Description

Technical Field

[0001] The utility model relates to a vibrating hopper for discharging wet sludge, belonging to the technical field of sludge treatment equipment. Background Art

[0002] Currently, among various sludge disposal methods in China, most adopt the sludge centralized drying technology for disposal, and the wet sludge is transported to the sludge disposal enterprise by transport vehicles for centralized drying treatment. In the sludge disposal process, in order to centrally receive and store the wet sludge, a wet sludge storage bin needs to be set as a temporary storage facility. In order to prevent people from accidentally falling into the sludge bin and large objects from falling into the sludge bin, a grille needs to be set at the discharge port of the wet sludge bin as a safety protection measure to avoid people falling. However, due to the high viscosity of the wet sludge, it is easy to adhere to the grille. If the aperture is designed relatively small, the wet sludge is not easy to fall into the bin. Therefore, generally, the aperture of the grille is designed to be ≥200*200mm. However, in the actual production and operation process, due to the difficulty in controlling the sludge source, the sludge transported by the transport vehicle may be mixed with human-abandoned objects such as angle steel sections, square steel heads, iron wires, and stones. If these impurities are not removed before the wet sludge enters the bin, it may damage the subsequent sludge conveying equipment and drying disposal equipment, cause equipment failures, and even result in unnecessary shutdown for maintenance, increasing the maintenance cost. Summary of the Utility Model

[0003] The utility model aims at the defects of the prior art and provides a vibrating hopper for discharging wet sludge.

[0004] The technical solution for the utility model to solve the above technical problems is as follows:

[0005] A vibrating hopper for discharging wet sludge includes a hopper body. The two bottom sides of the hopper body are respectively connected with support plates through elastic components. The hopper body is installed on the upper part of the wet sludge storage bin through the support plates. Vibrators are symmetrically arranged on the side surface of the hopper body, and an impurity removal grille is arranged at the bottom of the hopper body.

[0006] The beneficial effect of the utility model is as follows: The utility model installs the hopper body on the upper part of the wet sludge storage bin through elastic components, and a vibrator is installed on the hopper body to provide a vibration power source for the hopper body. Under the action of the vibrator, the elastic components drive the hopper body to vibrate, driving the impurity removal grille to vibrate, so that the sludge on the impurity removal grille falls into the wet sludge storage bin through the gaps of the impurity removal grille, completing the sludge screening. The impurities are screened and isolated by the impurity removal grille, preventing the impurities from entering the wet sludge storage bin, and playing a role in protecting the safe operation of downstream equipment.

[0007] On the basis of the above technical solution, the utility model can also make the following improvements:

[0008] Furthermore, the elastic component includes a plurality of compression springs, and two ends of each compression spring are respectively connected to the support plate and the hopper body.

[0009] The beneficial effect of adopting the above further technical solution is that: under the action of the vibration force of the vibrator, the compression springs continuously undergo elastic deformation, thereby driving the hopper body to vibrate up and down.

[0010] Furthermore, spring support seats are provided on the support plate corresponding to the compression springs. The spring support seats are cylindrical groove pipes with open upper ends. The inner diameter of the spring support seats is larger than the diameter of the compression springs, and the ends of the compression springs are inserted into the spring support seats.

[0011] The beneficial effect of adopting the above further technical solution is that: by installing the compression springs through the spring support seats, the compression springs can be constrained and fixed, playing a role in preventing the compression springs from generating horizontal displacement due to vibration.

[0012] Furthermore, a mounting plate is provided on the hopper body. The mounting plate is horizontally arranged. Spring mounting posts are provided on the bottom of the mounting plate corresponding to the compression springs. The diameter of the spring mounting posts is smaller than the inner diameter of the compression springs, and the ends of the compression springs are sleeved on the spring mounting posts.

[0013] The beneficial effect of adopting the above further technical solution is that: by installing the compression springs on the hopper body through the spring mounting posts and inserting the spring mounting posts into the compression springs, the compression springs can be constrained and fixed, playing a role in preventing the compression springs from generating horizontal displacement due to vibration.

[0014] Furthermore, reinforcing rib plates are provided between the mounting plate and the hopper body.

[0015] The beneficial effect of adopting the above further technical solution is that: the reinforcing rib plates enhance the mounting strength of the mounting plate on the hopper body, ensuring the stability of the mounting plate.

[0016] Furthermore, a vibrator support is provided on the side of the hopper body, and the vibrator is installed at the bottom of the vibrator support.

[0017] The beneficial effect of adopting the above further technical solution is that: by installing the vibrator through the vibrator support, the installation of the vibrator is more stable.

[0018] Furthermore, the hopper body is U-shaped.

[0019] The beneficial effect of adopting the above further technical solution is that: the hopper body adopts a U-shaped structure, and the lower part of the side wall of the hopper body has an inclination angle, which is convenient for the wet sludge in the hopper body to slide downwards.

[0020] Furthermore, the hopper body includes a grille support frame and three side wall panels provided on the grille support frame, and the impurity removal grille is installed on the grille support frame.

[0021] The beneficial effects of adopting the above further technical solution are as follows: The impurity removal grille is installed through the grille support frame, which facilitates the installation and maintenance of the impurity removal grille; the hopper body forms a U-shaped hopper through the three side wall panels, preventing the sludge splashed when the transport vehicle unloads wet sludge from polluting the surrounding environment. The upper part of the hopper body is open, which is convenient for the vehicle to align the vehicle discharge port with the middle position of the impurity removal grille when reversing, making the dumping of wet sludge more convenient and accurate.

[0022] Furthermore, an L-shaped cofferdam support groove is provided on the grille support frame, and the impurity removal grille is installed in the cofferdam support groove.

[0023] The beneficial effects of adopting the above further technical solution are as follows: The impurity removal grille is installed through the cofferdam support groove, which plays a role in restraining the impurity removal grille and avoiding the horizontal displacement of the impurity removal grille caused by vibration.

[0024] Furthermore, the mesh size of the impurity removal grille is ≥40×(100 - 200) mm.

[0025] The beneficial effects of adopting the above further technical solution are as follows: With the above-mentioned mesh size of the impurity removal grille, the impurities in the wet sludge are not easily dropped into the wet sludge storage bin. Description of the Drawings
