Description

Technical Field

[0001] This utility model relates to the field of dry-mixed mortar production technology, specifically to a packaging dust removal system and a mortar production line. Background Technology

[0002] The packaging section of a dry-mixed mortar production line involves the dispensing, metering, sealing, transfer, palletizing, and loading of the uniformly mixed dry mortar into trucks. This process is highly prone to generating dust, making it a significant dust-generating stage. Dust pollution pollutes the environment, harms the health of packaging operators, worsens the environmental conditions of packaging equipment, affects its normal operation, reduces its lifespan, and increases maintenance costs. The dust concentration at a monitoring point a certain distance from the packaging equipment is a key indicator of environmental performance.

[0003] Traditional packaging dust collectors typically use a combination of a top-mounted dust collection hood and a bag filter. This combination results in relatively weak suction, a large open area, and a tendency for dust to settle and spill over. Utility Model Content

[0004] This utility model provides a packaging dust removal system and a mortar production line to solve the technical problems in the prior art.

[0005] To solve the above problems, the packaging dust removal system provided by this utility model adopts the following technical solution: it includes a wrap-around storage chamber, which is set at the bottom of the packaging system, and the wrap-around storage chamber is used to collect the dust generated by the packaging system;

[0006] A ground-level grid is installed at the top opening of a wrap-around ground-level enclosure. The ground-level grid is used to control the opening and closing of the wrap-around ground-level enclosure. The ground-level grid includes several rotating strips rotatably mounted on the top of the wrap-around ground-level enclosure. The rotating strips are connected to a linkage mechanism on their sides for driving the rotating strips to rotate. The linkage mechanism is connected to a drive mechanism for driving the linkage mechanism to move.

[0007] The rotating slats have an open position and a sealed position during their rotation stroke. When the rotating slats are in the open position, they are in an inclined or vertical state, and there are gaps between the rotating slats, allowing dust to enter the underground grid through the gaps between the rotating slats. When the rotating slats are in the sealed position, they are in a horizontal state, and adjacent rotating slats are fitted together to prevent secondary dust overflow.

[0008] Pulse jet dust collector: The pulse jet dust collector is connected to the bottom of the enclosed underground chamber through a pipe. The pulse jet dust collector is used to remove dust inside the enclosed underground chamber.

[0009] A dust concentration meter is installed on the side of the packaging system to detect the dust content within the packaging system. The dust concentration meter is connected to an external control system.

[0010] As a further improvement, the enclosed storage chamber has a conical structure, with the top opening being larger than the bottom opening to facilitate dust collection.

[0011] As a further improvement, at least two of the enclosed underground bunkers are provided, and valves are installed at the bottom of the enclosed underground bunkers.

[0012] As a further improvement, the linkage mechanism includes a gear fixedly connected to a rotating slat, and a rack for driving the gear to rotate, the rack meshing with several gears.

[0013] As a further improvement, the packaging system is surrounded by a track with a traveling mechanism on it, and the dust concentration meter is fixedly mounted on the traveling mechanism, so that the dust concentration meter can be inspected along the track.

[0014] This utility model also provides a mortar production line, comprising:

[0015] Dry-mixed mortar production line; a dry-mixed mortar production line is used to process dry-mixed mortar.

[0016] Packaging system, used for packaging finished dry-mixed mortar;

[0017] The dry-mixed mortar production line and the packaging system are arranged in a vertical direction, with the packaging system located below the dry-mixed mortar production line.

[0018] It also includes a wrap-around storage unit, which is located at the bottom of the packaging system and is used to collect dust generated by the packaging system;

[0019] A ground-level grid is installed at the top opening of a wrap-around ground-level enclosure. The ground-level grid is used to control the opening and closing of the wrap-around ground-level enclosure. The ground-level grid includes several rotating strips rotatably mounted on the top of the wrap-around ground-level enclosure. The rotating strips are connected to a linkage mechanism on their sides for driving the rotating strips to rotate. The linkage mechanism is connected to a drive mechanism for driving the linkage mechanism to move.

[0020] The rotating slats have an open position and a sealed position during their rotation stroke. When the rotating slats are in the open position, they are in an inclined or vertical state, and there are gaps between the rotating slats, allowing dust to enter the underground grid through the gaps between the rotating slats. When the rotating slats are in the sealed position, they are in a horizontal state, and adjacent rotating slats are fitted together to prevent secondary dust overflow.

[0026] As a further improvement, the packaging system is surrounded by a track with a traveling mechanism on it, and the dust concentration meter is fixedly mounted on the traveling mechanism, so that the dust concentration meter can be inspected along the track.

[0027] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0028] 1. This utility model improves the traditional top-mounted dust collection hood into a wrap-around ground chamber, and sets a ground chamber grid on the top of the wrap-around ground chamber, which greatly reduces the problem of secondary dust overflow.

[0029] The structure of the enclosed dust collection chamber is similar to that of a traditional dust collection hood (vacuum hood), but in this invention, the enclosed dust collection chamber is located below the ground and beneath the packaging system. When absorbing dust, in addition to being adsorbed by the negative pressure of the pulse dust collector, the dust also settles through the chamber's grid and enters the enclosed dust collection chamber, thus improving the problem of limited suction power in existing vacuum hoods, which prevents dust from being absorbed quickly.

[0030] The ground grating plays a role in controlling the opening and closing of the enclosed ground grating. When the ground grating is open, due to the negative pressure and gravity of the pulse dust collector, the dust can only pass through the ground grating in one direction and enter the enclosed ground grating, thus preventing secondary dust overflow.

[0031] 2. The dust concentration measuring instrument of this utility model adopts the track inspection mode, which patrols according to the set trajectory, improves the monitoring range, solves the limitations of fixed-point detection, and helps to improve the dust removal effect.

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0041] In existing technologies, traditional packaging dust collectors typically use a combination of a top-mounted dust collection hood and a bag filter. This combination results in relatively weak suction, a large open area, and a tendency for dust to settle and spill over.

[0042] Dust generation is unavoidable during the packaging process. This dust not only pollutes the production environment but may also seep into the finished mortar, affecting its quality and performance.

[0043] Dust can be generated at any stage of the packaging process, especially during bagging. The design of the bagging of dry-mixed mortar and the removal of air from the bag can easily generate dust.

[0044] To address the aforementioned issues, this invention improves the structure of the dust removal system by placing the enclosed storage chamber below the packaging system. During dust absorption, in addition to being adsorbed by the negative pressure of the pulse dust collector, the dust also settles through the chamber's grid and enters the enclosed storage chamber. This improves upon the limited suction power of existing dust hoods and avoids the problem of some dust easily settling to the ground, resulting in excessive dust on the ground.

[0045] The ground grating plays a role in controlling the opening and closing of the enclosed ground grating. When the ground grating is open, due to the negative pressure and gravity of the pulse dust collector, the dust can only pass through the ground grating in one direction and enter the enclosed ground grating, thus preventing secondary dust overflow.

[0046] At least two enclosed dust collection chambers are provided. On the one hand, this allows the dust collection system to operate intermittently in rotation. That is, when the grid of one chamber is open to collect dust, the grid of the other chamber is closed to discharge the dust remaining in the enclosed chamber. The two chambers operate intermittently in rotation. On the other hand, this also improves the stability of the equipment and prevents the dust collection system from failing if one of the enclosed chambers malfunctions.

[0047] This dust removal system ensures that dust is properly disposed of and will not cause secondary pollution to the environment. At the same time, it further guarantees the quality and stability of the finished mortar.

[0048] After introducing the basic principles of this utility model, various non-limiting embodiments of this utility model are described in detail below. Any quantity of elements in the accompanying drawings is for illustrative purposes only and not for limitation, and any naming is for distinction only and has no limiting meaning.

[0049] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0050] Example 1 of the packaging dust removal system and mortar production line provided by this utility model:

[0051] like Figures 1-4 As shown, the packaging dust removal system includes a wrap-type silo 4, a silo grid 7 installed on top of the wrap-type silo 4, a pulse dust collector 2 connected to the bottom of the wrap-type silo 4 for dust removal, and a dust concentration meter 6 for detecting dust concentration.

[0052] like Figures 1-3 As shown, the enclosed storage chamber 4 is mainly used to collect dust generated by the dry-mixed mortar production line 1 or the packaging system 3. The enclosed storage chamber 4 is set at the bottom of the packaging system 3. In this embodiment, a pit is dug at the bottom of the packaging system 3 and the enclosed storage chamber 4 is installed in the pit. The enclosed storage chamber 4 has a conical or funnel-shaped structure. The top opening of the enclosed storage chamber 4 is larger than the bottom opening to collect dust. A valve 5 is installed at the bottom of the enclosed storage chamber 4. The valve 5 is an electric or pneumatic valve 5 so that it can be controlled to open and close by an external control system and is linked with the storage chamber grid 7. In this embodiment, the enclosed storage chamber 4 has six compartments, and there are six corresponding storage chamber grids 7, valves 5 and other components.

[0053] like Figure 4As shown, the basement grille 7 is installed at the top opening of the enclosed basement 4. The basement grille 7 is used to control the opening and closing of the enclosed basement 4. The basement grille 7 includes several rotating slats 73 rotatably mounted on the top of the enclosed basement 4. In this embodiment, the top of the enclosed basement 4 is provided with a frame 74. The rotating slats 73 are rotatably mounted in the frame 74. The side of the rotating slats 73 is connected to a linkage mechanism 72 for driving the rotating slats 73 to rotate. The linkage mechanism 72 is connected to a drive mechanism 71 for driving the linkage mechanism 72 to move. The structure of the basement grille 7 is similar to a louver.

[0054] The rotating slats 73 have an open position and a sealed position during their rotation stroke. When the rotating slats 73 are in the open position, they are either in an inclined or vertical state, and there are gaps between the rotating slats 73, allowing dust to enter the underground grid 7 through the gaps between the rotating slats 73. When the rotating slats 73 are in the sealed position, they are in a horizontal state, and adjacent rotating slats 73 are pressed together to prevent secondary dust overflow.

[0055] In this embodiment, the linkage mechanism 72 includes a gear fixedly connected to the rotating slat 73, and a rack for driving the gear to rotate, the rack meshing with several gears. The drive mechanism 71 controls the rotating slat 73 by driving the rack to reciprocate, thereby controlling the opening and closing of the basement grille 7. The drive mechanism 71 can be a pneumatic or electric telescopic mechanism, such as a cylinder or electric cylinder.

[0056] There are relatively many structures for the linkage mechanism 72; either a pneumatic or electric structure can be selected.

[0057] The pulse dust collector 2 is connected to the bottom of the enclosed underground chamber 4 through a pipe. The pulse dust collector 2 is used to remove dust inside the enclosed underground chamber 4. The pulse dust collector 2 is existing technology, and its structure has not been improved in this utility model. Its structure will not be described in detail here.

[0058] The dust concentration meter 6 is installed on the side of the packaging system 3 to detect the dust content inside the packaging system 3. The dust concentration meter 6 is connected to the external control system.

[0059] The packaging system 3 is surrounded by a track (not shown in the figure), on which a traveling mechanism is installed. The dust concentration meter 6 is fixedly mounted on the traveling mechanism, allowing the dust concentration meter 6 to perform inspections along the track. The track and traveling mechanism are existing technologies, and their structures will not be described in detail here.

[0060] This embodiment also provides a mortar production line, including:

[0061] Dry-mixed mortar production line 1 is used to process dry-mixed mortar. It includes equipment for raw material preparation (manufactured sand production, natural sand drying), screening equipment, storage silos of various specifications, metering equipment, high-efficiency mixers, packaging equipment, and dust removal equipment. The high-efficiency mixer is responsible for thoroughly mixing the raw materials to form a high-quality dry-mixed mortar mixture. The electrical control cabinet and control system are the command center of the entire production line, precisely coordinating and controlling the operation of each piece of equipment.

[0062] Raw materials, including sand, cement, fly ash, and admixtures, are prepared according to strict formula requirements. Natural or manufactured sand is finely screened to obtain a particle size distribution that meets production standards. Metering equipment accurately measures the proportions of each raw material to ensure accurate batching. The components are fed into a mixer and thoroughly mixed to form a homogeneous mortar mixture. After careful packaging, the finished mortar is stored in a finished product warehouse, awaiting subsequent transportation and use.

[0063] Packaging system 3 is used to package the finished dry-mixed mortar. In this embodiment, both packaging system 3 and the above-mentioned dry-mixed mortar production line 1 adopt a container design, which facilitates transportation and installation.

[0064] After precise measurement and efficient mixing, qualified dry-mixed mortar is discharged from the screw conveyor or directly into the packaging hopper, packaged into bags by multiple packaging machines, and then packaged by belt conveyor, palletizer and wrapping machine. Finally, it is transported by forklift to the warehouse and stacked in an orderly manner.

[0065] The pulse dust collector 2 and dust concentration meter 6 described below in the dry-mixed mortar production line 1 and packaging system 3 are all existing technologies, and the structure of the above devices has not been improved in this embodiment. The structure of the dry-mixed mortar production line 1, packaging system 3, pulse dust collector 2 and dust concentration meter 6 will not be described in detail here.

[0066] The dry-mixed mortar production line 1 and the packaging system 3 are arranged in a vertical direction, with the packaging system 3 located below the dry-mixed mortar production line 1.

[0067] It also includes a wrap-around storage compartment 4, which is located at the bottom of the packaging system 3 and is used to collect dust generated by the packaging system 3;

[0068] The enclosed underground chamber 4 has a conical structure, with the top opening larger than the bottom to facilitate dust collection. At least two enclosed underground chambers 4 are provided, and valves 5 are installed at the bottom of each chamber.

[0069] The ground compartment grille 7 is installed at the top opening of the enclosed ground compartment 4. The ground compartment grille 7 is used to control the opening and closing of the enclosed ground compartment 4. The ground compartment grille 7 includes several rotating strips 73 rotatably mounted on the top of the enclosed ground compartment 4. The rotating strips 73 are connected to the side of a linkage mechanism 72 for driving the rotating strips 73 to rotate. The linkage mechanism 72 is connected to a drive mechanism 71 for driving the linkage mechanism 72 to move.

[0070] The rotating slats 73 have an open position and a sealed position during their rotation stroke. When the rotating slats 73 are in the open position, they are either in an inclined or vertical state, and there are gaps between the rotating slats 73, allowing dust to enter the underground grid 7 through the gaps between the rotating slats 73. When the rotating slats 73 are in the sealed position, they are in a horizontal state, and adjacent rotating slats 73 are pressed together to prevent secondary dust overflow.

[0071] The linkage mechanism 72 includes a gear fixedly connected to the rotating plate 73, and a rack for driving the gear to rotate, the rack meshing with several gears.

[0072] Pulse dust collector 2 is connected to the bottom of the enclosed underground chamber 4 through a pipe. The pulse dust collector 2 is used to remove dust inside the enclosed underground chamber 4.

[0073] The dust concentration meter 6 is installed on the side of the packaging system 3 to detect the dust content inside the packaging system 3. The dust concentration meter 6 is connected to the external control system.

[0074] The packaging system 3 has a track surrounding it, with a traveling mechanism on the track. The dust concentration meter 6 is fixedly mounted on the traveling mechanism, allowing the dust concentration meter 6 to perform inspections along the track. In this embodiment, the packaging system 3 adopts a container-type design, so the track can be installed on the inner wall of the container. In other embodiments, the arrangement of the track can be adjusted according to the layout of the packaging equipment.

[0075] Example 2 of the packaging dust removal system and mortar production line provided by this utility model:

[0076] Its main difference from Example 1 is:

[0077] like Figure 5 As shown, in this embodiment, the intelligent control system uses self-learning optimization (artificial intelligence) to select the optimal parameters (such as delay, lead time, air volume, speed, etc.), and then the intelligent control system optimizes the data based on historical data and target data.

[0078] Specifically, after the dust concentration meter data is uploaded to the external control system, if it exceeds the environmental protection limit, the bottom valve and the ground grid of the silo will be opened, and the packaging dust removal system will be started at the same time. Various control parameters will be automatically optimized to the best mode based on the data of the dust concentration meter, the difference between the data and the environmental protection limit, as well as the opening and closing degree of the ground grids and valves, and the air volume and speed of the dust collector.

[0079] Meanwhile, the dust concentration meter automatically inspects the measurement positions according to a certain trajectory and track.

[0080] The pulse dust collector can be automatically optimized by an external intelligent control system based on background data, historical data, and target data, according to the optimization of various parameters.

[0081] Example 3 of the packaging dust removal system and mortar production line provided by this utility model:

[0082] Its main difference from Example 1 is:

[0083] In this embodiment, the discharge port of the pulse dust collector is connected to the feeding mechanism of the dry-mixed mortar production line, allowing the dust to be reused. Since the dust inside the pulse dust collector is not affected by external pollution and is relatively clean, the recovered dust can be added during the batching process, reducing subsequent dust handling steps.

[0084] While this specification has shown and described numerous embodiments of the present invention, it will be apparent to those skilled in the art that such embodiments are provided by way of example only. Many modifications, alterations, and alternatives will occur to those skilled in the art without departing from the spirit and intent of the present invention. It should be understood that various alternatives to the embodiments of the present invention described herein may be employed in the practice of the present invention. The appended claims are intended to define the scope of protection of the present invention and therefore cover the modular compositions, equivalents, or alternatives within the scope of these claims.
