Description

Technical Field

[0001] The invention relates to the field of crushing equipment, in particular to raw ore crushing equipment. Background Art

[0002] The double-roll crusher is used to process small stones in the second and third crushing stages. The crushing rollers are divided into fixed rollers and movable rollers, which are used to cushion the crushing of harder or larger stones. Although this can protect the safety of the equipment, the crushed stones are of different sizes, affecting product quality.

[0003] The double-roll crusher is a mechanical device specially used for secondary and tertiary crushing operations. It is mainly used to process small stones that fail to reach the ideal particle size during the primary crushing process. The core components of this crusher are two relatively rotating crushing rollers, one of which is a fixed roller and the other is a movable roller. The fixed roller and the movable roller rotate around their respective axes, and the fixed roller does not translate, while the movable roller moves away from or close to the fixed roller under the action of the driving device. This design enables the double-roll crusher to effectively crush the harder parts of the stones or larger stones during the crushing process.

[0004] During the crushing process, a relatively small crushing gap is formed between the fixed roller and the movable roller. When the stone enters this gap, it will be gradually crushed into smaller particles due to the squeezing and shearing force of the two rollers. However, due to the different hardness and size of the stones, the size of the crushed stone particles will also be different. This different size of stone particles will affect the quality of the final product, because many industrial applications have strict requirements on the particle size of the stone.

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below through embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0032] The serial numbers assigned to the components herein, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in the present invention, unless otherwise specified, include direct and indirect connections (couplings). In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention.

[0033] like Figures 1 to 5 As shown, the raw ore crushing equipment according to the embodiment of the present invention includes a shell, a fixed roller assembly, a movable roller assembly, a first discharge flow channel 110 and a second discharge flow channel 111.

[0034] The top of the housing has a feed port 101, and the bottom of the housing has a discharge port 105 (see Figure 1 and Figure 2 ).

[0035] The fixed roller assembly is disposed inside the housing and has a fixed roller 106 extending along a first direction (direction L1) (see Figure 5 ). The first direction is the axial direction and is arranged horizontally.

[0036] The movable roller assembly is arranged inside the housing and has a movable roller 107 arranged in parallel with the fixed roller 106. The movable roller 107 can move in the first direction (the direction of L1) and in the second direction (the direction of L2) at the same time. The gap between the fixed roller 106 and the movable roller 107 constitutes a crushing channel (see Figure 5 ). The second direction is horizontally arranged and perpendicular to the first direction.

[0037] like Figure 6 As shown, the first discharge channel 110 extends along the second direction and is connected to the first end of the crushing channel. The second discharge channel 111 extends along the second direction and is connected to the second end of the crushing channel.

[0038] When the crushing channel between the fixed roller 106 and the movable roller 107 is mixed with hard materials, the movable roller 107 can move along the first direction and along the second direction (the direction of L2) at the same time to reduce the area of ​​the overlapping region between the fixed roller 106 and the movable roller 107 in the axial direction (i.e., the first direction), so that part of the hard materials leave the first discharge channel 110 and the second discharge channel 111, thereby reducing the amount of hard materials between the fixed roller 106 and the movable roller 107. At the same time, the total pressure between the fixed roller shaft 1061 and the movable roller shaft 1071 remains unchanged, thereby increasing the pressure of the fixed roller 106 and the movable roller 107 on the mixed single hard materials, thereby increasing the crushing effect and making the crushed materials more uniform. In addition, the reduction of the overlapping area can also reduce the amount of new falling materials falling between the fixed roller shaft 1061 and the movable roller shaft 1071, increase the force acting on a single stone, and increase the crushing effect.

[0039] For example, assuming that the pressure remains unchanged, originally 10 stones bear a pressure of 1000N from the fixed roller 106 and the movable roller 107, and each stone bears a pressure of 100N. Now there are 5 stones left, and each stone needs to bear a pressure of 200N. Therefore, the pressure on each stone increases.

[0040] Assume that before the material fell, 5 stones were bearing a force of 1000N, and now 5 new stones fell and fell between the fixed roller 106 and the movable roller 107, then each stone (now there are 10 stones in total) will bear a force of 100N, and if the overlapping area of ​​the rollers is reduced, 2 of the 5 stones that fell leave the first discharge channel 110 and the second discharge channel 111, then there will be 8 stones bearing a force of 1000N, and each stone will bear a force of 125N. Therefore, the total number of stones is reduced, which can increase the force acting on a single stone and enhance the crushing effect.

[0041] For example, Figure 4 As shown, the housing includes a crusher frame 102 and a supporting base plate 109 .

[0042] The crusher frame 102 is fixed to the ground to provide the necessary support force to ensure the stable operation of the entire equipment. The crusher frame 102 is used to support the support bottom plate 109. The feed port 101 is arranged on the top of the crusher frame 102 and is fixedly connected to the crusher frame 102. The crusher frame 102 is generally in an inverted U shape and has two opposite openings in a first direction. The crusher frame 102 is provided with an end cover 103 at the opening (see Figure 1 ) to prevent dust, debris and other impurities from entering the crusher frame 102 and affecting the normal operation and service life of the equipment.

[0043] The support bottom plate 109 is disposed at the lower part of the crusher frame 102. The discharge port 105 is disposed on the support bottom plate 109 and is fixedly connected to the crusher frame 102. The support bottom plate 109 has a first limiting groove 1091 and a second limiting groove 1092 (see Fig.10 ). The first limiting groove 1091 and the second limiting groove 1092 are arranged in parallel and inclined.

[0044] Specifically, the first end of the first limiting groove 1091 is farther away from the second discharge channel 111 than the second end of the first limiting groove 1091, and is farther away from the axis of the fixed roller 106 than the second end of the first limiting groove 1091 (that is, the first limiting groove 1091 is along the Figure 6 The movable roller 107 is inclined in the upper left-lower right direction, so that the movable roller limit plate 1073 introduced later can be guided to approach the first end of the fixed roller 106 while also being away from the axis of the fixed roller 106, thereby expanding the distance between the fixed roller 106 and the movable roller 107 (i.e., the width of the crushing channel).

[0045] The first end of the second limiting groove 1092 is closer to the movable roller limiting plate 1073 described later than the second end of the second limiting groove 1092, and is farther away from the axis of the fixed roller 106 than the second end of the second limiting groove 1092 (that is, the second limiting groove 1092 is along the axis of the fixed roller 106). Figure 6 The movable roller 1072 is inclined in the upper left-lower right direction, so that it can guide the movable roller baffle plate 1072 introduced later to move away from the second end of the fixed roller 106 and also away from the axis of the fixed roller 106, thereby expanding the distance between the fixed roller 106 and the movable roller 107 (that is, the width of the crushing channel).

[0046] The supporting bottom plate 109 has a drop-in opening extending along a first direction, and the drop-in opening is located in a crushing channel formed by the fixed roller 106 and the movable roller 107. The discharge port 105 is installed on the lower surface of the supporting bottom plate 109 and is located below the drop-in opening, so that the crushed material falls through the drop-in opening to the discharge port 105, thereby being collected.

[0047] The support bottom plate 109 is used to support the fixed roller material baffle plate 1063, the fixed roller limiting plate 1062, the movable roller limiting plate 1073, the movable roller material baffle plate 1072 and the buffer bracket 1081 which will be described later.

[0048] For example, Figure 3 and Figure 5 As shown, the fixed roller assembly includes: a fixed roller material blocking plate 1063, a fixed roller limiting plate 1062 and the above-mentioned fixed roller 106.

[0049] The fixed roller material baffle plate 1063 is located at the first end of the fixed roller 106, and the fixed roller limiting plate 1062 is located at the second end of the fixed roller 106. The fixed roller material baffle plate 1063 and the fixed roller limiting plate 1062 are fixed on the supporting base plate 109. The fixed roller 106 can be rotatably installed on the fixed roller material baffle plate 1063 and the fixed roller limiting plate 1062 through the fixed roller rotating shaft 1061. The fixed roller 106 can rotate around its own axis relative to the fixed roller material baffle plate 1063 and the fixed roller limiting plate 1062.

[0050] The fixed roller material blocking plate 1063, the fixed roller limiting plate 1062 and the fixed roller 106 cannot move along the first direction or along the second direction.

[0051] Specifically, Figure 5 As shown, the fixed roller limiting plate 1062 includes a fixed roller limiting plate bottom plate 10621, a fixed roller limiting plate mounting plate 10622 and a fixed roller limiting plate sliding plate 10623 which are formed as one piece.

[0052] The fixed roller limiting plate bottom plate 10621 is horizontally arranged and installed on the supporting bottom plate 109 .

[0053] The fixed roller limiting plate mounting plate 10622 extends along the second direction and has a predetermined height. The fixed roller limiting plate mounting plate 10622 is used to mount the fixed roller 106 .

[0054] The fixed roller limiting plate sliding plate 10623 extends along the first direction and has a predetermined height. The fixed roller limiting plate sliding plate 10623 has a fixed roller chute extending along the first direction. The fixed roller chute is used for sliding connection with the second discharge channel 111 .

[0055] For example, Figure 3 and Figure 5 As shown, the movable roller assembly includes: a movable roller limiting plate 1073, a movable roller material blocking plate 1072 and the above-mentioned movable roller 107.

[0056] The movable roller limiting plate 1073 is fixed on the supporting base plate 109 and is located at the first end of the movable roller 107. The movable roller limiting plate 1073 has a first guide shaft corresponding to the first limiting groove 1091. The first guide shaft is located in the first limiting groove 1091, so that the movable roller limiting plate 1073 can move along the second direction while moving along the first direction.

[0057] Specifically, Figure 5 As shown, the movable roller limiting plate 1073 includes a movable roller limiting plate bottom plate 10731, a movable roller limiting plate mounting plate 10732 and a movable roller limiting plate sliding plate 10733 which are formed as one body.

[0058] The movable roller limiting plate bottom plate 10731 is arranged horizontally and mounted on the supporting bottom plate 109. The movable roller limiting plate bottom plate 10731 has an upwardly extending mounting post 10734, and the mounting post 10734 is used to connect the buffer 108 introduced later.

[0059] The movable roller limiting plate mounting plate 10732 extends along the second direction and has a predetermined height. The movable roller limiting plate mounting plate 10732 is used to mount the movable roller 107 .

[0060] The movable roller limiting plate sliding plate 10733 extends along the first direction and has a predetermined height. The movable roller limiting plate sliding plate 10733 has a movable roller chute extending along the first direction. The movable roller chute is used for sliding connection with the first discharge channel 110 .

[0061] The movable roller material baffle plate 1072 is fixed on the supporting base plate 109 and is located at the second end of the movable roller 107. The movable roller material baffle plate 1072 has a second guide shaft corresponding to the second limiting groove 1092. The second guide shaft is located in the second limiting groove 1092, so that the movable roller material baffle plate 1072 can move along the second direction while moving along the first direction.

[0062] Exemplarily, the second discharge channel 111 is slidably connected to the movable roller baffle plate 1072 so that the movable roller baffle plate 1072 can move along the second direction relative to the second discharge channel 111, but cannot move along the first direction relative to the second discharge channel 111, that is, the process of the movable roller baffle plate 1072 moving along the first direction and the second direction relative to the supporting bottom plate 109 can enable the movable roller baffle plate 1072 to move along the second direction relative to the second discharge channel 111 without causing the second discharge channel 111 to move along the second direction, while pulling the second discharge channel 111 to move along the first direction.

[0063] For example, Figures 5 to 8 As shown, the first end of the first discharge channel 110 is slidably connected to the movable roller limiting plate 1073 so that the movable roller limiting plate 1073 can move along the first direction relative to the first discharge channel 110 .

[0064] Specifically, the first end of the first discharge flow channel 110 is installed in the movable roller slide groove of the movable roller limit plate sliding plate 10733 of the movable roller limit plate 1073, so that the movable roller limit plate 1073 can move along the first direction relative to the first discharge flow channel 110, and can pull the first discharge flow channel 110 to move along the second direction. The first discharge flow channel 110 cannot move along the first direction.

[0065] For example, Figures 5 to 8As shown, the first end of the second discharge channel 111 is slidably connected to the fixed roller limit plate 1062, so that the second discharge channel 111 can move along the first direction relative to the fixed roller limit plate 1062, but cannot move along the second direction.

[0066] Specifically, the first end of the second discharge channel 111 is installed in the fixed roller slide groove of the fixed roller limit plate sliding plate 10623 of the fixed roller limit plate 1062, so that the second discharge channel 111 can move along the first direction relative to the fixed roller limit plate 1062, and cannot move along the second direction.

[0067] For example, Figure 5 and Figure 6 As shown, the raw ore crushing equipment of the present invention further includes: a buffer bracket 1081 and a buffer 108.

[0068] The buffer bracket 1081 is fixed to the crusher frame 102 .

[0069] The first end of the buffer 108 is fixedly connected to the buffer bracket 1081 , and the second end of the buffer 108 is fixedly connected to the mounting column 10734 of the movable roller limiting plate bottom plate 10731 of the movable roller limiting plate 1073 .

[0070] The first end of the buffer 108 is further away from the second end of the fixed roller shaft 1061 (i.e., the second end of the crushing channel) than the second end of the buffer 108, and is further away from the axis of the fixed roller shaft 1061 (i.e., the axis of the buffer 108 along the crushing channel) than the second end of the buffer 108. Figure 6 (upper left - lower right direction tilt setting).

[0071] The buffer 108 is in a constant compression state and provides elastic support force to the movable roller limit plate 1073 so that the movable roller limit plate 1073 and the movable roller 107 are reset.

[0072] In an exemplary embodiment, the buffer 108 is a spring buffer, and the type of the buffer 108 is not limited thereto, and it can be any type in the prior art as long as it can achieve the above functions.

[0073] For example, Figure 2 , Figure 3 and Fig. 9 As shown, the raw ore crushing device of the present invention further includes a first recovery port 104, which is disposed on the crusher frame 102 and is slidably connected to the second end of the first discharge flow channel 110, so that the first discharge flow channel 110 can move along the second direction relative to the first recovery port 104. The first end of the first discharge flow channel 110 is higher than the second end of the first discharge flow channel 110, so that the material falls.

[0074] For example, Figure 2 and Figure 3 As shown, the raw ore crushing equipment of the present invention further includes a second recovery port 112, which is disposed on the crusher frame 102 and is slidably connected to the second end of the second discharge flow channel 111, so that the second discharge flow channel 111 can move along the first direction relative to the second recovery port 112. The first end of the second discharge flow channel 111 is higher than the second end of the second discharge flow channel 111, so that the material falls.

[0075] Exemplarily, the raw ore crushing device of the present invention further includes a driving device (not shown in the figure), which is connected to the fixed roller 106 and the movable roller 107 and can drive the fixed roller 106 and the movable roller 107 to rotate in opposite directions around their respective axes (see Figure 4 ) to crush the materials.

[0076] In an exemplary embodiment, the driving device is a motor, but the type of the driving device is not limited thereto and can be any type in the prior art as long as it can achieve the above functions.

[0077] Only one driving device may be provided, and the fixed roller 106 and the movable roller 107 may be driven to rotate in opposite directions around their respective axes through different transmission devices.

[0078] Two driving devices may also be provided, and the two driving devices drive the fixed roller 106 and the movable roller 107 respectively.

[0079] The operation of the raw ore crushing equipment of the present invention will be described below with reference to the accompanying drawings.

[0080] The driving device drives the fixed roller 106 and the movable roller 107 to rotate in opposite directions around their respective axes. Figure 4 Rotate in the direction of arrow P and arrow Q.

[0081] Materials are fed from the feed port 101 , crushed between the fixed roller 106 and the movable roller 107 , and finally discharged from the discharge port 105 .

[0082] When there are large particles and hard stones, the rotating fixed roller 106 and the movable roller 107 cannot crush the stones, and give the stones a force to cross the tangent line of the rollers, causing the large particles and hard stones to produce a reaction force. The reaction force acts on the fixed roller 106 and the movable roller 107, and the fixed roller 106 cannot move in the horizontal direction, causing the movable roller 107 to move away from the fixed roller 106, thereby causing the movable roller baffle plate 1072 and the movable roller limit plate 1073 to move away from the axis where the fixed roller 106 is located.

[0083] In the process that the movable roller material blocking plate 1072 and the movable roller limiting plate 1073 move away from the axis of the fixed roller 106, due to the guidance of the first limiting groove 1091, the second limiting groove 1092 and the buffer 108, the movable roller material blocking plate 1072 and the movable roller limiting plate 1073 move along the first direction to approach the first end of the fixed roller 106 (that is, the movable roller 107 moves toward the first end of the fixed roller 106). Figure 6 ), thereby achieving Figure 5 and Figure 6 Status to Figure 7 and Figure 8 state transition.

[0084] like Figure 6 and Figure 8 As shown, the overlapping area of ​​the fixed roller 106 and the movable roller 107 in the first direction (ie, the axial direction) becomes smaller, and the pressure exerted by the fixed roller 106 and the movable roller 107 on a single stone is increased.

[0085] At the same time, the movable roller limiting plate 1073 pulls the first discharge channel 110 to move along the second direction (that is, the first discharge channel 110 moves in the second direction). Figure 6 and Figure 8 The first discharge channel 110 moves to the right in the middle of the fixed roller 106 to ensure that the first discharge channel 110 can fit the movable roller 107, and the movable roller baffle plate 1072 pulls the second discharge channel 111 to move along the first direction toward the first end of the fixed roller 106 (that is, the first discharge channel 110 moves to the right in the middle of the fixed roller 106). Figure 6 and Figure 8 The fixed roller 106 and the movable roller 107 move downward in the middle of the fixed roller 106, thereby guiding the stones in the non-overlapping areas at both ends of the fixed roller 106 and the movable roller 107 to the first discharge flow channel 110 and the second discharge flow channel 111, and discharge them from the first recovery port 104 and the second recovery port 112 to avoid contaminating the crushed stones.

[0086] In the process that the movable roller limit plate 1073 moves away from the axis where the fixed roller 106 is located, the movable roller limit plate 1073 further compresses the buffer 108, and the elastic force of the further compressed buffer 108 acts on the movable roller limit plate 1073 and the movable roller 107 to move toward the direction of approaching the fixed roller 106 and approaching the axis where the fixed roller 106 is located (that is, toward Figure 8 ), and the cycle repeats.

[0087] In addition, when the movable roller 107 moves along the first direction (ie, the axial direction), it drives the material to move in the first direction, giving the material a rotational force to change the contact position between the fixed roller 106, the movable roller 107 and the material, reducing material slippage, thereby increasing the crushing effect.

[0088] The technical features of the above embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
