Description

Technical Field

[0001] The utility model relates to the field of rainwater treatment, in particular to a grille machine for municipal rainwater treatment. Background Technique

[0002] A grille machine for municipal rainwater treatment is mainly used to intercept and remove larger-sized solid pollutants such as branches, plastic bags, and fallen leaves mixed in municipal rainwater to prevent subsequent treatment equipment from being blocked or worn. This device usually includes structures such as a frame, a driving device, and a grille rake tooth assembly. The driving device drives the rake tooth assembly to reciprocate or rotate on the grille bars, thereby lifting and transporting the debris intercepted on the grille to a designated position for cleaning. It has the characteristics of high automation, good interception efficiency, and convenient maintenance, and can realize the preliminary purification treatment of municipal rainwater, providing good pretreatment conditions for subsequent processes such as sedimentation and filtration.

[0003] In the prior art, the Chinese invention with the publication number CN120001106A discloses a rotary grille machine for the preliminary treatment of municipal rainwater. It controls the grille plate to rotate from a vertical state to a horizontal state through the cooperation of gears and racks to ensure that impurities fall into the sewage discharge tank, and improves the cleaning efficiency of the sponge and the grille plate through a transmission component. However, it is found in the use of such devices that most grille machines separate impurities in water by means of filter hooks. When cleaning the hooks, due to the diversity of impurities in the sewage, impurities such as fluff will entangle in the hooks or grille gaps, and even by pouring, it is impossible to quickly and effectively clean the hooks on the grille, thus affecting the subsequent working process.

[0031] The present invention will be further described below with reference to the accompanying drawings:

[0032] As Figures 1 - 10As shown in the figure, a grille machine for municipal rainwater treatment includes a support mechanism 1 for enhancing support and a power mechanism 2 for enhancing power. A separation mechanism 3 is installed on the support mechanism 1, and the power end of the separation mechanism 3 is connected to the power mechanism 2. It also includes a dislocation mechanism 6 for assisting in separating impurities of the separation mechanism 3, an extrusion mechanism 4, and a reset mechanism 5 for cooperating with the dislocation mechanism 6. The separation mechanism 3 includes filter chain plates 31, connecting shafts 32, and filter hooks 33. The filter hooks 33 are connected to the connecting shafts 32 through the dislocation mechanism 6, and the filter chain plates 31 are connected to each other through the connecting shafts 32. The reset mechanism 5 is arranged outside the filter chain plates 31, and the extrusion mechanism 4 is installed at the corresponding position of the reset mechanism 5. A blow separation mechanism 7 is arranged at the discharge end of the separation mechanism 3 inside the support mechanism 1;

[0033] A number of filter chain plates 31 and filter hooks 33 are arranged alternately on the same connecting shaft 32. The dislocation mechanism 6 includes a torsion sleeve 61, a fixed sleeve 62, and a torsion groove 63. The filter hook 33 is fixedly connected to the torsion sleeve 61. The fixed sleeve 62 is rotatably connected to the inside of the torsion sleeve 61. A limit block 64 is arranged on the outer cylindrical surface of the fixed sleeve 62 corresponding to the inner wall of the torsion sleeve 61. A torsion groove 63 is arranged on the inner wall of the torsion sleeve 61 corresponding to the limit block 64. The torsion groove 63 is an inclined groove, and the inclination directions of the torsion grooves 63 on adjacent torsion sleeves 61 are opposite. The fixed sleeve 62 is fixedly connected to the connecting shaft 32.

[0034] In this embodiment, the connecting shaft 32 and the fixed sleeve 62 are axially slidably connected to the torsion sleeve 61. A mating ball head 42 of the extrusion mechanism 4 is fixedly connected to the top of the connecting shaft 32. The extrusion mechanism 4 further includes an extrusion slide rail 41 and an extrusion block 43. The extrusion slide rail 41 is installed inside the support mechanism 1 near the discharge port of the support mechanism 1. The mating ball head 42 and the connecting shaft 32 are slidably connected to the inside of the extrusion slide rail 41. The extrusion block 43 is formed in the groove on the extrusion slide rail 41.

[0035] In this embodiment, the blow separation mechanism 7 is installed at the corresponding position of the extrusion slide rail 41.

[0036] In this embodiment, the reset mechanism 5 includes a sealing sleeve 51, a reset spring 52, and a retaining ring 53. The sealing sleeve 51 is fixedly connected to one end of the filter chain plate 31 corresponding to the mating ball head 42. A reset spring 52 is arranged inside the sealing sleeve 51. A retaining ring 53 is fixedly connected to the connecting shaft 32 inside the sealing sleeve 51. The retaining ring 53 is located on one side of the mating ball head 42, ensuring that the cooperation between the mating ball head 42 and the connecting shaft 32 performs axial movement and rapid reset under the support of the retaining ring 53 and the reset spring 52.

[0037] In this embodiment, under the restriction of the limit block 64 and the torsion groove 63, the relative rotation angle of the filter hook 33 with respect to the connecting shaft 32 is 0° - 10°.

[0038] In this embodiment, as Figure 8 shown, there are two limiting blocks 64 symmetrically arranged with respect to the axis of the fixed sleeve 62, and there are two torsion grooves 63 corresponding to the limiting blocks 64.

[0039] In this embodiment, as Figure 3 shown, the blowing and separating mechanism 7 includes a nozzle holder and a gas source pipe, and the blowing direction of the nozzle holder is obliquely downward.

[0040] Working principle: When using the device, the lower end of the support mechanism 1 is immersed in water, and the other end corresponds to an external collection box (not shown). The gas source pipe of the blowing and separating mechanism 7 is connected to an external gas source. When the driving mechanism 2 drives the separating mechanism 3 to be transported as a whole, at this time, because the return spring 52 supports the retaining ring 53 and the coupling shaft 32, the coupling shaft 32 cannot move axially. At this time, the filtering hook 33 will not twist, and the impurities in the sewage are separated and gradually transported upward;

[0041] After the impurities are separated and transported until they reach the separation position, most of the impurities will fall due to gravity, and some will be wound around the filtering hook 33. At this time, the mating ball head 42 is squeezed by the squeezing block 43 inside the squeezing slide rail 41, prompting the coupling shaft 32 to move axially. When the coupling shaft 32 moves, the coupling shaft 32 drives the fixed sleeve 62 to move axially. The limiting block 64 on the fixed sleeve 62 squeezes the torsion groove 63 on the torsion sleeve 61, causing the torsion sleeve 61 to drive the filtering hook 33 to twist, and the twisting directions of the adjacent filtering hooks 33 are opposite (as Figures 6 to 7 shown in the change), then the impurities are torn apart. During this process, a small part of the impurities are torn apart and fall. When the mating ball head 42 passes over the squeezing block 43, the return spring 52 will support the retaining ring 53, the coupling shaft 32, the fixed sleeve 62, and the limiting block 64 to quickly reset. And with the blowing of the blowing and separating mechanism 7, gaps are generated in the openings between the impurities, so as to ensure that the impurities fall due to vibration and blowing, ensuring the cleaning of the filtering hook 33 and providing guarantee for subsequent continuous separation.

[0042] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
