Description

Technical Field

[0001] The present invention belongs to the technical field of sand making machines, and in particular, relates to a composite sand making machine and a shaping system. Background Art

[0002] In the field of modern construction and mining, the demand for mechanical sand making and aggregate shaping is increasing, especially in terms of improving production efficiency, finished product quality, energy conservation and emission reduction, and ease of operation. Traditional sand making machinery usually cannot meet these needs at the same time, and there are problems such as uneven finished product particle size, high energy consumption, frequent replacement of wearing parts, and low degree of automation. Therefore, it is particularly important to develop a composite sand making machine and shaping system that integrates efficient sand making, precise shaping, energy conservation and environmental protection, and intelligent control.

[0003] The Chinese patent with the authorization announcement number CN215917590U discloses a stone shaping device for sand making. By setting a partition, a crushing roller, crushing teeth and a crushing plate, the device has the function of pre-crushing large stones. The stones are fed into the device body through the feed port, and the small stones fall into the stone shaping mechanism through the gap between the partitions. The large stones slide into the crushing plate through the top of the partition. The crushing motor drives the rotation of the crushing roller through the transmission rod, and the large pieces of materials are initially squeezed and crushed between the crushing plate and the crushing roller. The stone is crushed and then falls into the material shaping mechanism, which improves the efficiency of stone shaping and sand making. By setting up a filter, a vibrator, a spring and an exhaust fan for use, the device body can filter and collect stone powder. After passing through the stone shaping mechanism, the stone will fall to the upper end of the filter. The vibrator drives the filter to vibrate on the spring, so that the stone powder in the sand is filtered through the filter, and the sand flows out through the discharge port. The exhaust fan draws internal air to extract and collect powder and dust to prevent dust from scattering, improve the working environment, and also improve the quality of sand making.

[0004] However, the technical solution still has at least the following defects: in the technical solution, the stones that are still unqualified after shaping are not screened, and the stones after one shaping are mixed together, resulting in a lower overall qualified rate. At the same time, the device cannot adjust the particle size of the stones after shaping, and the scope of application is small. In view of this, the present invention is proposed.

DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0038] Example 1

[0039] like Figure 1 to Figure 2 As shown, the present invention discloses a composite sand making machine, including a sand making machine body 100. A heat dissipation mechanism is arranged on the side of the sand making machine body 100. The heat dissipation mechanism includes an air cooling component and an electric cooling component.

In this setting, the fan 102 inhales air through the air inlet port 107, and mixes the cold air and delivers it to the air inlet pipe 109, and the air inlet pipe 109 is connected to the sand making machine body 100, so that the cold air can cool the sand making machine body 100.

[0041] like Figure 1 to Figure 2 As shown, further, the electric cooling assembly includes a cooling plate 106, a frame is installed on the outside of the cooling plate 106, and one end of the frame is connected to the air inlet box 105;

[0042] An air outlet pipe 108 is installed on the top of the frame, one end of which is connected to the sand making machine body 100 and forms a passage with the air inlet pipe 109. In this configuration, the cooling plate 106 is used to produce cold air, wherein one side of the cooling plate 106 generates cold air, and the other side generates hot air through heat exchange, and the hot air is blown out through the air outlet pipe 108 to dissipate the hot air, so as to prevent the temperature on one side of the cooling plate 106 from being too high.

[0043] Example 2

[0044] like Figures 1 to 10As shown, the present invention also discloses a shaping system, including a composite sand making machine and a shaping chamber 300. The shaping chamber 300 is located at the bottom of the sand making machine body 100. A material throwing mechanism is arranged inside the shaping chamber 300. The material throwing mechanism includes a feed pipe 200. A branch pipe 201 is installed at the bottom of the feed pipe 200. A branch sleeve 202 is movably sleeved on the outer side of the branch pipe 201. The quartz sand in the feed pipe 200 is thrown toward the inner wall of the shaping chamber 300 through the high-speed rotation of the branch pipe 201 and the branch sleeve 202.

[0045] like Figure 4 , Figure 5 , Figure 7 As shown, in a specific embodiment, an adjustment mechanism is provided between the sub-sleeve 202 and the bottom of the sub-tube 201, and the adjustment mechanism includes a first pull rod 205 and a second pull rod 206, the first pull rod 205 is rotatably connected to the sub-sleeve 202, the second pull rod 206 is rotatably connected to the feed pipe 200, and the first pull rod 205 is rotatably connected to the second pull rod 206;

[0046] The adjustment mechanism also includes a reset assembly, which includes a first telescopic rod 203, the two ends of which are respectively fixedly connected to the branch tube 201 and the branch sleeve 202, and a first spring 204 is movably sleeved on the outer side of the first telescopic rod 203. In this configuration, the contraction or extension of the branch sleeve 202 and the branch tube 201 is controlled by folding or unfolding the first pull rod 205 and the second pull rod 206, and the first spring 204 is used to provide elastic force along the axial direction of the branch tube 201 to prevent the first pull rod 205 and the second pull rod 206 from being over-folded and then unfolded, resulting in insufficient force along the axial direction of the branch tube 201.

[0047] like Figure 5 , Figure 6 As shown, further, the adjustment mechanism also includes a pushing device, which includes an oil cylinder 210, an oil cylinder frame 211 is installed on the outside of the oil cylinder 210, the oil cylinder frame 211 is installed on the top of the shaping chamber 300, a second bearing 212 is installed between the oil cylinder frame 211 and the feed pipe 200, a fixing member 209 is installed at the output end of the oil cylinder 210, a first bearing 208 is installed at the bottom of the fixing member 209, the first bearing 208 is movably sleeved on the feed pipe 200, a support member 207 is installed at the bottom of the first bearing 208, and a connecting rod on the side of the support member 207 is rotatably connected to the connection between the first pull rod 205 and the second pull rod 206. In this setting, the oil cylinder 210 drives the support member 207 to move through the fixing member 209, thereby controlling the folding or unfolding of the first pull rod 205 and the second pull rod 206, and the friction between the adjustment mechanism and the feed pipe 200 is effectively reduced through the connection between the first bearing 208 and the second bearing 212.

[0048] like Figure 8 , Fig. 9As shown, further, a shell 301 is fixedly installed at the bottom of the shaping chamber 300, a base frame 303 is fixedly installed at the bottom of the shell 301, an inner shell 302 is fixedly installed at the top of the base frame 303, the top of the inner shell 302 is aligned with the top of the sub-casing 202, and a screening mechanism is provided between the shell 301 and the inner shell 302, the screening mechanism includes a screen 305, the screen 305 is slidably connected between the shell 301 and the inner shell 302, and the screening mechanism screens the quartz sand through the screen 305. In this setting, the closed ring formed by the shell 301 and the inner shell 302 effectively prevents the quartz sand from escaping. During screening, qualified quartz sand will pass through the sieve holes of the screen 305 and fall onto the guide plate 304, while unqualified quartz sand will remain on the screen 305.

[0049] Example 3

[0050] like Figure 8-Figure 10 As shown, in a specific embodiment, a vibration mechanism is provided at the bottom of the material throwing mechanism, and the vibration mechanism includes a guide ring 309, and a plane section 310 and an inclined section 311 are provided on the top of the guide ring 309. The vibration mechanism also includes a mounting frame 312, and the top of the mounting frame 312 is fixedly installed on the bottom of the branch pipe 201, and a roller 313 is rotatably installed on the end of the mounting frame 312, and the roller 313 cooperates with the guide ring 309. In the present configuration, the mounting frame 312 drives the roller 313 to rotate during its rotation, and the roller 313 presses down the guide ring 309 through the inclined surface section 311. When the roller 313 and the inclined surface section 311 are offset, the guide ring 309 is reset by the second spring 308, and the high-speed vibration of the guide ring 309 is achieved in this reciprocating manner. The guide ring 309 drives the screen 305 to vibrate at a high speed through the bracket 306, and the shaped quartz sand grains fall on the screen 305, and are vibrated by the high-speed vibration of the screen 305, and when they reach the height of the branch pipe 201, they are hit by the quartz sand grains thrown out by the branch pipe 201, and the quartz sand grains are shaped again by the stone-on-stone effect.

[0051] like Figure 8 , Fig. 9 As shown, further, a bracket 306 is installed on the outside of the guide ring 309, the top of the bracket 306 is fixedly installed on the bottom of the screen 305, one end of the bracket 306 movably penetrates the housing 301 and extends to the outside, a second telescopic rod 307 is fixedly installed on the bottom of one end of the bracket 306, the bottom of the second telescopic rod 307 is fixedly installed on the top of the base frame 303, and a second spring 308 is movably sleeved on the second telescopic rod 307. In this configuration, the second telescopic rod 307 is used to support the screen 305 while enabling it to maintain vertical movement, and the second spring 308 is used to provide power for the screen 305 to rise.

[0052] like Figure 4 , Fig.10As shown, further, a rotating shaft 314 is fixedly installed at the bottom of the mounting frame 312, a power device 315 is embedded and installed at the top of the base frame 303, the output end of the power device 315 is connected to the rotating shaft 314, the power device 315 is used to provide power and drive the mounting frame 312 and the branch pipe 201 to rotate, a guide plate 304 is installed at the bottom of the base frame 303, a feed funnel 101 is arranged at the top of the feed pipe 200, and the top of the feed funnel 101 is fixedly connected to the sand making machine body 100. In this setting, the power device 315 adopts a large torque energy-saving motor combined with a speed increaser, which effectively increases the speed while saving energy.

[0053] The implementation principle of the composite sand making machine and shaping system of the present embodiment is as follows: during the sand making process of the sand making machine body 100, the fan 102 and the refrigeration sheet 106 are continuously working. During the working process of the refrigeration sheet 106, the side close to the fan 102 continuously generates cold air, while the other side generates hot air. During the working process of the fan 102, air is continuously taken in through the air inlet 107. The taken-in air is mixed with the cold air and transported to the air inlet pipe 109 through the fan 102. The air enters the sand making machine body 100 through the air inlet pipe 109 for cooling. The cooled airflow is transported to one side of the refrigeration sheet 106 through the air outlet pipe 108, and the hot air generated by the refrigeration sheet 106 is blown away, thereby reducing the influence of the high temperature generated by the refrigeration sheet 106 on the refrigeration sheet 106.

[0054] The quartz sand particles produced by the sand making machine body 100 fall into the feed pipe 200 through the feed funnel 101, and the power device 315 is started. The power device 315 drives the mounting frame 312 and the branch pipe 201 to rotate at a high speed through the rotating shaft 314. During the high-speed rotation of the branch pipe 201, the quartz sand particles in the feed pipe 200 are thrown out, and the thrown out quartz sand particles hit the inner wall of the shaping chamber 300, thereby shaping the quartz sand particles;

[0055] The mounting frame 312 rotates and drives the roller 313 to rotate. The roller 313 presses the guide ring 309 through the inclined surface section 311. When the roller 313 and the inclined surface section 311 are offset, the guide ring 309 is reset by the second spring 308. In this way, the high-speed vibration of the guide ring 309 is realized. The guide ring 309 drives the screen 305 to vibrate at a high speed through the bracket 306. The shaped quartz sand particles fall on the screen 305. Under the high-speed vibration of the screen 305, qualified quartz sand particles will pass through the sieve holes of the screen 305 and fall to the guide plate 304, while unqualified quartz sand particles will be vibrated by the screen 305 and when they reach the height of the branch pipe 201, they are hit by the quartz sand particles thrown out by the branch pipe 201, and the quartz sand particles are reshaped again through the stone-on-stone effect.

[0056] During the shaping process, the quartz sand particles need to be subjected to different degrees of impact according to the different qualities of the quartz sand. The oil cylinder 210 is started. When the impact degree of the quartz sand particles needs to be increased, the oil cylinder 210 drives the support member 207 to move downward through the fixing member 209. The support member 207 moves downward while pressing down the first pull rod 205 and the second pull rod 206. At this time, the first pull rod 205 and the second pull rod 206 push the sub-sleeve 202 to move outward, and the extended end of the sub-sleeve 202 obtains a greater linear velocity, so that the quartz sand particles are thrown out at a greater speed. When the impact degree of the quartz sand particles needs to be reduced, the oil cylinder 210 drives the support member 207 to rise to fold the first pull rod 205 and the second pull rod 206. At this time, the sub-sleeve 202 moves inward, and its outer end obtains a smaller linear velocity, so that the speed at which the quartz sand particles are thrown out is reduced.

[0057] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
