Description

Technical Field

[0001] This utility model belongs to the technical field of bag dust collectors, and specifically relates to a bag picker for bag dust collectors. Background Technology

[0002] Baghouse dust collectors are a type of dry dust collection device. They are 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 down into the ash hopper due to gravity. Gas containing finer dust particles is purified by trapping the dust as it passes through the filter media. However, when the pressure difference across the filter media is large, some fine dust particles already attached to the media can be forced through, reducing the efficiency of the baghouse dust collector. Furthermore, excessively high resistance in the baghouse dust collector will significantly reduce the airflow of the dust collection system. Therefore, once the resistance of the baghouse dust collector reaches a certain value, it is necessary to clean the dust or replace the filter bags promptly.

[0003] Currently, when replacing the filter bags inside the dust collector, workers need to open the clean air chamber cover and operate from the top of the tube sheet. First, they need to pull out the cage frame, then pull out the filter bag, replace it with a new filter bag, and then put the cage frame back in. This process requires four steps to replace one filter bag. However, during the removal of the filter bag, there is a possibility that the filter bag may fall into the original air chamber. The current operation requires opening the manhole of the original air chamber to pick up the filter bag. In order to seal the manhole, there are many fixing bolts, and it is time-consuming to pick up the fallen filter bag through the manhole. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a bag picker for a bag filter, which can pick up the bags that have fallen into the dust collector's original air chamber without opening the manhole of the original air chamber.

[0005] The technical problem to be solved by this utility model is achieved by the following technical solution: a bag picker for a bag dust collector, comprising a first pull rope, a second pull rope, a connecting rope, and a first clamping rod and a second clamping rod that are hinged to each other; The first clamping rod and the second clamping rod are connected by a hinge shaft. The lower ends of the first clamping rod and the second clamping rod are respectively provided with grippers; The upper ends of the first clamping rod and the second clamping rod are respectively provided with counterweights; The lower end of the first pull rope is connected to the hinge shaft of the first clamping rod and the second clamping rod; The two ends of the connecting rope are respectively connected to the first clamping rod and the second clamping rod, and are located above the hinge axis of the first clamping rod and the second clamping rod; The lower end of the second pull rope is connected to the middle of the connecting rope.

[0006] Preferably, the first clamping rod and the second clamping rod are provided with bent handles at their upper ends; The counterweight is located at the lower end of the bending handle. This counterweight applies a downward force to the upper ends of the first and second clamping rods, enabling the grippers to open rapidly.

[0007] In a preferred embodiment of this invention, the counterweight includes an arc-shaped sliding rod, which is horizontally positioned at the lower end of the bent handle. The diameter and length of the sliding rod are both greater than the gaps in the bag filter frame. Although the filter bag is fitted on the outside of the frame, the filter bag material is relatively soft. When there are filter bags nearby, the pickup can easily wobble in the original air chamber of the dust collector and get stuck in the gaps in the frame of the adjacent frame. The pickup uses an arc-shaped sliding rod as a counterweight. Since the diameter and length of the sliding rod are both greater than the gaps in the frame of the bag filter frame, it can prevent the pickup from getting stuck in the gaps in the frame of the adjacent bag filter frame during the lowering and raising process, thus affecting the lowering and raising of the pickup.

[0008] In a preferred embodiment of this invention, the counterweight includes a spherical sliding protrusion, which is installed at the lower end of the bent handle. The diameter of the sliding protrusion is larger than the gap between the frame of the bag filter keel. Although the filter bag is fitted on the outside of the keel, the filter bag material is relatively soft. When there is a filter bag next to it, the pickup can easily shake in the original air chamber of the dust collector and get stuck in the gap between the frame of the adjacent keel. By using the spherical sliding protrusion as a counterweight, since the diameter of the sliding protrusion is larger than the gap between the frame of the bag filter keel, it is possible to prevent the pickup from getting stuck in the gap between the frame of the adjacent bag filter keel during the lowering and raising process, thus affecting the lowering and raising of the pickup.

[0009] Preferably, this invention also includes a wireless camera, which is mounted on the hinge axis of the first and second clamping rods and located below the hinge axis. The wireless camera allows for observation of the original air chamber of the bag filter, facilitating rapid positioning and retrieval of the filter bags.

[0010] Preferably, this invention also includes a lighting device connected to a wireless camera. Since the raw air chamber of the bag filter is relatively dark, the lighting device provides illumination, offering a brighter field of vision during operation and facilitating the retrieval of the filter bags.

[0011] In a preferred embodiment of this invention, the first clamping rod and the second clamping rod are respectively provided with connecting rods, and the two ends of the connecting rope are connected to the connecting rods.

[0012] Preferably, in this invention, the connecting rope is tied to the connecting rod or fitted onto the connecting rod via connecting rings. Tying the connecting rope directly to the connecting rod facilitates connection; fitting the two ends of the connecting rope onto the connecting rod via connecting rings allows the connecting rings to rotate relative to the connecting rod, thus reducing wear on the ends of the connecting rope.

[0013] In a preferred embodiment of this invention, the gripper includes a clamping plate with a width greater than that of the first clamping rod and the second clamping rod. The wider clamping plate reduces the overall weight of the bag picker in the baghouse dust collector while ensuring the gripping effect of the gripper, and increases the clamping area to avoid damage to the filter bag.

[0014] Preferably, in this invention, the first pull rope, the second pull rope, and the connecting rope are made of steel wire rope or nylon rope. Steel wire rope or nylon rope is more wear-resistant, preventing the first and second pull ropes from breaking when picking up bags dropped from the baghouse dust collector, and can also withstand greater weight.

[0015] Compared with the prior art, the beneficial effects of this utility model are: This utility model discloses a bag picker for a baghouse dust collector, comprising a first pull rope, a second pull rope, a connecting rope, and a first clamping rod and a second clamping rod hinged together. The first clamping rod and the second clamping rod are connected by a hinge shaft. Each of the first and second clamping rods has a gripper at its lower end for gripping the bag. The lower end of the first pull rope is connected to the hinge shaft of the first and second clamping rods, used for lowering and lifting the picker. Since both ends of the connecting rope are connected to the first and second clamping rods respectively, and the lower end of the second pull rope is connected to the middle of the connecting rope, the first and second clamping rods can be combined by pulling the second pull rope. The upper ends of the first and second clamping rods are respectively equipped with counterweights, used to open the first and second clamping rods after the tension of the second pull rope is removed. Based on the above structure, baghouse dust collector bags that have fallen into the raw air chamber can be picked up through the perforated plate without opening the manhole of the raw air chamber.

Detailed Implementation

[0017] The technical solutions in the embodiments of this utility model will now be clearly and completely described in conjunction with the accompanying drawings.

[0018] Example 1 like Figure 1 As shown, a bag picker for a baghouse dust collector includes a first pull rope 1, a second pull rope 2, a connecting rope 3, and a first clamping rod 4 and a second clamping rod 5 that are hinged to each other.

[0019] The first clamping rod 4 and the second clamping rod 5 are connected by a hinge shaft.

[0020] The lower ends of the first clamping rod 4 and the second clamping rod 5 are respectively provided with grippers 6. The grippers 6 are arranged opposite to each other and are located inside the first clamping rod 4 and the second clamping rod 5.

[0021] The first clamping rod 4 and the second clamping rod 5 are respectively provided with counterweights 7 at their upper ends. The counterweights 7 are located on the outside of the first clamping rod 4 and the second clamping rod 5, opposite to the position of the gripper 6, thereby giving the first clamping rod 4 and the second clamping rod 5 a force to rotate around the hinge axis.

[0022] The lower end of the first pull rope 1 is connected to the hinge shaft of the first clamping rod 4 and the second clamping rod 5.

[0023] The two ends of the connecting rope 3 are connected to the first clamping rod 4 and the second clamping rod 5 respectively, and are located above the hinge axis of the first clamping rod 4 and the second clamping rod 5.

[0024] The lower end of the second pull rope 2 is connected to the middle of the connecting rope 3.

[0025] The first clamping rod 4 and the second clamping rod 5 are provided with bent handles 8 at their upper ends.

[0026] The counterweight 7 is located at the lower end of the bent handle 8.

[0027] The counterweight 7 includes an arc-shaped sliding rod 71, which is horizontally positioned at the lower end of the bent handle 8.

[0028] The diameter and length of the sliding rod 71 are both greater than the gaps in the bag filter frame. The sliding rod 71 is welded to the bent handle 8.

[0029] The bag picker for the baghouse dust collector also includes a wireless camera 9, which is mounted on the hinge axis of the first clamping rod 4 and the second clamping rod 5, and located below the hinge axis. The wireless camera 9 is connected to a display device such as a mobile phone to observe the scene inside the raw gas chamber.

[0030] The bag filter dust collector bag pickup also includes a lighting device (not shown in the figure), which is connected to the wireless camera 9. The lighting device is an electric lamp, fixed to the front end of the wireless camera 9. Both the lighting device and the wireless camera 9 are positioned downwards.

[0031] The first clamping rod 4 and the second clamping rod 5 are respectively provided with connecting rods 10, and the two ends of the connecting rope 3 are connected to the connecting rods 10.

[0032] The connecting rope 3 is tied to the connecting rod 10 or is sleeved on the connecting rod 10 through a connecting ring.

[0033] The gripper 6 includes a gripping plate with a width greater than that of the first gripping rod 4 and the second gripping rod 5.

[0034] The first pull rope 1, the second pull rope 2, and the connecting rope 3 are made of steel wire rope or nylon rope.

[0035] Working principle: such as Figure 3 As shown, above the original air chamber of the bag filter, by applying force to the second pull rope 2, the first clamping rod 4 and the second clamping rod 5 are combined together, so that the volume of the pickup can pass through the hole of the tube sheet. Then, the combined first clamping rod 4 and the second clamping rod 5 are vertically inserted into the tube sheet hole corresponding to the dropped bag. At the same time, the first pull rope 1 and the second pull rope 2 are pulled, and under the action of gravity, the pickup is placed in the original air chamber in a vertical state.

[0036] When the first clamping rod 4 and the second clamping rod 5 are above the bag, the tension of the second pull rope 2 is released. Under the weight of the counterweight 7, the first clamping rod 4 and the second clamping rod 5 open. After the gripper 6 contacts the bag, the second pull rope 2 is pulled, causing the first clamping rod 4 and the second clamping rod 5 to rejoin, thus using the gripper 6 to clamp the bag. At the same time, the first pull rope 1 and the second pull rope 2 are pulled, causing the bag to be pulled out of the original air chamber under the grip of the gripper 6.

[0037] Example 2 like Figure 2 As shown, the difference from Embodiment 1 is that the counterweight 7 includes a spherical sliding protrusion 72, which is mounted on the lower end of the bent handle 8. The sliding protrusion 72 is welded to the bent handle 8.

[0038] The diameter of the sliding protrusion 72 is larger than the gap in the frame of the bag filter.
