Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of environmental protection equipment, specifically relates to a cyclone dust collector. BACKGROUND

[0002] As an important equipment in the field of industrial dust removal, cyclone dust collectors play a crucial role in industries such as cement, steel, chemical, and power. With the increasing strictness of environmental protection requirements and the continuous development of industrial technology, the application range of cyclone dust collectors is continuously expanding, and the technical level is also continuously improving. Modern cyclone dust collectors have made significant progress in separation efficiency, processing capacity, and structural optimization, and can effectively handle various dust particles to meet the dust removal needs under different working conditions.

[0003] Currently, there are various types of cyclone dust collectors on the market, including single-tube cyclone dust collectors, multi-tube cyclone dust collectors, double cyclone dust collectors, and other different types, which can adapt to various complex industrial environments and processing requirements. With the application of computational fluid dynamics technology and new structural design, some advanced cyclone dust collectors can even maintain stable dust removal performance in high-temperature, high-pressure, or corrosive environments. In addition, the separation precision of cyclone dust collectors is continuously improving, and the trapping efficiency of some high-efficiency products for fine particles has reached a high level, providing strong support for industrial clean production.

[0004] However, despite the continuous progress of cyclone dust collector technology, there are still some problems to be solved in actual application. In the long-term operation of existing cyclone dust collectors, the separated dust is prone to solidification and accumulation at the ash hopper port, causing the dust to be unable to be smoothly discharged, which seriously affects the dust removal efficiency and continuous and stable operation of the equipment. INVENTION CONTENTS

[0005] The technical problem to be solved by the utility model is to provide a cyclone dust collector that automatically cleans the ash hopper port through a cam-driven ash cleaning mechanism, effectively prevents dust solidification and blockage, and significantly improves dust removal efficiency and equipment operation reliability.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions:

[0007] A cyclone dust collector includes: a dust collector housing comprising a cylindrical upper section and a conical lower section; a tangential air inlet disposed on the cylindrical upper section; an exhaust pipe disposed at the center of the interior of the dust collector housing; a square dust hopper connected to the bottom of the conical lower section; a fan with its output shaft extending to the bottom of the square dust hopper; a bevel gear box disposed at the bottom of the square dust hopper, comprising two mating bevel gears; a rotating shaft connected to one of the bevel gears, with cams disposed at both ends of the rotating shaft; a square frame externally disposed on the cams, with a sliding connection between the square frame and the bevel gear box; a push rod disposed on the square frame; and a dust removal spring disposed on the top of the push rod. When the cams rotate, the distal end of the cams reciprocates against the upper and lower sides of the square frame, causing the square frame to reciprocate up and down, and the dust removal spring reciprocates to prevent dust from agglomerating at the dust hopper opening.

[0008] This utility model is further configured as follows:

[0009] The bevel gearbox is fixed to the bottom of the square ash hopper, and the output shaft of the blower is connected to the input end of the bevel gearbox via a coupling;

[0010] The square frame includes an upper frame plate and a lower frame plate. The square frame is slidably connected to the bevel gear box through a guide sleeve, and the guide sleeve restricts the horizontal displacement of the square frame.

[0011] The push rod is vertically mounted on the upper frame plate of the square frame, and the push rod is fixed to the square frame by a threaded connection;

[0012] The cleaning spring is a flexible steel sheet structure. The working end of the cleaning spring is arc-shaped. The cleaning spring is fixed to the top of the push rod by the clamping seat.

[0013] The transmission ratio of the two bevel gears in the bevel gearbox is 1:1, and the rotating shaft is supported in the bevel gearbox by a bearing housing;

[0014] The discharge port of the square ash hopper is located at the center of the bottom, and the reciprocating motion range of the ash cleaning spring covers the area around the discharge port;

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The cam-driven dust removal mechanism enables automatic dust removal at the ash hopper opening, effectively preventing dust from solidifying and clogging, ensuring that the separated dust can be discharged smoothly, improving dust removal efficiency, and guaranteeing the continuous and stable operation of the equipment.

[0017] Maintenance costs are significantly reduced: The automatic dust removal function eliminates the need for manual cleaning of the dust hopper opening, reduces the labor intensity and safety risks for maintenance personnel, lowers maintenance costs, and avoids wear and corrosion caused by dust agglomeration, thus extending the service life of the equipment.

[0018] Simple structure and low cost: The mechanical dust removal mechanism has a simple and reliable structure. It is directly driven by the fan power, without the need for additional power devices and complex control circuits. The equipment manufacturing cost only increases by 10-15%, and the failure rate is reduced.

[0019] Reliable operation and strong adaptability: The mechanical transmission system has low environmental requirements and can adapt to harsh working conditions such as high temperature, high humidity and corrosion. The dust removal frequency is synchronized with the fan speed, automatically adapting to different working conditions and reducing overall operating costs.

[0020] Easy installation and maintenance: The dust removal mechanism is integrated at the bottom of the dust hopper, which does not occupy additional installation space. Key components are relatively concentrated for easy inspection and maintenance. The bevel gear box is equipped with a lubrication system to ensure the long-term stable operation of the transmission system. Attached Figure Description

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] like Figure 1 , Figure 2 As shown, this utility model provides a cyclone dust collector, which mainly includes a dust collector shell 1, a dust removal mechanism and a power transmission system.

[0030] The dust collector housing 1 adopts a traditional cyclone dust collector structure, including a cylindrical upper section 2 and a conical lower section 3. The cylindrical upper section 2 is equipped with a tangential air inlet 4 for the tangential entry of dust-laden gas. The exhaust pipe 5 is located at the center of the dust collector housing 1, through which the purified gas is discharged upwards. A square ash hopper 6 is connected to the bottom of the conical lower section 3 to collect the separated dust particles. The discharge port 24 of the square ash hopper 6 is located at the center of the bottom for easy dust discharge.

[0031] like Figure 2 and Figure 3 , Figure 4 As shown, the dust removal mechanism is the core technical solution of this utility model. The output shaft 8 of the fan 7 extends to the bottom of the square ash hopper 6 and is connected to the input end of the bevel gear box 9 through a coupling 17. The bevel gear box 9 is fixed to the bottom of the square ash hopper 6 through a connecting flange 16. The box contains two mating bevel gears 10 with a transmission ratio of 1:1, realizing power transmission and direction conversion.

[0032] The rotating shaft 11 is connected to one of the bevel gears 10 and is supported in the bevel gear box 9 by a bearing seat. Cams 12 are provided at both ends of the rotating shaft 11. The cams are eccentric disc structures with an eccentricity of 5mm to 15mm.

[0033] like Figure 4 , Figure 5 As shown, the square frame 13 includes an upper frame plate 18 and a lower frame plate 19, which are externally mounted on the cam 12. The square frame 13 is slidably connected to the bevel gear box 9 through a guide sleeve 20. The guide sleeve restricts the horizontal displacement of the square frame to ensure precise up-and-down reciprocating motion.

[0034] The push rod 14 is vertically mounted on the upper frame plate 18 of the square frame 13 and is fixed to the square frame by a threaded connection. The cleaning spring 15 is fixed to the top of the push rod 14. The cleaning spring is an elastic steel sheet structure with an arc-shaped working end. Its reciprocating motion range covers part of the discharge port 24 or can be designed as a crescent shape to cover the entire surrounding area.

[0035] Working process: Dust-laden gas enters the dust collector shell 1 through the tangential inlet 4, forming a rotating airflow in the upper cylindrical section 2. Dust particles are thrown towards the wall under the action of centrifugal force and descend along the lower conical section 3 into the square ash hopper 6.

[0036] Simultaneously, when the fan 7 is running, the output shaft 8 drives the bevel gear 10 inside the bevel gear box 9 to rotate, and the rotating shaft 11 rotates accordingly, driving the cams 12 at both ends to rotate. The distal ends of the cams 12 reciprocate against the upper and lower sides of the square frame 13, causing the square frame to move up and down reciprocally, and the push rod 14 transmits the power. The dust removal spring 15 reciprocates in the area around the discharge port 24, effectively preventing dust from solidifying at the ash hopper opening.

[0037] The equipment parameters can be adjusted as follows to suit different dust characteristics and operating conditions:

[0038] Fine dust treatment: The cam eccentricity is set to 5mm, the reciprocating stroke is 10mm, the dust cleaning frequency is high, and it is suitable for the treatment of fine dust that is easy to solidify.

[0039] Coarse particle treatment: The cam eccentricity is set to 15mm, and the reciprocating stroke is 30mm, which provides strong dust removal force and is suitable for coarse dust and heavy-duty conditions.

[0040] Continuous production: The dust removal mechanism operates synchronously with the fan, requiring no additional control. The dust removal frequency automatically adapts to the fan speed, ensuring a continuous and stable production process.

[0041] The process parameter settings can ensure the dust removal effect under different working conditions, the dust removal efficiency is steadily improved by 15-25%, the equipment has good continuous operation stability, and the maintenance cost is significantly reduced.

[0042] Based on the technical effects stated in the instruction manual, the focus is on verifying the performance improvements of the cam-driven dust removal mechanism of the cyclone dust collector in terms of dust removal efficiency, maintenance costs, equipment reliability, operating costs, and ease of installation.

[0043] Verification method: A comparative experiment was conducted using standard operating conditions for dust treatment. The test conditions were a processing capacity of 1000 m³ / h and a dust concentration of 5 g / m³ for cement dust. The comparison samples consisted of three traditional cyclone dust collectors and three new cam-cleaning cyclone dust collectors, which operated continuously for 30 days.

[0044] Main test items:

[0045] Dust removal efficiency test: detection of inlet and outlet dust concentration and calculation of separation efficiency;

[0046] Maintenance cost analysis: statistics on the frequency of manual cleaning, maintenance time and cost;

[0047] Equipment reliability assessment: failure rate statistics and continuous operating time records;

[0048] Operating cost accounting: electricity consumption, spare parts replacement and overall operating expenses;

[0049] Dust removal effect monitoring: frequency of clogging at the dust hopper opening and smoothness of dust discharge.

[0053] The cam-driven dust removal mechanism achieves automatic anti-clogging function, increasing dust removal efficiency from 85% to 98%, an improvement of 15%; the reciprocating motion of the dust removal spring effectively prevents dust from solidifying at the ash hopper opening, ensuring continuous and stable operation of the equipment, and solving the key problem of efficiency decline caused by ash accumulation in traditional dust collectors.

[0054] The automatic dust removal function reduces maintenance costs by 55%, significantly reducing the frequency and intensity of manual cleaning; the simple and reliable characteristics of the mechanical transmission system reduce equipment failure rate by 37% and overall operating costs by 28%, while equipment manufacturing costs only increase by 12%, resulting in an excellent return on investment.

[0055] Mechanical dust removal mechanisms have low environmental requirements and can adapt to harsh working conditions such as high temperature, high humidity, and corrosiveness. The dust removal frequency is synchronized with the fan speed, automatically adapting to different working conditions without the need for an additional control system, greatly improving system stability and adaptability.

[0056] This invention, through a clever design of a fan-driven cam reciprocating motion, achieves an intelligent upgrade of the cyclone dust collector. It not only solves the industry problem of ash accumulation and blockage at the ash hopper opening but also provides a new technological path for the automation development of dust collection equipment. The innovative application of the cam-driven ash removal mechanism has significant technological promotion value and industrialization prospects, and is of great importance to improving the automation level of environmental protection equipment.
