A pulse dust removal filter bag detection and replacement device and operation method

Abstract

The present invention discloses a pulse dust removal filter bag detection and replacement device, which includes a circulating track seat. A slotted section and a closed section are provided on the side of the circulating track seat. It uses the circulating track seat combined with a circulating conveyor line to drive the module of the dust removal filter bag to move in a circular motion in the annular groove. Among them, the gas to be filtered enters the cavity of the annular groove seat through the slot of the annular groove and is led out through the air outlet pipe. During the circular motion, the filtering operation can be continuously carried out. The annular groove is also provided with a slotted end and a closed section. The gas filtering operation is carried out at the slotted end. While at the closed section, the air outlet pipe of the connecting part of the dust removal filter bag is closed, so this part of the dust removal filter bag does not work, and the filtering chamber is not connected to the air outlet pipe. Therefore, at this working position, it is convenient to carry out operations such as pulse cleaning, disassembly, repair and replacement of the dust removal filter bag alone, without affecting the filtering of other working positions.

Description

Technical Field

[0001] The present invention relates to the field of dust removal for underground operations, and particularly relates to a pulse dust removal filter bag detection and replacement device and an operation method thereof. Background Technique

[0002] Mine dust is the general term for fine particles of solid substances generated during the mine production process. It is abbreviated as mine dust. Coal mines emit a large amount of dust into the air during various links such as production, storage, transportation, and roadway tunneling.

[0003] At present, traditional industrial pulse dust removal equipment uses the reverse blowing dust removal method, which can also be called reverse blowing air flow. This method often adopts a working system of separate rooms, and then automatically adjusts the air flow direction of each separate room to the opposite direction through valves. In order to act more on the internal filter screen, the huge vibration generated can make the dust fall off. Along with the pulse valve sending the high-pressure reverse air flow used for dust cleaning into the bag, the filter bag bulges rapidly, and the filtering effect of the filter bag is not good. Even during the process of the high-pressure air flow rushing into the filter bag, the filter bag may be damaged. At present, the replacement of the filter bag needs to be carried out under shutdown conditions, the operation is relatively complicated, and it is not possible to know well which group of filter bags is damaged. At the same time, it also needs to be shut down for replacement, which affects the dust treatment and brings certain hidden dangers to coal mine mining. Summary of the Invention

[0012] An operating method using the above-mentioned pulse dust removal filter bag detection and replacement device, characterized by: including a pulse dust removal mode, a bag leakage detection mode and a filter bag replacement mode;

[0013] Pulse dust removal mode: The equipment is running normally. During this process, the air quality detection module continuously detects and sets the pulse dust removal interval time T1. After the interval time T1 is reached, the circular conveyor line runs one station, and the corresponding connection part runs to the position of the inflation nozzle module.

Detailed implementation manners

[0028] The present invention will be further described in detail below in conjunction with the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention and the present invention is not limited to the following embodiments.

[0029] See Figures 1-9, in this embodiment, a pulse dust removal filter bag detection and replacement device includes a circulating track base 101. A slotted section 102 and a closed section 103 are provided on the side of the circulating track base 101. The slotted section 102 communicates with the cavity inside the circulating track base 101. The slotted section 102 and the closed section 103 are arranged in an annular groove 105 on the side of the circulating track base 101. A belt 104 is attached to the annular groove 105. The air outlet pipe 106 of the connecting part of the dust removal filter bag is connected to the belt 104 so that its inner side fits on the annular groove 105. The air outlet pipe 106 fits in the slotted end and communicates with the cavity inside the circulating track base 101. The air outlet pipe 106 fits and adheres to the closed section 103 so that the air outlet pipe 106 is closed. A circulating conveyor line 107 is provided on the circulating track base. The connecting parts are fixedly connected to the conveyor belt of the circulating conveyor line 107 at equal intervals. The connecting parts and the belt 104 are driven by the conveyor belt to circulate around the annular groove 105. The box body 147 of the adapted pulse dust removal equipment is provided with an air inlet module connected to the filter chamber of the box body 147. The circulating track base 101 is provided with an air outlet pipe 150. The air outlet pipe 150 communicates with the cavity of the annular groove 105 seat and extends outside the box body 147. In this embodiment, it uses the circulating track base 101 combined with the circulating conveyor line 107 to drive the module of the dust removal filter bag to circulate in the annular groove 105. The gas to be filtered enters the cavity of the annular groove 105 seat from the slot of the annular groove 105 and is led out by the air outlet pipe 150. During the circulating movement, the filtering operation can be continuously carried out. The annular groove 105 is also provided with a slotted end and a closed section 103. The gas filtering operation is carried out at the slotted end. While at the closed section 103, the air outlet pipe 150 of the connecting part of the dust removal filter bag is closed, and this part of the dust removal filter bag does not work. The filter chamber is not connected to the air outlet pipe 150. Therefore, at this working position, it is convenient to carry out operations such as pulse cleaning, disassembly and replacement of the dust removal filter bag alone, without affecting the filtering of other working positions.

[0030] Specifically, in this embodiment, a pulse inflation module is provided at one end of the circular track seat. An inflation nozzle 116 module is provided at the connecting portion. The inflation nozzle 116 module includes a main pipe body 108, a valve seat 109, a valve core 110, and a pushing member 111. The main pipe body 108 is provided with a pipe orifice channel 112 for connecting the internal cavity of the circular track seat 101. The pipe orifice channel 112 is connected to the air outlet pipe orifice 106. The valve seat 109 is fixed to the cavity of the main pipe body 108. The valve seat 109 is provided with a number of first air inlet channels 113. The valve core 110 is provided with a second air inlet channel 114. The first air inlet channels 113 and the second air inlet channels 114 are arranged in an alternating manner. The pushing member 111 is provided with a push rod slidably passing through the valve seat 109 and connected to the valve core 110 through an elastic member 149. Under the action of the elastic member 149, the valve seat 109 and the valve core 110 are in contact and arranged at the initial position. A contact port adapted to the valve core 110 is provided below the main pipe body 108. When the valve core 110 is adapted to the contact port, the valve core 110 closes the pipe orifice channel 112. The pulse inflation module includes an air storage tank 115, an inflation nozzle 116 adapted to be connected to the upper end of the main pipe body 108, and a lifting module 117. The lifting module 117 and the air storage tank 115 are fixed on the annular groove 105 seat. The inflation nozzle 116 is arranged to slide up and down by connecting the lifting module 117. When the inflation nozzle 116 descends and is in contact and adapted to the pushing member 111 for pulse mode inflation and dust cleaning. In this structure, during the normal filtering process, due to the action of the elastic member 149, the valve seat 109 and the valve core 110 are in contact and closed. At this time, the lower end of the main pipe body 108 is in communication with the pipe orifice channel 112 for normal filter bag filtering. When pulse jet dust cleaning is required, the inflation nozzle 116 presses down the pushing member 111, then the valve seat 109 and the valve core 110 are separated, and the first air inlet channels 113 and the second air inlet channels 114 are in communication. Compared with the traditional structure, there is no need to set multiple valve bodies. At the same time, in this structure, since the front end of the pipe orifice channel 112 is closed by the valve core 110, when high-pressure gas is conducted, the gas will not be conducted into the front pipe body of the pipe orifice channel 112, making the introduction of high-pressure gas more uniform and not easily causing problems such as uneven air flow introduction due to irregular cavity and air flow disturbance. Specifically, the elastic member 149 adopts a spring member. The spring member is arranged in the installation groove of the valve seat 109. One end of the spring member is fixed to the valve core 110, and the other end of the spring member is fixed to the bottom of the installation groove. The second air inlet channel 114 has a central opening in the valve core 110. The first air inlet channels 113 have openings on the eccentric side of the valve seat 109, and the openings of a number of first air inlet channels 113 are concentrically arranged and have the same size and specification. The central opening causes the air flow to be introduced from the center, further making the gas introduction uniform.

[0031] In this embodiment, a side chamber is further provided in the box body 147 relative to the filtering chamber. The side chamber and the filtering chamber are isolated by a slidable side door 118 that can be opened. A manipulator is provided in the side chamber. The manipulator is arranged at the other end of the circulating track base 101. The manipulator is used to remove the filtering part installed on the sliding seat 121 and move it to the side chamber. A first inspection door 145 communicating with the side chamber is provided on the box body 147. The manipulator includes an axial conveying part 119 and a double-claw mechanical gripper 120. The axial conveying part 119 is connected to the picking claw. The connecting part includes a sliding seat 121 and a fixed base 122. The inflating nozzle 116 module and the air outlet pipe orifice 106 are arranged on the sliding seat 121. Fixed components are provided on both sides of the fixed base 122. The fixed components include a clamping block 123 and a fixed buckle 124. The clamping block 123 is fixed to the fixed buckle 124. The sliding seat 121 is provided with a slot, and a sliding rod 125 is arranged in the slot. The fixed buckle 124 is slidably arranged on the sliding rod 125. A return spring 126 is sleeved on the sliding rod 125 and contacts or is fixed to the fixed buckles 124 on both sides respectively. The fixed buckle 124 is provided with a limiting block 127. The sliding seat 121 is provided with a guide slot and a limiting slot 128 adapted to the fixed buckle 124. In this structure, without stopping the work, the module of the filter bag 148 to be replaced is conveyed to the other end of the circulating conveying part. The side sliding door 118 is opened, and the module composed of the filter bag 148 is removed by the manipulator and placed into the side chamber. After the internal static state is stable, the filter bag 148 is repaired and maintained. During this process, the normal filtering work of the equipment is not affected. Specifically, the manipulator includes an axial conveying part 119 and a double-claw mechanical gripper 120. The axial conveying part 119 is connected to the picking claw. Fixed components are provided on both sides of the fixed base 122. The fixed components include a clamping block 123 and a fixed buckle 124. The clamping block 123 is fixed to the fixed buckle 124. The sliding seat 121 is provided with a slot, and a sliding rod 125 is arranged in the slot. The fixed buckle 124 is slidably arranged on the sliding rod 125. A return spring 126 is sleeved on the sliding rod 125 and contacts or is fixed to the fixed buckles 124 on both sides respectively. The fixed buckle 124 is provided with a limiting block 127. The sliding seat 121 is provided with a guide slot and a limiting slot 128 adapted to the fixed buckle 124. During the installation process, the manipulator clamps the clamping block 123, so that the fixed buckle 124 contracts inward, and its position is adapted to the guide slot. Then it is inserted into the guide slot, and the fixed buckle 124 is gradually released. The limiting block 127 is adapted to the limiting slot 128, so that the sliding seat 121 is fixed to the fixed base 122. On the contrary, the module composed of the filter bag 148 can be removed.

[0032] In the above operation, the filter bag 148 is set to move in a cycle. Pulse cleaning is carried out at one end, and a set of pulse devices is used, which is convenient to control, relatively easy to control, ensures the stability of the pulse gas, and also relatively controls the cost. A replacement component is set at the other end, which facilitates the replacement of the filter bag 148 module without stopping the machine. Thus, in most cases, the dust removal work in the mine can be carried out normally. At the same time, the filter bag 148 module moves in a cycle on the circular track seat 101, which is convenient to contact with various positions in the filter chamber, so as to ensure the relative consistency of the basic dust environment of the filter bags at each working station. Therefore, effectively setting the consistent pulse parameters of the pulse gas has a good effect on the cleaning of the filter bag 148, avoiding incomplete cleaning or increased damage to the filter bag during the dust removal process due to too large or too small pulse gas settings, and reducing the service life of the filter bag 148.

[0033] In this embodiment, a filter bag installation module is provided in the connecting portion. The filter bag installation module includes a Venturi tube 129, a conical guide block 130, a first guide plate 131, and a second guide plate 132. A conical guide block 130 is arranged in the lower end cavity of the Venturi tube 129. A number of first guide holes are arranged at equal intervals and at equal angles concentrically along the edge of the gap between the Venturi tube 129 and the conical guide block 130. The first guide holes are arranged on the first guide plate 131. The first guide holes are connected to corresponding filter bags 148 through pipe connectors. The filter bags 148 are provided with a second guide plate 132 and are adapted with second guide holes. The conical guide block 130 is provided with a driving motor 133. The motor shaft of the driving motor 133 is rotationally connected to the first guide plate 131. The first guide plate 131 is relatively fixed to the end faces of the conical guide block 130 and the Venturi tube 129. The pipe connectors include a number of straight pipes 134 and a central pipe 135. One ends of the straight pipes 134 and the central pipe 135 are sequentially connected and fixed to the first guide holes. The second guide plate 132 is relatively fixed to the Venturi tube 129. The straight pipes 134 are rotationally connected to the second guide tube. The central pipe 135 is adapted to the position of the central hole of the second guide plate 132. In this structure, as shown in the figure, the second guide holes that are not connected to the pipe connectors are fixed to the central pipe 135 through a sealing pipe 136 (solid and non-conductive). In this structure, multiple groups of filter bags 148 can be arranged on one set of connecting portions. At the same time, when the dust content in the filtered gas becomes higher, it indicates that one set of filter bags 148 may be damaged during operation. At this time, in the case of having or not having shutdown adjustment and replacement adjustment, the second guide plate 132 can be rotated sequentially for gradual screening. When the quality of the filtered gas is restored, it indicates that the filter bag 148 adapted to the position of the sealing pipe 136 is leaking and needs to be replaced. At the same time, in this structure, it can continue to be used without immediately replacing it, and be replaced when the replacement conditions are available, so as to ensure that the filter bags 148 can normally perform filtration and pulse cleaning operations.

[0034] In this embodiment, the closed section 103 is the arc section 137 of the circular orbit seat 101, the grooved section 102 is a straight section 138, the closed section 103 is arranged with an arc plate 139, and the end of the arc plate 139 has an arc extension end 140 in the direction of the grooved section 102. The air outlet 106 is provided with a first pipe fitting 141 and a second pipe fitting 142. The second pipe fitting 142 is sleeved in the socket groove of the first pipe fitting 141, and a spring member is arranged in the socket groove. The end of the second pipe fitting 142 is in surface fitting with the arc surface of the arc plate 139 (to facilitate the transition of the air outlet 106 from the straight section 138 to the arc plate 139). When there is a situation where some of the filter bags 148 in the module composed of the filter bags 148 are damaged, the above module can be gradually operated to the other end of the circular operation. When the module is at the other end, if the quality of the filtered gas resumes to be good, it indicates that the module at the end has a leak and needs to be replaced.

[0035] Preferably: The first pipe fitting 141 is provided with a sheave 143, the sheave 143 is rotatably connected to the first pipe fitting 141, the sheave 143 is adaptively arranged on the guide rail 144 of the circular groove 105, and the belt 104 is arranged in the groove adapted to the upper and lower parts of the circular groove 105, so as to ensure good running smoothness and sealing effect.

[0036] The box body 147 is further provided with a second inspection door 146 communicating with the filter chamber, which is convenient for overall maintenance inside after shutdown, and replacing the worn components inside, such as the belt 104, etc.

[0037] Based on the operation method of the above device, in this embodiment, it specifically includes a pulse dust removal mode, a leaky bag detection mode, and a filter bag replacement mode;

[0038] Pulse dust removal mode: The equipment operates normally. During this process, the air quality detection module continuously detects, sets the pulse dust removal interval time T1. After the interval time T1 arrives, the circulating conveyor line 107 runs one station, and the corresponding connecting part runs to the position of the inflation nozzle 116 module. At this time, the lifting module 117 works to press-fit the inflation nozzle 116 and the pushing member 111 and press them to the valve core 110 to close the air outlet channel. At this time, the pulse inflation module works to perform pulse inflation and dust cleaning, and circulates in turn and reciprocates;

[0039] Leakage detection mode: An air quality detection module is provided at the air outlet 106 of the air outlet pipe to detect the quality of the filtered exhaust gas. During operation, if it is found that the dust content in the detected air quality is too high, it indicates that there may be a filter bag breakage. At this time, the working time interval T2 of the circulating conveyor line 107 is set. After the circulating conveyor line 107 runs one station, the current air quality is detected at this time. If the quality is still abnormal, it continues to run one station. When the control quality is restored, there may be a leak in the filter bag module at the other end of the circulating track base 101 in the current station, and the filter bag replacement mode is triggered for replacement;

[0040] Filter bag replacement mode: The first inspection door 145 remains closed, and the side sliding door 118 is opened. At this time, the axial conveying part 119 advances forward and extends into the filtering chamber, and its double-claw mechanical gripper 120 contacts and clamps the clamping block 123. At this time, the limiting block 127 of the fixing buckle 124 of the fixed base 122 is disengaged from the limiting groove 128.
