Description

Technical Field

[0001] This utility model relates to a cleaning device, specifically a debris cleaning device for a silo pump, belonging to the field of ash conveying debris cleaning technology. Background Technology

[0002] A silo pump, also known as a bin pump, is a relatively reliable dense-phase dynamic pressure pneumatic conveying device for conveying powdery materials under high pressure (approximately 700 kPa or below). Due to severe corrosion of the ash hopper in the upstream sintering machine and frequent maintenance, there is an excessive amount of debris in the ash hopper. When the ash is conveyed to the silo pump via pneumatic conveying, the debris is also brought into the silo pump. This causes the debris to frequently get stuck in the feeder at the bottom of the silo pump during ash discharge, making the feeder unable to work or even blocking the ash discharge pipe, posing a safety hazard. It is necessary to disassemble the ash silo, which increases the repetitive labor of personnel, increases labor intensity, and is time-consuming and labor-intensive.

[0003] Currently, patent CN221140251U discloses a debris cleaning device for a pneumatic ash conveying system. It describes a cleaning disc on the inner wall of the ash conveying pipe, a cleaning screen on the inner side of the disc, and a rotatable pushing ring connected to the disc. Fine dust particles continue to be conveyed through the gaps in the cleaning screen, while debris mixed in during the conveying process is intercepted by the cleaning screen. The cleaning pipe facilitates the removal of debris intercepted on the screen, improving the efficiency of cleaning debris from the ash conveying pipe. However, it requires a pushing ring to clean the debris on the screen, resulting in a complex structure and high cost. Furthermore, debris may get stuck on the screen during cleaning, leading to incomplete removal.

[0004] Therefore, developing a debris cleaning device for silo pumps that can overcome the above defects has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a debris cleaning device for a silo pump. The device has a simple structure, is easy to use, has low cost, and has a good cleaning effect.

[0006] To solve the above technical problems, this utility model provides a debris cleaning device for a silo pump, which is installed on the silo pump and includes an isolation net and a cleaning component. The isolation net is inclinedly installed inside the silo pump, and the cleaning component is used to clean the surface of the isolation net inside the silo pump. The inclined isolation net has a high end on one side and a low end on the other. A manhole is opened on one side of the silo pump, located at the low end of the isolation net. The cleaning device extends into the silo pump through the manhole to clean the surface of the isolation net.

[0007] The further defined technical solution of this utility model is: Furthermore, in the aforementioned debris cleaning device for the silo pump, the isolation net includes an isolation net body and a fixed side. The isolation net body is adapted to the inner wall of the silo pump, and the fixed side is arranged around the isolation net body. The isolation net body is set on the inner wall of the silo pump through the fixed side.

[0008] Technically, the isolation net body is relatively thin and has a small contact area with the inner wall of the silo pump, which is not conducive to fixed installation. Increasing the contact area by setting a fixed edge is beneficial for fixed connection.

[0009] In the aforementioned debris cleaning device for the silo pump, the manhole door includes a manhole seat and a manhole cover. The silo pump is provided with a manhole seat, which has an inspection manhole. An openable and closable manhole cover is provided at the inspection manhole. The lower end of the manhole cover is hinged to the manhole seat, and the upper end of the manhole cover is locked to the manhole seat through a locking mechanism.

[0010] In terms of technical effect, the manhole door of this utility model does not adopt a left-right opening and closing structure, but adopts a top-bottom opening and closing structure, which can effectively prevent debris from flowing down and causing environmental pollution when the manhole door is opened.

[0011] In the aforementioned debris cleaning device for the silo pump, the lower end of the manhole door is lower than the lower end of the isolation net.

[0012] Technically, the lower end of the manhole door in this invention is lower, which makes it easier for debris to roll directly onto the manhole door after being intercepted by the cleaning net. When the manhole door is opened, it opens from top to bottom. The debris is blocked by the manhole door, placed in the collection bucket, and then discharged. Alternatively, the debris can transition from the manhole door to the collection bucket and be discharged smoothly. If the manhole door is set to the left and right, the debris will be discharged the moment it is opened, which cannot effectively collect and process the debris.

[0013] In the aforementioned debris cleaning device for the silo pump, the cleaning component includes a cleaning rod and a cleaning block disposed at one end of the cleaning rod. The cleaning block has an arc-shaped structure, and magnetic strips are respectively provided on both sides of the cleaning block along its length.

[0014] Technical advantages: This utility model features magnetic strips on both sides of the cleaning block, which facilitate the adsorption of debris scraped off by the cleaning block. At the same time, the cleaning block applies a certain suction force to the debris during cleaning, thus better removing the debris and improving the cleaning effect.

[0015] In the aforementioned debris cleaning device for the silo pump, the magnetic strip is located below the middle part along the width direction of the cleaning block.

[0016] The technical effect depends on the placement of the magnetic strips. If they are too high, they cannot exert their suction power; if they are too low, debris will accumulate and the strips will wear down, causing excess debris to spill out and affecting the efficiency of cleaning.

[0017] In the aforementioned debris cleaning device for the silo pump, the isolation net is made of fiberglass.

[0018] In the aforementioned debris cleaning device for the silo pump, the mesh size of the isolation net is 0.8cm × 0.8cm.

[0019] The beneficial effects of this utility model are: The cleaning device of this utility model uses an isolation net in combination with a cleaning component. The cleaning component does not need to be used every time. The overall structure is simple and the cost is low. The isolation net can be tilted as needed, so that the intercepted debris can slide down the surface of the tilted isolation net to the manhole door and be discharged when the door is opened. It is convenient to use.

[0020] The cleaning component of this utility model consists of a cleaning rod and a cleaning block disposed at one end of the cleaning rod. The cleaning block has an arc-shaped structure and is bent toward the side where the cleaning rod is located. This structure helps to better clean debris from the surface of the isolation net. The debris in the general silo pump is mostly sheet metal, angle iron, etc., so a magnetic strip is added to increase the attraction force and also to attract and carry the debris out of the silo pump, thereby improving the cleaning efficiency.

[0021] This utility model solves the problem of cleaning internal debris without requiring personnel to enter the manhole by using a cleaning component. When there is not much ash in the ash silo pump, the filtered debris in the ash silo can be cleaned, which also greatly reduces the risk of feeder blockage and reduces the rate of repetitive labor for personnel.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them; the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0024] This embodiment provides a debris cleaning device for a silo pump, the structure of which is as follows: Figure 1 As shown, the device is installed on the silo pump 1 and includes an isolation net 2 and a cleaning component. The isolation net 2 is inclinedly installed inside the silo pump 1 and is located in the upper middle part of the silo pump 1. The cleaning component extends into the silo pump 1 through the manhole door 3 to clean the surface of the isolation net 2. Specifically, the results are as follows Figure 1-2 The inclined isolation net 2 shown has a high end on one side and a low end on the other. The isolation net 2 includes an isolation net body 21 and a fixed edge 22. The isolation net body 21 is made of fiberglass, which can reduce the adsorption resistance of the cleaning parts while ensuring service life, and make it easier to adapt to the cleaning parts. The isolation net body is 0.8cm×0.8cm. The appropriate size of the isolation net is selected according to the actual coarseness of the dust on site to ensure that most common debris can be filtered out normally and reduce the situation of the feeder getting stuck. The isolation net body 21 is adapted to the inner wall of the silo pump 1. The fixed edge 22 is fixed around the isolation net body 21. The isolation net body 21 is welded or glued to the inner wall of the silo pump 1 through the fixed edge 22. The fixed edge increases the contact area of ​​the isolation net 2, which is conducive to the fixed connection. Specifically, such as Figure 5-6 As shown, a manhole door 3 is located on one side of the pump 1. The manhole door 3 is situated at the lower end of the isolation net 2, with its lower end lower than the lower end of the net 2. This lower position allows debris to easily roll down to the manhole after being intercepted by the net. When the manhole door is opened, it opens from top to bottom. Debris, blocked by the manhole door, is discharged after the collection bin is placed, or it transitions smoothly from the manhole door into the collection bin for discharge. If the manhole door were set to the left or right, the debris would be discharged immediately upon opening, hindering effective collection and processing. The manhole door 3 includes a manhole seat 31 and a manhole cover 32. The manhole seat 31 is provided on the silo pump 1. The manhole seat 31 has a maintenance manhole. The maintenance manhole is provided with an openable and closable manhole cover 32. The lower end of the manhole cover 32 is hinged to the manhole seat 31. The upper end of the manhole cover 32 is locked to the manhole seat 31 through a locking mechanism in the prior art, so as to complete the opening and closing. In this utility model, a sealing element for sealing is provided between the manhole cover 32 and the manhole seat 31. The sealing element adopts the sealing element of the prior art. Specifically, such as Figure 3-4 As shown, the cleaning component includes a cleaning rod 4 and a cleaning block 5 disposed at one end of the cleaning rod 4. The cleaning block 5 has an arc-shaped structure, and magnetic strips 6 are respectively provided on both sides of the cleaning block 5 along its length direction. The magnetic strips 6 are located below the middle part along the width direction of the cleaning block 5. The magnetic strips on both sides of the cleaning block facilitate the adsorption of debris scraped off by the cleaning block. At the same time, the cleaning block provides a certain suction force to the debris when scraping, so as to better clean the debris and improve the cleaning effect. The setting height of the magnetic strips is limited. If it is too high, it cannot exert its suction force. If it is too low, the debris will accumulate and be easily worn, and excess debris will overflow, affecting the cleaning efficiency.

[0025] In practice: When conveying ash, the ash enters the silo pump 1 and first passes through the isolation screen 2 in the silo pump 1 to filter out impurities. The impurities roll down on the inclined isolation screen 2 to the lower end of the isolation screen 2 and abut against the manhole door 3. When there is not much ash in the silo pump 1, clean the filtered impurities in the ash silo 1. Place a collection bucket at the manhole door 3 and open the manhole door 3 from top to bottom. The impurities fall into the collection bucket. It can be observed from the manhole door 3. If there are residual impurities on the surface of the isolation screen 2, the cleaning device is inserted into the silo pump 1 through the manhole door to push and pull the impurities on the surface of the isolation screen 2. After prying, the impurities roll out directly or are adsorbed by the cleaning block 5, which improves the efficiency of cleaning and reduces the risk of feeder blockage.

[0026] In addition to the embodiments described above, this utility model may have other implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the protection scope claimed by this utility model.
