[0022] The following disclosure provides many different implementation modes or examples for implementing different solutions of the present utility model.

[0023] Referring to Figures 1 to 7 As shown, in an embodiment of the present utility model, a material metering system for a containerized asphalt reactor includes a reaction container 1, a hopper 2, a solid material conveying pipeline 3, a liquid material conveying pipeline 4, and an exhaust gas treatment equipment 5;

[0024] There is a stirring chamber (not shown in the figure) inside the reaction container 1. The top of the reaction container 1 is provided with a feed hole and an installation cover 11. The feed hole is communicated with the stirring chamber. The installation cover 11 covers the feed hole (not shown in the figure). The hopper 2 is located above the installation cover 11. The installation cover 11 is provided with a metering valve 111 and a driving motor 112 for driving the metering valve 111 to operate. The metering valve 111 connects the hopper 2 and the installation cover 11. The solid material conveying pipeline 3 is connected to the hopper 2;

[0025] The liquid material conveying pipeline 4 is connected to the installation cover 11, and a flowmeter 41 is provided on the liquid material conveying pipeline 4; The exhaust gas treatment equipment 5 is connected to the side of the installation cover 11 for treating the exhaust gas output from the reaction container 1;

[0026] During use: According to the work requirements, the worker controls the operation of the metering valve 111 by controlling the action of the driving motor 112, so that the solid material falls from the hopper 2, enters the mixing chamber after passing through the feeding hole. When the solid material in the hopper 2 is almost consumed, the solid material can be supplemented to the hopper 2 through the solid material conveying pipeline 3. At the same time, the input of the liquid material is controlled through the liquid material conveying pipeline 4, and the flowmeter 41 on the liquid material conveying pipeline 4 is used to monitor the amount of the liquid material input, so as to control the quantitative input of the liquid material. When the ratio of the input solid material and liquid material reaches the preset range, the input of the two materials is stopped, and then the mixing chamber mixes and processes the input materials. The waste gas generated during the processing process will enter the waste gas treatment equipment 5 for treatment after passing through the installation cover 11; in this way, the amount of the input materials can be more accurately controlled, the production effect is improved, and the waste of materials is avoided.

[0027] The specific structure of the reaction container 1 can refer to Patent CN202121612044.1, which will not be elaborated in this embodiment.

[0028] Preferably, it further includes a storage tank 31 for storing solid materials. The solid material conveying pipeline 3 connects the hopper 2 and the storage tank 31, and a first conveying pump 32 is provided on the solid material conveying pipeline 3. The first conveying pump 32 is used to supplement the solid material in the storage tank 31 to the hopper 2;

[0029] Specifically, when the solid material in the hopper 2 is almost consumed, the first conveying pump 32 can be started to extract the solid material in the storage tank 31 by the first conveying pump 32, so that the solid material enters the hopper 2 after passing through the solid material conveying pipeline 3, thus completing the supplement of the solid material.

[0030] More preferably, it further includes a liquid storage tank 42 for storing liquid materials. The liquid material conveying pipeline 4 connects the liquid storage tank 42 and the installation cover 11, and a second conveying pump 43 is provided on the liquid material conveying pipeline 4. The second conveying pump 43 is used to convey the liquid material in the liquid storage tank 42 to the mixing chamber;

[0031] Specifically, when it is necessary to input liquid materials into the mixing chamber, the second conveying pump 43 is controlled to extract the liquid materials in the liquid storage tank 42 by the second conveying pump 43, so that the liquid materials enter the mixing chamber after passing through the liquid material conveying pipeline 4. According to the work requirements, the flowmeter 41 is used to monitor the amount of the liquid materials input into the mixing chamber, and the second conveying pump 43 can be stopped when the required amount is reached.

[0032] In this embodiment, it further includes a rotary motor 6 disposed on the side surface of the mounting cover 11 and a material pushing plate 61 disposed on the rotating shaft of the rotary motor 6. The axis of the rotating shaft of the rotary motor 6 is horizontally arranged, and the material pushing plate 61 is located inside the mounting cover 11;

[0033] The rotary motor 6 is used to drive the material pushing plate 61 to rotate so as to push the solid material falling from the hopper 2, thereby dispersing the solid material in the stirring chamber;

[0034] Specifically, in order to prevent the solid material from accumulating at the same position in the stirring chamber and affecting the stirring effect, when the driving motor 112 drives the metering valve 111 to open and the solid material in the hopper 2 falls, the rotary motor 6 drives the rotating shaft to rotate clockwise and counterclockwise repeatedly, thereby driving the rotation of the material pushing plate 61 to push the falling solid material, changing the movement path of the solid material and then dropping it into the stirring chamber after passing through the feed hole, thereby dispersing the solid material into the stirring chamber to improve the reaction efficiency and effect during the stirring process.

[0035] Preferably, the waste gas treatment device 5 includes an activated carbon adsorption box 51, a draft fan 52, and a combustion box 53. The activated carbon adsorption box 51 is provided with an air inlet pipe 511 and an air outlet pipe 512. The air inlet pipe 511 is connected to the side surface of the mounting cover 11, and the air outlet pipe 512 is sequentially connected to the draft fan 52 and the combustion box 53;

[0036] Further, the draft fan 52 guides the flow of the waste gas in the stirring chamber, so that the waste gas flows out from the feed hole and enters the mounting cover 11, and after passing through the air inlet pipe 511, it is first subjected to preliminary waste gas treatment in the activated carbon adsorption box 51, and then enters the combustion box 53 from the air outlet pipe 512 to burn the waste gas, reducing the harmful gases generated during combustion and avoiding environmental pollution.

[0037] In this embodiment, it further includes a collection box 7, a filter plate 8, and a clamp 9. The collection box 7 is provided with an inlet 71 and an outlet 72. The inlet 71 is communicated with one side of the mounting cover 11. The filter plate 8 is located in the collection box 7 and blocks between the inlet 71 and the outlet 72 to filter the solid material in the waste gas; a connector 73 is provided at the outlet 72, and the air inlet pipe 511 is detachably connected to the connector 73 through the clamp 9;

[0038] Specifically, during the process of stirring the material in the stirring chamber, the solid material will be thrown out, and the rising waste gas will carry the solid material and flow out from the feed hole. In order to prevent the solid material from accumulating in the air inlet pipe 511, the inlet 71 of the collection box 7 is communicated with one side of the mounting cover 11, and the filter plate 8 is used to block the solid material. When the waste gas passes through the filter plate 8, the solid material will be left in the collection box 7, and the filtered waste gas will then enter the air inlet pipe 511, thus preventing the solid material from accumulating in the air inlet pipe 511;

[0039] After a period of time, when the collection box 7 accumulates a certain amount of solid materials, it needs to be cleaned. The worker can loosen the clamp 9, remove the air inlet pipe 511, and then clean the collection box 7.

[0040] Preferably, a socket 74 is provided at the top of the collection box 7, and the filter plate 8 is inserted into the collection box 7 through the socket 74.

[0041] When the filter plate 8 needs to be replaced or the collection box 7 needs to be cleaned, the worker can directly pull out the filter plate 8 upward from the socket 74. When the cleaning of the collection box 7 is completed or a new filter plate 8 needs to be installed back into the collection box 7, just insert the filter plate 8 directly into the socket 74, which is simple and convenient.

[0042] In this embodiment, the filter plate 8 includes a cover plate 81, a connecting plate 82, a bottom plate 83, and two side plates 84. The connecting plate 82 is rectangular, and the cover plate 81, the bottom plate 83, and the side plates 84 are respectively arranged on the four sides of the connecting plate 82 to enclose a chamber 85 on the connecting plate 82. A filter cotton (not shown in the figure) is detachably installed in the chamber 85.

[0043] The cover plate 81 and the bottom plate 83 are arranged opposite to each other. A plurality of through holes 821 are provided on the connecting plate 82, and the cover plate 81 can cover the socket 74.

[0044] Specifically, the filter cotton is installed in the chamber 85 formed by the cooperation of the cover plate 81, the bottom plate 83, and the side plates 84. Then, the connecting plate 82 is inserted into the collection box 7 through the socket 74. In this way, the cover plate 81 will cover the socket 74, reducing the outflow of waste gas from the socket 74. When the waste gas enters the collection box 7 from the inlet 71, the waste gas will first pass through the through holes 821, then pass through the filter cotton, and the solid materials will be blocked by the filter cotton, so that the solid materials are filtered out before the waste gas enters the air inlet pipe 511, avoiding the accumulation of solid materials in the pipeline.

[0045] More preferably, the bottom plate 83 and the connecting plate 82 are connected by a spring hinge 86 to press the filter cotton in the chamber 85.

[0046] Specifically, by using the spring hinge 86 to connect the bottom plate 83 and the connecting plate 82, when installing the filter cotton, first turn over the bottom plate 83 to make the bottom plate 83 in a vertical state, so that the bottom of the chamber 85 is in an open state. Then insert the filter cotton from the bottom, and the side plate 84 will play a guiding role when the filter cotton is inserted. After completely inserting the filter cotton into the chamber 85, release the bottom plate 83 and use the spring hinge 86 to reset the bottom plate 83. In this way, the filter cotton will be pressed in the chamber 85, thus completing the installation of the filter cotton. Then insert the connecting plate 82 into the collection box 7 from the socket 74. When the filter cotton needs to be replaced, pull out the filter plate 8, turn over the bottom plate 83 again to open the bottom of the chamber 85, and then pull out the filter cotton and insert another filter cotton into the chamber 85 from the bottom, making it more convenient to replace the filter cotton.

[0047] Preferably, the side plate 84 includes a connecting section 841 and a limiting section 842. The connecting section 841 and the limiting section 842 form an L-shaped structure. The connecting section 841 is connected to the connecting plate 82, and the limiting section 842 is opposite to the connecting plate 82.

[0048] Furthermore, the connecting section 841 is connected to the connecting plate 82 and plays a role in support and fixation, while the limiting section 842 is opposite to the connecting plate 82. Its main function is to fix the filter cotton in the chamber 85 when the filter cotton is installed, prevent the displacement of the filter cotton, and ensure that the filter cotton can be set in the specified position.

[0049] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
