Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of material moisture content control in intensive mixers, and particularly relates to a horizontal intensive mixer with moisture content adjustment. BACKGROUND

[0002] The horizontal intensive mixer can automatically stir and mix several materials with different particle sizes in a short time, saves labor cost, and can realize relatively large uniform distribution rate compared with manual stirring and mixing. In addition, the horizontal intensive mixer has the advantages of small volume, small floor area, safe and reliable work, etc. This also makes it play a very important role in the fields of chemical fertilizer, building material, metallurgy, etc. The structure mainly includes a cylinder and a stirring shaft, and a plurality of plows are installed on the stirring shaft. The plows are spirally distributed on the stirring shaft as a whole, and the plows are divided into forward and reverse plows (located in the feeding section, usually 11) and scraping plows (located in the discharging section, usually 3).

[0003] According to relevant research papers, the wear rate and service life of the plows, the mixing uniformity of the materials, and the running power of the intensive mixer are all greatly related to the moisture content of the materials during the mixing and stirring of the materials by the horizontal intensive mixer.

[0004] However, the traditional water adding method of the mixer is usually to directly add water at the feeding port. This water adding method relies on the experience judgment and manual calculation of workers to add water in proportion. This water adding method usually causes large errors, and the water adding method also causes uneven water adhesion of the granular materials, thereby causing uneven mixing of the materials. The minimum average wear depth of the plows corresponding to the moisture content of the materials is different for different purposes. For example, when the moisture content of the sintering raw materials in the field of mineral metallurgy is 0%, the average wear depth of the forward and reverse plows is the smallest, and the wear depth increases with the increase of the moisture content of the sintering raw materials. The minimum average wear depth of the scraping plows corresponds to the moisture content of the sintering raw materials of 7%. If the moisture content is higher or lower than this percentage, the average wear depth of the scraping plows will increase to different degrees. When the moisture content of the sintering raw materials is 7%, the mixer reaches the peak power. If the moisture content is lower or higher than this value, the power of the mixer will decrease to different degrees.

[0005] According to the above conclusion, if the moisture content of the materials in different regions of the mixer cannot be controlled, the average wear depth of the scraping plows and the forward and reverse plows cannot reach the optimal expected value. In actual production, it is often expected that the average wear depth of the forward and reverse plows is the smallest, because the number of the forward and reverse plows is the largest. When the forward and reverse plows all have large wear, the uniformity of the material mixing will greatly decrease and the working time will also increase accordingly. The cost of repairing or replacing the plows will also greatly increase. The intensive mixer technology urgently needs a device that can control the moisture content in different regions of the mixer to realize the optimal distribution of the average wear depth of the scraping plows and the forward and reverse plows.

[0038] A feeding port 1-2 for feeding the forward and reverse pushing plow area is arranged at the left top of the cylinder main body 1-1, a discharging port 1-4 for discharging the material in the material scraping plow area is arranged at the right side of the cylinder main body 1-1, the material scraping plows 2-5 in the material scraping plow area are provided with water permeation devices for supplementing water to the material, and humidity sensors 1-3 for detecting humidity are installed in the cylinder main body 1-1 in the material scraping plow area.

[0039] In order to improve the measurement accuracy, the three humidity sensors 1-3 are uniformly distributed on the circumference of the cylinder main body 1-1 in the embodiment. In actual application, four or six humidity sensors or the like can also be used, and the specific number can be determined according to the inner diameter size of the cylinder main body 1-1 and the like.

[0040] The water permeation devices in the embodiment can adopt the following modes, as shown in Figure 3 ,

[0042] The water supply main pipe 3-5 is installed on the central rotating shaft 2-1, and the water supply branch pipe 3-4 is installed on each plow arm 2-3 in the area of the material scraping plow, and the electromagnetic valve is installed on the water supply branch pipe 3-4, and the water supplement opening for supplementing water to the material is opened on the material scraping plow 2-5, the water outlet end of the water supply branch pipe 3-4 is connected and communicated with the water inlet end of the water supplement opening, the water inlet end of the water supply branch pipe 3-4 is connected and communicated with the water supply main pipe 3-5, and the water inlet opening is arranged on the water supply main pipe 3-5.

[0043] II. The water permeation device comprises a water storage cavity opened in the central rotating shaft 2-1, a water inlet opening 2-8 is opened on the central rotating shaft 2-1 to supplement water to the water storage cavity, and a water supplement opening is opened on each material scraping plow 2-5 to supplement water to the material, a water supplement channel is opened on the corresponding plow arm 2-3 corresponding to the water supplement opening, and the water supplement channel is connected and communicated with the water storage cavity and the water supplement opening respectively, and the electromagnetic valve is installed on the water supplement channel.

[0044] III. The water permeation device comprises a water supply main pipe 3-5, the water supply main pipe 3-5 is a water storage cavity opened in the central rotating shaft 2-1, a water inlet opening 2-8 is opened on the central rotating shaft 2-1 to supplement water to the water storage cavity, and a water supplement opening is opened on each material scraping plow 2-5 to supplement water to the material, each water supplement opening is connected and communicated with the water supply main pipe 3-5 through a water supply branch pipe 3-4, the water supply branch pipe 3-4 is embedded in the corresponding plow arm 2-3, and the electromagnetic valve is installed on the water supply branch pipe 3-4.

[0045] A plug (also called a silk plug, or a rubber plug) is arranged at the water inlet opening, when water needs to be added, the plug is removed, water is added to the water storage cavity through the water inlet opening, and after completion, the plug is plugged into the water inlet opening.

[0046] The above-mentioned electromagnetic valve is a common and common direct-acting one-way valve, in order to be further applicable to the design, the embodiment provides a new electromagnetic valve, the electromagnetic valve comprises a valve 3-1, the valve 3-1 is a plate-shaped structure, the valve 3-1 is located outside the material scraping plow 2-5 at the water outlet end of the water supplement opening, when the water supplement opening needs to be blocked, the valve 3-1 is tightly attached to the outer wall of the material scraping plow 2-5, an electromagnetic valve core 3-2 is independently arranged in the water supplement opening, one end of the electromagnetic valve core 3-2 is fixed with the valve 3-1, and the other end of the electromagnetic valve core 3-2 is provided with a spring valve seat 3-3 for driving the electromagnetic valve core 3-2 to move in the water supplement opening through electromagnetic force.

[0047] In production, the spring valve seat 3-3 can be installed in the water supply opening, the water supply branch pipe 3-4 or the water supply channel according to actual conditions; or an installation cavity for installing the spring valve seat 3-3 can be formed at the material scraping plow 2-5 beside the water supply opening, the electromagnetic valve core 3-2 is "Z", the top horizontal section is located in the water supply opening, the bottom horizontal section is located in the installation cavity and is in magnetic force driving cooperation with the spring valve seat 3-3, and a sliding groove for the middle section of the electromagnetic valve core 3-2 to slide back and forth is formed in the material scraping plow 2-5 between the installation cavity and the water supply opening.

[0048] The new electromagnetic valve also adopts the purpose of driving the valve core to run by magnetic force to achieve the opening and closing of the electromagnetic valve. The electromagnetic valve core 3-2 is in clearance cooperation with the spring valve seat 3-3. After power-on, under the action of electromagnetic force, the electromagnetic valve core 3-2 can drive the valve 3-1 to move towards the material scraping plow 2-5, and finally make the valve 3-1 tightly adhere to the outer wall of the material scraping plow 2-5, which limits the water to flow out from the water supply opening, and the fine particles cannot enter the water supply opening from the outside of the valve;

[0049] In order to further ensure the sealing effect, the valve 3-1 and the material scraping plow 2-5 are provided with a water blocking gasket 3-6 for sealing.

[0050] The valve 3-1 is a circular metal sheet, which can be welded with the electromagnetic valve core 3-2 to become an integral structure, in a normally closed state, tightly combined with the water blocking gasket 3-6 to ensure that there is no water leakage when no water supply instruction is received.

[0051] When water needs to be supplied, the spring valve seat 3-3 is powered off, the magnetic effect disappears, the electromagnetic valve core 3-2 is ejected, the valve 3-1 is opened, under the high-speed rotation of the center shaft 2-1, the water flow is brought to the electromagnetic valve by centrifugal force, and the water flow can seep out from the water supply opening, which is the opening of the water seepage device;

[0052] When the spring valve seat 3-3 is powered, the electromagnetic valve core 3-2 is firmly attracted to the spring valve seat 3-3, at this time, the valve 3-1 is also driven to tightly combine with the water blocking gasket 3-6, which can prevent water from seeping out or material from entering to prevent the waterway from being blocked, and the water seepage device is closed.

[0053] In order to realize automatic control, the embodiment also includes a control system, which is used to judge whether to open the electromagnetic valve after receiving the signal of the humidity sensor 1-3. The control system is a programmable logic controller PLC.

[0054] The specific method of the control system for judging whether to open the electromagnetic valve after receiving the signal of the humidity sensor 1-3 is:

[0055] I. Set the wear data of the scraping plow 2-5 and the corresponding material filling rate, the rotation speed of the central rotating shaft 2-1 and the water penetration speed in the operation of the intensive mixer as sample data; the source of the wear data of the scraping plow 2-5 is set as follows: the historical operation data of the intensive mixer is experimented and mechanically simulated, and the data corresponding to the preset wear degree of the scraping plow 2-5 is selected as the wear data of the scraping plow 2-5.

[0056] II. Train the radial basis function neural network model by using the sample data in step I;

[0057] The radial basis neural network is an artificial neural network model with a forward propagation structure, and its network structure includes an input layer, a hidden layer and an output layer. The neurons in the hidden layer use radial basis functions as activation functions, and the output layer is usually a linear layer. This network structure is different from the traditional multilayer perceptron because its hidden layer has no activation function but performs nonlinear mapping through radial basis functions. Each hidden layer neuron has a center vector, which represents the neuron's response to the input space. The input sample activates the hidden layer neurons by calculating the distance between the center vector, the closer the distance, the higher the activation degree. The process of training the radial basis neural network includes determining the center vector of the hidden layer and calculating the weight of the output layer, and a clustering algorithm is usually used to select the center vector of the hidden layer. Once the center vector is determined, the least squares method or other optimization algorithms can be used to calculate the weight of the output layer. In the mixing process, the material filling rate in the barrel 1-1 of the intensive mixer, the rotation speed of the central rotating shaft 2-1 and the flow of the water penetration device 3 have a great influence on the material humidity signal. The relationship between each parameter and the material humidity signal is difficult to determine, so the radial basis neural network prediction model is used to map the internal relationship and approximate the nonlinear function coupled with the above parameters with arbitrary precision. The training set of the radial basis function neural network prediction model is derived from the experimental data and mechanical simulation results of the water content of the sintered material, the wear depth and service life of the plow. The material filling rate, the rotation speed of the central rotating shaft and the water penetration speed in several groups of data are taken as inputs and normalized, and the corresponding general material humidity signal is taken as output. Through the training of sample data, the network weight and threshold are constantly corrected to make the error function descend along the negative gradient direction, and the expected output is approximated. The number of nodes in the input layer of the model is 3, and the number of nodes in the output layer is 1, as shown in Figure 4 .

[0058] III. Collect the material filling rate, the rotation speed of the central rotating shaft 2-1 and the water penetration speed and the humidity value of the humidity sensor 1-3 in the operation of the intensive mixer;

[0059] IV. Input the collected operation parameters in step III into the radial basis function neural network model trained in step II to obtain the preset humidity threshold.

[0060] V. Judgment of contrast, when the humidity value of humidity sensor 1-3 in step three is less than the preset humidity threshold in step four, the control system opens the electromagnetic valve (note that the electromagnetic valve here is the application of the existing known technology, if the new electromagnetic valve in this embodiment is applied, the spring valve seat 3-3 should be de-energized), the water infiltration device works to supplement water, until the humidity value of humidity sensor 1-3 in step three is greater than or equal to the preset humidity threshold in step four, the control system closes the electromagnetic valve (note that the electromagnetic valve here is the application of the existing known technology, if the new electromagnetic valve in this embodiment is applied, the spring valve seat 3-3 should be energized), the water infiltration device stops working, as shown in Figure 5 .

[0061] In this embodiment, the material filling rate, the rotational speed of the central rotating shaft 2-1 and the water infiltration speed are used as operating parameters. In actual application, other data related to the wear of the material scraping plow 2-5 can also be added.
