[0002] With the continuous acceleration of urbanization, more and more modern buildings appear 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, there is gradually an emergence of machine-made sand that uses corresponding raw materials and equipment for crushing. In the process of machine-made sand production, dust is one of the main factors affecting the on-site working environment. Therefore, in the process of machine-made sand production, it is generally necessary to equip the corresponding automatic dust removal system for the machine-made sand production process;

However, in actual application, there is a problem that the dust-containing air is easy to flow too fast in the spray part, resulting in insufficient contact with the spray liquid, which in turn causes the spray liquid to fail to properly treat the dust-containing air.

[0021] Beneficial effects of the present invention:

[0022] (1) The present invention provides two sets of rotating ball valves on the rotating shaft, one end of the rotating ball valve is provided with a large-diameter main through hole, and the two sets of large-diameter main through holes are oriented in different directions, and the first spray treatment chamber is provided with a driving mechanism for driving the rotating shaft to rotate, so that during use, the two sets of exhaust pipes can be intermittently opened and closed, and the opening and closing states of the two sets of exhaust pipes are always opposite, so that 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 provides a small-diameter secondary through hole on the rotating ball valve, and the small-diameter secondary through hole is in the opposite direction to the large-diameter main through hole on the same set of rotating ball valves, so that after the rotating ball valve is rotated and closed, the exhaust pipe is not completely closed, and a small amount of air can be discharged outward through the small-diameter secondary through hole, so that the air in the first spray treatment chamber and the second spray treatment chamber has a basic flow direction, so as to cooperate to complete the spraying work while avoiding the phenomenon of backflow and the like;

[0024] (3) The present invention provides an arc-shaped extrusion block on the rotating ball valve, and the second gear is meshed with the rack body, so that when the rotating ball valve is rotated to close the exhaust pipe, only a small-diameter auxiliary hole is used to exhaust a small amount of air, so that the first spray treatment chamber or the second spray treatment chamber maintains basic air circulation to cooperate with spraying. The arc-shaped extrusion block will squeeze the corresponding movable extrusion rod to rotate the corresponding rotating wind shield, so that the fan blades on the rotating wind shield form a certain angle with the air flow direction, thereby increasing the friction and blocking ability of the air, and further reducing the air flow rate without hindering the air flow, thereby further ensuring the spraying effect;

[0025] (4) The present invention provides a connecting rope and a dust detector on the air inlet pipe, so that after the staff aligns one end of the two groups of air inlet pipes away from the multi-way connecting pipe near the machine-made sand inlet and outlet, the dust detector can be further placed and installed at a position 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, thereby ensuring the dust removal effect through monitoring and adjustment.

DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] Embodiment 1:

[0041] See also Figure 1-Figure 4 as well as Figure 7-Figure 9 as well as Fig.11 As shown, the present invention is an automatic dust removal system for a machine-made sand production process with an intelligent monitoring function, comprising a first spray processing chamber 1, a second spray processing chamber 2 is installed on the top of the first spray processing chamber 1, and atomizing water distributors 28 are installed on one side of the first spray processing chamber 1 and the second spray processing chamber 2, and a multi-way connecting pipe 27 is connected to the side of the first spray processing chamber 1 and the second spray processing chamber 2 close to the atomizing water distributor 28, and the end of the multi-way connecting pipe 27 away from the first spray processing chamber 1 is connected to two groups of air inlet pipes 3;

[0042] During use, the air inlet pipe 3 can be an elastic bellows, and 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 impurities with larger particles, and the air inlet pipe 3 is pulled and fixed to the vicinity of the feed port and discharge port of the machine-made sand equipment away from the opening of the multi-way connecting pipe 27. At the same time, the atomizing water distributor 28 is connected to the spray liquid supply equipment, and the two groups of atomizing water distributors 28 basically seal the interior of the first spray treatment bin 1 and the second spray treatment bin 2 respectively, and only the part away from the multi-way connecting pipe 27 can be used for air to pass. Therefore, when the dust-laden air enters the first spray treatment bin 1 and the second spray treatment bin 2 through the air inlet pipe 3 and the multi-way connecting pipe 27, it can only pass through the lower space in the first spray treatment bin 1 and the second spray treatment bin 2, thereby ensuring that the atomizing water distributor 28 can perform the spraying task on the air.

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

[0044] The negative pressure extraction pipe 5 is connected to the exhaust device, and the exhaust device has a wind force adjustment function. When the exhaust device is running, it can drive external air to enter through the air inlet pipe 3, and pass 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 be discharged through the exhaust device. In this process, the air can be sprayed when passing 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 duct 4, and a first gear 10 is installed on the outer side of the rotating shaft 9. A limiting through hole 11 is provided 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 duct 4, and the rotating shaft 9 and the exhaust duct 4 are rotatably connected, so that under the action of corresponding external force, the rotating shaft 9 can rotate accordingly.

[0046] A rotating ball valve 12 is installed at both ends of the rotating shaft 9. A large-diameter main through hole 13 is opened at one end of the outer wall of the rotating ball valve 12, and small-diameter secondary through 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 groups of rotating ball valves 12 face oppositely, the small-diameter secondary through holes 14 on the two groups of rotating ball valves 12 face oppositely, the large-diameter main through holes 13 and the small-diameter secondary through holes 14 on the same group of rotating ball valves 12 face oppositely, and the inner diameter of the large-diameter main through holes 13 is much larger than the inner diameter of the small-diameter secondary through holes 14;

[0048] When the rotating shaft 9 rotates, one group of rotating ball valves 12 can complete the basic closure of the corresponding exhaust pipe 4, and only the small-diameter auxiliary through hole 14 is left to allow a small amount of air to pass through, thereby ensuring that the air in the first spray treatment chamber 1 or the second spray treatment chamber 2 remains in a flowing state, and the other group of rotating ball valves 12 in this state 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 outward, so that the two groups of exhaust pipes 4 can 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 period of time before being discharged outward, thereby increasing the spraying effect.

[0049] The first spray treatment chamber 1 is provided with a driving mechanism for driving the rotating shaft 9 to rotate, and the driving mechanism includes a motor 16, which is installed on the side of the first spray treatment chamber 1 close to the exhaust pipe 4, and the output end of the motor 16 is connected to a reciprocating screw 17, and the outer side of the reciprocating screw 17 is sleeved with an incomplete rack 18, and both sides of the incomplete rack 18 close to one end of the rotating shaft 9 are equipped with limit rods 19, and a guide rod 20 is passed 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, so that when the reciprocating screw 17 rotates, the rotation of the incomplete rack 18 is restricted by the guide rod 20, so that the incomplete rack 18 can continuously move back and forth laterally;

[0051] The incomplete rack 18 is provided with a tooth block only at the middle position of one end. When the incomplete rack 18 moves back and forth laterally to a position close to the middle, the incomplete rack 18 can drive the rotating shaft 9 to rotate 90°, thereby causing the two sets of rotating ball valves 12 to change the open and closed states respectively, thereby completing the above-mentioned matching operation. At the same time, the incomplete rack 18 will continue to move a certain stroke after driving the rotating shaft 9 to rotate 90°. During this stroke, the incomplete rack 18 is released from meshing with the first gear 10, but the corresponding limit rod 19 begins to be inserted into the limit through hole 11, so that during this stroke, the rotating shaft 9 will not rotate, and is limited by the limit rod 19 and remains at the adjusted angle. Therefore, during the entire stroke of the incomplete rack 18, the rotating shaft 9 always rotates 90° and then stabilizes for a period of time, and then rotates 90° in the opposite direction and continues to stabilize for a period of time;

[0052] In the above process, the two sets of rotating ball valves 12 perform the same action with the rotating shaft 9, so the two sets of rotating ball valves 12 can intermittently open or basically close the corresponding exhaust pipes 4, and will stay in the open or basically closed state for a certain period of time.

[0053] Example 2

[0054] Based on the above embodiment 1, refer to Figure 5-Figure 6 as well as Fig.10 As shown, an arc-shaped extrusion block 15 is installed on the side of the outer wall of the rotating ball valve 12 close to the first spray treatment chamber 1, and a mounting chamber 21 is installed on the top of the atomizing water distributor 28. A movable mechanism for blocking the air in the first spray treatment chamber 1 and the second spray treatment chamber 2 is arranged in the mounting chamber 21. The movable mechanism includes a rack body 22, and the rack body 22 is arranged inside the mounting chamber 21. A spring 23 is connected between the rack body 22 and the mounting chamber 21. A movable extrusion rod 24 is installed on the side of the rack body 22 close to the exhaust pipe 4, and the movable extrusion rod 24 penetrates the mounting chamber 21 and extends to the inside of the exhaust pipe 4. The movable extrusion rod 24 is slidably connected to the mounting chamber 21, and the movable extrusion rod 24 and the rack body 22 are made as an integrated whole;

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

[0056] The movable mechanism also includes a rotating windshield 25, which is uniformly penetrated through the bottom of the installation bin 21, and the rotating windshield 25 penetrates the atomizing water distributor 28, and a second gear 26 is installed on the top of the rotating windshield 25, the central axis of the rotating windshield 25 is perpendicular to the transverse central axis of the installation bin 21, and the rotating windshield 25 is rotatably connected to the installation bin 21 and the atomizing water distributor 28, so that the rotating windshield 25 can rotate accordingly 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 shield 25, and in the initial state, the rotating wind shield 25 is parallel to the traveling direction of the airflow in the first spray treatment chamber 1 and the second spray treatment chamber 2, so that in the initial state, the rotating wind shield 25 does not cause too much obstruction to the airflow, ensuring the normal passage of the airflow. However, when the rotating wind shield 25 rotates a certain angle, the fan blade part on the rotating wind shield 25 forms a certain angle with the passing direction of the airflow, so that the air is blocked by the fan blade part to a certain extent during the passage process, thereby reducing the flow rate of the air, so that the air can be more fully in 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 meshingly connected to the rack body 22, so that when the arc-shaped extrusion block 15 rotates to the direction toward the first spray treatment chamber 1 and squeezes the corresponding movable extrusion rod 24 to drive the rack body 22 to move laterally, the corresponding multiple groups of rotating wind shields 25 can rotate to a certain extent, thereby completing the above-mentioned partial blocking task of the air, and the rotation amplitude of the rotating wind shield 25 is less than 90°, and the rotating wind shield 25 always rotates when the corresponding rotating ball valve 12 completes the basic closure of the corresponding exhaust pipe 4.

[0059] Example 3

[0060] Based on the above embodiment 1, refer to Figure 1-Figure 2 As shown, a connecting rope 7 is connected to the outer side of one end 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 dust content detection equipment in the air, and the connecting rope 7 is of a fixed length;

[0061] After the air inlet pipe 3 is installed at the inlet and outlet of the machine-made sand equipment, the dust detector 8 is moved to a position at a specified distance from the location, and the dust content in the air at the location is monitored in real time. When the staff finds that the dust content exceeds the standard, the power of the exhaust mechanism connected to the negative pressure extraction pipe 5 can be increased, and at the same time, the power of the spray liquid supply device connected to the atomizing water distributor 28 can be increased, thereby increasing the negative pressure adsorption force and the spraying effect to ensure the final dust removal effect.

[0062] The working principle of the present invention is as follows: the negative pressure extraction pipe 5 is connected to the exhaust device, the atomizing water distributor 28 is connected to the spray liquid supply device, the bottoms of the first spray processing bin 1 and the second spray processing bin 2 are respectively connected to the spray liquid collection device, the two sets of air inlet pipes 3 are respectively installed near the feeding port and the discharging port of the machine-made sand equipment, and the corresponding dust detectors 8 are respectively installed at the positions of the specified distances from the corresponding air inlet pipes 3;

[0063] Turn on the above equipment, and the exhaust equipment drives the air and dust near the inlet and outlet of the machine-made sand equipment into the air inlet pipe 3, and passes through the multi-way connecting pipe 27, and then passes through 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 is finally discharged through the exhaust equipment. In this process, the air can be sprayed with the spray liquid sprayed by the atomizer 28 when passing through 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 staff can increase the power of the exhaust equipment connected to the negative pressure extraction pipe 5, thereby increasing the adsorption force at the opening of the air inlet pipe 3, and at the same time increase the power of the spray liquid supply equipment connected to the atomizer 28, thereby increasing the total amount and rate of spraying, thereby ensuring the treatment effect;

[0064] In the above process, the motor 16 is turned on, and the motor 16 drives the reciprocating screw 17 to rotate continuously. Through the threaded connection between the incomplete rack 18 and the reciprocating screw 17, and the sliding connection between the incomplete rack 18 and the guide rod 20, the incomplete rack 18 can continuously move back and forth laterally. 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, so that the two sets of rotating ball valves 12 can intermittently open or basically close the corresponding exhaust pipes 4, and the opening and basically closing states of the two sets of exhaust pipes 4 are always opposite;

[0065] When one group 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 significantly reduces its flow rate, so that the air stays and accumulates in the first spray treatment chamber 1 or the second spray treatment chamber 2 and fully contacts with the spray liquid. When one group of exhaust pipes 4 is converted from a basically closed state to a fully open state, since the other group of exhaust pipes 4 is converted into the opposite state at this time, and the pressure in the corresponding first spray treatment chamber 1 or the second spray treatment chamber 2 increases due to the previous closed state, the air that has been fully sprayed can be discharged first with the subsequent air, and the above process is repeated continuously, thereby increasing the spray treatment effect;

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

[0067] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
