Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sludge treatment, in particular to a quicklime feeding device for sludge reduction treatment. Background Technique
[0002] At present, quicklime is needed as an additive during sludge reduction treatment. Quicklime is generally stored in a silo, and there is a discharge port at the bottom of the silo. When feeding is required, the discharge port is opened, and the quicklime is discharged from the discharge port. However, since quicklime is in small granular or powdery form, problems such as bridging, clogging, and caking are likely to occur at the discharge port during feeding, resulting in discontinuous or even non-discharge of materials. Manually poking open the discharge port is quite time-consuming and laborious. Summary of the Invention
[0003] The purpose of the utility model is to provide a quicklime feeding device for sludge reduction treatment aiming at the defects existing in the prior art, which can realize continuous and stable feeding of quicklime.
[0004] The technical solution of the utility model is: a quicklime feeding device for sludge reduction treatment, including a bracket, a silo is installed on the bracket, and a horizontally arranged tubular screw conveyor is provided below the silo;
[0005] A group of hopper-shaped guide grooves communicating with the silo are provided at the bottom of the silo, and the bottom of each guide groove is communicated with the conveying pipe of the tubular screw conveyor;
[0006] A horizontally arranged frame is erected on the top of the silo, and a group of guide mechanisms corresponding to each guide groove one by one are provided on the frame;
[0007] The guide mechanism includes a vertically arranged motor, the rotating shaft of the motor is connected downward with a guide screw belt, and the guide screw belt extends into the inner bottom of the cavity of the guide groove.
[0008] Preferably, a group of vibrating mechanisms for knocking the outer wall of the silo corresponding to each guide groove one by one are provided outside the silo.
[0009] Preferably, the vibrating mechanism includes a swinging mechanism fixed on the outer wall of the silo, the rotating end of the swinging mechanism is connected with a spring, and the free end of the spring is connected with a vibrating hammer.
[0010] Preferably, a slot vertically penetrating the conveying pipe is provided at the outlet end of the conveying pipe of the tubular screw conveyor, a baffle is slidably connected in the slot, a horizontally arranged connecting plate is provided at the top of the baffle, and a lifting mechanism is provided between the connecting plate and the conveying pipe.
[0011] Preferably, the lifting mechanism is a cylinder, a hydraulic cylinder or an electric telescopic rod.
[0012] Compared with the prior art, the utility model has the following advantages:
[0013] When the utility model uses a tubular screw conveyor to unload materials in conjunction with a silo, quicklime in the silo is fed into the tubular screw conveyor through a plurality of guide troughs. Even if quicklime bridging, blockage, compaction, or other problems occur in one of the guide troughs, the materials can still be unloaded continuously and stably by using the other guide troughs.
[0014] By actively starting or timing the motor to drive the guide screw to rotate, the quicklime inside the guide trough can be broken up, thereby solving the problems of quicklime bridging, blockage, and compaction when discharging materials. Compared with manually poking open a blocked discharge port, it saves time and effort and is more efficient.
[0015] The swing mechanism drives the spring to swing back and forth, and the spring drives the vibrating hammer to strike the outer wall of the silo to achieve the vibration effect, which can effectively avoid the problem of quicklime sticking to the inner wall of the silo when unloading.
[0016] The lifting mechanism can drive the baffle to rise and fall through the connecting plate, so as to open and close the outlet end of the conveying pipe. After the tubular screw conveyor finishes unloading, the baffle is lowered to close the outlet end of the conveying pipe, which can effectively prevent quicklime from spilling out from the outlet end of the conveying pipe under the action of gravity.

DETAILED DESCRIPTION
[0021] The utility model is further described below with reference to the accompanying drawings and embodiments. Example 1
[0022] like Figures 1 to 3, A quicklime feeding device for sludge reduction treatment, comprising a bracket 5, a silo 1 is installed on the bracket 5, and a horizontally arranged tubular screw conveyor 4 is provided below the silo 1.
[0023] A group of hopper-shaped guide troughs 6 communicating with the silo 1 are provided at the bottom of the silo 1, and the bottom of each guide trough 6 is communicated with the conveying pipe 7 of the tubular screw conveyor 4.
[0024] A horizontally arranged frame 3 is fixedly installed on the top of the silo 1, and a group of feeding mechanisms 2 corresponding to each guide trough 6 one by one are provided on the frame 3.
[0025] The feeding mechanism 2 includes a vertically arranged motor 15, the rotating shaft of the motor 15 is connected downward with a feeding spiral ribbon 16, and the feeding spiral ribbon 16 extends into the inner bottom of the guide trough 6.
[0026] During use, quicklime is stored in the silo 1. When starting the tubular screw conveyor 4 to discharge materials, the quicklime in the silo 1 is respectively fed into the tubular screw conveyor 4 by a plurality of guide troughs 6. Even if a certain guide trough 6 has problems such as quicklime bridging, blocking, caking, etc., continuous and stable feeding can still be achieved by using other guide troughs 6 for feeding;
[0027] By actively turning on or regularly turning on the motor 15 to drive the feeding spiral ribbon 16 to rotate, the quicklime inside the guide trough 6 can be dispersed, thus solving problems such as quicklime bridging, blocking, caking, etc. that occur during feeding. Embodiment 2
[0028] This embodiment is further optimized on the basis of the above embodiment. Specifically:
[0029] As Figure 1 And Figure 2 , A group of vibration mechanisms 11 for knocking on the outer wall of the silo 1 corresponding to each guide trough 6 one by one are provided on the outer side of the silo 1.
[0030] The vibration mechanism 11 includes a swing mechanism 12 fixed on the outer wall of the silo 1, a spring 13 is connected to the rotating end of the swing mechanism 12, a vibration hammer 14 is connected to the free end of the spring 13, and the swing mechanism 12 can be selected from a swing cylinder or a swing motor 15.
[0031] By driving the spring 13 to swing reciprocally through the swing mechanism 12, and then driving the vibration hammer 14 to knock on the outer wall of the silo 1 to achieve the vibration effect, it can effectively avoid the problem of quicklime caking and hanging on the inner wall of the silo 1 during feeding. Embodiment 3
[0032] This embodiment is further optimized on the basis of the above embodiment. Specifically:

After the feeding of the tubular screw conveyor 4 is completed, lowering the baffle 8 to close the outlet end of the conveying pipe 7 can effectively avoid the problem of quicklime spilling out from the outlet end of the conveying pipe 7 under the action of gravity.
[0035] The present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can also be made without departing from the purpose of the present utility model, and the changed content still belongs to the protection scope of the present utility model.
