Description

Technical Field

[0001] This invention relates to the field of dust removal technology, specifically to an automatic dust removal system for the production process of manufactured sand with intelligent monitoring function. Background Technology

[0002] With the continuous acceleration of urbanization, more and more modern buildings are appearing in people's daily life and production. Sand and gravel are one of the indispensable raw materials in the construction process. However, relying solely on the mining of traditional natural sand and gravel can no longer meet modern needs. Therefore, manufactured sand has gradually emerged, which uses corresponding raw materials and equipment to crush them. In the process of manufactured sand production, dust is one of the main factors affecting the on-site working environment. Therefore, the manufactured sand production process generally needs to be equipped with an automatic dust removal system.

[0003] Existing automatic dust removal systems in the manufactured sand production process generally take many forms. One such system uses negative pressure to extract and reprocess the air and dust on site, including spraying. However, in practical applications, there is a problem that dusty air tends to flow too fast in the spraying section, resulting in insufficient contact with the spraying liquid and thus inadequate treatment of the dusty air by the spraying liquid. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic dust removal system for the manufactured sand production process with intelligent monitoring function, so as to solve the problem in the background that the dust-laden airflow velocity in the automatic dust removal system for the manufactured sand production process is too fast, resulting in inadequate spraying treatment.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] An automatic dust removal system for manufactured sand production process with intelligent monitoring function includes a first spray treatment chamber, a second spray treatment chamber installed on the top of the first spray treatment chamber, and an atomizing water distributor installed through one side of both the first and second spray treatment chambers. The side of the first and second spray treatment chambers near the atomizing water distributors is connected to a multi-way connecting pipe, and the end of the multi-way connecting pipe away from the first spray treatment chamber is connected to two sets of air inlet pipes.

[0007] Both the first and second spray treatment chambers are connected to exhaust pipes on the side away from the multi-way connecting pipe, and the end of the exhaust pipe away from the first spray treatment chamber is connected to a negative pressure extraction pipe. Both ends of the inner wall of the exhaust pipe are provided with arc-shaped receiving grooves.

[0008] A rotating shaft passes through the outer wall of the exhaust pipe, and a first gear is installed on the outer side of the rotating shaft. A limit hole is provided on the outer wall of the rotating shaft.

[0009] Rotary ball valves are installed at both ends of the rotating shaft. A large-diameter main passage hole is opened at one end of the outer wall of the rotating ball valve, and small-diameter secondary passage holes are reserved on both sides of the outer wall of the rotating ball valve.

[0010] The first spray treatment chamber is equipped with a drive mechanism for driving the rotating shaft to rotate;

[0011] An arc-shaped extrusion block is installed on the outer wall of the rotating ball valve near the first spray treatment chamber. An installation chamber is installed on the top of the atomizing water distributor. An active mechanism for blocking air in the first and second spray treatment chambers is provided inside the installation chamber.

[0012] As a further aspect of the present invention: a connecting rope is connected to the outer side of the air inlet pipe away from the multi-way connecting pipe, and a dust detector is connected to the end of the connecting rope away from the air inlet pipe.

[0013] As a further aspect of the present invention: the central axis of the rotating shaft is perpendicular to the central axis of the exhaust pipe, and the rotating shaft and the exhaust pipe are rotatably connected.

[0014] As a further aspect of the present invention: the driving mechanism includes a motor, which is installed on the side of the first spray treatment chamber near the exhaust pipe. The output end of the motor is connected to a reciprocating lead screw, and an incomplete rack is sleeved on the outer side of the reciprocating lead screw. Limiting rods are installed on both sides of the incomplete rack near the rotating shaft. A guide rod passes through one side of the incomplete rack, and the guide rod is fixedly connected to the first spray treatment chamber.

[0015] As a further aspect of the present invention: the incomplete rack and the reciprocating screw are threadedly connected, and the incomplete rack and the guide rod are slidably connected.

[0016] As a further aspect of the present invention: the movable mechanism includes a rack body, which is disposed inside the installation chamber. A spring is connected between the rack body and the installation chamber. A movable compression rod is installed on the side of the rack body near the exhaust pipe, and the movable compression rod extends through the installation chamber into the interior of the exhaust pipe.

[0017] As a further aspect of the present invention: the movable extrusion rod and the mounting chamber are slidably connected, and the movable extrusion rod and the rack body are integrally manufactured.

[0018] As a further aspect of the present invention: the active mechanism further includes a rotating wind deflector, which is evenly distributed throughout the bottom of the installation chamber and extends through the atomizing water distributor, and a second gear is installed on the top of the rotating wind deflector.

[0019] As a further aspect of the present invention: the central axis of the rotating wind deflector is perpendicular to the transverse central axis of the installation chamber, and the rotating wind deflector is rotatably connected to both the installation chamber and the atomizing water distributor.

[0020] As a further aspect of the present invention: the central axis of the second gear is perpendicular to the transverse central axis of the rack body, and the second gear and the rack body are meshed together.

[0021] The beneficial effects of this invention are:

[0022] (1) The present invention has two sets of rotating ball valves on the rotating shaft, one end of the rotating ball valve is provided with a large-diameter main passage hole, and the two sets of large-diameter main passage holes are oriented differently. The first spray treatment chamber is provided with a drive mechanism for driving the rotating shaft to rotate. This allows the two sets of exhaust pipes to be opened and closed intermittently during use, and the opening and closing states of the two sets of exhaust pipes are always opposite. Therefore, the dust-laden air can stay in the first spray treatment chamber or the second spray treatment chamber for a longer time, thereby increasing the spray treatment effect.

[0023] (2) The present invention has a small-diameter secondary through hole on the rotating ball valve, and the small-diameter secondary through hole is opposite to the large-diameter main through hole on the same group of rotating ball valves. This means that after the rotating ball valve is closed, the exhaust pipe is not completely closed, and a small amount of air can be discharged out through the small-diameter secondary through hole. This ensures that the air in the first spray treatment chamber and the second spray treatment chamber has a basic flow direction, thereby cooperating to complete the spraying work while avoiding backflow and other phenomena.

[0024] (3) The present invention has an arc-shaped extrusion block on the rotating ball valve and a meshing connection between the second gear and the rack body. When the rotating ball valve is turned to close the exhaust pipe, only a small amount of air is discharged through the small-diameter secondary through hole, so that the air in the first spray treatment chamber or the second spray treatment chamber is kept in basic airflow to cooperate with the spraying. The arc-shaped extrusion block will extrude the corresponding movable extrusion rod, so that the corresponding rotating wind deflector will rotate. This will cause the fan blades on the rotating wind deflector to form a certain angle with the airflow direction, thereby increasing the friction and blocking ability of the air. This will further reduce the airflow speed without hindering the airflow, thereby further ensuring the spraying effect.

[0025] (4) The present invention is equipped with a connecting rope and a dust detector on the air inlet pipe. After the staff aligns the end of the two sets of air inlet pipes away from the multi-way connecting pipe near the inlet and outlet of the manufactured sand, the dust detector can be further placed at a specified distance from the corresponding air inlet pipe. The dust detector can monitor the dust content in the surrounding air. When the dust content does not meet the standard, the staff can increase the negative pressure supply of the negative pressure extraction pipe until the monitoring result of the dust detector meets the requirements. Thus, the dust removal effect can be ensured through monitoring and adjustment. Attached Figure Description

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Example 1:

[0041] Please see Figures 1-4 as well as Figures 7-9 as well as Figure 11 As shown, the present invention is an automatic dust removal system for the production process of manufactured sand with intelligent monitoring function, including a first spray treatment chamber 1, a second spray treatment chamber 2 installed on the top of the first spray treatment chamber 1, and an atomizing water distributor 28 installed through one side of both the first spray treatment chamber 1 and the second spray treatment chamber 2. A multi-way connecting pipe 27 is connected to the side of the first spray treatment chamber 1 and the second spray treatment chamber 2 near the atomizing water distributor 28, and two sets of air inlet pipes 3 are connected to the end of the multi-way connecting pipe 27 away from the first spray treatment chamber 1.

[0042] During use, the air inlet pipe 3 can be a flexible corrugated pipe. A filter plate can be added to the end of the air inlet pipe 3 away from the multi-way connecting pipe 27 to block larger impurities. The opening of the air inlet pipe 3 away from the multi-way connecting pipe 27 is pulled and fixed to the vicinity of the feed inlet and discharge outlet of the manufactured sand equipment. At the same time, the atomizing water distributor 28 is connected to the spray liquid supply equipment. The two sets of atomizing water distributors 28 respectively basically seal the interior of the first spray treatment chamber 1 and the second spray treatment chamber 2, with only the part away from the multi-way connecting pipe 27 allowing air to pass through. Therefore, when dusty air enters the first spray treatment chamber 1 and the second spray treatment chamber 2 through the air inlet pipe 3 and the multi-way connecting pipe 27, it can only pass through the lower space inside the first spray treatment chamber 1 and the second spray treatment chamber 2, thereby ensuring that the atomizing water distributor 28 can perform the spraying task on the air.

[0043] Both the first spray treatment chamber 1 and the second spray treatment chamber 2 are connected to an exhaust pipe 4 on the side away from the multi-way connecting pipe 27, and the end of the exhaust pipe 4 away from the first spray treatment chamber 1 is connected to a negative pressure extraction pipe 5. Both ends of the inner wall of the exhaust pipe 4 are provided with arc-shaped receiving grooves 6.

[0044] The negative pressure extraction pipe 5 is connected to the exhaust equipment, which has a wind speed adjustment function. When the exhaust equipment is running, it can drive the outside air in through the air inlet pipe 3, and then through the multi-way connecting pipe 27, the first spray treatment chamber 1 and the second spray treatment chamber 2, the exhaust pipe 4, and the negative pressure extraction pipe 5, and finally exhaust it through the exhaust equipment. During this process, the air can be sprayed when it passes through the first spray treatment chamber 1 and the second spray treatment chamber 2, thereby completing the treatment task.

[0045] A rotating shaft 9 passes through the outer wall of the exhaust pipe 4, and a first gear 10 is installed on the outer side of the rotating shaft 9. A limiting through hole 11 is opened on the outer wall of the rotating shaft 9. The central axis of the rotating shaft 9 is perpendicular to the central axis of the exhaust pipe 4, and the rotating shaft 9 and the exhaust pipe 4 are rotatably connected, so that the rotating shaft 9 can rotate under the action of a corresponding external force.

[0046] Rotary ball valves 12 are installed at both ends of the rotating shaft 9. A large-diameter main passage hole 13 is opened at one end of the outer wall of the rotating ball valve 12, and small-diameter secondary passage holes 14 are reserved on both sides of the outer wall of the rotating ball valve 12.

[0047] The large-diameter main through holes 13 on the two sets of rotary ball valves 12 face opposite directions, the small-diameter auxiliary through holes 14 on the two sets of rotary ball valves 12 face opposite directions, the large-diameter main through holes 13 and the small-diameter auxiliary through holes 14 on the same set of rotary ball valves 12 face opposite directions, and the inner diameter of the large-diameter main through hole 13 is much larger than the inner diameter of the small-diameter auxiliary through hole 14.

[0048] When the rotating shaft 9 rotates, a set of rotating ball valves 12 can basically close the corresponding exhaust pipe 4, leaving only the small-diameter secondary through hole 14 to allow a small amount of air to pass through, thus ensuring that the air in the first spray treatment chamber 1 or the second spray treatment chamber 2 remains in a flowing state. At the same time, the other set of rotating ball valves 12 releases the basic closure of the corresponding exhaust pipe 4, and the air in the first spray treatment chamber 1 or the second spray treatment chamber 2 is discharged outwards. This allows the two sets of exhaust pipes 4 to be intermittently kept fully open or basically closed, so that the air can stay in the first spray treatment chamber 1 or the second spray treatment chamber 2 for a sufficient period of time before being discharged outwards, thereby increasing the spraying effect.

[0049] The first spray treatment chamber 1 is equipped with a drive mechanism for driving the rotating shaft 9 to rotate. The drive mechanism includes a motor 16, which is installed on the side of the first spray treatment chamber 1 near the exhaust pipe 4. The output end of the motor 16 is connected to a reciprocating lead screw 17, and an incomplete rack 18 is sleeved on the outside of the reciprocating lead screw 17. Limit rods 19 are installed on both sides of the incomplete rack 18 near the rotating shaft 9. A guide rod 20 passes through one side of the incomplete rack 18, and the guide rod 20 is fixedly connected to the first spray treatment chamber 1.

[0050] The incomplete rack 18 is threadedly connected to the reciprocating screw 17, and the incomplete rack 18 is slidably connected to the guide rod 20. This means that when the reciprocating screw 17 rotates, the rotation of the incomplete rack 18 is restricted by the guide rod 20, thereby allowing the incomplete rack 18 to move laterally back and forth continuously.

[0051] The incomplete rack 18 has a toothed block at the middle position of only one end. When the incomplete rack 18 moves laterally to a position close to the middle, it can drive the rotating shaft 9 to rotate 90°, thereby changing the opening and closing states of the two sets of rotating ball valves 12, thus completing the above-mentioned engagement operation. After driving the rotating shaft 9 to rotate 90°, the incomplete rack 18 will continue to move a certain distance. During this distance, the incomplete rack 18 disengages from the first gear 10, but the corresponding limit rod 19 begins to insert into the limit through hole 11. Thus, during this distance, the rotating shaft 9 will not rotate and will be restricted by the limit rod 19, remaining at the adjusted angle. Therefore, during the entire stroke of the incomplete rack 18, the rotating shaft 9 always rotates 90° and stabilizes for a period of time, then rotates 90° in the opposite direction and continues to stabilize for a period of time.

[0052] During the above process, the two sets of rotating ball valves 12 perform the same action as the rotating shaft 9. Therefore, the two sets of rotating ball valves 12 can intermittently open or basically close the corresponding exhaust pipe 4, and will remain in the open or basically closed state for a certain period of time.

[0053] Example 2

[0054] Based on the above embodiment 1, see Figures 5-6 as well as Figure 10 As shown, an arc-shaped extrusion block 15 is installed on the outer wall of the rotating ball valve 12 near the first spray treatment chamber 1. An installation chamber 21 is installed on the top of the atomizing water distributor 28. An active mechanism for blocking the air in the first spray treatment chamber 1 and the second spray treatment chamber 2 is provided in the installation chamber 21. The active mechanism includes a rack body 22, which is located inside the installation chamber 21. A spring 23 is connected between the rack body 22 and the installation chamber 21. A movable extrusion rod 24 is installed on the side of the rack body 22 near the exhaust pipe 4. The movable extrusion rod 24 extends through the installation chamber 21 into the interior of the exhaust pipe 4. The movable extrusion rod 24 is slidably connected to the installation chamber 21, and the movable extrusion rod 24 and the rack body 22 are integrally manufactured.

[0055] When a set of rotating ball valves 12 rotates to a state that is basically closed to the corresponding exhaust pipe 4, the arc-shaped extrusion block 15 on the rotating ball valve 12 will extrude the corresponding movable extrusion rod 24, thereby causing the rack body 22 to move laterally accordingly, and the spring 23 to be compressed accordingly.

[0056] The mechanism also includes a rotating wind deflector 25, which is evenly distributed throughout the bottom of the installation chamber 21 and extends through the atomizing water distributor 28. A second gear 26 is installed on the top of the rotating wind deflector 25. The central axis of the rotating wind deflector 25 is perpendicular to the transverse central axis of the installation chamber 21. The rotating wind deflector 25 is rotatably connected to both the installation chamber 21 and the atomizing water distributor 28, so that the rotating wind deflector 25 can rotate under the action of a corresponding external force.

[0057] Furthermore, fan blades are provided on both sides of the outer wall of the rotating wind deflector 25. In the initial state, the rotating wind deflector 25 is parallel to the direction of airflow in the first spray treatment chamber 1 and the second spray treatment chamber 2. This ensures that the rotating wind deflector 25 does not obstruct the airflow too much in the initial state, thus ensuring the normal passage of the airflow. However, when the rotating wind deflector 25 rotates at a certain angle, the fan blades on the rotating wind deflector 25 form a certain angle with the direction of airflow. This causes the air to be blocked to a certain extent by the fan blades during passage, thereby reducing the air velocity and allowing the air to come into more full contact with the spray liquid, thereby increasing the treatment effect.

[0058] The central axis of the second gear 26 is perpendicular to the transverse central axis of the rack body 22, and the second gear 26 is meshed with the rack body 22. When the arc-shaped extrusion block 15 rotates to face the first spray treatment chamber 1 and is squeezed by the corresponding movable extrusion rod 24 to drive the rack body 22 to move laterally, the corresponding multiple sets of rotating wind deflectors 25 can rotate to a certain extent, thereby completing the above-mentioned task of partially blocking the air. The rotation amplitude of the rotating wind deflector 25 is less than 90°, and the rotating wind deflector 25 always rotates when the corresponding rotating ball valve 12 has basically closed the corresponding exhaust pipe 4.

[0059] Example 3

[0060] Based on the above embodiment 1, see Figures 1-2 As shown, a connecting rope 7 is connected to the outer side of the air inlet pipe 3 away from the multi-way connecting pipe 27, and a dust detector 8 is connected to the end of the connecting rope 7 away from the air inlet pipe 3. The dust detector 8 is the same as the existing air dust content detection equipment, and the connecting rope 7 is of fixed length.

[0061] After the air inlet pipe 3 is installed at the inlet and outlet of the manufactured sand equipment, the dust detector 8 is moved to a designated distance away and the dust content in the air at that location is monitored in real time. When the dust content is found to be excessive, the power of the exhaust mechanism connected to the negative pressure extraction pipe 5 can be increased, and the power of the spray liquid supply equipment connected to the atomizing water distributor 28 can also be increased, thereby increasing the negative pressure adsorption force and spraying effect to ensure the final dust removal effect.

[0062] The working principle of this invention is as follows: the negative pressure extraction pipe 5 is connected to the exhaust equipment, the atomizing water distributor 28 is connected to the spray liquid supply equipment, the bottom of the first spray treatment chamber 1 and the second spray treatment chamber 2 are respectively connected to the spray liquid collection equipment, the two sets of air inlet pipes 3 are respectively installed near the feed port and discharge port of the manufactured sand equipment, and the corresponding dust detectors 8 are respectively installed at a specified distance from the corresponding air inlet pipe 3.

[0063] When the above equipment is turned on, the exhaust system draws air and dust from near the inlet and outlet of the manufactured sand equipment into the inlet pipe 3, and then through the multi-connector pipe 27, the first spray treatment chamber 1, the second spray treatment chamber 2, the exhaust pipe 4, and the negative pressure extraction pipe 5, and finally out through the exhaust system. During this process, the air can be sprayed by the spray liquid sprayed by the atomizing water distributor 28 when it enters the first spray treatment chamber 1 and the second spray treatment chamber 2. At the same time, the dust detector 8 can detect the dust content near the inlet and outlet. When the dust content is too high, the operator can increase the power of the exhaust system connected to the negative pressure extraction pipe 5, thereby increasing the adsorption force at the opening of the inlet pipe 3, and at the same time increasing the power of the spray liquid supply equipment connected to the atomizing water distributor 28, thereby increasing the total amount and rate of spraying, and thus ensuring the treatment effect.

[0064] During the above process, the motor 16 is turned on, and the motor 16 drives the reciprocating screw 17 to rotate continuously. The incomplete rack 18 is threadedly connected to the reciprocating screw 17, and the incomplete rack 18 is slidably connected to the guide rod 20, so that the incomplete rack 18 can move laterally back and forth continuously. As mentioned above, the lateral reciprocating movement of the incomplete rack 18 can drive the rotating shaft 9 to rotate intermittently to 90°, and it will stay for a period of time after each rotation. This allows the two sets of rotating ball valves 12 to open or basically close the corresponding exhaust pipes 4 intermittently, and the opening and basically closing states of the two sets of exhaust pipes 4 are always opposite.

[0065] When a set of exhaust pipes 4 is in a basically closed state, the air in the corresponding first spray treatment chamber 1 or second spray treatment chamber 2 will significantly reduce its flow rate, thereby accumulating in the first spray treatment chamber 1 or second spray treatment chamber 2 and fully contacting the spray liquid. When a set of exhaust pipes 4 changes from a basically closed state to a fully open state, the other set of exhaust pipes 4 will change to the opposite state at this time, and the pressure in the corresponding first spray treatment chamber 1 or second spray treatment chamber 2 will increase due to the previous closed state. At this time, the fully sprayed air can be discharged with the subsequently entering air, and the above process will be repeated continuously, thereby increasing the spray treatment effect.

[0066] Furthermore, when a set of rotating ball valves 12 rotates to basically close the corresponding exhaust pipe 4, the arc-shaped extrusion block 15 on it will press against the corresponding movable extrusion rod 24, causing the corresponding rack body 22 to move laterally, thereby causing the corresponding multiple sets of rotating wind deflectors 25 to rotate to a certain extent and form a certain angle with the air passage direction, thereby further reducing the air flow rate in the first spray treatment chamber 1 or the second spray treatment chamber 2 in this state, ensuring the spraying effect.

[0067] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
