[0032] A transition frame 4 is arranged at one side of the calcining kiln 1 along the length direction of the calcining kiln 1, one end of the transition frame 4 is adjacent to the kiln tail of the calcining kiln 1, and a kiln-discharging self-moving trolley 3 moves between the kiln tail of the calcining kiln 1 and the end of the transition frame 4; the kiln-discharging self-moving trolley 3 reciprocates between the transition frame 4 and the kiln tail of the calcining kiln 1 along the length direction perpendicular to the calcining kiln 1, when the kiln-discharging self-moving trolley 3 moves to the calcining kiln 1, the track 13 on the kiln-discharging self-moving trolley 3 docks with the track 13 in the calcining kiln 1, so that the traction mechanism 12 pulls the material transport trolley 2 at the kiln tail in the calcining kiln 1 onto the kiln-discharging self-moving trolley 3; when the kiln-discharging self-moving trolley 3 moves to the transition frame 4, the track 13 on the kiln-discharging self-moving trolley 3 docks with the track 13 on the transition frame 4, so that the traction mechanism 12 pushes the material transport trolley 2 on the kiln-discharging self-moving trolley 3 onto the transition frame 4.

[0033] The traction mechanism 12 comprises a driving oil cylinder 12.1, a traction oil cylinder 12.2 and two guide rails 12.3 arranged in parallel with each other. The guide rails 12.3 are arranged in parallel with the corresponding rails 13 and are placed between the two corresponding rails 13. The two guide rails 12.3 are channel steels with notches arranged in parallel with each other. The guide rails 12.3 are fixed to the top surfaces of the corresponding kiln-discharging self-moving trolleys 3 and the top surfaces of the kiln-entering self-moving trolleys 10 through connecting rods.

The cylinder body of the driving oil cylinder 12.1 is hinged to the top surfaces of the corresponding kiln-discharging self-moving trolleys 3 and the top surfaces of the kiln-entering self-moving trolleys 10. The traction frame 12.4 is driven to reciprocate along the guide rails 12.3 by controlling the telescopic movement of the driving oil cylinder 12.1.

When the self-moving trolley 3 for discharging the kiln needs to push the material transport trolley 2 onto the transition frame 4, the traction cylinder 12.2 drives the traction block 12.7 to retract. During the process of the traction frame 12.4 being driven by the driving cylinder 12.1 to move toward the transition frame 4, the driving block 12.9 is clamped on the edge of the material transport trolley 2 until it is pushed onto the transition frame 4.

[0036] The kiln self-moving trolley 3 transfers the material transport trolley 2 to the transition frame 4 through the traction mechanism 12, and the material transport trolleys 2 on the transition frame 4 are fitted in sequence.

The material basin 15 below it is arranged by the material sorting machine 5 to facilitate the subsequent accurate clamping of the manipulator 6; in this embodiment, the crusher 7 uses the existing hammer crusher 7, and the manipulator 6 uses the model M-20iA. The manipulator 6 clamps the material basin 15 on the material transport trolley 2, and pours the material in it into the crusher 7 for crushing. After the material is poured, the material basin 15 is put back on the material transport trolley 2 by the manipulator 6.

[0037] The other end of the transition frame 4 is provided with a urea feeder 8 at the kiln head of the calcining kiln 1, and a transfer self-moving trolley 9 is moved between the urea feeder 8 and the other end of the transition frame 4; after the transition frame 4 is full of material transport trolleys 2, before the kiln self-moving trolley 3 pulls the material transport trolley 2 on one end of the transition frame 4, the transfer self-moving trolley 9 is controlled to move to the other end of the transition frame 4. At this time, the track 13 on the transfer self-moving trolley 9 is docked with the track 13 on the transition frame 4, and while the kiln self-moving trolley 3 pulls the material transport trolley 2 on one end of the transition frame 4, the material transport trolley 2 at the other end of the transition frame 4 is ejected onto the transfer self-moving trolley 9, and the transfer self-moving trolley 9 carries the material transport trolley 2 and moves it to the urea feeder 8, so that the urea feeder 8 can add urea raw materials into the material basin 15 above the material transport trolley 2, so as to facilitate the subsequent delivery into the calcining kiln 1 for calcination.

[0040] The connecting assembly 8.5 includes an upper pressing plate 8.5.1, a lower pressing plate 8.5.2 and a guide plate 8.5.3; the upper pressing plate 8.5.1 and the lower pressing plate 8.5.2 are provided with connecting holes 8.5.4 corresponding to each feeding tube assembly 8.6, and the connecting holes 8.5.4 are coaxially arranged with the corresponding through holes 8.4, and the feeding port of the top connecting pipe 8.6.3 of the feeding tube assembly 8.6 slides into the connecting hole 8.5.4 of the upper pressing plate 8.5.1 and is fixedly connected, and the discharging port of the bottom connecting pipe 8.6.3 of the feeding tube assembly 8.6 slides into the connecting hole 8.5.4 of the lower pressing plate 8.5.2 and is fixedly connected.

Through the guide plates 8.5.3, gaps are left between the feeding port of the top connecting pipe 8.6.3 of the down-feeding pipe assembly 8.6 and the top plate 8.2, and between the discharging port of the bottom connecting pipe 8.6.3 of the down-feeding pipe assembly 8.6 and the bottom plate 8.3.

[0041] A first plug plate 8.7 is slidably provided between the top feed port of each row of discharge tube assemblies 8.6 and the top plate 8.2, and a second plug plate 8.8 is slidably provided between the bottom discharge port of each row of discharge tube assemblies 8.6 and the bottom plate 8.3. The ends of each row of first plug plates 8.7 and the ends of each row of second plug plates 8.8 are connected by connecting beams 8.9 respectively; both sides of the first plug plate 8.7 and both sides of the second plug plate 8.8 are fitted with two corresponding adjacent guide plates 8.5.3, and slide under the guidance of the guide plates 8.5.3; discharge holes 8.10 corresponding to the feed port and discharge port of the discharge tube assemblies 8.6 are provided on the first plug plate 8.7 and the second plug plate 8.8; when the first plug plate 8.7 slides until all the discharge holes 8.10 thereon correspond to the top feed port of the discharge tube assemblies 8.6, the silo 8.1 is 3 can fall into the quantitative material pipe 8.6.1 and the connecting pipe 8.6.3 through the discharge hole 8.10; when the discharge hole 8.10 on the first plug plate 8.7 is staggered with the top feed port of the discharge pipe assembly 8.6, the raw material in the silo 8.13 can be blocked from flowing downward; similarly, by sliding the second plug plate 8.8, the discharge and closing of the bottom connecting pipe 8.6.3 of the discharge pipe assembly 8.6 can be achieved; a discharge pipe 8.14 extending downward is fixed at the through hole 8.4 on the bottom plate 8.3, and a transfer self-moving trolley 9 carrying a material transport trolley 2 is moved below the discharge pipe 8.14. When the discharge hole 8.10 on the second plug plate 8.8 corresponds to the pipe opening of the connecting pipe 8.6.3, the raw material in the discharge pipe assembly 8.6 falls into the corresponding material basin 15 on the material transport trolley 2 through the discharge pipe 8.14.

[0042] A connecting frame 8.11 is fixed to the side wall of the bracket 8.1, and a telescopic cylinder 8.12 is provided on the connecting frame 8.11. The telescopic end of the telescopic cylinder 8.12 is hinged to the connecting beam 8.9, and the cylinder end of the telescopic cylinder 8.12 is hinged to the connecting frame 8.11; by controlling the extension and retraction of the telescopic cylinder 8.12, the sliding of the corresponding first plugboard 8.7 and the second plugboard 8.8 is controlled.

[0044] In the initial state, the top feed port and the bottom discharge port of the discharge pipe assembly 8.6 are sealed by the first plug plate 8.7 and the second plug plate 8.8, and the staff adds urea raw materials into the silo 8.13; when the transfer self-moving trolley 9 moves to the bottom of the discharge pipe 8.14, the telescopic cylinder 8.12 corresponding to the first plug plate 8.7 is first actuated to control the first plug plate 8.7 to slide, so that the discharge hole 8.10 on it corresponds to the top feed port of the discharge pipe assembly 8.6, and the raw materials in the silo 8.13 begin to enter the discharge pipe assembly 8.6, until it is full, and the telescopic cylinder 8.12 is controlled to drive the first plug plate 8.7 to close the feed port.

[0045] The telescopic cylinder 8.12 corresponding to the second plug plate 8.8 is controlled to move, and the second plug plate 8.8 is driven to slide, so that the discharge hole 8.10 on it corresponds to the bottom discharge port of the discharge pipe assembly 8.6, so that the raw materials in the discharge pipe assembly 8.6 flow into the corresponding material basin 15 along the discharge pipe 8.14, and the volume of each discharge pipe assembly 8.6 meets the amount of raw materials carried by a corresponding material basin 15. In this way, rapid feeding is achieved, which greatly reduces the labor intensity and improves work efficiency; when the material basin 15 is connected with the material, the raw materials in the corresponding discharge pipe assemblies 8.6 are unloaded, the second plug plate 8.8 is controlled to be closed, and the first plug plate 8.7 is opened, and the material is continuously loaded into the discharge pipe assembly 8.6, and the above process is repeated to feed the empty material basin 15 on the incoming transfer self-moving trolley 9.

After the urea feeder 8 completes the loading of the material transport trolley 2 into the loading basin 15, the traction mechanism 12 on the kiln-entering self-moving trolley 10 is controlled to pull the material transport trolley 2 on the transfer self-moving trolley 9 out onto the kiln-entering self-moving trolley 10, and the kiln-entering self-moving trolley 10 is controlled to drive the material transport trolley 2 to move between the pushing mechanism 11 and the kiln head of the calcining kiln 1, and the material transport trolley 2 is pushed into the calcining kiln 1 along the track 13 by the pushing mechanism 11.

In this embodiment, limit switches are set at relevant positions, which are triggered to feedback to the DCS. The feedback signal is used to control the corresponding actuator to act through DCS to realize automated production; specifically, at the upper and lower limit positions of the furnace door 14, the kiln discharge self-moving trolley 3 stops at the kiln tail and one end of the transition frame 4, the transfer self-moving trolley 9 stops at the other end of the transition frame 4 and below the urea feeder 8, the kiln entry self-moving trolley 10 stops at the kiln head and one side of the urea feeder 8, and limit switches are installed on the kiln entry self-moving trolley 10, the transfer self-moving trolley 9, the kiln discharge self-moving trolley 3 and other related positions.

[0049] Working process: When the kiln self-moving trolley 3 moves to the kiln tail of the calcining kiln 1 and touches the limit switch, the limit switch feeds back a signal to the DCS, and the kiln tail oil cylinder is controlled by the DCS to drive the furnace door 14 to open, until the furnace door 14 rises to the limit switch, and then feeds back a signal to the DCS, and the traction mechanism 12 of the kiln self-moving trolley 3 is controlled by the DCS to pull the material transport trolley 2 at the kiln tail into place, and the pulled-out material transport trolley 2 triggers the limit switch on the kiln self-moving trolley 3, and the kiln tail furnace door 14 is controlled by the DCS to descend and close, until it reaches the position to trigger the corresponding limit switch, and then the kiln self-moving trolley 3 carries the material transport trolley 2 to move At the same time, the kiln-entering self-moving trolley 10 carries the loaded material transport trolley 2 from the urea feeder 8 to the kiln head of the calcining kiln 1. After moving into position, a signal is fed back to the DCS, and the DCS controls the furnace door 14 at the kiln head to rise until the limit switch feedback signal is triggered. The DCS controls the pushing mechanism 11 to push the material transport trolley 2 on the kiln-entering self-moving trolley 10 into the calcining kiln 1. After the pushing cylinder 11.2 of the pushing mechanism 11 is retracted, the furnace door 14 at the kiln head descends and closes, triggering the corresponding limit switch. The DCS controls the kiln-entering self-moving trolley 10 to return to the urea feeder 8 to wait.

[0050] The kiln self-moving trolley 3 carries the material transport trolley 2 to one end of the transition frame 4, triggers the limit switch, and feeds back a signal to the DCS. The DCS controls the traction mechanism 12 on the kiln self-moving trolley 3 to push the material transport trolley 2 onto the transition frame 4. At the same time, the material transport trolleys 2 covering the transition frame 4 are pushed to move one station, and the material transport trolley 2 at the end is pushed onto the transfer self-moving trolley 9 until it touches the limit switch on the transfer self-moving trolley 9. The signal is fed back to the DCS, and the DCS controls the transfer self-moving trolley 9 to move toward the urea feeder 8. At the same time, the material finishing machine 5 starts to sort the material basin 15 on the material transport trolley 2 at the corresponding station. At the same time, the manipulator 6 is controlled to start moving, grab the material basin 15 on the material transport trolley 2 at the corresponding station and pour the material into the crusher 7 for crushing.

[0051] After the transfer self-moving trolley 9 moves into position, a feedback signal is sent to the DCS to control the urea feeder 8 to start feeding. After the feeding is completed, a feedback signal is sent to the DCS to control the traction mechanism 12 of the kiln-entering self-moving trolley 10 to pull the material transport trolley 2 on the transfer self-moving trolley 9 onto the kiln-entering self-moving trolley 10, and the transfer self-moving trolley 9 returns to the other end of the transition frame 4. At this point, one automatic production is completed, and the next production is repeated according to the above process, thereby realizing the automated production of crude cyanuric acid.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
