Description

Technical Field

[0001] This invention relates to the field of dust removal mixing technology, and more specifically, to a dust collector and a small material weighing system. Background Technology

[0002] The small material weighing system generates dust during the unpacking and weighing processes. This dust settles on the equipment, affecting its performance and creating a dust cloud in the workspace, posing a flammable and explosive safety hazard. Therefore, the system needs to be equipped with a dust collector to collect the dust generated during unpacking and weighing.

[0003] Currently, the common configuration for dust collectors is centralized dust collection, which uses one (or two) dust collectors to collect dust generated during the unpacking and weighing processes at each workstation. The dust from each workstation is collected in the dust collector's hopper, resulting in mixed materials that cannot be recycled and generate waste. Furthermore, as hazardous chemicals, this waste requires disposal by a qualified third party. The existing dust collection solution not only wastes raw materials and causes environmental pollution but also increases the company's operating costs.

[0022] Compared to the background technology description, the aforementioned dust collector is used for dust removal at a single station of a small material weighing system. It includes a chassis containing independently arranged unpacking dust removal chambers and weighing dust removal chambers. The unpacking dust removal chamber is connected to the unpacking chamber and has a first dust removal component and a first cleaning component. The first dust removal component collects dust from the unpacking chamber.

[0036] The core of this invention is to provide a dust collector and a small material weighing system to solve the problems of raw material waste, environmental pollution and high operating costs that exist when the small material weighing system collects dust generated during the unpacking and weighing process.

[0037] 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.

[0039] This invention specifically provides a dust collector for dust removal at a single station of a small material weighing system. It includes a housing 1, within which are independently arranged unpacking dust removal chamber 11 and weighing dust removal chamber 12. The unpacking dust removal chamber 11 communicates with the unpacking chamber and has a first dust removal component 2 and a first dust removal component 3. The first dust removal component 2 collects dust from the unpacking chamber; the first dust removal component 3 blows away the dust collected in the unpacking dust removal chamber 11, causing the dust to fall back into the hopper of the unpacking chamber. The weighing dust removal chamber 12 communicates with the hoppers of the weighing chamber and the unpacking chamber and has a second dust removal component 4, a valve plate 6, and a second dust removal component 5. The second dust removal component 4 collects dust from the weighing chamber; the valve plate 6 is located between the weighing dust removal chamber 12 and the hopper of the unpacking chamber to control their opening and closing; the second dust removal component 5...

[0040] The dust component 5 is used to blow the dust collected in the weighing and dust removal chamber 12 onto the valve plate 6, so that when the valve plate 6 is opened, the dust falls back into the hopper of the unpacking chamber.

[0041] In practical applications, this dust collector is installed at a single station of a small material weighing system. When the unpacking chamber is performing an unpacking operation, the unpacking dust collection chamber at the current station starts working, collecting dust from the unpacking chamber through the first dust collection component. After unpacking is completed, the unpacking door of the unpacking chamber is closed, and the dust in the unpacking dust collection chamber is blown off by the first dust removal component. The blown-off dust falls back into the material hopper of the unpacking chamber, realizing the recycling and reuse of dust materials during the unpacking process. When the weighing chamber is performing a weighing operation, the weighing dust collection chamber at the current station starts working, collecting dust from the weighing chamber through the second dust collection component. When the weighing chamber is about to perform a weighing operation, the dust in the weighing dust collection chamber is blown off onto the valve plate by the second dust removal component. After the weighing chamber completes the required weighing cycle operation, the valve plate is opened, and the collected dust falls into the material hopper of the unpacking chamber, realizing the recycling and reuse of dust materials during the weighing process. By installing the aforementioned dust collectors at each station of the small material weighing system, the dust generated during unpacking and weighing processes will not mix with other materials, and the dusty raw materials can be recycled and reused, effectively avoiding problems such as raw material waste, environmental pollution, and high operating costs. In addition, the unpacking dust removal chamber and the weighing dust removal chamber of the dust collector are two independent chambers that do not affect each other during operation, which can effectively ensure dust removal efficiency and weighing efficiency.

[0042] It should be noted that the unpacking and dust removal chamber 11 can be directly connected to the unpacking chamber, for example, it can be directly fixed above the unpacking chamber, or it can be connected through an unpacking pipeline; the weighing and dust removal chamber 12 is preferably connected by a weighing and dust removal pipeline, but it can also be directly fixed above the weighing chamber, but it is necessary to ensure that the dust raw materials collected by the weighing and dust removal chamber 12 fall onto the valve plate 6.

[0043] In some specific implementations, the first dust removal component 2 may specifically include a first dust removal fan 21 and a first dust collection device 22. The first dust removal fan 21 is used to draw dust from the unpacking chamber into the unpacking dust removal chamber 11; the first dust collection device 22 is installed in the unpacking dust removal chamber 11 and is used to collect dust.

[0044] Dust. In the specific working process, the suction force of the first dust removal fan 21 provides negative pressure to the unpacking and dust removal chamber 11, thereby sucking in the dust in the unpacking chamber. The first dust collection device 22 can be made of filter material, as long as it can meet the requirements of collecting dust, without further specific limitations.

[0045] In a further embodiment, the unpacking and dust removal chamber 11 may specifically include a first buffer chamber 111 and a first collection chamber 112 arranged sequentially from bottom to top; wherein, the first buffer chamber 111 is connected to the unpacking chamber; the first dust removal fan 21 is disposed outside the unpacking and dust removal chamber 11, and the suction end of the first dust removal fan 21 is connected to the first buffer chamber 111, the discharge end of the first dust removal fan 21 is connected to the first collection chamber 112, and the first dust collection device 22 is installed in the first buffer chamber 111 and the inlet of the first dust collection device 22 is connected to the first collection chamber 112. By designing the unpacking and dust removal chamber 11 into the above-described structure, the dust first enters the first buffer chamber 111 for buffering, and then is sucked into the first collection chamber 112, making the dust intake of the unpacking and dust removal chamber 11 more stable and avoiding blockage. In addition, the installation of the first dust collection device 22 in the first buffer chamber 111 helps to save the installation space of the first dust collection device 22, and the inlet of the first dust collection device 22 is connected to the first collection chamber 112, which enables the first dust collection device 22 to collect dust stably and facilitates subsequent blowing off.

[0046] In a further embodiment, the aforementioned first dust removal component 3 may specifically include a first blowing mechanism 31 installed in the first collection chamber 112. The first blowing mechanism 31 is used to blow air into the inlet of the first dust collection device 22, so that the dust collected by the first dust collection device 22 falls back from the first buffer chamber 111 into the hopper of the unpacking chamber. By blowing air into the inlet of the first dust collection device 22 through the first blowing mechanism 31, the dust can be easily detached from the first dust collection device 22. It is understood that the first blowing mechanism 31 should generally also be connected to a first blowing power source 32, which may be an air source such as an air pump that can provide the required airflow.

[0047] In some specific implementations, the first blowing mechanism 31 preferably sprays airflow into the inlet of the first dust collection device 22 in a pulse manner. This pulsed airflow helps to further disperse the dust.

[0048] Dust falls off. It is understood that the pulsed airflow method is merely an example of an embodiment of the present invention; other blowing methods may be used in actual applications, and no further specific limitations are made here.

[0049] In some other specific embodiments, the aforementioned second dust removal component 4 may specifically include a second dust removal fan 41 and a second dust collection device 42. The second dust removal fan 41 is used to draw dust from the weighing chamber into the weighing dust removal chamber 12; the second dust collection device 42 is installed in the weighing dust removal chamber 12 and is used to collect dust. In specific operation, the suction force of the second dust removal fan 41 provides negative pressure to the weighing dust removal chamber 12, thereby drawing dust from the weighing chamber. The second dust collection device 42 may be made of filter material, as long as it can meet the requirements for collecting dust, without further specific limitations.

[0050] In a further embodiment, the weighing dust removal chamber 12 may specifically include a second buffer chamber 121 and a second collection chamber 122 arranged sequentially from bottom to top. The second buffer chamber 121 is connected to the weighing chamber and is openably and closeably connected to the hopper of the unpacking chamber through a valve plate 6. The second dust removal fan 41 is located outside the weighing dust removal chamber 12, and the suction end of the second dust removal fan 41 is connected to the second buffer chamber 121, the discharge end of the second dust removal fan 41 is connected to the second collection chamber 122, and the second dust collection device 42 is installed in the second buffer chamber 121 and the inlet of the second dust collection device 42 is connected to the second collection chamber 122. By designing the weighing dust removal chamber 12 into the above-described structure, the dust first enters the second buffer chamber 121 for buffering, and then is sucked into the second collection chamber 122, making the dust intake of the weighing dust removal chamber 12 more stable and avoiding blockage. In addition, the installation of the second dust collection device 42 in the second buffer chamber 121 helps to save the installation space of the second dust collection device 42, and the inlet of the second dust collection device 42 is connected to the second collection chamber 122, which enables the second dust collection device 42 to collect dust stably and facilitates subsequent blowing off.

[0051] In a further embodiment, the aforementioned second dust removal component 5 may specifically include a second blowing mechanism 51 installed within the weighing dust removal chamber 12. The second blowing mechanism 51 is used to blow air into the inlet of the second dust collection device 42, so that the dust collected by the second dust collection device 42 falls back from the second buffer chamber 121 into the hopper of the unpacking chamber when the valve plate 6 is opened. By blowing air into the inlet of the second dust collection device 42 through the second blowing mechanism 51, the dust can be easily detached from the second dust collection device 42. It is understood that the second blowing mechanism 51 should generally also be connected to a second blowing power source 52, specifically an air source such as an air pump that can provide the required airflow.

[0052] In some more specific embodiments, the second blowing mechanism 51 preferably blows airflow into the inlet of the second dust collection device 42 in a pulse manner. This pulsed blowing of airflow is more conducive to dust removal. It is understood that the use of a pulsed blowing method is merely an example of an embodiment of the present invention; other blowing methods may be used in actual applications, and no further specific limitations are made here.

[0053] In some more specific implementations, a drive assembly 7 for opening and closing the valve plate 6 can also be provided on the outer side of the weighing and dust removal chamber 12. Specifically, the valve plate 6 can be designed as a flip-up structure, and the drive assembly 7 can be a drive motor that drives the valve plate 6 to rotate around the flip axis to realize the opening and closing of the valve plate 6, or other opening and closing methods, such as the valve plate 6 can swing in the plane where the valve plate 6 is located, and the drive assembly 7 can drive the valve plate 6 to swing to realize the opening and closing, etc. In actual application, the configuration can be selected according to actual needs, and no more specific limitations are made here.

[0054] In addition, the present invention also provides a small material weighing system, including a dust collector installed corresponding to each workstation, and the dust collector is the dust collector described in any of the above-mentioned solutions. Since the dust collector has the above-mentioned technical effects, the small material weighing system with the dust collector should also have the corresponding technical effects, which will not be elaborated here.

[0055] To enable those skilled in the art to better understand the technical solutions provided by the present invention, a brief description of the specific process of the preferred technical solution of the present invention is provided below:

[0056] In practical use, the main production processes are as follows:

[0057] Unpacking and dust removal:

[0058] When the operator scans the code to unpack the package, the unpacking fan starts;

[0059] The current workstation dust collector is unpacking and cleaning the dust collection chamber to recover the dust generated during the unpacking process;

[0060] Once unpacking is complete and the unpacking door is closed, the pulse valve of the unpacking dust removal chamber is activated, and the dust is cleaned by jet cleaning. The dust blown off the filter material falls into the unpacking chamber and eventually returns to the hopper for reuse.

[0061] Weighing and dust removal:

[0062] According to the formula transmitted by the system, when the current workstation is weighing, the fan in the weighing chamber works to collect the dust generated during the weighing process through the second dust removal component (which may be a dust removal hood and dust removal pipeline).

[0063] During the rapid weighing process, the pulse valve in the weighing chamber operates to blow away dust; the dust blown off the filter material falls onto the valve plate below the dust collector.

[0064] After a certain weighing cycle is completed, the valve plate is opened, the collected dust falls into the unpacking chamber, and finally falls back into the silo for reuse.

[0065] The dust collector provided by this invention adopts a compartmentalized structure to separately recover the dust generated during the unpacking and weighing processes. The two independent chambers work independently without affecting each other, thereby improving dust removal efficiency and weighing efficiency.

[0066] Actual testing revealed that a 20-station small-material weighing system generates approximately 200 kg of waste. By adopting a compartmentalized dust collector, dust recovery reaches over 99%, saving approximately 200 kg of raw materials, resulting in material cost savings of approximately 2.4 tons per year, or about 60,000 yuan per year. It also reduces hazardous chemical handling costs by 50,000 yuan per year. Furthermore, it protects the natural environment.

For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone.
