Description

Technical Field

[0001] The utility model relates to the field of wastewater treatment equipment, in particular to food wastewater treatment and reclaimed water recycling equipment. Background Art

[0002] Dissolved air food wastewater treatment equipment is a highly efficient equipment that uses dissolved air technology to treat food industry wastewater. Its main purpose is to remove suspended matter, grease and organic matter in the wastewater so that the wastewater can meet the reuse standard.

[0003] The equipment first pre-treats food wastewater to remove large particles and some suspended matter, and then enters the water inlet bin to homogenize the water quality and water volume, and then is pumped into the treatment bin. The treatment bin is equipped with an air dissolving device to evenly disperse air or oxygen into the wastewater in the form of tiny bubbles. The tiny bubbles can adhere to the suspended matter and grease in the food wastewater, turning them into flocs with a smaller specific gravity. The flocs with a smaller specific gravity float to the water surface and are removed to the scum bin by a scraper device. The precipitated sludge is pumped to the sludge recovery system by the sludge pump, and the treated reclaimed water can be recycled for utilization.

[0004] When the existing scraper is working on the scum, it mainly plays a pushing role on the scum, which makes it easy for the scum to continue to adhere to the scraper. When the scraper moves to the top through the transmission chain, the remaining scum slides down and easily falls to the top of the next group of scrapers. Most of the existing scrapers are combined, and there is no blocking structure on the beam, which makes it easy for the fallen scum to consolidate at the connection between the beam and the scraper and other structural parts. Due to the large number of gaps, the consolidation force is large, which makes it difficult to clean and disassemble later. Utility Model Content

[0019] The technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0020] Examples, such as Figure 1-Figure 3 As shown: The utility model provides a food wastewater treatment and reclaimed water reuse equipment, the structure of which includes an equipment body 1, the equipment body 1 is divided into a water inlet bin 1a, a treatment bin 1b and a scum bin 1c by a plate, and transmission chains 2 are arranged on both sides above the treatment bin 1b, the transmission chain 2 is tightened by two front and rear sprockets, so that the motion track of the transmission chain 2 includes a straight track and an arc track, the transmission chain 2 is driven to rotate by a transmission device, such as a motor drives the sprocket to rotate, and the axis of the sprocket is arranged horizontally, so that the straight track is arranged in the upper and lower layers;

[0021] A plurality of scraper assemblies 3 are provided on the transmission chain 2, and usually two of them are provided to scrape the scum on the liquid surface at the top of the processing bin 1b in turn. The top of the plate separating the processing bin 1b and the scum bin 1c is inclined and inclined toward the scum bin 1c. The inclined portion of the top of the plate separating the processing bin 1b and the scum bin 1c is set as an auxiliary slope 1d. The liquid level of the liquid in the processing bin 1b is within the horizontal height range of the auxiliary slope 1d. The scraper assemblies 3 are used to push the scum on the top of the liquid surface and scrape the scum into the scum bin 1c through the auxiliary slope 1d.

[0022] The scraper assembly 3 includes a crossbeam 32 connected to the transmission chains 2 on both sides through a connecting piece 31. The connecting piece 31 is an angle steel sheet or other fasteners connected to the chain-type transmission chain 2. An upper baffle 34 and a lower scraper 33 are respectively provided at the upper and lower ends of the crossbeam 32. The upper baffle 34 is used to block the materials that bounce up and fall from another scraper assembly 3 to avoid consolidation on the crossbeam 32 and being difficult to clean. Therefore, the required width of the upper baffle 34 projected on the horizontal plane is greater than the width of the crossbeam 32 projected on the horizontal plane. In this embodiment, the upper baffle 34 and the lower scraper 33 are elastically connected on the crossbeam 32 and have the freedom to swing backward. Naturally, there will be an elastic tendency to reset forward after swinging backward. The forward and backward mentioned here are the working directions of the scraper assembly 3 and the trajectory directions of the transmission chain 2.

[0023] For elastic connection, an elastic connection plate 35 is installed on the cross beam 32, which can be an iron plate, a steel plate or a composite plate of metal and rubber, or a structure of a plurality of iron plates and steel plates. It is only necessary to achieve the effect that the upper and lower ends can be elastically deformed backward and reset based on the cross beam 32. The elastic connection plate 35 is vertically arranged, and the upper baffle plate 34 and the lower scraper plate 33 are respectively installed at the upper and lower ends of the elastic connection plate 35 to be elastically connected to the cross beam 32.

[0024] Subsequently, a blocking structure is provided in the main body 1 of the equipment, specifically at the top of the processing bin 1b and the scum bin 1c, for blocking the upper baffle 34 and the lower scraper 33 so that the two undergo elastic deformation. The blocking structure is a rod movably installed in the main body 1 of the equipment, and the rod retains the freedom to rotate around an axis set in its length direction in the main body 1 of the equipment. In this embodiment, the blocking structure includes a first blocking beam 11 and a second blocking beam 12, wherein the upper baffle 34 includes a front baffle surface 34a and an upper baffle surface 34b, the front baffle surface 34a is bent backward on the upper baffle structure, and the upper baffle surface 34b is extended upward at the end of the bending of the front baffle surface 34a. The first stop beam 11 is provided in the direction of the straight track close to the slag bin 1c. The first stop beam 11 is located on the upper stop surface 34b on the moving path of the straight track and is used to block the upper baffle 34, so that it deforms backwards when moving until it is out of contact with the first stop beam 11. A more accurate implementation method is to make the upper stop surface 34b contact the first stop beam 11; a second stop beam 12 is provided in the slag bin 1c behind the auxiliary inclined surface 1d, and the second stop beam 12 is located on the moving path of the lower scraper 33 on the arc track and is used to block the lower scraper 33, so that it deforms backwards when moving until it is out of contact with the second stop beam 12;

[0025] Since the upper baffle 34 and the lower scraper 33 are elastically connected on the cross beam 32, they will rebound to the front end after breaking away from the restrictions of the first baffle beam 11 and the second baffle beam 12, and the materials remaining on the upper baffle 34 and the lower scraper 33 will be ejected. The equipment body 1 is provided with a plate with a height higher than the transmission chain 2 on the back of the slag bin 1c. The plate is located in the direction of the pop-up and reset of the upper baffle 34 and the lower scraper 33, and is used to block the objects that are ejected from the upper baffle 34 and the lower scraper 33 that have been elastically reset after breaking away from the first baffle beam 11 or the second baffle beam 12.

[0026] During the specific implementation, the equipment body 1 treats the food wastewater in a manner known in the prior art, and produces scum at the top of the liquid surface. The motor drives the sprocket to rotate, and the transmission chain 2 on the sprocket drives the crossbeam 32 to move on the processing bin 1b. The lower scraper 33 extends below the liquid surface of the processing bin 1b, and drives the scum on the liquid surface during the movement. After being driven to the auxiliary inclined surface 1d, the lower scraper 33 scrapes the scum on the auxiliary inclined surface 1d into the scum bin 1c. In this process, the upper baffle surface 34b of the upper baffle plate 34 contacts the first baffle beam 11, causing the upper baffle plate 34 to deform backwards. If there is scum or other materials on the upper baffle surface 34b, they will pass through the first baffle beam 11. The guard beam 11 scrapes the scum and drops it into the water, waiting for the next drive of the lower scraper 33. At this time, the lower scraper 33 has not reached the auxiliary inclined surface 1d. When the lower scraper 33 reaches the auxiliary inclined surface 1d, the upper baffle surface 34b of the upper baffle 34 separates from the first guard beam 11, and resets and rebounds to eject the material on the front baffle surface 34a and drop it into the scum bin 1c or on the plate. Subsequently, after the lower scraper 33 separates from the auxiliary inclined surface 1d, it contacts the second guard beam 12 behind the auxiliary inclined surface 1d. At this time, the lower scraper 33 makes an upward circular motion along the trajectory of the transmission chain 2. After the lower scraper 33 separates from the second guard beam 12, it resets and rebounds to eject the material from the lower scraper 33 and drop it into the scum bin 1c or on the plate.

[0027] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
