Description

Technical Field

[0001] The utility model relates to the technical field of multi-purpose cold material bins, in particular to a control device for a multi-purpose cold material bin. Background Art

[0002] The control device of the cold silo refers to the process of monitoring, adjusting and managing the internal environment and operation status of the cold silo through the control system. The control of the cold silo is to effectively manage and adjust its internal environment and operation through the intelligent control system to ensure the quality and safety of the materials in the silo and improve production efficiency and operation stability;

[0003] For example, a method for automatic adjustment of cold material bins with publication number CN109554992B includes the following steps: 1. Calibrate each cold material bin by weighing method; 2. Calibrate the specifications of the cold material bin; 3. Give the initial frequency of the cold material bin; 4. Calibrate the continuous material level meter of the hot material bin and its high and low positions; 5. Adjust the material level change; 6. Adjust the material level. Taking the non-standard cold material in the cold material bin into consideration, the cold material formula is calculated through the target formula, and the relationship between the total output and the cold material formula is used to determine the cold material bin frequency at the beginning of production. Finally, the cold material formula is automatically adjusted through the change of the hot material bin position and the height of the hot material bin position, which solves the problem of deviation between the actual supply of the cold material bin and the demand of the hot material bin due to the presence of non-standard materials in the cold material bin.

[0004] The above-mentioned automatic adjustment method for cold material bin automatically adjusts the cold material formula by changing the hot material bin position and the height of the hot material bin position, which can avoid the problem of deviation in demand. However, when there is a set of asphalt mixture mixing equipment and a set of crushing and screening equipment or stripping equipment or commercial mixing equipment on the same site, the two sets of equipment will not be used at the same time, the cost required is relatively high, and it causes a waste of resources.

[0011] Furthermore, when the switching cylinder at the lower outlet of the three-way switching valve aligns the flat belt with the conveying belt of equipment two, the cold material bin one, cold material bin two, cold material bin three, cold material bin four and the flat belt are controlled by the control system of equipment two.

[0012] Furthermore, an asphalt mixing station switch is provided on the left side of the cold material bin 1, and the left side of the asphalt mixing station switch is connected to B-24V.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Embodiment 1:

[0029] like Figure 1-Figure 7The technical solution shown, in order to solve the problem of high cost consumption and waste of resources, discloses: a cold material bin 1 and a cold material bin 2 2 arranged on the right side of the cold material bin 1, a cold material bin 3 3 is arranged on the right side of the cold material bin 2, and a cold material bin 4 4 is arranged on the right side of the cold material bin 3 3;

[0030] A flat belt 5 is provided on the right side of the cold material bin 4, and a three-way switching valve 6 is provided on the right side of the flat belt 5, and two output ends on the right side of the three-way switching valve 6 are provided with a device one conveying belt 7 and a device two conveying belt 8;

[0031] The conveying belt 7 of device one is connected to device one, and the conveying belt 8 of device two is connected to device two. Device one is a cold material control device, and device two is a cold material control device and a cold material bin switching control device. When the upper outlet of the three-way switching valve 6 is aligned with the conveying belt 7 of device one, the cold material bin one 1, cold material bin two 2, cold material bin three 3, cold material bin four 4 and flat belt 5 are controlled by the control system 10 of device one, and when the switching cylinder at the lower outlet of the three-way switching valve 6 aligns the flat belt 5 with the conveying belt 8 of device two, the cold material bin one 1, the cold material bin two 2, the cold material bin three 3, the cold material bin four 4 and the flat belt 5 are controlled by the control system 10 of device one. Two 2, cold material bin three 3, cold material bin four 4 and flat belt 5 are controlled by the control system 11 of equipment two. The left side of cold material bin one 1 is provided with asphalt mixing station switch 9, and the left side of asphalt mixing station switch 9 is connected to B-24V. Cold material bin one 1, cold material bin two 2, cold material bin three 3, three-way switching valve 6 and the upper end of asphalt mixing station switch 9 are connected to the cold material discharge form circuit controlled by the cylinder, and the cold material discharge form controlled by the cylinder is divided into three control circuits, and the three control circuits are control 10 of equipment one, control 11 of equipment two, and control 12 in the control box;

[0032] In the embodiment, when the use of device 1 is normal, the outlet of the three-way switching valve 5 is facing the direction of the conveying belt 7 of device 1. At this time, the cold material bin 1, cold material bin 2, cold material bin 3, cold material bin 4, and flat belt 5 are all controlled by the control system 10 of device 1. At this time, KA10 is not powered, the normally closed contact is closed, and the switching control box does not need to be operated. Device 1 can use K1 to actuate cold material bin 1 to unload, use K2 to actuate cold material bin 2 to unload, use K3 to actuate cold material bin 3 to unload, and use K4 to actuate cold material bin 4 to unload. The vibration of cold material bin 1 is also controlled by device 1, because the vibration control circuit of device 2 is cut off by the normally open contact of KA10, avoiding the situation where two devices are controlled at the same time. The power supply circuit cuts off the electrical signal association between the two devices through the contactor KM16F-2, avoiding the situation where the power supply circuits of the two devices are connected at the same time when the contactors GKM1 and KM16F fail.

[0033] Flat belt 5 is also controlled by device one. The flat belt 5 control circuit of device two is cut off by intermediate relay KA10, so there will be no malfunction of device two. When device one wants to start flat belt 5, air switch GQF2 is closed, the normally closed contact of control circuit KA10 is in closed state, coil of contactor KM16E-2 is energized, and main contact is closed. When the start button of device one is pressed, GK2 is turned on, coil of contactor GKM2 is energized, and main contact is closed. At this time, power line UVW to GU1GV1GW1 is turned on, and flat belt 5 motor M16E is energized and runs.

[0034] When using device 2, it is necessary to switch the knob on the switch control box to device 2. At this time, the intermediate relay KA10 is energized, the normally open contact is closed, the normally closed contact is disconnected, and the three-way switching cylinder will switch the belt outlet to the direction of the conveying belt 8 of device 2. At this time, the cold material bin 1, cold material bin 2, cold material bin 3, cold material bin 4, and flat belt 5 are all controlled by the control system 11 of device 2. Device 2 can use KY170 to actuate the cold material bin 1 to unload, use K171 to actuate the cold material bin 2 to unload, use K172 to actuate the cold material bin 3 to unload, and use K174 to actuate the cold material bin 4 to unload. The vibration of cold material bin 1 is also controlled by device 2, because the power line of device 1 is cut off by the contactor KM16F-2 at this time, and the electrical signals of the two devices will not be mixed even if a misoperation occurs. Flat belt 5 is also controlled by device 2. At this time, contactor KM16E-2 is disconnected, control line Q16E is connected, and KA10 is connected. When the start button is pressed, KY16E is connected, the contactor KM16E coil is energized, the main contacts are closed, and M16E of flat belt 5 is powered and operated through the line 1L1 / 1L2 / 1L3 to GU1GV1GW1.

[0035] Through the reasonable coordination design of mechanical and electrical, the purpose of using one cold material system to supply two sets of equipment at the same time is achieved, which reduces the cost of purchasing another cold material system and saves resources.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
