Description

Technical Field

[0001] The invention relates to the technical field of dust removal equipment, in particular to a gravity dust collector for the production of cast iron pipe fittings. Background Art

[0002] In the production process of cast iron pipe fittings, a large amount of waste gas containing dust will be generated. This dust will not only pollute the production environment and affect the health of workers, but also may damage the production equipment, reducing the service life and production efficiency of the equipment. Therefore, it is very important to effectively remove the dust generated in the production process of cast iron pipe fittings. Gravity dust collector, as a commonly used dust removal equipment, has been widely used in this field.

[0003] Existing gravity dust collectors for cast iron pipe production usually work based on the principle of gravity sedimentation, that is, after the dust-laden gas enters the dust collector, the gas flow rate decreases, and the dust particles gradually settle into the ash hopper under the action of gravity, thereby achieving the separation of gas and dust, so that the discharged gas reaches a certain cleanliness standard. Its general structure includes main components such as air inlet, dust collector body, ash hopper, and air outlet. The dust-laden gas enters the dust collector body from the air inlet, passes through the internal air flow channel or space, and the dust settles to the ash hopper under the action of gravity, and the purified gas is discharged from the air outlet.

[0004] However, the gravity dust collectors currently widely used in cast iron pipe production have obvious deficiencies in dust collection, which is specifically manifested in the inability to collect dust in different zones according to different particle sizes or densities, which has brought many adverse effects: The subsequent processing is inefficient; Dust of different particle sizes and densities often require different treatment methods in the subsequent processing stage. For example, dust of larger particle sizes may be relatively easy to clean and transport through simple mechanical conveying, while dust of smaller particle sizes may require more sophisticated collection equipment or special treatment processes (such as further screening, agglomeration, etc.) to prevent secondary dusting. Since existing gravity dust collectors cannot collect dust in different zones, all dust is mixed together, resulting in only a unified treatment method for subsequent treatment. This "one-size-fits-all" approach cannot meet the treatment needs of dust of different particle sizes and densities, which greatly reduces the efficiency of subsequent treatment.

[0005] Difficulty in recycling resources; In the production process of cast iron pipe fittings, the composition of dust is relatively complex, and the proportion of valuable components contained in dust of different particle sizes or densities may be different. For example, some larger dust particles may contain more recyclable metal particles (such as iron filings, etc.), while smaller dust particles may contain more impurities (such as sand particles, oxides, etc.). Existing gravity dust collectors cannot collect dust with different characteristics separately, making it difficult to effectively screen and extract valuable components in dust during resource recycling, reducing the resource recovery rate, increasing production costs, and not conducive to achieving energy conservation and emission reduction and effective utilization of resources.

[0006] Dust collector operation and maintenance issues; Increased risk of blockage: If dust of different particle sizes is mixed and accumulated in the same ash hopper, during the ash discharge process, the smaller dust particles are easy to fill in the gaps between larger particles, which may cause the ash discharge port to be blocked over time. Existing gravity dust collectors do not have the function of collecting dust in different areas, so this kind of blockage often occurs, which seriously affects the normal ash discharge function of the ash hopper, and may cause the overall operation of the dust collector to be unstable, requiring frequent shutdowns to clean blockages, reducing production efficiency.

[0007] Shortened equipment life: Dust of different particle sizes and densities wear the ash hopper to different degrees. Large dust particles have a larger mass and momentum, so they have a relatively strong impact and friction on the ash hopper wall during the falling process, which can easily cause wear on the ash hopper wall. As the existing dust collector cannot collect dust in different areas, it is impossible to take corresponding protective measures for dust with different characteristics, which affects the service life of the ash hopper and the entire dust collector, increasing the cost of equipment renewal and maintenance.

[0008] Inconvenient monitoring and management; Difficult to monitor accurately: It is impossible to collect dust of different particle sizes or densities in different areas, and it is difficult to monitor the dust accumulation, accumulation speed and other parameters in each area separately. This makes it difficult to accurately grasp the dust collection situation during the operation of the dust collector, and it is impossible to provide accurate data support for the operation adjustment of the dust collector (such as determining the appropriate cleaning time, discharge frequency, etc.), which is not conducive to the efficient operation of the dust collector.

[0009] Lack of targeted management: In terms of daily maintenance and management, the staff is unable to formulate more targeted management measures according to the different characteristics of dust. For example, for areas where high-concentration valuable dust is collected, stricter anti-theft and anti-leakage measures cannot be taken; for areas with fine dust that is prone to dust generation, sealing and ventilation management cannot be strengthened, which affects the management level and safety of the entire dust collector system.

[0010] To sum up, the existing gravity dust collector used in the production of cast iron pipe fittings has the defect that it cannot collect dust in different zones according to the different particle sizes or densities of the dust. This greatly limits its performance in dust removal effect, resource recycling, equipment operation and maintenance, monitoring and management in the production process of cast iron pipe fittings. Therefore, it is necessary to develop a gravity dust collector for the production of cast iron pipe fittings that can collect dust in different zones according to the different particle sizes or densities of the dust. Summary of the invention

[0011] The object of the present invention is to provide a gravity dust collector for the production of cast iron pipe fittings to solve the problems raised in the above background technology.

[0012] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a gravity dust collector for the production of cast iron pipe fittings, comprising a gravity dust collector, wherein pillars are installed on both sides of the bottom end of the gravity dust collector, and a first connecting pipe and a second connecting pipe are respectively arranged on the left and right sides of the gravity dust collector, and a first dust collecting chamber and a second dust collecting chamber are respectively opened on the left and right sides of the interior of the gravity dust collector, and ash discharge valves are respectively arranged on the left and right sides of the bottom end of the gravity dust collector, and the two ash discharge valves are respectively arranged below the first dust collecting chamber and the second dust collecting chamber, the inner cavity of the first dust collecting chamber is rotatably connected to a connecting rod through a bearing, a baffle is installed on the front side of the outer wall of the connecting rod, and a gear is installed on the rear side of the outer wall of the connecting rod, the bottom end of the inner cavity of the gravity dust collector is screwed with a cylinder, and a rack is installed on the output end of the upper surface of the cylinder, and the rack and the gear are meshed and connected with each other.

[0013] Preferably, a vibration motor is screwed to the bottom end of the inner cavity of the gravity dust collector, and an inspection door is provided at the center of the bottom end of the gravity dust collector, and the inspection door is located directly below the vibration motor.

[0014] Preferably, the baffle is located inside the first dust collecting chamber and the second dust collecting chamber.

[0015] Preferably, rubber sealing pads are symmetrically arranged on the left and right sides of the inner cavity of the gravity dust collector, and the rubber sealing pads match the baffles and their positions correspond to each other.

[0016] Preferably, a battery is built into the cylinder.

[0017] The invention provides a gravity dust collector for cast iron pipe production, which has the following beneficial effects: Through the cooperation among the gravity dust collector, the support, the first connecting pipe and the second connecting pipe, the dust generated in the process of cast iron processing can be conventionally removed. Through the cooperation among the connecting rod, the baffle, the gear, the cylinder and the rack, the dust settling space can be switched and adjusted according to the use requirements. The dust in the first dust collecting chamber or the second dust collecting chamber can be discharged through the dust discharge valve. The dust hanging on the wall can be shaken off by the vibration generated by the vibration motor to avoid the situation of blockage and failure of discharge. Designing the ash hopper into multiple compartments and collecting dust in different zones according to the different particle sizes or densities has the following important functions: Improve dust handling efficiency; Targeted treatment: Dust of different particle sizes or densities often requires different methods in the subsequent treatment process. For example, dust of larger particle sizes may be relatively easy to clean and transport through simple mechanical conveying, while dust of smaller particle sizes may require more sophisticated collection equipment or special treatment processes (such as further screening, agglomeration, etc.) to prevent secondary dusting. Through zoning collection, dust of different characteristics can be directly separated, so that the subsequent treatment of each part of the dust can be carried out more targeted, avoiding the problem of mismatch in treatment methods that may occur when all dust is treated uniformly, thereby improving the overall dust treatment efficiency.

[0018] Facilitate resource recycling; Composition difference: In the production process of cast iron pipe fittings, the composition of dust may be more complex, and the proportion of valuable components contained in dust of different particle sizes or densities may be different. For example, some larger dust particles may contain more recyclable metal particles (such as iron filings, etc.), while smaller dust particles may contain more impurities (such as sand particles, oxides, etc.). Through partitioned collection, it is more convenient to analyze and screen the dust collected in different compartments, and extract the dust containing valuable components separately for recycling, thereby improving the recovery rate of resources, reducing production costs, and achieving a certain degree of energy conservation and emission reduction.

[0019] Optimize dust collector operation; Prevent blockage: If dust of different particle sizes is mixed and accumulated in the same ash hopper, during the ash discharge process, the smaller dust particles are easy to fill in the gaps between larger particles, which may cause the ash discharge port to be blocked over time. Zoning collection allows each compartment to set a suitable ash discharge method and frequency according to the dust characteristics. For example, for fine-grained dust compartments that are prone to accumulation and blockage, the frequency of ash discharge can be increased or special anti-blocking devices (such as vibrators, etc.) can be used to effectively avoid the ash discharge port blockage caused by mixed dust accumulation, ensuring that the ash hopper can continuously and smoothly discharge dust and maintain the normal operation of the dust collector.

[0020] Extending equipment life: Dust of different particle sizes and densities wear the hopper to different degrees. Larger dust particles have a larger mass and momentum, so they have a relatively strong impact and friction on the hopper wall during the falling process, which can easily cause wear on the hopper wall. By collecting in different zones, more wear-resistant lining materials or enhanced structural designs can be used in easily worn compartments according to the dust characteristics of different compartments, thereby effectively extending the service life of the hopper and the entire dust collector.

[0021] Easy to monitor and manage; Accurate monitoring: Partitioned collection allows for individual monitoring of dust accumulation, accumulation speed and other parameters in each compartment. By installing corresponding sensors (such as material level sensors, etc.) in each compartment, the collection of dust with different characteristics can be more accurately understood, providing more accurate data support for dust collector operation adjustments (such as determining the appropriate cleaning time, dust discharge frequency, etc.).

[0022] Targeted management: In terms of daily maintenance and management, staff can formulate more targeted management measures based on the dust characteristics of different compartments. For example, for compartments that collect high-concentration valuable dust, more stringent anti-theft and anti-leakage measures are taken; for fine-grained dust compartments that are prone to dust, sealing and ventilation management are strengthened, thereby improving the management level and safety of the entire dust collector system.

[0027] As a preferred solution, further, a vibration motor 13 is screwed to the bottom end of the inner cavity of the gravity dust collector 1, and an inspection door 14 is provided at the center position of the bottom end of the gravity dust collector 1. The inspection door 14 is located directly below the vibration motor 13. The vibration generated by the vibration motor 13 can shake off the dust hanging on the wall to avoid blockage and non-discharge. The inspection door 14 is used for daily inspection and maintenance of the vibration motor 13.

[0028] As a preferred solution, further, the baffle 9 is located inside the first dust collecting chamber 5 and the second dust collecting chamber 6 .

[0029] As a preferred solution, further, rubber sealing pads are symmetrically arranged on the left and right sides of the inner cavity of the gravity dust collector 1, and the rubber sealing pads match the baffle 9 and the positions correspond to each other. The rubber sealing pads can improve the sealing between the baffle 9 and the inner wall of the dust collector.

[0030] As a preferred solution, further, a battery is built into the cylinder 11, and the battery can facilitate independent use of the cylinder 11 in special circumstances such as power outages.

[0031] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process. The specific work is as follows.

[0032] When in use, the air containing dust will enter the gravity dust collector 1 through the first connecting pipe 3 and be discharged through the second connecting pipe 4. During this process, the dust will undergo conventional sedimentation treatment in the gravity dust collector 1. This is a known technology and will not be described in detail here. The settled dust will move downward and fall on the baffle 9. The cylinder 11 is turned on, and the cylinder 11 will drive the rack 12 to move upward or downward. Since the rack 12 and the gear 10 are engaged with each other, when the rack 12 moves up and down, it can drive the gear 10 to drive the connecting rod 8 and the baffle 9 to rotate clockwise or counterclockwise, that is, when the settled dust has a larger particle size or density, the rack 12 moves up and the baffle 9 rotates counterclockwise [as shown in the attached figure]. Figure 1 As shown, at this time, the settled dust will be guided by the baffle 9 and enter the second dust collecting chamber 6 for collection. When the particle size or density of the settled dust is small, the rack 12 moves down and the baffle 9 rotates clockwise. At this time, the settled dust will be guided by the baffle 9 and enter the first dust collecting chamber 5 for collection. The staff can switch and adjust the dust settling space according to the use requirements, open the ash discharge valve 7, and discharge the dust in the first dust collecting chamber 5 or the second dust collecting chamber 6 through the ash discharge valve 7. Turn on the vibration motor 13, and the vibration generated by the vibration motor 13 can shake off the dust hanging on the wall to avoid blockage and non-discharge. The gravity dust collector for cast iron pipe production involved in the present invention effectively solves the problem that the existing similar equipment cannot collect dust in different zones according to different particle sizes or densities through innovative design, thereby bringing many significant beneficial effects; In terms of subsequent treatment, targeted treatment can be achieved according to the different characteristics of dust, greatly improving the efficiency of subsequent treatment. Dust of different particle sizes and densities can be collected separately, so that the most suitable treatment method can be adopted for each part of dust, avoiding the inefficiency caused by a unified treatment method, and ensuring the smoothness and efficiency of the entire dust treatment process; For resource recycling, the present invention enables the valuable components in dust to be screened and extracted more conveniently. Through zoning collection, the valuable components contained in dust with different characteristics can be clearly distinguished, making it easier to process dust containing valuable components such as recyclable metal particles separately, effectively improving resource recovery rate, reducing production costs, and effectively promoting energy conservation and emission reduction as well as full utilization of resources; It also has obvious advantages in the operation and maintenance of the dust collector. On the one hand, it effectively reduces the risk of clogging of the ash hopper. The collection of dust of different particle sizes can avoid the blockage of the ash outlet caused by fine dust filling the gaps between large particles, ensuring the normal ash discharge function of the ash hopper, maintaining the overall stable operation of the dust collector, reducing the frequent shutdown and cleaning due to blockage, and significantly improving production efficiency. On the other hand, it extends the service life of the equipment. According to the difference in wear of the ash hopper and dust collector by dust of different characteristics, corresponding protective measures can be taken to reduce the damage of dust to the equipment, thereby reducing the cost of equipment renewal and maintenance; In addition, it is more convenient in terms of monitoring and management. It can accurately monitor the accumulation amount and accumulation speed of dust in different partitions, and provide accurate data support for the operation adjustment of the dust collector, such as accurately determining the cleaning time and dust discharge frequency. At the same time, the staff can formulate more targeted management measures based on the different characteristics of dust, such as strengthening anti-theft and anti-leakage measures for the partitions collecting valuable dust, and strengthening the sealing and ventilation management of the fine-grained dust partitions that are prone to dust generation, etc., which comprehensively improves the management level and safety of the entire dust collector system; In summary, the present invention brings substantial improvements and significant efficiency enhancements to dust removal and related work in the production process of cast iron pipe fittings in multiple key aspects.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
