Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a pretreatment device for sewage capacity expansion and deep treatment. Background Art

[0002] Sewage expansion and deep treatment is a comprehensive process aimed at increasing the treatment capacity of sewage treatment plants while ensuring that the effluent quality meets higher standards to meet the requirements of reuse or discharge. This process usually includes the expansion and upgrading of existing sewage treatment facilities and the use of advanced deep treatment technologies.

[0003] In the process of sewage expansion and deep treatment, pretreatment equipment plays a vital role. They are mainly used to remove large particles, suspended matter, grease and other impurities in sewage, providing favorable conditions for subsequent treatment. The screen is one of the most commonly used pretreatment equipment in sewage treatment. It can intercept and remove larger floating and suspended matter in sewage, such as branches, plastic bags, fibers, etc., to prevent these debris from clogging subsequent treatment equipment.

[0004] However, the existing grilles have the following problems: after the grilles block larger debris, it is inconvenient for humans to clean the debris blocked on one side of the grille. After a long time, the debris tends to accumulate, hindering the flow of sewage and thus reducing the sewage treatment efficiency. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings in the prior art that after the grille blocks larger debris, it is inconvenient for humans to clean the debris blocked on one side of the grille. After a long time, the debris is likely to accumulate, causing obstruction to the flow of sewage, thereby reducing the treatment efficiency of sewage. A pretreatment device for sewage expansion and deep treatment is proposed.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0008] A lifting mechanism is provided on the front side of the grille for removing debris from the sewage;

[0009] The pushing mechanism is arranged on the front plate and is used to push the sundries.

[0010] In a possible design, the lifting mechanism includes two electric telescopic rods, two side panels, a perforated plate and two No. 1 sliders, the rear sides of the two side panels are respectively fixedly connected to the front sides of the two No. 1 sliders, the two No. 1 sliders are respectively slidably connected to the two No. 1 slides, the bottoms of the two side panels are respectively fixedly connected to the top sides of the same perforated plate, the perforated plate is located on the front side of the grille, the fixed ends of the two electric telescopic rods are respectively fixedly connected to the bottoms of the two connecting blocks, the telescopic ends of the two electric telescopic rods are respectively fixedly connected to the tops of the two side panels, and the two electric telescopic rods are electrically connected to the controller through connecting lines.

[0011] In one possible design, the pushing mechanism includes a pushing plate, a shielding cover, a motor, a screw rod, two sliding blocks, two No. 2 slides, a vertical plate and a connecting rod. The shielding cover is fixed at the top center of the grille by bolts, the bottom of the motor is fixedly connected to the No. 1 plate by bolts, and the No. 1 plate is fixedly connected to the top of the grille by bolts. The output shaft of the motor rotates through the front inner wall of the shielding cover and is fixedly connected to one end of the screw rod. One end of the screw rod is rotatably connected to the front side of the shielding cover, and the other end of the screw rod is rotatably connected to the rear side of the vertical plate. The bottom of the vertical plate is fixed to the top of the front plate The fixing connection is that the connecting rod is threadedly sleeved on the screw rod, and the bottom end of the connecting rod slides through the movable hole and is fixedly connected to the top center of the push plate. The two sides of the push plate are respectively slidably connected to the side close to the two side plates, and the two sides of the sliding blocks are respectively fixedly connected to the two sides of the same connecting rod. The bottoms of the two sliding blocks are fixedly connected with a No. 2 slider adapted for the No. 2 slide groove, and the two No. 2 slide grooves are respectively arranged on both sides of the top of the same front plate, and the two No. 2 sliders are respectively slidably connected to the two No. 2 slide grooves, and the shielding cover is arranged above the motor and the controller.

[0012] In a possible design, mounting plates are fixedly connected to both sides of the rear side of the grille for facilitating installation and fixation of the grille, and a plurality of mounting holes are provided on the two mounting plates for facilitating installation.

[0013] In a possible design, both sides of the bottom of the grille are fixedly connected with plug posts for stabilizing the grille, and the bottoms of the two plug posts are fixedly connected with cone nails for easy insertion into a plane.

[0014] In a possible design, the two No. 1 sliding blocks and the two No. 1 sliding grooves are both configured to be in a T-shape to prevent the side panel from separating from the grille.

[0015] In this application, when the equipment is put into use, the sewage is first preliminarily filtered through the grille to intercept larger floating objects and suspended matter. The orifice plate is located under the sewage. The electric telescopic rod is used to move the side plate and the orifice plate fixedly connected thereto upward. During the rising process of the orifice plate, the holes on it allow water to flow through, while the debris is retained on the orifice plate. Under the control of the controller, the electric telescopic rod drives the orifice plate to rise and pick up the debris from the sewage. After the orifice plate rises, the orifice plate and the debris leave the sewage and are located above the sewage. The staff will collect them by hand. The net is placed below the front side of the orifice plate, and then the motor starts working, and its output shaft drives the screw to rotate. Since the connecting rod is threaded on the screw, the rotation of the screw will be converted into horizontal movement of the connecting rod. The bottom end of the connecting rod is fixedly connected to the push plate, so the push plate also moves horizontally. At the same time, the sliding block and the No. 2 slider in the No. 2 slide groove ensure the stability of the push plate during movement. When the push plate moves to the front side of the orifice plate, it pushes the debris on the orifice plate into the collection net set at the bottom of the front side of the orifice plate, thereby completing the collection and processing of the debris.

[0016] The beneficial effects of the utility model are:

[0017] In the utility model, the orifice plate picks out the debris from the sewage through the lifting mechanism and the pushing mechanism, which reduces the difficulty for the staff to pick up the debris from the sewage and improves the efficiency of picking up the debris. When the pushing plate and the collecting net are raised, the debris is collected, and the automatic collection and cleaning of the debris is realized, which greatly improves the processing efficiency and reduces the workload of the staff. The plug-in column fixed at the bottom of the grille and the cone nail design at the bottom enhance the stability of the grille, prevent it from shifting or tipping over during use, and ensure the long-term stable operation of the equipment. At the same time, the mounting plate provided on the grille facilitates the installation of the grille, thereby reducing the difficulty of using the grille. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Example

[0024] Reference Figure 1-Figure 4 A pretreatment device includes a grille 1. The grille 1 is placed in the sewage pretreatment area. The grille 1 is firmly installed in a predetermined position using bolts or other fasteners through the mounting holes 3 on the mounting plates 2 fixedly connected on both sides of the rear side. During installation, ensure that the grille 1 is level and stable so that subsequent operations can proceed smoothly.

[0025] The bottoms of the two side panels 6 are fixedly connected to the top sides of the orifice plates 7 to form a liftable frame. This frame will be used to carry and lift debris in the sewage. The fixed ends of the two electric telescopic rods 11 are respectively installed on the connecting blocks 12 on the top of the front side of the grille 1, and the telescopic ends are fixedly connected to the tops of the two side panels 6. Through the control of the controller 18, the uneven extension and contraction of the electric telescopic rods can be prevented. The electric telescopic rods can drive the side panels 6 and the orifice plates 7 to move up and down to achieve the lifting and lowering operation of debris in the sewage, ensuring that the two No. 1 sliders 9 slide into the No. 1 chute 8 on both sides of the front side of the grille 1 respectively, so that the side panels 6 can remain stable during the lifting process to prevent shaking or deviation. When a certain amount of debris accumulates on the orifice plates 7, the electric telescopic rods 11 lift the orifice plates 7 on the front side of the grille 1, and the electric telescopic rods 11 are activated by the controller 18, so that the side panels 6 drive the orifice plates 7 to rise and pick up the debris from the sewage. The holes on the orifice plates 7 allow water to flow through and intercept the debris.

[0026] Fix the shielding cover 5 to the top center of the grille 1 by bolts, ensuring that it can completely cover the motor 16 and the controller 18 to play a waterproof and protective role, and then open a heat dissipation hole on its rear side to facilitate the heat dissipation of the motor 16. Install the motor 16 on the top of the grille 1 and fix it by bolts. The output shaft of the motor 16 passes through the shielding cover 5 and is fixedly connected to one end of the screw rod 15. The other end of the screw rod 15 is rotatably connected to the vertical plate 14, and the vertical plate 14 is fixed to the top of the front plate 19. The connecting rod 10 is threadedly sleeved on the screw rod 15. At the same time, two sliding blocks 17 are fixed on both sides of the connecting rod 10, and the No. 2 slider at the bottom of the sliding block 17 is slidably connected to the No. 2 slide groove 20 at the top of the front plate 19 to ensure that the pushing plate 13 is stable and does not shake when it moves horizontally. In this way, after the debris is lifted up through the orifice plate 7, the staff can set a collection net at the bottom of the front side of the orifice plate, and push the debris from the orifice plate 7 into the net through the push of the push plate 13, so as to facilitate the collection and treatment of debris in the sewage.

[0027] This application can be used in the field of sewage treatment, and can also be used in other fields applicable to this application. Example

[0028] refer to Figure 1-Figure 4 , based on the improvement of the first embodiment, a pretreatment device for sewage expansion and deep treatment, comprising:

[0029] In order to further enhance the stability of the grille 1, the posts 4 fixed on both sides of the bottom of the grille 1 are inserted into the ground or prefabricated slots. The conical nail design at the bottom of the posts 4 helps to insert them into the plane to prevent the grille from shifting during use.

[0030] However, as is well known to those skilled in the art, the working principles and wiring methods of the controller 18, the electric telescopic rod 11 and the motor 16 are commonplace, and are all conventional means or common knowledge, and will not be elaborated here. Those skilled in the art can make any optional selections according to their needs or convenience. The electric telescopic rod 11 and the motor 16 are both connected to the controller 18 through lines and are powered by an external power supply.

[0031] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
