Description

Technical Field

[0001] The utility model relates to the technical field of activated carbon processing, in particular to a carbonization furnace feeding material feeding system. Background Art

[0002] The activated carbon preparation process mainly includes grinding, kneading, granulation, carbonization, activation and packaging, among which the carbonization process is one of the main heat treatment processes in the activated carbon preparation process. Among them, for granular or columnar activated carbon, the main feeding method currently used in the carbonization process is to use an electric hoist to lift the material bag to supply the charging buffer hopper, and then the charging buffer hopper supplies the carbonization furnace. This method requires manual loading of the activated carbon into the material bag first, and then sending it to the top of the buffer hopper for unloading. Activated carbon itself contains a large amount of carbon powder, and the loading and unloading process is prone to generate dust, which has a great impact on the health of workers.

[0003] CN212150900U discloses an activated carbon feeding device, including a feeding bin, a feeding bin, a lifting mechanism, a bag breaking mechanism, a dust removal mechanism and a material level control mechanism. The utility model has the beneficial effects of simple structure, single operation steps and continuous feeding.

[0004] CN215627772U discloses a raw material charging machine for a carbonizing furnace, comprising a storage box, a transfer box, a feeding channel, a connecting plate and a feeding pipe. A spiral conveying shaft is sleeved in the feeding pipe. The raw materials can be automatically added to the carbonizing furnace, which can effectively improve the feeding efficiency of the carbonizing furnace.

[0005] The above two solutions can only realize unmanned operation of a single carbonization furnace, and cannot feed multiple carbonization furnaces at the same time. Summary of the invention

[0006] In view of this, it is necessary to provide a carbonization furnace feeding material feeding system suitable for multiple carbonization furnaces.

[0007] A carbonization furnace feeding material feeding system includes a conveyor belt, a discharge mechanism, and a buffer bin. The conveyor belt is provided with a plurality of discharge mechanisms. The buffer bin is located below the discharge mechanism. The external carbonization furnace is located below the buffer bin. A valve is provided between the buffer bin and the carbonization furnace to control the activated carbon entering the carbonization furnace. The discharge mechanism includes a frame, an electric push rod, and a baffle. The upper end of the frame is fixedly connected to the body of the electric push rod, and the telescopic rod of the electric push rod is fixedly connected to the baffle. The conveyor belt is correspondingly provided with a plurality of guide grooves. The buffer bin is located directly below the guide groove to transport the activated carbon to the buffer bin through the guide groove. The baffle is tilted on the conveyor belt, and the feed port of the guide groove is located at the end of the baffle to guide the activated carbon from the conveyor belt into the guide groove. A side plate is provided on the side of the conveyor belt close to the guide groove to prevent the activated carbon from falling from the conveyor belt during the process of entering the guide groove.

[0008] Preferably, a buffer plate is provided at the upper end of the buffer bin to reduce the impact force when the activated carbon falls, and a plurality of plate holes are provided on the buffer plate, through which the activated carbon enters the buffer bin.

[0009] Preferably, the buffer plate is arranged at an angle so that the activated carbon can slide down along the buffer plate and is evenly distributed in the buffer bin.

[0010] Preferably, the plate holes on the buffer plate are in the shape of long strips and gradually widen along the downward direction so that the activated carbon is evenly distributed in the buffer bin.

[0011] Preferably, the edges of the plate holes are provided with skirts to reduce the impact of the activated carbon when it falls and to prevent dust.

[0012] Preferably, a flow sensor is provided on the side of the guide groove, and correspondingly, the carbonization furnace feeding system also includes a controller, which is electrically connected to the flow sensor and the electric push rod to control the extension and retraction of the electric push rod according to the flow rate of the falling activated carbon.

[0013] Preferably, the conveyor belt is provided with a plurality of electronic belt scales, the number of which is the same as the number of guide grooves, and the electronic belt scales are located in front of the baffle. Correspondingly, the carbonization furnace feeding system also includes a controller, which is electrically connected to the electronic belt scale and the electric push rod to control the extension and retraction of the electric push rod according to the weight of the activated carbon transported by the conveyor belt.

[0014] Beneficial effect: When the carbonization furnace feeding system of the utility model is in use, the expansion and contraction of the baffle of the unloading mechanism is controlled according to the amount of activated carbon in the buffer bin, thereby controlling the falling of the activated carbon. When there is less activated carbon in the buffer bin, the baffle of the unloading mechanism extends forward to intercept the activated carbon from the conveyor belt. Since the baffle is inclined, under the guidance of the baffle, the activated carbon will enter the guide groove under the drive of the conveyor belt, and further slide into the buffer bin; when there is more activated carbon in the buffer bin, the baffle of the unloading mechanism retracts, and under the drive of the conveyor belt, the activated carbon is transported to the next baffle. Similarly, if there is more activated carbon in the buffer bin here, the baffle retracts, so that the conveyor belt continues to transport the activated carbon to the next baffle. In this way, through the cooperation of the conveyor belt and the unloading mechanism, multiple carbonization furnaces can be fed at the same time, thereby improving the feeding efficiency of the carbonization furnace.

[0015] Figure 1 It is a structural schematic diagram of the feeding system of the carbonization furnace of the utility model.

[0016] In the figure: a carbonization furnace feeding system 10, a conveyor belt 20, a side plate 201, a discharge mechanism 30, a frame 301, an electric push rod 302, a baffle 303, a buffer bin 40, a buffer plate 401, a plate hole 4011, and a carbonization furnace 50. DETAILED DESCRIPTION

[0017] In order to more clearly illustrate the technical solutions of the embodiments of the utility model, the drawings required for use in the embodiments are briefly introduced below. Obviously, the drawings described below are some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.

[0018] Please see Figure 1 The carbonization furnace 50 feeding material feeding system 10 includes a conveyor belt 20, a discharge mechanism 30, and a buffer bin 40. The conveyor belt 20 is provided with a plurality of discharge mechanisms 30. The buffer bin 40 is located below the discharge mechanism 30. The external carbonization furnace 50 is located below the buffer bin 40. A valve is provided between the buffer bin 40 and the carbonization furnace 50 to control the activated carbon to enter the carbonization furnace 50. The discharge mechanism 30 includes a frame 301, an electric push rod 302, and a baffle 303. The upper end of the frame 301 is fixedly connected to the body of the electric push rod 302. The telescopic rod of the electric push rod 302 is fixedly connected to the baffle 303. A plurality of guide grooves are correspondingly provided on the conveyor belt 20. The buffer bin 40 is located directly below the guide grooves to transport the activated carbon to the buffer bin 40 through the guide grooves. The baffle 303 is obliquely arranged on the conveyor belt 20. The feed port of the guide groove is located at the end of the baffle 303 to guide the activated carbon from the conveyor belt 20 into the guide groove. A side plate 201 is provided on one side of the conveyor belt 20 close to the guide groove to prevent the activated carbon from falling from the conveyor belt 20 during the process of entering the guide groove.

[0019] The conveyor belt 20 of the utility model is used to convey the activated carbon from the granulation process to the buffer bin 40 and further to the carbonization furnace 50. In order to facilitate the placement of the unloading structure, the conveyor belt 20 is not provided with a side plate 201 on the side close to the electric push rod 302; at the same time, in order to facilitate the guidance of the activated carbon to the buffer bin 40, a guide groove is provided on the side close to the baffle 303, and under the action of the baffle 303, the activated carbon can enter the guide groove along the baffle 303. In the blocking process, it is inevitable that some activated carbon will fall from the side of the guide groove. In order to avoid this situation, a side plate 201 is provided on the conveyor belt 20 on the side close to the guide groove. When the baffle 303 is completely in contact with the side plate 201, the activated carbon can be completely blocked. When the baffle 303 shrinks and forms a gap with the side plate 201 , the activated carbon will be transported from the gap between the baffle 303 and the side plate 201 to the next baffle 303 through the conveyor belt 20 .

[0020] The buffer bin 40 of the utility model is located above the carbonization furnace 50. The heat of the carbonization furnace 50 can preheat the activated carbon, thereby reducing the moisture content of the activated carbon, which is beneficial to reducing the carbonization time and the heat energy consumed by carbonization.

[0021] Activated carbon contains carbon powder, which can easily cause dust and other problems during the falling process, which will have a great impact on the working environment and will also cause damage to equipment such as motors. In a preferred embodiment, a buffer plate is provided at the upper end of the buffer bin 40 to reduce the impact of the activated carbon when it falls. The buffer plate is provided with a plurality of plate holes 4011, and the activated carbon enters the buffer bin 40 through the plate holes 4011. An elastic bracket can be provided at the bottom of the buffer plate to reduce the kinetic energy of the activated carbon falling onto the buffer plate, making it less likely to cause floating dust.

[0022] Furthermore, the buffer plate is tilted so that the activated carbon can slide down along the buffer plate and be evenly distributed in the buffer bin 40. By tilting the buffer plate, when the activated carbon falls onto the buffer plate, part of the kinetic energy will be transferred along the inclined surface of the buffer plate, which can reduce the kinetic energy of the dust when it rebounds, making it less likely for the dust to float and spread.

[0023] Furthermore, the plate holes 4011 on the buffer plate are in the shape of long strips and gradually widen along the downward direction, so that the activated carbon is evenly distributed in the buffer bin 40. When the activated carbon just falls onto the buffer plate, the amount is very large. Then, as the activated carbon slides down along the buffer plate, the amount of activated carbon falling from the plate holes 4011 gradually increases, and the amount of activated carbon on the buffer plate gradually decreases. The gradually widening plate holes 4011 help the activated carbon to fall from the plate holes 4011 more easily, so that the activated carbon falling into the buffer bin 40 is more evenly distributed.

[0024] The activated carbon falling into the buffer bin 40 will still generate floating dust. In order to further reduce the floating dust, the edge of the plate hole 4011 is further provided with a skirt to reduce the impact of the activated carbon when it falls and prevent dust. First, the activated carbon has a certain kinetic energy when it falls from the plate hole 4011. The blocking of the skirt can reduce the kinetic energy of the activated carbon. At the same time, the floating dust generated when the activated carbon falls into the buffer bin 40 will be blocked by the skirt. Part of the activated carbon will be adsorbed by the skirt, and part of the activated carbon will fall back into the buffer bin 40, thereby reducing the amount of floating dust in the environment. The material of the skirt is a flexible wear-resistant material, such as nylon, wear-resistant rubber, etc.

[0025] The unloading mechanism 30 of the utility model can control the extension and retraction of the baffle 303 either manually or by a controller. When the extension and retraction of the baffle 303 is controlled manually, it is necessary to judge whether the activated carbon needs to be delivered to the corresponding buffer bin 40 by experience, or directly observe the amount of activated carbon in the buffer bin 40 to decide whether to replenish the activated carbon. On the one hand, this method will increase labor costs, and on the other hand, when employees are slack, problems such as empty or full bins are prone to occur. When the controller controls the extension and retraction of the baffle 303,

[0026] In a preferred embodiment, a flow sensor is provided on the side of the guide groove, and accordingly, the carbonization furnace 50 feeding material feeding system 10 also includes a controller, which is electrically connected to the flow sensor and the electric push rod 302 to control the extension and retraction of the electric push rod 302 according to the flow rate of the falling activated carbon.

[0027] The controller is provided with a flow limit value of activated carbon. When the flow rate of activated carbon reaches the flow limit value of activated carbon, it indicates that there is a lot of activated carbon in the buffer bin 40, then the controller controls the electric push rod 302 to contract, stops the activated carbon from being discharged, and clears the flow rate; after the buffer bin 40 has been supplied for a predetermined time, the flow rate is counted again, and the unloading mechanism 30 is controlled to supply materials to the buffer bin 40.

[0028] In another preferred embodiment, a plurality of electronic belt scales are provided on the conveyor belt 20, and the number of the electronic belt scales is the same as the number of the guide grooves. The electronic belt scales are located in front of the baffle 303. Correspondingly, the carbonization furnace 50 feeding material feeding system 10 also includes a controller, and the controller is electrically connected to the electronic belt scale and the electric push rod 302 to control the extension and retraction of the electric push rod 302 according to the weight of the activated carbon transported by the conveyor belt 20.

[0029] The controller is provided with a weight limit value for the activated carbon. When the weight of the activated carbon flowing through the electronic belt scale reaches the weight limit value, the controller controls the electric push rod 302 to retract, stops the unloading of the activated carbon, and resets the electronic belt scale. After that, after the buffer bin 40 has supplied the material for a predetermined period of time, the weight measurement is started again, and the unloading mechanism 30 is controlled to supply the material into the buffer bin 40.

[0030] The above disclosure is only a preferred embodiment of the present invention, and it certainly cannot be used to limit the scope of the present invention. A person skilled in the art can understand that all or part of the processes of the above embodiments and equivalent changes made according to the claims of the present invention still fall within the scope of the present invention.
