[0002] Certain waste materials need to be cooled during transportation to meet subsequent discharge or other needs. Take oilfield oily sludge as an example. Oilfield oily sludge belongs to the national hazardous waste list HW08. Oily sludge is usually treated based on pyrolysis, and pyrolysis of oily sludge often requires high temperatures above 500°C. The dry residue after pyrolysis is still in a high temperature state.

[0003] For the cooling of high-temperature dry slag, the relevant technologies usually adopt centralized cooling or spray cooling. Among them, centralized cooling requires the high-temperature dry slag to be transported to a designated area through a conveying device. The high temperature of the dry slag can easily affect the normal operation of the conveying device and even cause safety accidents; while spray cooling during the dry slag transportation process will generate a large amount of water vapor and affect the normal operation of the conveying device.

[0004] In summary, in the related art, waste such as dry slag in a high temperature state will affect the normal operation of the transmission device. Utility Model Content

[0005] The utility model aims to provide a cooling conveying device to solve the problems of low transmission efficiency and poor cooling effect of high-temperature dry slag conveying devices in related technologies.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A cooling and conveying device comprises: a spiral conveying device, comprising a barrel, a screw and a motor, the motor is connected to the screw, the screw is arranged in a material cavity of the barrel and can rotate in the barrel; a cooling channel is arranged on the screw along the conveying direction of the waste material; a feed port and a discharge port are arranged in sequence in the barrel along the conveying direction, and the feed port and the discharge port are both connected to the material cavity of the barrel; a heat exchanger and a liquid storage tank for storing coolant, the cooling channel, the heat exchanger and the liquid storage tank are connected end to end; a pump body, the cooling channel is connected to the liquid storage tank through the pump body, or the cooling channel is connected to the heat exchanger through the pump body.

[0008] Optionally, the barrel has an inner wall and an outer wall, a cooling cavity is formed between the inner wall and the outer wall, and the cooling cavity, the heat exchanger and the liquid storage tank are connected end to end.

[0009] Optionally, it also includes: a first control valve arranged between the spiral conveyor and the liquid storage tank, through which the coolant can enter the cooling channel, and / or a second control valve arranged between the spiral conveyor and the liquid storage tank, through which the coolant can enter the cooling chamber.

[0010] Optionally, it also includes: a first one-way valve arranged between the spiral conveying device and the heat exchanger, through which the coolant in the cooling channel can enter the heat exchanger, and / or a second one-way valve arranged between the spiral conveying device and the heat exchanger, through which the coolant in the cooling cavity can enter the heat exchanger.

[0011] Optionally, the height of the spiral conveyor, the height of the heat exchanger and the height of the pump body are all greater than the height of the liquid storage tank, and the direction of the height is the direction of gravity.

[0012] Optionally, the height of the location where the inlet of the cooling channel is located is less than the height of the location where the outlet of the cooling channel is located, and the height direction is the gravity direction.

[0013] Optionally, the screw includes a rotating shaft and a spiral blade arranged on the rotating shaft, the cooling channel is arranged on the rotating shaft, the motor is connected to the rotating shaft, and a scraper is arranged on the outer edge of the spiral blade close to the barrel.

[0014] Optionally, a plurality of knives are arranged along the spiral extension direction of the spiral blade.

[0015] Optionally, both ends of the screw extend out of the barrel so that the cooling channel is connected to the heat exchanger and the liquid storage tank respectively.

[0016] Optionally, the feed port of the barrel is arranged close to the liquid storage tank, and the discharge port of the barrel is arranged close to the heat exchanger.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0018] The cooling and conveying device disclosed in the present application includes: a spiral conveying device, including a barrel, a screw and a motor, the motor is connected to the screw, the screw is arranged in the material cavity of the barrel, and can rotate in the barrel; a cooling channel is arranged through the screw along the transmission direction of the waste material; a feed port and a discharge port are arranged in sequence in the barrel along the transmission direction, and the feed port and the discharge port are both connected to the material cavity of the barrel; a heat exchanger and a liquid storage tank for storing coolant, the cooling channel, the heat exchanger and the liquid storage tank are connected end to end; a pump body, the cooling channel is connected to the liquid storage tank through the pump body, or the cooling channel is connected to the heat exchanger through the pump body.

[0019] In this way, after the high-temperature waste enters the barrel from the feed port, the coolant can cool the waste in the barrel through the cooling channel, so as to discharge the low-temperature waste from the discharge port. For example, if the waste is high-temperature dry slag, the high-temperature dry slag of about 500°C will continue to be cooled by the coolant in the cooling channel during the transmission process after entering the barrel through the feed port, and the temperature of the high-temperature dry slag will continue to decrease, and finally the low-temperature dry slag of about 50°C that meets the discharge requirements will be discharged from the discharge port. After the coolant in the cooling channel exchanges heat with the high-temperature waste, it will enter the heat exchanger to be cooled again, and will flow to the cooling channel again through the liquid storage tank to cool the high-temperature waste.

[0020] It can be seen that compared with the centralized cooling method, the cooling and conveying device of the present application continuously cools the high-temperature waste during its transmission, reducing the damage of the high temperature of the waste to the transmission device, ensuring normal transportation, and reducing safety accidents; and compared with the spray cooling method, the coolant in the cooling channel and the high-temperature waste are isolated from each other and do not directly contact each other, thereby avoiding the generation of steam and thus avoiding affecting the transmission. In summary, the cooling and conveying device of the present application can ensure the normal production operation of waste cooling and discharge, thereby ensuring the transmission efficiency.

[0049] In the related art, for some high-temperature wastes, such as high-temperature dry residues formed by high-temperature pyrolysis of oil-containing sludge in oil fields, the transmission efficiency of the transmission device used for its discharge is low and the cooling effect is poor. Therefore, the technical solution of this application is produced. Figure 1 to Figure 5 Describe in detail.

[0050] Example 1

[0051] This embodiment discloses a cooling and conveying device for discharging waste materials such as high-temperature dry residue after pyrolysis of oily sludge. The cooling and conveying device may include a spiral conveying device 10, a heat exchanger 20, a liquid storage tank 30 and a pump body 40.

[0052] The spiral conveying device 10 may include a barrel 11, a screw 12 and a motor 13. The screw 12 is arranged in the material cavity of the barrel 11 and can rotate in the barrel 11. The motor 13 is connected to the screw 12. To ensure torque transmission, a transmission mechanism 14 composed of a chain transmission mechanism or a belt transmission mechanism may be arranged between the screw 12 and the motor 13. The screw 12 is provided with a cooling channel 121 along the transmission direction of the waste material. The waste material here may be high-temperature dry residue after the pyrolysis of the oil-containing sludge. The barrel 11 is provided with a feed port 111 and a discharge port 112 in sequence along the transmission direction. The feed port 111 and the discharge port 112 are both connected to the material cavity of the barrel 11. The motor 13 can drive the screw 12 to rotate through the transmission mechanism 14, so that the waste material added into the material cavity of the barrel 11 from the feed port 111 is transmitted through the spiral transmission of the screw 12 and finally discharged from the discharge port 112.

[0053] The liquid storage tank 30 is used to store coolant, where the coolant can be clean water to facilitate local materials. Of course, other cooling structures can also be used. The cooling channel 121, the heat exchanger 20 and the liquid storage tank 30 are connected by the head and tail pipelines to form a cooling circulation pipeline. The pump body 40 is arranged in the cooling circulation pipeline, and the cooling channel 121 is connected to the liquid storage tank 30 through the pump body 40, or the cooling channel 121 is connected to the heat exchanger 20 through the pump body 40. Under the power generated by the pump body 40, the coolant in the liquid storage tank 30 can flow back to the liquid storage tank 30 through the cooling channel 121 of the screw 12 and the heat exchanger 20 in sequence.

[0054] In this way, after the high-temperature waste enters the barrel 11 through the feed port 111, the coolant can cool the waste in the barrel 11 through the cooling channel 121, so as to discharge the low-temperature waste from the discharge port 112. For example, if the waste is high-temperature dry slag, the high-temperature dry slag of about 500°C will continue to be cooled by the coolant in the cooling channel 121 during the transmission process after entering the barrel 11 through the feed port 111, and the temperature of the high-temperature dry slag will continue to decrease, and finally the low-temperature dry slag of about 50°C that meets the discharge requirements will be discharged from the discharge port 112. After the coolant in the cooling channel 121 exchanges heat with the high-temperature waste, it will enter the heat exchanger 20 to be cooled again, and will flow to the cooling channel 121 again through the liquid storage tank 30 to cool the high-temperature waste.

[0055] It can be seen that, compared with the centralized cooling method, the cooling and conveying device of this embodiment continuously cools the high-temperature waste during its transmission, reducing the damage of the high temperature of the waste to the conveying device, ensuring normal transportation, and reducing safety accidents; and compared with the spray cooling method, the coolant in the cooling channel 121 and the high-temperature waste are isolated from each other and do not directly contact, thereby avoiding the generation of steam and thus avoiding affecting the transmission. In summary, the cooling and conveying device of the present application can ensure the normal production operation of waste cooling and conveying, thereby ensuring the transmission efficiency.

[0056] It should be noted here that the motor 13 is speed-controlled. When the incoming waste material temperature is too high, the speed of the motor 13 can be lowered, and the waste material is slowly pushed forward in the barrel 11, thereby lengthening the heat exchange time and ensuring that the waste material discharged from the discharge port 112 is lower than the discharge temperature requirement. Conversely, if the incoming waste material temperature is relatively low, the speed of the motor 13 can be increased, and the waste material is quickly pushed forward in the barrel 11, thereby improving operating efficiency.

[0057] Optionally, the barrel 11 can be configured as a jacket structure. Specifically, the barrel 11 can have an inner wall and an outer wall, and a cooling chamber 113 is formed between the inner wall and the outer wall. The cooling chamber 113, the heat exchanger 20, and the liquid storage tank 30 are connected by end-to-end pipelines to form a cooling circulation pipeline system. In this way, the cooling chamber 113, the heat exchanger 20, and the liquid storage tank 30 form a closed-loop cooling circulation pipeline. The coolant in the liquid storage tank 30 can cool the high-temperature waste in the cooling chamber 113, and then cool it back to the liquid storage tank 30 through the heat exchanger 20, and the cycle is repeated continuously. It can be seen that in this embodiment, the coolant is cooled on the outside of the high-temperature waste through the cooling chamber 113, and on the inside of the high-temperature waste through the cooling channel 121. The dual-channel cooling method can have a better cooling effect on the waste.

[0058] Optionally, the cooling conveying device may further include a first control valve 51 and / or a second control valve 52, for example, the cooling conveying device is only provided with the first control valve 51, or only provided with the second control valve 52, or both the first control valve 51 and the second control valve 52 are provided. The first control valve 51 is provided between the spiral conveying device 10 and the liquid storage tank 30, and the coolant can enter the cooling channel 121 through the first control valve 51; the second control valve 52 is provided between the spiral conveying device 10 and the liquid storage tank 30, and the coolant can enter the cooling cavity 113 through the second control valve 52, so as to control the on-off timing of each cooling circulation pipeline, and facilitate the control of the cooling conveying device of the present application.

[0059] It should also be pointed out that the manner in which both the first control valve 51 and the second control valve 52 are set can also control the degree of cooling of the waste by the cooling and conveying device of the present application. Specifically, when the temperature of the waste entering the barrel 11 is too high, the first control valve 51 and the second control valve 52 are both opened. At this time, the waste is subjected to dual-channel cooling through the cooling chamber 113 and the cooling channel 121, thereby increasing the cooling degree and ensuring the cooling effect. When the temperature of the waste entering the barrel 11 is relatively low, only one of the first control valve 51 and the second control valve 52 can be opened. At this time, the waste is subjected to single-channel cooling through one of the cooling chamber 113 and the cooling channel 121, thereby reducing the cooling degree and ensuring the adaptation of the cooling degree and the waste temperature.

[0060] Optionally, the cooling conveying device may further include a first one-way valve 61 and / or a second one-way valve 62, for example, only the first one-way valve 61 is provided, or only the second one-way valve 62 is provided, or both the first one-way valve 61 and the second one-way valve 62 are provided. The first one-way valve 61 is provided between the spiral conveying device 10 and the heat exchanger 20, and the coolant in the cooling channel 121 can enter the heat exchanger 20 through the first one-way valve 61 to prevent the uncooled coolant from flowing back into the cooling channel 121. The second one-way valve 62 is provided between the spiral conveying device 10 and the heat exchanger 20, and the coolant in the cooling cavity 113 can enter the heat exchanger 20 through the second one-way valve 62 to prevent the uncooled coolant from flowing back into the cooling cavity 113.

[0061] Example 2

[0062] This embodiment is further designed as follows based on the embodiment 1.

[0063] The height of the position where the spiral conveyor 10 is located, the height of the position where the heat exchanger 20 is located, and the height of the position where the pump body 40 is located are all greater than the height of the position where the liquid storage tank 30 is located, and the direction of the height is the direction of gravity. In this way, when the cooling conveying device stops working, the coolant remaining in the spiral conveyor 10, the heat exchanger 20 and the pump body 40 can all flow back to the liquid storage tank 30 for storage.

[0064] Optionally, the spiral conveyor 10 may further include a first support rod 15 and a second support rod 16, both of which are supported and arranged between the barrel 11 and the ground, wherein the first support rod 15 is arranged close to the feed port 111, and the second support rod 16 is arranged close to the discharge port 112, and the length of the first support rod 15 is less than the length of the second support rod 16, so that the spiral conveyor 10 is arranged obliquely. The length direction of the first support rod 15 and the length direction of the second support rod 16 may both be along the direction of gravity.

[0065] It can be seen that by tilting the spiral conveying device 10, the height of the entrance of the cooling channel 121 will be smaller than the height of the exit of the cooling channel 121, and the height of the entrance of the cooling chamber 113 will be smaller than the height of the exit of the cooling chamber 113. Therefore, when the cooling conveying device stops working, the coolant in the cooling channel 121 and the cooling chamber 113 can flow back to the liquid storage tank 30 to prevent residue.

[0066] Optionally, the screw 12 may include a rotating shaft 122 and a spiral blade 123 disposed on the rotating shaft 122, the cooling channel 121 is disposed on the rotating shaft 122, and the motor 13 is connected to the rotating shaft 122. The driving force provided by the motor 13 causes the spiral blade 123 to rotate with the rotating shaft 122, thereby realizing the spiral transmission and conveying of the waste by the screw 12 and realizing the stirring of the waste during the conveying process.

[0067] A scraper 124 is provided at the outer edge of the spiral blade 123 near the barrel 11. The scraper 124 can scrape off the waste remaining on the inner wall of the barrel 11 to prevent the waste from accumulating and sticking. It can also improve the stirring ability of the spiral conveyor 10. Sufficient stirring can improve the cooling effect on the waste.

[0068] Optionally, a plurality of scrapers 124 may be provided along the spiral extension direction of the spiral blade 123 , so as to further improve the scraping effect on the waste material remaining on the inner wall of the barrel 11 .

[0069] Optionally, both ends of the screw 12 extend out of the barrel 11 so that the cooling channel 121 is respectively connected to the heat exchanger 20 and the liquid storage tank 30. At the same time, the feed port 111, the discharge port 112, and the inlet and outlet of the cooling chamber 113 are all arranged on the barrel circumferential wall of the barrel 11, and the feed port 111 and the discharge port 112 are both located between the inlet and outlet of the cooling chamber 113. In this way, it can be ensured that the waste is cooled by the cooling channel 121 and the cooling chamber 113 during the entire journey of transmission in the spiral conveyor 10, thereby ensuring the cooling effect.

[0070] Optionally, the feed port 111 of the barrel 11 is arranged close to the liquid storage tank 30, and the discharge port 112 of the barrel 11 is arranged close to the heat exchanger 20. In this way, the transmission direction of the waste material is consistent with the transmission direction of the coolant, which better ensures the cooling effect of the waste material.

[0071] Example 3

[0072] This embodiment discloses a method for using a cooling and conveying device, which is described below by taking the waste material being high-temperature dry residue after pyrolysis of oil-containing sludge in an oil field as an example.

[0073] The pump body 40 is turned on to allow the coolant in the liquid storage tank 30 to circulate and fill the cooling circulation pipeline system composed of the cooling cavity 113, the cooling channel 121, the heat exchanger 20, the pump body 40 and the liquid storage tank 30.

[0074] The motor 13 is started to drive the screw rod 12 to rotate.

[0075] The high-temperature dry slag is added into the material cavity of the barrel 11 from the feed port 111, so that the high-temperature dry slag is transferred to the discharge port 112 under the rotation of the screw 12 for discharge. In this process, the heat of the high-temperature dry slag will be heat-exchanged with the coolant in the cooling channel 121 and the cooling cavity 113, so that when the high-temperature dry slag reaches the discharge port 112, the temperature can be reduced to below 50°C, and the coolant in the cooling channel 121 and the cooling cavity 113 will be circulated to the heat exchanger 20 after the temperature is increased by heat exchange, and will return to the low-temperature state after being cooled by the heat exchanger 20, and will flow back to the cooling channel 121 and the cooling cavity 113 again through the liquid storage tank 30, and the cycle will be repeated continuously.

[0076] After the high-temperature dry slag is transported, the motor 13 is stopped.

[0077] The pump body 40 continues to work until the water temperature at various locations in the cooling circulation pipeline system is consistent and then the pump body 40 is turned off.

[0078] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
