Description

Technical Field

[0001] This utility model relates to the field of dust removal equipment technology, and in particular to a dust collection device and dust removal system. Background Technology

[0002] Pulse jet baghouse dust collectors are a common type of dust removal equipment in industry. They can not only separate solids from gases through filter bags, but also clean the filter bags by pulse backflushing them through blowpipes. They are widely used in various industrial production lines.

[0003] When the dust on the filter bags of a pulse jet baghouse dust collector accumulates to a certain amount, it will be blown off the surface of the filter bags into the collection chamber below by pulse jet cleaning. This method of dust collection requires the staff to regularly clean the dust accumulated at the bottom of the collection chamber. When cleaning the dust, the staff need to wear protective equipment, which is not only time-consuming and labor-intensive but also increases the production cost. At the same time, the dust can easily escape into the air during the cleaning process, causing environmental pollution.

[0004] Furthermore, although some existing dust collectors are equipped with ash discharge devices at the bottom, these devices can only be used when the pulse dust collector is stopped. If the dust is large, the dust outlet is prone to blockage after the dust collector has been used for a long time, causing dust backflow. Utility Model Content

[0005] Therefore, the technical problem to be solved by this utility model is to overcome the problem that in the prior art, when the dust on the filter bags of a pulse bag dust collector accumulates to a certain amount, the dust on the surface of the filter bags is blown down into the collection bin below by pulse jet cleaning. This method of collecting dust requires the configuration of corresponding personnel to regularly discharge and clean the dust accumulated at the bottom of the collection bin. During dust discharge, the personnel need to wear protective equipment, which is not only time-consuming and labor-intensive but also increases the production cost. At the same time, during the dust cleaning process, the dust is easily dispersed into the air, causing environmental pollution. Although some existing dust collectors are equipped with ash discharge devices at the bottom, these devices can only be used when the pulse dust collector is stopped. If the dust is large, the dust outlet is prone to blockage after the dust collector has been used for a long time, causing the dust to flow back.

[0006] To solve the above-mentioned technical problems, this utility model provides a dust collection device for discharging and cleaning dust filtered out by a pulse bag filter, including:

[0007] support;

[0008] A weighing sensor is disposed at the bottom of the bracket;

[0009] A collection chamber is disposed on the top of the bracket. The collection chamber includes an internal cavity, at least one connection port is provided on the side of the collection chamber, and an output port is provided at the bottom of the collection chamber.

[0010] The dust collection pipe is provided at least one, one end of which is connected to a dust discharge port of the pulse bag dust collector, and the other end is connected to the connection port.

[0011] A diaphragm pump is disposed on one side of the support, the inlet of the diaphragm pump is connected to the outlet, and the outlet of the diaphragm pump is connected to a discharge pipe.

[0012] In one embodiment of the present invention, the support includes a main body, which is a frame structure. At least three legs are vertically connected to one end face of the main body, and a weighing sensor is connected to the end of each leg away from the main body.

[0013] In one embodiment of this utility model, the collection chamber is coaxially connected to the main body, and the collection chamber is provided with a switch door.

[0014] In one embodiment of this utility model, the feed port of the diaphragm pump is connected to the output port through a flexible pipe.

[0015] In one embodiment of this utility model, a controller is also included, which is connected to the diaphragm pump and the weighing sensor respectively.

[0016] In one embodiment of this utility model, the bottom of the collection chamber is conical.

[0017] In one embodiment of this utility model, a check valve is provided on each of the dust collection pipes.

[0018] In one embodiment of this utility model, the dust collection pipe is a PU steel wire corrugated pipe.

[0019] In one embodiment of this utility model, a valve is provided on the discharge pipe.

[0020] A dust removal system includes a dust collection device as described in any of the above claims.

[0021] The above-mentioned technical solution of this utility model has the following advantages compared with the prior art:

[0022] The dust collection device and dust removal system described in this utility model can introduce the dust discharged from the pulse bag dust collector into the collection chamber for centralized discharge. No machine shutdown is required during the dust discharge process, reducing downtime of the dust removal equipment and effectively improving its dust removal efficiency. Furthermore, the dust dispersion can be effectively controlled during the dust discharge process, protecting the surrounding environment from pollution. Simultaneously, the weight of the dust in the collection chamber is monitored in real time by a weight sensor or the number of pulse backflushing cycles, enabling the determination of the amount of dust collected and thus achieving timely dust removal, ensuring the stable operation of the unit.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0028] Example 1: Refer to Figure 1 and Figure 2 As shown, this utility model discloses a dust collection device for discharging and cleaning dust filtered out by a pulse bag filter A, comprising:

[0029] Bracket 1;

[0030] Weighing sensor 2 is located at the bottom of bracket 1;

[0031] Collection chamber 3 is located on the top of support 1. Collection chamber 3 includes an internal cavity. At least one connection port is provided on the side of collection chamber 3, and an output port is provided at the bottom of collection chamber 3.

[0032] Dust collection pipe 4, at least one dust collection pipe 4 is provided, one end of the dust collection pipe 4 is connected to a dust discharge port of the pulse bag dust collector, and the other end is connected to a connection port;

[0033] A diaphragm pump 5 is installed on one side of the support 1. The inlet of the diaphragm pump 5 is connected to the outlet, and the outlet of the diaphragm pump 5 is connected to the discharge pipe 51.

[0034] Specifically, the support frame 1 is located below the pulse bag filter. A weighing sensor 2 is installed at the bottom of the support frame 1, and a collection chamber 3 is installed at the top of the support frame 1. The cavity inside the collection chamber 3 is connected to each dust discharge port of the pulse bag filter through at least one dust collection pipe 4. The bottom of the collection chamber 3 is connected to the inlet of the diaphragm pump 5 located on one side of the support frame 1 through a flexible pipe 6. At the same time, a discharge pipe 51 is installed at the outlet of the diaphragm pump 5. The output end of the discharge pipe 51 is connected to a packing bag or directly connected to a treatment pool for placing and treating dust.

[0035] During the production process, the weight of the collection bin 3 is detected in real time by the weighing sensor 2. When the weight of the collection bin 3 reaches the highest threshold, the PLC controller controls the diaphragm pump 5 to start. The diaphragm pump 5 can pump out the dust in the collection bin 3 to achieve centralized emission and collection of dust. The diaphragm pump 5 is turned off when the weighing sensor 2 detects that the weight of the collection bin 3 has dropped to the lowest threshold.

[0036] This utility model discloses a dust collection device that can collect dust generated after pulse jet cleaning of a pulse bag filter. Once the dust reaches a certain level, it is automatically discharged to a predetermined location for further collection and treatment. This not only reduces manual labor intensity but also improves dust handling efficiency and reduces the possibility of dust escaping and polluting the surrounding environment. The entire device has a simple structure, is easy to install and maintain, and is highly practical.

[0037] Furthermore, the support 1 includes a main body 11, which is a frame structure. At least three legs 12 are vertically connected to one end face of the main body 11, and a weighing sensor 2 is connected to the end of each leg 12 away from the main body 11.

[0038] Furthermore, the collection chamber 3 is coaxially connected to the main body 11, and a switch door 31 is provided on the collection chamber 3. Specifically, the switch door 31 allows for periodic cleaning and maintenance of the collection chamber 3, ensuring the stable operation of the dust collection device. It is important to ensure that the switch door 31 has sufficient sealing when closed to prevent dust from escaping from the gaps in the switch door 31.

[0039] Furthermore, the inlet of the diaphragm pump 5 is connected to the outlet via a flexible pipe 6.

[0040] Furthermore, it also includes a controller, which is connected to the diaphragm pump 5 and the load cell 2. The controller can be a PLC controller.

[0041] Furthermore, the bottom of the collection chamber 3 is conical. Specifically, the conical bottom structure of the collection chamber 3 allows the dust entering the collection chamber 3 from the dust discharge port of the pulse bag filter to be guided and collected to the center of the bottom of the collection chamber 3, which is beneficial for the dust to be discharged from the outlet at the bottom of the collection chamber 3.

[0042] Furthermore, each dust collection pipe 4 is equipped with a check valve 41, which can prevent the dust-laden air in the collection chamber 3 from flowing back.

[0043] Furthermore, the dust collection pipe 4 is made of PU steel wire corrugated pipe. It can be imagined that the flexible connection between the dust collection pipe 4 and the dust discharge port of the pulse bag dust collector can play a buffering role in the dust discharge process, which can not only prevent dust from overflowing, but also avoid affecting the weighing sensor 2, thus ensuring the accuracy of weighing.

[0044] Furthermore, a valve is installed on the discharge pipe.

[0045] Example 2: Based on Example 1, another method is provided to detect the amount of dust in the collection chamber 3. Specifically, the PLC controller is electrically connected to the electromagnetic pulse valve of the pulse bag dust collector. The amount of dust in the collection chamber 3 is determined by detecting the number of pulse backflushes of the electromagnetic pulse valve. After a certain number of backflushes, the controller sends a control signal to start the diaphragm pump 5 to centrally discharge the dust.

[0046] Example 3: This utility model also discloses a dust removal system, including the dust collection device as in Example 1.

[0047] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
