Description

Technical Field

[0001] The utility model relates to the technical field of mixing equipment, and particularly relates to a heating device for a mixing equipment. Background Art

[0002] The high-temperature salt-resistant fluid loss reducer is a functional chemical additive designed specifically for oil drilling operations and is mainly used in the drilling fluid system. It has high-temperature resistance, salt resistance, and fluid loss reduction properties. In the process of producing the high-temperature salt-resistant fluid loss reducer, mixing is a key step, which involves uniformly mixing various raw materials or additives to ensure the performance stability and consistency of the final product.

[0003] When the existing mixing equipment mixes raw materials, due to the humid air in the Sichuan-Chongqing region, the raw materials are easily adsorbed on the inner wall of the mixing tank and the conveying port of the screw feeder, resulting in the water content of the produced high-temperature salt-resistant fluid loss reducer being greater than the index requirement of 15%, and the qualified rate of sampling inspection being 50%-60%, which cannot meet the production requirements. Content of the Utility Model

[0004] In view of the above problems in the prior art, the utility model provides a heating device for a mixing equipment, which solves the problem that the water content of the product of the existing mixing equipment is greater than the index requirement due to the high air humidity in the region.

[0007] In this scheme, external air is sent into the heating device by the blower for heating to form hot air at 200°C, and the hot air enters the mixing tank to dry the raw materials in the mixing tank, so that the raw materials will not be adsorbed on the inner wall of the mixing tank and the conveying port of the screw feeder, making the water content of the product less than the index requirement and meeting the production requirements. Moreover, the controller can detect the hot air temperature at the air outlet of the heater through the temperature sensor, which is convenient for adjusting the temperature of the heater to make the hot air temperature the same as the set temperature.

[0008] Further, the heater includes a housing with heating wires disposed therein. The air inlets and outlets of the housing are both honeycomb-shaped. The honeycomb shape of the housing enables the incoming air to be more evenly distributed when passing through numerous small holes, which can make the heat distribution during the heating process more balanced, avoid problems such as local overheating or uneven heating, and improve the heating efficiency and the stability of the heating effect. Moreover, the geometric shape of the honeycomb structure itself has relatively high structural strength and can maintain good stability even in high-temperature environments, which is beneficial to extending the service life of the heating device.

[0009] Further, the motor of the blower is electrically connected to an inverter, and the inverter is electrically connected to a controller. The controller can change the speed of the motor through the inverter, thereby adjusting the air speed of the blower.

[0010] Further, a touch screen is embedded on the door of the electric control box, and the touch screen is electrically connected to the controller. Workers can conveniently set the air speed of the blower and the temperature of the heating device through the touch screen.

[0011] Further, an alarm is provided on the electric control box, and the alarm is electrically connected to the controller. When the controller detects that the hot air temperature of the heater is too high through a temperature sensor, or detects that the temperature difference between the air inlet and outlet of the blower is abnormal, the controller can sound the alarm to remind the worker to carry out maintenance.

[0012] Further, the mixing device further includes a bracket, which includes a first support plate and a second support plate. The mixing tank is fixed on the first support plate, and the housing is fixed on the lower surface of the second support plate.

[0013] Further, the air outlet of the housing is communicated with the mixing tank through an air pipe.

[0014] Further, a breathable cover is provided at the air outlet of the air pipe. The breathable cover prevents the raw materials in the mixing tank from entering the air pipe.

[0015] Further, the height of the second support plate is greater than that of the first support plate, and a vertical staircase for accessing the second support plate is provided on the bracket. The provision of the vertical staircase facilitates the worker to stand on the second support plate for feeding and maintenance.

[0016] Further, the heating wire is made of nickel-chromium wire. The hot air formed by heating the air through the nickel-chromium wire is non-toxic and odorless.

[0017] The present utility model discloses a heating device for a mixing device, and its beneficial effects are as follows:

[0018] The utility model sends external air into a heating device through a blower for heating to form hot air at 200°C. The hot air enters the mixing tank and dries the raw materials in the mixing tank, so that the raw materials will not adhere to the wall of the mixing tank and the feeding port of the screw feeder, making the moisture content of the product less than the index requirement and meeting the production requirements.

Moreover, the geometric shape of the honeycomb structure itself has relatively high structural strength and can maintain good stability even in a high-temperature environment, which is beneficial to extending the service life of the heating device.

[0029] Specifically, the motor of the blower 11 is electrically connected to a frequency converter, and the frequency converter is electrically connected to the controller. The controller can change the speed of the motor through the frequency converter, thereby adjusting the wind speed of the blower 11.
