Description

Technical Field

[0001] The invention relates to the technical field of dirt removal equipment, in particular to a grille dirt remover for removing dirt in urban drainage from a water collection well, and particularly to a mechanical connection structure thereof. Background Art

[0002] The drainage from large and medium-sized cities contains a large amount of ribbon-shaped and clumping solid debris. In order to avoid the blockage of the water pump during transportation, it is generally necessary to first collect and remove the solids mixed in the water from the screen decontamination machine installed in the water collection well of the pump station, and then use the water pump to transport the sewage until the sewage treatment plant undergoes further mechanical, chemical or biochemical treatment to meet the discharge standards. However, the rotary screen decontamination machine currently used in large quantities in China has many unreasonable structures, such as:

[0003] 1. The entire chain transmission mechanism is connected by two chain plates on both sides for transmission, which is prone to axial movement. Uneven force causes the chain plates to deviate during transmission, and the inconsistent stretching on both sides affects the service life.

[0004] 2. The rake teeth are connected in series on the small shaft, which makes it inconvenient to replace them when a failure occurs. Summary of the invention

[0005] The purpose of the present invention is to provide a grille dirt remover based on a hollow pin chain drive, which solves the technical problems of the existing grille dirt removers, such as large drive chain resistance, easy wear, easy deviation, and inconvenient maintenance and replacement of rake teeth, and overcomes the shortcomings and deficiencies in the prior art.

[0006] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: a grille dirt remover based on hollow pin chain drive, comprising hollow pin chains located on both sides, a plurality of groups of rake teeth are arranged between the hollow pin chains on both sides, each group of rake teeth is composed of two small shafts and a plurality of tooth plates, the tooth plates have a tooth plate head and a tooth plate handle to form an integrated structure, the tooth plate head is a non-left-right symmetrical fan-shaped structure, the tooth plate handle is a long thin plate structure, one end of the tooth plate handle is connected to one end of the tooth plate head to form an integrated structure, the other end of the tooth plate head forms an arc-shaped edge, and two assembly holes are distributed on the tooth plate handle, one of which is arranged near one end of the tooth plate handle. The teeth of each group of rake teeth are distributed in parallel with equal intervals, and a spacer plate is provided between adjacent teeth. Two shaft holes corresponding to the above-mentioned assembly holes are provided on the spacer plate. After the teeth and the spacer plate are aligned, the corresponding and alternately distributed assembly holes and shaft holes form a connected shaft cavity. The above-mentioned two small shafts are respectively provided corresponding to one shaft cavity, and the small shafts are distributed through the shaft cavity. In each group of rake teeth, a gap is formed between the tooth heads of adjacent teeth, and a gap is also formed between the other ends of the tooth handles of adjacent teeth. Between two adjacent groups of rake teeth, the tooth heads of the latter group of rake teeth are located in the gap between the tooth handles of the former group of rake teeth.

[0007] The present invention discloses a grille dirt remover based on hollow pin chain drive, and the technical effects are mainly embodied in the following aspects: 1. A universal hollow pin drive chain is adopted. Since the quality of the chain can be guaranteed, the resistance is small during the transmission process, which not only reduces the power consumption, but also reduces the wear of moving parts, greatly prolongs the service life of the equipment, thereby improving the safety and reliability of the equipment; 2. The maintenance work is reduced, and the equipment maintenance cost is reduced; 3. The new rake tooth structure solves the technical problem of inconvenient maintenance and replacement of rake teeth.
