Description

Technical Field

[0001] This utility model relates to a dust removal system for a cone crusher station with a pressure regulating block assembly, and belongs to the technical field of cone crusher stations. Background Technology

[0002] A cone crusher is a type of medium and fine crusher, an essential part of a crushing production line, and is widely used in industries such as metal mining and sand and gravel aggregates. However, due to the harsh working environment and the large amount of dust inside the main unit, the lubricating oil becomes less clean after a certain period of use, which can cause wear and even damage to the lubrication pump and internal components of the main unit. Therefore, it is necessary to add a dust removal system to reduce the contamination of the lubricating oil by dust.

[0003] The existing technical solution is as follows: a vortex air pump generates positive pressure air, which is blown into the lubrication chamber of the main unit through the air intake pipe, so that the inside of the sealing ring (lubrication chamber) maintains a certain air pressure, thereby preventing dust from the outside of the sealing ring (crushing chamber) from entering the sealing ring and ensuring the cleanliness of the lubricating oil.

[0004] The problem with existing technology is that during use, it mainly relies on the internal air pressure adjustment of the lubrication chamber, which cannot create a suitable airflow pressure for the dust in the crushing chamber. If the air pressure is too low, it cannot break through the sealing ring to form positive pressure in the crushing chamber, causing dust to enter the lubrication chamber and contaminate the lubricating oil; if the air pressure is too high, it will cause oil loss in the lubrication chamber (the lubricating oil is thrown out of the lubrication chamber under the action of centrifugal force and air pressure). Summary of the Invention

[0005] To address the shortcomings of existing technologies, this utility model provides a dust removal system for a cone crusher station with a pressure regulating block assembly. This system can dynamically fine-tune the lubrication chamber pressure based on the apparent value of the pressure gauge, preventing the lubrication chamber pressure from being too high or too low, which could lead to corresponding problems.

[0006] This utility model is achieved according to the following technical solution:

[0007] In a first aspect, this utility model provides a dust removal system for a cone crusher station with a pressure regulating block assembly, comprising:

[0010] An intake pipe connects the power source component and the lubrication chamber. Positive pressure gas generated by the power source component is blown into the lubrication chamber through the intake pipe and discharged from the sealing assembly, forming positive pressure in the lubrication chamber.

[0011] The pressure regulating block assembly is connected in series in the air intake pipe to regulate the airflow pressure entering the lubrication chamber, so that the air pressure inside the lubrication chamber is always kept within a preset range.

[0020] In some embodiments, the adjustable component includes:

[0021] A quick-adjustment component is installed on the pressure regulating block and connected to the air pressure chamber of the pressure regulating block, used to adjust the air pressure value inside the pressure regulating block by a large range;

[0022] A micro-adjustment component is installed on the pressure regulating block and connected to the air pressure chamber of the pressure regulating block, and is used to adjust the air pressure value inside the pressure regulating block by a small amplitude.

[0023] In some embodiments, the quick-adjustment component consists of at least one plug threaded onto the pressure regulating block, and the internal air pressure of the pressure regulating block is adjusted by removing and installing the plug.

[0024] In some embodiments, the micro-adjustment component consists of at least one screw threaded onto the pressure regulating block, and the internal air pressure of the pressure regulating block is adjusted by removing and installing the screw.

[0025] Secondly, this utility model provides a cone crushing station, including the aforementioned cone crushing station dust removal system with pressure regulating block assembly.

[0026] The beneficial effects of this utility model are:

[0027] The pressure regulating block assembly in this invention has a simple structure.

A crushing chamber 7 is provided outside the rotating component, and a lubrication chamber 8 is provided inside the rotating component. The crushing chamber 7 and the lubrication chamber 8 are isolated and sealed by a sealing assembly. The power source component is used to output gas to the outside. The air inlet pipe connects the power source component and the lubrication chamber 8. The positive pressure gas generated by the power source component is blown into the lubrication chamber 8 through the air inlet pipe and discharged from the sealing assembly, forming a positive pressure in the lubrication chamber 8. The pressure regulating block assembly 6 is connected in series in the air inlet pipe to regulate the airflow pressure entering the lubrication chamber 8, so that the air pressure value inside the lubrication chamber 8 is always maintained within a preset range.

[0040] It should be noted that the power source component uses a vortex air pump 5, and the sealing assembly consists of a T-type seal 2 and a U-type seal.

[0041] The following is a further explanation of the voltage regulating block assembly described above.

[0042] like Figure 3 , Figure 4As shown, the pressure regulating block group 6 includes a pressure regulating block 6.1, a pressure detection component, and at least one adjustable component; the pressure regulating block 6.1 has at least one air inlet and at least one air outlet; the pressure detection component is installed on the pressure regulating block 6.1 and is used to detect the air pressure value inside the pressure regulating block 6.1 and to display the detected air pressure value in real time; at least one adjustable component is installed on the pressure regulating block 6.1 and is used to adjust the air pressure value inside the pressure regulating block 6.1.

[0043] Further plans will continue to be considered. Figure 3 , Figure 4 As shown, the pressure detection component is a wind pressure gauge 6.2, whose interface is fixed on the pressure regulating block 6.1 and connected to the air pressure chamber of the pressure regulating block 6.1.

[0044] Further plans will continue to be considered. Figure 3 , Figure 4 As shown, the pressure regulating block 6.1 has a rotary joint 6.5 with internal threads at both the air inlet and outlet.

[0045] The preferred solution will continue to be referenced. Figure 3 , Figure 4 As shown, the pressure regulating block 6.1 is provided with an air inlet and an air outlet. The rotary joint 6.5 at the air inlet is screwed onto the air outlet of the vortex air pump 5, and the rotary joint 6.5 at the air outlet is screwed onto the air inlet of the air inlet pipe.

[0046] Further plans will continue to be considered. Figure 3 , Figure 4 As shown, the outer circumferential surface of the rotary joint 6.5 is designed with an external hexagonal or external quadrangular structure, which makes it easy to rotate the rotary joint 6.5 with a wrench.

[0047] The adjustable components described above will be further explained below.

[0048] like Figure 3 , Figure 4 As shown, the adjustable component includes a rapid adjustment component and a fine adjustment component; the rapid adjustment component is installed on the pressure regulating block 6.1 and is connected to the air pressure chamber of the pressure regulating block 6.1, and is used to adjust the air pressure value inside the pressure regulating block 6.1 by a large amplitude; the fine adjustment component is installed on the pressure regulating block 6.1 and is connected to the air pressure chamber of the pressure regulating block 6.1, and is used to adjust the air pressure value inside the pressure regulating block 6.1 by a small amplitude.

[0049] Further plans will continue to be considered. Figure 3 , Figure 4 As shown, the quick-adjustment component consists of at least one plug 6.4, which is threaded onto the pressure regulating block 6.1. The internal air pressure of the pressure regulating block 6.1 is adjusted by removing and installing the plug 6.4.

[0050] In a preferred embodiment, as shown in the attached diagram, the quick-adjustment component consists of two plugs 6.4. The internal air pressure of the pressure regulating block 6.1 is adjusted by removing or installing one or both plugs 6.4. Of course, the quick-adjustment component is not limited to the two mentioned above; in actual designs, it can also be designed with three or four plugs.

[0051] Further plans will continue to be considered. Figure 3 , Figure 4 As shown, the micro-adjustment component consists of at least one screw 6.3, which is threaded onto the pressure regulating block 6.1. The internal air pressure of the pressure regulating block 6.1 is adjusted by removing and installing the screw 6.3.

Of course, the micro-adjustment component is not limited to the aforementioned ten; in practical designs, it can be designed to have more than ten.

[0053] The following describes the working process of the dust removal system of the cone crusher station with pressure regulating blocks.

[0054] like Figure 1 , Figure 2 As shown, when the dust removal system is working, the vortex air pump 5 generates positive pressure air, which is blown towards the main unit through the air intake pipe. The airflow enters through the lubrication chamber inlet of the main unit, passes through a series of channels in the eccentric assembly 3, and exits from the T-type seal 2 and U-type seal 4, forming positive pressure in the lubrication chamber 8 to prevent dust from entering the crushing chamber 7, ensuring the cleanliness of the lubricating oil and extending the service life of the main unit. Figure 3 , Figure 4 As shown, the pressure regulating block group 6 is installed and fixed at the air outlet of the vortex air pump 5 by a rotary joint 6.5 on one side. The air pressure is displayed in real time by the air pressure gauge 6.2. When the air pressure is high, a certain number of screws 6.3 or plugs 6.4 are unscrewed according to the air pressure range. When the air pressure is low, a certain number of screws 6.3 or plugs 6.4 are tightened according to the air pressure range, thereby realizing the pressure regulating process.

[0055] In summary, the pressure regulating block assembly in this utility model has a simple structure. The number of plugs and screws on the pressure regulating block assembly is adjusted by changing the reading of the air pressure gauge to change the air pressure inside the main unit. This ensures that the lubricating oil is not contaminated or lost at the lowest cost, thus extending the service life of the main unit.
