Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, specifically to an industrial wastewater pretreatment device. Background Technology
[0002] Wastewater pretreatment refers to the front-end treatment process that removes pollutants that are detrimental to subsequent treatment from wastewater and optimizes water quality and quantity conditions before the wastewater enters core units such as biological treatment and advanced treatment. This is achieved through physical, chemical, or simple physicochemical methods.
[0003] Because wastewater contains a lot of impurities of different types, such as hair and fibers, the length of these impurities is usually greater than the sieve aperture and they cannot pass through the sieve. They are also tough and will wrap around the sieve bars or the edge of the sieve aperture, forming a fiber web. The fine impurities that flow through later will be trapped by this web, which will gradually thicken to form a dense interception layer and eventually block the sieve aperture, affecting the treatment effect.
[0004] In view of this, the present invention provides an industrial wastewater pretreatment device to solve the above-mentioned technical problems. Utility Model Content
[0005] To address the shortcomings of the aforementioned background technology, this utility model provides a technical solution for an industrial wastewater pretreatment device, which solves the problems mentioned in the background technology.
[0006] This utility model provides the following technical solution: an industrial wastewater pretreatment device, including a frame, a filter cylinder with a rotatable impurity removal function supported on the top of the frame, a gear I fixed to the outside of one end of the filter cylinder, a motor installed on the top of the frame, and a gear II installed on the drive end of the motor, characterized in that: wastewater flows into the interior of the filter cylinder from the direction of the gear I, and the motor drives the gear II to rotate and mesh with the gear I to drive the filter cylinder to rotate and filter and clean the impurities contained in the wastewater;
[0007] The inner wall of the filter cartridge is provided with an anti-clogging mechanism, which includes a collection seat for collecting impurities and a scraping component for removing impurities filtered inside the filter cartridge. The collection seat has a rotating auger that pushes the material. The top side of the collection seat has an installation cavity. The end of the collection seat is connected to a discharge port. The scraping component is located inside the installation cavity. The end of the auger is connected to an existing drive unit. The existing drive unit drives the auger to rotate, pushing the impurities collected inside the collection seat to the discharge port at the end and then discharging them.
[0008] As a preferred technical solution of this utility model, the scraping component includes a scraper rod, which is detachably and slidably installed inside the mounting cavity. The top of the scraper rod is a brush structure and is in close contact with the inner wall of the filter cartridge, so that when the filter cartridge rotates, the impurities filtered inside are scraped off by the brush on the top of the scraper rod, and the sieve holes on the surface of the filter cartridge are always kept unobstructed.
[0009] As a preferred technical solution of this utility model, the inner sides of the mounting cavity are fixed with limiting locking blocks, the scraper is provided with C-shaped slots on both sides, and the end of the locking block is an arc surface structure.
[0010] As a preferred technical solution of this utility model, a rotating wheel is rotatably connected inside the slot, an extension block is slidably connected inside the engaging block, and the end of the scraper bar corresponds to the arc surface structure of the engaging block through the slot and then moves in the direction of gear I through the engagement of the slot and the extension block, so as to detachably slide and install it inside the mounting cavity. This allows for disassembly and replacement when the top of the scraper bar is worn or has too much accumulated impurities and lint, so as to avoid affecting the subsequent cleaning effect.
[0011] As a preferred technical solution of this utility model, a sliding groove is provided at the bottom of the slot, and a spring is embedded inside the sliding groove. The bottom of the rotating wheel extends into the sliding groove and is connected to the end of the spring. Through the arc surface structure of the end of the locking block and the setting of the rotating wheel, the scraper first contacts the locking block at its end during installation and then slides towards gear I. When the rotating wheel contacts the locking block, it moves towards the middle position of the scraper due to the deformation and expansion of the spring, avoiding obstruction between the end of the scraper and the locking block during installation. At the same time, the rotating wheel can rotate, so that the scraper can rotate by friction generated by the contact between the rotating wheel and the locking block during sliding, which can reduce the wear between the locking block and the rotating wheel, avoid jamming of the scraper during sliding installation, and ensure the smoothness of the scraper during sliding.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] 1. The scraper removes impurities by scraping the top of the scraper, ensuring that the screen holes on the surface of the filter cartridge remain unobstructed during the rotation of the filter cartridge, preventing them from being blocked by impurities. The scraped-off impurities fall into the inside of the collection seat, and then the auger rotates inside the collection seat to push the impurities towards the discharge port of the collection seat, cleaning the inside of the collection seat and preventing excessive accumulation of impurities from affecting the subsequent discharge space of impurities.
[0014] 2. The engagement of the slot and the extension block causes the extension block to move in the direction of the scraper rod's displacement, ensuring that there is always a connecting link between the engaging block and the scraper rod. This prevents the scraper rod from derailing from the engaging block on one side when it moves excessively, thus affecting its use. Attached Figure Description

[0022] 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 some embodiments of the present utility model, and not all embodiments. 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.
[0023] Please see Figure 1-6 As shown, an industrial wastewater pretreatment device includes a frame 1, a filter cylinder 2 with a rotatable impurity removal function supported on the top of the frame 1, a gear I 201 fixed to the outside of one end of the filter cylinder 2, a motor installed on the top of the frame 1, and a gear II installed on the drive end of the motor. The device is characterized in that: wastewater flows into the filter cylinder 2 from the direction of gear I 201, and the motor drives gear II to rotate and mesh with gear I 201, thereby driving the filter cylinder 2 to rotate and filter and clean the impurities contained in the wastewater.
[0024] The inner wall of the filter cartridge 2 is provided with an anti-clogging mechanism, which includes a collection seat 3 for collecting impurities and a scraping component for removing impurities filtered inside the filter cartridge 2. The collection seat 3 is equipped with a auger 303 that pushes the material inside. The top side of the collection seat 3 is provided with an installation cavity 302. The end of the collection seat 3 is connected to a discharge port. The scraping component is located inside the installation cavity 302. The end of the auger 303 is connected to an existing drive unit. The existing drive unit drives the auger 303 to rotate, pushing the impurities collected inside the collection seat 3 to the discharge port at the end and then discharging them.
[0025] As a specific embodiment of this utility model, the scraping component includes a scraper 301, which is detachably and slidably installed inside the mounting cavity 302. The top of the scraper 301 is a brush structure and is in close contact with the inner wall of the filter cartridge 2, so that when the filter cartridge 2 rotates, the impurities filtered inside are scraped off by the brush on the top of the scraper 301, and the sieve holes on the surface of the filter cartridge 2 are always kept unobstructed.
[0026] As a specific embodiment of this utility model, the inner sides of the mounting cavity 302 are fixed with limiting locking blocks 3011, and the scraper rod 301 has C-shaped slots 3013 on both sides. The ends of the locking blocks 3011 are arc-shaped.
[0027] As a specific embodiment of this utility model, a rotating wheel 3012 is rotatably connected inside the slot 3013, and an extension block 3014 is slidably connected inside the engaging block 3011. The end of the scraper 301 corresponds to the arc surface structure of the engaging block 3011 through the slot 3013, and then moves towards the gear I 201 through the engagement of the slot 3013 and the extension block 3014, so that it can be detachably and slidably installed inside the mounting cavity 302. This allows for disassembly and replacement when the top of the scraper 301 is worn or has accumulated too much impurities and lint, so as to avoid affecting the subsequent cleaning effect.
[0028] In one specific embodiment of this utility model, a sliding groove 3016 is provided at the bottom of the slot 3013. A spring 3015 is embedded inside the sliding groove 3016. The bottom of the rotating wheel 3012 extends into the sliding groove 3016 and is connected to the end of the spring 3015. Due to the arc-shaped structure at the end of the engaging block 3011 and the arrangement of the rotating wheel 3012, the scraper 301 first contacts the engaging block 3011 at its end during installation and then slides towards the gear I 201. The rotating wheel 3012, when in contact with the engaging block... When 3011 contacts, the spring 3015 deforms and expands to move towards the middle position of the scraper 301, avoiding obstruction between the end of the scraper 301 and the locking block 3011 during installation. At the same time, the rotating wheel 3012 can rotate, so that the scraper 301 can rotate by friction generated by the contact between the rotating wheel 3012 and the locking block 3011 during sliding. This reduces the wear between the locking block 3011 and the rotating wheel 3012, avoids jamming of the scraper 301 during sliding installation, and ensures the smoothness of the scraper 301 during sliding.
[0029] Wastewater enters the interior of filter cylinder 2 through gear I 201. Then, the filter cylinder 2 rotates to filter and remove impurities from the wastewater. Scraper 301 is detachably installed on the top of the collection base 3. The brush part on the top is in close contact with the inner wall of the filter cylinder 2, so that when the filter cylinder 2 rotates, the impurities filtered down the inner wall are scraped off by the top of scraper 301. This ensures that the screen holes on the surface of the filter cylinder 2 remain unobstructed when it rotates and filters, preventing them from being blocked by impurities. The scraped-off impurities fall into the interior of the collection base 3. Then, the auger 303 rotates inside the collection base 3 and pushes the impurities toward the discharge port of the collection base 3 to clean the interior of the collection base 3, preventing excessive accumulation of impurities from affecting the subsequent discharge space of impurities.
[0030] Reference Figure 5-6 As shown, friction occurs when the inner wall of the filter cylinder 2 contacts the top of the scraper 301, generating a pulling force. The scraper 301 is easily displaced in the direction of rotation of the filter cylinder 2. The scraper 301 is detachably installed on the top of the collection seat 3 through the slots 3013 on both sides, which engage with the extension block 3014 from the end and then move in the direction of gear I 201. The slots 3013 on both sides of the scraper 301 are C-shaped and engage with the extension block 3014. Therefore, when the scraper 301 is displaced in the direction of rotation of the filter cylinder 2, the engagement of the slots 3013 with the extension block 3014 causes the extension block 3014 to move in the direction of displacement of the scraper 301. This ensures that there is always a connecting link between the engaging block 3011 and the scraper 301, which can prevent the scraper 301 from derailing from the engaging block 3011 on one side when it is displaced excessively, thus affecting its use.
