Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of dust removal equipment, and in particular relates to a bag filter dust collector with a dust unloading mechanism. Background Technology
[0002] A baghouse dust collector is a dry dust filtration device. It is suitable for collecting fine, dry, non-fibrous dust. The filter bags are made of woven filter cloth or non-woven felt, utilizing the filtration effect of the fibrous fabric to filter dust-laden gas. When dust-laden gas enters the baghouse dust collector, larger, heavier dust particles settle due to gravity and fall into the ash hopper. Gas containing finer dust particles is purified as it passes through the filter media, where the dust is trapped. When a certain amount of dust accumulates in the ash hopper, it can be discharged through the ash removal system. Existing ash removal systems generally include control valves. The control valve is installed at the bottom of the lower housing (ash hopper). Opening the control valve allows ash to be discharged from the hopper. However, when there is a large amount of accumulated dust in the ash hopper or when dust adheres to the hopper, the efficiency of the control valve is low, affecting the ash removal efficiency of the ash removal system and potentially causing blockages, which is detrimental to the stable operation of the dust collection device. Utility Model Content
[0003] In view of this, the present invention aims to propose a bag filter dust collector with an ash unloading mechanism to solve the problem of low efficiency when the existing dust collectors only control the ash unloading through a control valve.
[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:
[0005] A baghouse dust collector with an ash discharge mechanism includes a dust collector and an ash hopper below it. The ash discharge mechanism is located below the ash hopper, and a support frame for supporting the dust collector is fitted on the ash hopper. The ash discharge mechanism includes an ash discharge trough, an inlet communicating with the ash hopper at the top, and an inclined section at the bottom. A first connecting pipe is located at the upward-sloping end of the ash discharge trough corresponding to the inclined section, and a second connecting pipe is located in the middle of the ash discharge trough. Both the first and second connecting pipes are connected to the ash discharge trough at one end and to a media supply device at the other end. A discharge pipe is located at the downward-sloping end of the ash discharge trough corresponding to the inclined section, with one end communicating with the ash discharge trough and a control valve at the other end.
[0006] Furthermore, the ash hopper is provided with upper and lower reinforcing components. Each reinforcing component includes several tie rods spaced apart along the length of the ash hopper. The length direction of each tie rod is perpendicular to the length direction of the ash hopper. The tie rods of the upper and lower reinforcing components are staggered.
[0007] Furthermore, the outer side of the ash hopper is provided with mesh-like reinforcing ribs.
[0008] Furthermore, the medium supply equipment includes a blower and / or a liquid supply device.
[0009] Furthermore, the support frame includes side frames and end frames. Two side frames are provided on the left and right sides of the ash hopper, and two end frames are provided on the front and rear ends of the ash hopper. The side frames and end frames are connected in sequence to form a ring-shaped support frame.
[0010] Furthermore, the end frame is provided with a triangular inner support, and the ash hopper is provided with a detachable maintenance window at the position corresponding to the opening in the middle of the inner support.
[0011] Furthermore, a toggle element is provided in the ash discharge trough at a position corresponding to the position above the first connecting pipe and the second connecting pipe. One end of the toggle element is provided with a shield that can cooperate with the first connecting pipe or the second connecting pipe, and the other end is rotatably installed on the ash discharge trough.
[0012] Furthermore, the lower part of the shield is provided with a strip groove that can cooperate with the first connecting pipe or the second connecting pipe.

[0026] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0027] A bag filter dust collector with an ash unloading mechanism, such as Figures 1 to 5 As shown, the system includes a dust collector 1 and a dust hopper 2 below it. A dust discharge mechanism is provided below the dust hopper 2, and a support frame 6 for supporting the dust collector 1 is fitted on the dust hopper 2. The dust discharge mechanism includes a dust discharge trough 3. The dust discharge trough 3 has an inlet communicating with the dust hopper 2 at the top and an inclined section at the bottom. A first connecting pipe 8 is provided at the upward end of the inclined section of the dust discharge trough 3, and a second connecting pipe 9 is provided in the middle of the dust discharge trough 3. One end of the first connecting pipe 8 and the second connecting pipe 9 are connected to the dust discharge trough 3, and the other end is connected to the medium supply device 10. A discharge pipe 4 is provided at the downward end of the inclined section of the dust discharge trough 3. One end of the discharge pipe 4 is connected to the dust discharge trough 3, and the other end is provided with a control valve (not shown in the figure).
[0028] For example, the dust collector 1 can be an existing bag filter dust collector, and the ash hopper 2 can be an existing strip-shaped ash hopper, which is installed on the dust collector 1 by conventional methods such as bolts to collect dust inside the dust collector 1. This utility model does not involve improvements to the dust collector 1, so they will not be described in detail here. In actual use, using a strip-shaped ash hopper 2 is beneficial to improving the collection capacity of the ash hopper 2.
[0029] In practical applications, the ash discharge trough 3 can also be installed on the ash hopper 2 using conventional methods such as bolts. The first connecting pipe 8, the second connecting pipe 9, and the discharge pipe 4 can also be installed on the ash discharge trough 3 using conventional methods such as bolts. The control valve can be an existing gate valve, plate valve, or other conventional valve to improve the dust passage speed and prevent blockage. The control valve and the discharge pipe 4 can be connected using conventional methods such as flanges, which will not be elaborated here. By setting the ash discharge trough 3 below the ash hopper 2 and setting an inclined surface at the bottom of the ash discharge trough 3, the dust in the ash hopper 2 can move quickly under its own gravity using the guiding effect of the inclined surface, making it less prone to blockage or accumulation. This facilitates the rapid discharge of dust through the discharge pipe 4 and the control valve, improving the ash discharge efficiency of this ash discharge mechanism.
[0030] In addition, by connecting the medium supply device 10 through the first connecting pipe 8 and the second connecting pipe 9, the operator can also use the medium supply device 10 to quickly blow gas or liquid into the ash discharge trough 3 when necessary, thereby pushing or cleaning the dust, which further improves the ash discharge efficiency of this ash discharge mechanism.
[0031] Preferably, the ash hopper 2 is provided with upper and lower reinforcing components. Each reinforcing component includes several tie rods 13 spaced apart along the length of the ash hopper 2. The length direction of each tie rod 13 is perpendicular to the length direction of the ash hopper 2, and the tie rods 13 of the upper and lower reinforcing components are staggered. For example, each reinforcing component can be provided with four, six or more tie rods 13. Both ends of each tie rod 13 can be installed and fixed to the ash hopper 2 by conventional means such as bolts. By providing upper and lower tie rods 13 and staggering the upper and lower tie rods 13, an internal support structure 12 can be formed inside the ash hopper 2, which is beneficial to improving the structural strength of the ash hopper 2, preventing deformation of the ash hopper 2 and the connection between the ash hopper 2 and the ash discharge trough 3, and improving the stability and reliability of the ash discharge mechanism during use.
[0032] In practical applications, the outer side of the ash hopper 2 is provided with mesh-like reinforcing ribs 5. For example, the reinforcing ribs 5 are fixed on the ash hopper 2. By setting the mesh-like reinforcing ribs 5, in conjunction with the reinforcing components inside the ash hopper 2, the structural strength of the ash hopper 2 can be further improved, which is beneficial to improving the ash hopper 2's ability to collect and hold dust.
[0033] Preferably, the medium supply device 10 includes a blower and / or a liquid supply device. Those skilled in the art can configure these two devices according to actual needs to accelerate the ash discharge or cleaning of the ash discharge trough 3. For example, the blower can be an existing blower, and the liquid supply device can be an existing water pump. The first connecting pipe 8 and the second connecting pipe 9 can both be connected to the blower and / or the liquid supply device respectively via external pipelines. Control valves can be installed on the external pipelines to control the on / off state of the external pipelines for different devices, allowing operators to select the appropriate medium supply device 10 according to actual needs. High-pressure medium is supplied to the ash discharge trough 3 through the first connecting pipe 8 and the second connecting pipe 9, thereby pushing or cleaning the dust in the ash discharge trough 3. Those skilled in the art can adjust or design this according to actual needs, which will not be elaborated here.
[0034] In practical applications, the first connecting pipe 8 and the ash discharge trough 3, the second connecting pipe 9 and the ash discharge trough 3, and the first connecting pipe 8 and the second connecting pipe 9 and the media supply equipment 10 can all be connected by conventional methods such as flanges and pipes to ensure the sealing performance of the connections. By setting the first connecting pipe 8 at the upward-sloping end of the ash discharge trough 3 and the second connecting pipe 9 in the middle of the ash discharge trough 3, the high-pressure medium can be supplied to the ash discharge trough 3 in cooperation with the first connecting pipe 8 and the second connecting pipe 9, which can realize the segmented pushing of dust in the ash discharge trough 3, which is conducive to improving the discharge speed of dust from the discharge pipe 4.
[0035] Preferably, the support frame 6 includes side frame bodies 7 and end frame bodies 11. Two side frame bodies 7 are provided on the left and right sides of the ash hopper 2, and two end frame bodies 11 are provided on the front and rear ends of the ash hopper 2. The side frame bodies 7 and end frame bodies 11 are connected in sequence to form a ring-shaped support frame 6. For example, the side frame bodies 7 and end frame bodies 11, the side frame bodies 7 and the ash hopper 2, and the end frame bodies 11 and the ash hopper 2 can all be connected by conventional methods such as welding. By adopting a ring-shaped support frame 6, the support frame 6 can not only provide good support for the ash hopper 2 and the dust collector 1, but also provide good protection for the ash unloading mechanism below the ash hopper 2.
[0036] Preferably, the end frame 11 is provided with a triangular inner support 12, and the ash hopper 2 is provided with a detachable maintenance window 16 at the position corresponding to the opening in the middle of the inner support 12. For example, the inner support 12 can be installed and fixed to the end frame 11 by conventional methods such as welding, and the maintenance window 16 can be installed on the ash hopper 2 by conventional methods such as bolts. By adopting the triangular structure of the inner support 12, not only is it beneficial to improve the structural strength of the end frame 11, but it can also meet the operational needs of maintenance personnel.
[0037] Preferably, a lever 15 is provided in the ash discharge trough 3 at a position corresponding to the position above the first connecting pipe 8 and the second connecting pipe 9. One end of the lever 15 is provided with a shield 14 that can cooperate with the first connecting pipe 8 or the second connecting pipe 9, and the other end is rotatably mounted on the ash discharge trough 3. Exemplarily, the shield 14 is fixed on the lever 15, and the lever 15 can be rotatably mounted on the ash discharge trough 3 by conventional means such as a rotating shaft. A rotating shaft seat that cooperates with the rotating shaft can be fixed on the inner wall of the ash discharge trough 3. Those skilled in the art can also choose other methods to install the lever 15 according to actual needs to achieve the rotatable installation of the lever 15.
[0038] In practical applications, the shield 14 is provided with a strip groove below it that can cooperate with the first connecting pipe 8 or the second connecting pipe 9. By providing a strip groove on the shield 14, the shield 14 can not only provide a good shielding and sealing effect on the ends of the first connecting pipe 8 and the second connecting pipe 9, preventing dust from clogging the first connecting pipe 8 and the second connecting pipe 9, but the strip groove also does not restrict the rotation of the actuating member 15. When the first connecting pipe 8 and the second connecting pipe 9 provide high-pressure medium into the ash discharge trough 3, they can push the shield 14 to rise and drive the actuating member 15 to rotate. By using alternating or pulsed high-pressure medium supply, the actuating member 15 can rotate repeatedly to agitate the dust, which helps to prevent dust from clogging in the ash discharge trough 3 and increases the discharge speed of dust through the discharge pipe 4.
[0039] This utility model discloses a baghouse dust collector with an ash discharge mechanism, which has the advantages of simple structure, high ash discharge efficiency, and stable reliability, thus improving dust collection efficiency. By setting an ash discharge trough below the ash hopper and an inclined surface at the bottom of the trough, the dust in the hopper can move quickly under its own gravity, preventing blockage or accumulation. This facilitates the rapid discharge of dust through the discharge pipe and control valve, improving the ash discharge efficiency of this mechanism. Furthermore, by connecting a media supply device via a first and second connecting pipe, operators can quickly inject gas or liquid into the ash discharge trough when necessary, thereby pushing or cleaning the dust and further improving the ash discharge efficiency of this mechanism.
[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
