Description

TECHNICAL FIELD

[0001] The utility model relates to wastewater filtering equipment, especially wastewater filtering equipment based on solar energy. BACKGROUND

[0002] In the wastewater treatment process in the industrial field, the filtration link is very important. There is a multi-core wastewater treatment device in the wastewater filtering equipment, which usually adopts a vertical structure, and a plurality of fine filter cartridges are vertically and parallelly arranged inside. The original intention of this device design is to enhance the fine filtration treatment capacity. In theory, the parallel configuration of multiple cartridges can increase the flow treatment capacity to more than 3 times of the single cartridge device. The specific benefit depends on the specific number of fine filter cartridges.

[0003] However, in the actual manufacturing process, the cost of fine filter cartridges is very high. The commonly seen ultrafiltration membrane cartridge on the market is generally around 3000 yuan. The investment cost of the multi-core fine filtration system is also very high, which is almost proportional to the increase of fine filtration treatment capacity, making it difficult to estimate the economic cost in the investment stage. In addition, the operation and maintenance cost also increases significantly. Since the unit treatment capacity of each cartridge in the multi-core fine filtration system decreases compared with the single cartridge, the frequency of multi-core fine filtration cleaning, backwashing and cartridge replacement increases, and the overall application cost is more expensive.

[0004] In addition to the cost defect, the vertical structure flushes the backwashing water upward when the fine filter cartridge is backwashed. In actual use, we found that it is difficult to flush the upper part of the fine filter cartridge to the right position, which affects the filtration capacity of the cartridge and is one of the reasons for the accelerated replacement frequency of the cartridge. At the same time, the power-on time of the water pump also increases accordingly, and the power waste is more serious.

[0005] If the content of large particles (such as sand, fiber, plastic fragments) in wastewater is extremely high, the coarse filter cartridge is more likely to be blocked than the fine filter cartridge, and there is no research and production on the market. UTILITY MODEL CONTENTS

[0033] The utility model will be described in further detail below in combination with the drawings and specific embodiments.

[0034] As Figures 1-7 It is shown that the wastewater filtering device based on solar energy disclosed by the embodiment is essentially a horizontal filtering structure in filtering form. Considering the outdoor use, the embodiment combines solar energy on the basis of the innovative wastewater filtering device to solve the problem of power waste and make long-term operation more economical.

[0035] As Figure 2 It is shown that the wastewater filtering device based on solar energy disclosed by the embodiment is essentially a horizontal filtering structure in filtering form. Considering the outdoor use, the embodiment combines solar energy on the basis of the innovative wastewater filtering device to solve the problem of power waste and make long-term operation more economical. Figures 1-2 It is shown that the wastewater filtering device based on solar energy disclosed by the embodiment is essentially a horizontal filtering structure in filtering form. Considering the outdoor use, the embodiment combines solar energy on the basis of the innovative wastewater filtering device to solve the problem of power waste and make long-term operation more economical.

[0036] In the embodiment, the filter cylinder 20 is divided into a coarse filter assembly 40 and a fine filter core 50, the filter cylinder 20 is provided with a water inlet 23 and a water outlet 24, and the water inlet 23 and the water outlet 24 are both provided with flanges and connected to external pipelines through the flanges.

[0037] As Figure 5As shown, the coarse filter assembly 40 preferably comprises several coarse filter cartridges 41 in parallel and in communication with the chamber of the fine filter cartridge 50, that is, the embodiment changes the design of the traditional coarse filter part single cartridge to the parallel mode of multiple cartridges, and the specific standardized multi-cartridge modular design in production will not be more expensive than the customized large single cartridge filter in cost, and the coarse filter cartridges 41 arranged in parallel can better cope with large particles in wastewater, such as sand, fiber, plastic fragments, and when a single coarse filter cartridge 41 is blocked, it will not affect the filtering effect of other coarse filter cartridges 41, and the ability to cope with blockage is stronger. On this basis, in order to solve the pressure difference and cleaning problem caused by the blockage of a single coarse filter cartridge 41, each coarse filter cartridge 41 is equipped with a backwashing unit in dynamic contact with it, and the backwashing unit includes a push cylinder 45 indirectly connected to a solar photovoltaic panel 60 through an energy storage device. It can be understood that each coarse filter cartridge 41 is equipped with a corresponding push cylinder 45 of the backwashing unit, so that the backwashing unit can operate independently and more specifically during backwashing. In addition, the solar photovoltaic panel 60 converts light energy into electrical energy and stores it in an external energy storage device (not shown in the embodiment), which in turn powers the push cylinder 45, making long-term operation more economical.

[0038] As shown, Figure 6 The fine filter cartridge 50 comprises several layers of rubber activated carbon composite layers 51, which are elastic and have adsorption and filtration functions, impact resistance, and in the embodiment, the rubber activated carbon composite layer 51 has strong elastic deformation ability, which is convenient for operators to maintain and replace.

[0039] In the embodiment, the coarse filter assembly 40 and the fine filter cartridge 50 of the filter cylinder 20 are separated by a partition plate 42 to form independent chambers, and the two independent chambers are communicated through the coarse filter cartridge 41 as mentioned above, that is, the wastewater filtered by the coarse filter cartridge 41 flows into the chamber where the fine filter cartridge 50 is located; as Figures 1-3 As shown, the water inlet 23 is connected to the side of the chamber where the coarse filter assembly 40 of the filter cylinder 20 is located in the form of water inlet, preventing wastewater without coarse filtration from flowing into the chamber where the fine filter cartridge 50 is located. The water outlet 24 is connected to the side of the chamber where the fine filter cartridge 50 of the filter cylinder 20 is located, specifically at the end position of the filter cylinder 20.

[0040] Preferably, the end of the chamber of the filter cartridge 20 coarse filter assembly 40 is sealingly connected with the rear end cover 21, the filter cartridge 20 corresponds to the position of the rear end cover 21 to form a circle of abutting table, and then the two are connected by the countersunk head bolt, and the outer circle of the rear end cover 21 is provided with a sealing strip to enhance the sealing performance of the two. Because of the above setting form is existing, therefore the drawing is not shown; on this basis, the rear end cover 21 is connected with a plurality of push cylinders 45 in a penetrating manner, that is, the front end of the push cylinder 45 is connected to the inside and outside of the rear end cover 21, and the connection position inside is sealed by a sealing strip. The push cylinder 45 and the outside of the rear end cover 21 are connected again through a connecting plate, that is, the push cylinder 45 is surrounded by a connecting plate abutting on the outside of the rear end cover 21, and is fastened by a countersunk head bolt to enhance the connection between the push cylinder 45 and the rear end cover 21.

[0041] Correspondingly, one end of the plurality of coarse filter elements 41 is connected to the partition plate 42, and the backwashing unit further comprises a moving cylinder 43 driven by the push cylinder 45. The moving cylinder 43 is open at one end and is provided with a moving scraping end 44 whose inner wall is in contact with the outer wall of the coarse filter element 41. The moving cylinder 43 is implemented in a reciprocating displacement manner along the length extension direction of the coarse filter element 41 under the drive of the push cylinder 45. It can be understood that the moving cylinder 43 is in the form of a sleeve of the coarse filter element 41. By providing the moving scraping end 44 at the front end of the moving cylinder 43 and abutting the moving scraping end 44 with the coarse filter element 41, the clogged impurities outside the coarse filter element 41 are scraped. It should be noted that the piston rod of the push cylinder 45 is connected to the other end of the moving cylinder 43. In the initial state, the piston rod is retracted, and the position relationship between the moving cylinder 43 and the coarse filter element 41 is as shown in Figure 5 In addition, the material of the moving scraping end 44 abutting with the coarse filter element 41 is rubber material, which not only ensures the scraping effect, but also prevents damage to the coarse filter element 41;

[0042] On this basis, when the coarse filter assembly 40 needs to be backwashed, the moving cylinder 43 is first driven by the push cylinder 45 to move to the side of the connection end of the coarse filter element 41 and the partition plate 42. During the movement, the moving scraping end 44 continuously scrapes the clogged impurities outside the coarse filter element 41. After the operation is completed, the push cylinder 45 and the moving cylinder 43 are reset, and the backwashing medium process begins. The entire backwashing process of the present embodiment is better than the traditional vertical structure in terms of clearing the blockage.

[0043] Regarding the backwashing setting, as Figures 1-3As shown, the filter cartridge 20 is connected with a backwash inlet pipe 31 communicating with the chamber where the coarse filter assembly 40 is located, the backwash inlet pipe 31 is of the upper inlet type, a branch pipe 32 is arranged at the lower corresponding position of the backwash inlet pipe 31 to communicate with the filter cartridge 20 and the backwash cartridge 30, a blowdown valve 33 is communicated with the other end of the backwash cartridge 30, and the scraped impurities are discharged under the action of gravity and pressure under the action of backwashing medium.

[0044] Preferably, the end of the fine filter core 50 chamber of the filter cartridge 20 is sealingly connected with a front end connector 22 forming an opening, such as Figure 4 As shown, the outer peripheral wall of the front end connector 22 is provided with a plug hole 221 matched with the plug 26, and the front end connector 22 is connected with a quick release flange 25 detachably connected through the plug 26, the quick release flange 25 is existing, the above design facilitates the operator to disassemble the quick release flange 25, and the purpose of disassembly is to facilitate the operator to replace the fine filter core 50, which is also the reason why the rubber active carbon composite layer 51 is preferably provided with elastic deformation ability.

[0045] The solar photovoltaic panel 60 is fastened on the support leg 10 through a photovoltaic panel connecting frame 61, and the solar photovoltaic panel 60 and the photovoltaic panel connecting frame 61 are movably connected through a slide rod 62 to adjust the inclination angle of the solar photovoltaic panel 60, and it should be noted that when the solar photovoltaic panel 60 is adjusted to the adapted inclination angle, it can be locked through the bolt-nut cooperation at the mutual connection of the slide rod 62, and the setting form and connection mode are not unique to the present application.

[0046] The present application discloses a wastewater filtering equipment based on solar energy, which changes the traditional vertical structure and designs a horizontal layout, and the large-particle content in wastewater is high, the large single-core filter is replaced by a standardized multi-core modular design in the coarse filter part, which not only improves the flow capacity, but also enhances the anti-blocking performance, and under the condition of unchanged cost, the backwashing effect and efficiency are significantly improved through physical scraping and medium flushing, which is beneficial to long-term economic benefits, and the physical scraping function of the coarse filter part is powered by solar energy, which is environmentally friendly and reduces operating costs.
