushing cones 304 to rotate synchronously, and the slag in the receiving tube 301 is preliminarily crushed. At the same time, the stirring action of the crushing cone 304 makes the slag spread more evenly in the receiving tube 301.

[0060] Furthermore, the multiple crushing cones 309 in the receiving tube 301 cooperate with the crushing cone 1 304 to further improve the crushing effect. At the same time, since the multiple crushing cones 309 are arranged in layers, the falling speed of the slag can be slowed down, so that the slag can be more fully in contact with the crushing cone 1 304 and the crushing cone 2 309 during the process of entering the receiving tube 301. Moreover, since the distance between the crushing cones 309 located in the upper layer is larger than that between the crushing cones 309 located in the lower layer, it can play a role of layer-by-layer screening. Only the slag that is crushed within the set range can fall onto the rotating seat 201 and be ground into slag powder, thereby preventing larger slag from falling onto the rotating seat 201 and affecting the smooth progress of the grinding work.

[0061] At the same time, the reciprocating screw rod 302 rotates to drive the annular block 305 to move, and the annular block 305 drives the pull rod 1 306 to move. At the same time, the annular block 305 is restricted by the pull rod 1 306 in its moving trajectory and can only move back and forth in the vertical direction. When the annular block 305 moves downward, it pulls the two pull rods 1 306, so that the angle between the two pull rods 1 306 gradually becomes smaller, and then pulls the two sealing doors 307, so that the two sealing doors 307 rotate and no longer block the bottom of the receiving tube 301. The slag in the receiving tube 301 is opened through the two channels opened by the sealing doors 307, which is relatively even. The slag is evenly scattered to both sides, so that the slag is evenly scattered on the upper surface of the rotating seat. The rotating crushing cone 304 can continuously stir the slag in the receiving tube 301 to prevent it from accumulating in the receiving tube 301, so that it can be discharged smoothly. When the annular block 305 moves upward, the sealing door 307 seals the bottom of the receiving tube 301 again, and this cycle is repeated. The receiving tube 301 is used as a transfer station to perform preliminary crushing of the slag, and at the same time, the slag is intermittently and evenly scattered onto the rotating seat 201, and is ground by the rotating rotating seat 201 and the rolling wheel 203.

[0062] On the contrary, when the annular block 305 moves downward, it drives the two pull rods 402 to move, so that the angle between the two pull rods 402 gradually increases, and the pull rod 402 drives the corresponding slider 403 to move, so that the slider 403 and the rotating seat 201 slide relative to each other, and the two sliders 403 move away from each other, driving the two push plates 404 to move, pushing the slag on the moving path of the push plates 404 to the edge of the rotating seat 201, so that it can be smoothly crushed by the crushing wheel 203.

[0063] The above describes an embodiment of the present invention, but this embodiment is not limited to the above specific implementation methods. The above specific implementation methods are merely illustrative and not restrictive. Under the guidance of this embodiment, ordinary technicians in this field can also make many forms, all of which are protected by this embodiment.
