Description

Technical Field

[0001] This utility model relates to the field of proppant production technology, and in particular to a cleaning and dust removal device for proppant production. Background Technology

[0002] Ceramsite proppant is a type of ceramic particle product with high fracturing strength. It is mainly used for downhole support in oil fields to increase the production of oil and natural gas. It is an environmentally friendly product, but its production process generates a large amount of dust, which requires a dedicated dust removal system for dust removal.

[0003] Publication No. CN223185111U discloses a dust removal system for a ceramic proppant production workshop. By starting a water pump, water from a water tank is introduced into a ring pipe through an outlet pipe, and then sprayed in a ring through nozzles on the ring pipe. This allows the gas carrying dust to be better sprayed with water as it passes through the exhaust pipe, thereby further removing dust from the airflow. The sprayed water is collected in a conical pipe through a drainage channel and flows back to the water tank through the inlet pipe, enabling the device to continuously treat dust and improving its dust handling capacity.

[0004] However, during the implementation of this scheme, dust is reduced by spraying the exhaust gas in a ring. Since the exhaust fan absorbs and discharges the dust, the exhaust airflow has a certain impact force. As the airflow passes through the spray channel, it is easy to blow water and water that has absorbed dust directly out of the device, thus polluting the environment around the equipment and resulting in poor performance. Therefore, a dust removal and cleaning device for proppant production is proposed. Utility Model Content

[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a cleaning and dust removal device for proppant production, including a collection box 1 installed on one side of a weighing conveyor belt. The inner bottom wall of the collection box 1 is conical and filled with clean water for dust treatment. A dust suction hood is provided on one side of the collection box 1 to absorb dust mixed in the ceramsite proppant. The structure of the dust suction hood is the same as that in the prior art and has been specifically disclosed. Since this is not the focus of this application, it will not be discussed in detail here. The inside of the collection box 1 is rotatably connected to a box door 2. The surface of the box door 2 is inlaid with a viewing window 3. The viewing window 3 facilitates the staff to understand the situation inside the collection box 1. At the same time, the box door 2 facilitates the subsequent washing and maintenance of the inside of the collection box 1 by the staff.

[0025] The collection box 1 is equipped with a dust removal mechanism, which includes four rotating rollers 9. The surfaces of the four rotating rollers 9 are rotatably connected to the inner wall of the collection box 1. A dust-blocking belt 10 is driven to the surfaces of the four rotating rollers 9, and the lower dust-blocking belt 10 is located in water. Water is used to clean the dust-blocking belt 10 to ensure its continuous interception effect. The dust-blocking belt 10 is preferably made of polyester needle-punched felt, which has good air permeability and strong anti-clogging properties, and can effectively intercept dust and improve the cleaning effect. A drive motor 4 is fixedly installed on the surface of the collection box 1. The output end of the drive motor 4 passes through the surface of the collection box 1 and is rotatably connected to the inside of the collection box 1. The output end of the drive motor 4 is fixedly connected to one end of a rotating roller 9 to drive the rotating roller 9, so that the dust-blocking belt 10 can rotate in the collection box 1, so that all parts of the dust-blocking belt 10 can intercept dust and ensure the cleaning and dust removal effect of the device.

[0026] The inner wall of the collection box 1 is fixedly connected to a shielding frame 11 with a conical inner wall. The shielding frame 11 is located above the dust-blocking belt 10 and is used to cover the gap between the dust-blocking belt 10 and the collection box 1, so that dust will not fall into the gap between the dust-blocking belt 10 and the collection box 1, thereby avoiding dust from being mixed in the airflow that is subsequently discharged.

[0027] Both sides of the inner wall of the collection box 1 are fixedly connected to scrapers 14 with a triangular cross section. Both scrapers 14 are in contact with the lower surface of the dust-blocking belt 10 to scrape off the dust adhering to the surface of the dust-blocking belt 10.

[0028] The collection box 1 is equipped with an air frame 12, which is located between the upper and lower layers of the dust-blocking belt 10. The top of the air frame 12 is fixedly connected with air nozzles 13 arranged at equal intervals. The air nozzles 13 are interconnected with the interior of the air frame 12, providing a channel for airflow to enter the air frame 12 and ensuring smooth airflow discharge. A suction fan 5 is fixedly installed on the surface of the collection box 1. The air inlet end of the suction fan 5 is fixedly connected to the air frame 12 and is interconnected with the interior of the air frame 12. The exhaust end of the suction fan 5 is fixedly connected to an exhaust pipe 8, which is used to guide the discharged airflow to one side to avoid affecting the operation of subsequent devices.

[0029] Fixed rods 17 are fixedly connected to both the front and rear sides of the air frame 12. The end of the fixed rod 17 away from the air frame 12 is fixedly connected to the inner wall of the collection box 1, which can create a gap between the air frame 12 and the inner wall of the collection box 1, thereby providing a space for the water droplets dripping from the air frame 12 to drain. A shielding cap 15 is mounted on the surface of the air nozzle 13. The shielding cap 15 is suspended on the air nozzle 13 by the rod, so that the shielding cap 15 does not contact the air nozzle 13. The shielding cap 15 can block the dripping water droplets, preventing the water droplets from entering the air frame 12 through the air nozzle 13 and causing the water to be drained later. The surface of the air frame 12 is provided with water channels 16 arranged at equal intervals. The inner wall of the water channel 16 is inclined. The water channel 16 is located between two adjacent sets of air nozzles 13, which collects and guides the dripping water droplets to drain, preventing the water droplets from lingering on the air frame 12 and being drained, thus ensuring the cleaning and dust reduction effect of the device.

[0030] The inside of the collection box 1 is fixedly connected to a drain pipe 6 that runs through the surface of the collection box 1. The drain pipe 6 is connected to the inside of the collection box 1. A valve 7 is installed on the drain pipe 6 to control the opening and closing of the drain pipe 6.

[0031] Working principle: When processing dust, the suction fan 5 and drive motor 4 are started simultaneously. This creates a negative pressure inside the collection box 1 through the air frame 12 and air nozzle 13, causing the airflow to carry the dust through the dust collection hood and pipes into the collection box 1. Then, driven by the airflow, some of the dust falls onto the shielding frame 11, and subsequently along the conical surface of the shielding frame 11 onto the dust-blocking belt 10, thus preventing dust from falling into the gap between the dust-blocking belt 10 and the collection box 1. Some dust falls directly onto the dust-blocking belt 10. The airflow then enters the air frame 12 through the air nozzle 13, and is then discharged from the exhaust pipe 8 by the suction fan 5. Simultaneously, the start of the drive motor 4 drives the rotating roller 9 to rotate, causing the dust-blocking belt 10 to move within the collection box. The dust-blocking belt 10 rotates within the container 1, causing the upper and lower layers of the dust-blocking belt 10 to change positions sequentially. This allows the dust-laden dust-blocking belt 10 to be submerged below the water surface in sequence. During the rotation of the dust-blocking belt 10, the scraper 14 scrapes the surface of the dust-blocking belt 10 to improve the cleaning effect of the dust-blocking belt 10 and ensure its continued dust interception effect. Meanwhile, water droplets dripping from the upper dust-blocking belt 10 are blocked by the arc surface of the shielding cap 15 and cannot enter the air nozzle 13. Guided by the arc surface of the shielding cap 15, they slide into the water trough 16 and then fall back into the water, allowing the clean airflow of the device to be discharged afterward. The dust-containing droplets are not carried out, thus improving the cleaning and dust removal effect of the device.

[0032] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
