[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the utility model. Apparently, the described embodiments are only a part of the embodiments of the utility model, rather than all of the embodiments.

[0023] All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the utility model without creative efforts shall fall within the protection scope of the utility model.

[0024] Refer to Figure 1 As shown, in some embodiments, a continuous automated production line of cristobalite is provided, and the system mainly includes a walking track 100, a high-temperature tunnel kiln 200, a carrier trolley 300, an intelligent feeding bin 400, an intelligent discharging bin 500, a car lifter 600, and a ferry truck 700. There are several carrier trolleys 300 for loading materials.

[0025] There are four top carriages 600, which are respectively installed at the four corner positions of the walking track 100 to push the load-carrying trolley 300 forward. The first top carriage 601 and the third top carriage 603 adopt pushing devices, and the second top carriage 602 and the fourth top carriage 604 can adopt push-pull devices; there are two transfer vehicles 700, which are respectively installed on the two short guide rails of the walking track 100 to switch the load-carrying trolley 300 back and forth between the two long tracks.

[0026] Specifically, the walking track 100 is arranged as a rectangular closed loop as a whole, which is formed by connecting the first long track 101, the first short track 102, the second long track 103 and the second short track 104 end to end, and each track adopts a double-track light rail structure design.

[0027] In terms of the specific structural layout, the first long track 101 and the second long track 103 are arranged in parallel at intervals front and back. Along the forward direction of the system operation on the outer peripheral side of the first long track 101, the intelligent material receiving bin 500 and the intelligent feeding bin 400 are successively arranged. The second long track 103 runs through the high-temperature tunnel kiln 200. The high-temperature tunnel kiln 200 adopts an electrically heated high-temperature kiln and has a waste heat utilization structure, which is highly energy-efficient. The automatic feeding and automatic material receiving processes of each load-carrying trolley 300 are realized through the intelligent material receiving bin 500 and the intelligent feeding bin 400.

[0028] The first short track 102 and the second short track 104 are arranged in parallel at intervals left and right. The corresponding transfer vehicles 700 are respectively arranged on the first short track 102 and the second short track 104 at the left and right ends, and the corresponding top carriages 600 are respectively arranged at the tail ends of each track. The operation and circulation of each load-carrying trolley 300 are realized through each top carriage 600 and the transfer vehicle 700.

[0029] To achieve the continuous and automated production of this production system, there are several load-carrying trolleys 300, which are connected end to end and cover the first long track 101 and the second long track 103. That is, each load-carrying trolley 300 is successively abutted and connected on the first long track 101 and the second long track 103. All the load-carrying trolleys 300 on a single long track can be synchronously pushed forward through the corresponding top carriage 600.

[0030] The main operation mode of each load-carrying trolley 300 is as follows. Driven by each car pusher 600, the load-carrying trolley 300 automatically loads quartz sand raw materials at the position of the intelligent feeding bin 400. Each load-carrying trolley 300 is pushed and operated by the car pusher 600 at the end. The one-time pushing distance is the net length of one load-carrying trolley 300. After an interval of several times, it is pushed again, and it repeats the action at a certain frequency in this way. Then, the load-carrying trolley 300 after loading quartz sand raw materials is pushed to the high-temperature tunnel kiln 200 for preheating, high-temperature calcination and forced cooling treatment. Then, the load-carrying trolley 300 coming out of the high-temperature tunnel kiln 200 is pushed to the position of the intelligent receiving bin 500 for automatic unloading.

[0031] It should be noted that the back-and-forth switching of each load-carrying trolley 300 at the connection between the long track and the short track is realized through the mutual cooperation of the ferry truck 700 and the car pusher 600.

[0032] As one of the preferred embodiments, as Figure 1 shown, to ensure the smoothness and stability of the back-and-forth transfer switching of each load-carrying trolley 300 at the connection between the long track and the short track, the first long track 101 and the second long track 103 are arranged in parallel front and back, and the first short track 102 and the second short track 104 are arranged in parallel left and right, and each long track and each short track are arranged vertically, forming a rectangular closed-loop layout.

[0033] This rectangular closed-loop structure design of the walking track 100 enables the ferry truck 700 to accurately connect the ends of the first long track 101 and the second long track 103 when reciprocating on the first short track 102 and the second short track 104, so as to facilitate the transfer of the load-carrying trolley 300 between the long track and the short track.

[0034] It should be noted that to realize the horizontal connection between the ferry truck 700 on the short track and the end of the long track 103, it is required that the first short track 102 and the second short track 104 are arranged in a sunken manner relative to the long track, and the ferry truck 700 is respectively placed on the sunken first short track 102 and the second short track 104. After placing the ferry truck 700, the ferry truck 700 can be connected to the end of the long track.

[0035] The trolley at the end of the first long track 101 or the second long track 103 is transported onto the ferry 700 under the push of the corresponding first car lifter 601 and the third car lifter 603; the ferry 700 transports the load-carrying trolley 300 on it to the end of another long track under the push of the second car lifter 602 and the fourth car lifter 604. The ferry 700 can raise the horizontal height of the load-carrying trolley 300 on it to be consistent with the horizontal height of the load-carrying trolleys 300 on the first long track 101 and the second long track 103.

[0036] As one of the preferred embodiments, to cooperate with the intelligent feeding bin and the intelligent receiving bin to achieve automatic feeding and receiving, a material carrier is provided on each of the load-carrying trolleys 300, and the material carrier runs and shuttles on the track along with the load-carrying trolley 300. The material carrier is hinged and installed on the load-carrying trolley 300 in a tipping bucket structure for easy tipping and discharging; or the material carrier is directly placed on the load-carrying trolley 300 in a non-fixed connection manner for easy replacement and maintenance of the load-carrying trolley 300 and the material carrier.

[0037] In some embodiments, refer to Figure 1 As shown, both the intelligent feeding bin 400 and the intelligent receiving bin 500 are installed above the first long track 101. The quartz sand raw material is automatically added into the lower load-carrying trolley 300 by the feeding nozzle on the intelligent feeding bin 400, and the quartz sand finished product in the lower load-carrying trolley 300 is sucked out and stored by the suction nozzle on the intelligent receiving bin 500.

[0038] Specifically, in the loading area 1011, the intelligent feeding bin 400 uses visual sensing technology to control the left-right, front-back movement of the feeding nozzle and fill the empty material carrier with raw material quartz sand. In the unloading area 1012, the intelligent receiving bin 500 uses visual sensing technology to control the up-down, left-right, front-back movement of the suction nozzle and suck out all the finished product cubic quartz sand in the material carrier for storage.

[0039] Of course, as an alternative technical solution, the intelligent feeding bin 400 can also be installed above the first long track 101, and the intelligent receiving bin 500 can be installed at the lower side of the first long track 101. The feeding method of the intelligent feeding bin 400 is as above, and the receiving method of the intelligent receiving bin 500 can use the intelligent robotic arm equipped on it to automatically turn over the tipping bucket type material carrier on the load-carrying trolley 300 to pour the quartz sand finished product in the material carrier into the intelligent receiving bin 500 at the lower side position, and the automatic receiving process can also be realized.

[0040] As one of the preferred embodiments, refer to Figure 1As shown in the figure, the intelligent feeding bin 400 and the intelligent receiving bin 500 are respectively installed in the loading area 1011 and the unloading area 1012 at the head end of the first long track 101. The loading area 1011 is located downstream of the unloading area 1012. The loading area 1011 and the unloading area 1012 only occupy at most one-third of the length of the first long track 101, so as to form a natural air cooling area 1013 with a relatively large transfer travel at the tail end and the middle of the first long track 101, so as to make full use of the relatively long transfer travel range to fully realize the natural air cooling of the quartz sand finished product.

[0041] As Figure 1 shown in the figure, in these embodiments, to realize the continuous production of cristobalite, it is required that the carrier trolley and the material carrier circulate and operate within the closed-loop walking track 100. For this reason, the primary pushing distance of the first car pusher 601 arranged at the tail end of the first long track 101 and the third car pusher 603 arranged at the tail end of the second long track 103 is the net length of one carrier trolley 300.

[0042] The push rods at the front ends of the first car pusher 601 and the third car pusher 603 are connected to the carrier trolley 300 in a non-fixed abutting connection manner. After the push rods at the front ends of the first car pusher 601 and the third car pusher 603 push the carrier trolley 300 by a net length of one carrier trolley 300, they automatically retract to prepare for the pushing of the next carrier trolley 300.

[0043] Correspondingly, to ensure consistency with the pushing speed of the carrier trolley 300 on the first long track 101 and the second long track 103, it is required that the primary pushing distance of the second car pusher 602 arranged at the tail end of the first short track 102 and the fourth car pusher 604 arranged at the tail end of the second short track 104 is the net length of the short track, that is, when the second car pusher 602 and the fourth car pusher 604 push the carrier trolley 300 once, the carrier trolley 300 can be pushed from the front end to the tail end of the first short track 102 or the second short track 104, realizing the precise connection and switching of the ferry car 700 between the first long track 101 and the second long track 103.

[0044] And to realize the continuous cyclic use of the ferry car 700, the push rod at the front end of the car pusher 600 is fixedly connected to the ferry car 700. There are two ferry cars 700, including the first ferry car 701 slidably installed on the first short track 102 and the second ferry car 702 slidably installed on the second short track 104. After the push rods at the front ends of the second car pusher 602 and the fourth car pusher 604 push the carrier trolley 300 on the ferry car 700 by a net length of one short track, they synchronously drive the ferry car 700 to automatically retract to prepare for the pushing of the next carrier trolley 300.

[0045] As a preferred embodiment, to further improve the accuracy and stability of the transfer of the carrier trolley 300 between the ferry vehicle 700 and the first long track 101 and the second long track 103, a ferry track having the same specifications as and parallel to the first long track 101 and the second long track 103 is provided on the ferry vehicle 700.

[0046] The inner end of the ferry track is horizontally connected to the ends of the first long track 101 and the second long track 103, and the other end is closed. The setting of this ferry track can effectively prevent the carrier trolley 300 from shifting on the ferry vehicle 700, thereby overcoming the problems that the carrier trolley 300 is prone to slipping on the ferry vehicle 700 and cannot be aligned with the corresponding long track.

[0047] As an alternative technical solution, the driving mode of the ferry vehicle 700 is not limited to the push-pull machine. According to needs, the ferry vehicle 700 can also run with its own power.

[0048] Based on the above feasible embodiments of the continuous automated production line of cristobalite, as Figure 2 shown, a running method using the above production system is provided. The running method mainly includes the following steps:

At this time, there is a trolley on the first ferry vehicle 701 and no trolley on the second ferry vehicle 702. The material carrier on the trolley at the intelligent loading bin 400 is empty, and the material carrier on the trolley at the intelligent unloading bin 500 is full; the first car pusher 601 makes a retracting action, and the push rod retracts;

At this time, there is no trolley on the first ferry car 701 and there is a trolley on the second ferry car 702. The third top car body 603 makes a pulling action and the push rod retracts;

[0055] Step 6, the second top car body 602 makes a pulling action to pull the first ferry car 701 from the tail end of the second long track 103 along the first short track 102 to the head end of the first long track 101; the fourth top car body 604 makes a pushing action to push the second ferry car 702 from the head end of the second long track 103 along the second short track 104 to the tail end of the first long track 101; these two actions can be carried out simultaneously or sequentially;
