Description

Technical Field

[0001] This utility model relates to a dust collection device, specifically a dust collection device for the dust outlet of a dust collector. Background Technology

[0002] To meet environmental protection requirements, many enterprises, such as power plants, use dust collectors in their production equipment. After a certain amount of dust is collected, it is discharged through the ash outlet and then transported out via a trolley. To avoid dust re-entrainment during ash discharge, a dedicated ash-collecting device is required at the ash outlet. This device is generally used in conjunction with a ash-collecting trolley. However, this trolley is quite bulky and requires a special lifting device to raise it and connect it to the ash outlet. This configuration increases energy consumption and equipment costs. To address this, utility model patent CN28370625U provides a technical solution for "an ash-collecting device for an ash outlet." This solution uses a floating ash outlet and a pulley-type lifting structure to raise it. This solution has good performance, but its structure is not simple enough and its use is not very convenient, leaving room for further improvement. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a dust collector ash collection device with a simpler structure and better performance.

[0004] The technical solution of this utility model is: a dust collector ash collection device, including a floating ash collection port, a cloth covering, and an ash collection port lifting device used in conjunction with an ash collection trolley. The ash collection port lifting device includes a bracket, a lifting rod, a sling, and a hook. The bracket is vertically arranged on both sides behind the ash collection port. The bottom of the bracket is fixed to the ground. The top of the bracket is provided with a hinge. A limiting stop bar extending forward is provided near the lower part of the hinge. The lifting rod is a "gate" formed by levers on both sides and a hand-held rod in front. The structure is shaped like a "Y". The lifting rod is placed above the ash inlet, with levers on both sides of the ash inlet. The rear end of the lever is hinged to the hinge at the top of the support. The rear end of the lever rests on the limit stop. There are two sets of slings, which are set on both sides of the ash inlet. Each set of slings consists of three ropes connected to form a "Y" shape. The upper rope is fixed in the middle of one side of the lever, and the lower two ropes are fixed to the frame of the ash inlet. The hook is hung in front of the ash inlet and is used to hook the handle of the lifting rod so that the lifting rod lifts the ash inlet.

[0005] The technical advantages of this invention are: simple structure, low cost, convenient operation, and time and labor saving. It utilizes the lever principle to manually control the lifting and lowering of the suspended ash inlet, making it convenient and easy to use. Attached Figure Description

[0007] like Figure 1 and 2 As shown, a dust collector ash collection device includes a floating ash collection port 2, a covering cloth 3, and an ash collection port lifting device used in conjunction with an ash collection trolley 1. The ash collection port lifting device includes a bracket 4, a lifting rod 5, a sling 6, and a hook 7. The bracket 4 is vertically arranged on both sides behind the ash collection port 2. The bottom of the bracket 4 is fixed to the ground. The top of the bracket 4 is provided with a hinge part 8. A limiting stop bar 9 extending forward is provided below the hinge part 8. The lifting rod 5 is a "door"-shaped structure composed of levers 10 on both sides and a hand handle 11 in front. The lifting rod 5 is placed at the ash collection port. Above 2, levers 10 are positioned on both sides of the ash receiving port 2. Their rear ends are hinged to the hinged part 8 at the top of the bracket 4. After the rear ends of levers 10 fall, they rest on the limiting stop bar 9 to prevent further descent. There are two sets of slings 6, respectively located on both sides of the ash receiving port 2. Each set of slings 6 consists of three strands connected to form a "Y" shape. The upper strand is fixed to the middle position of one side lever 10, and the lower two strands are fixed to the frame of the ash receiving port 2. A hook 7 is suspended in front of the ash receiving port 2 to hook the handle 11 of the lifting rod 5, thus lifting the ash receiving port 2. Normally, the hook holds the lifting rod, keeping the ash receiving port in a high position. When receiving ash, the trolley is pushed down to the ash receiving port, and the lifting rod is lowered so that the ash receiving port falls onto the trolley's cargo box for ash receiving operations. The lifting rod tilts downwards and rests against the limiting stop bar. After collecting the ash, lift the lifting rod and attach it with the hook. The ash collection port will then rise, and the ash can be transported away by a trolley.

[0008] The bottom surface of the ash inlet 2 is provided with a sealing strip 12, which is fixed by a pressure plate 13 and screws. The sealing strip has good elasticity, and after the ash inlet falls down, its own weight presses the sealing strip firmly against the top surface of the vehicle compartment opening.

[0009] The inner edge of the sealing strip 12 is provided with a downwardly inclined overhang 14. The inclined overhang can play a certain role in automatic alignment and sealing.

[0010] The sealing strip 12 has a downwardly extending inwardly rolled edge 15 on its outer edge. This inwardly rolled edge has good deformation capability, allowing it to adhere tightly to the outer wall of the trolley after the ash collection port is placed onto the trolley's cargo box opening, resulting in a more ideal sealing effect. Even after the trolley and ash collection port have undergone some damage and deformation after a considerable period of use, they can still maintain a good sealing effect.

[0011] The length of the downward-extending eaves 14 is greater than that of the inward-curled edge 15, which facilitates automatic alignment.
