Description

Technical Field

[0001] This utility model relates to the field of fly ash sampling technology, and in particular to a quick-release fly ash sampling device. Background Technology

[0002] Traditional coal-fired power generating units and boilers produce coal ash during the combustion process when burning coal to generate heat. In order to determine the combustion quality in the boiler, it is usually necessary to sample the fly ash inside the furnace.

[0003] Existing sampling devices require the sampling tube to be pulled out when taking samples. In order to ensure the accuracy of sampling data, staff need to take samples at the sampling point multiple times, which requires staff to disassemble and reassemble the sampling tube multiple times. The disassembly and reassembly of the existing sampling tube is cumbersome, thus affecting work efficiency. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned shortcomings by providing a quick-release fly ash collection device, thereby improving the efficiency of sampling tube assembly and disassembly, and thus increasing work efficiency.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a quick-release fly ash collection device, comprising: a sampling component, a disassembly component, and a switching unit; The sampling component includes a first sleeve, a second sleeve, and a collection assembly installed on the flue branch pipe; The second sleeve is detachably connected to the collection assembly; The disassembly and assembly component includes two lock keys that are rotatably disposed on the second sleeve. Each lock key is detachably connected to the first sleeve to lock or separate the first sleeve from the second sleeve. The on / off unit is located at the connection between the first sleeve and the flue branch pipe, and is used to control the on / off of the flue branch pipe.

[0006] Furthermore, one end of each of the key extends into the second sleeve; The first sleeve has a snap-fit ​​groove corresponding to the key insertion end.

[0007] Furthermore, the collection assembly consists of a sampling tube and a top cap disposed on and in communication with the second sleeve; The sampling tube is used to collect fly ash; The top cap is detachably disposed at the end of the sampling cylinder away from the second sleeve, and is used to open and close the sampling cylinder.

[0008] Furthermore, the sampling cylinder is equipped with a separator sleeve to guide fly ash into the sampling cylinder and prevent it from flowing back into the flue.

[0009] Furthermore, the second sleeve has through holes corresponding to each of the aforementioned key locations; Each key has a pin hole coaxial with the corresponding through hole, and a detachable pin can be inserted through each pin hole.

[0010] The beneficial effects of this utility model are reflected in: This invention controls the connection or separation of the second sleeve and the first sleeve by rotating each key, thereby adjusting the connection state between the two sleeves. After the second sleeve is separated from the first sleeve, the fly ash in the collection component can be taken out. When sampling is required again, the two sleeves are connected and each key is rotated again to constrain the first sleeve, which simplifies the operation process and improves work efficiency.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0014] Please see Figure 1-3 This utility model discloses a quick-release fly ash collection device, comprising: a sampling component 1, a disassembly component 2, and an on / off unit 3; The sampling component 1 includes a first sleeve 11, a second sleeve 12, and a collection assembly 13, which are threaded onto the flue branch pipe. The second sleeve 12 is detachably connected to the collection component 13, which is used to collect fly ash; The disassembly and assembly component 2 includes two keys 21 that are rotatably mounted on the second sleeve 12. Each key 21 is detachably connected to the first sleeve 11 and is used to control the connection or separation of the first sleeve 11 and the second sleeve 12. The on / off unit 3 is located at the connection between the first sleeve 11 and the flue branch pipe, and is used to control the on / off of the flue branch pipe.

[0015] In practice, after the staff screws the first sleeve 11 onto the flue branch pipe, they then connect the collection component 13 to the second sleeve 12, and then put the second sleeve 12 onto the first sleeve 11 and make it contact with it. At this time, the staff turns each key 21 upward so that it contacts the corresponding end of the first sleeve 11 to restrain the first sleeve 11, thereby preventing the first sleeve 11 from accidentally separating from the second sleeve 12. The staff then opens the flue branch pipe through the switching unit 3. At this time, the collection component 13 is connected to the flue. Since the flue is under positive pressure, when the fly ash mixture passes through the branch pipe, some fly ash enters the collection component 13 to complete the sampling. When samples are needed, staff close the flue branch pipe through the on / off unit 3, and then release the constraint between the disassembly component 2 and the first sleeve 11. At this time, the second sleeve 12 separates from the first sleeve 11, and staff can then remove the fly ash from the collection component 13.

[0016] This invention controls the connection or separation of the second sleeve 12 and the first sleeve by rotating each key 21, thereby adjusting the connection state between the two sleeves. After the second sleeve 12 is separated from the first sleeve 11, the fly ash in the collection component 13 can be taken out. When sampling is required again, the two sleeves are connected and each key 21 is rotated again to constrain the first sleeve, which simplifies the operation process and improves work efficiency.

[0017] Preferably, the on / off unit 3 can be a ball valve from the prior art.

[0018] In one embodiment, each key 21 is arranged in a "b" shape, and the locking end 211 of each key 21 extends into the second sleeve 12; The first sleeve 11 has a locking groove 111 on its insertion end that corresponds to the locking end 211 of the key 21. When the first sleeve 11 is fitted inside the second sleeve 12, each key 21 corresponds to the locking groove 111.

[0019] With this design, after the second sleeve 12 is fitted onto the first sleeve 11, the operator rotates each key 21 upwards, thereby changing the relative position of each key 21 and the locking groove 111, until the locking end 211 of each key 21 is engaged in the locking groove 111 and applies a clamping force close to its axis to the first sleeve 11, so as to prevent the second sleeve 12 from accidentally falling off. When the second sleeve 12 needs to be removed, the operator can turn each key 21 downwards to make the locking end 211 of each key 21 exit the slot 111.

[0020] In one embodiment, the collection assembly 13 includes a sampling cylinder 131 disposed on and in communication with the second sleeve 12, the inside of which is provided with a collection chamber for collecting fly ash. The sampling tube 131 is also equipped with a partition component to prevent fly ash from flowing back into the flue of the collection chamber; The sampling cylinder 131 is threaded with a top cap 132 at the end away from the second sleeve 12, which is used to open and close the sampling cylinder 131.

[0021] With this design, when fly ash passes through the flue branch pipe, according to the Venturi principle, some fly ash enters the collection chamber through each sleeve in sequence. At this time, the separating component prevents the fly ash in the collection chamber from flowing back into the flue. When fly ash needs to be removed, the staff can remove the constraints between each key 21 and the first sleeve, and then remove the top cap 132 to remove the fly ash from the collection chamber.

[0022] In one embodiment, the separating member includes a separating sleeve 133 vertically disposed inside the sampling cylinder 131. The inlet end of the separating sleeve 133 is connected to the second sleeve 12, and its outlet end is disposed in the middle of the collecting chamber and connected thereto, so that the bottom of the collecting chamber forms a storage chamber. The separating sleeve 133 is used to guide fly ash into the collecting chamber and prevent it from flowing back to the flue.

[0023] With this design, after the fly ash flows into the separating sleeve 133 through each sleeve, the separating sleeve 133 guides the fly ash into the collection chamber. Then, the fly ash is carried by the airflow to the top cap 132 and blocked by it. After that, it falls naturally to the bottom of the collection chamber for storage, thus avoiding fly ash backflow.

[0024] In one embodiment, the second sleeve 12 has through holes corresponding to each key 21; Each key 21 has a pin hole 212 coaxial with the corresponding through hole, and a pin 4 can be detachably inserted into each pin hole 212. When the pin 4 is inserted into the corresponding through hole and pin hole 212, it is used to constrain the rotation of the corresponding key 21.

[0025] With this design, when each key 21 rotates upward until it constrains the first sleeve 11, the pin hole 212 on each key 21 is coaxially set with the corresponding through hole. At this time, the worker inserts each pin 4 through the corresponding through hole and pin hole 212 to constrain the key 21 to rotate and improve the connection stability.

[0026] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0027] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0028] Additionally, "multiple" refers to two or more.

[0029] 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.
