Description

Technical Field

[0001] This application relates to the technical field of equipment for processing machine-made quartz sand, and in particular to a high-efficiency shaping device for machine-made quartz sand. Background Technology

[0002] With the deepening of environmental protection efforts in recent years, the extraction of river sand from waterways has become increasingly strict. Consequently, manufactured quartz sand is gradually being used in the construction industry to replace river sand. The production of manufactured quartz sand primarily uses granite, quartz sandstone, and rhyolite as raw materials, which are crushed and screened. Due to the characteristics of these materials, manufactured sand is characterized by sharp edges and numerous needle-like and flaky particles. Therefore, to improve the roundness of manufactured sand and remove internal impurities, it needs to undergo shaping. Existing manufactured sand shaping equipment often employs dry agitation, causing sand particles to collide and rub against each other in the mixing tank, thus removing their sharp edges. However, this type of processing equipment suffers from slow processing speed, poor particle uniformity, and the generation of a large number of over-crushed small particles, resulting in additional impurities. Furthermore, it requires an additional screening process, reducing production efficiency and resulting in poor shaping effects. Therefore, a high-efficiency shaping device is needed to solve these problems. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the purpose of this application is to provide a high-efficiency shaping device for machine-made quartz sand that offers high shaping efficiency, uniform roundness, stable shaping effect, and easy adjustment.

[0004] The above-mentioned objective of this application is achieved through the following technical solution:

[0005] A high-efficiency shaping device for machine-made quartz sand includes: a material cylinder, grinding rings, impellers, pressure plates, a lever, a support frame, a high-pressure air pump, a water pump, an inlet pipe, and a feed inlet. The upper end of the material cylinder is open. Several grinding rings are arranged and sequentially fixedly connected to the inner wall of the material cylinder. A ring array of baffles is fixedly arranged in the gaps between adjacent grinding rings. A rotating shaft is rotatably connected to the middle of the material cylinder. The impellers are vertically and equidistantly fixedly connected to the outer surface of the rotating shaft. The pressure plates are fixedly connected at intervals to the corresponding outer surfaces of the rotating shaft between the impellers. An annular guide groove is formed on the inner wall of the lower end of the material cylinder. One end of the lever is fixedly connected to the surface of the rotating shaft near the lower end. The moving rod bends downward in an arc shape, and the arc-shaped position of the moving rod is connected to the annular guide groove. The upper end of the material cylinder is connected to a top cover, and a drive module is connected to the top cover. The drive module drives the rotating shaft to rotate. Support frames are fixedly connected to the two sides of the lower part of the material cylinder, and a high-pressure air pump and a water pump are fixedly connected to the support frames on both sides, respectively. The output ends of the high-pressure air pump and the water pump are respectively connected to conduits. The other ends of the conduits extend tangentially into the lower end of the material cylinder on both sides. The input end of the water pump is connected to a liquid inlet pipe, which is connected to an external water source or water supply pipe. The feed port is connected to the upper end of one side of the top cover.

[0006] Optionally, the drive module includes a speed-regulating motor, a transmission wheel, and a transmission belt. The speed-regulating motor is fixedly connected to the surface of one side of the upper cover. The end of the output shaft of the speed-regulating motor is fixedly connected to a drive wheel. The transmission wheel is fixedly connected to the upper end of the rotating shaft. The two ends of the transmission belt are respectively connected to the drive wheel and the transmission wheel. The diameter of the drive wheel is smaller than the diameter of the transmission wheel.

[0007] Optionally, it also includes a bottom outlet and a top outlet. The bottom outlet is located on the outer surface of one side of the bottom of the barrel, and the top outlet is located on the side surface of the barrel near the upper end. Valves are respectively provided on the bottom outlet and the top outlet.

[0008] Optionally, it also includes a wear-resistant bushing, which is fixedly connected to the surface of the bottom of the barrel, and the lower end of the rotating shaft is connected to the wear-resistant bushing.

[0009] Optionally, it also includes a support base and connecting holes, wherein the support base is fixedly connected to the lower surface of the material cylinder, and the connecting holes are respectively provided on the surface of the support base near the outer side.

[0010] Optionally, it also includes lifting lugs, which are symmetrically and fixedly connected to the outer surface of the barrel.

[0011] Optionally, a protective cover is also included, which is fitted and connected to the corresponding upper cover surface of the drive module.

[0012] Optionally, it also includes support rods and connecting sleeves. The support rods are arranged in a circular oblique array. The lower end of each support rod is fixedly connected to the inner wall of the upper end of the material cylinder. The connecting sleeve is rotatably connected to the rotating shaft surface located at the corresponding position below the upper cover. The upper end of each support rod is fixedly connected to the outer surface of the connecting sleeve.

[0013] Compared with the prior art, this application has at least one of the following beneficial effects:

[0014] This high-efficiency shaping device for manufactured quartz sand achieves a wet grinding process for manufactured sand through a multi-layer structure. The structure, including the grinding ring, pressure plate, and baffle strip, enables more thorough friction of the sand-water mixture within the barrel. The friction intensity can be adjusted by the motor speed and the number of blades installed to meet different requirements for the roundness of manufactured sand.

[0015] Compared to dry friction shaping equipment, this high-efficiency quartz sand shaping device allows small particles to be carried away by the internal water flow during discharge and collected and classified directly at the bottom of the container during discharge, reducing the need for further screening and significantly improving production efficiency.

[0016] This high-efficiency quartz sand shaping device uses a bottom water pump to add water, which can flexibly adjust the liquid content during grinding and generate turbulence to avoid sedimentation. The air pump can inject air from the bottom during grinding, which further agitates the internal mixed liquid and fully turbulents during rotation, preventing sedimentation at the bottom, improving the uniformity of sand-water mixing, and further enhancing the grinding quality.

[0022] The present application will be further described in detail below with reference to the accompanying drawings.

[0023] To better understand the technical solutions presented in the embodiments of this application, the working principle of existing mechanical quartz sand shaping devices will first be introduced.

[0024] Existing manufactured sand shaping methods all use dry sand particles to collide with each other to remove sharp edges and improve roundness. However, this collision generates a large number of fine particles, which are unsuitable for construction sand and therefore need to be screened out. In addition, some grinding processes involve water spraying to reduce dust, which causes sand particles and small particles to adhere together, requiring further removal later. This makes the production process cumbersome, the grinding effect limited, and the sand quality poor. Therefore, it is necessary to improve the existing manufactured sand shaping equipment to solve these problems.

[0025] Please see Figures 1 to 4This application discloses a high-efficiency shaping device for machine-made quartz sand, comprising: a material cylinder 1, grinding rings 2, blades 5, pressure plates 6, actuating rods 8, a support frame 10, a high-pressure air pump 11, a water pump 13, an inlet pipe 14, and a feed inlet 15. The upper end of the material cylinder 1 is open. Several grinding rings 2 are arranged and fixedly connected to the inner wall of the material cylinder 1 in sequence. A turbulence strip 3 is fixedly arranged in a ring array in the gap between adjacent grinding rings 2. A rotating shaft 4 is rotatably connected to the middle of the material cylinder 1. Blades 5 are fixedly connected vertically at equal intervals to the outer surface of the rotating shaft 4. Pressure plates 6 are fixedly connected at intervals to the corresponding outer surfaces of the rotating shaft 4 between the blades 5. An annular guide groove 7 is provided on the inner wall of the lower end of the material cylinder 1. One end of the actuating rod 8 is fixedly connected to the surface of the rotating shaft 4 near the lower end. The lever 8 bends downward in an arc shape, and the arc shape of the lever 8 is connected to the annular guide groove 7. The upper end of the material cylinder 1 is connected to the upper cover 22, and the upper cover 22 is connected to the drive module 9. The drive module 9 drives the rotating shaft 4 to rotate. Support frames 10 are fixedly connected to the two sides of the lower position of the material cylinder 1, and high-pressure air pump 11 and water pump 13 are fixedly connected to the support frames 10 on both sides, respectively. The output ends of the high-pressure air pump 11 and water pump 13 are respectively connected to the conduit 12. The other end of the conduit 12 extends into the lower end of the two sides of the material cylinder 1 along the tangential direction. The input end of the water pump 13 is connected to the liquid inlet pipe 14, which is connected to an external water source or water supply pipe. The feed port 15 is connected to the upper end of one side of the upper cover 22.

[0026] Specifically, the upper cover 22 is bolted to the upper end of the material cylinder 1, facilitating the disassembly and replacement of internal components such as the grinding ring 2, thus reducing subsequent maintenance costs. After the drive module 9 is started, it drives the rotating shaft 4 to rotate at a certain speed. Depending on the type of quartz sand, one or more sets of blades 5 can be flexibly installed on the rotating shaft 4. Installing multiple sets of blades 5 increases the stirring force, preventing sand from settling at the bottom and providing sufficient stirring power. Under stirring, the water flow carries the sand upwards, allowing it to contact the surrounding grinding ring 2 structure, thus shaping the surface of the sand. However, because the water flow is spiral, the sand within the water flow cannot move flexibly... Friction is a factor, so turbulence strips 3 are installed to create turbulence in the rotating water flow, causing the internal sand particles to tumble and achieve sufficient friction. The number and angle of the turbulence strips 3 can be set according to requirements to enhance or reduce the turbulence effect. The pressure plate 6 can block the continuously rising liquid, reducing its upward force and preventing the rotating liquid surface from directly hitting the top of the material cylinder 1 during shaping. Working together with the turbulence strips 3, the internal rotation, grinding, and mixing effects are achieved, ensuring full contact between the molding sand and between the molding sand and the grinding ring 2, with a higher degree of uniform contact, achieving a stable grinding control effect. The support frame 10 can hold the water pump. 13 and the high-pressure air pump 11 are connected in a suitable position to supplement water or other liquid abrasives according to the feed rate from the feed inlet 15. Preferably, a high-pressure metering pump can be used instead. The high-pressure air pump 11 can generate pressurized gas, which is then tangentially introduced into the bottom of the barrel 1 through the conduit 12. The addition of high-pressure gas can make the turbulence in the barrel 1 more intense, making the mixing of particles and liquid more uniform. Under the stirring of the blades 5, the liquid and gas carry the molding sand particles to tumble and rub, greatly improving the grinding effect. At the same time, the bottom rush of high-pressure gas can further prevent the sand particles from settling, causing the sand particles at the bottom to turn upwards and better grind. The uniformly mixed sand and water inside the cylinder 1 is facilitated by an annular guide groove 7, which allows for the flow of the sand-water mixture at the bottom. Simultaneously, a grinding cover structure can be laid on its surface, increasing the grinding surface area. A lever 8 disperses the sand particles deposited in the annular guide groove 7, causing them to splash upwards and preventing accumulation at the bottom. This achieves a stable and uniform grinding effect, and the finished product flows out with the liquid. It can be used in a continuous feeding and discharging manner, or in an intermittent feeding and grinding manner. Compared to existing shaping equipment, efficiency is greatly improved, shaping quality is better, and the finished product can meet the construction needs of higher-standard buildings.

[0027] Please see Figure 2As another specific embodiment provided in the application, the drive module 9 includes a speed-regulating motor 91, a transmission wheel 93, and a transmission belt 94. The speed-regulating motor 91 is fixedly connected to the surface of one side of the upper cover 22. The end of the output shaft of the speed-regulating motor 91 is fixedly connected to the drive wheel 92. The transmission wheel 93 is fixedly connected to the upper end of the rotating shaft 4. The two ends of the transmission belt 94 are respectively connected to the drive wheel 92 and the transmission wheel 93. The diameter of the drive wheel 92 is smaller than the diameter of the transmission wheel 93.

[0028] Specifically, the speed-regulating motor 91 can generate different rotation speeds, which in turn drive the drive wheel 92 to rotate the transmission belt 94, which in turn drives the transmission wheel 93 to rotate, thus realizing the transmission of power. The two have different diameters, which can generate greater torque. Furthermore, by adjusting the motor speed, different grinding intensities can be achieved, thereby controlling the time to meet different roundness requirements.

[0029] Furthermore, in terms of control methods, traditional power distribution cabinets can be used for switching or microcontroller control.

[0030] Please see Figure 2 As another specific embodiment provided in the application, it also includes a bottom outlet 17 and a top outlet 18.

Valves are respectively provided on the bottom outlet 17 and the top outlet 18.

[0031] Specifically, the bottom outlet 17 is designed to meet the requirement of thorough bottom discharge, which facilitates internal cleaning. The top outlet 18 is designed for use in continuous production processes where materials need to be discharged from the top along with the liquid. Both outlets are equipped with valves, which can be replaced by solenoid valves for automatic control.

[0032] Please see Figure 4 As another specific embodiment provided in the application, it also includes a wear-resistant bushing 16, which is fixedly connected to the surface of the bottom of the material cylinder 1, and the lower end of the rotating shaft 4 is connected to the wear-resistant bushing 16.

[0033] Specifically, the wear-resistant bushing 16 reduces the friction between the rotating shaft 4 and the barrel 1, extending its service life.

[0034] Furthermore, in another embodiment, the wear-resistant bushing 16 can be set at an eccentric position at the bottom of the barrel 1, thereby adjusting the top of the rotating shaft 4 to make it vertical, while the rest of the structure remains unchanged. The setting of the eccentric rotating shaft 4 can generate a greater turbulence effect and achieve more intense shaping, which is suitable for grinding some particles that are too irregular or have too high hardness.

[0035] Please see Figure 3As another specific embodiment provided in the application, it also includes a support base 19 and a connection hole 191. The support base 19 is fixedly connected to the lower surface of the material cylinder 1, and the connection holes 191 are respectively provided on the surface of the support base 19 near the outer side.

[0036] Specifically, the support base 19 can stably support the material cylinder 1, allowing it to be placed in different working positions. The connection hole 191 facilitates connection and fixation, improving flexibility.

[0037] Please see Figure 1 As another specific embodiment provided in the application, it also includes a lifting lug 20, which is symmetrically and fixedly connected to the outer surface of the material cylinder 1.

[0038] Specifically, the lifting lug 20 facilitates the handling and use of the material cylinder 1, meeting the actual transfer needs of the scenario.

[0039] Please see Figure 1 As another specific embodiment provided in the application, it also includes a protective cover 21, which is connected to the surface of the upper cover 22 corresponding to the drive module 9.

[0040] Specifically, the protective cover 21 can cover the components inside the drive module 9, which can prevent injury to personnel and prevent external dust corrosion, thus extending the service life.

[0041] Please see Figure 3 As another specific embodiment provided in the application, it also includes support rods 23 and connecting sleeves 24. The support rods 23 are arranged in a circular oblique array. The lower end of the support rods 23 is fixedly connected to the inner wall of the upper end of the material cylinder 1. The connecting sleeves 24 are rotatably connected to the surface of the rotating shaft 4 located at the corresponding position below the upper cover 22. The upper ends of each support rod 23 are fixedly connected to the outer surface of the connecting sleeves 24.

[0042] Specifically, the support rod 23 and the connecting sleeve 24 can support the rotation of the rotating shaft 4, making it more stable during rotation, reducing axial runout, and maintaining stable operation of the equipment.

[0043] 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.
