Abstract
Description
Technical Field
[0001] This invention provides a mixer for preparing medical device dressings, belonging to the field of dressing preparation mixing technology. Background Technology
[0002] Medical device dressings are medical auxiliary materials used to cover wounds or sores. Their core component is medical absorbent gauze, and their main functions include hemostasis, absorption of exudate, and promotion of healing. During the preparation of medical device dressings, a mixer is typically used to combine various dressing ingredients.
[0003] Existing mixing equipment often suffers from the following problems: high risk of material blockage; traditional mixing tanks have simple inlet and outlet structures and lack anti-blockage design, making it easy for viscous materials to accumulate at the inlet and outlet, leading to process interruption; and since various medical device dressing raw materials are added to the mixing tank in batches one by one through the inlet, stratification of various medical device dressing raw materials may occur within the mixing tank, making it difficult to fully achieve uniform mixing of multi-component materials, thus requiring improvement in performance. Based on this, this utility model provides a mixer for preparing medical device dressings. Utility Model Content
[0004] The technical problem solved by this utility model is that the risk of blockage in the inlet and outlet of various medical device dressings is high, and the various medical device dressings added to the mixing tank in sequence are prone to stratification in the mixing tank, making it difficult to fully achieve uniform mixing of multi-component materials.
[0005] To solve the technical problem, the technical solution provided by this utility model is as follows: a mixer for preparing medical device dressings, including a mixing tank, a discharge port at the bottom of the mixing tank, several material barrels arranged around the upper circumference of the mixing tank, a vertical inclined feed pipe connected to the top of the mixing tank at the bottom of the material barrels, an anti-clogging stirring assembly on the mixing tank, the anti-clogging stirring assembly including a second spiral auger located inside the discharge port, a stirring rod passing through the top of the second spiral auger, a first spiral auger inside the lower vertical pipe of the vertical inclined feed pipe, and a driving assembly for driving the first spiral auger and the stirring rod to rotate at the top of the mixing tank.
[0006] Furthermore, the drive assembly includes a support frame fixedly mounted on the top of the mixing tank and positioned between the vertical and inclined feed pipes. A protective shell is provided on the top of the support frame, and a motor is provided on the top of the protective shell. The top end of the stirring rod passes through the support frame, is inserted into the protective shell, and is fixedly connected to the output end of the motor. A main gear is provided on the body of the stirring rod and is placed inside the protective shell. A rotating rod is rotatably connected to the top of the support frame and is placed on one side of the auger. A middle gear is provided on the top of the rotating rod and meshes with the main gear. The top end of the auger is inserted into the protective shell and is provided with a driven gear that meshes with the middle gear.
[0007] Furthermore, the top of the protective shell is provided with several heat dissipation holes.
[0008] Furthermore, the discharge port is equipped with a slide valve located below the spiral auger, and the vertical inclined discharge pipe is equipped with a switch valve located above one side of the spiral auger.
[0009] Furthermore, the number of material hoppers is 3-5, the top of each material hopper is provided with a feeding port, and the material hopper is provided with a level gauge for monitoring the position of the material inside the hopper.
[0010] Furthermore, an observation window is provided on the outer wall of the mixing tank.
[0011] Furthermore, the vertical inclined feed pipe is provided with a through-hole that is rotatably connected to the auger.
[0012] Furthermore, the stirring rod has several stirring blades equidistantly arranged on both sides of the rod body, which are placed inside the mixing tank.
[0013] The beneficial effects of this utility model are: Three to five feed hoppers simultaneously feed various medical device dressing raw materials into the mixing tank. Combined with an anti-clogging mixing component, the drive unit drives the mixing rod, auger two, and auger one to operate in tandem. Auger one rotates to forcefully push the material from the vertically inclined feed pipe downwards, preventing clogging. Auger two rotates to lift and prevent clogging of the material in the bottom discharge area. The mixing rod drives the mixing blades to rotate, achieving mixing and blending of the various medical device dressing raw materials added simultaneously into the mixing tank. This prevents the various medical device dressings from separating within the mixing tank, greatly improving the effectiveness of the treatment. Attached Figure Description

Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail here.
[0027] The principle of this utility model During use, the level gauge 19 monitors the material quantity in the material hopper 2 in real time, and automatically starts and stops the feeding process in conjunction with the controller, reducing manual intervention. 3-5 material hoppers 2 simultaneously feed various medical device dressing raw materials into the mixing tank 1 through vertical and inclined feed pipes 3. Through the drive component 8, the motor 11 drives the stirring rod 6, the main gear 12, and the spiral auger 5 to rotate. Together with the driven gear 15 and the middle gear 14, the spiral auger 7 in each vertical and inclined feed pipe 3 works in coordination. The rotation of the spiral auger 7 is used to forcefully push the material in the vertical and inclined feed pipe 3 downward to avoid the accumulation and blockage of viscous materials in the pipe. The rotation of the spiral auger 5 is used to lift and prevent blockage of the material in the bottom discharge area. The rotation of the stirring rod 6 drives the stirring blade 22 to rotate, realizing the mixing of various medical device dressing raw materials added at the same time in the mixing tank 1, so as to prevent the various medical device dressings from separating in the mixing tank 1, and greatly improving the use effect.
