Description

Technical Field

[0001] This application relates to the field of manufactured sand shaping technology, and in particular to an adjustable quartz sand shaping machine. Background Technology

[0002] In recent years, with the increasing demand for sand and gravel aggregates in the construction industry, quartz sand shaping is essentially the process of shaping irregular finished sand particles. If the finished quartz sand particles meet the requirements, are cubic in shape, and have no tension or cracks, then shaping is unnecessary. Conversely, if the finished product has excessively sharp edges and corners and a high content of needle-like and flaky materials, it cannot be used in most engineering fields without shaping, and it will be difficult to sell.

[0003] There are two main methods for shaping quartz sand: dry grinding and wet grinding. While dry grinding can shape quartz sand particles, it generates a lot of dust during the process. Therefore, wet grinding is currently the primary method for shaping quartz sand particles. In wet grinding, the raw quartz sand to be shaped and water are directly added into the shaping cylinder. A mixing mechanism and a bottom aeration mechanism are used to stir and mix the quartz sand and water. During the stirring and mixing process, the quartz sand particles collide with each other and with the wear-resistant sleeve, thus shaping the quartz sand particles. The shaped quartz sand particles and water are discharged into a sieve frame with corresponding mesh openings so that the shaped quartz sand particles are retained by the sieve frame. The wastewater from the shaping process falls through the sieve into the wastewater collection tank at the bottom.

[0004] While existing wet grinding quartz sand shaping machines can shape quartz sand particles, the cleaning of the shaped quartz sand from the screen after shaping is mainly done manually, resulting in low discharge efficiency and high labor intensity. Furthermore, after shaping the quartz sand raw material, the worn screen needs to be replaced to efficiently retain the shaped quartz sand. However, existing wet grinding quartz sand shaping machines primarily replace the screen by repeatedly disassembling and removing bolts, a cumbersome process that hinders efficient adjustment and use of the machine. Summary of the Invention

[0023] The present application will be further described in detail below with reference to the accompanying drawings.

[0024] To better understand the technical solutions presented in the embodiments of this application, the working principle of the existing wet grinding quartz sand shaping machine will be introduced first.

[0025] Existing wet grinding quartz sand shaping machines directly add the quartz sand raw material to be shaped and water into the shaping cylinder during wet grinding and shaping. The mixing mechanism and bottom aeration mechanism are used to stir and mix the quartz sand and water. During the stirring and mixing process, the quartz sand particles collide with each other, and at the same time, the quartz sand particles collide with the wear-resistant sleeve, thereby achieving the shaping of the quartz sand particles. The shaped quartz sand particles and water are discharged into the screen frame with corresponding mesh size so that the shaped quartz sand particles can be intercepted under the action of the screen frame. The wastewater after shaping falls through the screen into the wastewater collection tank at the bottom.

[0026] Please see Figures 1-4This application discloses an adjustable quartz sand shaping machine, including a support platform 2. A shaping cylinder 5 is installed at the top center of the support platform 2. A sealing mechanism 10 is installed at the discharge port at the bottom end of the shaping cylinder 5 on the support platform 2. The sealing mechanism 10 includes a sealing plate 101, a sliding cavity 102, a slider 103, a two-way lead screw 104, a sliding groove 105, and a motor 106. A collection frame 3 is installed on the support platform 2 below the sealing mechanism 10. A discharge mechanism 8 is installed inside the collection frame 3 for discharging materials. Mechanism 8 includes an electric telescopic rod 81, a scraper 82, a connecting rod 83, and a baffle 84. A downwardly inclined guide plate 12 is also installed on the discharge side of the collection frame 3. An automatic screen changing mechanism 11 is installed on the two symmetrical side walls of the collection frame 3. The automatic screen changing mechanism 11 includes a guide cylinder 111, a winding drum 112, a motor 113, a filter belt 114, an unwinding drum 115, and a motor 116. An open-top sewage collection box 4 is also installed on the support platform 2 directly below the collection frame 3.

[0027] Specifically, when intercepting the shaped quartz sand particles, the motors 113 and 116 are synchronized under the action of the external synchronous control mechanism. After the motor 113 starts, it drives the winding drum 112 to rotate, so as to wind up the filter belt 114. After the motor 116 starts, it drives the unwinding drum 115 to rotate, so as to unwind the filter belt 114. During the continuous unwinding and winding process of the filter belt 114, the unworn part of the filter belt 114 is located inside the collection frame 3, while the worn part of the filter belt 114 is wrapped up, so as to intercept different types of shaped quartz sand particles. The intercepted quartz sand is finally discharged at the guide plate 12 when the electric telescopic rod 81 drives the scraper 82 to move, so as to facilitate the discharge of the shaped quartz sand particles.

[0028] Please see Figures 2-3 The sliding cavity 102 is opened on both sides of the hollow part of the support platform 2 directly opposite the discharge port of the forming cylinder 5, and the sliding groove 105 is opened on one side of the top of the support platform 2. The bidirectional screw 104 is rotatably installed in the middle of the sliding groove 105.

[0029] In one implementation, the sliding cavity 102 is mainly used to house the sealing plate 101, and the sliding groove 105 is mainly used to guide the sliding of the slider 103. The sliding cavity 102 and the sliding groove 105 are connected.

[0030] Please see Figure 1 and Figure 3 There are two sliders 103, which are symmetrically mounted on the bidirectional lead screw 104. Each slider 103 is connected to a sealing plate 101, which is slidably mounted in the slide cavity 102. The motor 106 is connected to the power input end of the bidirectional lead screw 104.

[0031] In one implementation, after the motor 106 drives the bidirectional lead screw 104 to rotate, the two sliders 103 will move away from each other under the action of the threaded transmission, so that the sealing plate 101 can be moved away synchronously under the action of the sliders 103, ensuring that the discharge port of the shaping cylinder 5 is connected to the lower collection frame 3, so as to facilitate the convenient discharge of the shaped quartz sand and water.

[0032] Please see Figures 1-2 The electric telescopic rod 81 is installed on the collection frame 3 on the side opposite to the guide plate 12. The scraper 82 is installed on the telescopic part of the electric telescopic rod 81. The connecting rod 83 is installed on the side wall of the scraper 82 facing away from the electric telescopic rod 81 by bolts. The baffle 84 is installed on the end of the connecting rod 83 facing away from the scraper 82. The bottom end of the scraper 82 contacts the upper side of the filter belt 114. The baffle 84 slides with the collection frame 3.

[0033] In one implementation, after the electric telescopic rod 81 drives the scraper 82 to move, the scraper 82 will push the shaped quartz sand particles located on the upper side of the filter belt 114 in the collection frame 3 onto the guide plate 12. At the same time as the scraper moves, the baffle 84 can be moved synchronously with the help of the connecting rod 83, so that the baffle 84 side of the collection frame 3 can be opened to facilitate the convenient fall of the pushed-out quartz sand particles.

[0034] Please see Figure 1 and Figure 4 The take-up drum 112 is rotatably mounted on the upper part of the outer side wall of the collection frame 3, and the unwind drum 115 is mounted on the upper part of the other side wall of the collection frame 3. Motor 3 113 is connected to the power input end of the take-up drum 112, and motor 4 116 is connected to the power input end of the unwind drum 115.

[0035] In one implementation, motor 3 113 is mainly used to drive the winding drum 112 to rotate, and motor 4 116 is mainly used to drive the unwinding drum 115 to rotate, so as to ensure that the unworn parts of the filter belt 114 can be easily replaced in the collection frame 3.

[0036] Please see Figure 4 Motor 3 113 and motor 4 116 are synchronous starting motors. A guide cylinder 111 is provided on the lower side of both the unwinding drum 115 and the winding drum 112. A filter screen belt 114 is wound together on the unwinding drum 115 and the winding drum 112. The filter screen belt 114 is in a taut state inside the collection frame 3. The contact parts between the bottom two sides of the collection frame 3 and the upper side of the filter screen belt 114 are scraping platform structures.

[0037] As one implementation method, the unworn part of the filter belt 114 is placed in the collection frame 3 by continuous movement, which can conveniently filter and retain the shaped quartz sand. The scraping platform structure on the collection frame 3 makes it easy to scrape off the residual quartz sand on the filter belt 114 when it is replaced, ensuring convenient winding of the filter belt 114.

[0038] Please see Figures 1-2 A mounting plate 6 is welded to the middle of the top of the shaping cylinder 5. A shaping mechanism 9 is installed on the shaping cylinder 5 and the mounting plate 6. The shaping mechanism 9 includes a motor 91, a wear-resistant sleeve 92, a mixing shaft 93, a diverter pipe 94, and an air pump 95. An anti-overflow mechanism 7 is also installed at the bottom of the mounting plate 6. The anti-overflow mechanism 7 includes a guide rod 71, a waterproof electric push rod 72, and a water baffle 73. A feeding hopper 1 is also installed on the upper part of one side wall of the shaping cylinder 5.

[0039] In one implementation method, after the quartz sand to be shaped and water are added into the shaping cylinder 5, the mixing shaft 93 is rotated under the action of the motor 91, which can stir and mix the quartz sand and water in the shaping cylinder 5. During the mixing process of the quartz sand and water in the clamping plate, collisions will occur between the quartz sand particles and between the quartz sand and the wear-resistant sleeve 92, thereby smoothing the edges and corners of the quartz sand particles and realizing the shaping of the quartz sand particles.

[0040] Please see Figures 1-2 Motor 91 is installed at the top center of mounting plate 6, mixing shaft 93 is installed at the power output end of motor 91, wear-resistant sleeve 92 is welded to the inner wall of shaping cylinder 5, air pump 95 is installed on one side of the top of support platform 2, and diversion pipe 94 is connected between air pump 95 and shaping cylinder 5. The air outlet direction of diversion pipe 94 is tangent to the inside of shaping cylinder 5.

[0041] As one implementation method, during the shaping process, air is blown into the shaping cylinder 5 by the air pump 95 and the diversion pipe 94. Under the action of the blown air, the turbulence in the shaping cylinder 5 is increased, while the sedimentation of quartz sand at the bottom of the shaping cylinder 5 is avoided, thus ensuring the shaping efficiency of quartz sand.

[0042] Please see Figures 1-2 The waterproof electric actuator 72 is installed on one side of the bottom end of the mounting plate 6. The water-blocking cover 73 is connected to the telescopic part of the waterproof electric actuator 72. The guide rod 71 is installed on the top of the water-blocking cover 73 on the opposite side of the waterproof electric actuator 72. The guide rod 71 passes through the mounting plate 6 and slides with the mounting plate 6.

[0043] As one implementation method, the waterproof electric actuator 72 moves the water-blocking cover 73 down to above the surface of the mixed liquid of quartz sand and quartz sand in the shaping cylinder 5, which can prevent water from splashing outward during the quartz sand shaping process.

[0044] The specific working principle is as follows: When shaping quartz sand, the shaping machine is first connected to an external power supply and control mechanism. The quartz sand particles to be shaped and water are added into the shaping cylinder 5 through the feeding hopper 1. Then, as the motor 91 drives the mixing shaft 93 to rotate, the quartz sand particles and water are stirred and mixed in the shaping cylinder 5. During the stirring and mixing process, collisions occur between the quartz sand particles and between the quartz sand and the wear-resistant sleeve 92, thereby smoothing the edges and corners of the quartz sand particles and achieving the desired shape. The shaping process involves blowing air into the shaping cylinder 5 via the air pump 95 and the diversion pipe 94 during the mixing of quartz sand particles. This increases the turbulence within the shaping cylinder 5, and the deposition of quartz sand at the bottom of the cylinder ensures efficient shaping. When retaining the shaped quartz sand particles, the external synchronous control mechanism synchronizes motors 113 and 116. Once motor 113 starts, it drives the winding drum 112 to rotate, thus facilitating filtration. The mesh belt 114 is wound up, and the motor 116, once started, drives the unwinding drum 115 to rotate, thereby unwinding the filter mesh belt 114. During the continuous unwinding and winding process of the filter mesh belt 114, the unworn parts of the filter mesh belt 114 are positioned inside the collection frame 3, while the worn parts of the filter mesh belt 114 are wrapped up to trap different types of shaped quartz sand particles. The trapped quartz sand is then removed as the electric telescopic rod 81 drives the scraper 82 to move, thus achieving the desired quartz sand particle size distribution. The particle guide plate 12 discharges the shaped quartz sand particles for convenient discharge. Under the action of this type of shaping machine, the shaped quartz sand particles are automatically discharged, resulting in higher discharge efficiency and less manual labor intensity. At the same time, the automatic screen changing mechanism 11 enables the unworn part of the filter screen belt 114 to move conveniently into the collection frame 3, so as to meet the high-efficiency interception requirements of the shaping machine for the shaped quartz sand particles and facilitate the efficient adjustment and use of the wet grinding quartz sand shaping machine.

[0045] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
