Description

Technical Field

[0001] This utility model relates to the field of chemical production equipment technology, and in particular to a quantitative filling device for flocculant production. Background Technology

[0002] In chemical production, especially in the manufacturing of fine chemicals such as flocculants, the final filling and packaging process directly affects the market value and effectiveness of the product. To ensure that the quality of each unit of product is consistent and meets the specifications, precise quantitative filling is one of the indispensable core technologies on the production line.

[0003] Currently, liquid quantitative filling equipment on the market often uses the time-pressure method or flow meters to control the filling volume. These methods can achieve good results for homogeneous fluids with stable physical properties. However, for materials such as flocculants, the physical properties are more special. They are suspensions containing incompletely dissolved particles, or their viscosity can change with factors such as temperature and batch. When the viscosity or flowability of the material fluctuates, the actual volume of material flowing out will vary significantly even within the same opening time when using the time-pressure method, resulting in a significant decrease in filling accuracy. Similarly, using flow meters for measurement is also easily affected by impurities, air bubbles, and viscosity changes in the material, which will not only reduce the measurement accuracy but may also cause the flow meter to become clogged or damaged, affecting the continuity and stability of production.

[0004] Therefore, this utility model proposes a quantitative filling device for flocculant production to overcome the shortcomings of the prior art. Utility Model Content

[0005] In view of the problems of low metering accuracy and poor filling consistency in existing quantitative filling equipment for flocculant production when processing materials with unstable viscosity or containing suspended particles, this utility model aims to provide a quantitative filling equipment for flocculant production with an improved structure that can effectively solve the above problems.

[0006] This utility model provides a quantitative filling device for flocculant production, including: a fixed frame and a quantitative mechanism installed on the fixed frame. The quantitative mechanism includes a storage tank, the bottom of which is connected to a branch pipe. A valve, a metering pump, a conveying component, an output pipe, and a gate are installed in series on the branch pipe.

[0007] Among them, the conveying component is the core innovative structure for achieving high-precision volumetric metering, including a metering tank with a specific volume, a sealing push rod that is slidably set inside the metering tank, and a hydraulic push rod for driving the reciprocating motion of the sealing push rod.

[0008] Furthermore, the aforementioned components are combined in the following manner: the branch pipe is connected to the inlet of the metering pump after the valve, the outlet of the metering pump is connected to the feed inlet of the metering tank, forming a passage for pre-transporting materials from the storage tank to the metering tank; the body of the hydraulic push rod is fixedly connected to the fixed frame, and the end of the piston rod is fixedly connected to the sealing push rod to form a driving relationship; the bottom of the metering tank is connected to the output pipe, and the gate is installed in series on the output pipe, forming an output passage for precise discharge and safe control.

[0009] Preferably, in order to ensure the uniformity of the material before filling, a motor is fixedly installed on the side wall of the storage tank, the output shaft of the motor passes through the wall of the storage tank and extends into its interior, and a stirring blade is fixedly connected to the end of the output shaft.

[0010] Preferably, in order to facilitate the addition of various auxiliary production materials, the quantitative filling equipment for flocculant production further includes a feeding mechanism, which is fixedly connected to the top of the storage tank.

[0011] More preferably, the feeding mechanism includes a fixed plate covering the top opening of the storage tank and a turntable rotatably disposed on the top surface of the fixed plate via a bearing. Multiple funnels are evenly distributed on the turntable along its circumference. A guide tube with its upper end facing the turntable is also disposed through the fixed plate. By rotating the turntable, different funnels can be aligned with the guide tube.

[0012] In a further preferred embodiment, in order to achieve precise locking of the rotation position of the turntable, a positioning plate for limiting the rotation of the turntable is also fixedly provided on the top surface of the fixed plate. In order to close the channel when no material is being fed, a sealing cover for opening and closing the channel can also be rotatably installed on the outer peripheral wall of the guide tube.

[0013] Preferably, in order to accommodate filling containers of different sizes, the bottom of the fixing frame is adjustablely connected to a support frame, which is located directly below the output pipe. The height of the support frame can be adjusted by a threaded lifting mechanism or a multi-stage locking structure to support containers of different heights.

[0014] This utility model has the following beneficial effects: 1. This utility model solves the problems of inaccurate filling volume and poor batch consistency caused by insufficient accuracy of a single metering method or unstable material flow in the prior art by setting up a dual metering mechanism in which a metering pump performs initial delivery and a hydraulic push rod drives a sealing push rod to perform piston-type volumetric metering in the metering tank. It achieves accurate metering, good repeatability and high degree of automation.

[0015] 2. This utility model solves the problems of cumbersome operation and inconvenient replacement when adding multiple different auxiliary agents in the prior art by setting a feeding mechanism with a rotatable turntable and funnels of various specifications. It optimizes the convenience of operation, improves production flexibility, and can quickly adapt to the needs of multiple production formulas.

[0016] 3. This utility model solves the problem that suspended or multi-component materials such as flocculants are prone to stratification or sedimentation during the standing and filling process by setting up a stirring blade driven by a motor in the storage tank for continuous stirring, which leads to uneven product quality. It ensures that the materials are always in a uniform mixing state during filling, thereby ensuring the consistency of the final product quality. Attached Figure Description

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them.

[0020] Example: Please refer to Figures 1 to 4This utility model provides a quantitative filling device for flocculant production, which aims to solve the problems of low filling accuracy and consistency of flocculants, inconvenient addition of auxiliary agents, and insufficient safety redundancy in the prior art.

[0021] like Figure 1 and Figure 2 As shown, the quantitative filling equipment for flocculant production includes a fixed frame 1 and a quantitative mechanism 2 installed on the fixed frame 1. The fixed frame 1 provides a stable mounting platform for all components of the equipment. The quantitative mechanism 2 is used to realize the storage and high-precision quantitative delivery of flocculant. Specifically, the quantitative mechanism 2 includes a storage tank 201, the bottom of which is connected to a branch pipe 204. A valve 205 is installed in series on the branch pipe 204 to control the opening and closing of the material flowing out of the storage tank 201. After passing through the valve 205, the branch pipe 204 is connected to the inlet of a metering pump 206. The metering pump 206 is used for preliminary flow control and delivery of the material. The quantitative mechanism 2 also includes a conveying assembly 207. The outlet of the metering pump 206 is connected to the inlet of the metering tank 2073 of the conveying assembly 207. The conveying assembly 207 consists of the metering tank 2073 and a sealing push rod 207. The device consists of a metering tank 2073 and a hydraulic push rod 2071. The metering tank 2073 is a cavity with a specific volume. One end of the sealing push rod 2072 is slidably disposed inside the metering tank 2073 and forms a dynamic seal with the inner wall of the metering tank 2073. The body of the hydraulic push rod 2071 is fixedly connected to the fixing frame 1, and the end of the piston rod is fixedly connected to the other end of the sealing push rod 2072. The hydraulic push rod 2071 drives the sealing push rod 2072 to make reciprocating linear motion inside the metering tank 2073, thereby realizing the precise discharge of a quantitative amount of material from the metering tank 2073. The bottom of the metering tank 2073 is connected to an output pipe 2075, which is used to guide the discharged material to the filling container. A gate 2074 is also connected in series on the output pipe 2075. The gate 2074 is a manual safety device used to quickly cut off the material output channel in an emergency.

[0022] Please refer to Figure 2 and Figure 3The feeding mechanism 3 is fixedly connected to the top of the storage box 201 and includes a fixed plate 301, a turntable 304, a bearing 303, a positioning plate 302, and multiple funnels 305. The fixed plate 301 covers the top opening of the storage box 201 and is fixedly connected to the storage box 201. The bearing 303 is installed at the center of the fixed plate 301. The turntable 304 is rotatably mounted on the top surface of the fixed plate 301 via the bearing 303. This rotatable connection via the bearing 303 reduces frictional loss when the turntable 304 rotates. Multiple funnels 305 are evenly distributed along the circumference of the turntable 304. The top surface of the fixed plate 301 is also fixedly equipped with... A positioning plate 302 is provided for rotating and limiting the turntable 304. The conduit 306 passes through the fixed plate 301, with its upper port facing the turntable 304 and its lower port extending into the storage box 201. In use, by rotating the turntable 304, funnels 305 of different diameters can be selected and moved to the top of the conduit 306. The positioning plate 302 precisely positions the funnels 305 so that their lower ports are aligned with the upper ports of the conduit 306, thus facilitating the addition of different additives. To prevent misoperation, a sealing cap 307 can be rotatably installed on the outer peripheral wall of the conduit 306 to close the channel of the conduit 306 when no material is being added.

[0023] As a preferred embodiment, to ensure the uniformity of the flocculant material by thorough mixing before quantitative filling, please refer to... Figure 2 A motor 202 is fixedly installed on the side wall of the storage tank 201. The output shaft of the motor 202 passes through the wall of the storage tank 201 and extends into its interior. A stirring blade 203 is fixedly connected to the end of the output shaft. The stirring blade 203 is driven by the motor 202 to rotate inside the storage tank 201, so that the material can be continuously stirred.

[0024] As another preferred embodiment, to facilitate adaptation to filling containers of different heights, please refer to... Figure 1 and Figure 4 A support frame 4 is adjustablely connected to the bottom of the fixed frame 1. The support frame 4 is located directly below the output pipe 2075 and is used to support the container to be filled. The connection between the support frame 4 and the fixed frame 1 can adopt a threaded lifting mechanism or a multi-stage locking structure to achieve flexible adjustment of its height to meet the filling needs of different packaging sizes.

[0025] Working principle: First, the flocculant raw material is added to the storage tank 201. The motor 202 is started, and the motor 202 drives the stirring blade 203 to rotate and continuously stir and mix the raw material to ensure the uniformity of the material. When filling is required, the valve 205 on the branch pipe 204 is opened. The material flows through the metering pump 206 under the action of gravity. The metering pump 206 pumps the material stably into the metering tank 2073 of the conveying assembly 207 at a set flow rate until the metering tank 2073 is full. Then, the hydraulic push rod 2071... Upon startup, the piston rod extends, pushing the sealing push rod 2072 to slide smoothly in the metering tank 2073 toward the output pipe 2075. The sealing push rod 2072 discharges the material of a precise volume from the metering tank 2073 through the output pipe 2075. During this process, the position of the support frame 4 can be adjusted in advance according to the height of the container to be filled, so that the container is stably supported under the output pipe 2075. In case of emergency or equipment failure, the gate 2074 can be manually closed to instantly cut off the material output channel and ensure production safety. When an auxiliary agent needs to be added, the turntable 304 of the rotating feeding mechanism 3 is rotated to align the funnel 305 of the required size with the guide tube 306 below, and is fixed by the positioning plate 302. The sealing cover 307 on the guide tube 306 is opened, and the auxiliary agent is put into the storage tank 201 through the funnel 305 and the guide tube 306. It is stirred and mixed with the main material. After completing one quantitative discharge, the piston rod of the hydraulic push rod 2071 retracts, driving the sealing push rod 2072 to reset. The metering pump 206 replenishes the material into the metering tank 2073 again to prepare for the next quantitative filling. This cycle is repeated to achieve continuous, automatic and high-precision quantitative filling operation.
