Description

Sewage slag removal device

Technical Field

The utility model relates to the field of sewage treatment, in particular to a sewage slag removal device.

Background

In many industrial processes, such as petrochemical, chemical, pharmaceutical, food processing, etc., wastewater treatment areas play a critical role in the treatment of wastewater produced during the process. However, various kinds of sludge such as sediment, solid particles, oil scale, etc. are easily generated in the sewage treatment area during the treatment. These residues can adhere to equipment surfaces, interfere with the proper functioning of the wastewater treatment, and may even cause serious consequences such as equipment blockage, damage, and production interruption. Therefore, it is necessary to periodically clean up the sludge in the sewage treatment area and collect it for further treatment.

Although the existing slag removal equipment solves the problem of cleaning the sewage treatment area to a certain extent, some defects still exist. Chinese patent CN202087123U discloses rotatory sewage deslagging equipment, and this sewage deslagging equipment adopts drum-type mesh screen structure, realizes the filtration of sewage and the discharge of residue through rotatory mesh screen, has effectively solved the demand of arranging sediment, has improved sewage treatment equipment's performance. However, this structure has some problems. First, the residue tends to adhere to the inside of the mesh screen, causing clogging of the mesh screen, affecting the filtration efficiency and increasing the loss of the mesh screen. In addition, the manner of filtering the sewage by means of the rotation of the drum screen cannot sufficiently agitate the sewage in the screen, which also affects the filtering efficiency and increases the abrasion of the screen, thereby increasing the sewage treatment cost. In response to these problems, there is a need for an improved optimization of the apparatus to increase filtration efficiency, reduce the wear of the mesh screen, and reduce the cost of processing.

Disclosure of Invention

The utility model aims to provide a sewage deslagging device, which aims to solve the problems of poor treatment effect and high treatment cost caused by low filtration efficiency in the sewage deslagging process.

The basic scheme provided by the utility model is as follows: a sewage slag removal device, comprising the following parts: the slag blocking gate, the speed reducer, the slag removing device body and the water tank are characterized in that the slag blocking gate adopts a vertically installed flat iron grid structure; a roller brush, a carding knife and a slag storage box are arranged in the slag removing device body, wherein the roller brush is made of hard fibers; the carding knives are arranged at equal intervals along the axis of the roller brush and are fixedly connected to the inner wall of the slag storage box far away from the slag blocking gate.

In the working process of the slag removing device, in the initial state, the slag blocking gate is in a closed state, and the speed reducer and the roller brush stop running. When the dregs in the sewage area need to be cleaned, the dreg blocking gate is opened, and the working flow is started. Along with the rising of the slag blocking gate, the speed reducer is started and is transmitted to the roller brush, so that the roller brush starts to rotate. The rotating drum brush cleans the wall surface of the sewage area of the dregs by friction force, and the dregs are then brushed down and attached to the bristles of the drum brush.

As the drum brush rotates, the residue attached thereto moves to the position of the comb blade. The carding knife is arranged below the roller brush, scrapes the dregs and drops the dregs into the dreg storage box. When the cleaning is completed, the slag blocking gate is closed, and the speed reducer and the roller brush stop running. After the dregs have accumulated in the dregs storage tank for a period of time, the dregs can be washed by a water discharge tank and sent to a squeezer or other processing equipment for further processing. In this way, the roller brush can be kept clean all the time and can continuously and effectively clean dregs in sewage. The whole working process realizes efficient dreg cleaning and treatment, and improves the sewage treatment effect.

The beneficial effects of the utility model are as follows:

1. the filtering efficiency and the slag removing effect are improved.

The existence of the slag blocking gate of the vertical flat iron grid bars can prevent larger particles and impurities from entering the system, so that the filtering effect and the blocking capability of the slag blocking gate are improved, and the risks of damage and blockage to subsequent treatment equipment are reduced; the rotary motion of the roller brush can effectively clean solid particles, suspended matters and other impurities attached to the wall surface of the sewage area, and the filtering effect and the purification degree of water quality are improved; the cutting edge of the carding knife scrapes the dregs on the roller brush, prevents dregs from accumulating and attaching, keeps the cleaning state of the roller brush, ensures that the roller brush continuously and efficiently cleans the dregs in sewage, and further improves the filtering efficiency and prevents dirt from remaining. The combination of the operations can keep the cleaning state of the roller brush, ensure that the roller brush continuously and effectively cleans sewage, and improve the filtering efficiency and the slag removal effect.

2. The sewage treatment cost is reduced.

The roller mechanism is simple, and the material of the roller brush is made of hard fibers, so that the roller brush has higher durability and service life, and can withstand water impact and abrasion when contacting with dregs, thereby maintaining the stability and durability of the cleaning effect. This also reduces the frequency of replacement and maintenance of the roller brush, saving maintenance costs and working time. The equidistant arrangement of the carding knives can ensure that each carding knife can uniformly scrape dregs and attachments when the roller brush rotates, so that the contact area with the roller brush can be increased, particles and dirt in sewage can be effectively removed, and the cleaning effect is improved; meanwhile, through equidistant arrangement, the carding knives can be uniformly distributed on the roller brush, so that cleaning work is uniformly shared on each carding knife, excessive concentration on certain carding knives is avoided, the load of the single carding knife is reduced, and the service life of the single carding knife is prolonged. At the same time, when replacement is required, maintenance personnel can easily disassemble and replace these components without performing complicated operations or using specialized tools. The device is simple in structure and easy to maintain, and maintenance personnel need relatively less time and effort in the maintenance process.

Further, the gap between the vertically installed flat iron bars is 50mm.

Smaller gaps can be more easily blocked by solid particles and impurities, obstruct the normal flow of sewage, and even cause the blockage of the device; and too large a gap may not be able to block larger solid particles and impurities, allowing them to enter subsequent processing equipment, reducing the filtration effect.

The beneficial effect of this scheme is: the sizes of the solid particles and the impurities are precisely controlled, so that finer filtering and separating effects are realized, and the best filtering effect and performance of the device are ensured.

Further, the carding blade may be provided with grooves.

The beneficial effect of this scheme is: the existence of the groove can increase the contact area and the scraping force of the carding knife, and meanwhile, dregs in the groove are relatively easy to clean, difficult to adhere and accumulate, and the frequency of maintenance and cleaning is reduced. Therefore, time and labor cost can be saved, and the operation efficiency is improved.

Further, carding knives are arranged on the inner wall of the slag storage box in a staggered manner.

In the staggered arrangement, the locations of the comb knives are no longer equidistant along the axis of the roller brush, but are arranged in an offset manner. Specifically, the staggered arrangement staggers the positions of the carding knives so that a certain interval exists between adjacent carding knives. For example, if a lateral arrangement is used, the first row of comb knives is located at a particular position on the roller brush, while the second row of comb knives is located at an adjacent lateral position, and so on. Such a staggered arrangement may form an alternating pattern.

The beneficial effect of this scheme is: the arrangement mode can increase the contact area between the carding knife and dregs, reduce accumulation and blockage, and improve the working efficiency and reliability of the device.

The following is a further detailed description of the embodiments:

example 1

The sewage slag removal device shown in fig. 1 and 2 comprises the following components: a slag blocking gate 01, a speed reducer 02, a slag removing device body 03 and a water tank 07. The slag blocking gate 01 adopts a vertically installed flat iron grid structure, and is concretely implemented as follows:

slag blocking gate 01: the inlet of the slag removing device body 03 consists of vertically installed flat iron bars. The gap between the bars of the flat iron in this example was set to 50mm to screen out larger solid particles and impurities from entering the slag removal device.

Speed reducer 02: is used for providing power transmission and starting and driving the slag removing device to operate. The speed reducer 02 transmits power to the roller brush 04 in the slag removing device body 03, and starts to operate.

Slag removal device body 03: comprising a roller brush 04, a carding knife 05 and a slag storage tank 06.

The roller brush 04 is made of hard fibers and is located inside the slag removing device body 03. The hard fiber drum brush 04 is a core component of the slag removing device and is made of hard fiber materials. The drum brush 04 rotates and contacts the wall surface of the sewage area by the transmission of the speed reducer 02, and removes the dregs adhering to the sewage area by the action of friction force, brushes down and collects the dregs.

Carding knife 05: the carding knives 05 are arranged at equal intervals along the lower part of the axis of the roller brush 04 and are fixedly connected to the wall surface of the slag storage tank 06 through bolts. The carding knife 05 is positioned below the roller brush 04 and away from the slag blocking gate 01. Its function is to scrape off the dregs on the roller brush 04 and make it drop into the dregs storage tank 06.

Slag storage tank 06: for collecting the residue scraped from the roller brush 04 and the comb blade 05 during cleaning.

Sink 07: the water tank 07 is located behind the slag storage bin 06, along the axis of the roller brush 04, and away from the speed reducer 02. Specifically, the water tank 07 is located below the slag removal device body 03, and is connected to the slag storage tank 06 for water flushing and further processing. After a period of accumulation, the water is discharged through a water tank 07 for further treatment by flushing into a squeezer or other treatment equipment.

Specifically: in the operation process of the slag removing device, in the initial state, the slag blocking gate 01 is closed, and the speed reducer 02 and the roller brush 04 are in a stop state. When it is desired to clean the sewage area of dregs, a workflow is started. The slag lock 01 is opened, and the speed reducer 02 starts to operate and is driven to the roller brush 04 to start rotating. The rotating roller brush 04 thoroughly removes the residue attached to the wall surface by friction with the wall surface of the sewage area. These dregs are brushed down and attached to the bristles of the roller brush 04.

As the drum brush 04 rotates, the residue attached to the bristles moves to the position of the comb blade 05. The carding knife 05 is positioned below the roller brush 04 and plays a role in scraping dregs so that the dregs fall into the dreg storage box 06. Once the cleaning is completed, the slag lock 01 is closed, and the speed reducer 02 and the roller brush 04 are stopped. After a certain period of operation, the dregs accumulated in the dregs storage tank 06 can be washed by water, and then further sent to a squeezer or other processing equipment for processing through a water tank 07. Through this working process, the roller brush 04 can be kept clean all the time and continuously and effectively clean the dregs in the sewage. The whole process realizes efficient slag cleaning and treatment, and the sewage treatment effect is remarkably improved.

Through the working flow, the slag removing device can effectively remove slag in the sewage area and collect the slag in the slag storage tank 06 so as to ensure smooth and normal operation of the pipeline. The process can be circularly operated according to the requirement, the dregs are cleaned regularly, and the efficient operation of the equipment is maintained.

Example two

The difference between this embodiment and the first embodiment is that: the carding blade 05 is provided with grooves.

The method comprises the following steps: the grooves are provided at the scum scraping edge of the carding blade 05 for increasing the effect of scum scraping. As the roller brush 04 rotates and brushes down the dross, the flutes may better collect and guide the dross, making it easier to drop into the dross storage bin 06.

The design of the grooves helps to improve the cleaning effect of the carding blade 05, especially for some small or stuck dregs particles on the cylinder brush 04. By the guiding action of the grooves, these residues can be scraped off and collected more effectively, reducing the possibility of residues and accumulating on the roller brush 04. Meanwhile, the arrangement of the grooves is also beneficial to reducing overflow and pollution of dregs, and the operation performance and cleaning efficiency of the whole dreg cleaning device are improved.

Example III

The difference between this embodiment and the first embodiment is that: the staggered carding knives 05 are adopted to improve the slag scraping effect and the cleaning capability of the roller brush 04.

In the embodiment, the carding knives 05 are fixedly connected to the inner wall of the slag storage tank 06 far away from the slag blocking gate 01 in a staggered arrangement along the axis of the roller brush 04. The staggered carding blades 05 can scrape off the dregs on the roller brush 04 more effectively, and prevent the dregs from accumulating on the roller brush 04.

The main purpose of the staggered arrangement is to optimize the working efficiency and the slag removing effect of the slag removing device. By the staggered arrangement, the carding blade 05 can better cover the surface of the roller brush 04, increasing the contact area and opportunity with the dregs. In this way, the carding blade 05 can cover a wider area when scraping dregs, thereby improving cleaning efficiency and thoroughness.

In addition, the staggered arrangement also helps to reduce the accumulation and jamming of dregs between the carding knives 05. Through the dislocation arrangement, the interval between the carding knives 05 can make the dregs drop more easily in the dregs storage tank 06, reduces the possibility of piling up, avoids too much dregs to adhere to the carding knives 05 to keep the normal operation of the device.
