Description

Technical Field

[0001] This utility model relates to the field of sand making technology, and in particular to a vertical shaft impact dry sand making equipment. Background Technology

[0002] Dry sand making is a process for producing manufactured sand by crushing rocks. Its core process includes coarse crushing, medium crushing, sand making, screening and powder selection. It uses dry crushing and grading technology to control the sand particle size distribution. It does not require water washing and has the characteristics of strong environmental protection and low cost.

[0003] However, in the process of small-batch sand production, traditional sand production equipment mostly relies on a single crushing principle, which results in a large difference in crushing efficiency for raw materials with different hardness and particle size. Large particles are not fully crushed due to insufficient impact energy, leading to a large particle size range. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the prior art by proposing a vertical shaft impact dry sand making equipment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a vertical shaft impact dry sand making equipment, comprising a feed bin, a fine crushing bin, a conical bin, a base, and a stepper motor. The feed bin, fine crushing bin, and conical bin are fixedly installed in sequence. A grinding mechanism is fixedly connected at the middle position of the conical bin and the base. The grinding mechanism includes a pushing assembly, a grinding tool assembly, an orifice plate, a column bin, and a discharge assembly. The orifice plate is fixedly installed at the lower end of the column bin. The inner wall of the column bin has multiple sets of vertical side edges vertically distributed. The grinding tool assembly includes vertical cutters and horizontal cutters. Multiple sets of horizontal protrusions are welded to the outer side of each set of vertical cutters. Two sets of vertical cutters are vertically welded to the upper side of the horizontal cutters. The horizontal cutters are rotatably installed in the middle of the orifice plate and horizontally attached to the upper side of the orifice plate.

[0006] Preferably, the pushing assembly includes a vertical rod and a spiral fan blade. The vertical rod is vertically fixedly installed in the middle of the cross cutter, and the upper end of the vertical rod is rotatably connected to the upper side of the conical chamber.

[0007] Preferably, multiple sets of the spiral fan blades are fixedly connected to the outer ring surface of the upright, and the spiral fan blades are located inside the conical compartment.

[0008] Preferably, the discharge assembly includes a discharge port, a push plate, and a collection bin, and the cross cutter and the push plate are coaxially mounted at the output end of the stepper motor.

[0009] Preferably, the pusher plate is located below the perforated plate and is attached to the bottom of the inner cavity of the collection bin.

[0010] Preferably, the column bin is fixedly installed on the upper side of the collection bin, and the discharge port is fixedly installed at the outlet of the collection bin.

[0011] Preferably, the output end of the stepper motor is rotatably connected to the lower middle part of the collection bin, the collection bin is fixedly installed on the upper side of the base, and the stepper motor is fixedly installed inside the base.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, the vertical cutter moves in a circular motion inside the lower end pipe of the conical chamber. The horizontal protrusion of the vertical cutter cooperates with multiple sets of vertically distributed side edges on the inner wall of the cylindrical chamber. There is a small gap between the protrusion and the side edges, which further impacts and crushes the falling particles. The horizontal cutter rotates on the upper side of the perforated plate. Under the combined action of the two, the rock particles are ground into sand. Particles of the required particle size fall from the perforated plate into the collection bin. Particles of the required particle size continue to be ground until they fall into the collection bin, ensuring the uniformity of the sand particle size. At the same time, this equipment realizes multiple steps of medium crushing, sand making and screening in the dry sand making process. It can make sand and ensure the sand quality without the need for multiple devices.

[0014] 2. In this utility model, when the stepper motor rotates, the grinding assembly drives the upright to rotate inside the conical chamber. The spiral fan blades rotate spirally under the drive of the upright. The spiral fan blades are designed according to the internal dimensions and installation position of the conical chamber. Multiple sets of spiral fan blades rotate to convey the crushed rock particles downwards. The crushing efficiency of the fine crushing chamber is faster than that of the grinding assembly. As rock particles are continuously input, a certain amount of particles will accumulate inside the conical chamber. The pusher assembly is used to prevent the particles from clogging in the conical chamber and to apply a downward force to the particles, thereby improving the conveying and crushing efficiency.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides a vertical shaft impact dry sand making equipment, including a feed bin 1, a fine crushing bin 2, a conical bin 3, a base 5, and a stepper motor 6. The feed bin 1, fine crushing bin 2, and conical bin 3 are fixedly installed in sequence. A grinding mechanism 4 is fixedly connected at the middle position of the conical bin 3 and the base 5. The grinding mechanism 4 includes a pushing assembly, a grinding tool assembly 43, a perforated plate 44, a column bin 47, and a discharge assembly. The perforated plate 44 is fixedly installed at the lower end of the column bin 47. The inner wall of the column bin 47 has multiple sets of vertical side ribs 471 vertically distributed. The grinding tool assembly 43 includes vertical cutters 431 and horizontal cutters 432. Multiple sets of horizontal protrusions are welded to the outer side of each set of vertical cutters 431. The two sets of vertical cutters 431 are vertically welded to the upper side of the horizontal cutters 432. The horizontal cutters 432 are rotatably installed in the middle of the perforated plate 44 and horizontally attached to the upper side of the perforated plate 44.

[0023] The discharge assembly includes a discharge port 45, a push plate 46, and a collection bin 48. The cross cutter 432 and the push plate 46 are coaxially mounted on the output end of the stepper motor 6. The push plate 46 is located below the perforated plate 44 and is attached to the bottom of the inner cavity of the collection bin 48. The column bin 47 is fixedly mounted on the upper side of the collection bin 48. The discharge port 45 is fixedly mounted on the outlet of the collection bin 48. The output end of the stepper motor 6 is rotatably connected to the lower middle part of the collection bin 48. The collection bin 48 is fixedly mounted on the upper side of the base 5, and the stepper motor 6 is fixedly mounted inside the base 5.

[0024] The specific settings and functions of this embodiment are described below: Coarsely crushed rock particles are conveyed to the feed hopper 1. After being further crushed in the fine crushing hopper 2, the rock particles slide down the inclined inner wall of the conical hopper 3. The stepper motor 6 is started, and its output shaft rotates in the middle of the collection hopper 48, simultaneously driving the grinding wheel assembly 43 and the pusher plate 46 to rotate. The vertical cutter 431 performs circular motion inside the lower end pipe of the conical hopper 3. The horizontal protrusions of the vertical cutter 431 cooperate with multiple sets of vertically distributed side ridges 471 on the inner wall of the column hopper 47. A small gap exists between the protrusions and the side ridges 471, further impacting and crushing the falling particles. The crushing process involves a horizontal cutter 432 rotating on the upper side of the orifice plate 44. Both cutters and the horizontal cutter 432 are made of tungsten carbide alloy, which is highly wear-resistant and impact-resistant. Together, they grind rock particles into sand. Particles of the required size fall from the orifice plate 44 into the collection bin 48, while particles of the required size continue to be crushed until they fall into the collection bin 48, ensuring the uniformity of the sand particle size. Meanwhile, the rotating pusher plate 46 pushes the falling sand into the discharge port 45 for collection and storage. In small-batch production, this equipment realizes multiple steps in the dry sand making process, including medium crushing, sand making, and screening, without the need for multiple pieces of equipment, and can also make sand and ensure the quality of sand.

[0025] Example 2: Figure 1 - Figure 4 As shown, the feeding assembly includes a vertical rod 41 and spiral fan blades 42. The vertical rod 41 is vertically fixedly installed in the middle of the cross cutter 432. The upper end of the vertical rod 41 is rotatably connected to the upper side of the conical chamber 3. Multiple sets of spiral fan blades 42 are fixedly connected to the outer ring surface of the vertical rod 41. The spiral fan blades 42 are located inside the conical chamber 3.

[0026] The overall effect of this embodiment is that when the stepper motor 6 rotates, the grinding assembly 43 drives the upright 41 to rotate inside the conical chamber 3. The spiral fan blades 42 rotate spirally under the drive of the upright 41. The spiral fan blades 42 are designed according to the internal dimensions and installation position of the conical chamber 3. Multiple sets of spiral fan blades 42 rotate to convey the crushed rock particles downwards. The crushing efficiency of the fine crushing chamber 2 is faster than that of the grinding assembly 43. As the rock particles are continuously input, a certain amount of particles will accumulate inside the conical chamber 3. The pusher assembly is used to prevent the particles from clogging in the conical chamber 3 and to apply a downward force to the particles, thereby improving the conveying and crushing efficiency.

[0027] The operating method and working principle of this device are as follows: Coarsely crushed rock particles are conveyed to the feed hopper 1. After being further crushed in the fine crushing hopper 2, the rock particles slide down the inclined inner wall of the conical hopper 3. The stepper motor 6 is started, and its output shaft rotates in the middle of the collection hopper 48, simultaneously driving the grinding assembly 43 and the push plate 46 to rotate. The grinding assembly 43 then drives the upright rod 41 to rotate inside the conical hopper 3. The spiral fan blades 42 rotate spirally under the drive of the upright rod 41, conveying the further crushed rock particles downwards. The vertical cutter 431... The vertical cutter 431 moves in a circular motion inside the lower end pipe of the conical bin 3. The horizontal protrusion of the vertical cutter 431 cooperates with the multiple sets of vertically distributed side ridges 471 on the inner wall of the column bin 47. There is a small gap between the protrusion and the side ridges 471, which further impacts and crushes the falling particles. The horizontal cutter 432 rotates on the upper side of the orifice plate 44. Both are made of tungsten carbide alloy, which has extremely high wear resistance and impact resistance. Under the combined action of the two, the rock particles are ground into sand, which falls from the orifice plate 44 into the collection bin 48. The rotating pusher plate 46 pushes the falling sand into the discharge port 45 for collection and storage.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
