Description

Technical Field

[0001] The utility model belongs to the technical field of sewage decontamination equipment, and more specifically relates to a flexible sealed backwashing inner-flow type fine grid decontamination machine. Background Art

[0002] The internal inflow fine screen is an efficient and energy-saving solid-liquid separation equipment, which is widely used in urban sewage treatment, industrial wastewater treatment and recycled water treatment. The traditional internal inflow screen plays a key role in water conservancy projects, but when intercepting solid particles, due to the gap between its inner track and the baffles on both sides of the screen body, its sealing effect is not ideal. It often fails due to water flow impact or solid particle accumulation, causing the intercepted objects to enter the downstream treatment system, which brings inconvenience to subsequent treatment. Therefore, a new type of screen structure is needed to improve its sealing performance and interception efficiency.

[0003] After searching, the Chinese patent authorization announcement number is CN204973267U, the announcement date is January 20, 2016, and the name of the invention is: inner diameter flow grid sewage remover. The inner diameter flow grid sewage remover disclosed in the patent document includes a sewage remover body, a sprocket, a guide rail and a filter plate. The guide rail is installed on the side wall of the sewage remover body, and sprockets are installed on both sides of the bottom of the filter plate. The filter plate slides with the guide rail through the sprocket. It also includes a seal. The seal is installed on the guide rail and the width is the same as the distance from the side wall of the sewage remover body to the edge of the filter plate. In the patent document, a seal is set. Through the set seal, the guide rail and the side wall of the sewage remover body can be in a sealed state to a certain extent. Such a structure ensures that when the filter plate filters sewage, the sewage will not flow into the filtered clean water due to the gap between the filter plate and the sewage remover body. However, the seal provided in the patent document is made of synthetic rubber, which has a short service life, is prone to aging, and is easily damaged after long-term wear, thereby affecting the sealing effect. It often needs to be replaced, the equipment is frequently shut down for maintenance, and the cost of decontamination is high. Utility Model Content

[0040] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0041] The utility model is further described below in conjunction with specific embodiments.

[0042] Example 1

[0043] like Figure 1 and Figure 4 As shown, this embodiment provides a flexible sealed backwashing inner flow fine grid decontamination machine, which includes a frame 1 and a driving device 2, a backwashing device 3, a filtering device 4 and a slag outlet 5 installed on the frame 1, wherein the filtering device 4 includes mounting rails arranged on two side plates 19 of the frame 1, and a grid body between the two mounting rails. The grid body includes a plurality of rotating shafts 17 arranged in parallel with each other, and both ends of each rotating shaft 17 are respectively slidably mounted between the corresponding mounting rails through guide wheels 18, and a plurality of rake teeth are arranged on the rotating shaft 17. The driving device 2 drives the sprocket to rotate through a motor, driving the guide wheels 18 on both sides of the filtering device 4 to slide between the mounting rails, thereby driving the entire grid body to rotate, and the rake teeth are used to intercept impurities in the water. The treated sewage flows out from the openings on both sides of the frame 1 through the filter plate, and the impurities on the rake teeth of the grid body automatically fall off after reaching the backwashing device 3 for washing after rotation, and finally discharged from the slag outlet 5.

[0044] The existing internal flow fine screen cleaner is provided with baffles 16 at both ends of the rotating shaft 17. There is a gap between the baffle 16 and the mounting rail. When treating sewage, the sealing is not good, and pollutants can easily escape from the gap, causing pollutants to enter the downstream treatment system, causing inconvenience to subsequent sewage treatment. In this embodiment, a flexible sealing device 11 is installed between the mounting rail of the filter device 4 and the baffle 16, which can achieve a better sealing effect, effectively prevent the leakage of pollutants, and avoid the accumulation of solid particles, thereby significantly improving the operating efficiency and stability of the equipment.

[0045] Specifically, Figure 2 As shown, the flexible sealing device 11 of this embodiment includes a mounting plate 1101 and a brush assembly. One side of the mounting plate 1101 is fixedly mounted on the mounting rail, and the other side thereof is processed with a "concave" groove 1102. One side of the brush assembly is snap-fitted and mounted in the groove 1102, and the other side thereof rests against the baffle 16.

[0046] More optimized, combined Figure 3 and Figure 5-7As shown, the brush assembly includes a brush stem 1103 with a "U"-shaped structure, and bristles 1104 arranged on the brush stem 1103. By adopting this brush assembly for sealing, compared with the use of a rubber strip to fit the baffle 16 in the prior art, the fine bristles can effectively fit on the baffle 16 to form a sealing structure, thereby preventing impurities from escaping from the gap. At the same time, the bristles 1104 are not prone to wear and aging like rubber strips, and the service life of the bristles 1104 is longer, which is beneficial to extend the service life of the sealing device and reduce the frequency of its replacement.

[0047] In addition, if Figure 6 and Figure 7 As shown, the length of the mounting plate 1101 in the present invention matches the length of the vertical section of the "U"-shaped brush stem 1103. When installing the flexible sealing device 11, the brush stem 1103 can be directly clamped in the slot 1102 of the mounting plate 1101 to complete the installation, which is convenient to install.

[0048] like Figure 5-7 As shown, the mounting rails include an outer rail 14 and an inner rail 15 mounted on the side panel 19 of the frame 1, a mounting plate 1101 is disposed between the outer rail 14 and the inner rail 15, and one side of the mounting plate 1101 is mounted and connected to the inner rail 15, and the other side thereof is mounted with a brush assembly via a slot 1102.

[0049] Furthermore, if Figure 4 As shown, the baffle 16 is arranged between the outer guide rail 14 and the inner guide rail 15, and is installed on both sides of the rotating shaft 17. The end of the rotating shaft 17 is slidably installed between the outer guide rail 14 and the inner guide rail 15 through the guide wheel 18. Through the setting of the flexible sealing device 11, an effective seal can be formed between the inner guide rail 15 and the baffle 16, thereby improving the sealing effect of the grille cleaner.

[0050] Example 2

[0051] like Figure 2 and Figure 3 As shown, a flexible sealed backwashing inner-flow fine grid dirt remover of this embodiment has the same main structure as that of embodiment 1, and the difference between it and embodiment 1 is that: the baffle 16 is fixedly installed with a cleaning tooth plate 12 of a "U"-shaped structure near the brush assembly, and the bristles 1104 are embedded in the U-shaped groove of the cleaning tooth plate 12, and the U-shaped groove of the cleaning tooth plate 12 is provided with latch teeth distributed in an array. When the grid body rotates, the baffle 16 drives the cleaning tooth plate 12 to move together, so that the bristles 1104 can be automatically cleaned, and the pollutants wrapped around the bristles 1104 can be automatically scraped off, so as to ensure the cleanliness of the bristles 1104 and extend its service life.

[0052] More optimally, the length of the cleaning tooth plate 12 is smaller than the length of the bristles 1104, and the width of the cleaning tooth plate 12 is also smaller than the width of the bristles 1104. During actual manufacturing, the width of the cleaning tooth plate 12 can be slightly smaller than the bristles 1104, so that the bristles 1104 can be cleaned as much as possible. The length of the cleaning tooth plate 12 can be smaller than the length of the bristles 1104 (mainly the vertical length of the bristles 1104). Since the cleaning tooth plate 12 can rotate with the baffle 16, the entire bristles 1104 can be automatically scraped and cleaned without being set too long, which helps to reduce manufacturing costs.

[0053] Example 3

[0054] like Figure 5 and Figure 8 As shown, the present embodiment is a flexible seal backwash internal flow fine screen cleaner, whose main structure is the same as that of embodiment 2, and the difference between it and embodiment 2 is that it also includes a flushing pipe 13, the pipe wall of the flushing pipe 13 is fixedly mounted on the side plate 19 through a connecting plate 1302, and a spray hole 1303 is opened on the pipe wall of the flushing pipe 13, and the spray hole 1303 is aligned with the bristles 1104 of the brush assembly of the flexible sealing device 11.

[0055] Specifically, one end of the flushing pipe 13 is closed, and the other end thereof is connected to an external water supply device via a flange pipe opening 1301, and the flushing pipe 13 is symmetrically provided with two groups of spray holes 1303 distributed at equal intervals along the length direction of its pipe wall. By providing two groups of spray holes 1303, the flexible sealing device 11 between the outer guide rail 14 and the inner guide rail 15 can be flushed at the same time, and fine particles such as sludge adhered to the bristles 1104 can be effectively flushed, thereby ensuring the cleanliness of the bristles.

[0056] The grille cleaner of this embodiment can be widely used in the fields of sewage treatment, industrial wastewater treatment, etc. It can improve the sealing effect, prevent impurities from leaking, improve the sewage treatment effect, avoid track entanglement, has a simple structure, is easy to use, has high equipment operating efficiency and stability, effectively reduces equipment maintenance costs, and reduces environmental pollution.

[0057] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
