Description

Technical Field

[0001] This utility model relates to the field of pneumatic conveying technology, and in particular to a pulse-type pneumatic conveying device with intelligent temperature control and pressure balance. Background Technology

[0002] Pneumatic conveying technology, which utilizes airflow energy to achieve efficient material transport, is widely used in various industries such as food processing, pharmaceutical production, chemicals, and building materials. Currently, most mainstream pneumatic conveying devices on the market are based on continuous air supply, using a stable airflow generated by a fan to propel materials along the conveying pipe, ultimately achieving material collection and recovery.

[0003] During pneumatic conveying, the temperature inside the conveying pipeline may rise due to friction between compressed air and materials, as well as the influence of ambient temperature. This can lead to changes in material properties or reduced conveying efficiency. Furthermore, the pressure inside the pipeline will constantly change. If the pressure cannot be adjusted in a timely and effective manner, it may cause system instability, or even blockage or equipment damage. Utility Model Content

[0004] In the existing technology, due to the friction between compressed air and materials and the influence of ambient temperature, the temperature inside the conveying pipeline may rise, leading to changes in material properties or a reduction in conveying efficiency. Furthermore, the pressure inside the pipeline will constantly change. If the pressure cannot be adjusted in a timely and effective manner, it may lead to unstable system operation, or even blockage or equipment damage. This utility model provides a pulse-type pneumatic conveying device with intelligent temperature control and pressure balance.

[0005] The technical solution adopted in this utility model is: an intelligent temperature control and pressure balance pulse pneumatic conveying device, including a storage tank, a conveying pipe, and a recovery bin. A discharge pipe is fixedly installed at the bottom of the storage tank, and the end of the discharge pipe is vertically fixed to the top of the straight end of the conveying pipe. A discharge valve is fixedly installed on the surface of the discharge pipe. The end of the conveying pipe is fixedly installed above the recovery bin. A Roots blower is installed at the initial end of the conveying pipe. The conveying pipe is connected to the air outlet of the Roots blower through a main air pipe. A temperature control component is fixedly installed on the surface of the conveying pipe. The temperature control component includes a jacket. Pressure regulating components are installed on the surfaces of the storage tank and the conveying pipe to facilitate pressure balance control. The temperature control component can adjust the conveying temperature for different materials to avoid material deterioration or caking due to abnormal temperature. The pressure regulating component avoids the risk of pressure imbalance in advance and prevents material leakage and conveying interruption due to excessive pressure difference.

[0006] Furthermore, the jacket is disposed at the straight end of the conveying pipe and is tightly fitted to the outer wall of the conveying pipe, forming a closed heat exchange cavity between the jacket and the outer wall of the conveying pipe. An inlet is fixedly installed on the upper side of one side of the jacket, and an outlet is fixedly installed on the lower side of the other side of the jacket. The jacket is tightly fitted to the outer wall of the conveying pipe and forms a closed heat exchange cavity, maximizing the contact area and ensuring the heat exchange efficiency between the heat exchange medium and the conveying pipe.

[0007] Furthermore, the straight end of the conveying pipe is equipped with two temperature sensors. One temperature sensor is fixedly installed on the side close to the Roots blower, and the other temperature sensor is fixedly installed on the side away from the Roots blower. These sensors monitor the initial airflow temperature close to the Roots blower and the material conveying temperature away from the Roots blower, respectively, accurately capturing the temperature change of the airflow from its generation to its mixing with the material.

[0008] Furthermore, the pressure regulating component includes an electric pressure regulating valve, which is fixedly installed on the surface of the straight end of the conveying pipe near the Roots blower. A first pressure sensor is also fixedly installed on the side of the conveying pipe near the Roots blower. The first pressure sensor captures the pressure change of the conveying pipe near the blower end in real time. When the pressure is too high, the electric pressure regulating valve automatically releases pressure to avoid high pressure damaging the conveying pipe or causing the material flow rate to be too fast and wear the pipe wall. When the pressure is too low, the valve can be closed to cooperate with the blower to increase the air supply intensity and quickly replenish the pressure.

[0009] Furthermore, the pressure regulating component also includes a breather valve, which is fixedly installed at the top center of the storage tank. A second pressure sensor is also fixedly installed on one side of the top of the storage tank. The breather valve can automatically open according to the pressure inside the tank, avoiding the lag of manual pressure adjustment and preventing the storage tank from deforming or cracking due to abnormal pressure. The second pressure sensor monitors the pressure inside the tank in real time, providing accurate information for the action of the breather valve and ensuring stable pressure inside the tank during material filling.

[0010] Furthermore, a dust collector is fixedly installed on the top of the recycling bin. The dust collector is a bag filter, which can efficiently filter dust particles in the conveying airflow to prevent dust from being emitted with the exhaust gas and polluting the environment.

[0011] Furthermore, a feed inlet is fixedly installed on the top of the storage tank, and a sealing plug is fitted over the feed inlet. The feed inlet facilitates rapid filling of materials, and the fitting design of the sealing plug can achieve complete sealing of the feed inlet after filling, preventing external dust and impurities from entering the storage tank and contaminating the materials.

[0012] The beneficial effects of this utility model are:

[0013] 1. This utility model can adjust the conveying temperature for different materials through a temperature control component, so as to avoid the materials from deteriorating or clumping due to abnormal temperature; it solves the problem that the temperature in the conveying pipeline may rise due to friction between compressed air and materials and the influence of ambient temperature during pneumatic conveying, which may lead to changes in material properties or reduced conveying efficiency.

[0014] 2. This utility model avoids the risk of pressure imbalance in advance by using a pressure regulating component, preventing material leakage and conveying interruption caused by excessive pressure difference. It solves the problem that the pressure in the pipeline will change continuously during the conveying process. If the pressure cannot be adjusted in time and effectively, it may lead to unstable system operation or even blockage or equipment damage. Attached Figure Description

[0021] The following is in conjunction with the appendix Figures 1-3 The present invention will be further described below.

[0022] To address the problems existing in the background technology, this application proposes the following technical solution: a pulse-type pneumatic conveying device with intelligent temperature control and pressure balance.

[0023] The specific technical solution includes a storage tank 1, a conveying pipe 2, and a recovery bin 3. A discharge pipe 4 is fixedly installed at the bottom of the storage tank 1, and the end of the discharge pipe 4 is vertically fixed to the top of the straight end of the conveying pipe 2. A discharge valve 5 is fixedly installed on the surface of the discharge pipe 4. The end of the conveying pipe 2 is fixedly installed above the recovery bin 3. A Roots blower 6 is installed at the initial end of the conveying pipe 2. The conveying pipe 2 is connected to the air outlet of the Roots blower 6 through a main air pipe. A temperature control component 7 is fixedly installed on the surface of the conveying pipe 2. The temperature control component 7 includes a jacket 701. Pressure regulating components 8 are installed on the surfaces of the storage tank 1 and the conveying pipe 2 to facilitate pressure balance control. The temperature control component 7 on the surface of the conveying pipe 2 can adjust the conveying temperature for different materials to avoid material deterioration or caking due to abnormal temperature. The pressure regulating components 8 of the storage tank 1 and the conveying pipe 2 can avoid the risk of pressure imbalance in advance and prevent material leakage and conveying interruption due to excessive pressure difference.

[0024] Reference Figure 1 and Figure 3 As shown, the jacket 701 is set at the straight end of the conveying pipe 2 and is tightly fitted to the outer wall of the conveying pipe 2. A closed heat exchange cavity is formed between the jacket 701 and the outer wall of the conveying pipe 2. An inlet 702 is fixedly installed on the upper side of one side of the jacket 701, and an outlet 703 is fixedly installed on the lower side of the other side of the jacket 701. Two temperature sensors 704 are provided at the straight end of the conveying pipe 2. One temperature sensor 704 is fixedly installed on the side close to the Roots blower 6, and the other temperature sensor 704 is fixedly installed on the side away from the Roots blower 6. The two temperature sensors 704 on the conveying pipe 2 collect the airflow temperature and the temperature after the airflow and material are mixed in real time. The jacket 701 is tightly fitted to the outer wall of the conveying pipe 2 to form a closed heat exchange cavity. When the temperature is too high, cooling medium is introduced through the inlet 702 on one side of the jacket 701. The cooling medium flows in the heat exchange chamber and exchanges heat with the outer wall of the conveying pipe 2 to reduce the temperature inside the pipe. After heat exchange, the medium is discharged from the outlet 703 on the other side of the jacket 701. When the temperature is too low, heating medium is introduced through the inlet 702 to raise the temperature inside the pipe and ensure that the material is conveyed at a suitable temperature. Both temperature sensors are model TMP1827.

[0025] Reference Figure 1 and Figure 2As shown, the pressure regulating assembly 8 includes an electric pressure regulating valve 801, which is fixedly installed on the surface of the straight end of the conveying pipe 2 near the Roots blower 6. A first pressure sensor 802 is also fixedly installed on the side of the conveying pipe 2 near the Roots blower 6. The pressure regulating assembly 8 also includes a breather valve 803, which is fixedly installed at the top center of the storage tank 1. A second pressure sensor 804 is also fixedly installed on one side of the top of the storage tank 1. The first pressure sensor 802 on the side of the conveying pipe 2 near the Roots blower 6 monitors the airflow pressure in the pipe in real time. When the pressure is too high, the electric pressure regulating valve 801 of the pressure regulating assembly 8 automatically opens to release pressure; when the pressure is too low, the electric pressure regulating valve 801 closes, and the Roots blower 6 increases the pulse air supply intensity to ensure stable pressure in the conveying pipe 2. When material falls from the storage tank 1 into the conveying pipe 2, the pressure inside the tank will change. When the pressure inside the tank is too low and forms a negative pressure, the breather valve 803 on the top of the storage tank 1 automatically opens to introduce outside air to balance the pressure; when the pressure is too high, the breather valve 803 opens to release pressure. Combined with real-time monitoring by the second pressure sensor 804, this ensures that the pressure of the storage tank 1 and the conveying pipe 2 is matched, preventing interruption or leakage of material conveying. Both the first and second pressure sensors are model BSP00YC.

[0026] Reference Figure 1 and Figure 2 As shown, a dust collector 9 is fixedly installed on the top of the recycling bin 3. The dust collector 9 is a bag filter. An inlet 10 is fixedly installed on the top of the storage tank 1. A sealing plug 11 is fitted above the inlet 10. When the dust collector 9 on the top of the recycling bin 3 is activated, the dust particles in the airflow are filtered and trapped by the filter bag. The purified air is discharged to ensure the purity of the recycled material and avoid dust pollution of the environment. The sealing plug 11 ensures that the storage tank 1 is in a sealed state to prevent air leakage or material spillage during subsequent transportation.

[0027] To ensure that those skilled in the art can fully understand the technical solution, this application provides the following overall overview:

[0028] First, remove the sealing plug 11 from the top inlet 10 of storage tank 1, inject the material to be conveyed into storage tank 1, and then re-tighten the sealing plug 11 to ensure that storage tank 1 is sealed. Start the Roots blower 6 and intermittently pulse high-pressure airflow through the main air pipe to the conveying pipe 2, forming an airflow channel towards the recovery bin 3. When the pressure in the conveying pipe 2 reaches the standard, open the discharge valve 5 on the discharge pipe 4 at the bottom of storage tank 1. Under the action of gravity and negative airflow pressure, the material enters the conveying pipe 2 along the discharge pipe 4, forming a gas-solid two-phase flow with the airflow. If the temperature sensor 704 detects an abnormal temperature, it adjusts the temperature through the jacket 701 of the temperature control component 7: when the temperature is too high, the water inlet... Cooling medium is introduced into 702, and after being cooled by the heat exchange chamber, it is discharged from the outlet 703. When the temperature is too low, heating medium is introduced into the inlet 702 to raise the temperature. The first pressure sensor 802 monitors the pressure. If it is too high, the electric pressure regulating valve 801 is opened to release the pressure. If it is too low, the valve is closed and the air supply intensity of the Roots blower 6 is increased. The second pressure sensor 804 monitors the pressure. If there is an abnormality, air is introduced or pressure is released through the breather valve 803 to maintain the pressure stability in the storage tank 1. The gas-solid two-phase flow enters the recovery bin 3 along the conveying pipe 2. The material falls into the bottom of the recovery bin 3 for storage due to gravity. The airflow flows upward. The dust removal device 9 at the top of the recovery bin 3 is activated to filter the dust in the airflow. The purified air is discharged.
