Description

Technical Field

[0001] This utility model relates to the field of daily chemical production equipment technology, and in particular to a multifunctional intelligent dispensing device for daily chemical detergents. Background Technology

[0002] The core of the production process of daily chemical detergents (such as laundry detergent, dishwashing liquid, industrial cleaning agents, etc.) lies in the precise proportioning and uniform mixing of various forms of raw materials. The product performance (detergent power, stability, mildness) directly depends on the accuracy of the addition and the mixing quality of solid raw materials (laundry aids, powder additives, etc.) and liquid raw materials (surfactants, fragrances, preservatives, etc.).

[0003] However, in the existing technology, some small and medium-sized daily chemical enterprises still generally adopt the production method of manual weighing and manual feeding. Operators need to weigh solid raw materials with a platform scale, measure liquid raw materials with a measuring cylinder, and then manually pour them into the mixing container for mixing. This method is prone to some defects: the error rate of manual operation is relatively large, and problems such as mismatch, omission, or inaccurate weighing are likely to occur, resulting in fluctuations in the detergency of the product and a shortened shelf life (such as excessive liquid raw materials causing stratification and odor). Therefore, a multifunctional intelligent mixing device for daily chemical detergents is proposed. Utility Model Content

A control panel is installed at the front end of the support frame. A first storage tank and a second storage tank are installed through the upper end of the support frame. A support plate is installed in the middle of the support frame. A metering pump is installed at the upper end of the support plate. A conveying cylinder is arranged above the support plate. A special-shaped guide tube and a connecting pipe are installed through the outer wall of the mixing tank of the mixing mechanism. A spiral conveying disc is arranged inside the conveying cylinder. A discharge disc is installed at one end of the conveying cylinder. A cylinder is installed at one end of the discharge disc. A concave rod is installed at the extended end of the cylinder. A weighing component is installed at one end of the concave rod. A flow meter is installed at the upper end of the connecting pipe.

[0006] Preferably, the outer wall of the conveying cylinder is equipped with two sets of support seats, the other end of the conveying cylinder is equipped with a servo motor, one end of the spiral conveying disc transmission rod passes through one end of the conveying cylinder and is fixed to the output end of the servo motor.

[0008] Preferably, a portion of the weighing component is inserted into the guide hole, and the weighing component is located on the discharge port side of the conveying cylinder. The servo motor and cylinder are both connected to the control panel via signal.

[0009] Preferably, the discharge end of the second storage tank is fixed to the inlet end of the metering pump, and the upper end of the connecting pipe is fixed to the lower end of the flow meter.

[0023] Two sets of support seats 9 are installed on the outer wall of the conveying cylinder 8. A servo motor 10 is installed at the other end of the conveying cylinder 8. One end of the transmission rod of the spiral conveying disc 12 passes through one end of the conveying cylinder 8 and is fixed to the output end of the servo motor 10. A guide hole 13 is opened through the outer wall of the feeding disc 14. The discharge end of the first storage tank 5 is fixed to the feed end of the conveying cylinder 8.

[0024] The discharge end of the second storage tank 6 is fixed to the inlet end of the metering pump 7. The upper end of the connecting pipe 18 is fixed to the lower end of the flow meter 19. The upper end of the flow meter 19 passes through the lower end of the support plate 4 and is fixed to the discharge end of the metering pump 7. Both the metering pump 7 and the flow meter 19 are connected to the control panel 3 for signal connection.

[0025] The mixing mechanism 2 is located inside the support frame plate 1, and the mixing mechanism 2 is connected to the control panel 3 via signal.

[0026] The specific settings and functions of this embodiment are described in detail below. The support frame plate 1 is made of carbon steel and is formed into a vertical frame structure. The control panel 3 is fixed at the front end. Two mounting holes for the storage tanks are opened at the top to ensure that the No. 1 storage tank 5 and the No. 2 storage tank 6 are vertically fixed and the discharge end faces downward. The middle horizontal support plate 4 is welded. The support plate 4 is made of 304 stainless steel and the surface is treated with anti-slip treatment to provide load-bearing support for components such as the metering pump 7 and the conveying cylinder 8.

[0027] The control panel 3 adopts an industrial touch screen with integrated physical buttons. It has a built-in PLC controller and formula database, and can display parameters such as raw material inventory, metering data, and stirring speed. It supports manual setting of production batch quantity and establishes signal connection with servo motor 10, cylinder 15, metering pump 7, flow meter 19 and stirring and mixing mechanism 2 to realize full-process automated control.

[0028] Storage Unit: Storage Tank 5 has a mirror-polished inner wall and a feed inlet with a filter screen on the top. A capacitive level transmitter is installed on the top of the tank for storing solid raw materials (such as detergents and powder additives). Its discharge end is fixed to the feed end of the conveyor cylinder 8 via a flange, and a manual gate valve is provided at the connection to cut off the raw material supply in an emergency. Storage Tank 6 is made of the same material as Storage Tank 5, with an additional rock wool insulation layer on the outside. It has an internal electric heating element and a PT100 temperature sensor, making it suitable for storing liquid raw materials (such as surfactants and fragrances), especially to prevent solidification of raw materials at low temperatures. Its discharge end is connected to the feed end of the metering pump 7 via a food-grade hose, and the hose is wrapped with an anti-aging protective sleeve.

[0029] Metering and conveying unit: Solid metering and conveying components: The inner wall of the conveying cylinder 8 is treated with an anti-stick coating; the spiral conveying disc 12 is made of wear-resistant nylon material to ensure no residue during feeding; the servo motor 10 is fixed to the transmission rod of the spiral conveying disc 12 through a coupling; the two sets of support seats 9 are L-shaped stainless steel structures and are fastened to the support plate 4 with bolts to achieve horizontal support of the conveying cylinder 8; the discharge disc 14 has a conical structure; the guide hole 13 is an oblong hole; the weighing component 17 uses an electronic weighing sensor and is located directly below the discharge port of the conveying cylinder 8; the extended end of the cylinder 15 is connected to the concave rod 16 through a pin, which can drive the weighing component 17 to reciprocate along the guide hole 13 to complete the receiving, weighing and unloading actions;

[0030] Liquid metering and conveying assembly: includes metering pump 7, connecting pipe 18, and flow meter 19. Metering pump 7 is a servo metering pump 7; connecting pipe 18 is made of food-grade stainless steel; flow meter 19 is a Coriolis mass flow meter, which can detect the liquid raw material conveying volume in real time; the discharge end of storage tank 6 → the inlet end of metering pump 7 → the discharge end of metering pump 7 → the upper end of flow meter 19 → the lower end of flow meter 19 → connecting pipe 18 → stirring and mixing mechanism 2, forming a complete liquid conveying chain.

[0031] The mixing mechanism 2 consists of a 50L double-layer stainless steel mixing tank with a mirror-polished inner layer and an outer layer filled with insulation cotton. Two inlets are located at the top of the mixing tank, fixed to the lower ends of the shaped guide tube 11 and the connecting pipe 18, respectively. The shaped guide tube 11 is a stainless steel bend, with its upper end connected to the discharge end of the feeding tray 14 via a flange, guiding solid raw materials smoothly into the mixing tank. The mixing tank is equipped with a liftable combined mixing paddle (including an upper propeller and a lower anchor paddle). An integrated sensor is also installed inside the tank to simultaneously detect material viscosity, and the detection data is transmitted to the control panel 3 in real time.

[0032] The operation and working principle of this device are as follows: Raw material storage adaptation: The operator adds solid raw materials (such as detergent powder) to storage tank 5 through the feeding port and liquid raw materials (such as surfactants) to storage tank 6. The 316L stainless steel material and mirror-polished inner wall of the two types of storage tanks can avoid raw material contamination and residue; the liquid level transmitter in the tank detects the raw material level in real time and transmits the data to the control panel 3. When the level is lower than the preset threshold, the touch screen will automatically pop up a feeding reminder.

[0033] Then, the solid raw material metering process: Start the conveying: The operator selects the preset formula (such as "basic detergent") and sets the production batch quantity through the control panel 3. After the PLC controller calculates the required weight of the solid raw material, it sends a start signal to the servo motor 10.

[0034] Screw feeding: Servo motor 10 drives screw conveyor disc 12 to rotate at a preset speed, and solid raw materials in storage tank 5 move forward along conveyor cylinder 8 under the push of screw blades;

[0035] Weighing feedback: The raw material falls from the discharge port of the conveyor cylinder 8 into the arc-shaped receiving hopper of the weighing component 17. The electronic weighing sensor transmits the weight data to the control panel 3 in real time. When the weight reaches the preset value, the PLC controller immediately sends a stop signal, the servo motor 10 stops running, and the feeding action is terminated.

[0036] Material unloading preparation: After weighing is completed, the control panel 3 sends a telescopic command to the cylinder 15. The extended end of the cylinder 15 pushes the concave rod 16, which drives the weighing component 17 to move along the guide hole 13 of the unloading tray 14 until the material on the weighing component 17 is discharged from the discharge end of the unloading tray 14.

[0037] Liquid raw material metering process: Synchronous start: At the same time as the solid raw material feeding starts, the PLC controller sends an operation signal to the metering pump 7, and the liquid raw material in the second storage tank 6 enters the servo metering pump 7 through the food-grade hose;

[0038] Flow control: Metering pump 7 delivers raw materials at a preset flow rate. When the raw materials flow through Coriolis mass flow meter 19, the flow meter 19 detects the actual delivery volume in real time and feeds it back to control panel 3. If there is a deviation between the detected value and the preset value, the PLC controller immediately adjusts the speed of metering pump 7 to correct the flow rate and ensure delivery accuracy.

[0039] Pipeline transport: The liquid raw material, after being calibrated by the flow meter 19, flows to the stirring and mixing mechanism 2 through the connecting pipe 18. The smooth inner wall of the stainless steel pipeline reduces the adhesion of raw materials and ensures the accuracy of measurement.

[0040] Solid feeding: Solid raw materials fall into the special-shaped conduit 11 through the feeding tray 14. The stainless steel bent pipe guides the raw materials to slide down smoothly, avoiding dust flying or material accumulation during feeding; Liquid feeding: Liquid raw materials are directly injected into the mixing tank of the mixing mechanism 2 through the connecting pipe 18, ensuring that the two types of raw materials are initially gathered in the tank and mixed inside the mixing mechanism 2.

[0041] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
