Description

Technical Field

[0001] This utility model belongs to the technical field of feeding devices, specifically relating to a feeding station for high-viscosity liquid auxiliary materials. Background Technology

[0002] In the pharmaceutical, chemical, and adhesive industries, high-viscosity materials such as colloids are continuously added during the mixing process when preparing slurries. Currently, these materials are mostly added through the nozzle of the mixer's upper tank. However, due to their high viscosity, these materials tend to adhere firmly to the mixing blades and tank walls when added through the nozzle, resulting in incomplete mixing, affecting the formulation ratio, and consequently impacting product quality. Furthermore, the adhesion of the colloids to the mixing blades and tank walls increases cleaning difficulty. Therefore, there is an urgent need to develop a feeding station for high-viscosity liquid additives that facilitates material addition, effectively prevents the added additives from adhering to the mixing blades and tank walls, is easy to clean, and effectively improves slurry quality. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of existing technologies where, when auxiliary materials are added through the inlet of the mixer's upper tank, they tend to adhere to the mixing blade and the tank wall, resulting in incomplete mixing, affecting the formula ratio, and causing poor slurry mixing quality. This invention provides a feeding station for high-viscosity liquid auxiliary materials that facilitates material addition, effectively prevents the added auxiliary materials from adhering to the mixing blade and the tank wall, is easy to clean, and effectively improves slurry quality.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a feeding station for high-viscosity liquid auxiliary materials, comprising: a holding tank, a lid covering the holding tank, and a pneumatic pressing assembly installed on the lid. The lid is connected to the holding tank via a rotary locking assembly. The bottom end of the holding tank has a discharge port, and the bottom end of the mixing tank has a feed port. The discharge port of the holding tank is connected to the feed port of the mixing tank via a pipe. A gate valve assembly is also installed at the feed port of the mixing tank. Opening the gate valve assembly... The auxiliary material in the holding bucket is pumped into the mixing bucket by a pneumatic pressing assembly. After the feeding is completed, the auxiliary material located at the feed inlet of the mixing bucket is squeezed into the mixing bucket by a gate valve assembly. The pneumatic pressing assembly includes a cylinder that is vertically sealed and fixed on the bucket cover, an end cap that is sealed and fixed at the top of the cylinder, and a pressing piston rod installed in the cylinder. A pressing piston head is sleeved on one end of the pressing piston rod, and a pressing plate is installed at the other end through the end cap. The pressing piston head is slidably connected to the inner wall of the cylinder.

[0005] Furthermore, a two-way pipe is fixed at the feed inlet of the mixing tank. One port of the two-way pipe is connected to the discharge outlet pipe of the material container, and a gate valve assembly is installed at the other port.

[0006] Furthermore, the gate valve assembly includes a gate valve piston rod slidably connected within the two-way pipe, a gate valve piston head sleeved and installed at one end of the gate valve piston rod, and a handwheel sleeved and installed at the other end of the gate valve piston rod. The handwheel is threadedly connected to the gate valve piston rod. By rotating the handwheel in the forward / reverse direction, the extension / extension of the gate valve piston rod within the two-way pipe is adjusted. The handwheel controls the gate valve piston head to push the auxiliary material located within the two-way pipe into the mixing tank.

[0007] Furthermore, the pneumatic pressing assembly also includes a guide rod, one end of which is fixedly connected to the pressing plate, and the other end of which extends out of the barrel cover and is fitted with a pointer.

[0009] Furthermore, the pneumatic pressing assembly also includes multiple fixing rods arranged in a circumferential array and vertically fixed at equal intervals on the barrel lid; one end of each fixing rod is fixed to the barrel lid, and the other end is fixed to the end cap.

[0010] Furthermore, the rotary locking assembly includes: a rotating shaft with one end fixedly connected to the bucket lid and the other end rotatably connected to the material container via a bearing, and a plurality of latch-type quick clamps equidistantly mounted on the upper end of the material container.

[0011] Furthermore, the latch-type quick clamp is provided with four.

[0012] Furthermore, the container is equipped with movable casters.

[0013] The beneficial effects of this utility model's feeding station for high-viscosity liquid additives are:

[0014] 1. This utility model uses a pneumatic pressing component to slowly inject auxiliary materials into the mixing tank from the feed port on the side wall of the mixing tank. While ensuring that the materials do not stick to the wall, they are injected and mixed simultaneously. Under the action of the stirring paddle, the injected high-viscosity materials can be quickly mixed with the materials in the tank without contacting other parts, which can effectively improve the uniformity of the slurry, improve the accuracy of the formula ratio, and greatly reduce the difficulty of cleaning the equipment.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0023] like Figures 1-3The embodiment of a feeding station for high-viscosity liquid additives of this utility model shown includes a holding tank 1, a lid 2 covering the holding tank 1, and a pneumatic pressing assembly 3 installed on the lid 2. The lid 2 is connected to the holding tank 1 via a rotation locking assembly 4. A discharge port 12 is provided at the bottom of the holding tank 1, and a feed inlet 110 is provided on the bottom side wall of the mixing tank 11. The discharge port 12 of the holding tank 1 is connected to the feed inlet 110 of the mixing tank 11 via a pipe. A gate valve assembly 5 is also installed at the feed inlet 110 of the mixing tank 11. A two-way pipe 6 is fixed at the feed inlet 110 of the mixing tank 11. One port of the two-way pipe 6 is connected to the discharge port 12 of the holding tank 1, and the other port is equipped with the gate valve assembly 5. The feeding station for high-viscosity liquid additives is used to transport high-viscosity additives into the mixing tank 11. The gate valve assembly 5 is opened, and the pneumatic pressing assembly 3 is used to press the additives into the mixing tank 11. Component 3 pumps the auxiliary material from the holding tank 1 into the mixing tank 11. After feeding is complete, the gate valve assembly 5 closes and squeezes the auxiliary material located at the feed inlet 110 of the mixing tank 11 into the mixing tank 11, achieving rapid and accurate feeding of high-viscosity liquid auxiliary material. Through the pneumatic pressing assembly 3, the high-viscosity liquid auxiliary material can be slowly injected into the mixing tank 11 at a certain speed through the feed inlet 110 on the side wall of the mixing tank 11, achieving the effect of simultaneous injection and mixing without sticking to the wall. Under the action of the stirring paddle, the injected high-viscosity material can quickly mix with the material in the tank without contacting other parts. This effectively avoids the phenomenon that when adding auxiliary material to the tank body pipe of the traditional mixer, the slurry will stick to the stirring paddle and the tank wall due to the high viscosity of the auxiliary material. It can effectively improve the uniformity of the slurry, improve the accuracy of the formula ratio, and greatly reduce the difficulty of cleaning the equipment.

[0024] The pneumatic pressing assembly 3 includes a cylinder 30 vertically and sealed to the barrel cover 2, an end cap 31 sealed to the top of the cylinder 30, and a pressing piston rod 32 installed inside the cylinder 30. One end of the pressing piston rod 32 is fitted with a pressing piston head 33, and the other end protrudes from the end cap 31 with a pressing plate 34 installed at its end. The pressing piston head 33 is slidably connected to the inner wall of the cylinder 30. The pressing piston rod 32 protrudes from the barrel cover 2, and the pressing plate 34 is installed at its end. The pressing plate 34 is located inside the holding barrel 1. The cylinder 30, end cap 31, and barrel cover 2 are also included. A closed space is formed, and gas is introduced into the cylinder 30, pressing the pressing piston downward and pushing the pressing plate 34 downward, so as to squeeze the auxiliary material in the holding tank 1 into the mixing tank 11. Through the feed port 110 on the side wall of the mixing tank 11, the high viscosity material is directly injected into the material in the mixing tank 11. Under the action of the stirring paddle, the injected high viscosity material can quickly mix with the material in the tank without contacting other parts, which can effectively improve the uniformity of the slurry, improve the accuracy of the formula, and greatly reduce the difficulty of cleaning the equipment.

[0025] The pneumatic pressing assembly 3 also includes multiple fixing rods 35 that are vertically fixed to the barrel lid 2 in a circumferential array. One end of the fixing rod 35 is fixed to the barrel lid 2, and the other end is fixed to the end cap 31. In order to facilitate the fixing of the end cap 31, multiple fixing rods 35 are vertically fixed at equal intervals on the upper surface of the barrel lid 2. The fixing rods 35 are used to support the installation of the end cap 31. In this embodiment, there are six fixing rods 35. The six fixing rods 35 are circumferentially arrayed and fixed to the barrel lid 2. The six fixing rods 35 support the end cap 31 and play a role in strengthening and stabilizing it.

[0026] The gate valve assembly 5 includes a gate valve piston rod 50 slidably connected within the two-way pipe 6, a gate valve piston head 51 sleeved and installed at one end of the gate valve piston rod 50, and a handwheel 52 sleeved and installed at the other end of the gate valve piston rod 50. The gate valve piston head 51 is located within the two-way pipe 6 and is slidably connected to the inner wall of the two-way pipe 6. The handwheel 52 is threadedly connected to the gate valve piston rod 50. By rotating the handwheel 52 in the forward / reverse direction, the piston rod is driven to extend / retract within the two-way pipe 6. The handwheel 52 controls the gate valve piston head 51 to push the auxiliary material located within the two-way pipe 6 into the mixing tank 11. By rotating the handwheel 52 to adjust the piston head, the opening / closing of the feed inlet 110 is controlled, allowing the auxiliary materials to enter the mixing tank 11 from the feed inlet 110. At the same time, the auxiliary materials located in the two-way pipe 6 can also be pushed into the mixing tank 11. This can ensure that all the materials are squeezed into the mixing tank 11, effectively reducing formula errors, improving mixing effect, and resulting in better quality slurry.

[0027] The pneumatic pressing assembly 3 also includes a guide rod 7; one end of the guide rod 7 is fixedly connected to the pressing plate 34, and the other end extends out of the lid 2 and is fitted with a pointer 8; the upper surface of the pressing plate 34 is also vertically mounted with the guide rod 7, one end of the guide rod 7 is fixedly connected to the pressing plate 34 through a mounting base, and the other end extends out of the lid 2 and is fitted with a pointer 8, which is fixedly mounted on the guide rod 7 through a pointer 8 seat; the pressing cylinder drives the pressing plate 34 to move downward, which in turn drives the guide rod 7 to move downward, and the amount of auxiliary material added can be read intuitively by the movement of the pointer 8, which is more convenient and efficient.

[0028] A scale 9 is vertically fixed on the upper surface of the lid 2. The pointer 8 is located on the side of the scale 9 with the graduation lines. The cylinder drives the pressure plate 34 to move, which in turn drives the guide rod 7 to move vertically, thereby driving the pointer 8 to move up and down. The pointer 8 and the scale 9 work together to read the reading simply and intuitively.

[0029] The rotary locking assembly 4 includes: a rotating shaft 40 with one end fixedly connected to the lid 2 and the other end rotatably connected to the container 1 via a bearing; and multiple latch-type quick clamps 41 equidistantly installed on the upper end of the container 1. The lid 2 is rotatably connected to the container 1 via the rotating shaft 40, and the rotating shaft 40 is rotatably connected to the container 1 via a bearing. Multiple latch-type quick clamps 41 are equidistantly distributed on the upper end of the container 1. In this embodiment, four latch-type quick clamps 41 are provided. By providing four latch-type quick clamps 41, the lid 2 and the container 1 can be easily and quickly fixed, preventing foreign objects from falling into the container 1 and effectively isolating debris from the external environment from entering the container 1.

[0030] To facilitate moving the material container 1, movable casters 10 are installed on the material container 1. Casters 10 are installed at the four corners of the bottom of the material container 1 to facilitate moving the material container 1.
