[0067] Based on the above structural features of the present application, the implementation methods of the present application are further described:

[0068] Reference Figures 1 and 2 This embodiment provides a slurry particle washing device, comprising a hydrocyclone separator 1, which includes a cyclone drum 11, a feed pipe 12, a discharge pipe 13, an overflow pipe 14, and a connecting pipe 15. The feed pipe 12 is fixedly connected to and communicates with the top of the cyclone drum 11 (e.g., via an integral seal or welded seal). The upper portion of the cyclone drum 11 is a straight cylindrical shape with a fixed diameter, and the lower portion is an inverted cone. The upper and lower portions of the cyclone drum 11 are fixedly connected and communicated via an integral seal. The top of the cyclone drum 11 is provided with a top plate, the edge of which is fixedly connected to the top edge of the cyclone drum 11 via welded seals. The feed pipe 12 is horizontally disposed and tangentially arranged to the outer edge of the cyclone drum 11, thereby achieving cyclone separation.

[0069] Reference Figures 1 to 3 The discharge pipe 13 is connected to and communicates with the bottom of the cyclone 11 (e.g., via an integral seal or welded seal). A first valve body 131 is installed in the middle of the discharge pipe 13. The feed pipe 12 is connected in series with the first liquid pump and the dilution hopper 19, respectively, via flexible hoses. The first liquid pump is used to press the slurry dilution liquid in the dilution hopper 19 into the cyclone 11. The dilution hopper 19 is in an inverted cone shape, with its bottom higher than the top of the liquid pump and the top of the cyclone 11 to prevent backflow and residue of the dilution liquid.

[0070] Reference Figure 3The dilution funnel 19 is provided with a flushing nozzle 191 that is arranged obliquely upward. The flushing nozzle 191 is plugged into and fixed to the side wall of the dilution funnel 19 (for example, by welding to achieve a sealed and fixed connection). When in use, grab the bottom of the side wall of the concentration pot 21 and turn it over. The concentration pot 21 is obliquely placed on the flushing nozzle 191. Most of the slurry in the concentration pot 21 flows into the dilution funnel 19 when it is turned over; the slurry particles adhering to the inner wall of the concentration pot 21 flow into the dilution funnel 19 under the flushing of the flushing nozzle 191. The minimum diameter of the inner cavity of the concentration pot 21 is larger than the maximum diameter of the flushing nozzle 191, and the diameter difference is not less than 5 mm to avoid slurry splashing during flushing. The flushing nozzle 191 is connected to and communicated with the pure water supply system; a first solenoid valve is provided on the flushing nozzle 191.

[0071] Reference Figure 3 and Figure 5 The side wall of the dilution funnel 19 near the bottom of the flushing nozzle 191 extends upward to form an upper side wall 190, and the upper side wall 190 is in the shape of an arc plate; since the concentration pot 21 is tilted and the opening points to the bottom of the flushing nozzle 191, it is easier for the slurry to splash along the radial direction of the flushing nozzle 191 (because when the slurry particles accumulate at the opening position of the dilution funnel 19, the gap available for liquid flow is reduced, and splashing is likely to occur). The upper side wall 190 is used to divert the slurry splashing obliquely upward back into the dilution funnel 19, so as to avoid the slurry particles from being lost with the splashing slurry, thereby improving the accuracy of subsequent detection.

[0072] Reference Figure 3 and Figure 4A reversible nozzle cleaning assembly 192 is provided above the dilution funnel 19. The nozzle cleaning assembly 192 includes a pad 1921, a flushing ring 1922, a water supply hose 1923, and a reversing motor. One end of the water supply hose 1923 is connected to and communicates with the flushing ring 1922 via a second solenoid valve, and the other end is connected to and communicates with the pure water supply system. The end of the flushing ring 1922 is fixedly connected to an extension rod (e.g., by bolts), which is vertically fixedly connected to the rotating shaft (e.g., by bolts). Two pads 1921 are provided, one on each side of the rotating shaft. The ends of the rotating shaft are respectively inserted into the inner ring positions of the bearings in the mounting holes on the side walls of the pads 1921. The pad 1921 is fixedly connected to the support module 7 via bolts. The reversing motor is fixedly connected to the support module 7 via bolts. The output shaft of the reversing motor is coaxially fixedly connected to the rotating shaft (e.g., by bolts). The reversing motor can drive the flushing ring 1922 to reversal. Before the concentration pot 21 is upside down and mounted on the flushing nozzle 191, the flip motor can drive the flushing ring 1922 to flip outward to provide a storage space for the concentration pot 21; after the concentration pot 21 is removed, the flip motor can drive the flushing ring 1922 to flip until the flushing ring 1922 is directly above the dilution funnel 19, and the second solenoid valve opens to flush away the slurry particles adhered to the inner wall of the dilution funnel 19 and the outer wall of the flushing nozzle 191.

[0073] Reference Figures 3 to 5 The flushing ring 1922 includes a first half-ring 19221 and a second half-ring 19222 fixedly connected and interconnected (e.g., through an integral fixed connection). The first half-ring 19221 and the second half-ring 19222 form a circular ring and are interconnected. An extended flushing rod 19223 is fixedly connected to the middle of the first half-ring 19221. The first half-ring 19221 and the extended flushing rod 19223 are fixedly connected and connected in an ∈ shape (e.g., secured by welding). When the flushing ring 1922 is rotated to be directly above the dilution funnel 19, the extended flushing rod 19223 is directly above the flushing nozzle 191. A first water spray hole defined at the bottom of the extended flushing rod 19223 points toward the flushing nozzle 191. A plurality of first water spray holes are provided and arranged in an array along the length of the extended flushing rod 19223. The extended flushing rod 19223 is straight.

[0074] Reference Figure 5 A notch 1900 is provided on the opposite side of the upper side wall 190 , and the notch 1900 is used to provide an accommodating space for the robot module 6 that clamps the concentration pot 21 .

[0075] Reference Figure 5 and Figure 6The second spray hole on the sidewall of first half-ring 19221 is directed toward the lower-middle portion of upper sidewall 190 for flushing, while the third spray hole on the sidewall of second half-ring 19222 is directed toward the sidewall of dilution funnel 19 below notch 1900, achieving a better flushing effect and avoiding the formation of blind spots. Multiple second spray holes are provided and arranged along the axial direction of first half-ring 19221; multiple third spray holes are provided and arranged along the axial direction of second half-ring 19222.

[0076] Reference Figure 1 and Figure 2 The overflow pipe 14 is N-shaped; one end of the overflow pipe 14 is inserted into the middle of the top plate of the cyclone tube 11, and the other end is inserted into the receiving tube 151 at the top of the connecting tube 15; the top plate and the overflow pipe 14 are sealed and fixedly connected by welding; a ventilation gap is provided between the inner wall of the receiving tube 151 and the outer wall of the overflow pipe 14 to reduce siphoning, thereby preventing relatively large-diameter slurry particles from flowing prematurely and in large quantities through the connecting tube 15 into the filter container 16 due to siphoning. If relatively large-diameter slurry particles flow into the filter container 16 prematurely and in large quantities, they will block the filter holes at the bottom of the filter container 16, causing both coarse and fine particles to accumulate in the filter container 16, reducing the water permeability of the filter container 16 and causing the slurry in the filter container 16 to overflow; the overflow and loss of relatively large-diameter slurry particles will reduce the accuracy of subsequent detection results.

[0077] Reference Figure 2 A vertical support rod 140 is installed on the lower surface of the middle part of the overflow pipe 14, and the top end of the vertical support rod 140 is fixedly connected to the overflow pipe 14 (for example, by bolts or welding); the bottom end of the vertical support rod 140 is fixedly connected to the top plate of the cyclone tube 11 (for example, by bolts or welding), thereby achieving strengthened fixation of the overflow pipe 14, preventing the overflow pipe 14 from hitting the receiving tube 151, and at the same time preventing the connection position between the overflow pipe 14 and the top plate of the cyclone tube 11 from loosening due to shaking caused by water impact, thereby improving the service life of the present invention.

[0078] Reference Figure 1 and Figure 2 The middle portion of connecting tube 15 is spiral-shaped. An inclined guide tube 152 is located at the bottom of connecting tube 15, pointing toward discharge tube 13. Guide tube 152 is L-shaped. The ends of discharge tube 13 and guide tube 152 are both vertically positioned and point toward filter container 16, which is placed on a liftable water collection base 17 and has filter holes on its bottom. The spiral shape in the middle of connecting tube 15 is used to reduce the flow rate of the slurry within connecting tube 15, further reducing the flow rate of the slurry flowing out of discharge tube 13. This prevents slurry splashing in filter container 16 and improves the accuracy of subsequent test results.

[0079] Reference Figure 1 and Figure 2 After the first valve body 131 is closed, conventional cyclone separation operation is carried out. The slurry particles with relatively large diameters accumulate at the bottom of the cyclone cylinder 11, and the slurry particles with relatively small diameters flow into the filter container 16 through the overflow pipe 14 and the connecting pipe 15 to achieve rough separation.

[0080] In the following, the slurry particles with a diameter smaller than the filter hole diameter are referred to as fine particles, and the slurry particles with a diameter larger than the filter hole diameter are referred to as coarse particles; the slurry particle flow with a relatively small diameter is referred to as the first flow, and the slurry particle flow with a relatively large diameter is referred to as the second flow.

[0081] After rough sorting, fine particles are more concentrated in the first material flow, and coarse particles are more concentrated in the second material flow; then the fine particles in the first material flow can pass through the filter holes without the use of external stirring force. In traditional technology, coarse and fine particles are mixed together, and a rotatable stirring claw for providing stirring force needs to be placed in the filter container 16. The filter container 16 is connected to an oscillator. When the filter container 16 oscillates up and down, the stirring fins of the stirring claw collide with the bottom plate or bottom filter screen of the filter container 16, causing grinding of the slurry particles. Some coarse particles are ground into fine particles, which pass through the filter container 16 and are lost, resulting in a decrease in the accuracy of subsequent detection results. The present invention avoids the use of stirring claws, thereby avoiding the occurrence of grinding and further improving detection accuracy.

[0082] Reference Figure 1 and Figure 2 , the first valve body 131 can be opened and closed intermittently so that the direct flushing liquid in the discharge pipe 13 and the overflow flushing liquid in the guide tube 152 can flow out alternately or simultaneously, thereby rinsing the inner cavity of the filter container 16. The flushing liquid is pure water injected into the cyclone 11 through the flushing ring 1922 after rough selection; the flushing liquid includes direct flushing liquid and overflow flushing liquid; the direct flushing liquid is the pure water in the cyclone 11 flowing out through the discharge pipe 13; the overflow flushing liquid is the pure water in the cyclone 11 flowing out through the connecting pipe 15; after the flushing ring 1922 stops injecting water, the first valve body 131 is closed, and the last tube of overflow flushing liquid flows out of the guide tube 152, and then the rinsing is completed. The rinsing operation is a single valve control form controlled by the first valve body 131, and there is no need to introduce additional control structures to avoid increased costs, increased operational complexity and reduced reliability.

[0083] After roughing, the second solenoid valve and first liquid pump are closed, and the first valve body 131 is opened, allowing the second stream to slowly flow through the filter container 16. The pulp particles in the second stream and the coarse particles in the first stream that were retained after roughing accumulate in the filter container 16, forming mixed particles. (During the roughing process, the first stream flowing out of the guide tube 152 exerts an impact force on the filter container 16, causing the retained coarse particles in the first stream to be pushed below the discharge pipe 13, thereby achieving particle mixing.) The first valve body 131 is then closed, and the second solenoid valve and first liquid pump are opened. When the cyclone 11 is filled with pure water, the first valve body 131 is intermittently opened and closed for rinsing.

[0084] When flushing liquid flows alternately from discharge pipe 13 and guide tube 152, slurry particles move left and right within filter container 16, tumbling. When flushing liquid flows simultaneously from discharge pipe 13 and guide tube 152, slurry particles within filter container 16 are dispersed (the sudden increase in flushing liquid flow and impact force, combined with the simultaneous rise in the liquid level within filter container 16, increases the fluidity of the mixed particles and disperses them), thereby rinsing the mixed particles. The present invention utilizes the impact force of the water flow to replace the stirring force of the stirring claws for washing mixed particles, avoiding grinding and achieving higher detection accuracy.

[0085] Reference Figure 1 and Figure 2 The middle portion of the connecting tube 15 is spiral-shaped, which is used to reduce the flow rate of the pure water in the connecting tube 15. During rinsing: if the first valve body 131 is closed, pure water will flow out of the bottom end of the connecting tube 15 after a specific time (this specific time is a fixed value, which can be accurately calculated or roughly obtained through a limited number of experiments); if the first valve body 131 is opened, pure water will immediately flow out of the discharge pipe 13. Therefore, by controlling the time interval and the duration of each opening of the first valve body 131, the flushing liquid can be controlled to flow out alternately or simultaneously from the discharge pipe 13 and the guide tube 152, thereby meeting the rinsing requirements.

[0086] Reference Figure 1 、 Figure 2 、 Figure 7 and Figure 8 The cyclone tube 11 and the connecting tube 15 are both upright; the feed tube 12 and the receiving tube 151 are fixedly connected in a cross shape (for example, fixedly connected by a clamp or fixedly connected by welding); the outer wall of the filter container 16 is provided with a horizontal grasping handle 161 (for example, fixedly connected by integral molding); the grasping handle 161 is used for grasping by the clamping claw in the manipulator module 6.

[0087] Reference Figure 8 and Figure 9The bottom end of the discharge pipe 13 has a rectangular cross-section, and the bottom end of the guide tube 152 has a rectangular cross-section. The cross-section of the filter container 16 is rectangular and fits perfectly with the bottom ends of the discharge pipe 13 and the guide tube 152. Avoid excessive gaps between the filter container 16, the discharge pipe 13, and the guide tube 152 to further prevent slurry splashing. The gaps between the filter container 16, the discharge pipe 13, and the guide tube 152 are all set to within 5 mm.

[0103] The slurry fineness detection method uses slurry fineness detection equipment to detect the slurry fineness, and the steps include:

[0104] S1. Place the concentration pot 21 on the lifting receiving plate 23, use a sampling tube to extract the slurry sample on site and inject it into the sampling funnel 22.

[0105] S2. The lifting base 24 pushes the concentration pot 21 upward, so that the concentration pot 21 is close to the sampling funnel 22; the second valve body 221 is opened for a limited time, and the sampling funnel 22 injects the slurry sample into the concentration pot 21; after the overflow is quantitative, the slurry sample in the concentration pot 21 is the slurry concentrate.

[0106] S3, the manipulator module 6 grabs the concentration pot 21 and places the concentration pot 21 on the first weighing module 3, and records the total weight of the concentration pot 21 and the slurry as m1;

[0107] S4. The manipulator module 6 grabs the concentration pot 21 and pours the slurry concentrate in the concentration pot 21 into the dilution funnel 19, which is then inverted onto the flushing nozzle 191. The flushing nozzle 191 flushes out the slurry particles adhering to the inner wall of the concentration pot 21 to obtain a slurry dilution liquid. The first liquid pump presses the slurry dilution liquid into the cyclone 11. The slurry particles with relatively large diameters accumulate at the bottom of the cyclone 11, while the slurry particles with relatively small diameters flow into the filter container 16 through the overflow pipe 14 and the connecting pipe 15. The slurry dilution liquid has higher fluidity and a larger volume than the slurry concentrate, so it can be gradually and slowly injected into the cyclone 11 for sorting. By controlling the dilution ratio, the working efficiency of the cyclone 11 can be adapted, avoiding the problem that the power of the hydrocyclone separator 1 cannot adapt to the concentration of the slurry concentrate, resulting in poor sorting effect. It further avoids the problem that the filter holes are blocked, resulting in slurry overflow in the filter container 16, thereby improving detection accuracy.

[0108] S5. Open the first valve body 131, and the slurry particles with relatively large diameters flow into the filter container 16; the first valve body 131 is intermittently opened and closed to flush the filter container 16, and the oversize material is obtained.

[0109] S6, the water collecting base 17 drives the filter container 16 to move downward, the manipulator module 6 grabs the filter container 16, and turns the filter container 16 upside down in the recovery funnel 41; then the first lifting component 42 drives the recovery funnel 41 and the filter container 16 to move upward until the filter container 16 is placed in the inner cavity of the splash shield 43; the spray ring 432 is started, and the screened material is flushed into the recovery funnel 41; the spray ring 432 is closed, and the first lifting component 42 drives the recovery funnel 41 and the filter container 16 to move downward; the screened material in the recovery funnel 41 is allowed to settle.

[0110] S7 , the manipulator module 6 grasps the concentration pot 21 and places the concentration pot 21 directly below the recovery funnel 41 ; opens the third valve body 411 , and the overscreen flows into the concentration pot 21 ; then closes the third valve body 411 .

[0111] S8. The manipulator module 6 places the concentration pot 21 on the second weighing module 5 and allows it to stand to obtain a large-particle ore slurry with the same volume as the original ore slurry. The total weight of the concentration pot 21 and the large-particle ore slurry is recorded as m3.

[0112] During steps S6 to S8, while the manipulator module 6 is gripping the concentration pot 21, the non-slip pad on the gripping claws seals the overflow hole 211. (When overflow hole 211 is exposed, the slurry will overflow; the inevitable vibrations generated during operation by the manipulator module 6 can cause excessive slurry outflow, reducing the slurry's weight and volume and lowering detection accuracy.) At this point, the slurry level is higher than the overflow hole 211. The concentration pot 21 is then placed on the second weighing module 5, allowing excess slurry to overflow, achieving equal-volume sampling. An air gun is installed on the manipulator module 6 or support module 7 to blow away any water droplets adhering to the outer wall of the concentration pot 21 during slurry overflow, thereby ensuring weight accuracy.

[0113] During steps S6 to S8, by setting the position of the overflow port of the recovery funnel 41, the total volume of the material discharged from the recovery funnel 41 in a single time can be slightly smaller than the volume of the concentration pot 21; then the spray ring 432 is started again to flush the inner wall of the recovery funnel 41 to ensure that the slurry particles are completely collected. After standing for a period of time, the slurry particles obtained from the second flushing and part of the water are injected into the concentration pot 21 through the recovery funnel 41.

Retrieve and query Table 1 to obtain the concentration c1 of the ore pulp stock solution corresponding to the weight m2 of the ore pulp stock solution: compare the value of m2 with the ore pulp weight data in the concentration measurement table one by one, and take the ore pulp percentage mass concentration value corresponding to the ore pulp weight value that is closest (for example, the absolute value of the difference is the smallest) * 100% as the data for c1.

[0128] S99. The fineness of the slurry concentrate is equal to the fineness of the slurry sample.

[0129] In this embodiment, the mass m of the concentration pot 21 is 196 g; the volume of the concentration pot 21 is 513 ml; and the specific gravity ρ3 of the ore is 3.88 g / cm3.

[0130] The following provides the derivation process of the calculation formula for the concentration c2 of the large particle ore slurry in step S96:

[0131] Given: ore specific gravity ρ3, water density ρwater (taken as 1 gram per milliliter), mass m of concentration pot 21, volume v of concentration pot 21 = total volume vtotal of large particle ore slurry; the density ρ2 of large particle ore slurry is obtained from the above calculation,

[0132] Formula ①: The total mass of large particle slurry mtotal = ρ2*vtotal;

[0133] Formula ②: mtotal = m5 + mwater, where m5 is the mass of the oversize material and mwater is the mass of the water in the large particle ore slurry;

[0134] Formula ③: m5=ρ3*vstone=ρ3*(vtotal-vwater), where vstone is the volume of the material on the sieve;

[0135] Formula ④: mwater = vwater * ρwater = vwater;

[0136] From formulas ① to ④, we can get:

[0137] ρ2*vtotal=mtotal=m5+mwater=ρ3*(vtotal-vwater)+vwater=ρ3*vtotal-ρ3*vwater+vwater;

[0138] Therefore, ρ2*vtotal-ρ3*vtotal=vwater-ρ3*vwater;

[0139] Therefore, we get formula ⑤:

[0140] ;

[0141] From formulas ④ to ⑤, we can get:

[0142] .

[0143] In the present invention, controlling the time interval of opening of the first valve body 131 and the duration of each opening can control the flushing liquid to flow out alternately or simultaneously from the discharge pipe 13 and the guide cylinder 152, as described in detail below:

[0144] After closing the first valve body 131, the flushing liquid flows sequentially through "the starting end of the overflow pipe 14, the end of the overflow pipe 14, the starting end of the receiving tube 151, the end of the receiving tube 151, the spiral portion in the middle of the connecting pipe 15, the starting end of the guide tube 152, and the end of the guide tube 152." Assume that closing the first valve body 131 can generate an overflow flow composed of flushing liquid. The time required for the front of the overflow flow to flow from the starting end of the overflow pipe 14 to the end of the overflow pipe 14 is 1 second, and the time required for the front of the overflow flow to flow from the end of the overflow pipe 14 to the end of the guide tube 152 is 4 seconds. Similarly, the time required for the tail of the overflow flow to flow from the starting end of the overflow pipe 14 to the end of the overflow pipe 14 is 1 second, and the time required for the tail of the overflow flow to flow from the end of the overflow pipe 14 to the end of the guide tube 152 is 4 seconds.

[0145] Reference Figure 20 Assuming that the time interval for opening the first valve body 131 is 5 seconds and the duration of each opening is 5 seconds, then taking the starting time of closing the first valve body 131 as the reference time point, the overflow flow appears at the end of the overflow pipe 14 after a delay of 1 second and the overflow flow lasts for 5 seconds, and the overflow flow appears at the end of the overflow pipe 14 after a delay of 5 seconds and the overflow flow lasts for 5 seconds. After the first valve body 131 is opened, the flushing liquid flow immediately appears at the end of the discharge pipe 13 and the flushing liquid flow lasts for 5 seconds. Therefore, the technical purpose of the flushing liquid flowing out of the discharge pipe 13 and the guide tube 152 at the same time is achieved within the actual time period of 5 to 10 seconds, 15 to 20 seconds.....

[0146] Reference Figure 21 Assuming that the time interval for opening the first valve body 131 is 2.5 seconds and the duration of each opening is 2.5 seconds, then taking the starting time of closing the first valve body 131 as the reference time point, the overflow flow appears at the end of the overflow pipe 14 after a delay of 1 second and the overflow flow lasts for 2.5 seconds, the overflow flow appears at the end of the overflow pipe 14 after a delay of 5 seconds and the overflow flow lasts for 2.5 seconds, and after the first valve body 131 is opened, the flushing liquid flow immediately appears at the end of the discharge pipe 13 and the flushing liquid flow lasts for 2.5 seconds. Therefore, the technical purpose of alternately discharging flushing liquid from the discharge pipe 13 and the guide tube 152 is achieved within the actual time period of 2.5 to 7.5 seconds, 7.5 to 12.5 seconds.....

[0147] The time required for the front / tail of the overflow flow to flow from the end of the overflow pipe 14 to the end of the guide tube 152 is related to the pipe diameter, the number of spiral turns, and the spiral diameter of the middle part of the connecting pipe 15. Therefore, using connecting pipes 15 of different specifications can control the length of this time, thereby adapting the opening interval and the duration of each opening of the first valve body 131, and further adapting to the detection requirements of slurry samples of different specifications (slurries of different specifications have different sedimentation rates, and different rinsing impact frequencies are required to adapt to the sedimentation rate).

[0148] Each opening and closing of the first valve body 131 causes wear on the internal structure, so the service life of the first valve body 131 is usually expressed in the form of the total number of openings and closings. Under the premise of adapting to the slurry settling rate, the rinsing impact frequency is reduced as much as possible, thereby reducing the opening and closing frequency requirement of the first valve body 131, which can enable the first valve body 131 to be used for a longer time.

[0149] The connecting pipe 15 includes a receiving tube 151 and a flow guide tube 152 at both ends, so the end of the connecting pipe 15 is the end of the flow guide tube 152 .

[0150] When the first valve body 131 is opened, the flow rate of the flushing liquid at the position of the discharge pipe 13 is equal to the flow rate of the flushing liquid at the position of the feed pipe 12 (achieved by selecting a discharge pipe 13 with an appropriate diameter and adapting the opening degree of the first valve body 131) to ensure that overflow does not occur at this time, and the liquid level of the flushing liquid in the cyclone 11 remains basically stable and does not drop significantly.

[0151] In the present invention, the first valve body 131, the second valve body 221, and the third valve body 411 are all electrically controlled pneumatic on / off angle valves; the first linear actuator, the second linear actuator, and the third linear actuator are all electric push rods, pneumatic push rods, hydraulic push rods, or a combination thereof (e.g., electro-hydraulic push rods). The first valve body 131, the second valve body 221, the third valve body 411, the first solenoid valve, the second solenoid valve, the third solenoid valve, the fourth solenoid valve, the fifth solenoid valve, the first linear actuator, the second linear actuator, and the third linear actuator, and other electrically controlled components are connected to an external power supply and a computer via an electrical cabinet. The computer controls the activation and deactivation of each of the electrically controlled components of the present invention through the electrical cabinet.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction.
