Description

Technical Field

[0001] The utility model relates to the technical field of glaze mixing, and more specifically to a premixed glaze preparation system. Background Art

[0002] Ceramic glazing is a process of applying glaze to the surface of ceramics to improve the appearance of ceramic products, enhance their physical properties and add decorative effects. This process is very important in ceramic craftsmanship and has both practical functions and artistic value.

[0003] Here are some of the main features and steps of ceramic glazing:

[0004] (1) Select and prepare glaze of appropriate concentration: Select appropriate glaze according to the required color, texture and firing temperature.

[0005] (2) Preparation of ceramic products: Before glazing, ceramics usually need to be bisque fired to partially sinter them and give them a certain hardness.

[0006] (3) Glazing: Glazing can be done by dipping, spraying, brushing or pouring. After glazing, the uniformity of the glaze layer needs to be carefully checked.

[0007] (4) Firing: After glazing, ceramics need to be fired a second time, a step called "glaze firing". At high temperatures, the glaze melts to form a hard glaze layer.

[0008] When glazing ceramics, selecting glazes and preparing glazes of corresponding concentrations are relatively critical steps before glazing. In existing ceramic production lines, the process of preparing glazes of corresponding concentrations still requires repeated manual adjustments. Certain parameters of the surface glaze or polishing glaze can only be obtained based on experience, vision and complex calculations, and then the glaze is modulated according to the parameters, which wastes a lot of production time and energy. In addition, the surface glaze or polishing glaze in the production line will change with the passage of time, the advancement of the glazing process, and the addition of water or glaze. The specific gravity and concentration of the glaze will change at any time. In order to ensure that the glaze meets the requirements at any time, technicians need to manually re-test the glaze parameters, recalculate and adjust them every once in a while, which greatly increases the workload of glaze preparation and brings great inconvenience to the production of ceramic products.

[0055] refer to Figure 1 The utility model provides a premixed glaze preparation system, comprising:

[0056] Central control device, mixing container, sensor assembly, water replenishment container and glaze replenishment container;

[0057] The central control device is electrically connected to the sensor assembly;

[0058] The sensor assembly includes a specific gravity sensor;

[0059] The probe of the specific gravity sensor is placed at the bottom of the mixing container, and is used to obtain current specific gravity data of the mixed material in the mixing container;

[0060] The water replenishment container and the glaze replenishment container are respectively connected to the mixing container through pipelines, and can input water and / or glaze into the mixing container under the control of the central control device.

[0061] The above-mentioned central control device is used to control the premixed glaze preparation system as a whole. The current specific gravity data of the mixed material in the mixing container is obtained through the specific gravity sensor in the sensor assembly, and the current concentration is calculated through the current specific gravity data. The current concentration is compared with the standard concentration. If it is judged to be unqualified, the corresponding water and / or glaze replenishment amount is calculated, and according to the replenishment amount, the water replenishment container and the glaze replenishment container are controlled to replenish the mixing container through the pipeline so as to reach the standard concentration.

[0062] As mentioned above, the sensor assembly includes a specific gravity sensor, which is provided with a probe. The probe can be arranged at the bottom of the mixing container so as to better collect the specific gravity data of the mixed material therein.

[0063] In the above, the water replenishment container stores water for mixing, and the glaze replenishment container stores glaze for mixing. The two containers are connected to the mixing container through corresponding pipelines, and the release and stop of water and glaze are controlled by the central control device.

[0064] In the premixed glaze preparation system provided by the utility model, the current specific gravity data of the mixed glaze in the mixing container is obtained in real time or at a fixed time by the specific gravity sensor in the sensor assembly, and the current concentration value can be calculated based on the data. When the concentration value does not meet the standard, the central control device controls the water replenishment container and the glaze replenishment container to introduce water and / or glaze through the pipeline for replenishment. The utility model realizes unattended automatic detection, calculation, judgment and preparation of the mixed glaze, reduces production costs, improves work efficiency, improves the accuracy of preparation, and brings great convenience to ceramic production.

[0065] Furthermore, the mixing container is connected with a quantitative water injection valve and a quantitative glaze adding valve;

[0066] The quantitative water injection valve and the quantitative glaze adding valve are both electrically connected to the central control device;

[0067] The quantitative water injection valve is connected to the water replenishment container through a water injection pipeline;

[0068] The quantitative glaze adding valve is connected to the glaze filling material container through a glaze adding pipeline.

[0069] As mentioned above, in order to better control the release amount of the water replenishment container and the glaze replenishment container, in the utility model, a quantitative water injection valve and a quantitative glaze adding valve are arranged on the mixing container. On the one hand, both valves are electrically connected to the central control device, and on the other hand, they are connected to the water replenishment container and the glaze replenishment container through pipelines.

[0070] Specifically, the water replenishment container is connected to the water filling pipeline and then connected to the water filling valve; the glaze replenishment container is connected to the glaze adding pipeline and then connected to the glaze adding valve.

[0071] Furthermore, the sensor assembly also includes a flow rate sensor;

[0072] The probe of the flow rate sensor is placed at the bottom of the mixing container.

[0073] As mentioned above, the sensor may also include a flow rate sensor, the probe of which may also be arranged at the bottom of the mixing container, for the central control device to collect the flow rate of the mixed material in real time or at a fixed time. If the flow rate is too fast, it is compared with the standard flow rate, and if it is greater than the standard flow rate, it means that there is too much water in the mixed material, resulting in a low material concentration. Further calculations are then performed based on the current specific gravity data to determine whether there is a problem of too low concentration. If so, the water replenishment container and the glaze replenishment container are used for corresponding replenishment.

[0074] For further reference, Figure 2 , the central control device includes a processor, and a storage module, a control module and a display connected to the processor via a bus;

[0075] The sensor component is electrically connected to the processor via the bus.

[0076] In the above, the central control device may include a bus, through which the processor and other devices are connected. The bus may be connected to a storage module, a control module, and a display. The storage module may be a solid state drive, a memory card, a mechanical hard drive, or a cloud storage space, etc.

[0077] The control module can be a keyboard, mouse, joystick, joystick, joystick button, etc.; the display can be a conventional display screen or a touch screen; in addition, it can also include a power supply, a wireless network card, etc., to achieve network connection, such as controlling the system and acquiring data through an APP, etc.

[0078] For further reference, Figure 3 , the mixing container comprises a mixing main cylinder, and a premixing component connected to the mixing main cylinder;

[0079] Wherein, the water replenishment container and the glaze replenishment container are both connected to the premixing component.

[0080] As mentioned above, when replenishing materials, the glaze can be in the form of dry powder or semi-fluid solid containing a certain amount of water. If it is directly added to the mixing main cylinder, it will take a certain amount of time to mix evenly, and due to its own characteristics, the mixing efficiency will be greatly reduced.

[0081] In order to mix the mixed materials in the mixing container more quickly and evenly, in the utility model, in terms of control, firstly, by calculating each time when replenishing materials, a certain proportion of water can be replenished while replenishing glaze, and then, at the hardware structure level, the mixing container is divided into two parts, namely, a mixing main cylinder and a premixing component. Among them, the premixing component is connected to the water replenishment container and the glaze replenishment container, and is used to receive the materials replenished by the water replenishment container and the glaze replenishment container, and premix the replenished water and glaze to achieve the purpose of mixing.

[0082] The mixing main cylinder is connected to the premixing component and can receive the supplementary material after the premixing process of the premixing component, and then mix the supplementary material with the original mixed material to achieve the purpose of uniform mixing.

[0083] Further, the premixing assembly includes a spray chamber, and a mixing chamber connected to the spray chamber;

[0084] The spray chamber is connected to both the water replenishment container and the glaze replenishment container;

[0085] The mixing chamber is connected to the mixing main cylinder.

[0086] The premixing assembly is used to more fully premix the supplemented water and glaze.

[0087] Structurally, it consists of two main parts, namely the spray chamber and the mixing chamber.

[0088] The spray chamber is connected to the water replenishment container and the glaze replenishment container, and is used to input the water and glaze to be replenished therein. The mixing chamber is used to mix the input water and glaze, and after mixing evenly, input them into the mixing main body cylinder behind, so as to avoid directly inputting high-concentration glaze or dry glaze into the mixing main body cylinder, which will cause the problem of greatly reducing the mixing efficiency.

[0089] As mentioned above, when the spray room receives the water and glaze that need to be replenished, the materials can be preliminarily mixed by spraying.

[0090] For further reference, Figure 4 The spray chamber is provided with a connecting nozzle, a spray shower and a glaze feeding head;

[0091] The glaze feeding head is connected to the glaze filling container;

[0092] One end of the connecting nozzle is connected to the water replenishment container, and the other end is connected to the spray shower;

[0093] The size of the spray shower is matched with the size of the spray chamber, so that the water sprayed by the spray shower can spray the glaze in the spray chamber.

[0094] As mentioned above, the connecting nozzle is connected to the spray shower, so as to spray the glaze outputted from the glaze feeding head.

[0095] In order to flush all glazes, a spray shower can be set on one inner wall of the spray room and be close to the size of the spray room, so that the glazes at various angles and positions in the spray room can be flushed and the glazes can be fully mixed with water.

[0096] For further reference, Figure 5 , the mixing chamber comprises a flat silo body, and at least one set of stirring wheels arranged in the flat silo body;

[0097] The flat silo is vertically arranged and is provided with an inlet and an outlet; wherein the inlet is arranged at the upper end of the flat silo and is connected to the spray chamber; the outlet is arranged at the bottom end of the flat silo;

[0098] The rotating plane of the stirring wheel is parallel to the horizontal plane of the flat warehouse body.

[0099] The above-mentioned flat silo has at least one set of stirring wheels placed horizontally, which can be magnetically suspended or driven by a motor through a belt. Through the rotation of the stirring wheel, the mixed material input into the spray chamber through the feed inlet can be sprayed and received and input into the flat silo.

[0100] The overall shape of the flat bin is flat, wherein a plurality of groups of stirring wheels may be arranged in the horizontal direction, and the rotation directions of different stirring wheels may be the same or different.

[0101] The flat shape helps the horizontally placed stirring wheel to better mix the incoming materials, allowing the materials to fully contact the horizontal stirring wheel to achieve stirring and kneading of the materials, thereby achieving the purpose of uniform mixing.

[0102] Furthermore, the mixing chamber further comprises a circulation pipeline and a delivery pump connected to the circulation pipeline;

[0103] One end of the circulation pipeline is connected to the bottom end of the flat silo, and the other end is connected to the feed port, so that the material in the mixing chamber can be introduced from the bottom end of the circulation pipeline through the feed port into the top end of the mixing chamber for re-mixing.

[0104] As mentioned above, in order to further improve the efficiency of premixing and avoid the situation where some materials in the flat silo are mixed but some are not mixed, in the mixing chamber of the present embodiment, a circulation pipeline is connected to the bottom end of the flat silo, and is connected to the feed port position at the upper end of the flat silo through a connecting pipeline, so that the mixed materials in the flat silo can be passed through the circulation pipeline, and under the power output of the dewatering pump, the materials therein are reintroduced from the feed port at the upper end through the pipeline, and the stirring of the agitator wheel is reused, so as to achieve the purpose of remixing, realize sufficient premixing and processing of the materials, and improve the mixing efficiency.

[0105] As mentioned above, the flat silo can be arranged vertically. An inlet is arranged at the upper end, an outlet is arranged at the lower end, and a circulating pipeline is connected to the lower end. After the material to be mixed enters from the inlet at the upper end, it can be rotated and stirred by each stirring wheel in turn under the action of gravity, and enter the lower end, through the circulating pipeline at the lower end, under the action of the outlet pump, it is sucked to the upper end, and enters the flat silo again through the inlet, and is mixed again one or more times, so as to achieve the purpose of uniform mixing, until a certain number of cycles or cycle time is reached, and then it is led out through the outlet and enters the mixing main cylinder to complete the premixing process.

[0106] For further reference, Figure 6 , the mixing main cylinder comprises a cylinder body; a mixing rotor is arranged in the cylinder body;

[0107] A plurality of feeding input pipes are arranged at the top and bottom of the cylinder body; and the feeding input pipes are connected with the discharge port of the mixing chamber.

[0108] As mentioned above, a mixing rotor is provided in the cylinder body of the mixing main cylinder for continuously or regularly stirring the mixed material therein to prevent the material from settling, agglomerating, and agglomerating, which would lead to uneven mixing.

[0109] A plurality of feeding input pipes for premixed materials are arranged at different positions of the cylinder body, and the feeding input pipes can spray the materials into the cylinder body under the action of a pump.

[0110] The feeding input pipe is arranged at the upper end and the lower end of the cylinder body. The different positions can better input the materials to different positions of the cylinder body. The feeding input pipe is connected to the discharge port of the mixing chamber.

[0111] Although the present invention has been disclosed as above with preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art may make some modifications and improvements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the definition of the claims.
